Question

I have this code, i’m trying to set the identity seed by a varable

DECLARE @iKeyX INT

SELECT @iKeyX = MAX(KeyX) FROM Temporales..tmp_Orders

IF (@iKeyX = NULL)
   SET @iKeyX = 1
ELSE
   SET @iKeyX = @iKeyX + 1

IF OBJECT_ID('tempdb..#tmp_Orders','U') IS NOT NULL
   DROP TABLE #tmp_Orders

SELECT  IDENTITY(INT, @iKeyX, 1) AS KeyX,
        0 AS Valido, 
        OrderNumber, 
        OrderType, 
        Code, 
        Size, 
INTO #tmp_Orders
FROM TableWithData

Why SQL keeps telling me “Incorrect syntax near ‘@ iKeyX'”?

Answer 1

This appears to be an old bug in SQL Server that has never been fixed. To work around the problem (as suggested in the link), build the command into a string and then execute the string.

Workaround from the link:

DECLARE @SQL varchar(8000)
DECLARE @myident int
SET @myident = 100
SET @sql = 'SELECT IDENTITY(INT, ' + CAST(@myident as varchar) + ', 1)    AS ident INTO #T2'
EXEC(@sql)
SELECT @@identity
