From 484c026f59f4fbbef10b1a4aad54c3872da05705 Mon Sep 17 00:00:00 2001 From: Jeff Jensen Date: Tue, 4 Aug 2026 21:03:52 -0500 Subject: [PATCH] fix(dataset): Fix NoSuchColumnException in CompositeTable.getValue CompositeDataSet merges same-named tables from separate datasets (e.g. two flat-XML files both inserting into the same table) into a single CompositeTable that exposes only the first part's metadata. Reading a column that a later part never itself declared threw NoSuchColumnException instead of being treated as not supplied, surfacing through InsertOperation's core insert path via equalsIgnoreMapping/getIgnoreMapping. * CompositeTable.getValue() now resolves such a column to ITable.NO_VALUE for that part's rows - the same sentinel InsertOperation already uses to omit a column from a generated statement - instead of letting the part's own NoSuchColumnException propagate. * Add CompositeTableTest, InsertOperationTest, and InsertOperationIT regression coverage; all three reproduce the original stack trace when the fix is reverted.

When production code does not guarantee row insertion order (e.g. Hibernate reordering a batch insert), the database's generated-ID assignment order then diverges from the data-content order, misaligning same-data rows and failing the comparison despite both sides holding identical data. Add VerifyTableDefinition#sortOnFilteredColumnsOnly (default false, preserving prior behavior), implementing the opt-in toggle proposed in issue 676: when true, both tables sort by only their excludeColumns/includeColumns-filtered columns instead of by all native columns. + + Fix NoSuchColumnException when two same-named tables merged by CompositeDataSet (e.g. from two separate flat-XML datasets both inserting into the same table) disagree on columns. A row belonging to a part that never declared an optional column crashed instead of being treated as not supplied, hitting InsertOperation's core insert path via equalsIgnoreMapping/getIgnoreMapping.
