SQL Query: Schedule multiple jobs to run over night

I had about 40 sql agent jobs. I had to schedule them to run one time only over night. It was a bit of hectic to open every job, change the ownership, modify the schedule time, then change the ownership back to the service account. In order to minimize the work effort, I have written a script based on CURSOR. Where I will have a control table, it will define the job name, schedule name, schedule start date, schedule start time. I will read this from the control table and the change the schedule accordingly.


USE msdb;USE msdb;go
/*create the control table and insert some dummy data.In order to make this script work, there has to be job exist defined in the control table.*/
