Description

A trigger like, where V, V1 and V2 are columns of type XML will thrown an exception when fired.

CREATE TRIGGER AIS AFTER INSERT ON T_MAIN
REFERENCING NEW_TABLE AS N
FOR EACH STATEMENT
INSERT INTO T_ACTION_STATEMENT(A, V1, ID, V2)
SELECT 'I', V, ID, V FROM N

ERROR 38000: The exception 'java.sql.SQLException: An attempt was made to get a data value of type 'java.lang.Object' from a data value of type 'XML'.' was thrown while evaluating an expression.

Most likely because triggers are implementing using VTIs and hence JDBC ResultSets and XML is not supported through JDBC yet.

TriggerTest shows this issue, see the comment with the bug number to reproduce.
