How do I check SQL Server Logs? Manually

The two manual methods to check SQL Server Logs using the SSM and fn_dblog with their detailed steps.

Using SQL Server Management Tool (SSMS)

If the user wants to check SQL Server log files manually, then the first method is used of SSMS.

After that change the table data using the UPDATE command, for this run this query.

UPDATE EMP SET DEPARTMENT = ‘ IT’ WHERE EMP_NAME = ‘ RAM’

Now, repeat the view command using the SELECT command. Now, changes can be seen in the modified table

Execute the fn_dblog function according to the requirements.

Select [Begin Time], [Transaction Name] from fn_dblog(null, null) where [Transaction Name] = ‘ Update’

Lastly, check the logs such as insert, update, etc. by executing this query

SELECT [Begin Time], [Transaction Name] from fn_dblog(null, null)

Drawbacks of Manual Solutions
