基于国家/地区的Mysql排除和包含
Posted
技术标签:
【中文标题】基于国家/地区的Mysql排除和包含【英文标题】：Mysql Exclude and Include based on countries 【发布时间】：2015-10-28 08:50:22 【问题描述】：我有一个逻辑问题需要解决。 我们有以下表格：
200 - 文章表（所有文章）
202 - 国家限制表（所有限制基于国家和文章）
如果文章在国家/地区限制表中没有结果，则该文章可以显示。
如果文章在国家限制表中有结果，但我们感兴趣的国家不存在，则该文章可以显示。
如果文章在国家限制表中有结果，并且我们感兴趣的国家存在且独占值为0，则文章可以显示。
如果文章在国家限制表中有结果，而其他国家有独占1，则该产品可以展示。
这是我的方法，但不是一个好方法...
SELECT `203`.ArtNr,
IF(
EXISTS((SELECT * FROM `202` WHERE `202`.ArtNr = `203`.ArtNr)),
'',
'yes'
) as 'Display' FROM `203`
WHERE `203`.RefNr_Search = 'GDB400'
AND `203`.ArtNr IN ('0 986 467 720','0 986 494 522','0 986 TB2 005','F 03A 150 016')
LKZ 值可以是：'RO','EU','OE'
这是这 4 篇文章的选择。上面的查询应该只返回两个结果（ArtNr=0 986 494 522，ArtNr=0 986 467 720）。我无法进行此查询...我们将不胜感激。

【问题讨论】：
使用这种命名标准非常困难。请参考以下链接：***.com/questions/5325520/…。表格内的数据也很烦人。 @AdarshGangadharan 这是一个文章查找表，我只想根据国家（LKZ）显示其中的两行:) 【参考方案1】：得到朋友的帮助，谢谢。
SELECT distinct (`203`.ArtNr) FROM `203`
LEFT JOIN `202` ON `202`.ArtNr = `203`.ArtNr
WHERE `203`.RefNr_Search = 'gdb400'
AND `203`.ArtNr IN ('0 986 467 720','0 986 494 522','0 986 TB2 005','F 03A 150 016')
AND (`202`.ArtNr IS NULL OR (`202`.Exclude = 0 AND `202`.LKZ IN('RO','EU','OE')) OR (`202`.Exclude = 1 AND `202`.LKZ NOT IN('RO','EU','OE')))
