Progress 4GL Handbook

Using Queries

The programming syntax you have learned so far uses blocks of 4GL code to define and iterate through a set of records. Progress defines an alternative to this form of data access called a query. You’ve seen queries in action already, in the chapter where you looked at the syntax the AppBuilder generates to define a default result set for a window and to display its records in a browse. This chapter discusses why these different forms exist and how you can use queries in ways that are distinct from how you would use a result set in a FOR EACH block. This chapter includes the following sections:
