edit

When there is an issue in generating a sequence object within an Oracle database, it means that the system is unable to create a unique sequence number for a specific table or column. This can cause errors in inserting or updating data, as well as inconsistencies in data retrieval. Possible causes of this issue include incorrect permissions or syntax errors in the sequence definition, system resource constraints, or database corruption. It is important to address this issue promptly to ensure data integrity and prevent further database problems.
