Question

我可以在mykey（主键）存在时更新我的表，或者当mykey不存在时插入，使用此查询：

INSERT INTO customers (id, customer_id, page_id, mykey, hits) 
 VALUES 
(NULL, 1, 1, 23, 49) ON DUPLICATE KEY UPDATE hits=hits+49;

工作正常。现在我无法弄清楚如何在一个查询中添加多个值。我想要的是这个：

INSERT INTO customers (id, customer_id, page_id, mykey, hits) 
 VALUES 
(NULL, 1, 1, 23, 49) ON DUPLICATE KEY UPDATE hits=hits+49,
(NULL, 2, 2, 56, 11) ON DUPLICATE KEY UPDATE hits=hits+11,
(NULL, 3, 3, 81, 14) ON DUPLICATE KEY UPDATE hits=hits+14;

但这不起作用。是否可以在一个查询中插入或更新这样的多个值？

Answer 1

INSERT INTO customers (id, customer_id, page_id, mykey, hits) 
 VALUES 
(NULL, 1, 1, 23, 49),
(NULL, 2, 2, 56, 11),
(NULL, 3, 3, 81, 14)
ON DUPLICATE KEY UPDATE hits=hits+VALUES(hits);

Answer 2

在结束时执行ON DUPLICATE KEY UPDATE：

INSERT INTO customers (id, customer_id, page_id, mykey, hits) 
 VALUES 
(NULL, 1, 1, 23, 49),
(NULL, 2, 2, 56, 11),
(NULL, 3, 3, 81, 14) 
ON DUPLICATE KEY UPDATE hits=hits+VALUES(hits);

使用重复键和不同更新插入多个值
