There is simpliest way to found non numeric symbols in string:
.....
if patindex('%[^0-9]%',@s)>0
set @value=0
....

For character type strings you expect to be integers, there's also

ISNUMERIC(RTRIM(@value) + '.0e0')

I think everyone is totally missing the point that the IsNumeric function succeeds on junk that will fail when you later do a cast. Do your suggestions handle the strange cases in the comments at the top of my IsBigInt function?
