Invalid column name on sql server update after column create

Question

Does anyone see what\'s wrong with this code for SQL Server?

IF NOT EXISTS(SELECT *
              FROM   sys.columns
              WHERE  Name = \'OPT_LOCK\'         


        

Answer 1

The root cause of the error is the newly added column name is not reflected in the sys.syscolumns and sys.columns table until you restart SQL Server Management Studio.
