执行此操作:
CREATE TRIGGER `after_order_insert`
AFTER INSERT ON `hb_orders` FOR EACH ROW
BEGIN
UPDATE hb_accounts
SET hb_accounts.domain = (SELECT companyname FROM hb_client_details
WHERE hb_client_details.id = NEW.client_id
LIMIT 1)
WHERE hb_accounts.client_id = NEW.client_id;
END
结果如下:
/ * SQL错误(1064):您的SQL语法有错误;检查与MySQL服务器版本对应的手册,以便在第8行* /
附近使用正确的语法我错过了什么?这应该有用,不应该吗?

您最有可能尝试在不更改分隔符的情况下添加触发器。由于触发器包含分号,因此您必须暂时将分隔符更改为其他内容;
DELIMITER //
CREATE TRIGGER `after_order_insert`
AFTER INSERT ON `hb_orders` FOR EACH ROW
BEGIN
UPDATE hb_accounts
SET hb_accounts.domain = (SELECT companyname FROM hb_client_details
WHERE hb_client_details.id = NEW.client_id
LIMIT 1)
WHERE hb_accounts.client_id = NEW.client_id;
END //
DELIMITER ;
An SQLfiddle with the trigger adding successfully。请注意,分隔符在设置中更改

这是另一个实现:
CREATE TRIGGER `after_order_insert`
AFTER INSERT ON `hb_orders` FOR EACH ROW
UPDATE hb_accounts a
join hb_client_details b on a.client_id = b.id and b.id = new.client_id
set a.domain = b.companyname;
