數據庫SQL實戰 --42.將id=5以及emp_no=10001的行數據替換成id=5以及emp_no=10005

題目描述

將id=5以及emp_no=10001的行數據替換成id=5以及emp_no=10005,其他數據保持不變，使用replace實現。
CREATE TABLE IF NOT EXISTS titles_test (
id int(11) not null primary key,
emp_no int(11) NOT NULL,
title varchar(50) NOT NULL,
from_date date NOT NULL,
to_date date DEFAULT NULL);

insert into titles_test values ('1', '10001', 'Senior Engineer', '1986-06-26', '9999-01-01'),
('2', '10002', 'Staff', '1996-08-03', '9999-01-01'),
('3', '10003', 'Senior Engineer', '1995-12-03', '9999-01-01'),
('4', '10004', 'Senior Engineer', '1995-12-03', '9999-01-01'),
('5', '10001', 'Senior Engineer', '1986-06-26', '9999-01-01'),
('6', '10002', 'Staff', '1996-08-03', '9999-01-01'),
('7', '10003', 'Senior Engineer', '1995-12-03', '9999-01-01');

解決思路

REPLACE INTO titles_test VALUES (5,10005,'Senior Engineer','1986-06-26','9999-01-01')
