Hi,

I need to retrieve dates (and other fields) from different rows. How do I accomplish this?

Data looks like:

plan_num	call_num	package_num	completed_date	next_scheduled_date	job_id
123456	1	1	20130112	20151231	1000000
123456	2	1	20140224	20160317	1000000
123456	3	1	20141213	20170202	1000000
123456	4	1	20150917	20171121	1000000
123456	5	1	00000000	20181121	1000000
789012	1	1	20150713	20151229	1000000
789012	2	1	20160821	20160708	1000000
789012	3	1	00000000	20170824	1000000

The user will type in the job_id. I need to return plan_num, package_num, the most recent completed date and the scheduled date from the row following the most recent completed date. So, in this case, the user will type in job_id 1000000 and I need to return all of the following:

123456 1 20150917 20181121
789012 1 20160821 20170824

Thank you!

I recommend you post your data according to the methods depicted at the first link in my signature line below under "Helpful Links". People will produce a coded response for you that has actually been tested.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
