Question

I have one combo box having names of all the tables. Inside one procedure i want to get the value from combo box(ie the name of the table) and want to create temp table for that dynamically .. Need help on this please..

Answer 1

Given that you have a handle to your ComboBox-Widget, you can create a new temp-table dynamically like this:

DEF VAR ttH AS HANDLE.
CREATE TEMP-TABLE ttH.
ttH:CREATE-LIKE(ComboBoxWidgetHandle:SCREEN-VALUE).

This now takes the ScreenValue of the ComboBox Widget and uses the CREATE-LIKE method of the TempTable Object handle to create a TempTable with the exactly same fields as the table in the database. This only works if ComboBoxWidgetHandle:SCREEN-VALUE is exactly the same as a table name in the database, for instance 'Customer' in the SportsDB.
