How can I restore a SQL database from a transaction log?
To restore a SQL database from a transaction log, you need to have a full backup of the database and the transaction log file. You can use the RESTORE command in SQL Server.
What is the syntax for the RESTORE command?
The syntax is: RESTORE DATABASE database_name FROM DISK = 'backup_file.bak' WITH NORECOVERY; RESTORE LOG database_name FROM DISK = 'log_file.trn' WITH RECOVERY;
What does the NORECOVERY option do?
The NORECOVERY option allows you to apply additional transaction logs after the full backup. It keeps the database in a restoring state.
Can I restore only specific transactions from the log?
Yes, you can use point-in-time recovery to restore the database to a specific moment, but it requires careful management of your log backups.
