• Disk errors or faulty storage devices.
• Sudden power failure or system shutdown.
• Improper termination of Access operations.
• Access database files that have nearly reached their limit.
• Multiple-user access permissions create conflicts.
• Network interruptions while working on the database.

Different Methods to Repair Access Database from Command Line!

We have tried several solutions and found only the given ones working for us. So, try them individually to get the appropriate solutions based on your situations.

Method 1. Compact and repair Access database from command line

The first method is a compact and repair utility that helps you fix minor corruptions by rebuilding indexes and reclaiming unused spaces. Here are the detailed steps:

C:\Program Files\Microsoft Office\Office16\
C:\Program Files (x86)\Microsoft Office\OfficeXX\

Step 2. Access Command Prompt and Run as Administrator.

Step 3. Execute the repair command to fix the database file.

“C:\Path\To\MSACCESS.EXE” “C:\Path\To\Database.accdb” /compact

Step 4. Wait for the process to complete.

Step 5. Once done, check the repaired database objects.

Method 2. Fix Access Database Using Decompile Switch

Another top method is the decompile switch. It removes all the compiled VBA code from the database and fixes corruption related to broken VBA modules, startup crashes, and logic level errors.

Step 1. Access Command Prompt and enter the given cmdlet.

“C:\Path\To\MSACCESS.EXE” “C:\Path\To\Database.accdb” /decompile

Step 2. Open the database files once the decompiling is completed.

Step 3. Press Alt+ F11 keys and click on Debug> Compile.

Step 4. The process rebuilds the VBA code properly.

Method 3. Automate Compact & Repair via Batch File

You can use this method to automate the maintenance or management of the multiple database files. Here’s how:

Step 1. Access Notepad and add the provided command.

“C:\Path\To\MSACCESS.EXE” “C:\Path\To\Database.accdb” /compact

Step 2. Save the file and name it repair_access.bat.

Step 3. Run the file manually or schedule it using the Task Scheduler.

Step 4. This will help you automate the repair process.

Method 4. Repair Database File without Access application (VBA -based)

The VBA automation method is useful to repair database files without loading the full interface. Here are the detailed steps:

Note: The method requires the installation of Microsoft Access on the system.

Step 1. Create a New Blank Database

• Open the Access application and make a new Blank database.
• Save the file with a name and don’t import or link any objects.
• This newly created database will act as a repair controller.

Step 2. Access the VBA Editor

• Press Alt+F11 to open the VBA Editor.
• Tap on Insert to select the Module.
• A new blank module will appear on the screen.

Step 3. Insert the VBA Repair Code

Paste the following code in the new module window.

Sub RepairAccessDatabase()
Dim sourceDB As String
Dim repairedDB As String
‘ Path of the corrupted database
sourceDB = “C:\Path\To\Corrupted\Database.accdb”
‘ Path for the repaired database
repairedDB = “C:\Path\To\Repaired\Database_Repaired.accdb”
‘ Perform Compact and Repair
Application.CompactRepair _
SourceFile:=sourceDB, _
DestinationFile:=repairedDB, _
LogFile:=False
MsgBox “Database repair completed successfully.”, vbInformation
End Sub

Step 4. Update the File Paths

• Replace the sourceDB with the corrupted database file path.
• Replace repairedDB with the saving location.
• It will save the repaired version of the database file without interfering with the original one.

Step 5. Run the VBA Macro

• Place the cursor inside the macro.
• Press F5 or click Run to proceed.
• Wait till the process is completed.
• It will generate the repaired database file after the successful completion.

Step 6. Verify the Repaired Database

• Close the VBA Editor.
• Access the repaired database file.
• Check the database objects like tables, records, queries, forms, relationships and reports are intact.
