Struct postgres_parser::nodes::RowMarkClause

RowMarkClause parser output representation of FOR [KEY] UPDATE/SHARE clauses

Query.rowMarks contains a separate RowMarkClause node for each relation identified as a FOR [KEY] UPDATE/SHARE target. If one of these clauses is applied to a subquery, we generate RowMarkClauses for all normal and subquery rels in the subquery, but they are marked pushedDown = true to distinguish them from clauses that were explicitly written at this query level. Also, Query.hasForUpdate tells whether there were explicit FOR UPDATE/SHARE/KEY SHARE clauses in the current query level.

Fields

rti: Index

strength: LockClauseStrength

waitPolicy: LockWaitPolicy

pushedDown: bool
