Dax,
I was not able to find an answer to your question in our documentation, so we followed up with the primary developer for QueryBuilder, who provided the following information:
Hi, Dax,
I spoke with the developer again, and, prior to his first response, he had tested the escape capability on SQLServer, where it worked as expected. This time, however, he tried it on Oracle, and he had the same experience as you. So, we’ve uncovered a bug, and I created an SPR with a 10.0 MOR targeted for the Oracle-specific fix.
Thanks for your patience, and for your help in identifying the problem.
Regards,
Jane
