WRONG RESULTS FOR SQL ANSI JOIN QUERY POSSIBLE WHEN IFX_FOLDVIEW IS ACTIVE | |
Produkt: | |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 | |
Problembeschreibung: | |
You may observe wrong results when IFX_FOLDVIEW is active (set to 1 in the onconfig file). In the reported situation we have a CASE expression within the view that is being referenced in the SELECT statement. Depending on the query path chosen then an excess row was observed which does not match the filter. The SELECT statement is using ANSI JOIN and has predicate filters. | |
