Access, IF EXISTS, error 3129

Hello.

Have some trouble with an SQL line.

If a user exists it should update PhoneEndDate, else insert a new record.

This works fine in SQL Analyzer:

IF EXISTS (SELECT * FROM tblTable1 WHERE UserID = 555555)
UPDATE tblTable1 SET PhoneEndDate = '13-11-2010' WHERE UserID = 555555
ELSE INSERT INTO tblTable1 (UserID , PhoneType, PhoneStartDate) VALUES (555555,1,'14-11-2010')

But when I put this en Access, I get runtime-error 3129:

SQLSelectUser = "IF EXISTS (SELECT * FROM tblTable1 WHERE UserID = " & sUserId & ") UPDATE tblTable1 SET PhoneEndDate = '" & sUserDate & "') WHERE UserID = " & sUserId & " ELSE INSERT INTO tblTable1 (UserID, PhoneType, PhoneStartDate) VALUES (" & sUserId & "," & sPhoneType & ",'" & sPhoneStartDate & "')"

Any idea why?



Thanks..

Are you running this in Access as VBA (in which case it will fail) or passing it to SQL Server (in which case you must uuse SQL Server syntax?

I dont think,you can use if exists.
ALTERNATE WAY IS RUN BOTH QUERY AS SHOWN BELOW.

UPDATE tblTable1 SET PhoneEndDate = '" & sUserDate & "') WHERE UserID = " & sUserId & "

INSERT INTO tblTable1 (UserID, PhoneType, PhoneStartDate)
SELECT " & sUserId & "," & sPhoneType & ",'" & sPhoneStartDate & "'
FROM tblTable1
WHERE UserID <> " & sUserId & "


IF THERE IS WAY THEN YOU WILL SURELY GET ANSWER,

The Access VBA ay would be:

IF DCount( "*", "tblTable1", "[UserID] = " & sUserId) = 0 Then
  SQLSelectUser = "INSERT INTO tblTable1 (UserID, PhoneType, PhoneStartDate) VALUES (" & sUserId & "," & sPhoneType & ",#" & sPhoneStartDate & "#)"
ELSE
   SQLSelectUser = "UPDATE tblTable1 SET PhoneEndDate = #" & sUserDate & "#) WHERE UserID = " & sUserId
END IF
Docmd.RUNSQL SQLSelectUser

Note dates must be enclosed in # in Access. Also watch the format you pass dates into Access - it may well try and "Americanise" them

Sorry for the long wait, but I've been away from work.

Thanks kelvinsparks.

A couple of issues with null though. But this is how it works now:
If DCount("*", "tblTable1", "[UserID]= '" & sUserId & "'") = 0 Then
    SQLSelectUser = "INSERT INTO tblTable1 (UserID, PhoneType, PhoneStartDate) VALUES (" & sUserId & "," & sPhoneType & ",'" & sPhoneStartDate & "')"
Else
    SQLSelectUser = "UPDATE tblTable1 SET PhoneEndDate='" & sUserDate & "' WHERE UserID= '" & sUserId & "'"
End If

DoCmd.RunSQL SQLSelectUser

Open in new window
