Creating Custom Templates
SQL Server Management Studio comes with templates for many common tasks, but the real power of templates lies in the ability to create a custom template for a complex script that you must create frequently. In this practice you will create a simple script with few parameters, but templates are useful for long, repetitive scripts, too.
Using Custom Templates
To create a custom template
In Template Explorer, expand SQL Server Templates, right-click Stored Procedure, point to New, and then click Folder.
Type Custom as the name of your new template folder, and then press ENTER.
Right-click Custom, point to New, and then click Template.
Type WorkOrdersProc as the name of your new template, and then press Enter.
Right-click WorkOrdersProc, and then click Edit.
In the Connect to Database Engine dialog box, verify the connection information and then click Connect.
In Query Editor, type the following script to create a stored procedure that looks up orders for a particular part, in this case the Blade. (You can cut and paste the code from the Tutorial window.)
USE AdventureWorks; GO IF EXISTS ( SELECT * FROM INFORMATION_SCHEMA.ROUTINES WHERE SPECIFIC_NAME = 'WorkOrdersForBlade') DROP PROCEDURE dbo.WorkOrdersForBlade GO CREATE PROCEDURE dbo.WorkOrdersForBlade AS SELECT Name, WorkOrderID FROM Production.WorkOrder AS WO JOIN Production.Product AS Prod ON WO.ProductID = Prod.ProductID WHERE Name = 'Blade'; GO
Press F5 to execute this script, creating the WorkOrdersForBlade procedure.
In Object Explorer, right-click your server, and then click New Query. A new Query Editor window opens.
In Query Editor, type EXECUTE dbo.WorkOrdersForBlade, and then press F5 to execute the query. Confirm that the Results pane returns a list of work orders for blades.
Edit the template script (the script in step 7), replacing the product name Blade with the parameter <product_name, nvarchar(50), name>, in four places.
Note
Parameters require three elements: the name of the parameter that you want to replace, the data type of the parameter, and a default value for the parameter.
Now the script should look like:
USE AdventureWorks GO IF EXISTS ( SELECT * FROM INFORMATION_SCHEMA.ROUTINES WHERE SPECIFIC_NAME = 'WorkOrdersFor<product_name, nvarchar(50), name>') DROP PROCEDURE dbo.WorkOrdersFor<product_name, nvarchar(50), name> GO CREATE PROCEDURE dbo.WorkOrdersFor<product_name, nvarchar(50), name> AS SELECT Name, WorkOrderID FROM Production.WorkOrder AS WO JOIN Production.Product AS Prod ON WO.ProductID = Prod.ProductID WHERE Name = '<product_name, nvarchar(50), name>'; GO
On the File menu, click Save WorkOrdersProc.sql to save your template.
To test the custom template
In Template Explorer, expand Stored Procedure, expand Custom, and then double-click WorkOrderProc.
In the Connect to Database Engine dialog box, complete the connection information and then click Connect. A new Query Editor window opens, containing the contents of the WorkOrderProc template.
On the Query menu, click Specify Values for Template Parameters.
In the Replace Template Parameters dialog box, for the product_name value, type FreeWheel (overwriting the default contents), and then click OK to close the Replace Template Parameters dialog box and modify the script in the Query Editor.
Press F5 to execute the query, creating the procedure.
