An object that can be used to get information about the types and properties for each parameter marker in a PreparedStatement object. For some queries and driver implementations, the data that would be returned by a ParameterMetaData object may not be available until the PreparedStatement has been executed.
Some driver implementations may not be able to provide information about the types and properties for each parameter marker in a CallableStatement object.

- Returns
-
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.

Retrieves the designated parameter's database-specific type name.
Value parameters

Retrieves the designated parameter's specified column size.
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.
