Enum mz_sql::plan::expr::WindowFrameUnits
source · pub enum WindowFrameUnits {
Rows,
Range,
Groups,
}
Expand description
Describe how frame bounds are interpreted
Variants§
Rows
Each row is treated as the unit of work for bounds
Range
Each peer group is treated as the unit of work for bounds, and offset-based bounds use the value of the ORDER BY expression
Groups
Each peer group is treated as the unit of work for bounds. Groups is currently not supported, and it is rejected during planning.
