Question

对于单个表，我使用此查询获取范围内的记录：

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

但是在加入两个表之后，我怎样才能得到范围内的记录。在这里，我使用如下的外键，

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

如何在连接两个表时获取范围内的记录
