How to Repair SQL Server 2019: Database in Suspect Mode

A database going into a suspect mode is usually caused by an abnormal shutdown, hardware failure, or corrupted transaction logs. Steps to repair SQL Server mode in suspect mode include:

Attempt automatic repair: First try to restart the SQL Server service, sometimes the system will automatically try to repair the database.

Use emergency mode: If automatic repair does not work, you can set the database to emergency mode to allow access. This usually requires editing the SQL Server startup parameters directly to add the -f flag to start the SQL Server instance.

DBCC CHECKDB: Once the database is accessible, run the DBCC CHECKDB command to check the logical and physical consistency of the database and repair it based on the output recommendations.

Backup and restore: Before any repair operation, restoring the database from a recent full backup, if possible, is the safest solution. Ensure regular database backups to avoid data loss.
