Entities represent the actual tables/views being selected. Typically, something like:
comes from something like:`Map(Entity("People", Nil), Ident("p"), Property(Ident(p), "name"))`.When you define aquerySchema, the fields you mention inside becomePropertyAliass. For example something like:`querySchema[Person]("t_person", _.name -> "s_name")`Becomes something like:`Entity("t_person", List(PropertyAlias(List("name"), "s_name"))) { def renameable = Fixed }`Note that Entity has an Opinion calledrenameablewhich will be the valueFixedwhen aquerySchemais specified. That means that even if theNamingSchemaisUpperCase, the resulting query will selectt_personas opposed toT_PERSONorPerson.SELECT p.name FROM People psomething like:`Map(Entity("People", Nil), Ident("p"), Property(Ident(p), "name"))`.When you define a `querySchema`, the fields you mention inside become `PropertyAlias`s. For example something like:`querySchema[Person]("t_person", _.name -> "s_name")`Becomes something like:`Entity("t_person", List(PropertyAlias(List("name"), "s_name"))) { def renameable = Fixed }`Note that Entity has an Opinion called `renameable` which will be the value `Fixed` when a `querySchema` is specified. That means that even if the `NamingSchema` is `UpperCase`, the resulting query will select `t_person` as opposed to `T_PERSON` or `Person`.
