I'm trying to create a report in SSRS where I have a matrix, which has gender as the column headings and specifically defined agegroups as the rows. The report is sorted by date (ie, the records being displayed are filtered by the modifedAt value). My problem is that i wish for all of the age group categories to be displayed, even if the dataset does not return any data for that row.
So, for example, if i set the date to be a date where there are no db rows where there are Age5-16 children in - I still want to display the category name, but just have the cells related to that row to display '0'. Instead, the report just drops the whole row because, obviously the query returns no data.
Is the solution to have a separate dataset that brings back the entire list of categories and then somehow fit them together? I'm stuck here so any help is appreciated!
I can think of a few ways to do this:
DataSet level
Instead of just returning the relevant data in the underlying data in the DataSet, include all the categories you want to display in all cases.
e.g. For a database query it might be the difference between an inner and left join, i.e. going from something like:
select *
from AgeGroup
inner join MyData on ...
to:
select *
from AgeGroup
left join MyData on ...
So the report always has all the age groups to display. Where there are NULL values, just display 0.
I think this is the best option if you have control over the DataSet - you won't have to update your report at all, with luck the actual DataSet changes should be minimal, there is still only one DataSet call, and it's by far the simplest to maintain.
Hard code groups into the report
Here you include a table header row for each group you want to display, so these are always displayed in all cases.
Here you have some sort of conditional expression to display the values, e.g. For each group row it will be tailored to that group:
=Sum(IIf(Fields!AgeGroup.Value = "5-16", Fields!Amount.Value, Nothing)
This is not too flexible and will need updates as you change groups, and doesn't have as many options for layout. There is still only one DataSet call, so that is a plus.
Subreports
You can have a parent DataSet that displays one row for each age group, then embed a subreport in each row that displays the data you want for that row.
This allows you flexibility in layout but it will add complexity to the report(s) and will mean that you make a lot of DataSet calls that could be avoided with other options.
I know this is old, but I wanted to elaborate on Ian's section 1 above using joins at the dataset level. (His answer was super helpful to me for a report I'm working on.)
per op:
Is the solution to have a separate dataset that brings back the entire list of categories and then somehow fit them together?
That is how I've handled it successfully, but you can do so without actually creating a separate dataset by using common table expressions (or temp tables, of course).
For these example tables:
AGE_Table
ID Group Group_Desc Toys
1 A 00-10 Teddy Bear
2 B 11-20 Video Game
3 C 21-30 Sports Car
4 D 31-40 Mansion
5 E 41-50 Jewelry
People_Table (filtered for whatever date)
ID Name Age Gender Age_Group
1 Ariel 07 F A
2 Brandon 23 M C
3 Chelsea 27 F C
4 Derek 06 M A
You want to see 2 results for the 00-10 row, 2 for the 21-30 row, and then still see rows for the other age groups even if there aren't any results.
We want to create a dataset with all the different age groupings and then join on it. Behold a solution using common table expressions:
with CTE_Age AS
(SELECT Distinct Age_Group from AGE_Table)
SELECT ID, Name, Age, Gender, CTE_Age.Age_Group FROM People_Table
RIGHT JOIN CTE_Age ON
People_Table.Age_Group = CTE_Age.Age_Group
This will return:
ID Name Age Gender Age_Group
1 Ariel 7 F A
4 Derek 6 M A
NULL NULL NULL NULL B
2 Brandon 23 M C
3 Chelsea 27 F C
NULL NULL NULL NULL D
NULL NULL NULL NULL E
Once you have that in your dataset, you can change NULL values to 0 on the report builder side -- I think in 2008R2 the default is just blank.

I am struggling to get the desired results i need using an Access query, and was wondering if what i was looking to do was actually achievable in one query, or whether i would need two queries and then export to Excel and interrogate the results there.
I've a table with a number of columns, i am specifically looking at three columns
Row Type - this will either be populated with A or U
Account Number - there will be potentially multiple instances of account number within the table. Although only once against row type "A", and multiple on row type "U"
Value - a currency field. At Account number level, the sum of "U" row, should equal the "A" value
I am looking to produce a query that will list three things.
[Account Number]
Sum of [Value] when [RowType] = "U"
[Value] when [RowType] = "A"
Would i need to create a new column in my table to generate a value for the requirement "Sum of Value when 'U')
I've tried
SUM(IIF([ROWTYPE]='U',[Value],0)) - but that doesn't seem to work.
I've also tried to use the builder within the Query to replicate the same, but again that also doesn't seem to work.
If all else fails i'm content to have to run two queries in Access and then join Excel, but i tihnk for my own learning and knowledge it would be good to know if what i am trying to do is possible.
I was hoping this is possible to compile in Access, but my knowledge of the application is seriously lacking, and despite looking on the MS Access support pages, and also some of the response on the StackOverflow forums, i still can't get my head around what i need to do.
Example of the data
Row Type
Account ID
Value
A
123456789
50.00
U
123456789
30.00
U
123456789
20.00
A
987654321
100.00
U
987654321
80.00
U
987654321
20.00
The data has been loaded into Access, table called "TEST"
This is the SQL i've got, but doesn't give me the desired results.
SELECT [TEST].[ROW TYPE], SUM([TEST].[VALUE]) AS [TEST].[ACCOUNT ID]
FROM [TEST]
GROUP BY [TEST].[ROW TYPE], [TEST].[ACCOUNTID]
When the query generates, would hope to see two rows, one for each account number.
Three row -
Account Number
Sum Value (where row is U)
Value (Where row is A)
I currently get 4 rows in the query. Two results for each account number, one result is the Value when Row Type = A, the other when Row Type = U.
I guess this is what you are after:
SELECT
[Account ID],
Sum(IIf([Row Type]="A",[Value],0)) AS A,
Sum(IIf([Row Type]="U",[Value],0)) AS U
FROM
TEST
GROUP BY
[Account ID];
Output:
Account ID
A
U
123456789
50,00
50,00
987654321
100,00
100,00
Have two tables users and user_demographics
users has the basic structure of (does have more fields but not needed here):
id name email gender age ethnicity
1 test1 test1#test.com 1 1 1
2 test2 test2#test.com 1 2 1
3 test3 test3#test.com 2 3 2
4 test4 test4#test.com 3 1 1
5 test5 test5#test.com 2 4 5
**Gender**:
1 - Male,
2 - Female,
3 - Prefer not to say
**Age**:
1 - 16-20,
2 - 21-24,
3 - 25-30,
4 - 31-24
**Ethnicity**:
1 - White,
2 - Black,
5 - Prefer not to say
and so on and currently have around 1000 users.
user_demographics structure is:
coreid, type, option (for the sake of this question 'type' will be text, just to make it clearer)
coreid, type option
1 gender 1
1 gender 2
1 age 1
1 age 3
1 ethnicity 1
2 gender 2
2 gender 3
2 age 3
3 gender 1
On a web based form I have 3 sets of checkbox lists, one for each option gender, age, ethnicity and the a user can select multiple from each. They click update and these details are stored in the mysql database as above. coreid is related to another table, but not relevant here.
What I'm trying to do is get a total count of users for each coreid regardless of what type it is. The count should get smaller the more options you select. So coreid 3 should have the biggest count because I've only selected one option.
Example: coreid 3 is selecting all males
Example: coreid 2 is selecting all (females AND 'prefer not to say') AND age range 25-30
Struggling on how to create a single query that will give me the results I need, hope this makes sense.
The idea behind the over all system is that we have a large form that a user fill outs and we store in the information in the users table. Then a member of the admin team can go in and select these users by selecting options from the various demographics information we have collected. So they might just want to see everyone that has ticked the gender options of 'male' and 'prefer not to say' for example. Another admin member may go in and say they want all males, between the age of 25-30. Or they could just tick all options under gender. The idea is that they can select any combination and get a list of results. At the minute I just need to get a count back for the combination selected.
By the SOUNDS of it, you are probably going to need to do with dynamic SQL where you actually build the query on-the-fly, then execute that. Also, to clarify what I THINK you are asking is as follows. CoreID is like a set of filters that some manager is interested in getting count and or details of specific users. They are interested in
EITHER gender condition (1 or 2)
AND EITHER age condition (1 or 3)
AND just the one ethnicity
to possibly target products that might hit those demographics. So you would pre-query every record for CoreID = 1 then start building your query. You would want to order your query by the TYPE to group common items such as the gender, age, ethnicity categories.
Then, within your either localized code (not indicated such as C#, VB, java, whatever), you would need to build the query in such a way that you parenthesis OR those within same category, and logical AND between different such as
where
( Gender = 1
OR Gender = 2 )
AND ( Age = 1
OR Age = 3 )
AND ( Ethnicity = 1 )
If you are trying to write as a MySQL stored procedure, it would be a type of dynamic SQL query... either way, the WHERE clause needs to be constructed from the Core criteria someone is looking for.
You are correct, the last one would be easiest for CoreID = 3 would be a simple
WHERE ( Gender = 1 )
Clarify language source and I or others might be able to offer additional direction, but if I am accurate, you should try to write your own first pass of code, but I will shoot out a pseudo-code for you something like
Get Records Ordered for one CoreID, order by the type of criteria.
prep variable identifying if pending open Parenthesis
prep variable identifying last "type" building for.
for each record
If new type
if has Open Parenthesis
add closing paren
add logical AND before the next entry we are getting
add open parenthesis
set flag we have open parenthesis
else
since same type as last type, add logical OR
go to next record, repeat.
If after last record we would always need to close parenthesis even if a single criteria
I got a request from the client when using SSRS reporting Service. I am kind of new to the SSRS. hope that someone can help me out with the problem below.
I use a common example to show the problem.
In SSRS dataset1, the data is like follows
StuId StuSubject
--------------------------------
1 "Math"
1 "Geography"
2 "Science"
3 "Math"
3 "History"
3 "Music"
In the SSRS dataset2, the data is like this one
StuId StuName
------------------------
1 "Tom"
2 "Joseph"
3 "Linda"
In the SSRS DataSet3 , it would be like
StuId StuInt
--------------------------
1 "Swim"
2 "Chess"
2 "Swim"
2 "Running"
3 "Game"
What i want in the SSRS report would be like this one
StuId StuName StuSubject StuSubject StuSubject StuInt StuInt StuInt
1 "Tom" "Math" "Geography" NULL "Swim" NULL NULL
2 "Joseph" "Science" NULL NULL "Chess" "Swim" "Running"
3 "Linda" "Math" "History" "Music" "Game" NULL NULL
The tricky part is that I don't know what is the maximum number of StuSubject for all these students, or more precisely, I don't like to set the limit of the 'StuSubject' columns because there could be hundred columns in the real case. I have thought of LookupSet function, but seems using LookupSet, you can only join multiple StuSubjects values with "," in one cell.
Any advice / suggestion would be much appreciated and thanks in advance
Edit : I could use Matrix control for one "join" situation, but is this possible to "join" multiple datasets into one finale one ?
The solution for you is to use Matrix report item - it allows to perform data grouping by rows and columns. Your data, returned from DB, should be aggregate of those two datasets that you have - it should be set of rows in format (StuId, StuName, StuSubject).
You can then add row grouping by StuId (and child row grouping by StuName, but this is not necessary), and add column grouping by StuSubject. Details cell will simply output StuSubject.
Notice that although Lookup* functions allow you to do join data while processing the report, they are run while processing report by SSRS and thus are certainly less efficient (from my experience expressions almost always have really bad impact on report performance). Also, doing join whikle processing report is not a canonical way to develop the report, and not the best way to use SSRS engine, which works good when you need simple grouping or do not need grouping at all. The best approach is to generate SQL result as much close to what you want to display, as it is possible, taking into account context of report and common sense of course.
Follow the below steps:
Use your DataSet1 in your matrix as suggested approach from LINK.
Your query would be similar to below:
Select StuId,StuSubject
'StuSubject' + Cast(row_number() over (partition by id order by score) as INT) StuSubjectVal
from table
You should get the result like below (after using matrix).
StuId StuSubject1 StuSubject2 StuSubject3......
Add a column to your matrix, and use the Lookup from DataSet1 to DataSet2.
=Lookup(Fields!StuId.Value, Fields!StuId.Value, Fields!StuName.Value, "DataSet2")
Have not tested it, but it should work.
I am asking this question in the hope there is a more efficient (faster) way to pull and insert data in the the tables I am working with.
The basic structure of the data table is
ID Doc_ID Field Value
1 10 Title abc
2 10 Abstract xyz
3 10 Author Bob
4 11 Publisher Bookworms
5 11 Title zzz
6 11 Abstract bbb
7 12 Title aaa
8 12 Sale No
In other words the data tables are row based, each row contain a document id and the corresponding field value. Not all documents have the same number of fields defined. Indeed books may differ radically from magazines.
The data table is 10,000,000 rows typically a document has 100 fields associated with it.
So the performance problem I am finding is pulling a report with reference to 50+ different fields, for example if I have a query list in an order_table the query could be like
select ord.number as 'Order ID', d1.value as 'Title', d2.value as 'Author' .......
from order_table ord
LEFT JOIN data_table as d1 on d1.Doc_ID=ord.Doc_ID and d1.Field='Title'
LEFT JOIN data_table as d2 on d2.Doc_ID=ord.Doc_ID and d2.Field='Author'
........
LEFT JOIN data_table as d50 on d50.Doc_ID=ord.Doc_ID and d50.Field='Qty'
Using LEFT JOINS as there is no guarantee that the field is defined for that document.
Given there may be some WHERE parameters to limit the list to items (in stock for example or below a price) it is a slow query. Indexes don't really much.
Without being able to change the data model, what is the best way to pull volumes of information out?
Hey. I have 160 columns that are filled with data when a user fills a report form out and submit it. A few of these sets of columns contain similar data, but there needs to be multiple instance of this data per record set as it may be different per instance in the report.
For example, an employee opens a case by a certain type at one point in the day, then at another point in the day they open another case of a different type. I want to create totals per user based on the values in these columns. There is one column set that I want to target right now, case type. I would like to be able to see all instances of the value "TSTO" in columns CT1, CT2, CT3... through CT20. Then have that sorted by the employee ID number, which is just one column in the table.
Any ideas? I am struggling with this one.
So far I have SELECT CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, CT9, CT10, CT11, CT12, CT13, CT14, CT15, CT16, CT17, CT18, CT19, CT20 FROM REPORTS GROUP BY OFFICER
This will display the values of all the case type entries in a record set but I need to count them, I tried to use,
SELECT CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, CT9, CT10, CT11, CT12, CT13, CT14, CT15, CT16, CT17, CT18, CT19, CT20 FROM REPORTS COUNT(TSTO) GROUP BY OFFICER
but it just spits an error. I am fairly new to mysql databasing and php, I feel I have a good grasp but query'ing the database and the syntax involved is a tad bit confused and/or overwhelming right now. Just gotta learn the language. I will keep looking and I have found some similar things on here but I don't understand what I am looking at (completely) and I would like to shy away from using code that "works" but I don't understand fully.
Thank you very much :)
Edit -
So this database is an activity report server for the days work for the employees. The person will often open cases during the day. These cases vary in type, and their different types are designated by a four letter convention. So your different case types could be TSTO, DOME, ASBA, etc etc. So the user will fill out their form throughout the day then submit it down to the database. That's all fine :) Now I am trying to build a page which will query the database by user request for statistics of a user's activities. So right now I am trying to generate statistics. Specifically, I want to be able to generate the statistic of, and in human terms, "HOW MANY OCCURENCES OF "USER INPUTTED CASE TYPE" ARE THERE FOR EMPLOYEEIDXXX"
So when a user submits a form they will type in this four letter case type up to 20 times in one form, there is 20 fields for this case type entry, thus there is 20 columns. So these 20 columns for case type will be in one record set, one record set is generated per report. Another column that is generated is the employeeid column, which basically identifies who generated the record set through their form.
So I would like to be able to query all 20 columns of case type, across all record sets, for a defined type of case (TSTO, DOME, ASBA, etc etc) and then group that to corresponding user(s).
So the output would look something like,
316 TSTO's for employeeid108
I hope this helps to clear it up a bit. Again I am fairly fresh to all of this so I am not the best with the vernacular and best practices etc etc...
Thanks so much :)
Edit 2 -
So to further elaborate on what I have going on, I have an HTML form that has 164 fields. Each of these fields ultimately puts a value into a column in a single record set in my DB, each submission. I couldn't post images or more than two URLs so I will try to explain it the best I can without screenshots.
So what happens is this information gets in the DB. Then there is the query'ing. I have a search page which uses an HTML form to select the type of information to be searched for. It then displays a synopsis of each report that matches the query. The user than enters the REPORT ID # for the report they want to view in full into another small form (an input field with a submit button) which brings them to a page with the full report displayed when they click submit.
So right now I am trying to do totals and realizing my DB will be needing some work and tweaking to make it easier to create querys for it for different information needed. I've gleaned some good information so far and will continue to try and provide concise information about my setup as best I can.
Thanks.
Edit 3 -
Maybe you can go to my photobucket and check them out, should let me do one link, there is five screenshots, you can kind of see better what I have happening there.

The query you are looking for would be very long and complicated for your current db schema.
Every table like (some_id, column1, column2, column3, column4... ) where columns store the same type of data can be also represented by a table (some_id, column_number, column_value ) where instead of 1 row with values for 20 columns you have 20 rows.
So your table should rather look like:
officer ct_number ct_value
1 CT1 TSTO
1 CT2 DOME
1 CT3 TSTO
1 CT4 ASBA
(...)
2 CT1 DOME
2 CT2 TSTO
For a table like this if you wanted to find how many occurences of different ct_values are there for officer 1 you would use a simple query:
SELECT officer, ct_value, count(ct_value) AS ct_count
FROM reports WHERE officer=1 GROUP BY ct_value
giving results
officer ct_value ct_count
1 TSTO 2
1 DOME 1
1 ASBA 1
If you wanted to find out how many TSTO's are there for different officers you would use:
SELECT officer, ct_value, count( officer ) as ct_count FROM reports
WHERE ct_value='TSTO' GROUP BY officer
giving results
officer ct_value ct_count
1 TSTO 2
2 TSTO 1
Also any type of query for your old schema can be easily converted to new schema.
However if you need store additional information about every particular report I suggest having two tables:
Submissions
submission_id report_id ct_number ct_value
primary key
auto-increment
------------------------------------------------
1 1 CT1 TSTO
2 1 CT2 DOME
3 1 CT3 TSTO
4 1 CT4 ASBA
5 2 CT1 DOME
6 2 CT2 TSTO
with report_id pointing to a record in another table with as many columns as you need for additional data:
Reports
report_id officer date some_other_data
primary key
auto-increment
--------------------------------------------------------------------
1 1 2011-04-29 11:28:15 Everything went ok
2 2 2011-04-29 14:01:00 There were troubles
Example:
How many TSTO's are there for different officers:
SELECT r.officer, s.ct_value, count( officer ) as ct_count
FROM submissions s JOIN reports r ON s.report_id = r.report_id
WHERE s.ct_value='TSTO'
GROUP BY r.officer
