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 | ' value | |
TABLE_CATALOG | NULL | |

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 ...
