Oracle Changing Database Objects
Oracle Database Tips by Donald Burleson


We are developing a large application base on PL/SQL. We often have to change DB-Objects (e.g. adding a new column to a Table-Object or grant/revoke some privileges from/to some DB-Objects). With DB-Objects, I mean things like tables, triggern, tablespaces, synonyms and so on...

The biggest trouble comes within every new release. To enhance our application we have to know about the latest state of all DB-Objects. To find it out, we have to run through the history of all PL/SQL-Files.

There must be a better way to solve this problem. We wish something like "export all objects" could be run then we can get a lot of SQL-Files that contain the definitions of all objects. We could then take these files and put it into our new DB, so we have the latest state of the DB (without running through the history).

P.S. Sorry about my English.

This question posed on 18 November 2005


You can build a script that utilizes the dbms_metadata package to do this. Using this package you can capture the command to build any database object. Use a cursor from dba_objects to dynamically dump the SQL for the objects you are interested in.
