LSN is Log Sequence Number, it is used to maintain and store the database activity like insert, delete, update, etc. to retrieve deleted tables in SQL Server using this method, you need to follow the steps listed below:
Step 1: Firstly, create an SQL database using the query
USE [master]; GO CREATE DATABASE RecoverDeletedTables; GO USE RecoverDeletedTables; GO CREATE TABLE [Employees] () [Sr.No] INT IDENTITY, [Date] DATETIME DEFAULT GETDATE (), [City] CHAR (25) DEFAULT ‘City1’);
Step 2: Then, the next step is to recover deleted table in SQL Server using the LSN method, the user needs to insert the data into SQL.
USE RecoverDeletedTables; GO INSERT INTO Employees DEFAULT VALUES; GO 100

USE RecoverDeletedTables Go DELETE Employees WHERE [Sr.No] < 10 GO Select * from Employee
Step 4: To recover deleted table in SQL Server, we need to get information about the deleted rows first.
USE RecoverDeletedTables GO SELECT [Current LSN], [Transaction ID], Operation, Context, AllocUnitName FROM fn_dblog(NULL, NULL) WHERE Operation = ‘LOP_DELETE_ROWS’
Step 5: Retrieve the LSN of the LOP_BEGIN_XACT log record in SQL Server.
USE RecoverDeletedTables GO SELECT [Current LSN], Operation, [Transaction ID], [Begin Time], [Transaction Name], [Transaction SID] FROM fn_dblog(NULL, NULL) WHERE [Transaction ID] = ‘0000:0000030e’ AND [Operation] = ‘LOP_BEGIN_XACT’

–Restoring Full backup with norecovery. RESTORE DATABASE RecoverDeletedTables_COPY FROM DISK = ‘C:\Program Files\Microsoft SQL Server\MSSQL10_50.TESTDB\MSSQL\Backup\RecoverDeletedTables.bak’ WITH MOVE ‘RecoverDeletedTables’ TO ‘C:\Program Files\Microsoft SQL Server\MSSQL10_50.TESTDB\MSSQL\Backup\RecoverDeletedTables.mdf’, MOVE ‘RecoverDeletedTables_log’ TO ‘C:\Program Files\Microsoft SQL Server\MSSQL10_50.TESTDB\MSSQL\Backup\RecoverDeletedTables.ldf’, REPLACE, NORECOVERY; GO –Restore Log backup with STOPBEFOREMARK option to recover exact LSN. RESTORE LOG RecoverDeletedTables_COPY FROM DISK = N’C:\Program Files\Microsoft SQL Server\MSSQL10_50.TESTDB\MSSQL\Backup\RecoverDeletedTables_tlogbackup.trn’ ITH STOPBEFOREMARK = ‘lsn:0x00000015:0000002a:0001’
