Paul,
I don't know of any tools offhand. T-SQL is quite different that Jet's SQL.
The wildcard character is different (%, *), functions are different (Convert,
GetDate(), CharIndex, ...), and T-SQL can take advantage of things like
nested Selects (which Jet hates).
You can use the Query Analyzer, paste in the old Access queries, and modify
each query pretty easily.
Just some thoughts,
Wayne
