Comparing Two Sets Of Data
Jul 23, 2005
I have the following situation. One set of data has 274 rows (set2)
and anther has 264 (set1). Both data sets are similar in structure as
well as values for both of them were extracts from the same parent
table. Hope the info would substitute DDL. I need to find the "gap"
rows between these two sets.
Attempted to run a query like
select count(*)
from set2
where not exists
(select *
from set1)
did not yield what I desired. What else to try?
TIA.

Hi all,
I have two tables - Planning and Appointments:
Planning - contains a list of planned items. Used to define boundaries for a work day and defines based on type what can be done for each item.
Id,
TypeId - the type of the planned items
BeginTime DateTime - begin date and time of the planned item
EndTime DateTime - end date and time for the planned item
In the Planning table we can have as many records per day as we need:
1, First Meeting, 1 Jan 2008 09:00, 1 Jan 2008 11:00
2, First Meeting, 1 Jan 2008 11:00, 1 Jan 2008 12:00
3, First Meeting, 1 Jan 2008 13:00, 1 Jan 2008 15:00
4, First Meeting, 1 Jan 2008 15:00, 1 Jan 2008 18:00
Appointments - contanis a list with appointments
Id,
BeginTime DateTime
EndTime DateTime
1, 1 Jan 2008 09:00, 1 Jan 2008 09:30
2, 1 Jan 2008 10:00, 1 Jan 2008 11:00
3, 1 Jan 2008 11:00, 1 Jan 2008 11:30
4, 1 Jan 2008 14:00, 1 Jan 2008 15:30
What is needed?
What I need is to a find a way to compare the planned items with the appointments and to return all the periods for which a planned time exists:
Free planned time:
1, 1 Jan 2008 09:30, 1 Jan 2008 10:00
2, 1 Jan 2008 11:30, 1 Jan 2008 12:00
3, 1 Jan 2008 13:00, 1 Jan 2008 14:00
4, 1 Jan 2008 15:30, 1 Jan 2008 18:00
So, having two multitudes of periods,where the one specifies the planning templates and the other real used time, I need to find all the periods which can be used for another appointments.
I've tried several aproaches, but I always faced performance problems.
Thanks in advance.

I'm currently working on a BI architecture for a customer, and consider to propose the Power BI data catalog as a data distribution layer. The customer will use Power BI, but also has other BI tools.
Are data sets in the data catalog available to other clients than Power Query alone? E.g. are there OData feed endpoints available? If not, what would be the best way to give other tools access to the data?

Hi, I was wondering how it is posible to join three data sets from different data flows into one txt file.
Let's explain a little more:
I have 3 dataflows. Each of them connect to sql server and and by a SQL command, they bring data into SSIS.
Each SQL command differ between them. So each data set have different columns (they dont have the same format). Also the amount of columns differ between each one.
What I need is to join the three data sets into one txt file. How can I do this? It is posible to join them with different data set formats into a txt file?
Is this the best way to join different data? It is better to use as many OLE DB Sources are needed instead of different data flows?
Thanks for your help!

LASTMONTH.LAST_MONTH,(SELECT SUM(CHARGE_AMOUNT) AS LAST_MONTH

Hi All,
I would like to match two sets of data. I have setup a view of data that contains a group of customers and their details. I want to view this data, but also find these customers in another table based on matching their surname and date of birth, then retreive the information stored on these customers from the second table.
Does anyone have any suggestions how i would go about doing this?
Thanks in advance

Is there a way to put more then one data set in a list.
I have a report that has three data sets with three tables. Now i want to show each report by Region, per page. So you can view the same stuff for each region seperately, instead of all together. Is there a way to do this. Where i dont have to go back in my code, and find a way to link everything together, so its in one data set .

Hello,
I am using existing code, which I am trying to convert from using MS Access to SQL Server 2005...
The data set works fine with MS Access database, however when executing with SQL Server 2005 as data source, it generates the following error:
"..The data types ntext and nvarchar are incompatible in the equal to operator..."
in this line:
count = adapter.Update(dataset);
Not sure what should I look for since data sets are new to me.. Where should I check to fix this problem? I have noticed that the table has two columns with nvarchar...

I have two queries that generate two different datasets. One is a count of memebers, and the other is count of admits. I need to generate a calculated field from the two data sets called admits per 1000, which is essential the count of admits/counts of members *12000 I was able to calculte admits per 1000 easily in excel, however I need some insight on how to do is SQL.
Below are my queries from the two datasets.
MemberMonths dataset:
Select
factMembership.BusinessUnitCode,
EffectiveCCYYMM,
ISNULL(count(Distinct MemberId),0) As MemberCount
From factMembership
[Code] ....
Admits dataset:
SELECT
Factadmissions.BusinessUnitCode,
factAdmissions.AdmitCCYYMM,
ISNULL(Count(AdmitNum),0)As [Count of Admits]

I have a situation where i have a transactional fact table which consists of date, row type, order number and value. Â Simple example below
Date, RowType, OrderNo, Value
01-May, New, A1, 100
01-Jun, Change, A1, -10
01-Jul, Invoiced, A1, -90
What I need to be able to do is somehow select based on a day, the total value of open orders. Â I have tried to do this in the database but it becomes fixed and quite cumbersome (this is a simplified example in reality i have line information and line component information).I am not hugely skilled with MDX and SSAS but know there are some semi-additive functions i want somebody to be able to pick a day and have the total value of only open orders.

Hello and thanks in advance.
I was wondering if anyone has ever written a chart with multiple datasets.
I need to be able to show sales dollars inflow by order date on one line and on the other needs to be sales dollars delivered by delivery date. So the all sections Values, Category groups, and Series Groups in the chart will be from 2 different datasets.
I have tried but it will not allow aggreates in the series groups.
Any Ideas would be greatly appreciated.
Thanks, Leo

I am trying to build various reports that compares data over time. I have one that measures Year Over Year % difference for number of incoming projects. I managed to do that easily by calculating the following
YTDProjects:=if(ISBLANK(SUM('TrendData'[Projects])),blank(),CALCULATE(SUM('TrendData '[Projects]),DATESYTD(CalendarDate[FullDate])))
PYProjects:=if(ISBLANK(SUM('TrendData'[Projects])),blank(),CALCULATE(sum('TrendData '[Projects]),SAMEPERIODLASTYEAR(DATESYTD(CalendarDate[FullDate]))))
YoYDifference:=[YTDProjects]-[PYProjects]
YoYPercProjects:=IF([PYProjects]=0, BLANK(), [YoYDifference]/[PYProjects])
Where Projects is the metric in question, TrendData is the table that contains project data and CalendateDate is the Date Table. But now I am trying to compare the same YTD projects data to number of projects that came in the last 6 months. How do our projects compare to average number of projects that came in last 6 month period.
I tried the the DATEADD function instead but got no luck and data came out wrong!
PrevProjects:=CALCULATE(SUM([Projects]),DATEADD(CalendarDate[FullDate],-1,QUARTER))
For some reason, this also returns blank in my model:
QTDProjects:=TOTALQTD(SUM('TrendData'[Projects]),CalendarDate[FullDate])

Hi there everyone. I have a stored procedure called “PagingTable� that I use for performing searches and specifying how many results to show per ‘page’ and which page I want to see. This allows me to do my paging on the server-side (the database tier) and only the results that actually get shown on the webpage fly across from my database server to my web server. The code might look something like this:
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
The problem is the stored procedure actually returns two result sets. The first result set contains information regarding the total number of results founds, the number of pages and the current page. The second result set contains the data to be shown (the columns specified). In ‘classic’ ASP I did this like this.
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
I am trying to do this now in ASP.NET 2.0 using the datasource control and the repeater control. Any idea how I can accomplish two things:
A) Bind the repeater control to the second resultset
B) Build a “pager� of some sort using the values from the first resultset

Hi all,
I am using SSAS 2005. The mining model works fine. But it crashes when I run the 'Mining Model Predictions' against large data sets.
I ran it against 5,000,000 records and it went fine.
But exactly same model failed for 5,100,000 records and beyound.
The message is 'Query Execution Failed' and then Visual Studio crashes.
Pl. let me know if anybody has the same experience or knows the solution.

Hello,
I am looking for some "best practice" information on how to properly setup a comparison of SQL data -vs- an Excel spreadsheet. I've never performed this task before, and will likely have to do more in the future. How can I define the range of cells to be used from the xls? There are over 1000 rows in the xls, so a Select * from dbo.table where dbo.column = 'x' just isn't practical.
Any information/direction that's out there is most appreciated!
Many thanks

Hello,
I need to do a query to compare the same field in two different databases. How can I go about doing that? Can you use an if not exists and how does that work?
I also need to compare two numbers in two different databases and then convert that number to a decimal. For example I need to compare 22940 in one column and 22942 in a different column and insert the value of 2.1 in a third column. How can that be done?
Thanks in advance,
Anita

Is there a way of comparing the data contained in two separate databases (on the same server)?
I have two databases: DevDB and DB and all I want to verify is that the data in both are *exactly* the same.
Is there a nifty function to do this in SQL Server?

Hi
I am relatively new to SQL. Basically i am trying to compare data that doesn't match properly. Firstly one set of data has spaces, secondly the first part of the data is missing.
After researching I am going to remove the spaces with the replace and only query the final 8 number - this would dow hat I want but I cannot get it to work.
Here is my code.
Code:
update aleads as a, leads as l
set a.lid = l.lid
where replace(right(a.htel,8), ' ', '') = replace(right(l.htel,8), ' ', '');
Of course this didn't work but I do not know why - or how to actually achieve this.
