    Description

      This script:

      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 (a INT);
      ALTER TABLE t1 ADD CONSTRAINT c1 CHECK (a > 0);
      ALTER TABLE t1 ADD CONSTRAINT c1 CHECK (a > 0);
      SHOW CREATE TABLE t1;
      

      returns:

      CREATE TABLE `t1` (
        `a` int(11) DEFAULT NULL,
        CONSTRAINT `c1` CHECK (a > 0),
        CONSTRAINT `c1` CHECK (a > 0)
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1 
      

      Notice, two constrains with a duplicate name are allowed.
