Toad is flagging function REGEXP_LIKE as a syntax error "The XML was improperly formatted. Please escape it if necessary" (4310949)

Function REGEXP_LIKE was introduced in DB2 11.1. When using it in a sql statement, Toad is flagging it as an error:

Example:

SELECT NAME, SURNAME FROM TBO.PERSON
WHERE REGEXP_LIKE(SURNAME, 'Mor+?icone')

Toad flags with error "The XML was improperly formatted. Please escape it if necessary"

WORKAROUND

The statement will execute. No, workaround is required

STATUS

Waiting for fix in a future release of Toad for DB2
