Thread: documenting tables version control

documenting tables version control

From
Suresh Raja
Date:
Hi All:

I have tables with different versions in the same schema.  Like 
T1a, T1b, T1c
T2a, T2b, T2c, T2d
....
...
etc.


I'm interested in documenting various version of tables, may be in excel sheet or may be in another schema in the database.  I would like to store information on table name, column names, column order, pry key column etc.  Also is there a way I can reverse engineer from the database itself.

Let me know if anybody any suggestion or format that they used.  I appreciate all your help and shall be suitably acknowledged. 

Thanks,
-Suresh Raja

This section of the documentation should tell you everything you
need to know:

Announcing "I'm offended" is basically telling the world you can't
control your own emotions, so everyone else should do it for you.

Try this query and see if it fulfills your needs. Adjust the WHERE clause as needed.

SELECT
       table_catalog as database,
       table_schema as schema,
       table_name as table,
       column_name as column,
       ordinal_position as position,
       column_default as default,
       is_nullable,
       data_type as type,
       character_maximum_length as max_length
   FROM information_schema.columns
 WHERE table_name LIKE 'T%'
ORDER BY table_catalog,
         table_schema,
         table_name,
         ordinal_position;

Thanks Melvin, Joshua, PT and Steve!

your information is good.  Im looking for creating a catalog for my application schema.  Do you have anything that you use for catalog of your schema.  Maybe using excel.

I just use sql tables. But if I represent them outside of pg I usually use migration files which are part of ruby on rails. But sqitch looks good too.

Yes Mercurial(mercurial.selenic.com) with Sqitch(sqitch.org). Then you
get a current catalog and a history of your catalog changes in Mercurial
and a way to go backwards and forwards in deploying those changes using
Sqitch.
