union parser cleanup

Details

    • Task
    • Status: Closed (View Workflow)
    • Minor
    • Resolution: Fixed
    • 10.2.2
    • Parser
    • None
    • 10.2.1-1, 10.2.1-3, 10.2.1-4, 10.2.1-5

    Description

      This is a spin-off from MDEV-8380. The corresponding parser changes are too big to go into 10.1

      This task will remove a few "Incorrect usage of ... and ..." errors and will return "syntax error" instead.

      Example#1:

      SELECT * FROM t1 LIMIT 1 UNION SELECT * FROM t1 LIMIT 1;


      ERROR 1221 (HY000): Incorrect usage of UNION and LIMIT

      Example#2:

      SELECT * FROM (SELECT * FROM t1 PROCEDURE ANALYSE());


      ERROR 1221 (HY000): Incorrect usage of PROCEDURE and subquery

      Example#3:

      SELECT * FROM t1 NATURAL JOIN (SELECT * FROM t2 PROCEDURE ANALYSE());


      ERROR 1221 (HY000): Incorrect usage of PROCEDURE and subquery

      Example#4

      SELECT (SELECT 1 FROM t1 PROCEDURE ANALYSE()) FROM t2;


      ERROR 1221 (HY000): Incorrect usage of PROCEDURE and subquery
