SQL Server Database Problems

Question

I have been using SQL Server for sometime with my company's product with no
unusual problems for some time.
However, having recently installed a Forte repository on a newly setup NT
machine (Workstation 4, SP4), I have come across problems.
The code constructs a cusor which requests columns from a table. Some of those
columns are of int type but when they are retrieved, the values are completely
different to those that can be seen when writing SQL statements directly from
ISQL.
For example, 1 becomes a seven figure number.
The following code is being used to iterate through the result set and create
another string which is made from the values concatenated together :
for CurRow in 1 to outputDataSet.ActualRows do
outputDataSet.CurrentRow = CurRow;
for curCol in 1 to outputDataSet.ColumnList.Items do
outputDataSet.GetValue(curCol,Value);
if(not Value.IsNull) then
// If datetime datatype, need some conversion
if (outputDataset.columnList[curCol].DataType =
DV_DT_DATETIME ) or (outputDataset.columnList[curCol].DataType =
DV_DT_DATETIME_NULLABLE ) then
begin
tempDateTime.SetValue( Value.TextValue );
-- The user has entered an invalid Date format.
exception
when e : UsageException do
tempDateTime.DecodeValue(source=Value.TextValue,
format=dateForm);
end;
pResultData.Concat(dateForm.FormatDate(tempDateTime));
else
pResultData.Concat(Value.TextValue);
end if;
end if;
if(curCol <> outputDataSet.ColumnList.Items ) then
-- pResultData.Concat('\t');
pResultData.Concat(pDelimChar);
else
pResultData.Concat( source = '\r\n' );
end if;
end for;
end for;
This has not occurred on any other installation and the only ideas that I have
are that :
i) the ODBC driver is either the incorrect version or has been setup incorrectly
in some way
ii) there are problems with the configuration of SQL Server or NT that is
causing this problem
Does anyone have any ideas ?
Thanks,
Alex

My recomendation is to debug the web page. Set a breakpoint by clicking on the row say probably at the page load/form load event. Press F5 to start the debug. Click F10 to step over next row multiple times until and unless you get the error message. i.e
Invalid column name 'UserId'.
The piece of code which you have posted does not contain any assignment or usage of column name "UserId", therefore post the portion of the code where the error is actually taking place.
