Just a comment about Duncan's code:  if the last three parameters are OUT
parameters, shouldn't the execute() method be called as :

mysql->execute(QueryTemp.in(), resout.out(), updatecount.out(),
corbawarnout.out());

to insure that memory is released by the _var variables before the call is
made?
