Calculations In SQL Queries Using SQL Server Compact
Feb 1, 2008
Hi Folks,
I am looking for some help on how to do a calculation for each row returned in a query.
For example, I have the following query:
Select Name, Supplier, Colour, Cost, [Cost Inc Vat] from products;
The idea is that Cost and a variable, @vat included in part of the SQL statement (I assume), will be be used to calculate the value of the column [Cost Inc Vat] for each row, but I dont know how to do this.
Is is possible in SQL Server Compact and how can it be done?
End Sub this code worked well. we know sql7 is not compatiable with vista. please tell us how to connect it wiith sql2005 . we downloaded orcas express edition beta. we created a database also. please let u know how to connect with Microsoft SQL Server Compact 3.5 (.NET Framework Data Provider for Microsoft SQL Server Compact 3.5).
we've got a SQL Server 2005 which replicates with an SQL Server Compact 3.5. Every 10 to 20 synchronisations we're getting the error mentioned above. A Soft reset of the device helps to make the synchronization working again.
Why is this error happening and how can we resolve this?
BTW, we've also running system that replicates with an SQL Server Compact 3.0 without having this problems.
everything is ok for first run. but i leave the program relogin than that error occured ppc2003 second edition devices. Windows mobile 5.0 device works fine. can anybody help me?

Declare Function LoadLibrary Lib "coredll" Alias "LoadLibrary" (ByVal lpLibFileName As String) As IntPtr
promo_ID: the id of the web form that site visitors filled out to send us their information PPC_source: If this lead is a result of a Pay-per-click campaingwe capture the name of the search engine Status_ID: Shows if the lead has been contacted, quoted, sold, bad lead, etc. I was asked to come up with a summary report calculating the number of leads under each status ID - for each PPC_source Example:
Total leads |
Google |
Yahoo
Status = pending
Status = contacted
Status = quoted
Status = Sold
Looping over each record (12,000 and counting) to get the sums of each status for each pay-per-click campaign takes a while (not all campaigns / status are listed above). The question: Is it better to retrieve all records in a dataset and do the math in the business layer or is there a way to do the math in a SQL Procedure, or function. Thanks.
Is there a formula for calculating how expensive a transaction will be in terms of disk space used before its run. I dont want it accurate to the MB, but rough enough so I can determine how much additional space to assign to a transaction log or SAN volume.
Currently we're reindexing ~25billion rows, nothing too wide, say 12 columns consisting of 1 varchar(50) and the rest ints, bits and money.Roughly speaking if I reindex the clustered index on an int indetity, (with sort_in_tempdb) how would I calculate the the disk space used?
I am trying to understand why SQL Server gives me significantly lower precision than many of the other sources that have tried when using the POWER function. My environment is 2008 R2 SP2 (10.50.4000.0 X64, Standard edition) on Windows 2008 X64 SP1
-- using results from other sources (c#, windows calc, casio.com) SELECT POWER((1+3.33272237835747E-05),12) -- 1.0004 SELECT POWER((1+3.3327223783495255846580902358195e-5),12)-- 1.0004 SELECT POWER((1+3.332722378349525584658E-5),12) -- 1.0004
It is not important what I am trying to do, but in case it will work, I am trying to calculate the monthly return for a 90-day T-bill given the compounded annual return. x is the annualized return.
I am new to SQL Programming. I am learning the basics. I am trying to create a simple query like this -
SELECT Column_1, Column_2, Column_3, 10*Column_1 AS Column_4, 10*Column_2 AS Column_5,
-- I am not being able to understand how to do this particular step Column_1*Column_5 As Column_6
FROM Table_1 First 3 Columns are available within the Original Table_1 The Column_4 and Column_5 have been created by me, by doing some Calculations related to the original columns.
Now, when I try to do FURTHER CALCULATION on these newly created columns, then SQL Server does not allows that.
I was hoping that I will be able to use the Newly Created Columns 4 and 5 within this same query to do further more calculations, but that does not seems to be the case, or am I doing something wrong here ?
If I have to create a new column by the name of Column_6, which is actually a multiplication of Original Column_1 and Newly Created Column_5 "I tried this - Column_1*Column_5 As Column_6", then what is the possible solution for me ?
I have tried to present my problem in the simplest possible manner. The actual query has many original columns from Table_1 and many Calculated columns that are created by me. And now I have to do various calculations that involve making use of both these type of columns.
Now for the complicated part, a person can take absence(sick,holiday,other) for any part of a day or whole day(s). For these absence periods only the worked time on that day needs to be negated off, not the whole period of time.
So for example
If this person
had a days holiday on the 22nd, shown in the HOLIDAY table as
The 'Leave of Absence' on the 20th had no effect on the total for the day as it was between planned work times. how to do this within T-SQL, as simple as possible as I've got to had this code over to other staff members to maintain, who have not had much SQL experience yet?
I've tried doing it as a temp table, with dual insert/select commands, splitting the times over midnight, which partially worked but missed some of the combinations.
I have a question about a problem that I cannot seem to tackle. I have installed the following programs on Windows Vista:
- SQL Server 2005 - Visual Studio 2008 - SQL Server Compact Edition 3.5 - SQL Server Compact Edition 3.5 Server Tools
I want to do the following:
1. I want to create a SQL Server Compact Edition 3.5 database in the SQL Server Management Studio 2. I want my SQL Express server in SQL Server 2005 to be a distributor and publisher
About 1. In SQL Server Management Studio I cannot choose SQL Server Compact Edition 3.5 . ABout 2. I tried to setup my server to be a distrubutor by running a stored procedure with the following name: sp_adddistributor. I get the following error: This edition of SQL Server cannot act as a Publisher or Distributor for replication.
Trying to learn how to use Sql Server CE, Tutorial says to open server explorer, add connection, new connection, select data source as .net sql ce (words to that effect). On my visual studio, it ain't there and I can't figure out how to get it there. I have uninstall all of the Sql Ce stuff and reinstalled it. So I'm missing some key link. What are the magic incantations to get to first base?
I am having problems installing the SQL Server Compact Server Tools on my Vista laptop to allow me to connect my Mobile Device running SQL Server Compact directly to my SQL Server 2005 database through IIS.
I have done this successfully with an XP machine so I'm not sure if it is Vista problem or not.
I have installed SQL Server 2005 SP2. When I try to install the replication server tools (Sqlce30setupen.msi), in "System Configuration Check" window I get a failure on "SQL Server requirement" that says: "You must first install the Replication Components for SQL Server 2000 SP 3a or higher or the SQL Server 2005 Replication Components" and the client components are full instaled in my computer.
I just installed SQL Server Compact Edition, since I am considering using it instead of SQL Server Express for a local database in my application. The documentation mentioned that I could use SQL Server Management Studio Express to connect to the Compact Edition and create and manipulate databases.
To try to connect, I run Management Studio and bring up the "Connect to Server" dialog. Unfortunately, the pull-down list of "Server name"s does not include the SQL Server Compact Edition server. I do not know how to type in the server name manually, so I cannot connect.
To install Compact Edition, I downloaded it and ran "SQLServerCE31-EN.msi". This installed, and I assume registered, a number of DLLs in "C:Program FilesMicrosoft SQL Server Compact Editionv3.1".
Is there perhaps an additional step that I left out to complete the installation?
Might I need an upgrade to some other components? My Management Studio Version is:
- Microsoft SQL Server Management Studio Express 9.00.2047.00
Which tool can I use for structure editing of SQL Server Compact 3.5 databases? I'm installed SQL Server Compact 3.5. I have SQL Server Management Studio Express which was installed with SQL Server 2005 Express. Unfortunately this SSMS can create and open only 3.1 databases.
I am using SQL Express 2005 server and sql compact edition for my PDA. For synchronization, which SQL Server 2005 Compact Edition Server Tools installation package do I use?
Is it Sqlce30setupen.msi or sql2kensp4.msi or sql2kensp3a.msi? I know for sql server 2005 its Sqlce30setupen.msi. Is it the same for the SQL Express 2005?
I am very new to SQL Compact. I am trying to create one database which can work on the desktop application and also on a pda application. I want to create the database but I am unable to start without Management Studio. Can you guide me to the right tools so that I can create database, view it and manage it use something like Management Studio Express.
Also one more question is if my database needs to be at both places on the desktop and on pda how can i synchronise them. PDA will take using c# application data from RFID scans and then i need to sync that database on the desktop so that reports and other info can be generated from the desktop c# application. How to do this?
Please can you guide me to any webcasts or labs so i can clarify my doubts about the design.
i tried to connect to a SQL Server Compact Database (version 3.5) with SQL Server Management Studio Express (Version 9.00.3042.00).
But i get the follwing error message (sorry, it's a german message):

Is there a solution to manage Compact Databases in Version 3.5?
We are currently having a problem with a client running Vista business for a mobile application that uses SQLCE RDA with the Web Synchronization on IIS7.
I have run through the Configure Web Synchronization Wizard and it doesn't create a virtual directory. I manually create the virtual dir and point it to the new folder the Configure Web Synchronization Wizard created.
Browsing to the url "http://localhost/sqlce/sqlcesa30.dll" gives a valid test string.

Which roughly translates to from the header file ...
#define SSCE_M_INCORRECTPROVIDERVERSION 29022 // The version of the Microsoft OLE DB Provider for SQL Server is not correct. Install MDAC 2.8 or later. [,,,Version,,]
When a Windows Mobile or Pocket PC device tries to do a ServerExecute or Push or Pull it gets this error message with SQLNCLI ...

Message = " [ 9 ]"
NativeError = 29022
numericErrorParameters = {9,0,0}
Source = "Microsoft SQL Server 2005 Mobile Edition"
A very similar error.
From this it seems that both SQLCE 2 and 3 seem to want MDAC 2.8+ drivers. The drivers installed with Vista for SQL Native client seem to be versioned 6.0.* and the required versioning would seem to need to be in line with MDAC 2.8.
Are there installable drivers to bump the versioning of SQLNCLI or SQLOLEDB upto MDAC 2.8+ levels?
Or is there an alternative that will make it possible to run SQLCE RDA apps with Vista as the SQLCE server (i.e. sqlcesa30.dll)?
I am writing an application that is designed for the desktop, or small group (3 or less) desktops. The application is being deployed using the Cassini web server as a complete "embedded" solution. I wanted to use SQL Server Compact because of its small footprint and because of the synchronization capabilities with SQLServer. Also, it is very easy to deploy vs. SQL Server Express. The idea behind this APP is that someone might use it locally and then decide to subscribe to the service and then connect the same application to a web services application. That being said, and with knowledge of Microsoft's stance on SQL Compact under ASP.NET, I have most everything working and it works great except for one thing. When I add a SQLDataSource to the page and set the connection string to my file and the DataProvider to System.Data.SqlServerCe and then bind a data grid to the SQLDataSource, it runs fine on my development machine, but when I deploy to my clean test machine, I get an error when the page loads saying: Unable to find the requested .Net Framework Data Provider. It may not be installed. I can create a dataset in code (in fact,in several other places I do) and it works fine. It is just the SQLDataSource(s) that are throwing this error. I have a copy of System.Data.SqlServerCe.dll in the bin folder and I have all of the compact DLL's in the bin folder as well. I can't figure out what I need to do. I also have a reference to the System.Data.SqlServerCe in the web.config file. Can anyone help?
Hi, We have just installed visual studio 2008 for a windows mobile application development. This application requires a database also. VS 2008 installs sql server 2005 express edition and the sql server compact edition 3.5. We installed sql server management studio but this is for the express edition only. Please let us know how to use a similar tool for compact edition, we could not find any suitable for the same. Regards
I want to develop an application for my company's user to use...I will use VS2005 C# for windows as development tools, and then I will develop the pocket PC or smart Phone for same application.In the first,the database I want to use is SQL Server 2005 Express Edition,but it's difficulity to deploy , because it's fat files ,so if I use SQL Server compact 3.5 ,means I just develop once and I can re-compile the code for user to use Pocket PC and mobile...etc...right?
Does the new SQL server Compact edition RC1 (release in Dec 2006) replace the Microsoft SQL Server 2005 Mobile Edition Device SDK?
OR is this an additional database for specific requirements.
Currently developing against MS SQL Server 2005 Mobile Edition Device SDK;; if I switch to the Compact edition; is there a migration wiarzrd or Upgrade wizard available?
I am new to SQL Mobile developement and trying to developing a small device appliction. My C# code is shown below. My code is executing correctly, but i am not able to see the inserted records in to my SQL Compact database. What i am doing here? Please help.
FYI, I have added the database in to my solution. My solution and database resides in E:\some directory, where as the my assembly code base represents the datasource as \ProgramFilesMobExpTrackerMobExpTracker.sdf.

I am working with Visual Studio Team System 2008. I click File, New Project, Smart Device Project. I select Windows Mobile 6 Standard SDK for the platform, and .Net Compact Framework Version 3.5 for the framework version. When I click OK, I get the following message:
--------------------------------------- The operation cannot complete. To fix this problem, first copy these instructions into a separate file and then perform these steps in the order shown:
1. Click OK on this dialog box and the "Package Load Failure" dialog box which will appear after it, and then exit Visual Studio. 2. Reinstall Microsoft SQL Server Compact 3.5. 3. From the command line, run devenv /resetskippkgs. ------------------------------------
I did all of that, but the message still keeps coming up. Can someone explain how I can create a new project without this message coming up? Thanks.
Hi all, I am just starting to look into this interesting piece of technology, but am a little confused on how this works. I apologize if this has been asked earlier. My question is with this specific SQL server distribution, what is being used as the front end (to create and view your database & tables)? I read that SQL Server Compact Edition RC1 will have runtime only - How will you then get an application to point to a database via SQL compact?
I have an application that uses a SQL Server Compact 3.5 database backend. Everytime the application starts I want to zero out my database, meaning remove all records and reseed all identities. This datatbase is then filled based on a directory structure. Once this DB is filled I then send the entire database to a Windows Mobile PPC device via 802.11g WIFI. Before sending the database I first create an MD5 checksum on both the server and client sides to see if the database actually needs to be transfered. If the checksums match I will not send it as the client already has the lastest copy.
My problem is that I can never count on the database identity values starting at the same number on any particular instance of the application so the checksums are usually different. To solve this problem I need to ensure that everytime I start my server application the database (and all identifiers) will always be the same, will always be as if I just creaed it. How do I do this?!?!?!? This seems like it would be a trivial operation as I can imagine its use in multiple situations. Anyone know how to zero out the database?
Been following a video from Jim Wilson on merge replication between sql server 2005 and compact 3.5. The problem I have is that in the video, the subscriber types say SQL Server Compact, but on my 2005 server it says SQL Server Mobile. I have installed all the parts of Compact 3.5, so how do I get 2005 to use Compact and not Mobile?
I work with a Development board with an armv4 processor for a Windows CE 6.0 application and tried to install there an SQL Server Compact. But it doesn't work. My information from Google and other sites is that the Compact edition of SQL server does not work on a Win CE 6.0 platform.
Does someone can give me to this subject further information€™s? Is there an alternative?
Im trying to install the SQL Server Compact Tools in Windows Server 2008, but the installation program won´t let me continue since it says that I must install the IIS Backward Compatibility Tools. The problem is that I can´t find where I do that.
I know that Windows Server 2008 is not listed as a supported os for the server tools, but surely I must at least be able to install them?
Is there a way to use SSIS to copy data from a SQLServer CE database to a SQL Server 2005 database?
I have a database that has only been used on a mobile device, but now I want to use it among several devices, so I want to copy the structure and data to a SQL Server 2005 database and expand it's scope.
