Thanks for the help and advice, however I will need to pull all of the data eventually as I will be moving the data from one database to another when completed. I just wanted to allow the user to view sample data to aid in deciding how to transfer the data. The new system has fields with different names...

On a slightly different note: Is it possible to do use tableupdate and table revert commands with sql passthrough... I cannot set up remote views on the data as, it doesn't work properly, whereas sql passthrough gets the data...

My experience with sql passthrough has always been of the reqad only variety and I have never had to update data before..

Thanks for all of your help... I'll go read that FAQ now...
Mike
