    According to the MySQL Documentation, these values are just copied from the mysql.db table. All this does is provide an alternative way to find all users who have been granted a database-level privilege.

    Here is a breakdown of what each column represents

    • GRANTEE is mysql user that had the privilege granted (user@host from mysql.db)
    • TABLE_CATALOG is a field defined for this table to be SQL-92 compatiple
    • TABLE_SCHEMA is the database whose grants are allowed (db column in mysql.db)
    • PRIVILEGE_TYPE is the individual database-level privilege granted in mysql.db
      • Select_priv
      • Insert_priv
      • Update_priv
      • Delete_priv
      • Create_priv
      • Drop_priv
      • References_priv
      • Index_priv
      • Alter_priv
      • Create_tmp_table_priv
      • Lock_tables_priv
      • Create_view_priv
      • Show_view_priv
      • Create_routine_priv
      • Event_priv
      • Trigger_priv
    • IS_GRANTABLE tells you if the user was defined WITH GRANTS (Grant_priv column of mysql.db) . In other words, the value tells whether or not the mysql user can give away the specific database-level privilege to other mysql users
