@shfshihuafeng I don't think this is a bug. You are first running the query USE http which sets the root at http. Then you're running a SELECT ... FROM http.sunrise. So at that point, the plugin is looking for a path: http.http.sunrise which does not exist.

I'd bet that if you either skipped the USE query or ran a SELECT ... FROM sunrise it would work.

@cgivre You are right, but when use http, the default schema is http, when we use another data source schema, will report error.

It think this is not right.

@cgivre
when i use "use my.test" command to switch schema, It is correct to query data with full schema Name from other data sources

[cgivre]

@shfshihuafeng
So are you saying the behavior with USE is inconsistent? I want to make sure I understand the issue.

[shfshihuafeng]

@cgivre
There are two problems with this

1. behavior with USE is inconsistent
2. when i enter the scehma with 'use',data can not be queried
