from :: forall f q fields sql. ToFrom f q fields => Resume q (From f fields E) sql => f -> q -> sql

FROM accepts the following sources

• Tables
• Inner and outer joins
• Aliased tables
• Aliased SELECT statements

Due to how SQL binding works, joins and subqueries require brackets to be parsed correctly. For example:

• SELECT column FROM (SELECT column FROM table) AS alias should be select column # from (select column # from table # as alias))
• SELECT column FROM table alias JOIN other_table other_alias should be select column # from ((table # as alias)join(other_table # as other_alias)))

To aid composition, SELECT projections are only validated on FROM

investigate :: forall b a. Warn "Debug.Trace usage" => Show a => a -> b -> b

Once in a while, we all need to debug. A lot of programmers from imperative languages find real trouble with debugging, as they can't just bung in a console.log to see values. Well, what if I told you... you can! So, we can cheat a little bit, and use some escape hatches in the Debug package, including traceShow, which will log anything Showable. With this function, we can show a value at any point, and return anything!
