Recently, we have had several SQLServer boxes move to SQLServer 6.5 sp4. At the same time, new odbc drivers were added. We have an application that needs to create indexes on several tables. If we end up with duplicates in the table we have relied on odbc to come back with something other than SQL_Success. This worked fine until the recent upgrade. Now, we get no error message when the create index fails on a dup row senario. We get SQL_Success from ODBC. Anyone seen this before?
