Oracle: export procedures & triggers

Oracle Tips by Burleson Consulting

 

Question:  How can I export and import stored procedures, functions and trigger definitions?

 

Answer:  The Oracle export utility (exp or expdp) exports the data dictionary entities associated with an object, and a full export grabs the entire data dictionary.

 

You can also join dba_objects into the dba_source views to get the source for all stored procedures functions and triggers.  If you don't want to write your own dictionary scripts, get my Oracle script collection.

 

When using export, you can extract the trigger definitions by specifying the table name and using the rows=n option in the export parfile:

 

expdp fred/flintstone tables=(fred), rows=n

 

Displaying stored procedure, function and trigger syntax is trickier because the import utility (imp or impdp) does not display dictionary objects in a display format.  To display dictionary entries with import, include the rows=n and  show=y parameters.

 

impdp fred/flintstone tables=(fred), show=y, rows=n

 

You can also use the dbms_metadata procedure to extract DDL and stored procedure, function and trigger definitions.  The dbms_metadata utility is also used for punching source code, PL/SQL, and Java that is stored inside Oracle packages. Stored procedures or functions can also easily be extracted using dbms_metadata:

 

connect fred/flintstone;

spool procedures_punch.lst

select
   dbms_metadata.GET_DDL('PROCEDURE',u.object_name)
from
   user_objects u
where
   object_type = 'PROCEDURE';
 

spool off;
