On the AS/400, *SQLPKG is an object type.

Yes I know, an object type of the type *SQLPKG meaning SQL package, but what the ..... is an SQL package:
- Where are they come from
- What does it do
- How to create
- What can I do with it
- Why do I want to have a SQL Package

Shalom CarmelCTOCommented:
An object of type *SQLPKG is created and used when your application uses data from remote databases.

This object is placed on the remote system to manage the connection and the data exchange.

Note: It is not necessary to use SQL packages for a distributed application to work, but the are benefits...

Hmmm, a little poor info on that link.

Is there some example to find (I double the points)
Shalom CarmelCTOCommented:
Well, suppose you have 2 databases, let's put them on different servers.
You have an RPG (or any other supported language) program on systemA which should access the database on systemB.
You have 2 options:

A. In your SQLRPG program, use an explicit CONNECT statement, like this:
 CONNECT TO SYSTEMB USER murphey2 USING 'password'

and then run your SQL as usual, only now it will execute on systemB.

B. Write a regular SQLRPG program, but during compilation provide it with specific instructions to create a SQL package on the remote systemB:

This compilation will create a *PGM object on your systemA, and a *SQLPKG object on systemB.

At runtime, the local program will connect to the remote database via the SQL package for optimized results.
