As we all know, Microsoft released MS SQL Server 29 years ago i.e. SQL Server 1.0 and for ages, it has reached many milestones with its ease of use and security. It has grabbed its own space in online markets with lightning speed over the years. The latest version was released in 2017 i.e. SQL Server 2017 which also supports Linux platforms as well such as Red Hat Enterprise Linux, Ubuntu, SUSE Linux Enterprise & Docker Engine.

MS SQL Server is a management system for storing and extracting data from the connected application. Though the most widely used secure and safe database server, it is also prone to unexpected errors. One such error is “SQL Error 3414” –

SYMPTOMS of the Error 3414:

The error is caused when the SQL Server service does not start during login or startup of database recovery. Hence, the database fails to retrieve causing MSSQL error code 3414.

retrieve causing MSSQL error code 3414

The extended form of the error written to ERRORLOG or Windows Application Event Log with EvenetID-3414 with SQL Server is as follows:

“Error: 3414, Severity: 21, State: 1.
An error occurred during recovery, preventing the database ‘mydb’ (database ID 13) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support)”

Usually, an error that precedes Error 3414 in the ERRORLOG or Event Log is the reason for SQL database recovery failure.

Also, the status of the database is set to SUSPECT. The SUSPECT status is reflected in SQL Server Management Studio and sys.databases.state_desc. If you try to operate the database in this state you might encounter “SQL suspect database error 926” as follows:

“Msg 926, Level 14, State 1, Line 1
Database ‘mydb’ cannot be opened. It has been marked SUSPECT by recovery. See the SQL Server errorlog for more information”

Understand the Primary Cause of the Error 3414

The basic cause of the occurrence of error 3414 is due to the same SPID value in the server log file with the failure in the recovery of the database file. Go through the following checksum error that occurred during the time of the “read page” operation in the database to roll forward a transaction.

“2010-03-31 17:33:13.00 spid15s Error: 824, Severity: 24, State: 4.
2010-03-31 17:33:13.00 spid15s SQL Server detected a logical consistency-based I/O error: (bad checksum). It occurred during a read of page (0:-1) in database ID 13 at offset 0x0000000000b800 in file ‘C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\DATA\mydb_log.LDF’. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
2010-03-31 17:33:13.16 spid15s Error: 3414, Severity: 21, State: 1.
2010-03-31 17:33:13.16 spid15s An error occurred during recovery, preventing the database ‘mydb’ (database ID 13) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support”

Resolution to Fix “Error Code 3414” in SQL Server?

The best possible solution to resolve the SQL Server error 3414 is to restore the database from a backup (if available) using SQL Server Management Studio. It is a good practice to take timely backups for handling unexpected disastrous situations. But, there are times when it is not possible to recover from a backup of the database or incomplete data is restored from your available backup. Here are the following methods to fix the error:

Method 1: Use DBCC CHECDB for emergency repair

Executing DBCC CHECDB should be your first step to get back the database to running state.

[ ( database_name | database_id | 0
) ]
[ , MAXDOP = number_of_processors ]

However, it the best method but transactional consistency is not guaranteed since recovery failed. There are no ways to find out which transactions were rolled back or rolled forward and not allowed due to recovery failure.

Method 2: Copy Entire (healthy or recoverable data) Database to another Database

If the first workaround method fails to work, then you must try to copy all the possible data that is in the healthy or recoverable state to another database. To do this, set the database in emergency mode with the help of the given command:


After setting emergency mode, you can try to copy or move all the data to another database.

Resolve with Automated Method – SQL Database Recovery
