Microsoft sql server ошибка 948

Yesterday I installed SQL Server 2008 on my laptop (Windows 7 64 bit), I need to attach a .mdf to the server, but when I try to do this, I get this error:

Attach Database failed for server ‘prince/sqlexpress’ (Microsoft.SqlServer.smo)

ADDITIONAL INFORMATION:
1.An Exception Occured while executing a Transact Sql statement or Batch (Microsoft.SqlServer.connectioninfo)

2.Unable to open the Physical file Operating system error 5: «5(Access is denied.)». (Microsoft SQL Server, Error: 5120)

With the help of Internet, I found some solution.

1.Start SQL Server manager as Administrator (right-click on the program, choose «Start as administrator»):

But I still got the same error.

That .mdf file does have have permission, so I moved into external drive (pendrive because my system have only C:\ drive, yet no partition I have done ) .

Then I got another error,

Attach database failed for Server ‘Prince\SQLEXPRESS’.
(Microsoft.SqlServer.Smo) ADDITIONAL INFORMATION:

An exception occurred while executing a Transact-SQL statement or
batch. (Microsoft.SqlServer.ConnectionInfo)

The database ‘Databasename’ cannot be opened because it is version
655. This server supports version 611 and earlier. A downgrade path is not supported. Could not open new database ‘Databasename’. CREATE
DATABASE is aborted. (Microsoft SQL Server, Error: 948)

I use the Query —

«select @@version;»

I got the Output as

«Microsoft SQL Server 2005 — 9.00.3042.00 (Intel X86) Feb 9 2007

Now, how to fix microsoft sql server error 948 or how to solve microsoft sql server error 948? Keep reading…

Reading sql server error log location from SQL Query

Identifying SQL Server Error Log File used by SQL Server Database Engine can be done by reading SQL Server Error Logs. DBA can execute the XP_READERRORLOG extended stored procedure to read the SQL Server Error Log and search for its location used by the instance of SQL Server.

USE master
Go
xp_readerrorlog 0, 1, N'Logging SQL Server messages in file', NULL, NULL, N'asc'
Go

The parameters for XP_READERRRORLOG are:
1. Value of error log file we would like to read. values are 0 = current, 1 = last one before current, 2 = second last before current etc…
2. Log file type:- 1 or NULL = error log, 2 = SQL Agent log
3. Search string 1:- String one you want to search for
4. Search string 2:- String two you want to search for to further refine the results
5. start time for Search
6. end time for search
7. Sort order for search results:- N’asc’ = ascending, N’desc’ = descending

By default, we have 6 Server Error Logs kept but we can increase the number of SQL Server Error Logs from the default value of six.

Solution for Resolving the Error

This error is expected when we try to attach file from higher version of SQL Server to lower version of SQL. We cannot attach/detach or backup/restore a database from a newer version of SQL Server down to an older version. This is because they have a different internal file structures which does not support backwards compatibility.

Here is what I was able to find on the internet.

For more build details go to “https://sqlserverbuilds.blogspot.com/2014/01/sql-server-internal-database-versions.html”

For example in simple words say:

You are trying to restore/attach database/backup which been created with SQL Server 2008, but the actual version of SQL Server you are trying to attach it to is SQL Server 2005.

Here solution would be  : you are trying to attach a 2008 Database (655) to a 2005 instance (611); that cannot work, obviously. so solutions are:

– either update your 2005 instance to a 2008 one

– or install another instance on the same server (a 2008 one)

– or use any other server which has 2008 already installed.
