百度了很多不知道怎么办
该错误提示表明，在执行SQL查询时找不到名为 "test" 的列。这通常发生在迁移数据库时，因为可能已经更改了数据库结构，而迁移代码中未能正确反映这些更改。
要解决此问题，请按照以下步骤操作：
确认数据库表结构：检查数据库表结构，确保表中确实有名为 "test" 的列。如果没有，请更新表结构以包含所需的列。
执行数据库迁移：运行数据迁移代码，以确保数据库结构与应用程序代码中的结构相匹配。
检查迁移代码：检查数据迁移代码，查看是否正确地更新了数据库结构。确保在修改表结构时，相应的迁移代码也已更新。
重新运行应用程序：如果您已经修改了数据库结构并重新运行了迁移代码，可以尝试重新运行应用程序，看看是否成功。
