As you specify the data for the DataWindow object in the SQL Select painter, PowerBuilder generates a SQL SELECT statement. It is this SQL statement that will be sent to the DBMS when you retrieve data into the DataWindow object. You can look at the SQL as it is being generated while you continue defining the data for the DataWindow object.
To display the SQL statement:
Click the Syntax tab to make the Syntax view available, or select View>Syntax if the Syntax view is not currently displayed.
You may need to use the scroll bar to see all parts of the SQL SELECT statement. This statement is updated each time you make a change.
Instead of modifying the data source graphically, you can directly edit the SELECT statement in the SQL Select painter.
Converting from syntax to graphics
If the SQL statement contains
unions or the BETWEEN operator, it may not be possible
to convert the syntax back to graphics mode. In general, once you convert
the SQL statement to syntax,
you should maintain it in syntax mode.
To edit the SELECT statement:
Select Design>Convert to Syntax from the menu bar.
PowerBuilder displays the SELECT statement in a text window.
Edit the SELECT statement.
Do one of the following:
Select Design>Convert to Graphics from the menu bar to return to the SQL Select painter.
Click the Return button to return to the wizard if you are building a new DataWindow object, or to the DataWindow painter if you are modifying an existing DataWindow object.
