ORA-14201: specified subpartition bound is too long ORACLE 报错 故障修复 远程处理

文档解释

ORA-14201: specified subpartition bound is too long

Cause: Length of a linear key representation of a high bound of a table subpartition being added or along which an existing table or index subpartition is being split exceeded the legal limit (4K).

Action: Change the representation of a subpartition high bound to bring its length within legal limit.

ORA-14201 指定的子分区界限过长是由于分区类型的子分区的大小或长度超出分区表的最大允许长度所引起的。

官方解释

ORA-14201: specified subpartition bound is too longCause: An attempt was made to add a subpartition to a partitioned table, a partition of a partitioned table, or a subpartition of a subpartitioned table, with a subpartition bound too long for the underlying partitioning type.Action: For composite partitioned tables, ensure that the bound value is shorter than or equal to the composite partitioning type’s maximum value length. For example, if the partitioning type is RANGE, then ensure that the subpartition bound is shorter than or equal to the maximum size of the partitioning type, which is 64K.

常见案例

ORA-14201 错误的一个常见案例是在尝试使用一个超过其分区表允许的范围或长度的子分区界限时出现。假设你有一个最多容纳64K字节子分区值的分区表，但是你尝试插入一个超过64K字节的值，那么将会抛出ORA-14201错误。

正常处理方法及步骤

要解决ORA-14201错误，您需要确保插入到子分区界限中的值没有超过其基本分区类型的最大长度/范围。通常，错误消息中会列出允许的子分区界限长度/大小。但是，如果您不知道基本分区类型的最大值，可以使用以下查询来获取指定分区类型的最大值：

SELECT HIGH_VALUE

FROM DBA_PART_KEY_COLUMNS

WHERE SUBPARTITION_POS = 0

AND PARTITIONING_TYPE = ;
