Question

IN SQL Server there is a tasks feature and then you can ‘generate scripts’ which is useful for things like views and stored procedures, or more.

In Oracle, can I generate such a copy of Views? How is this done? I am using PL SQL.

I am trying to update my Oracle database on my laptop. REcently many new views and stored procedures were added to the database I am working on at job. I also work from laptop for development.

Rather than backup the entire database, if I can just copy these views and sp’s would be far easier.

Answer 1

It sounds like you are probably looking for the DBMS_METADATA package and the GET_xxx functions within that package. This is what tools like SQL Developer and other GUIs will call to generate the DDL for a particular object.

So, for example, if you wanted to get the DDL for the EMP table in the SCOTT schema in SQL (or PL/SQL), you can

SQL> ed
Wrote file afiedt.buf

  1  select dbms_metadata.get_ddl( 'TABLE', 'EMP', 'SCOTT' )
  2*   from dual
SQL> /

DBMS_METADATA.GET_DDL('TABLE','EMP','SCOTT')
