java执行sql server存储过程,数据为空时报错列名无效

kingoneyun 2015-09-21 04:56:46
在我的项目里碰到一个很奇怪的问题,用Java代码执行sql server存储过程的时候,某一条查询语句查询数据为空时,Java代码中报错“XXX列名无效“,但是在数据库中查询时不报错?而且更奇怪的是因为项目分不同的角色,所以数据库有多个,同样的SQL语句在一个库中报错,而另外的库中不报错?

以下我的sql语句片段:

SELECT DISTINCT * INTO #table_cycle FROM(
SELECT cp.popdb_id, cp.pop_id, cp.pop, cp.address,
c.city,c.city_e,d.district,d.district_e ,
ch.channel,isnull(ch.channel_e,'') as channel_e,cha.chain,isnull(cha.chain_e,'') as chain_e,
isnull(cp.contact_person, '') as contact_person,
isnull(cp.contact_telephone, '') as contact_telephone,
isnull(cp.contact_mobile, '') as contact_mobile, cp.status,CAST (cp.pop AS nvarchar(256)) AS abbr
, pdc.Longitude,pdc.Latitude,2015 AS client_year
,9 AS client_period ,c.City_ID,d.District_ID,ch.Channel_ID,cha.Chain_ID,38 AS calendar_week,cp.client_id
,pf.Prefecture,pf.Prefecture_e,pf.Prefecture_id,pv.Province,pv.Province_e,pv.Province_id,c.country_id
,d.City_id AS district_city_id,d.Country_id AS district_country_id
,ch.Channel_order,cp.photo,null as user_id,cp.Comments as Comments
,pc.pop_cluster,pc.pop_cluster_e
FROM dbo.Client_POPDB cp
INNER JOIN (SELECT [value] AS POPDB_ID FROM [dbo].[f_split] ('3286',',')) t
ON t.POPDB_ID=cp.POPDB_id

inner join city c on c.city_id=cp.city_id
left join district d on d.district_id=cp.district_id
left join channel ch on ch.channel_id=cp.channel_id
left join chain cha on cha.chain_id=cp.chain_id
LEFT JOIN dbo.Prefecture pf ON c.Prefecture_id=pf.Prefecture_id
LEFT JOIN dbo.Province pv ON pv.Province_id=pf.Province_id
inner join popdb_coordinate pdc on cp.popdb_id = pdc.popdb_id
and pdc.Longitude is not null and pdc.Latitude is not null
left join pop_cluster pc on cp.client_id=pc.client_id and cp.pop_cluster_id=pc.pop_cluster_id
WHERE cp.Client_id=1 AND cp.Relevant=1
) temp

select cpc.client_id,cpc.popdb_id,cpc.contact_id,cpc.user_id,cpc.create_date,cpc.update_date
from client_popdb_contact cpc
where cpc.client_id=1 and cpc.popdb_id in (select popdb_id from #table_cycle)


字段在表里面都有,两个数据库,一个库可以用,另外的一个就不行!也不知道为什么


Java执行代码:

StringBuffer sql = new StringBuffer();

sql.append(" DECLARE @d DATETIME ");
sql.append(date == null ? " set @d = GETDATE() ":" set @d = '"+date+"' " );
sql.append(" exec Mobile_get_cycle_pop_2_daily_pop_rs"+test+" "+user_id+", @d,"+client_id+","+popdb_ids).append("\n");
cn = com.tpm.util.DBUtils.cn();
stmt = cn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery(sql.toString());
while (rs.next()) {
String contact_client_id = rs.getString("client_id");
String popdb_id = rs.getString("popdb_id");
String contact_id = rs.getString("contact_id");
String contact_user_id = rs.getString("user_id");
String create_date = rs.getString("create_date");
String update_date = rs.getString("update_date");


}

rs.close();

是不是要判断一下,返回的结果集是否为null。

结果集判断null在rs.next()会判断吧,而且在之前测试的时候也加过null的判断,在结果集中的第一个结果有值,但是第二个结果没值的情况下,rs.next()还是会进入到while循环里面rs.getString("client_id")就会报列名无效的错误
