I thought there is some problem in connection Strings but for me everything looks fine, and my question how to fix this problem?
Answers:
Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.
Method 1
Version 706 is a database file from Sql Server 2012
Version 665 is a database file from Sql Server 2008R2 (post SP1 ?)
http://conceptdev.blogspot.com/2009/04/mdf-cannot-be-opened-because-it-is.html
Method 2
Here is Tested Solution, 1st Connect both Server in your SQL Server Management Studio and then RUN the 1st Code Block
--1st Run this (One Time) EXEC sp_addlinkedserver @server='YOUR_SERVER_IP', -- here you can specify the name of the linked server @srvproduct='', @provider='sqlncli', -- using SQL Server Native Client @datasrc='YOUR_SERVER_IP', -- add here your server name @location='', @provstr='', @catalog='DATABASE_NAME'
Then Run this Individually
SELECT TOP(100) * FROM LOCAL_TABLE A, [YOUR_SERVER_IP].DATABASE_NAME.dbo.TABLE_NAME C WHERE A.ID=C.ID
Method 3
If you’re trying to attach to a local db use LocalDb (since vs2012, sql2012), ie:
Data Source=(LocalDB)v11.0;AttachDbFilename= (etc)
Method 4
I’m sure the problem was that aspnetdb.mdf can’t open.
Sometimes this file gets corrupted. The problem was that I can’t validate login page.
After deleting(and replacing) my login form control, the problem was solved.
The reason for this was because control from asp.net uses aspnet membership. I replaced my login control (with javascript) with CSS style and remove all related files and that solved it.
I hope this helps someone.
