我有一个庞大的公司对数据集与他们的资金风险资本家，我想检查这对货币对中只有一个是由VC资助的（如果是列OVC = 1，否则为0），两个合作伙伴都是由至少一个VC（如果是列BVB = 1）或两个合作伙伴是否由同一VC资助（如果是列CVC = 1）。目前，我的表中列有Partner11，其资金来自风险投资VC11至VC17，以及Partner22，其资金风险投资在VC21至VC27。为了能够在一行中说明标题，我在下表中省略了VC14-VC17和VC24-27。
Partner11 | VC11 | VC12 | VC13 | Partner22 | VC21 | VC22 | VC23 | OVB | BVB | CVC
FirmA | | | | FirmB | | | | 0 | 0 | 0
FirmC | Moa | | | FirmD | | | | 1 | 0 | 0
FirmE | Moa | Fred | Bob | FirmF | | | | 1 | 0 | 0
FirmG | | | | FirmH | Bob | Zoe | Jet | 1 | 0 | 0
FirmE | Moa | | | FirmF | Jet | | | 0 | 1 | 0
FirmG | Moa | Fred | Bob | FirmH | Jet | Zoe | | 0 | 1 | 0
FirmG | Moa | Fred | Bob | FirmH | Bob | Zoe | Jet | 0 | 0 | 1
FirmG | Jet | Bob | Fred | FirmH | Bob | Zoe | Jet | 0 | 0 | 1
如果没有合作伙伴获得风险投资支持，OVB，BVB和CVC的值为0（见第1行）。
要在OVB列中插入0或1，代码应检查该对中的一个伙伴在partner11的VC11-VC17列中是否至少有一个值，或者在伙伴22的VC21-VC27列中是否包含（不包括）见第2至4行。
要在BVB列中插入0或1，代码应检查两个伙伴是否至少在其VC列之一中具有值（对于VC11-VC17中的partner11，对于VC21-VC27中的partner22）（请参阅行） 5 + 6）。
要在CVC列中插入0或1，代码应该将伙伴的VC列的值相互比较，这意味着VC11应该与VC21，VC22，VC23，VC24，VC25，VC26和VC27进行比较; VC12与VC21，VC22，VC23，VC24，VC25，VC26，VC27等（见第7 + 8行）。
我真的很感激有任何帮助来解决这个问题。
非常感谢你。
答案 0 :(得分：0)
嗯，这是我写过的最糟糕的查询。但是，当你的桌子没有标准化时，这就是你最终的结果。如果这有助于我，请告诉我：
运行以下内容以更新OVB和BVB以及CVC（SQL Fiddle）：
