Question

这是我第一次尝试进行交易，并且我希望进行交易以从类表中删除所有德国船只，并同时在表格中添加新的美国船只。

START TRANSACTION
-- Delete Germany from classes table
DELETE FROM classes WHERE country = 'Germany';
-- Add new ship for USA into classes table
INSERT INTO `classes` (`class`,`type`,`country`,`numGuns`,`bore`,`displacement`) 
VALUES ('SS Farkas','bb','USA','10','20','36000');
-- Commit the transaction
commit;

我尝试在DELETE FROM语句的开头执行时遇到此语法错误：

语法错误：＆＃39;删除＆＃39; （删除）在此位置无效输入

Answer 1

您遗失;：

START TRANSACTION;

-- Delete Germany from classes table
DELETE FROM classes WHERE country = 'Germany';
-- Add new ship for USA into classes table
INSERT INTO `classes` (`class`,`type`,`country`,`numGuns`,`bore`,`displacement`) 
VALUES ('SS Farkas','bb','USA','10','20','36000');
-- Commit the transaction
commit;

Answer 2

删除查询有效，但您遗失了;。

START TRANSACTION应为START TRANSACTION;
