Return Values
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:
|
||||||||
| 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_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. | ||||||||
| IS_NULLABLE | A string value where 'YES' means that the parameter accepts or returns null values and 'NO' means that the parameter does not accept or return null values. |
