parser greedily parses AS OF TIMESTAMP

    XMLWordPrintable

Details

    Description

      In AS OF TIMESTAMP xxx, the TIMESTAMP is always parsed as a part of AS OF, even if it's actually a part of the expression (the complete expression being TIMESTAMP xxx).

      Examples:

      DATETIME literal

      		 
      SELECT TIMESTAMP'2016-02-30 08:07:06';
      		 
      → ERROR 1525 (HY000): Incorrect DATETIME value: '2016-02-30 08:07:06'
      		 
      SELECT * FROM t1 FOR SYSTEM_TIME AS OF TIMESTAMP'2016-02-30 08:07:06';
      		 
      → ok
      		 
      SELECT * FROM t1 FOR SYSTEM_TIME AS OF (TIMESTAMP'2016-02-30 08:07:06');
      		 
      → ERROR 1525 (HY000): Incorrect DATETIME value: '2016-02-30 08:07:06'

      two-argument TIMESTAMP() function

      		 
      SELECT TIMESTAMP('2003-12-31 12:00:00','12:00:00');
      		 
      → ok
      		 
      SELECT * FROM t1 FOR SYSTEM_TIME AS OF TIMESTAMP('2003-12-31 12:00:00','12:00:00')
      		 
      → ERROR 1241 (21000): Operand should contain 1 column(s)
      		 
      SELECT * FROM t1 FOR SYSTEM_TIME AS OF (TIMESTAMP('2003-12-31 12:00:00','12:00:00'));
      		 
      → ok
