I have one table that contains all my data. I can group into a result as below (the weight would the the sum per day):
Time_____________________Plant ______Weight
01/03/2013 10:00___________AP1________1.2
02/03/2013 11:00___________AP1________2.3
03/03/2013 12:00 __________AP1 ________1.1
01/03/2013 10:00 __________AP2_________1.4
02/03/2013 10:00 __________AP2 ________1.1
03/03/2013 10:00 __________AP2_________1.1
How do I go about splitting the sum(weight) up into seperate columns based on 'Plant' so the query result looks like this:
Time_____________________AP1______AP2
01/03/2013 10:00__________1.2_______1.4
02/03/2013 11:00__________2.3_______1.1
03/03/2013 12:00__________1.1_______1.1
Basically I want to group the results into columns rather than one long result.
Thanks

What you are referring to is called a cross tab or pivot. See the articles in my signature about those topics.

Thanks, Sean. Good article. You know, I'm consistently impressed by just how many different uses there are for the tally table. So simple in design, yet the performance gains are through the roof. Thanks again.

One of the regulars around here (I always forget who) once called it the "Swiss Army Knife of SQL". They were absolutely correct. The usage of something so simple is truly amazing. 😎

That would be none other than Gianluca Sartori, the "spaghetti dba".

--Jeff Moden

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.

Thanks for remembering Jeff. His assessment is so spot on that I often refer to it myself the same. 😛
