Using an Existing Database Application developers can create HP ALLBASE/4GL applications to access existing databases. To access existing tables, the developer can define select lists using HP ALLBASE/4GL field specification and column definitions as required. The developer can then use a SELECT command in an SQL logic block to access the required table. Refer to the HP ALLBASE/4GL Developer Reference Manual for more information about these facilities. Alternatively, the developer can define (but not create) a table using the developr file/SQL table definition screen. The HP ALLBASE/4GL definition of the table must have the same name as the existing table and use column names that match the columns of the existing table.
