If we want to get more details about the columns of an existing table, then we need to use SHOW FULL COLUMNS statement. Consider the following example where the SHOW FULL COLUMNS statement has been applied to the "Employee" table and MySQL returns a result set with some additional details about the table columns such as collation, permissions, and comments -
mysql> SHOW FULL COLUMNS FROM EMPLOYEE\G *************************** 1. row *************************** Field: Id Type: int(11) Collation: NULL Null: YES Key: Default: NULL Extra: Privileges: select,insert,update,references Comment: *************************** 2. row *************************** Field: Name Type: varchar(20) Collation: latin1_swedish_ci Null: YES Key: Default: NULL Extra: Privileges: select,insert,update,references Comment: 2 rows in set (0.13 sec)
