Mysql写sql表别名

1、insert语句

INSERT INTO cold_address_character AS a (a.applyerId) VALUES (235);
执行错误
不用别名
INSERT INTO cold_address_character ( applyerId) VALUES (235);
执行正确

2、update语句
取别名
UPDATE cold_address_character AS a SET a.applyerId = ‘2’ WHERE a.applyerId = ‘1’;
执行正确

3、delete语句
DELETE FROM cold_address_character a WHERE a.id = 1
执行错误
DELETE FROM cold_address_character WHERE id = 1
执行正确
