Re: A quick EGL example

I can name that tune in ...

In a production setting the database is more than likely already established
or will be developed outside of RBDe. In that case, you will just connect to
the database and import the tables during your project setup. RBDe will then
automagically create the Control Records, Data Access Libraries, Data Access
Records and EGL Data Items for those tabels. This auto generation can
eliminate the need to manually code the records as Joe has illustrated. So,
after a one time setup, you can create Joe's example in... five minutes. :)

There are two pieces of code. One is the part that defines the records,
much like the DDS for externally described data structures:

package data;

Record OrderDetail type SQLRecord
OHCUST decimal(8);
OHSTATUS string;
OHORDER decimal(8);
OHAMOUNT decimal(11,2);
end

Record CategoryTotals type SQLRecord
Category String {column="Category"};
Total decimal(11,2) {column="Total"};
end

That defines two records, one for the list and one for the totals. And
you
can of course reuse those records over and over again in other
applications,
just the same as you would an EDS. The job of your program then is simply
to create arrays of that data. The EGL code to populate those totals:
