插入任意值，並選擇在同一語句MYSQL

Question

我試圖做類似

INSERT INTO tbl_order_detail (key_order,key_product,fld_unit_price,fld_quantity) 
VALUES (<value1>, <value2>, 
SELECT fld_unit_price,fld_quantity FROM tbl_product WHERE key_product = <value2>); 

，這是什麼的正確語法？

Answer 1

INSERT INTO tbl_order_detail 
    (key_order,key_product,fld_unit_price,fld_quantity) 
SELECT <value1>, <value2>, fld_unit_price,fld_quantity 
FROM tbl_product 
WHERE key_product = <value2>; 

Answer 2

 INSERT 
INTO tbl_order_detail 
    (
    key_order, 
    key_product, 
    fld_unit_price, 
    fld_quantity 
) 
SELECT 
    <value1>, 
    <value2>, 
    fld_unit_price, 
    fld_quantity 
    FROM tbl_product 
    WHERE key_product = <value2> 
;
