Methods Summary
public void	addBatch() Adds a set of parameters to this PreparedStatement object's batch of commands. exception SQLException if a database access error occurs or this method is called on a closed PreparedStatement see Statement#addBatch since 1.2
public void	clearParameters() Clears the current parameter values immediately. In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters. exception SQLException if a database access error occurs or this method is called on a closed PreparedStatement
public boolean	execute() Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery and executeUpdate. The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s). return true if the first result is a ResultSet object; false if the first result is an update count or there is no result exception SQLException if a database access error occurs; this method is called on a closed PreparedStatement or an argument is supplied to this method see Statement#execute see Statement#getResultSet see Statement#getUpdateCount see Statement#getMoreResults
public java.sql.ResultSet	executeQuery() Executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query. return a ResultSet object that contains the data produced by the query; never null exception SQLException if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement does not return a ResultSet object
public int	executeUpdate() Executes the SQL statement in this PreparedStatement object, which must be an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement. return either (1) the row count for SQL Data Manipulation Language (DML) statements or (2) 0 for SQL statements that return nothing exception SQLException if a database access error occurs; this method is called on a closed PreparedStatement or the SQL statement returns a ResultSet object
public java.sql.ResultSetMetaData	getMetaData() Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed. Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned. NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support. return the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object exception SQLException if a database access error occurs or this method is called on a closed PreparedStatement exception SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.2
public java.sql.ParameterMetaData	getParameterMetaData() Retrieves the number, types and properties of this PreparedStatement object's parameters. return a ParameterMetaData object that contains information about the number, types and properties for each parameter marker of this PreparedStatement object exception SQLException if a database access error occurs or this method is called on a closed PreparedStatement see ParameterMetaData since 1.4
public void	setArray(int parameterIndex, java.sql.Array x) Sets the designated parameter to the given java.sql.Array object. The driver converts this to an SQL ARRAY value when it sends it to the database. param parameterIndex the first parameter is 1, the second is 2, ... param x an Array object that maps an SQL ARRAY value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.2
public void	setAsciiStream(int parameterIndex, java.io.InputStream x, int length) Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream.

Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface. Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setAsciiStream which takes a length parameter. param parameterIndex the first parameter is 1, the second is 2, ... param x the Java input stream that contains the ASCII parameter value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface. param parameterIndex the first parameter is 1, the second is 2, ... param x the java input stream which contains the binary parameter value param length the number of bytes in the stream exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement since 1.6
public void	setBinaryStream(int parameterIndex, java.io.InputStream x) Sets the designated parameter to the given input stream. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface. Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setBinaryStream which takes a length parameter. param parameterIndex the first parameter is 1, the second is 2, ... param x the java input stream which contains the binary parameter value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6

The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface. Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setCharacterStream which takes a length parameter. param parameterIndex the first parameter is 1, the second is 2, ... param reader the java.io.Reader object that contains the Unicode data exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6

public void	setClob(int parameterIndex, java.io.Reader reader, long length) Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB param parameterIndex index of the first parameter is 1, the second is 2, ... param reader An object that contains the data to set the parameter value to. param length the number of characters in the parameter data. throws SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or if the length specified is less than zero. throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6
public void	setClob(int parameterIndex, java.io.Reader reader) Sets the designated parameter to a Reader object. This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setClob which takes a length parameter. param parameterIndex index of the first parameter is 1, the second is 2, ... param reader An object that contains the data to set the parameter value to. throws SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatementor if parameterIndex does not correspond to a parameter marker in the SQL statement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6

public void	setDate(int parameterIndex, java.sql.Date x, java.util.Calendar cal) Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database.

public void	setNCharacterStream(int parameterIndex, java.io.Reader value) Sets the designated parameter to a Reader object. The Reader reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

public void	setNClob(int parameterIndex, java.io.Reader reader, long length) Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB param parameterIndex index of the first parameter is 1, the second is 2, ... param reader An object that contains the data to set the parameter value to. param length the number of characters in the parameter data. throws SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if the length specified is less than zero; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6

This method differs from the setCharacterStream (int, Reader) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setNClob which takes a length parameter. param parameterIndex index of the first parameter is 1, the second is 2, ... param reader An object that contains the data to set the parameter value to. throws SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6
public void	setNString(int parameterIndex, java.lang.String value) Sets the designated paramter to the given String object.

public void	setNull(int parameterIndex, int sqlType) Sets the designated parameter to SQL NULL. Note: You must specify the parameter's SQL type. param parameterIndex the first parameter is 1, the second is 2, ... param sqlType the SQL type code defined in java.sql.Types exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement exception SQLFeatureNotSupportedException if sqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type
public void	setNull(int parameterIndex, int sqlType, java.lang.String typeName) Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types. Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored. param parameterIndex the first parameter is 1, the second is 2, ... param sqlType a value from java.sql.Types param typeName the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement exception SQLFeatureNotSupportedException if sqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type or if the JDBC driver does not support this method since 1.2
public void	setObject(int parameterIndex, java.lang.Object x, int targetSqlType) Sets the value of the designated parameter with the given object. This method is like the method setObject above, except that it assumes a scale of zero. param parameterIndex the first parameter is 1, the second is 2, ... param x the object containing the input parameter value param targetSqlType the SQL type (as defined in java.sql.Types) to be sent to the database exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement exception SQLFeatureNotSupportedException if targetSqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type see Types
public void	setObject(int parameterIndex, java.lang.Object x) Sets the value of the designated parameter using the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types. The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database. Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, RowId, SQLXML or Array, the driver should pass it to the database as a value of the corresponding SQL type. Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the setNull or the setObject(int parameterIndex, Object x, int sqlType) method should be used instead of setObject(int parameterIndex, Object x). Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above. param parameterIndex the first parameter is 1, the second is 2, ... param x the object containing the input parameter value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or the type of the given object is ambiguous
public void	setObject(int parameterIndex, java.lang.Object x, int targetSqlType, int scaleOrLength) Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed. The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type. Note that this method may be used to pass database-specific abstract data types. param parameterIndex the first parameter is 1, the second is 2, ... param x the object containing the input parameter value param targetSqlType the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type. param scaleOrLength for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored. exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero exception SQLFeatureNotSupportedException if targetSqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type see Types since 1.6
public void	setRef(int parameterIndex, java.sql.Ref x) Sets the designated parameter to the given REF(<structured-type>) value. The driver converts this to an SQL REF value when it sends it to the database. param parameterIndex the first parameter is 1, the second is 2, ... param x an SQL REF value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.2
public void	setRowId(int parameterIndex, java.sql.RowId x) Sets the designated parameter to the given java.sql.RowId object. The driver converts this to a SQL ROWID value when it sends it to the database param parameterIndex the first parameter is 1, the second is 2, ... param x the parameter value throws SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6
public void	setSQLXML(int parameterIndex, java.sql.SQLXML xmlObject) Sets the designated parameter to the given java.sql.SQLXML object. The driver converts this to an SQL XML value when it sends it to the database. param parameterIndex index of the first parameter is 1, the second is 2, ... param xmlObject a SQLXML object that maps an SQL XML value throws SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or the java.xml.transform.Result, Writer or OutputStream has not been closed for the SQLXML object throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.6
public void	setShort(int parameterIndex, short x) Sets the designated parameter to the given Java short value. The driver converts this to an SQL SMALLINT value when it sends it to the database. param parameterIndex the first parameter is 1, the second is 2, ... param x the parameter value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
public void	setString(int parameterIndex, java.lang.String x) Sets the designated parameter to the given Java String value. The driver converts this to an SQL VARCHAR or LONGVARCHAR value (depending on the argument's size relative to the driver's limits on VARCHAR values) when it sends it to the database. param parameterIndex the first parameter is 1, the second is 2, ... param x the parameter value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
public void	setTime(int parameterIndex, java.sql.Time x) Sets the designated parameter to the given java.sql.Time value. The driver converts this to an SQL TIME value when it sends it to the database. param parameterIndex the first parameter is 1, the second is 2, ... param x the parameter value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
public void	setTime(int parameterIndex, java.sql.Time x, java.util.Calendar cal) Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application. param parameterIndex the first parameter is 1, the second is 2, ... param x the parameter value param cal the Calendar object the driver will use to construct the time exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement since 1.2
public void	setTimestamp(int parameterIndex, java.sql.Timestamp x) Sets the designated parameter to the given java.sql.Timestamp value. The driver converts this to an SQL TIMESTAMP value when it sends it to the database. param parameterIndex the first parameter is 1, the second is 2, ... param x the parameter value exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement
public void	setTimestamp(int parameterIndex, java.sql.Timestamp x, java.util.Calendar cal) Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application. param parameterIndex the first parameter is 1, the second is 2, ... param x the parameter value param cal the Calendar object the driver will use to construct the timestamp exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement since 1.2
public void	setURL(int parameterIndex, java.net.URL x) Sets the designated parameter to the given java.net.URL value. The driver converts this to an SQL DATALINK value when it sends it to the database. param parameterIndex the first parameter is 1, the second is 2, ... param x the java.net.URL object to be set exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement throws SQLFeatureNotSupportedException if the JDBC driver does not support this method since 1.4
public void	setUnicodeStream(int parameterIndex, java.io.InputStream x, int length) Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from Unicode to the database char format. The byte format of the Unicode stream must be a Java UTF-8, as defined in the Java Virtual Machine Specification. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface. param parameterIndex the first parameter is 1, the second is 2, ... param x a java.io.InputStream object that contains the Unicode parameter value param length the number of bytes in the stream exception SQLException if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement exception SQLFeatureNotSupportedException if the JDBC driver does not support this method deprecated
