Progress Query Types

The DataServer provides several ways to submit a Progress query to an ODBC data source:

Whether your application can take advantage of the strengths of a particular approach depends on the kind of query you are writing and the kind of data you are accessing. Another factor to keep in mind when you decide which technique to use for issuing queries is whether a query is better served by being processed by the client or by the server. Progress 4GL queries are processed by the client (except in the cases of most joins); SQL SELECT statements and vendor-specific SQL extensions are processed by the server (the ODBC data-source manager).
