executeQuery(expression: Object io): Boolean;
The executeQuery method of the JadeRelationalQueryProviderIF interface is called by the ODBC driver to execute a query. The expression parameter that is passed is the value of the expression created by the final call to the application implementation of the binaryExpression method or the unaryExpression method.
Your implementation of this method must delete any transient or persistent objects used in defining the expression. The implementation can delete the object before returning to the ODBC driver.
