Question

我在将一行插入表dbo.CFD时遇到错误。完整的错误说明：

无法在对象＆＃39; dbo.CFD＆＃39;中插入重复的关键行具有唯一索引＆＃39; IX_CFD_NRSC_FXTR_N＆＃39;。重复键值为（BP2001,1990，CHK，01,3 3456）。

查看相关索引IX_CFD_NRSC_FXTR_N，它是单个列上的非唯一非聚集索引（错误中包含BP2001的列）。

查看数据，有许多记录的BP2001，CHK，01和3456的值，但没有1990年（但各种其他值），所以它似乎并没有与一个独特的冲突约束

我还验证了所有外键约束都得到了满足，并且没有违反主键约束。

如何确定导致此问题的确切原因？我可以找到的每个例子都会导致插入重复数据，但我不认为这是问题所在。谢谢！
