GLEN -- Not exactly. All of the data access methods for our default,
automatic datasource interaction can be overridden with
PL/SQL triggers. An example form that ships will all releases
of Forms 4.0 is called 'TTRIG.FMB' and shows off a normal
database block using an array in memory as the datasource,
rather than a query against Oracle. To have a normal database
block query its data from a flat file, a similar technique
would be used, only it would be userexit code which actually
does the external flat-file opens and reads.
Forms 4.0.13 on Windows will ship with a series of
demonstration user exits, together with instructions on how to
rebuild them, and how to use their functionality through a
friendly PL/SQL interface (also provided). Full text-file
open, read, append, close capabilies will be in there.
For Forms 4.5, the TOOLS_IO package will be supported as it is
presently in Oracle Graphics 2.0, which will add portable,
PL/SQL-driver flat-file access.
Hope this helps.
