Issue Summary
- connectting to sqlserver (2016/2017 in my case) successfully
- query some data such as Russian string form the database
- results return unreadable code
for example:
origin string is ‘200-01НАДР-201’,
redash returned string is ‘200-01§¯§¡§¥§²-201’
And I try to find out the reason and change the default tds_version to 7.1, the query result returned correct string.
And I find some instruction about the tds_version on the Internet:
https://www.freetds.org/userguide/choosingtdsprotocol.htm
It shows that the tds_version 7.0 supported sqlserver 7.0 which is not adapted to mine for the Russian or Japanese string and so on.
So perhaps it might make the defult tds_version to 7.1 to avoid the problem, it works well in my case so far.
