Connecting to a Data Source

Now that we had a quick tour of the DataWindow painter, let's return to the creation of a DataWindow. One of the fundamental objectives of a DataWindow is the collection of information from a database. The method by which it performs this task is complex and worth investigation.

SQL Select

External
Stored Procedure
