How to Check Database Logs in SQL Server Manually

The standard manual methods for viewing the SQL transaction log files

Method 1

View Transaction Log SQL Server Management Studio (SSMS)

1. Install and Open the SQL Server Management Studio (SSMS) software.

2. Now, connect to the SQL Server window, enter the Server's name and type of authentication, and enter connect.

3. In the Object Explorer, visit the Management to check the log files.

4. Now, move to SQL Server Logs Option

5. Now, Right-click on SQL Server logs and select View>> SQL Log.

6. Last, complete log details are viewed on the Log File Viewer window. We can select different logs like the SQL Server Agent and Database Mail in these.

Method 2

Use SQL Function fn_dblog to View SQL Transaction Log

The SQL function fn_dblog is used to take out information from the transaction log files.

Step 1 First, create the SQL database named "Emp_T". Preview the data records in it using a query.

SELECT * FROM Emp_T;

Step 2 Now, alter the records in the table using the UPDATE command.

UPDATE Emp_T SET DEPARTMENT = "Sales" WHERE Emp_Name = "Trump"

Step 3 Now, once again, review the table using the SELECT query. All the changes can be visible in it.

SELECT * FROM Emp_T

Step 4 Now, execute the fn_dblog function according to the requirement. Run the query to check the time of the updated operation.

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

Step 5 Analyze all the logs, such as Insert, Delete, and so on.

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