Hi Scott,

While the revdb_querylist() function will return a
tab-and-return- delimited list of the results of your
query, you can also use the revdb_query() function.
This returns a database cursor ID, which you can use
in the revdb_movefirst(), revdb_movenext(),
revdb_columnbyname() and some other functions and
names.
So if you want to display the contents of the colulns
of your first record of the query result in a couple
of fields, you can use something like:
--
  put "SELECT * FROM users" into tSQL
  --> EXECUTE SQL
  put revdb_query(,,gConID,tSQL) into tCursorID
  --> EXTRACT SOME FIELDS FROM THE FIRST RECORD IN THE
CURSOR
  put revdb_columnbyname(tCursorID,"edName") \
      into field "edName"
  put revdb_columnbyname(tCursorID,"edEmail") \
      into field "edEmail"
  put revdb_columnbyname(tCursorID,"edSubscribed") \
      into field "edSubscribed"
  --> DON'T FORGET TO CLOSE THE CURSOR WHEN YOU'RE
DONE
  get revdb_closecursor(tCursorID)
--

Hope this helped,

Jan Schenkel.
