This topic provides information on managing the recycle bin.
Background information
The recycle bin temporarily stores deleted database objects. ODC allows you to search for and recover the deleted database objects.
Technically, the recycle bin is a data dictionary table that stores the information about deleted database objects. Deletion here refers to the DROP operation. Data that is deleted by the DELETE operation will not be moved to the recycle bin. Therefore, an object deleted by the DROP operation is not permanently deleted and still occupies storage space. You can use the PURGE operation or empty the recycle bin in ODC to release the space.

Parameter Description Original Name The name of the deleted object specified by its creator. You can click Original Name to sort the objects by original name in ascending or descending order. Object Name The name that ODC gives to the object. Unlike the original name, the object name is never repeated and can uniquely identify an object. Object Type The type of the deleted object.
