Documentation

litExpr :: Sql DBType a => a -> Expr a Source #

Produce an expression from a literal.

Note that you can usually use lit, but litExpr can solve problems of inference in polymorphic code.

slitExpr :: Nullity a -> TypeInformation (Unnullify a) -> a -> Expr a Source #

sparseValue :: Nullity a -> TypeInformation (Unnullify a) -> Row a Source #
