Mysql 配置单元使用子查询填充表

我正在开发一个Hadoop数据库，使用Hive作为首选接口。我希望能够将多个SELECT语句组合成一个查询（有点像UNION，但每个查询填充不同的列）。下面的查询将在单个列中返回我需要的所有结果，但我希望能够使用每个查询填充单个列。任何关于如何实现这一点的帮助都将是非常棒的——某种等同于价值观的蜂巢可能会做到这一点。干杯

INSERT OVERWRITE TABLE tstr_tmp SELECT * FROM
(SELECT time_stamp FROM http WHERE ext_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'http://lucy.info' ORDER BY time_stamp asc limit 1) as last_visit_of_day
UNION ALL 
SELECT * FROM (SELECT CAST(COUNT(hr) as string) FROM http WHERE ext_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'http://lucy.info' group by  ext_url) as n_hour_bins
UNION ALL
SELECT * FROM (SELECT time_stamp FROM http WHERE ext_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'http://lucy.info' ORDER BY time_stamp desc limit 1) as first_visit_of_day
UNION ALL
SELECT * FROM (SELECT ext_url FROM http  WHERE ext_url = 'http://lucy.info' group by ext_url) as domain_name
UNION ALL
SELECT * FROM (SELECT CAST(count(*) as string) FROM http WHERE ext_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'http://lucy.info' group by ext_url) as n_http_requests
UNION ALL
SELECT * FROM (SELECT int_ip FROM http WHERE ext_hostname = 'exotichorse' group by int_ip) as internal_ip;

按照下面的要求，每个查询将以字符串形式返回单个值。对于这个特定的查询集，将返回以下结果：

00:08:00
2
07:00:00
http://lucy.info
2
192.168.0.22

我正在处理一个数据库，该数据库将告诉我有关用户流量的信息，因此该子集将填充下表

CREATE TABLE metric_http_domain_time_summary( last_visit_of_day string, n_hour_bins string, first_visit_of_day string, domain_name string, n_http_requests string, internal_ip string) PARTITIONED BY (dt string, hr string, origin string, cl string, st string);

我知道我需要对输入的数据进行分区，但我对这一点相当有信心，一旦我成功地运行了未分区的查询，就会对其进行编辑。我的能力差距在于将子查询串在一起以填充一个表。

在离开并思考了很长一段时间后，我找到了答案。工会是没有必要的，而且实际上是在阻挠。此查询将根据需要返回上述输出。如果其他人也有同样的问题，我会让它继续存在。由于堆栈溢出声誉的限制，我不得不去掉ext_url，但是这个概念会起作用

SELECT * FROM
(SELECT time_stamp FROM http WHERE referrer_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'ext_url_here' ORDER BY time_stamp asc limit 1) as last_visit_of_day,
(SELECT CAST(COUNT(hr) as string) FROM http WHERE referrer_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'ext_url_here' group by  ext_url) as n_hour_bins,
(SELECT time_stamp FROM http WHERE referrer_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'ext_url_here' ORDER BY time_stamp desc limit 1) as first_visit_of_day,
(SELECT ext_url FROM http  WHERE ext_url = 'http://lucy.info' group by ext_url) as domain_name,
(SELECT CAST(count(*) as string) FROM http WHERE referrer_hostname = 'exotichorse' AND dt = '01/07/2015' AND ext_url = 'ext_url_here' group by ext_url) as n_http_requests,
(SELECT int_ip FROM http WHERE referrer_hostname = 'exotichorse' group by int_ip) as internal_ip;
