Mysql 基于国家/地区排除和包含

Question

我有一个逻辑问题需要解决。我们有以下 tables:

200 - 文章table（所有文章）
202 - 国家限制table（所有限制基于国家和文章）

如果某篇文章在国家/地区限制table中没有结果，则该文章可以显示。

如果一篇文章在国家/地区限制table中有结果，但我们感兴趣的国家/地区不存在，那么文章可以显示。

如果该文章在国家限制table中有结果，并且我们感兴趣的国家存在并且独占值为0，则该文章可以显示。

如果文章在国家/地区限制table中有结果，并且其他国家/地区有独占1，那么该产品可以显示。

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 值可以是这些：'RO'、'EU'、'OE'

这是这 4 篇文章的选择。上面的查询应该 return 只有两个结果（ArtNr=0 986 494 522，ArtNr=0 986 467 720）。我无法进行此查询...将不胜感激。

有朋友帮忙，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')))
