今天给大家介绍如何查询系统中的WTPart对象

 

public static WTPart getPart(String num){
        if(num == null || num.trim().length()==0){
            return null ;
        }
        WTPart part = null ;
        try {
            QuerySpec qs = new QuerySpec(WTPart.class) ;
            qs.appendWhere(new SearchCondition(WTPart.class,WTPart.NUMBER,SearchCondition.EQUAL,num),new int[] {0}) ;
            QueryResult qr = PersistenceHelper.manager.find((StatementSpec)qs) ;
            //过滤最新版本
            LatestConfigSpec ls = new LatestConfigSpec() ;
            QueryResult qrLs;
            qrLs = ls.process(qr);
            System.out.println(qrLs.hasMoreElements()) ;
            while(qrLs.hasMoreElements()){
                part = (WTPart) qrLs.nextElement() ;
            }
        } catch (WTException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return part ;
    }
