Extract DDL for MV

Question

I used this script to extract the DDL of a materialized view
select dbms_metadata.get_ddl('TABLE','PTC.NUM_CALL_MV') FROM DUAL;
I am getting the error below
object "PTC.NUM_CALL_MV" of type TABLE not found in schema "SYSTEM"
Where i am wrong?
Thankx

Answer 1

dbms_metadata.get_ddl('TABLE','PTC.NUM_CALL_MV') FROM
DUAL;Actually the problem is that get_ddl has argument schema. So if you want from another schema you supply it as third argument not <schema>.<object_name>
BTW MVs have their according tables as well so works both of them:
SQL> select dbms_metadata.get_ddl('TABLE', 'TEST_CNT') from dual;
DBMS_METADATA.GET_DDL('TABLE','TEST_CNT')
