mysql - 引用 MYSQL 中的值

Question

我有以下 MySQL 安装 SQL 文件。我想要做的是修改，以便不再将安装 ID 引用为 31，而是引用脚本尝试运行时设置的值。有人可以帮忙吗？

# Install Easy Populate Configuration for zen cart v1.5

INSERT INTO admin_pages VALUES ('easyPopulateConfig', 'BOX_CONFIGURATION_EASY_POPULATE', 'FILENAME_CONFIGURATION', 'gID=31', 'configuration', 'Y', '26');
INSERT INTO configuration_group VALUES ('', 'Easy Populate', 'Config options for Easy Populate', '31', '1');

其他信息:(抱歉我忘了这个...)

有没有办法做到这一点，这样我就不必使用 ID 31？ 31 应该代表从 INSERT INTO configuration_group VALUES ('', 'Easy Populate', 'Config options for Easy Populate', '31', '1');. 自动生成的 ID。命令？

Answer 1

正如您所评论的 - 使用 SET:

SET @installId = '31';

然后使用@installId代替“31”:

INSERT INTO configuration_group VALUES ('', 'Easy Populate', 'Config options for Easy Populate', @installId, '1');

更新

如果 id 是上一个 INSERT 语句中的最后一个自动递增字段，则可以使用 LAST_INSERT_ID() 函数检索它:

INSERT INTO configuration_group VALUES ('', 'Easy Populate', 'Config options for Easy Populate', NULL, '1');
SET @autoId = LAST_INSERT_ID();

然后您可以使用 @autoId 变量代替上面的“31”。
