连接两个表

Question

当单个表如何获得它们的范围内的记录，我用这个查询得到的范围内记录：

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

但连接两个表后，怎么能我得到范围内的记录。 在这里，我使用的外键下面，

customer.productId = productDetails.productId 

我的查询：

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
