Re: Oracle in system i termonology

DB2 Magazine, Quarter 2, 2002.

There was a comparison of basic commands and terminology from Oracle to DB2. Users, instances, databases, tablespaces, select, insert, etc. That's a good starting point. If you can't locate the article (say at a large city library's archives... <vbg>) then contact me offline and I will try to dig up the two pages I saved of the comparison and scan them and send them to you.

Also, the "bible" in Oracle land is the "Oracle xx The Complete Reference" (replacing xx with whatever the current version is). It's straight forward and actually comes close to being complete. Used to be published by Osborne. Have not used it since 8i, but should still be out there.

Ah OK -

As Charles said, the statement might also work in Oracle - but one must find the syntax - I have Oracle 10G on my PC - the free version. Took a quick look - not familiar enough yet with where to get the documentation.

Good luck on your job and take care.

Vern, I didn't explain sufficiently. I unfortunately could no longer find work in the I world so I have taken a more simple position that utilizes some skills i have with Crystal Reports and Business Objects however this is strictly an Oracle shop.

I am following this list strictly as an As/400 Anonymous type of thing. That may be the wrong term but you get my drift.

You have a couple nice options - you can create tables with data from another table, or combination of tables.

create table newlib/newtable as (select * from oldlib/oldtable) with data

You could even put that into a QM query with substitution variables for the table and library names, even other parameters from CPYF if you wanted, then put a command and CL program in front of that QM query.

The above statement works in V5R3, at least, I believe.

Thank you. One of the things I miss is the ability to quickly make test data. Something like the CPYF would be good.

Index = keyed logical
View = unkeyed logical with dropped fields, substringed fields, ect...
plus lots more you can do in an DDS logical.

One thing to understand, with RPG and record level access, you
explicitly open and use a keyed logical.

Whereas with SQL, on either the i or Oracle, you use the physical
table (PF) or view and behind the scenes the query engine may or may
not use the index.

HI I was wondering if there is someone in the group who knows both system i and Oracle and could then explain the basiscs to me in system i terms of the Oracle setup. I am not sure for example what is meant by indices or is this like a Logical file.

TIA,Adam
