4gl, cursor and count
Frank Fischer asked how to count the rows in a 4GL cursor. Robert Vorbroker thought a value in the SQLCA record might help after opening. Surfer! said that is unreliable, since without a temp table the rows are simply sent until done. Paulo Matheus said sqlca.sqlerrd[2] or DBINFO gives rows processed for select, delete or update. No confirmation from Frank.

Hello, i have a cursor and i want to now how many records are inside this. I don't now the syntax and I couldn't find something in the handbooks. Can anyone help me? Please excuse my english. -- cu Frank Fischer
OK my memory is a bit foggy on this one but once you have opened the cursor can't you check one of the values of SQLCA record to see how many rows were selected. Can someone flesh out my memory???...I'm having sometimers disease... OPEN cursor_name Let l_num_rows = SQLCA. something... Obnoxio, Art, Someone???

Maybe, maybe not. AFAIK if the SQL behind the cursor doesn't need a temp table to produce the results (no ORDER BY on a single table query) it will just keep sending the rows back until there are no more to send. > >Rob Vorbroker >Frank Fischer <FischerF@lsv-gartenbau.de> wrote in message >news:39D0A8DD.D7492DEB@lsv-gartenbau.de... >> Hello, >> i have a cursor and i want to now how many records are inside this. >> I don't now the syntax and I couldn't find something in the handbooks. >> Can anyone help me? >> Please excuse my english. >> -- >> >> cu >> Frank Fischer > > -- Surfer!
The number of rows processed (in select, or delete, or update) can be obtained using in the sqlca.sqlerrd[2] into a variable within the application. Or you can use the DBINFO function, as above: let v_variable = dbinfo(`sqlca.sqlerrd2`) Hope this helps.
