问题 Is using SQL Express in a production environment a reasonable choice? I looked at Microsoft's comparison chart: http://www.microsoft.com/sql/prodinfo/features/compare-features.mspx I would be using SQL Express with a small to mid-sized web site. I don't believe I would exceed the 4GB database size limit. Is SQL Express typically supported in shared hosting environments? Is there something I'm missing that would make SQL Express an unreasonable choice? 回答1: I know many people using SQL Express

问题 I'm using Sqlserver express and I can't do before updated trigger. There's a other way to do that? 回答1: MSSQL does not support BEFORE triggers. The closest you have is INSTEAD OF triggers but their behavior is different to that of BEFORE triggers in MySQL. You can learn more about them here, and note that INSTEAD OF triggers "Specifies that the trigger is executed instead of the triggering SQL statement, thus overriding the actions of the triggering statements." Thus, actions on the update

问题 I am deploying sql express with my application. I will like that database engine to accept remote connections. I know how to configure that manual by launching the sql server configuration manager, enabling tcp/ip connections, specifying the ports etc.. I am wondering if it will be possible to do the same thing from the command line. Or maybe I will have to create a "SQL Server 2008 Server Project" in visual studio. EDIT 1 I posted the same question in here but I will like to do the same

问题 In my Win 7 development machine, and in order to use SQL Express instance instead of the localDB installed by default. I unchecked "Use IIS Express" in my MVC 4 project properties page (Web tab), then I got the following error: ASP.NET 4.5 has not been registered on the Web server. You need to manually configure your Web server for ASP.NET 4.5 in order for your site to run correctly. I verified that ASP.NET is activated within the IIS features. Please what could be done to resolve this? 回答1:

问题 I am using SQL Server Express 2008 R2 and I wanted to change the instance name from "machine name"\SQLEXPRESS2008R2 to just "machine name". I ran: sp_dropserver 'old_name' go sp_addserver 'new_name', 'local' go Then restarted the SQL Service. Now when I look at Select @@SERVERNAME --this is correct But this isn't correct?

问题 I've started work on a project that requires an SQL Server Database. I will be building a front end application in c# .Net 3.5, that will use LINQ to SQL. I need to host the database on a network share so that a group of users can all gain access to the database, mainly for read only. I know that SQL Server Compact is designed to run on the local machine and my company is not willing to front the costs of a full blooded SQL Server. Is there a way of achieving what I need to do via SQL Server

问题 The MSDN documentation for SQLEXPRESS says: When an application first establishes a connection from a running instance of SQL Server Express, SQL Server Express will automatically attach an .mdf file. When the user closes the application, SQL Server Express detaches the .mdf file from the instance. This does not appear to be happening. If I replace the MDF file with a new one of the same name (after deleting the log file, of course) SQL Server Express will refuse to attach it. I've tried just
