    SQL language change in 11g?

      Is anyone aware of any changes to SQL language with Oracle 11g, from 10g? We have recently upgraded a database from 10g to 11g. A Microsoft Access database we are using has a large amount of SQL pass-thru queries, and we are having trouble with it now, since the Oracle database has been upgraded to 11g, particularly with "Invalid Use of Null" error message, though no code has been changed. We have also upgraded our Oracle client to the 11g Full-client, and changed the driver name in the scripts to reflect this. We've had luck connecting to the 11g database in other manners (i.e., import external data > ODBC sources).

          Could you please provide some example of the issue you are facing?

            The VBA script, within Microsoft Access 2007, runs up to this SQL script, though strangely even if I comment out the "Is Null" statements:

            strSQL = "SELECT DISTINCT IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"") AS AQ_CODE, qsptLOCATION.AQUIFER_CODE, qsptLOCATION.LOC_CODE, qsptLOCATION.CLASS, IIf([tblWellInfo]![CP_TBL_V]=""POC"",""Compliance"",IIf([tblWellInfo]![CP_TBL_V]=""POE"",""Exposure"","""")) AS DESIGNATION, IIf(clng(tblWellInfo.SEG_SCR) > 1,""M"","""") AS MULTI_LEVEL, tblWellInfo.PROPERTY INTO tbl_LOCATION " & _
            "FROM qsptLOCATION INNER JOIN tblWellInfo ON qsptLOCATION.LOC_CODE = tblWellInfo.WELL_ID " & _
            "WHERE (((IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"")) Like 'PER*' Or (IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"")) Like 'OGA*') " & _
            "AND ((qsptLOCATION.LOC_CODE) Not Like '*-F' And (qsptLOCATION.LOC_CODE) Not Like 'FPOP*' And (qsptLOCATION.LOC_CODE) Not Like 'OSO*' And (qsptLOCATION.LOC_CODE) Not Like '*GAL') " & _
            "AND ((qsptLOCATION.CLASS) Is Null) AND ((qsptLOCATION.DESCRIPT) Is Null)) OR (((IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"")) Like 'PER*' " & _
            "Or (IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"")) Like 'OGA*') " & _
            "AND ((qsptLOCATION.LOC_CODE) Not Like '*-F' And (qsptLOCATION.LOC_CODE) Not Like 'FPOP*' And (qsptLOCATION.LOC_CODE) Not Like 'OSO*' And (qsptLOCATION.LOC_CODE) Not Like '*GAL') " & _
            "AND ((qsptLOCATION.CLASS) Is Null) AND ((qsptLOCATION.DESCRIPT) Not Like '*RENAMED*')) " & _
            "OR (((IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"")) Like 'PER*' Or (IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"")) Like 'OGA*') " & _

            "(IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala"")) Like 'OGA*') " & _
            "AND ((qsptLOCATION.LOC_CODE) Not Like '*-F' And (qsptLOCATION.LOC_CODE) Not Like 'FPOP*' And (qsptLOCATION.LOC_CODE) Not Like 'OSO*' And (qsptLOCATION.LOC_CODE) Not Like '*GAL') " & _
            "AND ((qsptLOCATION.CLASS) Not In ('PR','AW','IB','PV','IJ')) AND ((qsptLOCATION.DESCRIPT) Not Like '*RENAMED*')) " & _
            "ORDER BY IIf(qsptLOCATION.AQUIFER_CODE Like 'PER*',""Perched"",""Ogallala""), qsptLOCATION.LOC_CODE;"

                We removed "DISTINCT" from the beginning of the script, which solved the problem. But now we are having other problems with the Access database / SQL pass-through queries. Is there much that has changed with Oracle 11g that the SQL queries must be written differently?
