#0407 – SQL Server – Clearing out the list of servers in SSMS


Today, I will talk about a very common question that I see in the forums. When you  work with a lot of SQL Server instances, the list of servers seen on the login screen in the SQL Server Management Studio (SSMS) becomes quite long, raising the question:

How to clear out the list of SQL Server instance names in SSMS?

SQL Server 2014 and above

Clearing out servers that no longer exist or to which you no longer need to connect to is quite simple in SQL Server 2014 and above. All you need to do is:

  1. Open SSMS
  2. In the login window,  expand the list of available SQL Server instances
  3. Use the keyboard’s down arrow or use the mouse to scroll down to the instance that needs to be deleted
  4. Once the required instance is selected in the list, just press “Delete” on the keyboard
SSMS_LoginWindow

Just select the appropriate SQL Server instance and press “Delete” to remove it from the SSMS login history

If you are still using an older version of SSMS due to various reasons, there is a manual workaround to this as shown below.

SSMS for SQL Server 2012 and below

  1. Close all open instances of SSMS on your workstation
  2. Depending upon your version of the SSMS client tools, navigate to and delete the files as shown in the table below:
  3. Launch SSMS
  4. It might take a little while to launch, as it recreates the “SqlStudio.bin”/”mru.dat
    • Once launched, you will see that the entire SSMS history is gone
SSMS Client Tools Version Path File to Delete
SQL 2012 %USERPROFILE%AppDataRoamingMicrosoftSQL Server Management Studio11.0 SqlStudio.bin
SQL 2008 %USERPROFILE%AppDataRoamingMicrosoftMicrosoft SQL Server100ToolsShell SqlStudio.bin
SQL 2005 %USERPROFILE%AppDataRoamingMicrosoftMicrosoft SQL Server90ToolsShell mru.dat

Until we meet next time,

Be courteous. Drive responsibly.

Showing how to debug a DML trigger by stepping into a DML trigger during a SSMS T-SQL Debugging session

#0382 – SQL Server – SSMS – Debugging a T-SQL DML Trigger


I often receive questions related to debugging code using SSMS. Based on these questions, I have written a lot of blog posts in the past, however I was recently asked the question:

How can I debug a DML trigger in SSMS?

I realized that while I had encountered the same question and researched it in my initial days (when I worked on SQL Server 2000), I had never written about it. So, here goes.

In order to demonstrate how to debug a trigger, all we need to do is debug the statement that initiates the trigger.

For this demonstration, I will fire an update on the [Sales].[SalesOrderHeader] table of the AdventureWorks database.

USE AdventureWorks2012;
GO
UPDATE soh
SET soh.SubTotal += 2
FROM Sales.SalesOrderHeader AS soh
WHERE soh.SalesOrderNumber = 'SO43697';

When we debug this query (using F10), the SSMS debugger launches and we can step through the code using the same key combinations as we have in Visual Studio.

Debugging T-SQL script using SSMS

Executing the update should fire the DML trigger [uSalesOrderHeader] which can be debugged like any other T-SQL code by stepping into the trigger (press F11 when executing the update).

That’s it. Debugging a trigger is no different than debugging a stored procedure or any other T-SQL script.

In case you would like to learn more about debugging in SSMS, please do refer my previous posts (links below). If there is anything specific that you would like to know more about, do drop in a line.
