Delete query object if it exists

Hi

I have some Mail Merge code which works fine, but when I go to run it again, it recognises the query object previously created & errors err no 3012 - object already exists.

I want to know how to have the error handler delete the query although sometimes the query would not have been created yet.

So first time I use it, the query isn't an object in the db & so no problem. The second time the query does exist & I get the error.

If I try to add code to delete the query before it's created, I naturally get an error because there's no such object.

Hope that explains it clearly, here's my code, Thanks

--------------------------------------------------------------------Option Explicit
Sub mail_merge(print_records_where As String)

Dim qdftemp As QueryDef
Dim QueryDef As Recordset
Dim mail_merge As QueryDef
Dim rst As Recordset

Dim cn As ADODB.Connection
Dim maindoc As Word.Document
Dim sdbpath As String

'Initialisations
Set cn = CurrentProject.Connection
Set db = CurrentDb()

If print_records_where = "" Then

print_records_where = " org_id = 0"

End If

'Note print_records_where uses the results of a search function

Set rst = qdftemp.OpenRecordset

rst.CopyQueryDef

If rst.RecordCount = 0 Then

MsgBox "There are no Records for your criteria, Try again", vbOKCancel, "No Matches"
'GoTo NoRecords

End If

DoCmd.OpenQuery "mail_merge", acViewNormal, acPreview

If MsgBox("Send Letters to these Recipients?", vbYesNo, "Mail Merge?") = vbYes Then

Set wordapp = New Word.Application
Set maindoc = wordapp.Documents.Open("C:\Documents and Settings\letter2.docx")
wordapp.Visible = True
With maindoc.MailMerge
.MainDocumentType = wdFormLetters

End With

.MailMerge.Execute
End With
wordapp.Activate
wordapp.Documents.Parent.Visible = True
wordapp.Application.WindowState = 1
wordapp.ActiveWindow.WindowState = 1

Else: GoTo NoRecords

End If

DoCmd.Close acQuery, "mail_merge"
db.QueryDefs.Delete qdftemp.Name

End Sub

Thanks

noboffinme,

Can you please put your code in code tags so it's more readable.

OK, is this what you mean?

Here's the answer if anyone needs it, Cheers

Add this function to a module

Instead of creating and deleting querydefs, qhat you need to do is create the mail_merge query as a blank query, i.e. it should just have SELECT;

Then anytime you want to use the query, simply change its SQL like this:

Thanks vbaInet for the tip about the

Code:

 option.
[[COLOR=Red]\[/COLOR]code]
 [/QUOTE]No problem but you've got the closing tag wrong. it's with a backslash, i.e. [COLOR=Blue]/[/COLOR] not a[COLOR=Red] \[/COLOR]

Great, Thanks again
