documentation:

--- Connects two `DBAction`s.
--- When executed this function will execute the first `DBAction`
--- and then execute the second applied to the result of the first action.
--- A database error will stop either action.
--- @param x - The `DBAction` that will be executed first
--- @param y - The `DBAction` hat will be executed afterwards
--- @return A `DBAction` that wille execute both `DBAction`s.
--- The result is the result of the second `DBAction`.
