Examples of easyJ.database.session.Session.query()

easyJ.database.session.Session.query()
此方法用来对数据进行查询 @param className String 进行查询的数据库表对应的类 @param condition String 进行查询的条件里面是直接执行的条件语句，用的是数据库字段名而不是属性名，例如：student_name like '%liu%' @param orderbyClauses String 进行排序的语句，用的也是数据库字段名，例如：order by student_name @param currentPageNo int 用来标识需要的第几页数据 @throws EasyJException @return Page 返回符合条件的处于第currentPageNo页的数据。

        clazz = object.getClass();
        SelectCommand scmd = DAOFactory.getSelectCommand(clazz);
        Filter filter1 = DAOFactory.getFilter("roleId", SQLOperator.EQUAL,
                creatorId);
        scmd.setFilter(filter1);
        ArrayList creators = session.query(scmd);
        String creatorName = "";
        if (creators.size() > 0) {
            Role creator = (Role) creators.get(0);
            creatorName = creator.getRoleName();
        }
