      Description

      Table and database level CHARACTER SET and COLLATE clauses can go in any order. So both these syntaxes are correct:

      • CHARACTER SET .. COLLATE
      • COLLATE .. CHARACTER SET

      But they can produce errors differently:

      CREATE OR REPLACE TABLE t1 (a CHAR) COLLATE latin1_bin CHARACTER SET DEFAULT;
      

      ERROR 1302 (HY000): Conflicting declarations: 'CHARACTER SET latin1' and 'CHARACTER SET DEFAULT'
      

      CREATE OR REPLACE  TABLE t1 (a CHAR) CHARACTER SET DEFAULT COLLATE latin1_bin;
      

      Query OK, 0 rows affected (0.014 sec)
      

      The same problem is repeatable on the database level:

      CREATE OR REPLACE DATABASE db1 COLLATE latin1_bin CHARACTER SET DEFAULT;
      

      ERROR 1302 (HY000): Conflicting declarations: 'CHARACTER SET latin1' and 'CHARACTER SET DEFAULT'
      

      CREATE OR REPLACE DATABASE db1 CHARACTER SET DEFAULT COLLATE latin1_bin;
      

      Query OK, 0 rows affected (0.014 sec)
