Generating Data In An Order Per Data Row
Dec 7, 2007
Title is probably poorly worded
Say I have a table setup like this:
Code:
AccountID | GeneratedDesc | Col1 | Col2 | Col3 | Order
-------------------------------------------
1|| Data1 | Data2 | Data3 | 1,2,3
2|| Data1 | Data2 | Data3 | 1,3,2
3|| Data1 | Data2 | Data3 | 2,3,1
1|| Data1 | Data2 | Data3 | 1,2,3
Basically, I want to set GeneratedDesc = Data1 + ' ' + Data2 + ' ' + Data3 where an account sets the order 1,2,3
GeneratedDesc = Data2 + ' ' + Data3 + ' ' + Data1 where an account sets the order 2,3,1
Basically, The Generated Description is set in an order that is chosen by the Account.
I am not sure how to go about doing this, outside of dynamically generating the query and looping throughout all the rows in the table, which, i think for large amounts of data, can get expensive. I don't think creating a query for each combination would be good either (in this case, 6 combinations, but for larger order sets, such as 6, can get quite alot of queries).
any ideas? (not sure if this makes sense to anyone)

I am using the following query to export data from sql server to ms access in export data wizard:
SELECT * FROM myView where myID = 123
Order by varcharColumnName1,varcharColumnName2 ,intColumnName3
This query will fetch about 7, 00,000 records.
SQL server 2005 shows the correct order, but Data in access table shows Incorrect data.
Please give me the solutions.

I never paid much attention to this before but I noticed this today in a new table I was creating.
For tables defined in the tabular model the table properties have something like SELECT Blah FROM TableName ORDER BY Blah Then in the tabular model the table's data is in the same order it was ordered by in the data source for the table.
I have a date table I setup and I noticed it is NOT respecting the sort order.
I have it sorted by DateID which sorts with the oldest date first and newest date as last row.However, the table that is imported and stored in the data model is not in that order.
I can of course manually sort the rows in BIDS/DataTools, but I find this discrepancy odd.
Would this have negative impacts on the EARLIER function for example if the data rows are not in the order specified?

Hi,
I use SQL Server 2005 Dev Edition and am not new to making databases (then again, I've had enough experience and my dad does the same thing).
I am (unfortunately) a university student and for my dissertation I am going to produce a SQL Server database with a strong emphasis on data mining.
Obviously, for the data mining to be useful at all I need to produce loads and loads of test data.
Fair enough, and there are applications which do this, such as EMS Data Gen, but can anyone recommend me any other data gen utilities? EMS Data Gen has poor handling of unique attributes, and as I am doing a car manufacturer this will give me problems when I come to the registration number attribute.
Also, why are utilities for SQL Server (and Oracle at that) so expensive? This makes it out of my reach and makes it difficult to build a truly good database that will net me good marks, and demotivates me. :(
Lastly, please feel free to recommend to me any utilities for SQL Server - such as performance monitors, backup utilities. Anything. But if they are priced utilities, they have to be sensibly priced (<£100), because I cannot yet afford to pay >£1k on such utiltiies.
Thanks

Sorry about the huge post, but I think this is the amount ofinformation necessary for someone to help me with a good answer.I'm writing a statistical analysis program in ASP.net and MSSQL7 thatanalyzes data that I've collected from my business's webpage and thehits it's collecting from the various pay-per-click (PPC) engines.I've arrived at problems writing a SQL call to generate certainstatistics.Whenever someone enters our site from one of the PPC search engines, Iwrite out a row to the Hits table. In that table are the followingcolumns:HitID - the Unique ID assigned to each hit that comes into the siteKeyword - the keyword the user searched on when he or she came to thesiteSearchEngine - the PPC engine the user came fromSource - this is pretty much always 'PPC'...if we were to do otherthings, like a newsletter, then this would be different.TimeArrived - the date and time the user arrived at the website. Ihave no idea why I didn't call it "datearrived," since I use "date"and not "time" pretty much everywhere else...(I don't think the rest are important, but they might be, so I'llinclude them for completeness's sake)Referring URL - the URL the user came fromReferring Website - the string between the 'http://' and the first '/'in the URL. I know it's redundant information, but when I designedthis part, I didn't know how to parse it out afterwards, so I justfigured I'd duplicate it.Page Visited - the page the user first arrived atWhen a person comes to the site, I also write out a session cookiecontaining the user's hitID. If the person fills out an enrollmentform (a process which we refer to as "responding"), I attach thatsession ID to the form. The response form (and thus the responsestable) is long; these are the important fields:id - a unique ID for each responsedate - the date and time of the responsestatus - a varchar field containing a status code. I would have madeit a number, but I wanted it to be viewable from looking at the rawdatabase.hitid - the HitID of the user, taken from the session cookie. If thereis no session cookie (for whatever reason), the HidID is written outas 0. While it wouldn't occur often, I can't guarantee that there willnever be more than one response record attached to a singular hitid.Later, some of the responses turn into "confirmations", which meansthat they've actually ordered from us, not just filled out the form.This usually happens about three or four days after the initialresponse. When this happens, the status of the response is changed toa phrase containing the word "confirm" in it (there are a few of them,but they all contain that word).So now that we've collected all this marketing intel., I need toanalyze it.I've written a parser that takes reports from various pay-per-clickcompanies and puts them into a table called PPC. Information in thiscolumn is written out as one record per search engine per keyword perday. The schema is as follows:id - a unique ID for the record in the tabledate - the date to which the information in the record appliessearchengine - the PPC engine to which the information applieskeyword - the keyword to which the information appliesclicks - the number of clicks on the applicable keyword on theapplicable search engine on the applicable day.impressions - same as clicks, but for impressionscpc - the cost per click on the applicable keyword ...avgpos - (I don't always have a value for this field) The averageposition that the keyword was shown in for the applicable keyword ...With this data in, the last step is actually analyzing the threetables for useful statistics on the various keywords, search engines,and time frames. That's the step I've been trying to complete.So what I need is a SQL call that I can run that generates a tablewith the following information:SearchEngineKeywordCost / Click - When calculating the CPC, I can't just take an averageof all the records. I need to calculate the total amount spent per day(clicks * cpc), add that up for every day, and then divide that by thenumber of total clicks. Just doing an average doesn't take intoaccount the fact that some days we'll get more clicks than others.Total Spent - # Clicks * CPC#Responses - counting the number of records in the responses table#Confirms - counting the number of records in the responses table with"confirm" in their statusTotal Spent / #ResponsesTotal Spent / #ConfirmsOh yeah, and I want to be able to order by any four of the fields inany order, narrow my selection to only those keywords that either areor contain a user-specified string, further narrow my selection toonly those records that fit other user-specified criteria for any ofthe columns in the table I'm generating, and select only the top xrecords (where x is a user-specified number). I already haveuser-controls that output the SQL for all of these things, but I needto have places in which I may put that SQL in my call.After many trials and tribulations, I've come up with the followingSQL call. Right now, its output for nearly every row is incorrect, Ithink in a large part due to the fact that the method that I'm usingto generate the number of clicks is yielding incorrect values.If you'd like to help me and you think that modifying the followingcall is easier than writing a whole new one, be my guest; if you'dprefer to write a new one, I'm game for that, too. I'm just concernedwith its working right now, and any help you can give me is greatlyappreciated.Anyway, here's the call:/*sp_dboption @dbname='NDP', @optname='Select Into', @optvalue=true;*//*Running the above might be necessary to get the "Select Into"s towork*/Drop table ResponsesPPCDrop table ConfirmPPCDrop table TempPPCSELECT Responses.[ID] as [ID], Responses.Status, PPC.SearchEngine,PPC.KeywordInto ResponsesPPCFROM Responses, PPCWHERE Responses.HitID IN(SELECT Hits.HitIDFROM HitsWHERE Hits.SearchEngine = PPC.SearchEngineAND Hits.Keyword = PPC.Keyword)SELECT ID, Status, SearchEngine, KeywordInto ConfirmPPCFROM ResponsesPPCWHERE Status LIKE "%confirm%"Order by SearchEngine, KeywordSELECT PPC.SearchEngine, PPC.Keyword,SUM(PPC.Clicks), /*I noticed that thiscolumn gives me incorrect values(I don't need it in my final report, but it's useful for debugging).For some keywords, it gives me huge numbers(e.g. 265 clicks on one word that got ~10 clicks /day over five days),and for others, it doesn't give me enough. I think this is a majorpartof what's throwing off the rest of the statistics*/Case SUM(PPC.Clicks) WHEN 0 THEN 0 ELSESUM(PPC.clicks * PPC.cpc) / SUM(PPC.Clicks) END as CPC,SUM(PPC.clicks * PPC.cpc) AS TotalCost,count(ResponsesPPC.ID) As NumResponses,Count(ConfirmPPC.ID) As Confirms,(Case Count(ResponsesPPC.ID) WHEN 0 THEN 0 ELSESUM(PPC.clicks * PPC.cpc) / count(ResponsesPPC.ID) END) ASCostPerResponse,(Case Count(ConfirmPPC.ID) WHEN 0 THEN 0 ELSESUM(PPC.clicks * PPC.cpc) / count(ConfirmPPC.ID) END) AsCostPerConfirmFROM (PPC LEFT JOIN ResponsesPPC ON PPC.SearchEngine =ResponsesPPC.SearchEngineAND PPC.Keyword = ResponsesPPC.Keyword)LEFT JOIN ConfirmPPC ON PPC.SearchEngine = ConfirmPPC.SearchEngineAND PPC.Keyword = ConfirmPPC.KeywordGROUP BY PPC.SearchEngine, PPC.KeywordOrder by PPC.keyword desc/*Drop table ResponsesPPCDrop table ConfirmPPCDrop table TempPPC*//*I don't drop them right now so I can look at them,but normally, one would drop those tables.*/Thanks a lot for your help,-Starwiz

I have been generating report models for users to use with Report Builder and there is no data when they select the model. I noticed that the tables I chose did not have a primary key and when I chose a different table, with a primary key, and generated a model from it, then there was data for the user to use in Report Builder.
Is there a documented work around or will I need to set a primary key on each table?

Hi,
I am attempting to explain my probelm again. Please read it:
I have 3 tables. CallDetail, Call and Request. The tables are populated in the following order: One row for CallDetail, One for Call and one for Request and so on.
I have to generate a UniqueNo - Per empid, Per StateNo, Per CityNo, Per CallType. The no will remain same for the same CallDetailID and ordered by the date created. However if the CallDetailId changes, the no. will increment based on the empid, Per StateNo, Per CityNo, Per CallType
For eg:
For Eg: ( Assume Call Detail id is changing for all the days)
Monday - 3 calls made for empid 1, state SA023, city 12 and call type 1 will generate a unique id 1 for all 3 calls
Tuesday - 2 calls made for empid 1, state SA023, city 12 and call type 1 will generate a unique id 2 for both calls
Wednesday - 3 calls made for emp id 1, state SA023, city 12 and call type 2 will generate a unique id 1 for 3 calls as the call type is different than the previous day for same employee
Thursday - 2 calls made for empid 2, state SA023, city 13 and call type 1 will generate unique id 1 for both the calls as combi of city and call type are different.
So the unique id has to be generated considering empid, state, city and call type, ordered by the EntryDt. EntryDt is needed because :
3 calls made for empid 1, state SA023, city 12 and call type 1 at 10/11/2007 10.00 AM will generate a unique id 1 for all 3 calls
2 calls made for empid 1, state SA023, city 12 and call type 1 at 10/11/2007 12.00 AM will generate a unique id 2 as the call was registered later.
Here is what I wrote with the help of a mod over here:
Code Block
DECLARE @Request TABLE(RequestID INT, CustomerName VARCHAR(30),
StateNo NVARCHAR(5), CityNo INT, CallID INT, UniqueNo INT)
INSERT @Request

66234 Mutuk SA023 12 185 2
2232362 Buck SA023 12 195 1
as the call for Buck is of calltype 3 which was not done earlier. So the no starts from 1.
Also how to add the paritioning by empid, StateNo, Per CityNo, Per CallType and yet maintain the same unique no for the same calldetailid.
Eg: CallGroup = ROW_NUMBER() OVER (PARTITION BY empid, state, city, calltype ORDER BY EntryDt )
thanks for any help.

Please note that this will not be run as a batch query, but the no. has to be generated and inserted into #record table in realtime. I have given bulk of records for understanding of the problem
Plz help. I am stuck from 2 days on this :

hi, I'm using sql server 2005 standard, and I want to be able to move my local database to another server, but I can't figure out how to script the database and the data so that I can just run one script to move the whole database. this can be done right? I can't imagine that such an obiviously necessary tool would be intentionally left out, so I'm figuring that I'm just a doofus and don't know where the option is...
can anyone help? thank you!

Is it possible to write a SP (Automate) to generate STATISTICS on any database and then use the output to create the stats on that database.
I ran the tuning adviser and it suggested indexes with lot of STATISTICS on the dev environment. This dev environment is replicated in several other environment with data size in these environment varying. I would like to know if I can create a SP which generates STATISTICS information pertaining to specific database environment for the query in question for tuning.

When I attempt to generate a datasource model I get the following error messages:
------------------------------------------------
More than one item in the Entity 'Customer' has the
name 'Customer Merge Custs'. Item names must be unique
among immediate siblings. (DuplicateItemName)
More than one Field in the Entity 'Customer' has the
name 'Customer Merge Custs'. Field names must be
unique within an Entity. (DuplicateFieldName)
More than one item in the Entity 'Pricing Service Layout
Detail' has the name 'Pricing Service
Extensions'. Item names must be unique among immediate
siblings. (DuplicateItemName)
More than one Field in the Entity 'Pricing Service Layout
Detail' has the name 'Pricing Service
Extensions'. Field names must be unique within an Entity.
(DuplicateFieldName)
---------------------------------------------------
Examining any of the above tables in SQL Server Management Studio does not reveal any duplicate column names. In fact, 'Customer_Merge_Custs' does not appear to be a column in 'Customer' nor does 'Pricing_Service_Extensions' appear in 'Pricing_Service_Layout_Detail'.
As an experiment, deleting the table 'Pricing_Service_Extensions' and regenerating did make the two associated messages go away.

We have an MIS system which has approx 100 reports. Each of thesereports can take up to several minutes to run due to the complexity ofthe queries (hundreds of lines each in most cases). Each report can berun by many users, so in effect we have a slow system.I want to seperate the complex part of the queries into a process thatis generated each night. Then the reports will only have to querypre-formatted data with minimal parameters as the hard part will havebeen completed for the users when they are not in. Ideally we willgenerate (stored procedure possibly) a set of data for each report andhold this on the server. We can then query with simpler parameterssuch as by date and get the data back quite quickly.The whole process of how we obtain the data is very complex. There arevarious views which gather data from the back office system. These arevery complex and when queries are run against them including othertables to bring in more data, it gets nicely complicated.The only problem is that the users want to have access to LIVE datafrom the back office system, specifically the Sales team who want toaccess this remotely. My method only allows for data from the nightbefore, so is there an option available to me which will allow me todo this ? The queries can't be improved on an awful lot, so they willtake as long as they take. The idea of running them once is the onlyway I can see to improve the performance in any significant way.True I could just let them carry on as they are and let them sufferwith the performance on live data, but I'd like to do something toimprove the situation for them.Any advice would be appreciated.ThanksRyan

I have a stored procedure that is pulling 3 parameters: @user_id, @, begin_date and @end_date. The parameters are setup in the 'parameters' tab of the data set, and also the 'report parameters', however, when I go to run report, I get textbox for user_id, instead of a drop down with pick list.
I tried creating a separate dataset to bring in user_id's only and manually create a parameter for it in 'report parameters'. I then get a drop down box with repeating data, and when I run the report, I get back all user_id's instead of the one I chose.
I'm finding the parameters are the most difficult concept within RS. Does anyone know I can make this work?
Thanks!

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

Hi ,
Hopw can i sort the data in the ascending order so that i can see the date of my log files imported at the top of my table .
Right now my log files get imported and appended in the tables but they get appended in the descending order at the bottom of the last data .

Many Thanks .

This query works perfectly and orders by just as I need
Code:
Select
'1st' As [Type],
#Uno.ID
#Uno.Address,
#Uno.shippingInfo
FROM #Uno
[Code] ....
However, when I use it in a Union All so I can pull data from 2 diff tables, the order by statement no longer works. How can I order by data in 2 tables?
Code:
Select
'1st' As [Type],
#Uno.ID
#Uno.Address,
#Uno.shippingInfo
FROM #Uno
[Code] ....

When We sort the data by using ORDER BY , which sorting algorithm method will be used by SQL optimizer?
1) Bubble Sort
2) Quick Sort
3) Merge Sort
4) Heap Sort
5) Insertion Sort

Hi,
A long long time ago I asked for the ability to define an order in which you insert data into multiple destinations in a single data-flow. This was to get around the problem of loading tables in the same data-flow that have FK relationships between them.
My chosen alternative at the moment is to load the table with the unique key first and drop the data for the table with the FK into a raw file and load it in a seperate data-flow. Another alternative is to disable FK constraints and reenable after but I've chosen the raw file method.
Now that I'm using SSIS on a real project this is becoming a much bigger problem that I ever envisaged it might be. Its rare that I'm building stuff where I don't have to use raw files for this very reason and this means that I have god knows how many raw files hanging around all over the place.
I suppose the reason for this post is to flag the importance of this requested feature. I really hope that this makes it into Katmai. Or into a service pack would be even better!
Its a bit of a failing at the moment.
Are there any chances that this will make it into Katmai? its one of my biggest bug-bears about SSIS v1.

Hi,
I want to ask a basic question, that is
IN WHAT ORDER A CLUSTERED INDEX SORT THE DATA IN THE COLUMN????
Somewhere in the MSDN library I read the following line:
"A clustered index physically sorts the table's contents in the order of the specified index columns"
But Sorting means it will be in ASCENDING ORDER (ASC) or It will be in DESCENDING ORDER (DESC)
So my question is lets suppose a column on which the cluistered index is defined and it contains character data liek abcd so in wht order it will sort the data alphabetically ASC or DESC
or
If the same above case with integer type of values, if column having integer values then in wht order the data in the table will be sorted.
??????
Thanks..!!!

I am querying a table with multiple rows
SELECT caseId, Name ,CompletedDate
FROM TableZ
the number of results per CaseID are varable some have 1 record others up to 36 records..I need to pivot the results based off of the competed date
Name has 20 distinct values but we can have diplicates...so something like
Case Name Date
1 This 2015-01-01
1 That 2015-01-03
2 That 2013-01-01
2 Then 2014-12-03
2 This 2015-01-01
2 There 2015-04-03
3 This 1999-01-01
3 That 2001-01-02
3 This 2006-01-01
looks like this
1 This That
2 That Then This There
3 This That This

Hi
I was going through the book by Kalen Delaney where she has mentioned the following paragpraph in Chapter 7 (Index Internals):
Many documents describing SQL Server indexes will tell you that the clustered index physically stores the data in sorted order. This can be misleading if you think of physical storage as the disk itself. If a clustered index had to keep the data on the actual disk in a particular order, it could be prohibitively expensive to make changes. If a page got too full and had to be split in two, all the data on all the succeeding pages would have to be moved down. Sorted order in a clustered index simply means that the data page chain is logically in order.
Then I read the book on SQL Server 2000 (on Perf Tuning) by Ken England. He says the clustered index stores data in physical order and any insert means moving the data physically. Also the same statement is echoed on the net by many articles.
What is the truth? How are really clustered index stored? What does physical order in the above statement really mean?

Hello,
I am trying insert the "Order by" clause into DMX but nothing is working.
INSERT INTO MINING STRUCTURE [ARS] (
[OrderID],
[Product_Table](SKIP, [Product])
)
SHAPE {
OPENQUERY ([dwMDA on PSD_TEST_TEST], 'Select Top 30000 "OrderID"
From "dwMDA"."dbo"."vDetail" Order By "OrderID"')
} APPEND
( {
OPENQUERY ([dwMDA on PSD_TEST_TEST], 'Select Top 30000 "OrderID","Product"
From "dwMDA"."dbo"."vDetail" Order By "OrderID"')} RELATE [OrderID] TO [OrderID]
) AS T
This is the DMX for market basket analysis.
I am also unable to use "order by" when i pull data into excel.
here's an example of something that doesn't work:
Select Top 20000 "OrderID","ProductGroupDescription"
From "dwMDA"."dbo"."vDetail"
Order By "OrderID"
Can someone show me the exact working SQL commands they are using for the "Order By" clause when they import data from sql into an excel spreadsheet?
Even better would be if someone
1. Open excel, and go to the data mining tab
2. Click on the Cluster Button
3. Select Analysis Service Data Source
4. Input a command the includes "Order By"
5. Run the model
6. Show me the tracer.
Thanks
Davy

Hi I have a database that has a table. I have a page that you can enter info into text boxes and insert into the database table. They are supposed to be entered in numerical order. 1,2,3, etc. I have a primary key that is an integer for this function but for some reason after entering a certain amount of records the number id be out of order. So for instance if I enter 10 records they will all be there but some may be out of order. 7 will be before 6 or something of that nature. Does anyone have any idea what may be causing this.

I'm asking my previous question in this new thread with more specific data and condition.I have below sample data,
DECLARE @DATA TABLE (U_ID INT, U_NM NVARCHAR(20), U_DT DATE, U_ORD INT, P_U_NM NVARCHAR(20) NULL)
INSERT INTO @DATA VALUES (1, 'Design', '06/15/2015', 2, NULL), (1, 'Plan', '07/01/2015', 1, NULL), (1, 'Cust Plan 1', '06/10/2015', 0, 'Plan'), (1, 'Cust Plan 2', '06/05/2015', 0, 'Plan'),
(2, 'Design', '06/25/2015', 2, NULL), (2, 'Plan', '06/20/2015', 1, NULL)
We have 2 different U_ID (1, 2) and I want a SELECT query to display,
1. For U_ID = 1, we have 2 parent U_NM (Design & Plan) and Plan having 2 child (Cust Plan 1 & Cust Plan 2).
2. I want to display parent U_NM ORDER BY U_ORD
3. If any parent having child element, then need to show immediately under that parent and ORDER BY U_DT
4. For U_ID = 2, we don't have any child, hence display ORDER BY U_ORD

I have a data load process that reads data from flat file into a Stage table in sql server. The order of the records in the stage table is exactly same as the order in the flat file. The identity column on the Stage table (which is also the clustered index) represents the exact line/row number of the data in the filat file. I perform some transformations on the data in the stage table and then insert it into a cumulative table which has a clustered index on an identity column again. When I do this, does the order of the data in the cumulative table be in the same order as the data in the stage table? Anyone, please let me know if I can rely on SQL server to maintain the same order or I will be forcing a sort order on the Identity column (clustered index) of the stage table when I insert the data into a cumulative table.
Thanks in advance!!
