Details

    Description

      Support CHECK constraint as in (or close to) SQL Standard.

      The following syntaxes will be supported (they are already supported by the current MariaDB parser, but does nothing):

      As part of column definition:
      CREATE TABLE t1 (a int check (A > 10));

      As an independent constraint:
      CREATE TABLE t1 (a int, constraint `A` CHECK (A > 10));

      ALTER TABLE DROP CONSTRAINT `A`;
