I am trying to soak in all this information regarding SQLCE and was hoping someone could set me off in the right direction.
Scenario:
I have an Windows Mobile 5.0 data collection application that I need to sync with a desktop database. I will need the ability to sync 1 or more Pocket PC's with a desktop database.
Questions:
1.) Assuming I need to sync the data, is using a SQLCE database on the device AND the desktop a viable solution?
2.) If not, would my only other option be to use SQL Server Express (SQL Server is not an option, $$$)?
3.) Keeping simplicity in mind, what would be my best choice of syncing technology? RDA? Merge Replication? Microsoft Synchronization Services for ADO.NET?
Generally speaking, I want to know if YOU were starting from scratch, what combination of technologies would you use?
In the readme of v3.5, it mentions that if I use 3.5 to open a database file created by previous version, the version number will be updated to 3.5, so I opened it in c# and run some select statement, then I run the verify() command and here's what's returned:
it seems the database file did not get updated to v3.5. Unless it's returning original info.
Then, I take this same database file and try to access from another project with v3.5 runtime + Enterprise Library, and it generates this error:
An exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in guardian.exe but was not handled in user code
Additional information: You are trying to access an older version of a SQL Server Compact Edition database. If this is a SQL Server CE 1.0 or 2.0 database, run upgrade.exe. If this is a SQL Server Compact Edition 3.0 or later database, run Compact / Repair. [ Db version = 3505053,Requested version = 3004180,File name = D:Dataceguardian.sdf ]
I am confused. Shouldn't 3.5 opens it up regardless of what version it is?
I just attempted to upgrade to SQL Server Compact Edition (2005? 3.1?). The install appeared to go ok but I have no idea really and judging from the version numbers that appear in the references of my projects, I'd say there could be a problem. First, here is what I installed (and the order I installed it):
1) SQL Server 2005 Compact Edition (SQLServerCE31-EN.msi) 2) SQL Server 2005 Compact Edition Developer SDK (SSCE31SDK-ENU.msi) 3) SQL Server 2005 Compact Edition Tools for Visual Studio 2005 SP1 (SSCE31VSTools-ENU.exe)
The first two installs went normal and said they completed successfully. The VS Tools install was strange... it appeared to install but there was no message saying it was complete or successful. The install dialog just disappeared when it was done.
I had some projects that already had references to SQL Server Mobile 2005, so I loaded up a few of those projects, went to the references and removed the SqlServerCe reference and re-added it. I figured the version number would change but it didn't. The version number in the references dialog is 3.0.3600.0. However, the file that it's pointing to is 3.0.5300.0 (browsed to it in Explorer and looked at the properties). Does anyone know what the real version of SSCE is now?
Also, when I removed the reference to SqlServerCe and added it back, I got an application error in VS2005. This has happened every time with every project I've tried. I have to remove the reference, exit VS, reload VS and add the reference back. Which may all just be a waste of time since it doesn't look like it's doing anything.
One other small thing I noticed in the references is that the path for SqlServerCe has an extra between the "SDK" and "SQL Server" directories:
C:Program FilesMicrosoft Visual Studio 8SmartDevicesSDK\SQL ServerMobilev3.0System.Data.SqlServerCe.dll
I'm very confused at this point and hope someone can clear some of this up for me. Thanks!
I am currently upgrading our ppc app (written in .net 2003) to .net 2005 and from sqlce 2.0 to 3.0. The new application runs out memory(storage) when handling lots of data transactions (both in case of using sqlcedatareader, and dataset ). There is no memory leak issue here, sqlce 3.0 simply uses a lot more (3 times more) memory than sqlce 2.0.
Our applicaton runs fine using sqlce 2.0 and .net 2003, but fail due to memory shortage
with the upgrades(which has the same code). Anyone can shed some lights on this issue?
Does anyone have any instructions on how to go about uprading a .sdf file from sqlce 2.0 to sqlce 3.0?
I found this on an msdn website (link: http://www.microsoft.com/sql/editions/sqlmobile/upgrading.mspx) but as you can see its very lacking on detail. (I included the link and content referring to upgrading the database files so you won't have to go to the link to see the part referring to upgrading the database.) I tried to run the upgrade.exe on my device but it doesn't explain how you're supposed to point it to the .sdf that you are trying to update. Here is the content on the above web page.
Upgrading Database Files You can upgrade a database created with an earlier version of SQL Server CE 2.0 to a database created with SQL Server Mobile by using the SQL Server Mobile Database Upgrade tool (upgrade.exe). The Database Upgrade tool runs on a smart device.
When you run the SQL Server Mobile Database Upgrade tool, the new SQL Server Mobile database is created on the smart device. The new database, with the file name extension .sdf, contains all the data that was in the source database. You need to reinitialize the upgraded database to continue using it for replication.
Note: If you are using replication or remote data access (RDA) as a connectivity solution before upgrading to SQL Server Mobile, you must synchronize the source SQL Server CE database (subscription database) with the SQL Server database (Publisher). The reason for synchronizing before upgrading to SQL Server Mobile is to ensure that any changes that exist in the tables on the SQL Server CE database are updated on the SQL Server database, because after the upgrade you must resubscribe or repull using the new database.
1. Is it legal and OK to use a MSDN SQL copy on a production environment or is it strickly for test environments ??
2. If I own a legal copy of SQL 7 with 5 cals, can I legally use SQL MSDE and have more than 5 people access my SQL server or am I also limited to 5 users as my original ??
My app is working on my local system with the vs2008 development server. It's an asp.net app and I added the line: AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);
So it works fine on my system. But I can't get it to work on shared hosting. I have uploaded all the sqlce 3.5 dlls to the bin directory. I am stuck at the error:
Access to the database file is not allowed. [ File name = ]
There actually is a file name in the connection string, and I set the permissions wide open on App_Data to test this.
What are the .net framework requirements for sqlce 3.5? I can't find this info anywhere.
I know sqlce 3.5 is not recommended for asp.net, but it is not the main site database but is used for a setup database utility to be installed for a windows app.
This is my first time posting in this forum, so forgive me if my post is out of place. If so, let me know.
I am trying to get started setting up a development server on Windows 2000. These are the componants I have installed so far:
- IIS 5 - MSDE Database Server - .NET Framework 1.1 - MDAC (Microsoft Data Access Componants) - ASP.NET Web Matrix
I have also downloaded a quickstart example, TimeTracker, to learn from.
Here is my problem: When I try to install TimeTracker, it does not detect a database connection. Also, when I try to connect to a database in Web Matrix, it says I need to have client tools installed. What are these and how to I get them?
Is there anyone that can give me a hand with this? Is it a matter of running the MSDE service? If so, how do you do this?
My apologies for not being more knowledgable, but thanks for helping me get started.
I just installed SQL server 2005 with SP2 on Vista business.
When I open Management Studio, and try to Register a new server, I get this message:
Cannot connect to MyServer. Additional information: An error has occured while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could nor open a connection to SQL Server) (Microsoft SQL Server, Error: 1231)
When I open SQL Server 2005 Surface Area configuration and click on Add New Administrator, there are no Available privileges. Not sure if this is relevant.
Don't know what to do, any help will be appreciated.
I have just installed SQL Server at home. Had a bit of experience at work, but at home I have to get started from scratch.
Enterprise manager says 'Connection could not be established'. In this error it talkes about 'registration properties'. I am (by default ?) a member of SQL Server group, but I have no sub items, like databases. And how do I get to where I can edit stored procedures ?
As you can see I'm quite a novice, but with a little nudge I can would a lot out myself. But not all. If you can help me now, I'll be back soon.
i have roughly 10-15 access databases that i am trying to run through sql server express, i installed this thing thinking it would would "just work minus a little configuration", what a misconception.
so do tell, what do i need to do. i have sql server express running, it is configured to allow remote connections. i know the path's of these access databases. how do i attach them. i saw something about the command line interface but im not interested in that because of the number of databases i will need to manage, not to mention trying to add an additional one 6 months down the road and i will be lost all over again. i thought about downloading SQL Server Management Studio thinking it would be a "gui side" to the CLI version. while it was downloading, it said i need XX program, i go to that page, it says i need XX and XX first, it is turning into a pyramid scheme to install a billion programs.
so point blank, i want to share some access databases to my local lan, i have sql server express installed and running. what do i need to finish this out. the simplest and smallest footprint solution is needed.
all this because the program im using cant do remote databases. ugh.
I am trying to make a small vb.net program in visual studio 2005 edition. I would like to have a SQL database with it.
I have the Microsoft Visual Studio and SQL Server 2005 installed on my PC. I am running XP but will be moving it all to a new pc running Vista next week.
How to I get the SQL database started ? I am not using the express edition.
This is a repost of my post on the VB Express board.
I would like your opinions.
I am a network guy. I learned basic years ago. I can do some html edits as needed to change sites.
Today I would like to start the long process of learning VB with .net applications. I thought I could start with Office developer xp to learn VB. I have that package.
I also would like to be able to build SQL quaries and integrations or automate and manipulate data exports and imports later down the road.
Example: Export various order and customer information from a shopping cart and import it in to Quickbooks or MS Accounting.
First off I need to be able to build web sites and I know I want to grow into VB and SQL.
What should I do?
Learn HTML from web monkey?
Start with Office xp developer Tutorials?
Start with VB Express?
Buy a book?
Can someone tell me where to start and when to move to the next language?
What is the best resource to get to it, without the bla bla bla and a commnd/syntax refference?
How do I mix Html, CSS and .Net (VB)...in the learning process?
I would like to get the fast track for the long haul.
I am looking to learn about reporting with SQL Server for my company
Currently we have an applicaiton running on SQL Server 2000 and have SQL Server 2000 Reporting Services installed. However, I have VB Express and Web Development Express 2005.
How do I get started here? What versions "work" with what? Do I need to either upgrade the DB to SQL 2005 or find VB.net 2003, or can I use what I have to get started?
hello, i own about a dozen interactive forums (see example at http://ConcealedCarryForum.com for one of them) that i host on a windows 2000 server dedicated server out of my home on a commercial cable backbone. the forums are ASP using Access DBs. we have outgrown the capabilities of Access and are getting complaints from DB lag during peak usage, and i must upgrade my DB to ensure the QOS end users get from my forums. i have no intention of switching over to php/MySQL/linux formats.
i tried unsuccessfully to get MySQL to play nicely in a windows environment, and recently learned that MSSQL offers free versions, the compact and the express. trouble is, i know absolutely nothing about DB management. Access is idiot proof so i have used it as long as i could. now i find myself in a scramble to learn how to create, employ, and use a more powerful DB.
for my intended usage (running about a dozen DBs on a dedicated server), will compact or express be the appropriate version to start learning? for my intended usage, is there any benefit to downloading/installing/learning the additional tools that are also available? if so, which tools? where do i learn how to create new DBs, and what tools do i need to do this? most tech papers ive seen on MSSQL assume a prior working knowledge of MSSQL DB management and im coming into this completely ignorant but willing to dedicate myself to learning.
I'm studying some articles about DMX and i have a question. DMX statements is only for prediction?
Can i create a model and run a classification/clustering/decision tree algorithm through DMX instead of prediction?Because all the examples i found are talking about prediction.
Are there any other sources i can study, so i can have a better understanding of what DMX does?
I am using this program for the first time but as it has no direct interface on its own, I would like to ask if anyone could help me get a database up and running.Nothing fancy but simple and functional for my staff to use for basic csv searches and so forth. skywalkerza@highveldmail.co.za
Hi folks... this is part complaint, part request for help. I have an Access db that I'd rather were an sql db. Partly to learn sql and partly because all of the asp.net examples use sql and don't seem to work with access.
I installed VS2005 which includes sqlexpress, but there's no front end to it.. there's no way to "talk to" this sql2005. Can't seem to create tables, etc.
So, I installed SQL 2005 Development server... still no front end. Just some config tools that I presume I may care about some day but don't mean anything to me just yet.
I'm on XP Pro so can't install SQL 2005 Enterprise, but I discover a CTP called Management Studio Express. Well, we all know how robust CTPs are, nevertheless I install it and boy is it friendly.
At this point I feel as though I've missed The Big Thing that had I not missed I would be a lot further along.
Maybe the best way to express my question is to ask for what the heck I should have done in order to be learning sql at this point instead of having run out of time again.
Thanks for any insight.
Best,
Eric
PS... hmm, seems like this is mostly complaint... sorry.
I have a job for run DTS packages, My Job got failed due some reason,I corrected the problem a started Job again.Here problem is I for got to note the start time.Now I want find out from how long it is running or it what time it started.
Hi - I need to start from the beginning with SQL Server 7 2005 Express. I want to get financial data and perform analysis in conjunction with Excel. I have downloaded the file from Microsoft and would like a resource for getting going. What is the best way to go?
While I have been programming .Net for four years and T-SQL for about 12, I am a newbie to the whole SQL CLR thing. I have VS.NET 2003 on my machine, and I installed the client tools for SQL 2005 which also installs VS 2005 for SQL. Yet when I open VS 2005, it only has Data Analysis projects, but no Database projects. If I go into VS 2003 and try to import some of the assemblies I have found by googling 'SQL CLR' - VS 2003 won't let me add them.
Exactly what do I need to install so that I can get started? Do I need an instance of SQL server running on my machine? (I currently do not have a server running, only the client tools are installed)
We have over 1000 terminals running CE 4.2 on an x86 cpu currently using SQLCE 3.1.
We have just upgraded to VS 2008 and found the projects have been upgraded to reference SQL CE 3.5 - this is great, as we wish to use things like TOP etc.
However, all the distributable packages only include CAB files for CE 4.2 for the ARM Processor, or CE 5.0 for the x86. Is there a CAB package available for CE 4.2 for the x86 CPU? (please...)
Even just the relevant .DLL files would be fine as we repackage them ourselves anyway.
Hi i developed Wm5 PPC application with sqlce database. i Create Cab file when i install in my HP WM5 PPC that will showe the Message sqlcewm.dll missed. Please tell me 1)sqlce30.ppc.wce5.armv4i 2)sqlce30.wce5.armv4i 3)sqlce20.ppc.wce5.armv4i..Please Help me
In my homegrown data layer, I added the ability to do Order By Clauses.
I do one query with an Order By clause (all 6 records in the table retrieved). Then I do a 2nd query without an Order By (36 of around 200 records in the table retrieved)
And I'm getting Native Exceptions.
ExceptionCode: 0xc00000000c (Null Pointer I believe) ExceptionAddresss: 0x00c3703c (looks to be in sqlcese30.dll) Reading: 0x00000005
I ran thru with the debugger, and am finding the error happening inside of a SQLDataReader.Read() call. It's trying to read the 14th of the 36 records that the query has found.
I am all but positive I'm not closing this database connection. The problem is happening while I'm looping off the reader data I just retrieved and in this query there was no ORDER BY clause.
I'm at a loss as to what to do about this. I'm not explicitly closing any database connections, and I'm getting the data right after performing the query.
I wrote a very simple C# console application which was designed to give us a rough idea on the performance and reliability of SQLCE (the source code without metrics has been posted to this group recently). What I've found is that there are major performance and reliability issues with SQLCE 3.0 as opposed to SQLCE 2.0. Whereas SQLCE 2.0 seems to be fairly consistent in terms of it's memory usage and the amount of time taken to insert rows into the table regardless of the size of the table (to a limit, after about 300,000 records it too has major performance issues), SQLCE 3.0 seems to slow down noticably and continually use more memory even after a few thousand records are inserted and actually crashes (consistently) after 25592 records are inserted!
What gives? Based on this it would seem that SQLCE 2.0 is far preferable for an unattended device that needs an uptime of over 30 days whilst constantly (several times per minute) inserting into the database.
