    Description

      If I specify mutiple conflicting COLLATE clauses on the column level, no error is raised:

      CREATE OR REPLACE TABLE t1 (a CHAR(10) COLLATE latin1_swedish_ci NOT NULL COLLATE latin1_bin);
      		 
      SHOW CREATE TABLE t1;


      +-------+----------------------------------------------------------------------------------------------------------------------------+
      		 
      | Table | Create Table                                                                                                               |
      		 
      +-------+----------------------------------------------------------------------------------------------------------------------------+
      		 
      | t1    | CREATE TABLE `t1` (
      		 
        `a` char(10) CHARACTER SET latin1 COLLATE latin1_bin NOT NULL
      		 
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
      		 
      +-------+----------------------------------------------------------------------------------------------------------------------------+

      Notice, the first COLLATE was ignored, the last COLLATE was used.

      The same problem is repeatable on the table level. See MDEV-28117.
