I have install nFeed and was able to create a custom field, which gets read by an SQL select query from the database. It works fine even with auto complete.
Now I would like to have another read only custom field, which displays anoter column of the same row. But I do not understand how to use an issue attribute in the SQL query.
How do I have to define such a read only field? Can anybody give me an example for the SQL query?
