Techies,
I'm a DB2 newbie. I'm not quite used to the esoteric table names!;-) How do I get a data dictionary export from our dev instance--which-- I hope will provide a more verbose description of what these tables and attributes are trying to be.

Hi ditallop,

I'm not sure what you're trying to get to, but I'd start with a query of the sysibm.tables and/or sysibm.columns views.  They pull most of the table/column definitions into easy to use views.

you can also use the control center tool to see all tables, their columns etc

Kent,

Thanks for pointing me to the system catalogs. What I had in mind was more of a description of the purpose of the column. For example:

ENO               Employee Number
BDLOI            Building Location Identifier

rather than:

ENO             CHARACTER 20
BDLOI          NUMERIC

Ok.  :)

The view syscat.columns has a column named 'remarks'.  If a descriptive comment was generated for your column, it would be there.

one thing to note
it will only show remarks that people took the time to create using the comment on statement
you are not guaranteed to see something in the remarks column

 Well, for a brief moment I was hopeful.

Which version of DB2 are you using?  (What O/S is on the server?)
