hello :) watching your course on Udemy (also wrote it there) -
I want to see the original create view that the user made (not the table that was created, using the select statement: SELECT * FROM view_name)
I tried to use 'SHOW CREATE VIEW view_name', but that doesn't work. How can I see it?
thank you!
