pub struct NestedLoopJoinNode { /* private fields */ }

Nested loop join: for each outer row, scans all inner rows testing condition.

Supports all join types and arbitrary join conditions.

Implementations

impl NestedLoopJoinNode

pub fn new( outer: Box<dyn PlanNode>, inner: Box<dyn PlanNode>, condition: Option<Expr>, join_type: JoinType, ) -> Self
