ROUTINE_SCHEMA	Database name associated with the routine.
ROUTINE_NAME	Name of the routine.
ROUTINE_TYPE	Whether the routine is a PROCEDURE or a FUNCTION.
DATA_TYPE	The return value's data type (for stored functions).
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.
PARAMETER_STYLE	Always SQL.
IS_DETERMINISTIC	Whether the routine is deterministic (can produce only one result for a given list of parameters) or not.
SQL_DATA_ACCESS	One of READS SQL DATA, MODIFIES SQL DATA, CONTAINS SQL, or NO SQL.
SQL_PATH	Always NULL.
SECURITY_TYPE	INVOKER or DEFINER. Indicates which user's privileges apply to this routine.
CREATED	Date and time the routine was created.
LAST_ALTERED	Date and time the routine was last changed.
SQL_MODE	The SQL_MODE at the time the routine was created.
ROUTINE_COMMENT	Comment associated with the routine.
DEFINER	If the SECURITY_TYPE is DEFINER, this value indicates which user defined this routine.
CHARACTER_SET_CLIENT	The character set used by the client that created the routine.
COLLATION_CONNECTION	The collation (and character set) used by the connection that created the routine.
DATABASE_COLLATION	The default collation (and character set) for the database, at the time the routine was created.

It provides information similar to, but more complete, than the SHOW PROCEDURE STATUS and SHOW FUNCTION STATUS statements.

For information about the parameters accepted by the routine, you can query the information_schema.PARAMETERS table.
