CallableStatement

public interface CallableStatement implements PreparedStatement
The interface used to execute SQL stored procedures. The JDBC API provides a stored procedure SQL escape syntax that allows stored procedures to be called in a standard way for all RDBMSs. This escape syntax has one form that includes a result parameter and one that does not. If used, the result parameter must be registered as an OUT parameter. The other parameters can be used for input, output or both. Parameters are referred to sequentially, by number, with the first parameter being 1.
{?= call <procedure-name>[<arg1>,<arg2>, ...]}
{call <procedure-name>[<arg1>,<arg2>, ...]}

IN parameter values are set using the set methods inherited from {@link PreparedStatement}. The type of all OUT parameters must be registered prior to executing the stored procedure; their values are retrieved after execution via the get methods provided here.

A CallableStatement can return one {@link ResultSet} object or multiple ResultSet objects. Multiple ResultSet objects are handled using operations inherited from {@link Statement}.

For maximum portability, a call's ResultSet objects and update counts should be processed prior to getting the values of output parameters.

public voidregisterOutParameter(int paramIndex, int sqlType, java.lang.String typeName)
Registers the designated output parameter. This version of the method registerOutParameter should be used for a user-defined or REF output parameter. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types. Before executing a stored procedure call, you must explicitly call registerOutParameter to register the type from java.sql.Types for each OUT parameter. For a user-defined parameter, the fully-qualified SQL type name of the parameter should also be given, while a REF parameter requires that the fully-qualified type name of the referenced type be given. A JDBC driver that does not need the type code and type name information may ignore it. To be portable, however, applications should always provide these values for user-defined and REF parameters. Although it is intended for user-defined and REF parameters, this method may be used to register a parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the typeName parameter is ignored.

Note: When reading the value of an out parameter, you must use the getter method whose Java type corresponds to the parameter's registered SQL type.

public voidsetBytes(java.lang.String parameterName, byte[] x)
Sets the designated parameter to the given Java array of bytes. The driver converts this to an SQL VARBINARY or LONGVARBINARY (depending on the argument's size relative to the driver's limits on VARBINARY values) when it sends it to the database.

public voidsetCharacterStream(java.lang.String parameterName, java.io.Reader reader, int length)
Sets the designated parameter to the given Reader object, which is the given number of characters long. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader 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.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

param
parameterName the name of the parameter
param
reader the java.io.Reader object that contains the UNICODE data used as the designated parameter
param
length the number of characters in the stream

public voidsetDate(java.lang.String parameterName, 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. With a a Calendar object, the driver can calculate the date 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.

public voidsetNull(java.lang.String parameterName, int sqlType)
Sets the designated parameter to SQL NULL.

Note: You must specify the parameter's SQL type.

exception
SQLException if a database access error occurs

1.4

public voidsetNull(java.lang.String parameterName, 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
parameterName the name of the parameter
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 SQL REF value

SQLException if a database access error occurs

public voidsetObject(java.lang.String parameterName, java.lang.Object x, int targetSqlType, int scale)
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.

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, Struct, 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 datatabase- specific abstract data types.

param
parameterName the name of the parameter
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
scale for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.

public voidsetObject(java.lang.String parameterName, 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.

public voidsetObject(java.lang.String parameterName, java.lang.Object x)
Sets the value of the designated parameter with 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, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

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
parameterName the name of the parameter
param
x the object containing the input parameter value
exception
SQLException if a database access error occurs or if the given Object parameter is ambiguous
