How do I know how many entries were retrieved?

Hi,


  I'm relatively new to Oracle and have a pretty simple question.  I have
a hypercard stack interface to Oracle and I want to display a message 
saying "No entries retrieved" after appropriate queries.  I have the
queries return their responses directly to the screen, but if no entries
are retrieved, I don't want to blank out the results of the previous 
query (which is what happens when no entries are retrieved).  I could send
the query results to invisible fields, and then copy the fields, but this
might take too long.  I'm hoping that there's a more elegant way to do this.
  Any ideas will be appreciated,


     Dave.
