Connection string portability In some circumstances, we might need to create several QVW files for extracting several tables from a particular database. An elegant and administration-friendly approach is to store the connection string in a text file, residing in a folder that is reachable from your QVW files. Import this connection into every QVW via an include statement (from the Edit Script window, select Insert | Include Statement). The benefit of this approach is that if the connection string should change, you only need to modify it in one place, and all of the corresponding QVW files will automatically use the updated Connect statement.
