well here's a runnable query base don your copy/paste, but i couldn't figure out where the b 0 0 data came from for the desired results;

if you can explain it better, maybe someone can offer some better help.

;With MySampleData([REGION],[date_apprvd],[sal])

AS

(

SELECT 'a','20130101','1000' UNION ALL

SELECT 'a','20130201','2000' UNION ALL

SELECT 'a','20130301','3000' UNION ALL

SELECT 'b','20140101','4000' UNION ALL

SELECT 'b','20140201','5000' UNION ALL

SELECT 'b','20140301','6000' UNION ALL

SELECT 'c','20130101','7000' UNION ALL

SELECT 'c','20130201','8000' UNION ALL

SELECT 'c','20130301','9000' UNION ALL

SELECT 'd','20130101','1100' UNION ALL

SELECT 'd','20130201','2100' UNION ALL

SELECT 'd','20130301','3100' UNION ALL

SELECT 'e','20140101','4100' UNION ALL

SELECT 'e','20140201','5100' UNION ALL

SELECT 'e','20140301','6100'

)

SELECT * FROM MySampleData WHERE [date_apprvd] = '20130101'

ok if you have a master table of regions, you can join it agaisnt your transacitons? table?

;With Regions(REGION)

AS

(SELECT 'a' UNION ALL

SELECT 'b' UNION ALL

SELECT 'c' UNION ALL

SELECT 'd' UNION ALL

SELECT 'e' UNION ALL

SELECT 'f'

)

,MySampleData([REGION],[date_apprvd],[sal])

SELECT 'e','20140301','6100'

)

SELECT Regions.REGION,

ISNULL(SUM(CONVERT(int,MySampleData.sal)),0) AS sal,

COUNT(MySampleData.sal) AS count

my expected op is as follows

region sal count

a 1000 1

b 0 0

c 7000 1

d 1100 1

e 0 0

the ip value is 20130101, if you see my sample, you can find out b and e records doesnot have dates

20130101 , so it should display as 0

Without a master table of regions, the query can perform poorly with large data.

CREATE TABLE #MyTable(

REGION char(1), date_apprvd date, sal int)

INSERT #MyTable VALUES

('a', '20130101', 1000),

('a', '20130201', 2000),

('a', '20130301', 3000),

('b', '20140101', 4000),

('b', '20140201', 5000),

('b', '20140301', 6000),

('c', '20130101', 7000),

('c', '20130201', 8000),

('c', '20130301', 9000),

('d', '20130101', 1100),

('d', '20130201', 2100),

('d', '20130301', 3100),

('e', '20140101', 4100),

('e', '20140201', 5100),

('e', '20140301', 6100)

DECLARE @Date date = '20130101'

SELECT REGION,

SUM( CASE WHEN date_apprvd = @Date THEN sal ELSE 0 END) sal,

SUM( CASE WHEN date_apprvd = @Date THEN 1 ELSE 0 END) count

FROM #MyTable

GROUP BY REGION

DROP TABLE #MyTable

I have a feeling this thread is going like the last one from the poster. http://www.sqlservercentral.com/Forums/Topic1465520-391-1.aspx

Lots of completely vague posts and suddenly, voila! The OP posts a complete random lengthy script with the answer. We are still left wondering what the question was in the first place.

wow, just reviewed that thread, and it's like a rabbit out of the hat; i'll make sure to encourage this poster to provide real details in the future; it looked like low hanging fruit at first glance, without that context.

Lowell posted a complete solution before I did using a master table of regions and you just ignored it.

The other thread mentioned was so confusing that I wasn't even interested on trying to understand it.

Lowell and Sean are great contributors of this forum and they deserve respect as anyone willing to help you for free.

Nick, I was merely trying to help my fellow posters not waste a lot of time like I did just a day or two ago trying to extract enough information to understand the question to have you suddenly post an answer that was impossible to have achieved based on the information posted. It is too bad that you view me as a "humpty dumpty". I am probably one of the most patient people around here at trying to get posters to provide details. I stick around after everybody else has given up.

Keep in mind that we don't get paid for the stuff we do around here. We post here because we enjoy helping other people. I personally have helped hundreds of people with issues far more complicated than this one. I was able to do that because they provided the details.

I am very glad you found a solution to your issue. Please come visit us again the next time you need help. But I highly suggest you post ddl and sample in a consumable format. If not, you risk being asked for it by all the other ~~posters~~ humpy dumpty's on this site.

nicklibee I'm sorry if you took any of the comments here as harsh.

Sean and I,as well as other regular volunteers here have both contributed to tens or hundreds of thousands of posts over time, and based on that experience, we've found that as soon as we can train someone to post their question in a specific manner, they get a working testable answer in literally minutes.

If I can copy and paste some code into SSMS that is representative of the problem,

I can usually create or modify the solution very quickly.

Most people have desktop tunnel vision...they look at their problem with substantially more back story and insight than they usually able to put into a forum post.

Volunteers on the other side of the post, which only have what was pasted, and not the rest of the back story, end up asking for more clarifications.

When we help people overcome that information gap, by getting them to provide DDL and sample data, they have a better experience.

So good in fact, that is one of the main attractions here. Many first time posters spend more time here, and end up contributing and helping others themselves, writing articles, adding blogs, and joining the SQL community in a positive way.

That's all anyone here wants, is to help you become better; it's the only reason I volunteer here; I like helping people.

SQL is kind of unique compared to programming languages, because if you have a problem, you can usually paste twenty or so lines of code and get help;
