| Dale writes "I have a text file that is being imported into a sql table periodically. The data is a mixture of text and numeric data so I store it in a varchar field. In my stored procedure, I query the field value and if it is numeric I need to cast it to a real value and use it in an arithmetic operation. Obviously, if it is text I can't do that, but I would like a way to know if the value is numeric before getting an error on the cast. I am looking for something like an IsNumeric() function in VB. Any ideas?Thanks." |

| I'd suggest the IsNumberic function in SQL Server. We don't have an article on it but Books Online has a good description. |
