MSSQL, ODBC, Invalid cursor state, не могу подключить MSSQL базу в КХ клиенте

[Azamat Kyrykbayev]

Добрый день,
помогите с подключение по odbc к базам MSSQL

настроили odbc на clickhouse сервере, подключение с таких клиентов как isql, tsql есть, но подключиться с КХ клиента не удаётся

1. /etc/odbcinst.ini

[FreeTDS]
Description     = FreeTDS
Driver          = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
Setup           = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
FileUsage       = 1
UsageCount      = 5

2. /etc/freetds/freetds.conf

[MSSQLAzure]
	host = azalab.database.windows.net
	port = 1433
	tds version = 7.0
	#tds version = 5.0
	client charset = UTF-8

3. /etc/odbc.ini

[MSSQLAzure]
Driver = FreeTDS
Servername = MSSQLAzure
Port = 1433
Database = analytics
UID = clickhouseuser
PWD = clickhousepassword

4. Проверка подключения к MSSQL базе по ODBC

root@srv1:/# isql -v MSSQLAzure "clickhouseuser" "clickhousepassword"
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+
SQL> SELECT * from analytics.costs
ВЫВОД ДАННЫХ ...............

root@srv1:/# tsql -v -S MSSQLAzure -D analytics -U clickhouseuser
Password: 
locale is "C.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Setting analytics as default database in login packet
Changed database context to 'analytics'.
Changed language setting to us_english.

5. подключение с КХ клиента и сама ошибка = = =
root@srv1:~# clickhouse client -u admin --password adminpassword

я пробовал подключать через официальные ODBC драйвера, вместо FreeTDS
посмотрите как у меня настроено, попробуйте воспроизвести

Anybody find a solution?

This is related to clickhouse server and clickhouse-odbc-bridge, not clickhouse-odbc driver. I suggest moving the discussion to https://github.com/ClickHouse/ClickHouse/issues.
