---------------------------------------
Jan, is it possible for you to test using the rename statement so that we can resolve this as a doc issue?
> 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.
