根据某字段分组，获取当前数据成功或失败各自的统计数

1、单独获取失败或成功的数据，并根据areaCode分组很好写：

SELECT p2.areaCode,COUNT(1) FROM vrv_paw_rulestatus p2 WHERE executeResult=1 GROUP BY p2.areaCode

2、如果要根据areaCode分组获取失败的和成功的统计，在一条数据里，就需要一定的技巧在里面：

SELECT a.code,
(SELECT COUNT(1) FROM vrv_paw_rulestatus p2 WHERE executeResult=1 and p2.areaCode = p.areaCode ) AS count_0,
(SELECT COUNT(1) FROM vrv_paw_rulestatus p2 WHERE executeResult=0 and p2.areaCode = p.areaCode ) AS count_1 
FROM vrv_paw_area a LEFT JOIN vrv_paw_rulestatus p ON p.areaCode=a.code 
where 1=1 
GROUP BY a.code

　　public List<Object[]> queryBaseLineGroup(String areaCode, String startIP, String endIP) {
        StringBuffer hql = new StringBuffer("SELECT a.code,"
                + "(SELECT COUNT(1)  FROM vrv_paw_rulestatus p2 WHERE executeResult=1 and p2.areaCode = p.areaCode ) AS count_0  "
                + "FROM vrv_paw_area a LEFT JOIN vrv_paw_rulestatus p ON p.areaCode=a.code  where 1=1 ");
        if (StringUtils.isNotBlank(areaCode)) {
            hql.append(" AND a.code =\'"+areaCode+"\'");
        }
        hql.append("GROUP BY a.code ");
                
        List<Object[]> list = getSession().createSQLQuery(hql.toString()).list();
        return list;
    }
