How to resolve errors when creating a partitioned table in Oracle?
When creating a partitioned table, various errors may arise. Here are some common errors and their solutions:
- ORA-14020: Error causing invalid partition key column.
This error is typically caused by the partition key column having an incompatible data type or incorrect length. Make sure the data type and length of the partition key column match the definition of the partition scheme. - ORA-14024: Error with specified partition range.
This error typically occurs due to incorrect definition of the partition range. Check the definition of the partition range to ensure that the values of the partition key column fall within the partition range. - ORA-14074: Error due to incompatible partition definition with existing table. This typically occurs when attempting to create a partition on an existing table where the structure is not compatible with the partition definition. In this case, the table data must be backed up, and a new partition table must be recreated.
- ORA-14400: Error inserting invalid partition key value
This error typically occurs when attempting to insert a value that does not comply with the partition key definition. Check the insert statement to ensure that the inserted value complies with the partition key definition. - ORA-14401: Invalid partition key error
This error typically occurs when attempting to update a partition key column with a value that does not conform to the partition key definition. Review the update statement to ensure that the updated value complies with the partition key definition.
Ways to resolve these errors include: checking if the data type and length are correct, ensuring that the partition range and keys are defined properly, backing up data and recreating partition tables, verifying that the values in insert and update statements comply with the partition key definition. If these methods do not solve the issue, you can consult the specific error message and Oracle documentation for further assistance.
