如何創建一個新的MySQL表作爲主表中字段的子集？

Question

我有一個約30個字段的MySQL表。我需要創建一個包含這些字段子集的第二個表格，再加上CURDATE（）來跟蹤他們的支出歷史記錄。我得到的語法錯誤，但也許我的方法是不正確的開始。請檢查此，謝謝！

INSERT INTO history (customer_id, name, amount, date_recorded) 
set date_recorded = CURDATE() 
SELECT customer_id, name, amount 
FROM master; 

什麼我試圖在MySQL做在上面的例子是從主客戶列表複製CUSTOMER_ID，名稱，數量的領域，包括今天的日期。對於歷史表中的記錄佈局是在這裏：

+---------------+------------------+------+-----+---------+----------------+ 
| Field   | Type    | Null | Key | Default | Extra   | 
+---------------+------------------+------+-----+---------+----------------+ 
| id   | int(10) unsigned | NO | PRI | NULL | auto_increment | 
| customer_id | int(11)   | NO | PRI | NULL |    | 
| name   | varchar(255)  | NO |  | NULL |    | 
| amount  | int(11)   | NO |  | NULL |    | 
| date_recorded | date    | NO |  | NULL |    | 
+---------------+------------------+------+-----+---------+----------------+ 

Answer 1

試試這個::

INSERT INTO history (customer_id, name, amount, date_recorded) 

SELECT customer_id, name, amount, CURDATE() 
FROM master 

另一種方式是::

INSERT INTO history (customer_id, name, amount, date_recorded) 

SELECT customer_id, name, amount, DATE(now()) 
FROM master
