In my cube there are two measures which are used in different calculations.Now I'm need to show in report if there any months in data when both or even another one of the measures is not updated (value = 0 or NULL).
how should I create the calculated measure for that?
I have tried in mgmt studio to plan this but I'm in a loop of errors.
Hi,
I am wondering how to create a matrix that contains 1 dimension for Top Label (Column), let's say "Year-Month"
and then 2 Measure to be in the row format rather than columnar format.
Example as below :
Year-Month on the column, and the measure is on the row :
2007-04
2007-05
2007-06
Amount Sales
1000
2000
3000
Unit Sales
10
20
30
Total
1010
2020
3030
Please share with me if you have this solution in Reporting services as it works in excel, hyperion brio, bo, cognos but somehow cannot see that function in Reporting Services.
Thanks

In SSAS, I want to add a calculated measure and set that measure as the Parent of existing measure. For example I have the measures as A and B from the fact table. Now i want to add a calculated measure as C and set this measure as Parent for measures A and B. How to do that in SSAS.
View 4 Replies View RelatedI want to filter a measure based on another measure (both are measures on the same FACT table).Distinct Number of Users HAVING.User Cost above 0.
I tried doing having but because it’s two measures and not a tuple with a dimension it writes an eror.My query is something like:
SELECT
 [Measures].[Distinct Number of Users ]
having [Measures].[User Cost] >0
 ON
COLUMNS,
[code]....

Please note, that I want it in a MDX query not needing to change the cube or DWH table.
So far we are happy with MS OLAP 2000 service.
In the past we did cubes with aggregation method using summary.
MS OLAP server allows aggregate functions (Sum, Min, Max, Count, and Distinct Count).
But now the customer wants to know percentage of SUM(measure A) /SUM (measure B) in different levels and dimension combination.
Any idea?
What does 'tablename. index... cost: 100%' mean when I use display estimated execution plan?
View 1 Replies View RelatedI have a stored procedure that will execute with less than 1,000 reads onetime (with a specified set of parameters), then with a different set ofparameters the procedure executes with close to 500,000 reads (according toProfiler).In comparing the execution plans, they are the same, except for the actualand estimated number of rows. When the proc runs with parameters that producereads that are less than 1,000 the actual and estimated number of rows equal1. When the proc runs with parameters that produce reads are near 500,000 theactual rows are approximately 85,000 and the estimated rows equal 1.Then I run:DBCC DROPCLEANBUFFERSDBCC FREEPROCCACHEIf I then reverse the order of execution by executing the procedure thatinitially executes with close to 500,000 reads first, the reads drop to lessthan 2,000. The execution plan shows the acutual number of rows equal to 1,and the estimated rows equal to 2.27. Then when I run the procedure thatinitially executed with less than 1,000 reads, it continues to run at lessthan 1,000 reads, and the actual number of rows is equal to 1 and theestimated rows equal to 2.27. When run in this order, there is consistency inthe actual and estimated number of rows and the reads for both executionswith differing parameters are within reason.Do I need to run DBCC DROPCLEANBUFFERS and DBCC FREEPROCCACHE on productionand then ensure that the procedure that ran close to 500,000 reads is runfirst to ensure the proper plan, as well as using a KEEP PLAN option? Or,what other options might you recommend?I am running SQL 2000 SP4.--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200609/1

Hi,
I am writing a client application that shows estimated queries plans and statistics. I know how to obtain estimated plans by using SQL Server Management Studio. But is it possible to obtain by using database functions?
I have found sys.dm_exec_query_plan, but it seems that this function can only be used for executed (or executing) queries...
Thanks
Hello,
i am making a Fulltextsearch on MS SQL Server 2005 (indexed, with "Contains").
Because of performance reasons i am only showing the first 200 rows mssql finds ("select top 200...:").
Is there any possibility to get the estimated totalnumber of all rows? i have heard something that is possible to get this in mssql-server. The server then estimates how many rows with that searchword could be in the whole database. google i.e. makes the same thing....
is that true? what do i have to do to get this?
greetings and thx

I am running an update query.It is taking long time. To find the estimated completion time i checked sys.dm_exec_request or sys.dm_exec_session or sp_who2 but there is no clue. It is showing as zero.
View 3 Replies View RelatedWhat's the use of display estimated execution plan....
View 4 Replies View RelatedWhen I generate an estimated execution plan from Management Studio, one of the things I often see in the execution plan generated is an 'Index Scan'. When I put my mouse over the 'Index Scan' graphic, I will see a window display with something called 'Output List' at the bottom of the window. Do I understand correctly that SQL Server will scan my index looking for values in each of the fields included in this output list?
Thanks, Amos.

Hi,
I used to use a insert subselect on the 6.5 catalog table
How to calculate estimated completion time of a job and what is the variance/difference in time based on previous job history. Looking for tsql query which can accomplish this.For example)...Daily a job is taking 10 mins to complete. However, today due to some reason, the job is running over an hour and still running. It could be a blocking issue or some performance issue on the server due to which the job is still running.
In such cases, using a tsql query or a stored proc which monitor these jobs every 3 mins (Configurable value), so every 3 mins , query has to check, if they are any jobs which are taking more time than its usual completion time/avg completion time in that case shoot an email using dbmail functionality i.e. sp_Senddbmail .. From there, DBA can dig further using waits or sql trace etc...
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.

View 8 Replies View RelatedHi all,
Sometimes when I do "alter database ABCD set partner failover" I get the following message: Nonqualified transactions are being rolled back. Estimated rollback completion: 100%.
In 99 percent of the cases after such message the first attempt to use an open connection would also raise an error such as "Exception: A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)"
After the first error all subsequent queries would run perfectly.
What am I missing?

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?
Hi,
easy question for advanced users:
I have a dimension called "Movement rate". The members are "1" to "6".
There is a measure called "No. of Products".
What i easily like to do is showing the percentages "No. of Product" for each "Movement rate" of the amount of "No. of Products" without using the frontend-tool.
Thx in advance for any help.

There is count measure in the cube. I need to create a dimension that should list the range of values based on that count values:
Exp:
0-99
100-199
200-399
...
....
..
and so on.
User wants to pick the any range level in the dimension and cube should show corresponding cell values of count measure which would fall into range of the dimension level value.
For example:
if user picks up level 100-199 then cube would filter cell values of measure that has a value between 100 and 199 within 12 month range. So, it would be year to date value of the measure. My problem is how go about creating Dimension that based on measure in the cube and dimension should have level with range of measure values.
Any hint would be appreciated greatly.
Thank You.
HI all friends
I have a Fact table like this
DIMENSSIONSMEASURES
------------------------------
idempidprodcutsalessalesws
I just want make the next query with MDX
SELECT sales

How it would be in MDX? I need a lot of help

Hi,
for a calculated measure I need the total sum of a measure in different dimension. So for example I want to get in my first dimesion 1500 as my sum and in my second dimension too. Is there a way to get it?
(FirstDimension.CurrentMember.Parent, [Measures].myMeasure) doesn´t work!
Best regards,

Hi,
I am newbie in Analysis services. My problem is that I have to show a yearly report for credit expiry. In my fact table the measure is credit rate.
I have attributes of start_day_key and end_day_key. Now when I go through analysis services it does not let me create a measure so that I can count end_day_key for a year (end_day_key is linked to day table with daykey. It has date) and show. The thing is the measure I want is not stored (i.e: the count of end days for a year ). How do I go about it?
Should I create a calculated cell? (I tried that, but mdx does not work)
I used : Count({[Measures].[End Key]})< 366
Now this is not wha I want, I want the end_key count by matching date in day dimension for the current year? Any help is greatly appreciated.

I have a delima.
I have a dataset that needs to return "Fatalities Involving drivers age 15-17". For years 2003 , 2004, 2005.
So i set up 3 different filters: Year : 2003,2004,2005
Person type: Driver
Age : 15,16,17
Now this is fine for getting a crash count and fatalities (for teen drivers). But i want the fatalities for everyone ( All Person Types) and (All Ages) ...how do i go about this. All i get right now, is the fatalities for Drivers 15-17.
Please help..im confused!
I need to create one or two tables in the database. There are a few ways I can design these tables, so I€™d like to measure data loading performance. My primary concern is level of IO generated by SELECT. I don€™t expect CPU utilization to have any meaningful impact, but it would be nice to know how to measure processor utilization as well.
PerformanceMonitor application is not really an option, because it measures IO and CPU at SQL Server process level.
My development box is not going to match production boxes, so I would like to measure IO in terms of amount of data loaded from disks instead of timing stored procedure execution. The same is true for stored procedure CPU utilization.
It is my understanding that SQL Server keeps table content loaded in memory as much as possible to improve performance. How do I negate effect of caching on my IO numbers?
I have created a table in the sql server 7.0 and I wanted to know the what is the size of the table, is there any storeprocedure or command that can be used to measure the space used by the table in the database
View 2 Replies View RelatedI need to build a cube for membership over time. Active membership is the gap from the record's CreationDate to SuspendedDate, as compared to a reference date (today's active members have CreationDates before today, and SuspendedDates > today, or NULL).
Any idea how to build a cube so I can count membership over a Time dimension? The only approach I've been able to come up with is to create a table with a record for each active member on each date (brute force).

Hello
I am a newbye with Analysis Services and am desperately trying to find a way to include a calculation between one of my measures (Teus), divided by the vessel capacity, where vessel is one of my dimensions (and is therefore not depended on other dimensions...)
Any ideas how I could implement that ?? This would help a lot, thanks for your help,

Hello,
I have a Sales cube and I want to be able to display Products and the
Price at which they were purchased in a given period. I have a
Product dimension while Price is a measure in my Sales Fact Table. Is there a way to have a "Group By" aggregation instead of a Sum? This way, I can show Products grouped by their list price.
My Product Dimension consists of product_numbers (such as 100, 101,
102 etc...)
My Sales Fact Table consists of sales data (such as product_key,
price, net_sales, returns, etc...) at the transaction level.
I want to be able to view the data like this:
Price Net_sales Returns
Product
100 $5.99 $2005 $320
101 $3.51 $7110 $998
where Net_sales and Returns are "summed" and Price is simply a "Group
By". In other words, this report would show the net sales and returns
by product for a given price.
I'd rather not use a Price dimension since we have hundreds of
products at hundreds of different prices. Moreover, this data is
already in the Sales Fact table.
Thanks for any help provided
