pub struct MergePlanClause {
pub kind: MergeClauseKind,
pub extra_predicate: Vec<Filter>,
pub action: MergePlanAction,
}Expand description
A single WHEN ... THEN ... arm within a SqlPlan::Merge.
Fields§
§kind: MergeClauseKindThe kind of match this arm fires on.
extra_predicate: Vec<Filter>Optional extra predicate (the AND <pred> part), evaluated against
the joined row pair after the match condition is satisfied.
action: MergePlanActionThe action to apply when this arm fires.
