Hi In my web page i have listbox in this i am getting the data from the datasource.so if the user selects 2 or 3 items in the list box how should i store that information into database.

what should i write for insert command for 2 or 3 items of selection

The simplest answer is to call one insert for each value. I don't believe that there is a way to insert more than one table row at a time. I think that you would find that even if you used a .NET dataset class and added many rows, that ultimately the underlying logic will also simply execute many individual inserts.
