查询语句
$Sql_hkpdf = "SELECT * , group_concat(' ' , concat_ws( ' X ', `jj_sku` , `quantity_purchased` ) , if(`quantity_purchased`> 1, '****' , ' ') ),group_concat(' ' , `order_id` , ' ') FROM ( select * from `sale_orders_restock` order by `jj_sku`) T WHERE `number` =$id AND 1=(select count(*) from `sale_orders_restock` where `recipient_name`=T.`recipient_name`) AND `quantity_purchased`=1 AND `delivery_areas` = 'HKS' GROUP BY `recipient_name` , `ship_address_1` ORDER BY length(group_concat( ' ' , concat_ws( ' X ', `jj_sku` , `quantity_purchased` ) , ' ' )) DESC,`jj_sku`"; $Result = mysql_query($Sql_hkpdf); 第一次写入数据之后，查询没问题，能查询到相关数据，一但第二次写入重复的数据，同样的查询语句就查询不出结果，都是空值，请问题这是什么原因呢？
回复讨论(解决方案)
1=(select count(*) from `sale_orders_restock` where `recipient_name`=T.`recipient_name`
你能保证 recipient_name 唯一吗？
recipient_name这个不是唯一的，这里面没有唯一的字段，我后面加了个ID字段
我就是需要经常导入重复的数据，才这样的
既然不唯一，那么 1=(select count(*) from `sale_orders_restock` where `recipient_name`=T.`recipient_name`) 在什么时候能成立呢？
当然只在 recipient_name 的值只有一个的时候，否则不就是 2、3、4...了吗
`number` =$id AND 1=(select count(*) from `sale_orders_restock`
这里有个number,类似于批号，每次导入的都是不一样的，第一次导入number=1,第二次就会＝2,在每批次的情况进下进行汇总的
number 不会作用到 select count(*) from 里面
xuzuning大大，那要怎么写啊
1=(select count(*) from `sale_orders_restock` where `recipient_name`=T.`recipient_name` and 'number'=$id) 这样？？
select count(*) from `sale_orders_restock` where `recipient_name`=T.`recipient_name` and 'number'=$id
的含义是：统计表 sale_orders_restock 中满足 recipient_name`=T.`recipient_name` and 'number'=$id 这个条件的记录数
当重复插入后，记录数就可能大于 1
那么 1=(select ... 就不会成立了
大于1，语句够长，索引要好，不然数据量大了，可能会有慢查询
请问xuzuning大大，我应该怎么改语句才能满足我的需要呢？？
问题解决了，xuzuning大大帮我看看，这样应该就可以了吧
SELECT * , group_concat(' ' , concat_ws( ' X ', `jj_sku` , `quantity_purchased` ) , if(`quantity_purchased`> 1, '****' , ' ') ),group_concat(' ' , `order_id` , ' ') FROM ( select * from `sale_orders` where `number` =$id order by `sku`) T WHERE `number` =$id AND 1=(select count(*) from `sale_orders` where `number` =$id and `recipient_name`=T.`recipient_name`) AND `quantity_purchased`=1 AND `delivery_areas` = 'JPS' GROUP BY `recipient_name` , `ship_address_1` ORDER BY length(group_concat( ' ' , concat_ws( ' X ', `jj_sku` , `quantity_purchased` ) , ' ' )) DESC,`jj_sku`
