sqlite是vnstudio安装好后不需做任何配置就可以用了吗？
没有设置任何数据源，只需要用自己的行情数据，可是加入行情记录后好像也看不到啊？
实际上刚添加时有这样的错误
Traceback (most recent call last):

sqlite3.OperationalError: table dbtickdata has no column named turnover
During handling of the above exception, another exception occurred:

当时点掉了，刚才又莫名点出来这个exception，幸好拷贝下来了，但是再去找却又找不到了
