Set IDENTITY_INSERT ON is not working

Question

You might be just missing the column list, as the message says

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON

INSERT INTO [MyDB].[dbo].[Equipment]
            (COL1,
             COL2)
SELECT COL1,
       COL2
FROM   [MyDBQA].[dbo].[Equipment]

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF 

The relevant part of the error message is

...when a column list is used...

You are not using a column list, you are using SELECT *. Use a column list instead:

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON 

INSERT INTO [MyDB].[dbo].[Equipment] (Col1, Col2, ...)
SELECT Col1, Col2, ... FROM [MyDBQA].[dbo].[Equipment] 

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF 

In VB code, when trying to submit an INSERT query, you must submit a double query in the same 'executenonquery' like this:

sqlQuery = "SET IDENTITY_INSERT dbo.TheTable ON; INSERT INTO dbo.TheTable (Col1, COl2) VALUES (Val1, Val2); SET IDENTITY_INSERT dbo.TheTable OFF;"

I used a ; separator instead of a GO.

Works for me. Late but efficient!

Here's Microsoft's write up on using SET IDENTITY_INSERT, which might be helpful to others seeing this post if they, like me, found this post when trying to recreate deleted records while maintaining the original identity column value.
