BEGIN

Create and call a stored procedure
Stored procedures can be created through a database management GUI (SQL Server example), or through a SQL statement as follows:
-- Define a name and parameters
CREATE PROCEDURE Northwind.getEmployee
@LastName nvarchar(50),
@FirstName nvarchar(50)
AS
-- Define the query to be run
SELECT FirstName, LastName, Department
FROM Northwind.vEmployeeDepartment
WHERE FirstName = @FirstName AND LastName = @LastName
AND EndDate IS NULL;
Calling the procedure:
EXECUTE Northwind.getEmployee N'Ackerman', N'Pilar';
-- Or
EXEC Northwind.getEmployee @LastName = N'Ackerman', @FirstName = N'Pilar';
GO
-- Or
EXECUTE Northwind.getEmployee @FirstName = N'Pilar', @LastName = N'Ackerman';
GO
