SQL学习—INSERT、UPDATE、DELETE语句

SQL之INSERT、UPDATE、DELETE总结

一、数据插入

INSERT INTO Cusomers
VALUES('100006','Toy Land','123 Any Street','New York','NY','1111',NULL,NULL);

INSERT INTO Cusomers (cust_id,cust_name,cust_address,cust_city,cust_state,cust_zip,cust_contact,cust_email)
VALUES('100006','Toy Land','123 Any Street','New York','NY','1111',NULL,NULL);

INSERT INTO Cusomers (cust_id,cust_name,cust_address,cust_city,cust_state,cust_zip)
VALUES('100006','Toy Land','123 Any Street','New York','NY','1111')

INSERT INTO Cusomers (cust_id,cust_name,cust_address,cust_city,cust_state,cust_zip)
SELECT cust_id,cust_name,cust_address,cust_city,cust_state,cust_zip FROM CustNew

SELECT * INTO CustCopy FROM Customers

二、更新数据

UPDATE Customers
SET cust_contact='Sam Reberts',cust_email='sam@toyland.com' WHERE cust_id='1000006'

三、删除数据

DELET FROM Customers WHERE cust_id='1000006'
