@@ Identity从Access Frontend（SQL Server Express后端）返回0

Question

I have been all over the web looking for a way to fix this, and all the answers seem to tell me that I am doing this correctly. I have inherited this Access / SQL Server database, and I cannot seem to get this piece to work.

I am executing a fairly basic SQL INSERT query that works fine. I have checked it several times. Once the query executes, I am attempting to get the identity value back out of it to use for the rest of my code.

Here is my code:

db.Execute (SQLStr)

Set rs = db.OpenRecordset("SELECT @@IDENTITY")
InNo = rs(0)
Debug.Print InNo
rs.Close
db.Close

This always returns a value of 0 for InNo . I have tried several different methods but I cannot seem to get this working.

I have also used this method from the SQL Server directly, and querying the @@Identity works fine.

Thanks in advance.

I'm suspecting that you are running SELECT @@IDENTITY on your local Access database, which of course doesn't know what @@IDENTITY is.

I'm not 100% sure, though, because you didn't show your whole code and I don't know what db is.
If db is CurrentDB , then the Set rs = db.OpenRecordset line opens a DAO.Recordset which does execute the query on your local Access database.

If my suspicion is correct, then you need to open the recordset where you execute SELECT @@IDENTITY via pass-through query , so it actually runs on the SQL Server.
