Use the revMoveToPreviousRecord command to move around within the selected set of records.

Parameters:

The recordSetID is the number returned by the revQueryDatabase function when the record set was created.

Comments:

If the command could not move to the previous record because it's already at the first record or there are no records in the record set, the result function returns an error message that begins with the string "revdberr".

Note: Not all databases support the revMoveToPreviousRecordcommand. Currently the revMoveToPreviousRecord command is not supported by Oracle databases and certain ODBC data sources.

Important! The revMoveToPreviousRecordcommand is part of the Database library. To ensure that the command works in a standalone application, you must include this custom library when you create your standalone. In the Inclusions section of the General screen of the Standalone Application Settings window, make sure the "Database Support" checkbox is checked and the database drivers you are using are selected in the list of database drivers.
