Question : Something similar to VB's AndAlso / OrElse in SQL Server

Is there an operator in SQL Server that is similar to VB's AndAlso or OrElse?  Something where if the first condition is true, it stops evaulating the statement?

IF Object_ID('tempdb..#MyTemptable') IS NULL or (SELECT SUM(MyValue) FROM #MyTemptable) IS NULL

If #MyTempTable hasn't been created, this will fail with an error.  I've already coded around it, but I was wondering if there was such an operator in SQL?

Thanks,
Landy

Answer : Something similar to VB's AndAlso / OrElse in SQL Server

You have to evaluate both things separately:

IF NOT(Object_ID('tempdb..#MyTemptable') IS NULL )
BEGIN
  If NOT (SELECT SUM(MyValue) FROM #MyTemptable) IS NULL
  BEGIN
    -- do your stuff here...

  END
END
