Background: During the application development phase and more often the DDL needs to be backed up for the schema objects in .SQL format which supports the readability and recover or portability of the objects creation later on when needed. This could be easily done by the oracle data pump utility. Workaround: Step1: First make the…

Applications generates temporary data which may need less than minutes to days, these data need to be purged to claim spaces on database and housekeeping. One way to do this is to create a partitioned table and drops the older partitions based on a regular interval. The below example shows how to do this by…

Range partitioning is a great way to manage historical data in oracle database, data to be inserted in a partitioned table should have the specific partition exists beforehand otherwise the insert operation will fail. How to create partition automatically when the data added to the table? Interval partitioning is used to implement this feature which…
