ParameterMetaData

Fields Summary
int	parameterNoNulls The constant indicating that a parameter will not allow NULL values.
int	parameterNullable The constant indicating that a parameter will allow NULL values.
int	parameterNullableUnknown The constant indicating that the nullability of a parameter is unknown.
int	parameterModeUnknown The constant indicating that the mode of the parameter is unknown.
int	parameterModeIn The constant indicating that the parameter's mode is IN.
int	parameterModeInOut The constant indicating that the parameter's mode is INOUT.
int	parameterModeOut The constant indicating that the parameter's mode is OUT.

Methods Summary
public java.lang.String	getParameterClassName(int param) Retrieves the fully-qualified name of the Java class whose instances should be passed to the method PreparedStatement.setObject. param param the first parameter is 1, the second is 2, ... return the fully-qualified name of the class in the Java programming language that would be used by the method PreparedStatement.setObject to set the value in the specified parameter. This is the class name used for custom mapping. exception SQLException if a database access error occurs since 1.4
public int	getParameterCount() Retrieves the number of parameters in the PreparedStatement object for which this ParameterMetaData object contains information. return the number of parameters exception SQLException if a database access error occurs since 1.4
public int	getParameterMode(int param) Retrieves the designated parameter's mode. param param the first parameter is 1, the second is 2, ... return mode of the parameter; one of ParameterMetaData.parameterModeIn, ParameterMetaData.parameterModeOut, or ParameterMetaData.parameterModeInOut ParameterMetaData.parameterModeUnknown. exception SQLException if a database access error occurs since 1.4
public int	getParameterType(int param) Retrieves the designated parameter's SQL type. param param the first parameter is 1, the second is 2, ... return SQL type from java.sql.Types exception SQLException if a database access error occurs since 1.4 see Types
public java.lang.String	getParameterTypeName(int param) Retrieves the designated parameter's database-specific type name. param param the first parameter is 1, the second is 2, ... return type the name used by the database. If the parameter type is a user-defined type, then a fully-qualified type name is returned. exception SQLException if a database access error occurs since 1.4
public int	getPrecision(int param) Retrieves the designated parameter's specified column size. The returned value represents the maximum column size for the given parameter. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. 0 is returned for data types where the column size is not applicable. param param the first parameter is 1, the second is 2, ... return precision exception SQLException if a database access error occurs since 1.4
public int	getScale(int param) Retrieves the designated parameter's number of digits to right of the decimal point. 0 is returned for data types where the scale is not applicable. param param the first parameter is 1, the second is 2, ... return scale exception SQLException if a database access error occurs since 1.4
public int	isNullable(int param) Retrieves whether null values are allowed in the designated parameter. param param the first parameter is 1, the second is 2, ... return the nullability status of the given parameter; one of ParameterMetaData.parameterNoNulls, ParameterMetaData.parameterNullable, or ParameterMetaData.parameterNullableUnknown exception SQLException if a database access error occurs since 1.4
public boolean	isSigned(int param) Retrieves whether values for the designated parameter can be signed numbers. param param the first parameter is 1, the second is 2, ... return true if so; false otherwise exception SQLException if a database access error occurs since 1.4
