Usage

Example

Opening an OAdvise object:

// create a database

ODatabase odb("ExampleDB", "scott", "tiger");

// create a dynaset

ODynaset thedynaset(odb, "select * from emp");

// default constructor of OAdvise

OAdvise adv1;

// open that advisory, attaching it to dynaset

adv1.Open(thedynaset);
