I am using SQL Server 2008 Enterprise. I created a very simple SQL Server Agent test job that just prints a string. And then I add a schedule so that the task runs once a day.
Then I select from SQL Server Management Studio => Jobs => Select a test task => Script Job as => Drop and Create To, here are 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 storage procedure called @schedule_uid, but from MSDN this parameter is an output parameter, not an input parameter. Any ideas why this is wrong, and why such a mismatch?
Here is the MSDN and Script page generated from SQL Server Management Studio,
