[Haskelldb-users] Sorting by the result of an expression

[GrayShade <gra...@gm...>]

Is there any way to do something like
		order [desc t (constant date' .-. date)]

in HaskellDB (i. e. sorting by an expression, not by a column).

Thanks.

There isn't. You can create a column containing the expression you'd like to
sort by, though.
