DBResultsToText

After retrieving a results record from DBGetQueryResults, you can use the DBResultsToText function to convert the returned data to text.

FUNCTION DBResultsToText (results: ResultsRecord; 
                          VAR theText: Handle): OSErr;

results

The results record returned by the DBGetQueryResults function.

theText
