連接兩個表

Question

當單個表如何獲得它們的範圍內的記錄，我用這個查詢得到的範圍內記錄：

SELECT customerId,firstName,lastName FROM customer WHERE customerId BETWEEN min AND max; 

但連接兩個表後，怎麼能我得到範圍內的記錄。 在這裏，我使用的外鍵下面，

customer.productId = productDetails.productId 

我的查詢：

SELECT customer.custId, customer.productId,GROUP_CONCAT(productDetails.productName) as productName, GROUP_CONCAT(productDetails.productPrice) as productPrice FROM customer, productDetails WHERE customer.productId = productDetails.productId GROUP BY productDetails.productId 

Answer 1

from what I understand you just need to add an "AND" condition to the query 


WHERE customer.productId = productDetails.productId 
AND customer.custId BETWEEN min and max; 
GROUP BY productDetails.productId
