尝试直接修改了一下up.sql文件
GPT knowledge:
在Hasura Migrations中,up.sql 和 down.sql 是用于描述数据库架构更改的SQL文件。
up.sql 文件:这个文件包含了应用某个特定迁移所需要的SQL命令。例如,如果你的迁移是用于添加一个新的表,那么 up.sql 文件就会包含创建那个新表的SQL命令。
down.sql 文件:这个文件包含了撤销 up.sql 中更改的SQL命令。它是 up.sql 的反操作。例如,如果 up.sql 是用于创建一个新的表,那么 down.sql 就应该包含删除那个新表的SQL命令。
Hasura Migrations使用这两个文件来确保数据库架构的更改可以被准确地应用和撤销。当你运行一个迁移时,Hasura会执行 up.sql 中的命令。如果你需要撤销那个迁移,Hasura则会执行 down.sql 中的命令。
