mysql - 为什么在MySQL 5 中运行脚本时start transaction 和rollback 无法回滚？

Question

我有以下脚本...

START TRANSACTION;

INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-114, NULL, NULL, 'c21_1.jpg', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-115, NULL, NULL, 'c21_2.jpg', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-116, NULL, NULL, 'c21_3.jpg', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-117, NULL, NULL, 'c21_4.gif', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-118, NULL, NULL, 'c21_5.gif', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-119, NULL, NULL, 'c21_6.gif', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-120, NULL, NULL, 'c21_7.gif', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-121, NULL, NULL, 'AIRMILES_MIN_RBLUE.png', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-122, NULL, NULL, 'c21_logo_commercial-WHT.png', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-123, NULL, NULL, 'c21_logo_fhe_pms124-WHT.png', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-124, NULL, NULL, 'CENTURY-21-Logo-Century21.png', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-125, NULL, NULL, 'Easter-Seals-Logos-2005-008-1.png', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-126, NULL, NULL, 'Easter-Seals-Logos-2005-008-2.png', NULL);
INSERT INTO `Image` (`id`,`created`,`deleted`,`fileName`,`used`) VALUES (-127, NULL, NULL, 'kids-to-camp-EN.png', NULL);



INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -115);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -116);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -117);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -118);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -119);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -120);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -121);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -122);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -123);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -124);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -125);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -126);
INSERT INTO `AgencyImage` (`agency_id`,`image_id`) VALUES   (1, -127);


ROLLBACK;

我想在提交代码之前验证运行的脚本。然而，第一次运行时它没有回滚任何东西。

我做错了什么？

它是 MyISAM 表吗？如果是这样，您需要 switch to InnoDB如果你想使用事务。如果您从诸如 PHP 之类的东西运行查询，请确保您有 autocommit关闭。
