Get DDL statements for Objects in Oracle

Advanced SQL IDEs such as TOAD, SQL Developer provide ways to view DDL statements for objects. There is another way you can accomplish the task using GET_DDL method defined in DBMS_METADATA package. See usage below.


Usage : dbms_metadata.get_ddl('Object Type','Object Name','Owner')

SELECT dbms_metadata.get_ddl('FUNCTION','GEN_NUMBERS','SUSIL') FROM dual;

Output:

CREATE OR REPLACE
FUNCTION "SUSIL"."GEN_NUMBERS"(
n IN NUMBER DEFAULT NULL)
RETURN array PIPELINED
AS
BEGIN
FOR i IN 1 .. NVL(n,999999999)
LOOP
pipe row(i);
END LOOP;
RETURN;
END;



SELECT dbms_metadata.get_ddl('TABLE','EMP','SUSIL') FROM dual;

Output:

CREATE TABLE "SUSIL"."EMP"
(
"ENAME" VARCHAR2(10),
"SAL" NUMBER(7,2)
)
PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING STORAGE
(
INITIAL 131072 NEXT 131072 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT
)
TABLESPACE "USER_TS" ;


Note : You cannot view the output if the code is wrapped up.

How to remove duplicate rows without using DISTINCT or ROWID or GROUP BY methods in Oracle?

Make use of SET operators and CTAS (Create Table AS) method.. Example: Create table tmp_tb1 as Select * from table1 intersect Select * from table1; truncate table table1; insert into table1 select * from tmp_tb1; -- This will now have removed all duplicates in the table... commit; *** You can use UNION operator in place of INTERSECT
