日時の形式で日付を持つテーブルがあります。
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)

このテーブルのデータを使用して、列名がまったく同じであるが日付が切り捨てられた (および変更を反映するためにカウントが変更された) 集計日の日付テーブルを作成したいのですが、必要なデータを切り捨てる選択クエリを最初に特定しました。
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>
次に、その選択クエリを使用して新しいテーブルにデータを入力しようとしましたが、切り捨てられた日付は挿入されませんでした。むしろ、元の日付が挿入されました。
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)

次に、新しいテーブルにデータを入力するためにデータを別の名前に変更しようとしましたが、それでも完全な日付がテーブルに挿入されました。
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>
挿入の名前を変更しようとしましたが、新しいテーブルのフィールドではない名前に落ちました:
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>
私は何が欠けていますか？切り捨てられた集計データを新しいテーブルに挿入するにはどうすればよいですか?

2013-06-11 23:00:00 が 2013-06-11 00:00:00 に変更されたように見えるため、dataType A に問題がある可能性があります
