I was testing features of QGIS and its really cool.I tried to query each table using right click and query but I can't query sql server 2008 database :
Error:
An error occured when executing the query.
The data provider said:
[microsoft][odbc sql server driver][sql server] invalid object name 'table_test'
qodbc3:unable to execute statement
but it works fine with postgis. :Also is there any why to join table and do the query?
