Using Group By

Jun 2, 2008

Hello,

I've been asked to remove all duplicate records from a database of names and address

The database is structure like this

Firstname
lastname
add1
add2
postcode
city
email

I am trying to remove the duplicates by using the group function. But I only want to group those who have the same last name and add1.

So I use this to do so...

SELECT LastName, Add1

FROM players

GROUP BY LastName, Add1;

So that works fine. But is there a way I can add the other columns (add2, firstname etc) to the results page?

If I do it this way...

SELECT Firstname, LastName, Add1, add2, postcode, city, email

FROM players

GROUP BY Firstname, LastName, Add1, add2, postcode, city, email

It wont give me an accurate result. Any suggestions how I should do this? Sorry, I'm pretty green when it comes to databases

Thanks

John

Reporting Services :: Display Group Name Value Of Each Group In Column Header Outside The Group?

Sep 29, 2015

I have an SSRS 2012 table report with groups; each group is broken ie. one group for one page, and there are multiple groups in multiple pages.

'GroupName' column has multiple values - X,Y,Z,......

I need to group 'GroupName' with X,Y,Z,..... ie value X in page 1,value Y in page 2, value Z in page 3...

Now, I need to display another column (ABC) in this table report (outside the group column 'GroupName'); this outside column itself is another column header (not a group header) in the table (report) and it derives its name partly from the 'GroupName'  values:

Example:

Value X for GroupName in page 1 will mean, in page 1, column Name of ABC column must be ABC-X Value Y for GroupName in page 2 will mean, in page 2, column Name of ABC column must be ABC-Y Value Z for GroupName in page 3 will mean, in page 3, column Name of
ABC column must be ABC-Z

ie the column name of ABC (Clm ABC)  must be dynamic as per the GroupName values (X,Y,Z....)

Page1:

GroupName                 Clm ABC-X

X

Page2:

GroupName                 Clm ABC-Y

Y

Page3:

GroupName                 Clm ABC-Z

Z

I have been able to use First(ReportItems!GroupName.Value) in the Page Header to get GroupNames displayed in each page; I get X in page 1, Y in page 2, Z in page 3.....

However, when I use ReportItems (that refers to a group name) in the Report Body outside the group,

I get the following error:

Report item expressions can only refer to other report items within the same grouping scope or a containing grouping scope

I need to get the X, Y, Z ... in each page for the column ABC.

I have been able to use this - First(Fields!GroupName.Value); however, I get ABC-X, ABC-X, ABC-X in each of the pages for the ABC column, instead of ABC-X in page 1, ABC-Y in page 2, ABC-Z in page 3, ...

What's Microsoft Doing About Providing Page Numbering Per Group And Total Pages Per Group?

Nov 27, 2007

Hi!

I've posted a feedback with Microsoft to see if we can get them to fix the issue described below, but so far no one from Microsoft has commented to let us know what they're doing about this problem! I'm posting this here to see if maybe we can get more people to rate this feedback or chime in on what a pain it is! Please feel free to add your own comments or how you had to work around this issue and whether or not you think this is something Microsoft should be addressing NOW.


https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=311679

Provide Individual Page Numbering per Group and Total Pages per Group

Currently in a Reporting Services report, you can't readily reset the page number for each group in a table, nor can you display the total number of pages per group. For example, if I'm printing invoices and each invoice is a separate group, I'd like to be able to print "Page 1 of 5" , "Page 2 of 5" etc. for the first invoice, then "Page 1 of 3" when the next invoice begins, and so on. This was easy in Crystal Reports. I realize that Crystal Reports has a two-pass process that enables that kind of pagination. However, this is REALLY important functionality that's just missing from Reporting Services and I'm hoping you'll provide it REALLY SOON! Yeah, I know there are work-arounds if you can know exactly how many rows of information there are on each page. But gosh! That's not practical, especially if you have second level groups inside the main group or text blocks in rows that can 'grow' to more than one line. I've read a couple of work-arounds, but none of them works correctly and consistently when more than one user is running the same report or when you print the report while you're looking at it on the screen. I still may need access to the overall report page number and the overall total number of pages, so don't get rid of that. It's just that if you're doing this already for the entire report, I don't see why you can't do it per group! Lots of people have been asking for this for years, and I don't understand why it hasn't been implemented.


I've read a few articles on this topic, but no one has come up with a decent work around. My theory is that Microsoft should be addressing this immediately. This is major functionality that's just plain missing from SSRS and should have been there from the start. If anyone from Microsoft can let us know what's going on with this issue or if anyone would like for me to clarify this further, feel free to let me know.


Thanks!
Karen

Reporting Services :: RDL XML To Unmerge Cells In Group BUT Keep Group Drill-In In Excel

SQL Server 2012 :: Obtaining A Comma Delimited List For Each Group In The Output Of A Group By Query?

Jan 10, 2014

I'd like to ask how you would get the OUTPUT below from the TABLE below:

4 A
5 B
6 C
7 B

OUTPUT:

category count id's
A 3 1,3,4
B 2 5,7
C 2 2,6

The code would go something like:

Select category, count(*), .... as id's
from TABLE
group by category

I just need to find that .... part.

SQL 2012 :: SSRS Average Column Group Value For Row Group

Feb 28, 2014

I'm having a fight with Reporting Services at the minute when trying to compute an average at the row group level for a value summed in a column group.I have the following column groups:

Year
Month
Date

And the following row groups:

Region
Product
SubType (hidden, data at the date level is summed to Product)

At the moment I'm computing the average for SubType for each Date at the Product level (giving a decimal value), so for each day I end up with a nice average, that works. However I am unable to average that average over the whole Year for a Product. The issue being that I'm trying to combine Row Groups (Product) and Column Groups (Date/Year)

Login For Domain Local Group And Global Group

Jan 5, 2008

I have one domoain in the forest. The domain level is set to Windows 2000 native mode and forest level is set to mixed mode. My SQL server 2005 server joined to this domain. I added a brand new domain local group and add a normal user account to this domain local group. I login to the SQL server 2005 server and make a query "SELECT * FROM sys.login_token". I cannot see my domain local group in sys.login_token. However, if I add my account to a global group, I can see it there.

Then, I setup another forest. This time, I have domain level set to Windows 2003 mode and forest level is set to Windows 2003 native mode. I do the same testing. This time, I can see my domain local group in sys.login_token.

Why does SQL server 2005 has this limitation? Is it a bug?

How?: Group By Date And Count Rows In Group

Jan 29, 2007

I'm new to MSSQL 2005 and want to get a summary of a log table. I want to count all the rows for each date based on a DATETIME field called 'post_date' that holds the date and time of each record's creation.

this is the best I can come up with:

Code:


SELECT
DISTINCT(LEFT(post_date,11)) AS post_date, COUNT(DISTINCT(LEFT(post_date,11))) AS total_posts
FROM log_directory_contacts
GROUP BY post_date



The results show each date but the count column ('total_posts') returns '1' for every row even when I know their are more than 1 record on that date.

What am I doing wrong? Thanks!

Repeat First Row Group Header For Second Row Group Items

Jun 6, 2007

I have a matrix with two row groups and one column group with about 6 items in it. I have about 2100 rows at the lowewst row group level. This report was built solely for excel export. The first row group has about 20 items and controls the visibility of the other group. When I toggle the visibility of the second row group, how can I make the the header of the first row group copy down for each row of the other row group? The first row group is the Section and the second is Mnemonic.



Example:

Now:

T-SQL Problem...selecting TOP 1 Of Each GROUP In GROUP BY?

Jul 23, 2005

Hi,I was hoping someone may be able to help me with a tricky T-SQLproblem.I need to come up with a SELECT statement that does basically thefollowing:Select RCRD_REFNO, MAX(MODIF_DTTM) as MODIF_DTTM from[StageDb].[dbo].tblPersonInfo group by RCRD_REFNOHowever, I need to select ONLY the TOP 1 of each group (i.e. only 1record for each unique RCRD_REFNO). The problem is of course that if Iadd 'top 1' after select, it only brings back 1 record full stop,rather than 1 for each group!Now, I have previously come up with a similar query that DOES do thissuccessfully, but it relies on a criteria (such as a unique identifier)-unfortunately, the nature of the table I'm using for this currentjob means that it actually doesn't have a primary key, as it'ssimply a staging area for raw data, and can even have completelyidentical records in it. I think the only way I'm going to be able todo it is to literally use the 'TOP' command somehow, but am notsure how to adapt the above to implement it...I'd be very gratefulfor any advice.Many thanks

Adding SubTotol Of A Group To Group

Sep 6, 2007

Here is my Table Structure ( from Oracle database)
Team | Customer Code | Amount | Credit Limit
1 , a, 100, 1000
1 , a , 200, 1000
1 , b, 100, 100
1, b, 1000, 100
1, b, 2000, 100
2, a, 100, 2000


For the Report, I want to group the Team and Sum each customer total Amount and Show the Exceed limit amount.
Here I want to present
Team Customer Code Amount Credit Limit Exceed
1 a 300 1000 0
1 b 3100 100 3000
Team Total 3300 3000
2 a 100 2000 0
Team Total 100 0
Total 3400 3000

BUT it turn out..
Team Customer Code Amount Credit Limit Exceed
1 a 300 1000 0
1 b 3100 100 3000
Team Total 3300 2300 ( Problem here a )
2 a 100 2000 0
Team Total 100 0 ( Problem here a )
Total 3400 2400 ( Problem here b)


I Grouped the Custoer Code and Team I can preform the sum
however I can't Do the Exceed total
becoz the value should be
iif (Sum(amount)>(Creditlimt) , Sum(amount)-First(Creditlimt), 0)
but for the team total in team 1 the result is 2300 ( 3300 - customer a 's limit) not add from exceed amount
And the finial total it turns out 2400 (3400 - 1000)

I have tried use the coding to sum up the exceed
but I found that the group total is sumup first than the sum up the detail :

Team Customer Code Amount Credit Limit Exceed
1 a 300 1000 0
1 b 3100 100 3000
Team Total 3300 0
2 a 100 2000 0
Team Total 100 3000 ( The Total from Team 1 ! )
Total 3400 0 ( Problem here b)


this situration , I can't change the query statement
I can do the good result for CR report
but for reporting service 2005, I can't to the first report result
Any one can help me ??
thank you

Sum In A Group Based On Other Group Value

Dec 4, 2007



Hi all,
I have a Report and I have used Table in the report to define 5 levels of Sub Groupings: Group1, Group2, Group3, Group4, grpResourceBehavior.

The Sample data which comes is:
Group1 Group2 Group3 Group4 ResourceBehavior BgtHrs BgtAmt
A1 B1 C1 D1 NML 12 12
A1 B1 C1 D1 ODC 0 12

Now, to calculate a field "Cost", I have to use following condition. If the ResourceBehavior is NML, then Cost = BgtAmt/BgtHrs
But, if the ResourceBehavior is ODC, then COst = BgtAmt/(SUm of BgtHrs for the resourcebehavior NML)

I am not able to calculate the Sum of the BgtHrs for different ResourceBehavior. Also, I need this field calculation for each and every group as well, and this makes it all the more complicated.

Any help is appreciated.

Thanks in advance.

SUBTRACT A VALUE FROM ONE GROUP FROM A VALUE OF ANOTHER GROUP!

Mar 14, 2008



OK, hope I can explain what I need....

I have a report, which SUMS a value and groups on another field (campaign). What I need to be able to do, is take the SUMMED value from the 1st group, and subtract from this value, the value of the SUMMED value of the second group.

Example:

CAMPAIGN VALUE
CAMPAIGN A 5,000
CAMPAIGN B 1,100

I'd like to be able to subtract 1,100 from 5,000 - but can't find out how this can be done....don't forget these are grouped item's not just rows from the dataset.

I am fairly new to SSRS, so please go easy on me if this is something simple (i hope it is!)

Thanks for your help

Can we group the data to get this kind of result without using cursor?
Any help is appreciated!

Thank you,

Group By...Having

Oct 15, 2001

I have the following SQL Statement:

Select Distinct top 10 line + '-' + subline,
substring(convert(char,job_cd), 1, 6),
count(job_cd)
From call inner join skuref on call.itm_no = skuref.sku
left join jobcode on call.[key] = jobcode.[key]
where line Like '42%'
and subline Like '15%'
and source Like '358%'
and sku Like '77310%'
group by line + '-' + subline,
Substring(Convert(char, job_cd), 1, 6)
having substring(Convert(char, job_cd), 1, 6) Like '%'
order by count(job_cd) desc

Whenever I try to run this statement I get an error saying: Column 'jobcode.job_cd' is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause.

Is is just because of the I'm trying to convert it from an integer to a string (Substring(Convert(Char, job_cd), 1, 6)?
