Example in README won't work: Registering multiple Config about sharding

这个问题有解决方案了么？

The example no longer works and was fixed in the README.
If you want to use different sharding rules, currently you can use multiple database connections.

@zishiguo We've fixed it internally. Due to the lack of maintenance of this community, we did not contributed our changes to the original repo.

BTW I am not recommand you to use this hook with gorm. We used it for couple months. There are too many issues and bugs under current implementation. Some of them are fatal. You should write sharding SQL with other plugin / manually, and should NOT use this repo in order to save your time.

@jiekun Thank you for your advice. Can you recommend other plugins ?

We abondoned the plugin way. It's hard to manage the real SQL after re-writed. If the plugin goes wrong, that would be a very big problem, like, you throw your data (which belongs to table _001) to table _003 wrongly.

AFAIK there is no perfect plugin (that supports all kind of SQL stmt, like IN / JOIN / many advance usage) in Go yet. You may try shardingsphere, which may be a lot more heavy. I recommand specifying table name with Table() method for short-term usage. Then you could evaluate shardingsphere and other proxy middleware later.
