| 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. |
