Software vb.net & sql server 2005.

How do I go about splitting a large dataset into 2 datasets using one sqlserver database.

The existing dataset is too large and it is difficult to add columns to tables.

Thanks!

What do you mean by "too large"?  Too many rows, or too many columns?

93 tables - several tables have a large number of rows.

Rather than creating a single, all-encompassing Dataset, how about creating more targetted datasets - say per form, or per application area.  Would something along those lines fit?

Yes that should work, the application is almost finished.

Can I use the same sql server 2005 database for more than one dataset?

Actually, If I only move one area that would free up the the main dataset so it can be used.

>>Can I use the same sql server 2005 database for more than one dataset? <<  Yes, what gave you the idea that you couldn't?

A Dataset is composed to DataTables.  You can have as many Datasets as your application design requires.  There is nothing that requires a single dataset to describe an entire database.  A Dataset can be thought of as an "in-memory mini-database"  That does not mean that the Dataset is an in-memory version of the entire database.
