"ORA-14400: inserted partition key doesn't map to any partition"偶想了一个范围区间N就设置好了table
"ORA-14400: inserted partition key doesn't map to any partition" even thought a range interval N is set up on the table
我有一个版本为 19c (19.0.0.0.0) 的 Oracle 数据库。我收到错误“SQL 错误 [14400][72000]：ORA-14400：插入的分区键不映射到任何分区”，即使在 table 上设置了范围间隔 N .

有没有限制？
我已经看到 there are some logical limits on partitions number。但是在问题中上面提到的插入中，DB 在我指定的日期独立地只创建了一个额外的分区，所以这应该不是问题，我错了吗？也许还有其他我没有注意到的限制？
最大（子）分区数不适用于实际（子）分区数。该限制适用于基于现有最小值和最大值的理论数量，即考虑了差距。
正如我在推荐中提到的那样，您应该永远不要 将日期值存储为数字（或字符串），这是一个设计缺陷。始终使用正确的 DATE 或 TIMESTAMP 数据类型。
20210731 - 20190431 = 20'300 - 不是 823 天。您的每个分区都有 52 个子分区。 20'300 x 52 = 1'055'600 超过了 1024K 的限制 - 1 = 1'023'999 个子分区
除此之外20190431可能代表不存在的4月31日。
