How do I convert an int column to a varchar in FrontBase SQL? I need to concatenate a varchar and an int field, and I cannot just concatenate them because both arguments need to be a varchar.
I wanted to tag this "Frontbase" but I don't have permission due to reputation < 1500.
Server and database version is 4.2.7
The query looks like this:
select (TVERKOPEN.CPREFIX || CAST(TVERKOPEN.CNUMMER AS VARCHAR)) as PurchaseOrder
from TVERKOPEN

Try with:
CAST(field AS VARCHAR(30))
