I use Delphi. How could I create a virtual table on client side?

Thanks!

Do you mean something like a TMemoryDataSet?

The name seems right. I never saw it. All I need is a temperary table to store data and do a report. Then this table is not needed any more.
I know that VB6.0 is able to create one, but don't know Delphi 4.0.
If Delphi 4.0 can, I wonder whether it is much faster with temparary table than with a real table from database?

Thanks

There are various TMemoryDataSet components available. You could search the popular Delphi component sites to find the one that suits your requirements.

Performance depends on a lot of factors. The size of the table, the speed of your PC, Network, and Oracle Server, and of course the application logic that needs to query this table.
