问题 This is strange as I'm able to connect to localDB through SSMS 2008R2 with the same connection string (" Data Source=(LocalDB)\v11.0;Integrated Security=true ") Only C# code is unable to connect, I have tried increasing login time with Connect Timeout=60 but no luck. I have also tried specifying the database Initial Catalog=<databasename> where the <databasename> is the one I have created on localdb via ssms. Any pointers as to why is this not connecting? 回答1: Any chance it is because you

问题 I installed LocalDb using the SqlLocalDb.msi package and I can connect to it using SSMS using the server name (LocalDb)\v11.0 . So far so good.

由 戏子无情 提交于 2019-11-26 18:19:09
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.

Please what could be done to resolve this? Maybe you have to execute the following in the Visual Studio Tools command prompt: aspnet_regiis -i You can

Connecting to SQL Server LocalDB using JDBC

由 扶醉桌前 提交于 2019-11-26 16:37:39
Is it possible to connect to a SQL Server LocalDB using JDBC? It appears that (as of Dec 2011) it was not possible. Do you know of a workaround or change in status? Is it possible to connect to a SQL Server LocalDB using JDBC? Not with Microsoft's JDBC Driver. The jTDS JDBC driver supports named pipes. Executing SqlLocalDB.exe info MyInstance will get you (along with other info) the instance pipe name such as "np:\.\pipe\LOCALDB#F365A78E\tsql\query". Do you know of a workaround or change in status? Possible workarounds are using alternative JDBC drivers or switching to SQL Server 2012 Express

If I have to work with localdb , do we need to install it separately? I have SQL Server 2008 R2 Management Studio installed, SQL Server 2012 installed, .net 4.0.2 update installed. But I don't see localdb in the PC yet. Andrey Morozov From MSDN The primary method of installing LocalDB is by using the SqlLocalDB.msi program. LocalDB is an option when installing any SKU of SQL Server 2012 Express. Select LocalDB on the Feature Selection page during installation of SQL Server Express . There can be only one installation of the LocalDB binary files for each major SQL Server Database Engine version
