I have tried in several ways to add the
Debug button to my SSMS but not successful.
Is there a way to add the
Debug button to SSMS v18?
Debugger is deprecated in SSMS18 as @LowlyDBA said in his answer.
For those who look for an alternative, you can use SSDT/Visual Studio to debug a query.
From the SQL menu
From the Drop down list next to the execute icon in the query window
From the context menu in the query wondow
