我们可以在mysql 5.7的创建表中使用select ... into命令吗？

Question

我在ubuntu 16.04 lts上使用mysql服务器5.7，我想创建一个使用其他表中值的表。我在创建表时尝试使用select ... into，但是失败了。我创建了如下表。

mysql> create table BILLING_PRODUCTS_DETAILS
    -> (
    -> bill_Number int not null,
    -> product_id int not null,
    -> unit_Price decimal(8,2) not null,
    -> purchase_Quantity int default 1,
    -> purchase_Quantity_Price decimal(10,2) not null,
    -> foreign key (bill_Number) references BILL_HEADER(bill_Number),
    -> foreign key (product_Id) references PRODUCT_DETAILS(product_Id),
    -> select product_Price into unit_Price from PRODUCTS_DETAILS where product_Id = PRODUCTS_DETAILS.product_Id,
    -> select (purchase_Quantity * unit_Price) into purchase_Quantity_Price
    -> );

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'select product_Price into unit_Price from PRODUCTS_DETAILS where product_Id = PR' at line 10

Answer 1

我认为您可以有一个更好的选择。您首先创建表，然后更新它。很简单。
