Set BIND VARIABLE and EXECUTE QUERY programmatically in ADF

A very common scenario in ADF is to set a bind variable and execute query programmatically within AMImpl/ VOImpl classes. Here's a simple way to do this: To set bind variable for all rowsets:       ViewObjectImpl someVO = this.getSomeViewObject();       VariableValueManager vMngr = someVO.ensureVariableManager();        vMngr.setVariableValue("DefinedBindVariable",value);        someVO,executeQuery(); To set bind variable for default rowset:          ViewObjectImpl someVO = this.getSomeViewObject();          someVO.setNamedWhereClauseParam("DefinedBindVariable",value);          someVO,executeQuery();
