Invalid examples in readme

[gabbhack]

SQL queries must be with sql prefix, but they are not. Example:

ponairi/readme.md

Lines 57 to 61 in 9130428

	echo db.find(Order, "SELECT * FROM Order WHERE customer = ?", john.id)
	# Option[T] can also be used if the query mighn't return anything
	import std/options
	assert db.find(Option[Order], "SELECT * FROM Order WHERE customer = 99999").isNone
