Hi all,
Is it possible to create views that take parameters? Basically, I have to create some very complex historical reports, and as of now I am using temporary tables to store intermediate query results. I calculate values based on the content of these temporary tables and use them in the final result. I would like to eliminate the need for temporary tables and use views instead, as the data copy between the temp tables is taking quite some time.
Thanks,
Kashmira

You can write a function (in SQL even) that would basically be a
parameterised view.
However, views don't "store" anything, so whether you see an improvement
in speed will depend on how long it takes to do your calculations.
