Is there an easy way to get if string is an integer number (consists only of digits) in MS SQL 2005?

Thank you for your help.

    Even though the original poster was referring to SQL 2005, I found in 2008 r2 a straight where isnumeric(string) resulted in an error 4145 non-boolean type. To resolve this use:where isnumeric(string) = 1
