  • SQL join: where clause vs. on clause

    - by BCS
    After reading it, this is not a duplicate of Explicit vs Implicit SQL Joins. The answer may be related (or even the same) but the question is different. What is the difference and what should go in each? If I understand the theory correctly, the query optimizer should be able to use both interchangeably.

  • Does Microsoft still sell FAST ESP?

    - by Kunal Sen
    I wanted some information about FAST ESP search engine. After failing to get any response from the email query system on Microsoft site I called their ore-sales phone number. The person there told me the only way they sell FAST ESP is as a bundled product with SharePoint. That really does not make any sense and contradicts all the PDF documents they have about FAST ESP on their site. Does anyone know who to contact at Microsoft to discuss this product?

  • Connection error in java website. Tnsping shows that the service is running

    - by user1439090
    I have a java website application running in windows 7 which uses oracle database for its functionalities. The database has default SID name orcl. When I use tnsping, I can see that the orcl service is active. Also most of the application is working fine except for one part.

  • XPath find element based on ancestor element

    - by martymcfly
    Hi, again I have Java AST which is created from public class Test { String o = new String("hh"); public void wrong1() { synchronized(o) { // huhu } } } I try to create a XPath query which finds the synchronized block in which the defined String variable o is used. As the definition is above it is an ancestor of the SynchronizedStatement, but I dont get it working //SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image=ancestor::ClassOrInterfaceBody[ClassOrInterfaceBodyDeclaration/FieldVariableDeclaratorId/@Image]]] I know that /SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image= is correct, my problem is how to address the ancestor ClassOrInterfaceBody part. Hope its clear what i mean ;-) Thanks

  • Sql Server Select Command and too much data sent to winforms application

    - by ThanosPapathanasiou
    When you have an application and send a select command, the sql server gathers all the data and sends them back to your application and fills your datagrid (for example) If you performed the same select command in sql management studio, immediately as the query starts running and finding data the results panel would start filling with the data found. How can I do that for my winforms application? Is there a technique or a standard method of doing something like this? Links to good examples would be an immense help. thanks

  • MVC model flow?

    - by fuzzygoat
    I am setting up an application using the MVC model and I have a query regrading the flow of information from the UI to the data model. What I need to do is place data from the UI in the model, what I have done is write a method in the view which collects the required data in an object and then passes it to the model. The model then takes ownership of the data so that the view can release its ownership. Does this sound sensible?

  • Count number of queries executed by NHibernate in a unit test

    - by Bittercoder
    In some unit/integration tests of the code we wish to check that correct usage of the second level cache is being employed by our code. Based on the code presented by Ayende here: http://ayende.com/Blog/archive/2006/09/07/MeasuringNHibernatesQueriesPerPage.aspx I wrote a simple class for doing just that: public class QueryCounter : IDisposable { CountToContextItemsAppender _appender; public int QueryCount { get { return _appender.Count; } } public void Dispose() { var logger = (Logger) LogManager.GetLogger("NHibernate.SQL").Logger; logger.RemoveAppender(_appender); } public static QueryCounter Start() { var logger = (Logger) LogManager.GetLogger("NHibernate.SQL").Logger; lock (logger) { foreach (IAppender existingAppender in logger.Appenders) { if (existingAppender is CountToContextItemsAppender) { var countAppender = (CountToContextItemsAppender) existingAppender; countAppender.Reset(); return new QueryCounter {_appender = (CountToContextItemsAppender) existingAppender}; } } var newAppender = new CountToContextItemsAppender(); logger.AddAppender(newAppender); logger.Level = Level.Debug; logger.Additivity = false; return new QueryCounter {_appender = newAppender}; } } public class CountToContextItemsAppender : IAppender { int _count; public int Count { get { return _count; } } public void Close() { } public void DoAppend(LoggingEvent loggingEvent) { if (string.Empty.Equals(loggingEvent.MessageObject)) return; _count++; } public string Name { get; set; } public void Reset() { _count = 0; } } } With intended usage: using (var counter = QueryCounter.Start()) { // ... do something Assert.Equal(1, counter.QueryCount); // check the query count matches our expectations } But it always returns 0 for Query count. No sql statements are being logged. However if I make use of Nhibernate Profiler and invoke this in my test case: NHibernateProfiler.Intialize() Where NHProf uses a similar approach to capture logging output from NHibernate for analysis via log4net etc. then my QueryCounter starts working. It looks like I'm missing something in my code to get log4net configured correctly for logging nhibernate sql ... does anyone have any pointers on what else I need to do to get sql logging output from Nhibernate?

  • Create a user-defined aggregate without SQL CLR

    - by David Pfeffer
    I am planning on deploying a database to SQL Azure, so I cannot use the SQL CLR. However, I have a need to create an aggregate function -- in my case, I need to STUnion a bunch of Geography objects together. (Azure is expected to support Spatial by June.) Is there another way to accomplish this, without making use of the CLR, in a query? Or do I have to create a UDF that will take a table as a parameter and return the aggregate?

  • ASP.NET MVC & EF4 Entity Framework - Are there any performance concerns in using the entities vs retrieving only the fields i need?

    - by Ant
    Lets say we have 3 tables, Users, Products, Purchases. There is a view that needs to display the purchases made by a user. I could lookup the data required by doing: from p in DBSet<Purchases>.Include("User").Include("Product") select p; However, I am concern that this may have a performance impact because it will retrieve the full objects. Alternatively, I could select only the fields i need: from p in DBSet<Purchases>.Include("User").Include("Product") select new SimplePurchaseInfo() { UserName = p.User.name, Userid = p.User.Id, ProductName = p.Product.Name ... etc }; So my question is: Whats the best practice in doing this? == EDIT Thanks for all the replies. [QUESTION 1]: I want to know whether all views should work with flat ViewModels with very specific data for that view, or should the ViewModels contain the entity objects. Real example: User reviews Products var query = from dr in productRepository.FindAllReviews() where dr.User.UserId = 'userid' select dr; string sql = ((ObjectQuery)query).ToTraceString(); SELECT [Extent1].[ProductId] AS [ProductId], [Extent1].[Comment] AS [Comment], [Extent1].[CreatedTime] AS [CreatedTime], [Extent1].[Id] AS [Id], [Extent1].[Rating] AS [Rating], [Extent1].[UserId] AS [UserId], [Extent3].[CreatedTime] AS [CreatedTime1], [Extent3].[CreatorId] AS [CreatorId], [Extent3].[Description] AS [Description], [Extent3].[Id] AS [Id1], [Extent3].[Name] AS [Name], [Extent3].[Price] AS [Price], [Extent3].[Rating] AS [Rating1], [Extent3].[ShopId] AS [ShopId], [Extent3].[Thumbnail] AS [Thumbnail], [Extent3].[Creator_UserId] AS [Creator_UserId], [Extent4].[Comment] AS [Comment1], [Extent4].[DateCreated] AS [DateCreated], [Extent4].[DateLastActivity] AS [DateLastActivity], [Extent4].[DateLastLogin] AS [DateLastLogin], [Extent4].[DateLastPasswordChange] AS [DateLastPasswordChange], [Extent4].[Email] AS [Email], [Extent4].[Enabled] AS [Enabled], [Extent4].[PasswordHash] AS [PasswordHash], [Extent4].[PasswordSalt] AS [PasswordSalt], [Extent4].[ScreenName] AS [ScreenName], [Extent4].[Thumbnail] AS [Thumbnail1], [Extent4].[UserId] AS [UserId1], [Extent4].[UserName] AS [UserName] FROM [ProductReviews] AS [Extent1] INNER JOIN [Users] AS [Extent2] ON [Extent1].[UserId] = [Extent2].[UserId] LEFT OUTER JOIN [Products] AS [Extent3] ON [Extent1].[ProductId] = [Extent3].[Id] LEFT OUTER JOIN [Users] AS [Extent4] ON [Extent1].[UserId] = [Extent4].[UserId] WHERE N'615005822' = [Extent2].[UserId] or from d in productRepository.FindAllProducts() from dr in d.ProductReviews where dr.User.UserId == 'userid' orderby dr.CreatedTime select new ProductReviewInfo() { product = new SimpleProductInfo() { Id = d.Id, Name = d.Name, Thumbnail = d.Thumbnail, Rating = d.Rating }, Rating = dr.Rating, Comment = dr.Comment, UserId = dr.UserId, UserScreenName = dr.User.ScreenName, UserThumbnail = dr.User.Thumbnail, CreateTime = dr.CreatedTime }; SELECT [Extent1].[Id] AS [Id], [Extent1].[Name] AS [Name], [Extent1].[Thumbnail] AS [Thumbnail], [Extent1].[Rating] AS [Rating], [Extent2].[Rating] AS [Rating1], [Extent2].[Comment] AS [Comment], [Extent2].[UserId] AS [UserId], [Extent4].[ScreenName] AS [ScreenName], [Extent4].[Thumbnail] AS [Thumbnail1], [Extent2].[CreatedTime] AS [CreatedTime] FROM [Products] AS [Extent1] INNER JOIN [ProductReviews] AS [Extent2] ON [Extent1].[Id] = [Extent2].[ProductId] INNER JOIN [Users] AS [Extent3] ON [Extent2].[UserId] = [Extent3].[UserId] LEFT OUTER JOIN [Users] AS [Extent4] ON [Extent2].[UserId] = [Extent4].[UserId] WHERE N'userid' = [Extent3].[UserId] ORDER BY [Extent2].[CreatedTime] ASC [QUESTION 2]: Whats with the ugly outer joins?
