…MySQL supports views, so you can save a query as…a view, and use that view like you would a subselect.…This is really very simple.…For this example, we'll use the database.…And here's a useful little query that gets the as minutes and seconds I can say…SELECT ID, album_id, title, track_number.…And duration DIV 60 AS minutes.…
And duration MOD 60 as seconds FROM track.…And when I run this, you'll see we have the entire track table.…And instead of the duration as a number…of seconds we've got it in minutes and seconds.…And that's actually pretty useful.…Now if I know I'm going to use this query a lot, I can save it as a view.…I can simply do this.…I can say CREATE VIEW.…And name it trackView.…
And then here's just an overloading of the as keyword.…As.…And this is the view itself.…I like to put the semicolon on a separate line when I indent like that.…It's just me, it's not necessary.…And now I can say select asterisk FROM TrackView,…as if it were a table, or a sub select.…I press Go.…I've got exactly the same result, but now I have got it as a trackView.…
