not exactly =there are a few differences like Merge transformation can accept only two inputs whereas Union all can take more than two inputs. Also,data has to be sorted before using the Merge Transformation whereas Union all doesn't have that prerequisite------------------------------------------------------------------------------------------------------SQL Server MVPhttp://visakhm.blogspot.com/ |
