Hello.
I hope to explain myself well - I want to make a matrix with two rows.
Lats say my data is this:
I hava a list of months and in every month I have a number of pepole and there age.
How can I show this in a matrix?
It need to be in a matrix since I need the columns to expand acording to the month but I don't know how to create two diffrent rows in my matrix.
The data should look like this:
10/06 11/06 12/06 01/07 02/07 03/7 04/07 .....
num 5 1 2 5 4 5 7 .....
age 16.1 25 18.5 14.8 25.5 20.5 18.5 .....
Thanks for any help.

Hello:
I've created a simple greenbar matrix using the tips suggested by Chris Hays. In Visual Studio the row totals display with the correct alternating background color, but when viewing the report via the web, the report does not render any background color for the totals?
I've attached a rough example (I trimmed out a couple of colums, so don't try to add up the column values displayed with the total value). As you can see, the values for the Total column do not get shaded, even though in VS2005 it shows the Total column shading the rows correctly.

I know how to explicitly set the various properties of the totals value field (i.e, click on the little green triangle to set the properties of totals), but I can't figure out how to make it dynamic. Trying to reference ReportItems!ColorTextbox.value generates scope error.s
Thanks in advance for help on this one.

Hi
I have a report that calculates shipping quantities based on customer orders, and color codes them based on whether or not we have stock for a full shipment (green), have partial stock for a shipment (blue), or if we have none (red). Every week we get customer orders and build accordingly.
I have this all worked out except for parts with multiple ship to locations. RS seems to parse the entire row of the first ShipTo, then the second ShipTo. I'm using the running total function to calculate if there is a need or not. Anybody have any ideas?
Here is an example of the output I am getting. On the 17th, the 360 should be in green not red. I double checked the grouping, and it is on part number. This is for a matrix.

Hi,
I created a CLR UDF that returns a large number of rows, when I run it from my VPC (XP, SQL Server Developer Edition and 1GB Memory) it takes approx 2 min and 30 secs to start displaying the rows (Using Management Studio), when I run the same query in our development server (Win 2003, SQL Server Enterprise Edition, 8 GB Memory and 8 Processors) it takes more than 15 min to start displaying the results, does anybody have an idea why is this happening?
Thanks in advance

I am trying to write a query to calculate the running difference between data on different dates. Below is what my table of data looks like. Basically I want to calculate the difference between the total_completed for each state and date.
DateStatesTotal_Completed
08/27/15CA 19,952
09/11/15CA 26,336
10/02/15CA 35,444
10/08/15CA 38,278
08/27/15CO2797
09/11/15CO3264
10/02/15CO4270
10/08/15CO4297
below is what I am trying to achieve:
DateStatesTotal_CompletedCompleted_Difference
08/27/15CA 19,952 0
09/11/15CA 26,336 6,384
10/02/15CA 35,444 9,108
10/08/15CA 38,278 2,834

09/11/15CO3264467
10/02/15CO42701,006
10/08/15CO429727
below is my code (I almost have what I need) I just can't figure out how show 0 as the completed_difference for the first Date for each state since there is no prior date to calculate against.
MRR_TOTALS_WEEK_OVER_WEEK AS
(
SELECT
T1.[Date]
,T1.States
,T2.Total_Completed
,ROW_NUMBER() OVER(PARTITION BY T1.States ORDER BY T1.States,T1.[Date]) AS ORDERING
FROM TOTAL_CHARTS T1
LEFT JOIN TOTAL_COMPLETED T2 ON T1.[Date] = T2.[Date] AND T1.States = T2.States
)

I encountered a tricky problem. The original data, say, table_o, is shown below:
IdsStatusDate
ID1402-May-13
ID1310-May-13
ID1216-May-13
ID1120-May-13
ID2308-May-13
ID2210-May-13
ID2119-May-13
The final resulting table, e.g., table_f, is:
Ids4->3 3->2 2->1
ID18 6 4
ID2NULL 2 9
The values in the final table are the days used by each ID transferring from status i to status i-1. E.g., ID uses 8 days (10-May-13 - 2-May-13) to go to status 3 from status 4.
It is hard for me to come up with a table like the final table, although I know that the difference between two adjacent rows can be computed by using self-join and timediff().

On the report I have used the grouped by clause on 'Issue Reference #'. I want one more column which would calculate the difference between two consecutive Activity Date/Time of the same reference #.
e.g. Time difference between 4521404 and 4521405, 4521405 and 4521406, 4521406 and 4521473 etc. Please note that the difference between 4521412 and 4522575 will NOT be calculated since they are from different Reference Numbers.
Thanks,

Hi all,
I have a table named Orders and this table has two relevant fields: CustomerId and OrderDate. I am trying to construct a query that will give me the difference, in days, between each customer's order so that the results would be something like: (using Northwind as the example)
...
ALFKI 25/08/1997 03/10/1997 39
ALFKI 03/10/1997 13/10/1997 10
ALFKI 13/10/1997 15/01/1998 94
ALFKI 15/01/1998 16/03/1998 60
ALFKI 16/03/1998 09/04/1998 24
...
At the moment, I have the following query that I think is on the right track:
€¦
SELECT dbo.Orders.CustomerID, dbo.Orders.OrderDate AS LowDate, Orders_1.OrderDate AS HighDate, DATEDIFF([day], dbo.Orders.OrderDate, Orders_1.OrderDate) AS Difference FROM dbo.Orders INNER JOIN dbo.Orders Orders_1 ON dbo.Orders.CustomerID = Orders_1.CustomerID AND dbo.Orders.OrderDate < Orders_1.OrderDate GROUP BY dbo.Orders.CustomerID, dbo.Orders.OrderDate, Orders_1.OrderDate, DATEDIFF([day], dbo.Orders.OrderDate, Orders_1.OrderDate) ORDER BY dbo.Orders.CustomerID, dbo.Orders.OrderDate, Orders_1.OrderDate
€¦
However, this gives me too much data:
€¦
ALFKI 25/08/1997 03/10/1997 39
ALFKI 25/08/1997 13/10/1997 49
ALFKI 25/08/1997 15/01/1998 143
ALFKI 25/08/1997 16/03/1998 203
ALFKI 25/08/1997 09/04/1998 227
ALFKI 03/10/1997 13/10/1997 10
ALFKI 03/10/1997 15/01/1998 104
ALFKI 03/10/1997 16/03/1998 164
ALFKI 03/10/1997 09/04/1998 188
ALFKI 13/10/1997 15/01/1998 94
ALFKI 13/10/1997 16/03/1998 154
ALFKI 13/10/1997 09/04/1998 178
ALFKI 15/01/1998 16/03/1998 60
ALFKI 15/01/1998 09/04/1998 84
€¦
So, do any of you have any ideas how I might achieve this? I know how to do it using a stored procedure, but I am trying to avoid that; I€™d like to do this in a single query.
Thanks for any help you have to offer,
Regards,
Stephen.

Hi,
i have a matrix, and in that matrix i need to have one column which calculates the percentage change between a value on the current row and the same value on the previous row.
Is this possible? The RunningValue() function isn't of help as it can't help me calculate the change between two rows, and Previous() doesn't work in a matrix (why???!!!!!). Also calculating this as part of the query isn't possible as there is a single row group on the matrix, and the query is MDX.*
Thanks,
sluggy
*for those who are curious, the matrix is showing data an a per week basis, the row group is snapshot date, i am trying to measure the change in sales at each snapshot.

Hi All
I have a matrix with single row. The no. of column varies and sometimes goes to 10-15. So it goes to next page and while exporting it inserts blank pages when exported to PDF. I need the column width at least 2.5cm. I need to break the matrix to next row instead of it going to next page say after 6th or 8th column. I tried to work with the example given in the site http://blogs.msdn.com/chrishays/archive/2004/07/23/HorizontalTables.aspx by Chris Hays. But it is showing matrix for each Row Group, which doesn't meet my requirement.
I had a work around which worked by putting two matrix one below the other and filtering the columns to be shown in each matrix.
If anybody faced this issue or anybody solved the issue kindy reply which will be very helpful for me.
One more doubt, Can I get the Column number of the matrix?
Thanks in advance

how to measure a change in inventory over various stores. Â My sql2008R2 express db gets a new row of data everyday from each store(about 40 stores) for a single product stock count "OnHand" and if there is any new stock on order.

I am trying to create an exception report that will show the difference between two versions of the same row. (Combination of two different sources in sql, with source 1 having childID = 0 and the other source having childID = 1; parentID is the link between them)
The results are as follows:
ParentID - ChildID - Col1 - Col2 - Col3
1 - 0 - AA - BB - CC

Given a table that has three columns that together create a key and two columns that together define NameValue pairs, how can the difference between instances of values be calculated and displayed?One table is used to contain periodic dumps of data from various sources. Because this is an early stage of development for the software project instead of having explicit columns that contain specific data the table contains name/value pairs. This allows the software to export anything to the database table. When this data is imported, earch row shares the same key (three columns containing a machine type, serial number and a timestamp), a name that identifies the data and a string that contains the actual data. While this arrangement makes it trivial to support the addition of any data that the software developers want to export, it makes it less obvious as to how to generate reports.Let's make an example. Lets assume that there are two vending machines, each of which has just 3 snacks and each of which generates two separate reports.
Type Sn Timestamp Name Value
A 1 2015-08-15 12:34 Snick 5
A 1 2015-08-15 12:34 Mars 10
A 1 2015-08-15 12:34 MandM 0B 2 2015-08-15 15:31 Snick 1
B 2 2015-08-15 15:31 Mars 9
B 2 2015-08-15 15:31 MandM 0A 1 2015-08-21 09:12 Snick 11
A 1 2015-08-21 09:12 Mars 18
[code]...
So, the names of the values become the report's columns. The reports are sorted by timestamp, then by type, then by serial number.The value associated with the previous row that shares the same name is subtracted from the value of the next row in which the same name occurs and that becomes the displayed value in the report.

1. Is it possible to use the subtotal as a field for calculating values?
2. Can I add another row to the subtotal area, having two subtotal rows?
I need to achieve the following output:
Months
1 2 3
101200 Cust1 2008 50 40
2007 45 45
Subtotal +5 -5
102300 Cust2 2008 70 80
Subtotal 0 0
What I want is to use the subtotal as a variance-field for the two selected years by the user. It could happen that a customer doesn't generate turnover in one year, then the subtotal has to be 0 or 100 or whatever.
If my suggestions aren't applicable then I'd like to know If there is another possibility to display the desired results.
Thanks!

I have a table and matrix placed next to each other in my report:
[Table displaying ProjectInfo, Revenue, etc.. ][Matrix displaying Monthly Distribution]
When I run the report, the result set returns say 100 rows for table and a row for each project in Matrix. The header and detail rows of table and matrix are perfectly aligned with each other, however, on the first page the table displays 47 rows and then breaks while the matrix displays 50 and breaks. On the next page the Matrix is three rows shorter. As a result the bottom of each control does not align on any page.
Any ideas what could be going wrong or how to fix this?
Thanks.

I just spent about 30mins searching through the forums for this and saw several posts, but I didn't find a straight answer that seems like it would work for my report. How can I add only 2 data rows to a group (to hide them via the group's visible properties) and keep the rest of the rows outside of the group, but still in the same column (vertical area), as shown:
This is the view of all rows:
Cat1
Cat2
Product A
Data 1
#
#
Data 2
#
#
Data 3
#
#
Data 4
#
#
Data 5
#
#
Data 6
#
#
Product B
Data 1
#
#
Data 2
#
#
Data 3
#
#
Data 4
#
#
Data 5
#
#
Data 6
#
#
And this is the view I'm seeking in some cases:
Cat1
Cat2
Product A
Data 1
#
#
Data 4
#
#
Data 5
#
#
Data 6
#
#
Product B
Data 1
#
#
Data 4
#
#
Data 5
#
#
Data 6
#

I have found execution plan with significant difference between actual and estimated number of rows (roughly actual/2=estimated) in non-clustered index seek.Statistics are updated.

I have a table like this.
CREATE TABLE Table1
([S_ID] varchar(7), [S_ACTV_CODE] varchar(4), [S_USER] varchar(5), [S_DATETIME] varchar(19), [S_ACT_IND] int)
;
INSERT INTO Table1
([S_ID], [S_ACTV_CODE], [S_USER], [S_DATETIME], [S_ACT_IND])
VALUES
('AAA-111', NULL, 'USER1', '2015-06-15 00:21:06', 0),
('AAA-111', '2', 'USER1', '2015-06-15 00:21:07', 0),
[code]....
Basically I want to calculate the time spent by S_Users on a particular S_ACTV_CODE:
- S_ACTV_CODE_PREV means the previous active records.
- S_START_TIME is the time of S_DATETIME when a S_ACTV_CODE starts
- S_END_TIME is the time before a S_ACTV_CODE changes to another S_ACTV_CODE
- For the first record, S_ACTV_CODE is null, so there is no S_ACTV_CODE_PREV, so S_ACTV_CODE_PREV is NULL
- For the second record S_ACTV_CODE has some value, but S_ACTV_CODE_PREV is NULL for first record. So second record S_ACTV_CODE_PREV is also NULL
- For the last record (means S_ACTV_IND = 1), the user is currently working on it and S_ACTV_CODE is not changed. So S_END_TIME is a open time and we want to keep it as NULL
So the result should be as below:
S_ID S_ACTV_CODE_PREV S_ACTV_CODE_CURR S_USER S_START_TIME
S_END_TIME TIME_SPENT (in Sec)
AAA-111 NULL NULL USER1 2015-06-15 00:21:06
2015-06-15 00:21:07 1
AAA-111 NULL 2 USER1 2015-06-15 00:21:07
2015-06-17 03:20:33 183566
AAA-111 2 4 USER2 2015-06-17 03:20:33
[code]....

There is a stored procedure. It uses linked server. As we will be migrating to amazon cloud, our architect instructed not to replace linked server with openquery.
