我有一个很长的交易，我已经开始使用BEGIN，我在最后一行之前犯了大约 3 行的错误。有没有办法使那条线归零？
这是一个例子：
BEGIN TRANSACTION;
CREATE TABLE purchase(id integer PRIMARY KEY, purchasePrice integer CHECK(purchasePrice>0), customer text);
INSERT INTO purchase(purchasePrice, customer) VALUES(1200, "Jerome");
INSERT INTO purchase(purchasePrice, customer) VALUES(200, "Jeffery");
INSERT INTO purchase(purchasePrice, customer) VALUES(40, "Craig");
INSERT INTO purchase(purchasePrice, customer) VALUES(1640, "Donovan");
INSERT INTO purchase(purchasePrice, customer) VALUES(100, "Williams");
INSERT INTO purchase(purchasePrice, customer) VALUES(50, "Matsushi");
INSERT INTO purchase(purchasePrice, customer) VALUES(150, "Xhao");
INSERT INTO purchase(purchasePrice, customer) VALUES(250, "Dilberta");
INSERT INTO purchase(purchasePrice, customer) VALUES(840, "Brow"); //Supposed to be 9440,"Brown"
INSERT INTO purchase(purchasePrice, customer) VALUES(440, "DarkBrown");
INSERT INTO purchase(purchasePrice, customer) VALUES(20, "Black");
COMMIT;
我明白我可以稍后更新受影响的行。
另一个示例情况：
BEGIN TRANSACTION;
CREATE TABLE Movies(MId integer primary key autoincrement, Title text);
INSERT INTO Movies VALUES(1,'Capote');
INSERT INTO Movies VALUES(2,'Scent of a woman');
INSERT INTO Movies VALUES(3,'Stigmata');
INSERT INTO Movies VALUES(4,'Exorcist');
INSERT INTO Movies VALUES(5,'Hamsun');
//Changed my mind and want to name the table "movie" and name the columns "m_id" and "title".
所以，我想知道a）如何取消；b）是否有可能上升几行，如果可以，如何？
