How to get DDL in Oracle

We can get the DDL of an object using GET_DDL()

It is a function of metadata package DBMS_METADATA.

Syntax:
select DBMS_METADATA.GET_DDL(‘TABLE’,'<table_name>’) from DUAL;

Example:

MUDHALVAN@UPGR:SQL> set long 1000
MUDHALVAN@UPGR:SQL> set pagesize 0
MUDHALVAN@UPGR:SQL> select DBMS_METADATA.GET_DDL(‘TABLE’,’EMP’) from DUAL;

Output:

CREATE TABLE “MUDHALVAN”.”EMP”
( “ENO” NUMBER(10,0) NOT NULL ENABLE,
“ENAME” VARCHAR2(20),
“DOB” DATE,
CONSTRAINT “EMP_PK” PRIMARY KEY (“ENO”)
