Contains Characters or Numbers Method

Hello,

I was wondering if there is any method that I can use to determine if a field (defined as text) has any character fields or is really a number. I want to figure out if a field is truly all numeric, and out of curiosity, was wondering if there was a way in SQL or T-SQL.

Thanks.

look at SQL Server function IsNumeric. It return 1 if it is, otherwise 0. You can use it with CASE WHEN. If it is numeric, get it, otherwise, set to other value such as 0.

You can check whether the following will work for you:

WHEREyourColumnNOTLIKE'%[^0-9]%'

or

WHERE IsNumeric(yourColumn)=1

Hey,

I didn't know there was an IsNumeric method... and I'm using SQL 2000 so regular expression's won't work for me. Sorry I should have mentioned the 2000 part.

Thanks.
