First steps with SQL Data Lens

After SQL DATA LENS starts, you must register one or more servers. To do this, right-click the Server Group node in the Server Navigator and select Add Server. Enter the required information and press OK.
If you have many servers, you can group servers into server groups. If you right-click the Server Group node (this is the main server group), you can add more groups to structure your servers.
SQL statements are executed using SQL DATA LENS sql editor. You can find this tool in many places, for example, by right-clicking on a Server node and then selecting the menu item “New query”.

Pressing CTRL+O open also a new Query editor but you must choose server and namespace.
