SP variables of the SET data type erroneously allow values with comma

Details

    Description

      Comma is not allowed in SET values in a field definition:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a SET('a','b','c','a,b'));


      ERROR 1367 (22007): Illegal set 'a,b' value found during parsing

      SP variables erroneously allow commas:

      DROP PROCEDURE IF EXISTS p1;
      		 
      DELIMITER $$
      		 
      CREATE PROCEDURE p1()
      		 
      BEGIN
      		 
        DECLARE a SET('a','b','c','a,b');
      		 
        SET a='a,b';
      		 
        SELECT a, a+0;
      		 
      END;
      		 
      $$
      		 
      DELIMITER ;
      		 
      CALL p1();

      Notice, the 'a,b' value is ignored.
      Inserting assigning 'a,b' to the variable a results in the numeric value 3, which is a bit combination of 1 for 'a' and 2 for 'b'.

      Commas should be disallowed in values for SP SET variables.
