Hi pbd22,
Since those commented lines are *AFTER* the place where the error occurs
(the debugger jumps to the incorrect line; the only line that can cause
this error is either this one:
> SET ROWCOUNT @lbound
or this one:
> SET ROWCOUNT @perPage
I assume that it's the first, and that it's cause by some unexpected
things going on in the calculations neede to compute @lbound.
You already have added a great statement to aid in debugging; I'm gonna
ask you to add a bit more to it - so please change this:
> SELECT
>
> CurrentPage = @pagenum,
> TotalPages = @pages,
> TotalRows = @rows
to this:
SELECT
CurrentPage = @pagenum,
PageSize = @perpage,
TotalPages = @pages,
TotalRows = @rows,
UpperBoundary = @ubound,
LowerBoundary = @lbound
And then rerun the query and post back the results. We'll then have to
take it from there.
