如何逐步修复SQL Server 2012

SQL database corruption refers to the corruption of the MDF or NDF files of the database. Hence, to repair SQL Server 2012, you will need to repair the MDF/NDF file of the respective database.

Step 1. Stop the MS SQL Server service.

Press "Windows + R" and type services.msc.

Find and double-click "SQL Server (Instance Name)".

In the Properties window, click "Stop" to stop the SQL Server, and then click "Apply" to confirm the change.

Step 2. Launch the SQL repair tool. In the main interface, click "Browse" (the two dots) to select the corrupted MDF/NDF file. Then click "Repair" to initiate the analysis of your MDF/NDF file.

If you know the exact location of the file, click "Browse" to locate the database.

If you're unsure of the file location, click "Search" to locate the .mdf or .ndf file.

Step 3: Once done, you'll see all database objects listed in the left pane of the window. Select the database objects you wish to repair and click "Export".

Step 4: Select your preferred method to export the database data: "Export to Database" or "Export as SQL Scripts". If you choose "Export to Database", you'll need to further specify the server information, log in to your account, and select a target database, either a new one or an existing one.

Step 5. Before clicking "OK", you need to restart the SQL Server.

Press "Windows + R" and type services.msc.

Find and double-click "SQL Server (instance name)".

In the Properties window, click "Start" to restart the SQL Server service, and then click "Apply" to confirm the changes.

Step 6. Click "OK" to save the repaired files to your desired SQL database.

Additional Tip: How to Repair SQL Server 2012 Using the DBCC Command

DBCC CHECKDB checks both the logical and physical integrity of all objects in a specified database. Utilizing the DBCC command is another option for repairing your SQL Server 2012. The command is quite straightforward:

DBCC CHECKDB ('DatabaseName')

Upon executing this command, it will check for any consistency errors and, if possible,修复 them.

如何防止SQL数据库损坏

除了学习如何修复 SQL Server 2012 之外，了解如何防止数据库损坏也非常重要。以下是一些建议：

Always monitor your disk counters

Occasionally detect database errors by running DBCC CHECKDB

However, sometimes SQL database corruption can occur beyond your control. Therefore, it's essential to have a permanent solution like an SQL repair tool, such as MS SQL Recovery, installed on your computer. This will significantly reduce the risk of data loss.
