Dear PATSTAT user, Thanks you for your precise question. However, I doubt that your query ever worked. The error "Invalid column name 'ipc_subclass' " is in the GROUP BY clause. The attribute "ipc-subclass" does not exist in the database. It is just defined in the SELECT clause as an alias for "LEFT...

In case another download format (CSV, Excel .xlsx, MS Access .accdb) would also work for you, then please note that there are several other download options available ("Download result ...
