My guess for this request is that alot of people would rather write: SELECT * FROM Table; instead of: SELECT column1, column5, column2, column3, column4 from Table; I've seen alot of "BEST PRACTICE" advice on this list that suggests that writing out all of the columns is recommended. However, I am sure that there are alot of individuals that like to write these queries with the least amount of code possible. Regards, Richard Broersma Jr.
