20.8 The `INFORMATION_SCHEMA COLUMN_PRIVILEGES' Table
=====================================================
The `COLUMN_PRIVILEGES' table provides information about column
privileges. This information comes from the `mysql.columns_priv' grant
table.
*`INFORMATION_SCHEMA' Name* *`SHOW' Name* *Remarks*
`GRANTEE' `'USER_NAME'@'HOST_NAME''
value
`TABLE_CATALOG' `NULL'
`TABLE_SCHEMA'
`TABLE_NAME'
`COLUMN_NAME'
`PRIVILEGE_TYPE'
`IS_GRANTABLE'
Notes:
* In the output from `SHOW FULL COLUMNS', the privileges are all in
one field and in lowercase, for example,
`select,insert,update,references'. In `COLUMN_PRIVILEGES', there
is one privilege per row, in uppercase.
* `PRIVILEGE_TYPE' can contain one (and only one) of these values:
`SELECT', `INSERT', `UPDATE', `REFERENCES'.
* If the user has `GRANT OPTION' privilege, `IS_GRANTABLE' should be
`YES'. Otherwise, `IS_GRANTABLE' should be `NO'. The output does
not list `GRANT OPTION' as a separate privilege.
The following statements are _not_ equivalent:
SELECT ... FROM INFORMATION_SCHEMA.COLUMN_PRIVILEGES
SHOW GRANTS ...
