thanks V-lianl-msft for your reply, but the problem is not on the desktop side. When i published my dashboard on power bi service and i want to refresh datas from there, i must configure new connection string on the gateway too. I don't know what is the format/structure of this string for Snowflake provider (or ODBC for Snowflake if it works ?)

    Hi Sarazin73 ,

     

    Try the following to see if it works

    Provider=MSDASQL.1;Persist Security Info=True;User ID=USER_NAME;Extended Properties="DSN=DSN_NAME;DATABASE=DATABASE_NAME;Description=Snowflake DSII;ROLE=ROLE_NAME;SCHEMA=PUBLIC;SERVER=instancename.snowflakecomputing.com;TRACING=4;UID{USER_NAME};WAREHOUSE=WAREHOUSE_NAME;";Initial Catalog=DATABASE_NAME;Pwd=PASSWORD

     

    If the problem persists,i would suggest you to create a support ticket to solve your problem. 

     

    Best Regards,
    Liang

      I replaced the properties of the ODBC connection string with our values. Leaving the "User ID" and "Pwd" properties inside, I get the following error message: "ODBC: The connection string is not valid. The connection property 'user id' (or Pwd) can only be specified using credentials. ". By removing "User ID" or "Pwd" from the connection chain, the error message is different: "Unable to connect to the undefined data source." with error code -2147467259 and the message: "ODBC: ERROR [IM002] [Microsoft] [ODBC driver manager] Data source not found and driver name not specified" Note that on the server hosting the gateway, it is up to date and that after installing the Snowflake ODBC driver, the Azure VM has been restarted. Is there no way today (March 2020) to connect directly to a Snowflake database by choosing the type of data source: "Snowflake" as the gateway source in the Power BI service? this would have the advantage of being simpler to configure and more efficient to query.
