SQL Server - Passing Values to User Defined Function Parameters in SQL Server

If a user defined function is created with parameters, you need pass values to those parameters when calling the function with one of two formats listed below:

expression... function_name(value_1, value_2, ... value_n)...

The tutorial exercise below shows you how to pass values to function parameters:

USE FyiCenterData;
GO

DROP FUNCTION Welcome;
GO

CREATE FUNCTION Welcome(@url VARCHAR(40))
   RETURNS VARCHAR(40)
   AS BEGIN
      RETURN 'Welcome to '+@url;
   END;
GO

PRINT 'Hi there, '+dbo.Welcome('dba.FYIcenter.com');
GO
Hi there, Welcome to dba.FYIcenter.com

PRINT 'Hi there, '+dbo.Welcome('dev.FYIcenter.com');
GO
Hi there, Welcome to dev.FYIcenter.com
