I was just about to post a very similar question about creating a pivot table with "dynamic" column names when I found this thread. Thanks to all who contributed! In my case, this was exactly what I was looking for before I even asked!!!

Thanks,

Chris.

Chris...

I don't know if you saw the links... just in case...

I have to appologize for what they did to the code windows. They used to be almost full sized and have recently been "squished". If you copy and past the code windows to Word, first, they'll copy to SSMS or QA much more nicely.

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.

Chris, congratulations on searching before asking. You'd be surprised how many questions get asked over and over and over, often using the same terminology. 🙂

Hi All,

While working on this PIVOT thing I observed something and I have drawn a conclusion.

My sample query:

declare @test-2 table(myno varchar(25), mydate datetime, mystatus varchar(1), mytype int)

insert into @test-2

select 34001, getdate(),'G',1

union all

select 34001, getdate(),'Y',2

union all

select 34002, getdate(),'G',1

union all

select 34003, getdate(),'G',1

select * from @test-2

select mydate, myno, [1], [2]

from

(select mydate, myno, mytype,mystatus

from @test-2 ) as source

pivot(max(mystatus)

for [mytype] in ([1], [2])

) as test

The result is as expected. But if I change the first insert statement into

select 34001, getdate()+1,'G',1 no grouping happens (seems logical). So my observation was that the PIVOT function applies a grouping on its own for all values that are either not being converted to column or are not part of the aggregate function. Is this correct?

This was not stated explicitly anywhere so I thought better to run through you guys.

Bob,

You had said a totals row at end is much quicker and easier. How can I add this last row ? Summing up all the columns ?

I missed the last few posts as I was out for a long weekend.

It looks like you got it sorted ok though.

Keep referring to this site and we'll make a Maestro of you sooner than you think 😉

Jeff's articles are always a good place to start.

Yes.

we could at the same time develop another variable with all the same column names with plus signs between them and a constant "AS RowTotal" at the end

What you want is

col1,col2,col3,col1+col2+col3 as RowTotal

So you build two variables at the same time

@str1 = @str1 + (whatever the columnName is) + ','

@str2 = @str2 + (whatever the columnName is) + '+'

And finally

@str1+@str2+' as RowTotal'

Thanks, I have that for the rows. What I wanted to know was how to add up the columns and have the total below them.

Two ways off the top of my head.

1. GROUP BY with ROLLUP

2. Put your results in a temp table (or make it a cte) and then SELECT * from that and UNION ALL a query which sums the results.
