RE: How to chase down SQL0181 - Value in date, time, or timestamp string not valid.

The WHERE clause is evaluated before the columns in the filed list are calculated, i/e., before the result set is generated, and it is the result set that uses the alias. Therefore, the WHERE clause has to use the actual column names. You can make it work by using your expression instead of the alias.

But this is also why you CAN use the alias in the ORDER BY clause - the result set has been built by this time.

What gives?  And why when I try to test TranDate in a Where clause that it
spits out "Column TRANDATE not in specified tables"?

Man, I got a lot to learn about SQL.

Thanks,
