External Materialization MySQL can't swap primary and stage table in xa transaction ----------------------------------------------------------------------------------- Key: TEIID-4579 URL: https://issues.jboss.org/browse/TEIID-4579 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 8.12.7.6_3 Reporter: Jan Stastny Assignee: Steven Hawkins When using MySQL 5.5 as materialization target (primary and stage table are placed there) and on server side the mysql datasource is configured as xa-datasource, problem with transaction scope and status appears. The cause of this issue is, that in my "teiid_rel:MATVIEW_AFTER_LOAD_SCRIPT" I try to swap primary and stage materialization tables by using third swap table: {code:sql} exec Source.native(''ALTER TABLE DV_MATVIEWS_MAT_VIEW_STAGE RENAME TO DV_MATVIEWS_MAT_VIEW_TEMP''); exec Source.native(''ALTER TABLE DV_MATVIEWS_MAT_VIEW RENAME TO DV_MATVIEWS_MAT_VIEW_STAGE''); exec Source.native(''ALTER TABLE DV_MATVIEWS_MAT_VIEW_TEMP RENAME TO DV_MATVIEWS_MAT_VIEW''); {code} but there is a limitation of ALTER TABLE commands which results in implicit commit: https://dev.mysql.com/doc/refman/5.5/en/implicit-commit.html Eventually the first of the three ALTER commands succeeds, but the second fails, thus I end up with no DV_MATVIEWS_MAT_VIEW_STAGE table, as it was previously renamed to DV_MATVIEWS_MAT_VIEW_TEMP. This particular problem could be resolved by TEIID-4240 I believe.
