This parameter accepts a search pattern containing _ and % as wildcards. parameter The name of the parameter. This parameter accepts a search pattern containing _ and % as wildcards. If this parameter is &null;, all parameters for the specified stored procedures are returned. &reftitle.returnvalues; Returns a statement resource with a result set containing rows describing the parameters for the stored procedures matching the specified parameters. The rows are composed of the following columns: Column name Description PROCEDURE_CAT The catalog that contains the procedure. The value is &null; if this table does not have catalogs. 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. NUM_PREC_RADIX An integer value of either 10 (representing an exact numeric data type), 2 (representing an approximate numeric data type), or &null; (representing a data type for which radix is not applicable). NULLABLE An integer value representing whether the parameter is nullable or not. REMARKS Description of the parameter. COLUMN_DEF Default value for the parameter. SQL_DATA_TYPE An integer value representing the size of the parameter. SQL_DATETIME_SUB Returns an integer value representing a datetime subtype code, or &null; for SQL data types to which this does not apply. CHAR_OCTET_LENGTH Maximum length in octets for a character data type parameter, which matches COLUMN_SIZE for single-byte character set data, or &null; for non-character data types. ORDINAL_POSITION The 1-indexed position of the parameter in the CALL statement.
