  2. MCOL-4613

Garbage result of a union between huge narrow DECIMAL and BIGINT

Details

    • 2021-7

    Description

      This ticket is for 5.6.1 only. Testing in 6.1.1 will need to wait until MCOL-4612 is MERGED into develop branch

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(17,1), b BIGINT) ENGINE=ColumnStore;
      		 
      INSERT INTO t1 VALUES (9999999999999999.9, 999999999999999999);
      		 
      SELECT * FROM (SELECT a FROM t1 UNION SELECT b FROM t1) tu;

      | a                     |

      +-----------------------+

      Looks wrong.

      Note, the problem cannot be repeated in 6.x because of MCOL-4612
      But perhaps it still exists. MCOL-4612 needs to be fixed first to verify it further in 6.x.
