A quick T-SQL/SSMS trick that I know and love is the ability to add text to multiple lines at a time. I tend use macros in Notepad++ to accomplish these types of repetitive actions but this type of work can be completed in SSMS.
Annoyingly, this doesn’t work quite the same way in VS Code or Azure Data Studio. Alt + Down moves a line down one, Alt + Shift + Down copies the current line. To replicate this behavior in VS Code / Azure Data Studio, hold down Alt + Shift and use the mouse to select the lines you want.
