newtype QGenExpr context syntax s t

The type of lifted beam expressions that will yield the haskell type t.

context is a type-level representation of the types of expressions this can contain. For example, QAggregateContext represents expressions that may contain aggregates, and QWindowingContext represents expressions that may contain OVER.

syntax is the expression syntax being built (usually a type that implements IsSql92ExpressionSyntax at least, but not always).

s is a state threading parameter that prevents QExprs from incompatible sources to be combined. For example, this is used to prevent monadic joins from depending on the result of previous joins (so-called LATERAL joins).

class Typeable context => AggregateContext context

Typeclass for all haskell data types that can be used to create a projection in a SQL select statement. This includes all tables as well as all tuple classes. Projections are only defined on tuples up to size 5. If you need more, follow the implementations here.
