      Receiving unexpected query results on the following query in MySQL 5.0:

      Query: SELECT BQT2.SmallA.IntNum, BQT2.MediumB.IntNum FROM BQT2.SmallA FULL OUTER JOIN BQT2.MediumB ON BQT2.SmallA.IntNum = BQT2.MediumB.IntNum ORDER BY BQT2.SmallA.IntNum, BQT2.MediumB.IntNum

      Database: jdbc:mysql://SLNTDS03.mm.atl2.redhat.com:3306/bqt2

      Driver: mysql-connector-java-5.1.5

      Expected results is 1007 records but MySQL is returning 1006. There are also some other issues.

      It appears (MediumB.IntNum = 26) is not being returned but it is expected and does exist in MediumB.IntNum. In addition one row is returning -21 when we expect -8 and many rows are returning "null" for MediumB.IntNum when we are expecting a value.

      I am attaching the log file, actual results file, expected results file, and the VDB.
