How to Deduplicate Oracle ROWIDs

To deduplicate ROWID in Oracle, you can convert ROWID to a string using the ROWIDTOCHAR function, and then use the DISTINCT keyword for deduplication.

For example, let’s say there is a table called “table_name” with a column named “rowid_column” containing ROWIDs. To remove duplicates, you can use the following SQL statement:

Retrieve unique values converted from ROWIDs in the specified column of the table.

This will return a list of unique ROWIDs.
