A good question that has taught me two things:

1. You can't trust SQL's ISNUMERIC function
2. You can build a recursive CTE - although I'm no sure I would want to ;-)

If anyone else has examples of CTE's I bet they'd make for some tricky questions?

Thanks

2. You can build a recursive CTE - although I'm no sure I would want to ;-)

Recursive CTE'sare an invaluable tool when working with hierarchic data (like employee/supervisor relations, parts built of parts built of parts, genealogy data, etc). There are some examples of this in Books Online.

Very nice question. And one more time I see that 'isnumeric' works in a way which is far away from our expectations. Always used custom made functions instead.

Great question! Now that I know how "liberal" is numeric is, I will be more careful with it.
Thanks!!!
