    Description

      A BETWEEN expression involving a VARBINARY column produces different results in a WHERE clause versus a SELECT list. The inconsistency appears to be caused by an incorrect type conversion rule.

      CREATE TABLE t238 ( c2 VARBINARY (47) UNIQUE);
      		 
      INSERT t238 () VALUES ('F');
      		 
       
      		 
      SELECT * FROM t238 WHERE ((c2) BETWEEN ('r') AND (1145));
      		 
      -- empty set
      		 
      SELECT SUM(count) FROM (SELECT ((c2) BETWEEN ('r') AND (1145)) IS TRUE AS count FROM t238) AS ta_norec;
      		 
      -- 1
