Question : use the cast or convert function on a varchar field

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.

Answer : use the cast or convert function on a varchar field

please try this:

Select * from (
  select * from sca where isnumeric(sca_commcode) = 1
) sq
where cast(sca_commcode as bigint) between 2 and 99
