How to: Add New Items to a Project
Add new items to a project to extend application functionality. A new item can be a query or a connection. SQL Server Management Studio has three project types: SQL Server Script Project, Analysis Services Script Project, and SQL Server Compact 3.5 SP1 Script Project. The project type determines the items that you can add to the project. For example, you can add a Transact-SQL query (a file with a .sql extension) to a SQL Server Script project, but you cannot add it to an Analysis Services Script Project.
SQL Server Management Studio does not allow you to create folders within projects. To organize your work, create multiple projects within the solution.
To add a new query to an existing project
In Solution Explorer, select a target project.
On the Project menu, click Add New Item.
In the Add New Item dialog box, select a category in the left pane.
Select a query template in the right pane, and then click Add. The new query is added in the Queries folder of the project.
In the Connect to Database Engine dialog box, specify a connection for the new query, and then click Connect. You can click Cancel on the connection dialog if you do not want to associate a connection to the new query.
Rename the query in Solution Explorer if you wish.
