improve transaction handling in procedures ------------------------------------------ Key: TEIID-2641 URL: https://issues.jboss.org/browse/TEIID-2641 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.6 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Critical Fix For: 8.4.1, 8.5 Atomic blocks do not have well-defined handling w.r.t. variable assignments and the implicit return cursor. In both cases the affects are currently non-atomic - the last assignment/cursor is effective even. Also exception handling in an atomic block must result in an exception being thrown to guarantee the entire block atomicity.
