Ever since VS Code and Azure Data Studio came out, people have been asking for SQL Prompt to port over. I’ve been right there with you, though unsure of the value, given how UI dependent Prompt is for users.
Things have changed.
There’s an EAP program, with an early look at the formatting part of Prompt in ADS.
I’ve been using this for a few weeks, and it’s different, but it works well. All my styles from SSMS are ported and linked, and it’s a quick set of keystrokes, albeit different ones, to format code.
I’m curious to see what others think, so join the program if you want formatting in ADS and are willing to give some feedback.
