CHARACTER_MAXIMUM_LENGTH | Maximum length. |
CHARACTER_OCTET_LENGTH | Same as the CHARACTER_MAXIMUM_LENGTH except for multi-byte character sets. |
NUMERIC_PRECISION | For numeric types, the precision (number of significant digits) for the column. NULL if not a numeric field. |
NUMERIC_SCALE | For numeric types, the scale (significant digits to the right of the decimal point). NULL if not a numeric field. |
DATETIME_PRECISION | Fractional-seconds precision, or NULL if not a time data type. |
CHARACTER_SET_NAME | Character set if a non-binary string data type, otherwise NULL. |
COLLATION_NAME | Collation if a non-binary string data type, otherwise NULL. |
DATA_TYPE | The column's data type. |
ROUTINE_BODY | Always SQL. |
ROUTINE_DEFINITION | Definition of the routine. |
EXTERNAL_NAME | Always NULL. |
EXTERNAL_LANGUAGE | Always SQL. |
