DROP TABLE tab01;
SELECT * FROM tab01;
CREATE TABLE tab01
(ID NUMBER NOT NULL PRIMARY KEY,
NAME VARCHAR2(50)
);
SELECT index_name,a.status FROM User_Indexes a
WHERE index_name IN ('SYS_C0098887','IDX_NAME');
ALTER TABLE tab01 MOVE;
INSERT INTO tab01
SELECT object_id,object_name FROM user_objects
WHERE object_id IS NOT NULL;
INSERT INTO tab01
SELECT 1,'a' FROM dual;
INSERT INTO tab01
SELECT 2,'b' FROM dual;
ALTER INDEX SYS_C0098885 REBUILD;
CREATE INDEX idx_name ON tab01(name);
SELECT * FROM tab01;
UPDATE tab01
SET NAME='aaaa'
WHERE NAME ='SRC_PROV';
Conclusion:
1,if primary key related index will impact dml operations
2,others indexes do not impact the dml operations.
