with exp/imp you can import/export a database, schemas, tables (+ indexes), but not functions/procedures separately.

Here are examples:

exp scott/tiger file=emp.dmp log=emp.log tables=emp rows=yes indexes=no
exp scott/tiger file=emp.dmp tables=(emp,dept)
imp scott/tiger file=emp.dmp full=yes
imp scott/tiger file=emp.dmp fromuser=scott touser=scott tables=dept

If you work with 10g or 11g (not for 9i), you can use impdp/expdp. See http://www.oracle-base.com/articles/10g/OracleDataPump10g.php

Thanks ppinon.   Can u give my syntax to transfer functions from one db1 to db2 ?

 

by: ppinonPosted on 2009-10-29 at 08:11:06ID: 25694534

You can exeute the following code on the db1, it will give you the full script for the user logged in. Then you copy/paste it to execute it on db2.

declare
    cursor c_f is select dbms_metadata.get_ddl('FUNCTION',u.object_name) scr from user_objects u where object_type = 'FUNCTION';
    v_script varchar2(32767) := '';
begin
    for r_f in c_f loop
        v_script := v_script || r_f.scr;
    end loop;
    dbms_output.put_line(v_script);
end;
/

1. create database link with system user, on destination db to source

CREATE DATABASE LINK TEST1
CONNECT TO SYSTEM
IDENTIFIED BY PWD
USING 'TEST1';

where TEST1 is tns entry in tnsnames.ora looking into source db.

2. on same server, use datapump utility with network link

impdp system network_link=TEST1 directory=DATA_PUMP_DIR SCHEMAS=schema_name logfile=1.log CONTENT=METADATA_ONLY

This will import all functions, procrdures, etc, without table data records
