如何永久删除git存储库中的子模块?(How to permantly remove submodules in git repository?)

几天前,我使用了git的子模块功能并添加了相当多的存储库,但是我现在删除所有存储库( git submodule list返回任何内容;同样, .git/config和相关的.gitmodules不包含任何存储库存储库信息)。 但是git 保留它们:它们仍然在.git/modules目录中! 令我恼火的是他们占用磁盘空间,即使我根本不需要它们(我相信我可以随时重新添加它们作为子模块)。

那我怎么处理呢? 我可以简单地删除.git/modules目录吗?


Several days before, I used the submodule feature of git and added quite a lot of repositories, however I remove all of them now(git submodule list returns nothing; also, .git/config and the related .gitmodules do not contain any of the repository information). But git do preserve them: they are still in the directory of .git/modules directory! What annoys me is that they take disk space even I don't need them at all(also I believe I could re-add them as submodule at any time).

So how can I deal with that? Can I simply remove the directory .git/modules?

最满意答案

改变这一点

(i.StateFee + e.StateFee) AS StateFeeTotal

(ISNULL(i.StateFee,0) + ISNULL(e.StateFee,0)) AS StateFeeTotal

或者用正确的列名称

(ISNULL(i.StateFeeBegin,0) + ISNULL(e.StateFeeEnd,0)) AS StateFeeTotal

使用LEFT JOIN,你可以得到NULL值。 将NULL添加到其他任何内容将始终为NULL。 此答案使用ISNULL替换NULL值。


Change this

(i.StateFee + e.StateFee) AS StateFeeTotal

to

(ISNULL(i.StateFee,0) + ISNULL(e.StateFee,0)) AS StateFeeTotal

Or with maybe correct column name

(ISNULL(i.StateFeeBegin,0) + ISNULL(e.StateFeeEnd,0)) AS StateFeeTotal

With the LEFT JOIN, you can get NULLs for the values. NULL added to anything else will always be NULL. This answer uses ISNULL to replace NULL vales.
