使用tushare数据源，代码如果写IF2112.CFX，则提示下载0条，
如果代码写IF2112，则抛出异常。
我用pro.fut_daily是可以正常下载的。
请问如何解决？

2.5版本在数据的存储字段中加了turnover字段，本地的数据库应该没有更新，可以把本地数据库删了试试，如果有数据需要先备份出来

本地数据库删了以后，使用IF2112可以正常下载，但是 turnover列和open_interest列为空，是什么原因呢？

因为数据供应商没提过吧

数据提供商是tushare pro，金额和持仓数据都有的

在这个目录下修改一下这两行内容

或者可以等一下更新

修改这两行后能正常运行，谢谢
