use the cast or convert function on a varchar field
Posted on 2010-01-08
I have a varchar column in my table that contains commodity codes. Most of these codes are numeric and I want to find all records that have a commodity code between 2 and 99. I have tried to use the following statment:
Select * from sca
where cast(sca_commcode as bigint) between 2 and 99
This produced an error that stated error converting data type varchar to bigint.
After viewing the records, I see that some of the commodity codes are text entries such as 'Engine'
Is there a way to use cast or convert (or someother function) to return a value of zero if the value is a text entry? I guess what I am looking for is functionality similar to the VB val function.
