• SQL SERVER - Detecting non-indexed columns but used in WHERE clause

  - by Vadi

  How to detect a column included in WHERE clause but used in indexed? Little Background: Until the time the table has few number of records things will be okay, once it started having millions of records then index should be created for a column which is used in WHERE clauses in stored procs, inline queries etc., Since we have hundreds of stored procs and queries that often gets changed by the devs I wanted to have a automated way of identifying those columns that are used in WHERE clauses but not an index is created. How to do that in SQL SERVER 2008?

• Unresponsive Clojure REPL after exception

  - by Hendekagon

  If I start a REPL and then do something that throws an exception like (use 'non-existent-thing) ** then after that the REPL ceases to evaluate anything I enter. Is there a special key I can press to make it turn round, face me, uncross its arms and listen once more ? Or must I ctrl-d, restart, type everything up to where I was and get it right this time ? ** which results in: Exception in thread "Thread-1" java.lang.RuntimeException: java.io.FileNotFoundException: Could not locate non_existent_thing__init.class or non_existent_thing.clj on classpath: (NO_SOURCE_FILE:0)

It's almost like it is not the focused control. it is the only view in the app. How can I ensure that the first time the UIWebView is touched it responds?

• Count white spaces to the left of a line in a text file using C++

  - by insertable

  Hi all, I am just trying to count the number of white spaces to the LEFT of a line from a text file. I have been using count( line.begin(), line.end(), ' ' ); but obviously that includes ALL white spaces to the left, in between words and to the right. So basically what I'm wanting it to do is once it hits a non-space character stop it from counting the white spaces. Thanks everyone.

• linq to sql with nservicebus table lock issue

  - by IGoor

  I am building a system using NServiceBus and my DataLayer is using Linq 2 SQL. The system is made up of 2 services. Service1 receives messages from NSB. It will query Table1 in my database and inserts a record into Table1 If a certain condition is met a new NSB message is sent to the 2nd service Service2 will update records also in Table1 when it receives messages from Service1 and it does some other non database related work. Service2 is a long running process. The problem I am having is the moment Service2 updates a record in Table1, the table is locked. The lock seems to be in place until Service2 has completed all it is processing. i.e. The lock is not released after my datacontext is disposed. This causes the query in Service1 to timeout. Once Service2 completes processing, Service1 resumes processing again without problem. So for example Service1 code may look like: int x =0; using (DataContext db = new DataContext()) { x = (from dp in db.Table1 select dp).Count(); // this line will timeout while service2 is processing Table1 t = new Table1(); t.Data = "test"; db.Table1.InsertOnSubmit(t); db.SubmitChanges(); } if(x % 50 == 0) CallService2(); The code in service2 may look like: using (DataContext db = new DataContext()) { Table1 t = db.Table1.Where(t => t.id == myId); t.Data = "updated"; db.SubmitChanges(); } // I would have expected the lock to have been released at this point, but this is not the case. DoSomeLongRunningTasks(); // lock will be released once service2 exits I don't understand why the lock is not released when the datacontext is disposed in Service2. To get around the problem I have been calling: db.ExecuteCommand("SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED"); and this works, but I am not happy using it. I want to solve this problem properly. Has any one experienced this sort of problem before and does any one know how to solve it? Why is the lock not released after the datacontext has been disposed? Thanks in advance. p.s. sorry for the extremely long post.

• Are There Any 3rd-Party Free Deployment Templates for Visual Studio Express Edition

  - by Peter Lee

  Hi, Due to the lack of Deployment functionality of Visual Studio Express edition, I'm here asking if anyone can recommend a very nice free Deployment template for the express edition. I'm mainly working with C# desktop project. I know that there is still ClickOnce deployment in the Express edition, but it seems to me that it is not so difficult to control, which means, you do "click once", then the tool will give you a bunch of files out of my control, not so easy to maintain. Thanks. Peter
