Hi Jamie, is there an "oficial" document about SQL good practices?

select all not best practice, better to select all columns.

Asterix is a no and where clause order as been mentioned i would say is best practice. i will also say some of the comments are rude. we are all learning so lets keep them nice and constructive

This is exactly as my solution except i never us * as it is intensive on the server. I either use an abertary value to return or an actual colomn. good work!

becuase you are only intersted in two movies stars. the query has to have both stars in it.
