SQL在查詢后插入表中

Question

所以我不確定如何處理這個問題。 我有一個看起來像這樣的表[在這里輸入圖像描述] [1]

！[1]： https ： //i.stack.imgur.com/k9Cl7.png

我需要從不同的表中獲取信息並將其插入上表。

獲取我需要的信息的查詢如下：

select customerNumber, sum(quantityOrdered * priceEach) as orderTotal, curdate() as todaysDate 
from orders join orderdetails

where orders.orderNumber = orderdetails.orderNumber

group by orders.customerNumber

having orderTotal > 150000

我嘗試過使用：

insert into topCustomers( customerNumber, orderTotal, curdate())

在我的選擇查詢之前，這不是它應該如何工作。

任何指導都會很棒!!

先謝謝大家

在INSERT INTO語句的括號中，放置要插入的FIELD NAMES。 您沒有名為CURDATE()的字段名稱，因此查詢失敗。 代替：

insert into topCustomers( customerNumber, orderTotal, CustomerDate) 
select customerNumber, sum(quantityOrdered * priceEach) as orderTotal, curdate() as todaysDate 
from orders join orderdetails    
where orders.orderNumber = orderdetails.orderNumber    
group by orders.customerNumber    
having orderTotal > 150000

例：

mysql> create table test2 (cdate date);
Query OK, 0 rows affected (0.32 sec)

mysql> INSERT INTO test2 (curdate());
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual tcorresponds to your MySQL server version for the right syntax to use near 'cte())' at line 1

mysql> INSERT INTO test2 (cdate) SELECT curdate();
Query OK, 1 row affected (0.07 sec)
Records: 1  Duplicates: 0  Warnings: 0
