How to: Open Queries (Visual Database Tools)
You can open an existing query in Query and View Designer by using the Open command.
To open a query in all panes
From the View menu, click Solution Explorer.
In Solution Explorer, right-click the query you want to open and click Open.
To modify the query in Query Designer, highlight the SQL statements, right-click the highlighted area and select Design Query in Editor.
By default the Query and View Designer opens all of its panes (SQL, Criteria, Diagram, and Results), but that default can be changed in the Options dialog box. To open these panes if they are closed, from the Query Designer menu, point to Pane, and then click the pane you want to open.
