From: Warren Young Date: July 16 2007 7:05pm Subject: Single-parameter tquery with SQLQueryParms fixed List-Archive: http://lists.mysql.com/plusplus/6820 Message-Id: <469BC17E.5090401@etr-usa.com> MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit I believe I've found the proper fix for this problem. In the Query methods that execute queries (execute(), store*(), use()) that take a SQLQueryParms reference, add this line above the call to the other overload: AutoFlag<> af(def.processing_); This is for v2.3. svn has the fix for v3 now already.
