Struct mz_expr::WindowFrame
source · pub struct WindowFrame {
pub units: WindowFrameUnits,
pub start_bound: WindowFrameBound,
pub end_bound: WindowFrameBound,
}
Expand description
Describe a window frame, e.g. RANGE UNBOUNDED PRECEDING
or
ROWS BETWEEN 5 PRECEDING AND CURRENT ROW
.
Window frames define a subset of the partition , and only a subset of window functions make use of the window frame.
Fields§
§units: WindowFrameUnits
ROWS, RANGE or GROUPS
start_bound: WindowFrameBound
Where the frame starts
end_bound: WindowFrameBound
Where the frame ends
