Once you have built your query in the Query Builder, you can run it by clicking on Run (or F5).
Where your query results go to is determined by View > Display query results on this window or the Results button on the toolbar.
If Display query results on this window is selected, the query results will go to a tab on the bottom of this window
If Display query results on this window is not selected, the query results will go to a Data Display window the next time you run your query
Using the data display tabs
This is similar to the data display tabs on the Run SQL window.
to close a tab, click on the x at the right-end of the tab title
if you want to see the data in a Data Display window, right-click the grid and select Copy to Data Display window
as you select a tab, the SQL for that data will be seen in the status-bar at the bottom of the window. You can click on this to see the full SQL.
you can Refresh the data in the tab by right-clicking the grid and selecting Refresh Grid (or Ctrl + Shift +F5)
you can "go back" to the SQL used for a display by right-clicking the grid and selecting Revert to this query. This provides a basic "undo" capability, allowing you to return to an earlier version of the query you are building.
you can remove all your tabs with View > Clear all grids
Running your query against another database
You are able to run your query against another database. This is only useful if the other database has the same tables and columns, so the query is valid on that database. To do this, select Run > Run against, and select the database.
You can export your data by clicking on Query > Export Data (F7).
You can check the syntax of your query by clicking on Query > Check Syntax (F6).
This will do a "prepare" of your query, but will not actually run it. Some databases may not support this mode of operation.
