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
