You should not use the _out types. They are internals helpers that
application code should never use directly.

Also, you should not make pointers to _var types -- that defeats the
point of them which is that they release whatever they are holding
when they go out of scope. Your call should look something like

  SQLStatement_var mysql = ...;
  ResultSets_var resout;
  UpdateCounts_var updatecount;
  CorbaSQLWarnings_var corbawarnout;

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


Get "Advanced CORBA Programming with C++" and read all the stuff about
memory management.

Cheers,

Duncan.
