Struct MergeIntoClauseNode 

pub struct MergeIntoClauseNode {
    pub kind: i32,
    pub predicate: Option<LogicalExprNode>,
    pub action: Option<MergeIntoActionNode>,
}

A single WHEN clause within a MERGE INTO statement.

Fields

kind: i32

predicate: Option<LogicalExprNode>

Optional AND <expr> predicate. Absent when the clause has no predicate.

action: Option<MergeIntoActionNode>
