Why does VS SP1 not include SQL Server Compact SP1 64bit? – Steve Lasker – Surface devices


Of course Compact code bugs can result in corruption. A lot of them have been found internally before v3. They are more logical in nature like index constraint is compromised or a table page says there are rows when there are only We did a very good job in fixing these and they are hard to find now.

For ex: Compact is trying to write to a file and the user simply boots his device. Now file is in half-baked state. How do we avoid this? Well, we use shadow paging to overcome this situation.

We can loosely categorize the db pages into user data pages, system pages and header page. As the name suggests user data pages contain all the user data. Header pages and system pages help us locate a specific user page on the disk.

Then the shadows of the updated system pages are written. Finally the header page is written. The old pages are retained till the header page is updated. This ensures that we have a transactional write to the disk. Either the change is completely present or not. Clearly the above is not enough. Some of the interesting cases are. So the changes supposed to be written to disk could be lost.

The intent is not to blame other components. It means disk write is bad for some reason which is not owned by Compact. The fault is somewhere in the bottom stack and it has to be fixed. Our options are very limited without a repro but we are trying hard to improve our debugging infrastructure.

We are hoping that with this knowledge customers will be able to understand the corruptions better and come up with good practices that would vastly reduce these corruptions. What is new in this Service Pack? SQL Server Compact v3. Server Tools bit and bit See Also: this.

Documentation, Books Online. Where to download? NET Framework v3. Platform Builder 5. I will update this blog post with the download URL soon after they are available. Windows CE 5. Windows Embedded CE 6. There are some optimizations that can be done for an “Sync Services” sync scenario. These are, might not be an exhaustive list. Sync synonym for “Sync Services sync”, in this post interfaces with the providers using DataSet objects. That is, sync uses DataSet to store and retrieve changes happening at client and server.

DataSets are known to be not very memory efficient, and the amount of memory consumed by these, is a bit of a concern when one is using these in device clients in Sync Services. Sync happens in chunks, using the SyncGroups that one supplies. That is, all data in a SyncGroup is logically one sync, and corresponds to one DataSet. However, to ensure logical consistency, you should always keep the tables which are related by a foreign key constraint, for example , in the same SyncGroup.

Example: Tables Order and OrderDetails are related. Tables Customers and ShippingDetails are related. But, these are unrelated to the first set. DownloadOnly; customerSyncTable. DownloadOnly; orderShipSyncTable. DownloadOnly; orderSyncTable. DownloadOnly; orderDetailSyncTable. One for the first set, and the second for the other set.

Also, to increase the performance of enumerating process at server, one can create indexes on the tracking and filtering columns. Since, our server side changes enumerating queries always have filtering based on these columns, one should create indexes on these, so that, enumerating server changes becomes faster, and, sync performance increases.

One can use System. Sometimes, we may have server tables holding and synching data, that is alien to clients. For example, server table has a large GPS map of some place in custom format per row, that is associated with the data in other columns in the row. The map is stored as an image at client side.

And also, since, it is large data, lot of network bandwidth is consumed and response time is compromised for transferring this across. It is better, if one can filter these columns out at server side, rather than sending to client. Another scenario is as follows: The client devices of a Sync application are used by Salesmen of a company, and the server side is the company office, where data pertaining to each salesman is stored in a SQL Server database.

When the client devices sync, they are mostly concerned about the data relevant to them alone, and not to other sales persons. Here also, one needs to filter rows from the table. For filtering data sent from client or at the client side , one can use the callback architecture of “Sync Services”.

Callback architecture of sync: Sync provides various callbacks during the process of Synching. After changing the dataset, effectively, the changes being applied to client database are changed. The same provision is present at server side also. This is one type of filtering, possible at both client and server. Server side gives more options when sending data over the wire. First of all, server chnages are enumerated within the “Sync Services” application itself.

That is because, server change enumeration is done by queries supplied by the Sync Services client. So, which columns to select from server, can be controlled from the client side, when specifying queries like, SelectIncrementalInserts etc This is another way of programmatically filtering server data.

One more option to filter data in a N-tier architecture is that, filtering the wire transferred content. In an N-tier architecture, client and server are in two different, but connected machines.

Web service talks to a backend data store, and services the data and operation requests. In this setting, interesting possibilities like, use of compression over the wire, and filtering over the wire etc When server side data store gives data, it can do some filtering.

Also, the client side proxy can be used to filter irrelevant data. This is another type of filtering. GroupMetadata and eventArgs. DataSet are the ones need to be changed. Steps :. Depending on locale, g et it from below table for 3. You can use Orca. Three letter locale Id. Product Code. Chinese Taiwan. Portuguese Brazil.

Below is the list of locale specific download URLs for x64 3. Manikyam Bavandla. Whenever sync is started, developers provide all the necessary properties to an object of SqlCeReplication class. These properties are provided through the constructors or by directly setting the public properties of the object. In this approach developers need to provide this data for every sync, which forces them to store this data somewhere in their code.

Even if the properties seldom change, developers provide this data all the time. This data includes passwords such as DistributorPassword, InternetPassword, InternetProxyPassword and PublisherPassword which developers are better off, not saving or handling in their code. The benefits of this approach are:.

Code example for calling SaveProperties :. SaveProperties ;. Note: SaveProperties will succeed only if the Subscription is already created on the machine. This simplifies subsequent syncs in that developers need to provide only SubscriberConnectionString to identify the local database to SqlCeReplication object and call LoadProperties. If there are more records, then in additional to SubscriberConnectionString, developers need to provide Publication, Publisher and PublisherDatabase to uniquely identify a saved profile for a subscription.

Code example for calling LoadProperties :. Properties not saved by SaveProperties :. These values must be explicitly provided to SqlCeReplication object for every sync.

Note :. There are two things to note while using this functionality. If we call SaveProperties with required properties missing, this data will be set to default even if there is a saved profile already present for this subscription in the Properties table.

Therefore if the database file is moved to a different machine LoadProperties will fail to retrieve the correct password. Developers need to provide the password and other required properties, and call SaveProperties again to refresh the saved profile on the new machine.

For more information please refer MSDN documentation:. Thanks, Balasubramaniam Bodedhala. Open takes more time and also increases the database file size. Index recreation requires space on database file and hence the database file size will be increased. Because of this index recreation, first database connection open takes more time as it has to rebuild all indexes.

SQLCE 3. NET provider model. In general, the managed classes under ADO. SQL Server Compact native objects are dependent.

For instance, Cursors and Transactions are dependent on Connection object and are expected to be released in the right order. In native application, the developer can dispose the cursors, commands, etc.

Net Garbage Collector there is no particular order in which these objects will be disposed. So what do we do? Our SqlCeConnection object maintains weak references to all objects tied with it. NET application, and then your web application can use it as a database engine. No setup or extra security permissions are required for it to run. You do not need to have an administrator account on the machine.

Just copy your web application onto any server and it will work. This is true even of medium-trust applications running in a web hosting environment. NET application and will start-up when you first access a SQL CE database, and will automatically shutdown when your application is unloaded.

NET Applications. SQL CE 4 works with existing. This enables you to use the same data programming skills and data APIs you know today. Supports Development, Testing and Production Scenarios. SQL CE can be used for development scenarios, testing scenarios, and light production usage scenarios. This is a big change from previous releases of SQL CE — which were designed for client-only scenarios and which explicitly blocked running in web-server environments.

SQL CE is an embedded database — which makes it ideal for development, testing, and light-usage scenarios. Our goal is to enable you to be able to simply change the database connection string in your web. NET projects for the first time. With VS SP1 you can now:. You can take advantage of all of the above features from within both ASP. NET Web Form application. NET Web Forms project. NET application to enable easy deployment. Since it is a new database there are no tables within it:. Once our Products table is created it will show up within the Server Explorer.

This will add a new Store. Choose to use the Store. The wizard will then ask you what database objects you want to import into your model. NET application. This will bring up the below dialog which allows you to pick your Data Source type:. This will bring up another dialog that allows us to pick our model layer:.

Then click next — which will allow us to pick which entity within it we want to bind to:. NET Web Forms. We used a database-first approach with the sample above — where we first created the database, and then used the EF designer to create model classes from the database. Code-First Development enables a pretty sweet development workflow.

It enables you to:. Below is a simple example of how you can use them to build a simple ASP. Then type:. When we enter the above command, the EFCodeFirst library will be downloaded and added to our application:. We create these model classes by writing code. They do not need to derive from any base classes or implement any interfaces, and the properties they expose are standard.

NET data-types. No data persistence attributes or data code has been added to them. We have finished writing all of our code — our last step will be to configure a database connection-string to use.

EF Code First uses a default convention where context classes will look for a connection-string that matches the DbContext class name. NET project. You might ask — but where did it query to get the dinners from? Below is the view we get when we double-click our NerdDinners. With EF Code-First you typically start making database changes by modifying the model classes.

We are seeing this error because EF Code-First automatically created our database, and by default when it does this it adds a table that helps tracks whether the schema of our database is in sync with our model classes. EF Code-First helpfully throws an error when they become out of sync — making it easier to track down issues at development time that you might otherwise only find via obscure errors at runtime.

Note that if you do not want this feature you can turn it off by changing the default conventions of your DbContext class in this case our NerdDinners class to not track the schema version. Our model classes and database schema are out of sync in the above example — so how do we fix this? Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.
