Class TargetRelation

Object

gudusoft.gsqlparser.ir.semantic.TargetRelation

public final class TargetRelation
extends Object

Slice 78 — write-side target of an INSERT INTO target SELECT ... statement. Carries the target table's binding plus the verbatim column spellings the SQL author wrote in the INSERT column list (e.g. INSERT INTO target (a, b) ... → ["a", "b"]).

Empty columns means the surface SQL omitted the column list (e.g. INSERT INTO target SELECT ...). The IR does NOT positionally expand the catalog's columns into this list — the source SELECT's output names are the lineage endpoints, and consumers that want catalog-mapped target column names can join with the supplied Catalog.

This type is intentionally a 2-field value object so the IR's navigation stays simple (StatementGraph.getTarget() is null or a struct). Other INSERT facets (OUTPUT clause, RETURNING, ON CONFLICT, partition spec) are out of slice-78 scope and stay rejected via existing diagnostics.

Method Detail

getBinding
