mysql : 필드를 자르고 다른 테이블의 데이터를 집계합니다.

Question

날짜가 시간 형식으로되어있는 테이블이 있습니다.

mysql> select * from topsmsspammers_hour limit 1; 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| date    | spam | suspect | clean | spammer  | spam_campaign_id       | messageType | policy | isSenderPolicy | 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| 2013-06-11 23:00:00 | 1 |  0 |  0 | +12073708065 | NotSet|Message35392HerbisReallyWorkingRealy |   4 |  1 |    1 | 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
1 row in set (0.00 sec) 

mysql> 

내가 (그리고 카운트 변경 사항을 반영하도록 변경) 동일한 열 이름 만 잘립니다 날짜를 집계 일 날짜의 테이블을 채우는 데이 테이블의 데이터를 사용하려면이 내가 먼저 선택 쿼리를 확인

mysql> select SUBSTRING_INDEX(date, ' ', 1) as date, sum(spam) as spam, sum(suspect) as suspect, sum(clean) as clean, spammer, spam_campaign_id, messageType, policy, isSenderPolicy from topsmsspammers_hour group by date, spammer, spam_campaign_id, messageType, policy, isSenderPolicy limit 1; 
+------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| date  | spam | suspect | clean | spammer  | spam_campaign_id       | messageType | policy | isSenderPolicy | 
+------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| 2013-06-11 | 1 |  0 |  0 | +12073708065 | NotSet|Message35392HerbisReallyWorkingRealy |   4 |  1 |    1 | 
+------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
1 row in set, 1 warning (1.66 sec) 

mysql> 

내가 다음 새 테이블을 채우는 것을 선택 쿼리를 사용하려고하지만 잘립니다 날짜가 삽입되지 않은 : 그 내가 필요한 데이터를자를 것이다. 오히려 원래의 날짜가 삽입 :

mysql> insert into topsmsspammers_day (date, spam, suspect, clean, spammer, spam_campaign_id, messageType, policy, isSenderPolicy) select SUBSTRING_INDEX(date, ' ', 1) as date, sum(spam) as spam, sum(suspect) as suspect, sum(clean) as clean, spammer, spam_campaign_id, messageType, policy, isSenderPolicy from topsmsspammers_hour group by date, spammer, spam_campaign_id, messageType, policy, isSenderPolicy limit 1; 
Query OK, 1 row affected, 1 warning (1.68 sec) 
Records: 1 Duplicates: 0 Warnings: 1 

mysql> select * from topsmsspammers_day limit 1;                +---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| date    | spam | suspect | clean | spammer  | spam_campaign_id       | messageType | policy | isSenderPolicy | 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| 2013-06-11 00:00:00 | 1 |  0 |  0 | +12073708065 | NotSet|Message35392HerbisReallyWorkingRealy |   4 |  1 |    1 | 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
1 row in set (0.00 sec) 

mysql> 

나는 테이블에 삽입하기 다음 새 테이블을 채우기위한 다른 이름을 가지고 데이터를 변경하지만 여전히 전체 날짜 결과 시도 :

mysql> insert into topsmsspammers_day (date, spam, suspect, clean, spammer, spam_campaign_id, messageType, policy, isSenderPolicy) select SUBSTRING_INDEX(date, ' ', 1) as dayDate, sum(spam) as spam, sum(suspect) as suspect, sum(clean) as clean, spammer, spam_campaign_id, messageType, policy, isSenderPolicy from topsmsspammers_hour group by dayDate, spammer, spam_campaign_id, messageType, policy, isSenderPolicy limit 1; 
Query OK, 1 row affected (1.75 sec) 
Records: 1 Duplicates: 0 Warnings: 0 

mysql> select * from topsmsspammers_day limit 1; 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| date    | spam | suspect | clean | spammer  | spam_campaign_id       | messageType | policy | isSenderPolicy | 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
| 2013-06-11 00:00:00 | 1 |  0 |  0 | +12073708065 | NotSet|Message35392HerbisReallyWorkingRealy |   4 |  1 |    1 | 
+---------------------+------+---------+-------+--------------+---------------------------------------------+-------------+--------+----------------+ 
1 row in set (0.00 sec) 

mysql> 

난 삽입에 이름을 변경하려하지만 새 테이블의 필드되지 않는 이름을 넘어 :

mysql> insert into topsmsspammers_day (dayDate, spam, suspect, clean, spammer, spam_campaign_id, messageType, policy, isSenderPolicy) select SUBSTRING_INDEX(date, ' ', 1) as dayDate, sum(spam) as spam, sum(suspect) as suspect, sum(clean) as clean, spammer, spam_campaign_id, messageType, policy, isSenderPolicy from topsmsspammers_hour group by dayDate, spammer, spam_campaign_id, messageType, policy, isSenderPolicy limit 1; 
ERROR 1054 (42S22): Unknown column 'dayDate' in 'field list' 
mysql> 

내가 무엇을 놓치고? 잘린 집계 된 데이터를 새 테이블에 삽입하려면 어떻게합니까?

2013년 6월 11일 23시 0분 0초이 2013년 6월 11일 00:00:00으로 변경 한 것 같습니다 그래서 아마 그것 dataType와
