PROCEDURE_SCHEM	Name of the schema that contains the stored procedure.
PROCEDURE_NAME	Name of the procedure.
COLUMN_NAME	Name of the parameter.
COLUMN_TYPE	An integer value representing the type of the parameter: Return value Parameter type 1 (SQL_PARAM_INPUT) Input (IN) parameter. 2 (SQL_PARAM_INPUT_OUTPUT) Input/output (INOUT) parameter. 3 (SQL_PARAM_OUTPUT) Output (OUT) parameter.
DATA_TYPE	The SQL data type for the parameter represented as an integer value.
TYPE_NAME	A string representing the data type for the parameter.
COLUMN_SIZE	An integer value representing the size of the parameter.
BUFFER_LENGTH	Maximum number of bytes necessary to store data for this parameter.
DECIMAL_DIGITS	The scale of the parameter, or null where scale is not applicable.
