Details

    • 10.2.4-1, 10.2.4-2

    Description

      These queries:

      SELECT 1 AS UNBOUNDED;
      		 
      SELECT 1 AS PRECEDING;
      		 
      SELECT 1 AS FOLLOWING;
      		 
      SELECT 1 AS TIES;
      		 
      SELECT 1 AS OTHERS;
      		 
      SELECT 1 FROM EXCLUDE;

      return a syntax error:

      ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'UNBOUNDED' at line 1

      This is wrong. According to the standard, these keywords must be non-reserved.

      All these queries worked fine in 10.1. So this is a regression.

      This query correctly fails:

      SELECT 1 FROM WINDOW;

      as WINDOW is a reserved keyword, according to the standard.
