I've here a shell plugin and it's compiling fine and can be viewed in BI Dev Studio when choosing the DM technique using the proper wizard.
I also have here a K-Means implementation that estimates the number of clusters using a statistical semi-empiric index (the PBM index).
This implementation is done in C# and works fine. But it has to receive all the data of the database (all variables for each row) in order to do the proper vectorial calculations in a CSR (Compact Sparse Rows) way.
Besides, as you know, K-Means needs all the data at once because of the clusters mean (centroid) calculation.
So, I have some questions:
1) Where to place the call to the K-Means implementation in the shell passing as argument an object holding all the data ?
2) After this call, with the data clustered, what other objects must be modified in order to use Microsoft Cluster Viewer ?
3) I will need to create a new column or a new table on the database to specify which data belongs to which cluster. Can I open an ADO connection as I normally do in other programs from inside the plugin or is there another (easier/better) way to do so ?
I have a database with table representing city blocks, houses, and people. On my main aspx page, I have a datagrid which displays a list of the blocks, followed by a count of the houses in each block, followed by a count of the people in each block. Right now I have something that works, but it is awful. Every time the page loads it makes a ton of connections to the database, and I have convoluted spaghetti code. Now I need to add more functionality, but I can't rightly do that until I find a more efficient way to do this.Step one. The program connects to the database and gets a list of the blocks using the statement "SELECT blockid FROM blocks"Step two: The program iterates through each blockid in the list and executes the statement "SELECT houseid FROM houses WHERE blockid = (whatever)"Step three: The program counts the rows returned from step two to determine the count of how many houses are in that block. Step four: The program iterates through each houseid from step two and exectues the statement "SELECT COUNT (personid) FROM people WHERE houseid = (whatever)" the result is added to a variable that keeps a running count.Step five: the final value of the variable in step four is the number of people in that block.My question for you is, how can this be done more efficiently? Can I group together some awesome SQL statement that will get these counts? I thought about doing something like "SELECT blockid (SELECT COUNT houseid FROM houses WHERE blockid = something) as HouseCount" but I can't figure out how I could take the value in the first column (blockid) and pass it to the inner select statement.Any thoughts on how to make this better? Below is the full code for my function, in case you want to examine in more detail. Also, I am in the process of changing the select statements into stored procedures, so don't beat me up too badly over that bit of ugliness in my function. Thanks.Private Function GetBlockDataSet() As DataSet Dim myconnection As SqlConnection Dim objDataAdapter As SqlDataAdapter Dim query, connectionstring As String Dim tempDS As New DataSet Dim houseDS As New DataSet Dim peopleDS As New DataSet Dim DC1 As New DataColumn Dim DC2 As New DataColumn Dim i, j, peoplecount As Int32 Dim DR, DR2 As DataRow query = "SELECT blockid FROM blocks" connectionstring = configurationsettsing.appsettings("ConnectionString") myconnection = New SqlConnection(connectionstring) objDataAdapter = New SqlDataAdapter(query, myconnection) objDataAdapter.Fill(tempDS, "BlockList") DC1.DataType = System.Type.GetType("System.Int32") DC2.DataType = System.Type.GetType("System.Int32") DC1.ColumnName = "HouseCount" DC2.ColumnName = "PeopleCount" tempDS.Tables("BlockList").Columns.Add(DC1) tempDS.Tables("blockList").Columns.Add(DC2) i = 0 For Each DR In tempDS.Tables("BlockList").Rows query = "SELECT houseid FROM Houses WHERE blockid = '" query &= tempDS.Tables("BlockList").Rows(i).Item(0) query &= "'" objDataAdapter = New SqlDataAdapter(query, myconnection) objDataAdapter.Fill(houseDS) tempDS.Tables("BlockList").Rows(i).Item(1) = _ houseDS.Tables(0).Rows.Count tempDS.Tables("BlockList").Rows(i).Item(2) = 0 j = 0 peoplecount = 0 For Each DR2 In houseDS.Tables(0).Rows query = "SELECT COUNT (personid) FROM people WHERE HouseID = '" query &= houseDS.Tables(0).Rows(j).Item(0) query &= "'" objDataAdapter = New SqlDataAdapter(query, myconnection) objDataAdapter.Fill(peopleDS) peoplecount += peopleDS.Tables(0).Rows(0).Item(0) j = j + 1 peopleDS.Clear() Next tempDS.Tables("BlockList").Rows(i).Item(2) = peoplecount houseDS.Clear() i = i + 1 Next GetBlockDataSet = tempDS ' Here comes the garbage collection myconnection.Close() myconnection.Dispose() myconnection = Nothing objDataAdapter.Dispose() objDataAdapter = Nothing tempDS.Dispose() tempDS = Nothing houseDS.Dispose() houseDS = Nothing peopleDS.Dispose() peopleDS = Nothing DC1.Dispose() DC1 = Nothing DC2.Dispose() DC2 = Nothing
I just finished a lengthy process (for me) of writing this cursor that gets each row from the Fact table, and creates a running total of the billable hours (hours from rows where BillableType = 1). It starts over when the month changes, the year changes, or the employee changes.
I did this again for a running total of billable hours for the year.
I put these in 2 stored procedures and run them in an Execute SQL control flow task in my SSIS package. It seems like SSIS is designed to make this kind of procedure simpler, and I'm wondering if I'm doing this in the best way, or if there's a more efficient way to do this using tasks inside SSIS. Can anyone advise? Any help is greatly appreciated.
Best, Andy
Don't feel obligated to read this cursor if you understand the problem above. It's not color coded because when I copied it from SQL I lost the tabbing on the case expressions.

These are the 24 load values with the load _id I have lots of rows with load_id starting from 1- 100 Output should be to display the load_Id,load_max, load_min for each row...(after comparing the 24 loads with each other) How can I do it with sql server.
i get just as frustrated each time i try to configure email alerts on failed jobs on ms sql, it is beyond me why microsoft couldn't just let you point out an SMTP server to send through and be done with it.
is there a way to avoid having to setup an email client on our sql 7 and 2000 servers through some 3rd party app or other simple solution?
I have a table that is corrupted and want to remove and add a backup version of it. How can i remove this table and add it again preserving all the foregin key restraints, permissions, dependencies, etc? Simply exporting and importing does not work. I could painfully remove the table and then painfully reconnect it again, recreating all the foreign key restraints, etc, by hand; but there has to be an easier way! What is the How-to?
Dear AllI am very new to MS SQL Server and I am wondering is there some toolwhich would allow me to build pivot tables in SQL more easily. At themoment writing a query can be quite challenging and difficult.Is there any software which allows you to do it more intuitively andgives you some visual feedback about query you are building?I would be very grateful for any help with this.wujtehacjusz
I'm trying to figure out what solution (replication, mirroring, clustering) would work best for me.
I have been reading many articles in BOL and in this forum. Most talk about getting data TO a backup/standby/subscriber, but I can't find a lot of info regarding getting the data BACK after a disaster is over.
We have a main office and a disaster recovery facility. Most of the time there are no data updates at the disaster location. So, I need to get data to the disaster facility via WAN (latency is not a huge issue - end of day syncing is fine) for backup purposes. In the event of a disaster, the main office will be offline and data changes will happen at the disaster site. When the disaster is "over" and we return to the main office, what's the best scheme to reverse the data back to the main office to start business again? We are a financial company, and have gigabytes of relatively static data. Most changes are current day. So, to snapshot a 100GB database when I know only a few hundred MB changes a day doesn't seem feasible to me.
Most replication scenarios (at least from what I see) can't easily "reverse" the replication after a disaster situation. I'm looking at merge replication on a schedule which seems to look good, but was wondering if anyone else has any ideas or suggestions?
I'm trying to select from a table with three columns. I want these columns to be spread out among multiple columns based on the values. I hope someone can shed some light on this. I might be able to use pivot, but don't know how the syntax would roll for this.
Here is the example of dummy values and the output I am trying to obtain.
drop table table1
create table table1
(Category int, Place int, Value int)
insert into table1 values
(1, 1, 20)
insert into table1 values
(1,2, 12)
insert into table1 values
(1,3, 30)
insert into table1 values
(2,1, 34)
insert into table1 values
(2,2, 15)
insert into table1 values
(2,3, 78)
select Category,
(select top 1 value from table1 where place = 1 and Category = t1.Category) as place1,
(select top 1 value from table1 where place = 2 and Category = t1.Category) as place2,
(select top 1 value from table1 where place = 3 and Category = t1.Category) as place3
I have a bit of brainteaser that's going to take some serious thought.
I'm importing information from .xls files into a SQL table. The problem is I need to check for dupes and increment certain fields on success of dupe find and then not insert or delete the dupes.
For example, if I have Adam, Turner, 32, 50 already in the table and someone tries to insert Adam, Turner, 32, 50...I need it to increment to read Adam, Turner, 64, 100 and not insert the record. (Notice 2 fields were incremented.)
With that, I have created an INSERT trigger as follows:
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER Trigger [dbo].[trgInsertCheck] ON [dbo].[MyTable] FOR INSERT AS BEGIN EXEC sp_UpdateDupes EXEC sp_DeleteDupes END
The first stored procedure checks for dupes and updates if any dupes are found as follows: --------------------------------------------------------------------------------------------------------------------------------------
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER Procedure [dbo].[sp_UpdateDupes] AS
DECLARE @FirstName varchar(20), @LastName varchar(20), @Age int, @Widgets int DECLARE c1 CURSOR FOR
SELECT FirstName, LastName, Age, Widgets FROM MyTable GROUP BY FirstName, LastName, Age, Widgets HAVING COUNT(*) > 1
OPEN c1 FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets WHILE @@FETCH_STATUS = 0 BEGIN
UPDATE MyTable set Widgets = Widgets + @Widgets, Age = Age + @Age WHERE FirstName = @FirstName AND LastName = @LastName
FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets END CLOSE c1 DEALLOCATE c1
Lastly, it finds all dupes, deletes them and inserts one row back in as follows: --------------------------------------------------------------------------------------------------------------
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER Procedure [dbo].[sp_DeleteDupes] AS
DECLARE @FirstName varchar(20), @LastName varchar(20), @Age int, @Widgets int --declare all fields in table
DECLARE c1 CURSOR FOR
SELECT FirstName, LastName, Age, Widgets FROM MyTable GROUP BY FirstName, LastName, Age, Widgets HAVING COUNT(*) > 1
OPEN c1 FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets WHILE @@FETCH_STATUS = 0
BEGIN --Delete all dupes...the cursor remembers the current record
DELETE FROM MyTable WHERE FirstName IN (SELECT FirstName FROM MyTable GROUP BY FirstName HAVING COUNT(FirstName) > 1) AND LastName IN (SELECT LastName FROM MyTable GROUP BY LastName HAVING COUNT(LastName) > 1) AND Age IN (SELECT Age FROM MyTable GROUP BY Age HAVING COUNT(Age) > 1) AND Widgets IN (SELECT Widgets FROM MyTable GROUP BY Widgets HAVING COUNT(Widgets) > 1)
--insert the current record back into the table
INSERT INTO MyTable(FirstName, LastName, Age, Widgets) VALUES(@FirstName, @LastName, @Age, @Widgets)
FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets END CLOSE c1 DEALLOCATE c1
Is there an easier way to do this?
(I know Age doesn't make much sense in this example but just replace it with a field would logically be incremented such as wadgets.)
I am writting a T-SQL script to install my database. I have figured out all the sets except 2 areas.
1. Give login db_datareader / db_datawriter permissions to a DB 2. Add a DTS Package, it uses a script, and schedule it.
Here's how I do them in EM....
Issue 1: Security - Logins, Right click on login, select properties In database access tab, check Permit for DB In database role, check public, db_datareader, db_datawriter.
Issue 2: DTS - Local Packages Right click on local package, new package. Create SQL connection & exe SQL task (attach seperate SQL script) Save Right click on newly created package and schedule
Hello everybody , I want you to explain me something that i find a little strange. Yesterday i had a problem with a huge log file and a friend in here helped me fix this by making a log back up and then shrinking it to 200 MB.Everything went fine.When i returned home i tried something else in a test environment..Here what happened: I Got a full database back up. I dropped the database. I created a new one with 1GB mdf and 250MB ldf. I vanished the log back -up I restored the mdf file on the new database The log file again had the same huge size after the restore. How did this happen?
One interviewer has asked me the following question: What are the things that you consider while designing database? I have told about integrity constraints, and normal forms. but he has added 15 more concepts like 1. indexers 2. Table columns 3. Table rows 4. search facilities 6....... Can any one give full Idea on this question? Thanking you Ashok kumar.
SQL 2000I have inherited an application where many of the automated processescall a proc that simply returns the number of records with a NEWstatus.In watching the process in SQL, I see this ends up blocking a lot ofprocesses - many like this are called every 5-30 seconds ...I wish to replace COUNT(*) with EXISTS if that will make things operatefaster with no locks ...Thoughts ...Thanks everyone !!Craig
You can use a Select top @variable in sql server 2005:Thus:--'Throttle' the result set:Select Top (@MaxBatchSize)KeyID, LId, ArrivalDt, CaptureDt, Lat, LongFrom GPSDataOrder By CaptureDt DescMakes messing with Set Rowcount *so* redundant :-)
I have made a report in SRS and am not sure of how to do some of the functions I need.
In SQL I can use UPPER to convert to upper case, SRS doesn't seem to like this. The report runs but the line that is to be upper case is missing. If I remove the UPPER word from my query it works fine just displaying in lower case. Am I doing something wrong?
In Excel 2007 (I am converting my report from Excel to SRS) there is a function called NETWORKDAYS (Returns the number of whole working days between start_date and end_date. Working days exclude weekends and any dates identified in holidays. Use NETWORKDAYS to calculate employee benefits that accrue based on the number of days worked during a specific term.) Is there something similar I can use in SRS?
I'm creating a small application for my local school district that will allow them to do a small management of inventory.
Is there a way to create an executable script that will create the default databases the first time? If so, what all do I need to do for the script and to make it execute? I want to make a section in my OPTIONS area where users can put the path to their db (will not be hosted on the same PC as the software) along with the username and password for the db. I know I can store this information in a predetermined variable in the program so that it can reference it off and on.
Could someone please help me with this..... If it's in the wrong forum please let me know.
I am a newbe in this and I tried to find the information on the msdn but could not find a god answer.
I am using VisualStudio Express 2005 and a SQL Server Express version.
In a Visual Basic application I use "radio buttons", "tick boxes", "Combo Boxes" and "Numeric Up Down".
But I cant figure out what data type to use to save the data in a SQL server.
It would be nice to have a document that maps the different data types to use in SQL Server according to what object you are using in the Visual Studio.
I've got a .dtproj project along with 10 dtsx packages. Up to here everything is fine, every package have its own source files, sql destinations and so on.. Issue comes when I try create a flat file source connection for the eleven one.
I get this message:
The component has detected potential metadata corruption during validation. Error at Data Flow Task [Flat File Source [1]]: Failed to find any non-special error column in output "Flat File Source Error Output" (3).
It may not be possible to recover to a valid state using a component-specific editor. Do you want to use the Advanced Editor dialog box for editing this component?
Otherwise if I'm gonna to open a new .dtproj project separately no problem at all, I mean, appears the suitable window, "Connection Manager", "Column", "Error output" on the left and so on..
It's very strange. The rest of the packages, the same situation. Fortunately, all of them are stored on the server.
I don't get the point at all. Could you please tell me what the hell is happening?
http://blogs.conchango.com/jamiethomson/default.aspx has a lot of great tid-bits for SQL 2005.

Please help! I am really running out of ideas.... and I need to have this setup in a few days....
A while ago I installed SQL CE on my decive. Unfortunately, it crapped out at one point so I'm reinstalling what needs to be put back on. I'm pretty sure I just used the CAB files to do this (but I might be mistaken). In any case, I remember there being an application that allowed me to do queries, browse data, etc. on my device's databases... I'm pretty sure it was just something included with SQL CE.
I already have the CF installed. I have all of the SQL CE CABs installed as well (I think)... but for some reason I simply cannot remember what CAB or other installation that would contain the browser, query creation thing, and so on...
Anyone have any idea what I'm rambling on about? Thanks!
I have a main report and some subreports. What i want to achieve is the subreports would be dynamically sent parameters to and the layout would change depending on some parameters sent from the main report. So there ia going to be a main report that is constant but the subreports data and layout could change.
Another question is can i have an expression that would hide a subreport if there is no data in the subreport?
