Should i rs.close and Set rs = Nothing in each loop?
Hi,
The code below simply creates a fixed-field string from the data in a database.
It reads a list of item codes from another file for the where clause of the query.
Question:
Should I close the recordset and set it to nothing before re-setting the query with the new where clause?
It doesn't seem to matter whether I do or don't.
Thanks,
Al.
Code:
Open "d:\focus\itemcode.prn" For Input As #1
While Not EOF(1)
Line Input #1, ItemCode
Set rs = cn.Execute("Select t$item,t$desc,t$cost,t$whse,t$quan " _
& "from tiitm001 where t$item='" & ItemCode & "'")
Do Until rs.EOF = True
FocusString = Space(80)
Mid(FocusString, 1, 20) = rs.Fields(0).Value
Mid(FocusString, 21, 30) = rs.Fields(1).Value
Mid(FocusString, 51, 10) = rs.Fields(2).Value
Mid(FocusString, 61, 10) = rs.Fields(3).Value
Mid(FocusString, 71, 10) = rs.Fields(4).Value
Print #2, FocusString
rs.MoveNext
Loop
' **************************************
' Do I need the following 2 lines for each iteration of the While/Wend loop?
rs.Close
Set rs = Nothing
' **************************************
Wend
cn.Close
Close #1
Close #2
Set rs = Nothing
Set cn = Nothing

You should close before executing another command, but you don't need to set the recordset to nothing until you've completely finished using it.

I'd set it to nothing each time, because you're generating new recordsets with the cn.execute rather than re-using the same recordset object. I'd personally modify the code to use rs.Open for each query, that way you're using the same object.
