OffsetWindowFunction

alopex_sql::planner::logical_plan

Struct OffsetWindowFunction 

Source 
pub struct OffsetWindowFunction {
    pub value: TypedExpr,
    pub offset: Option<TypedExpr>,
    pub default: Option<TypedExpr>,
}
Expand description

Arguments shared by the positional LAG and LEAD window functions.

Offset and default expressions are evaluated against the current row. The value expression is evaluated against the addressed partition row. Unlike aggregate windows, these functions do not restrict lookup to the current aggregate frame.
