title: SQL Server add job agent T-SQL script issue
body: <p>I am using SQL Server 2008 Enterprise. I have created a very simple test SQL Server Agent job which just print out a string. And then I add a schedule to let the job run once a day.</p>
  
  <p>Then I select from SQL Server Management Studio => Jobs => Select the test job => Script Job as => Drop and Create To, here is the generated scripts. My confusion is, when (at the bottom of the script) calls msdb.dbo.sp_add_jobschedule, there is an input parameter provided as an input parameter for this store procedure called @schedule_uid, but from MSDN, this parameter is an output parameter, and not an input parameter. Any ideas why is wrong and why such mismatching?</p>
  
  <p>Here is MSDN page and the script generated from SQL Server Management Studio,</p>
