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 ;    }
