Printing Reports Using DataWindows

Use Update( ) to save changes in a DataWindow control.
Update( ) generates SQL statements based on the contents of the primary, filter, and delete buffers.
You can control the WHERE clauses included in the SQL statements PowerBuilder generates.

A transaction is one or more SQL statements that form a logical unit of work.
Several PowerScript functions let you print the contents of a buffer and manage print jobs
