I am trying to update a tables rn_descriptor field using columns defined in the same table (see below).

I get "The data types binary and varchar are incompatible in the boolean AND operator." when I run the update statement.

Data_Cert_Template_Id, product_id, service_id are binary fields.
Check_Area is text.

Can anyone help me out with the correct syntaxt?

Thanks

begin transaction
update Data_Cert_Template
set rn_descriptor = Data_Cert_Template_Id & ' - ' & Product_Id & '/' & Service_Id & ' ' & Check_Area

convert them to varchar when you are trying to append them together.

Got it to work.....

begin transaction
update Data_Cert_Template
set rn_descriptor = cast(cast(Data_Cert_Template_Id as int) as varchar) + ' - ' + cast(cast(Product_Id as int) as varchar) +
+ '/' + cast(cast(Service_Id as int) as varchar) + ' ' + Check_Area
--rollback
--commit

not sure why you would do a double cast. Why not just once as varchar?
