Problembeschreibung: | |
DB2 might produce incorrect results when running queries with equality timestamp predicates Description: Under rare scenarios, DB2 might produce incorrect results if the following conditions are true: 1) The query contains two or more subselects and tables 2) Each of these have atleast one column of type TIMESTAMP with default precision 6 3) One or more of these columns are projected out from the select 4) The columns also contains an equality predicate with a string representation of timestamp eg. Select * from T1, (Select TS from T2 where T2.TS = '2015-01-01 00:00:00') as tmp where T1.TS = '2015-01-01 00:00:00' and tmp.TS = '2015-01-01 00:00:00' | |
