How To Get Rowid From Table In Oracle

You should not use ROWID as a table's primary key. If you delete and reinsert a row with the Import and Export utilities, for example, its rowid may change. If you delete a row, Oracle may reassign its rowid to a new row inserted later.

  • Because a new column might be inserted with a ROWID lower than an already existing old one. You can assume that the chances of a new row getting a higher rowid than the old ones in the table are somewhat higher than getting a lower one (especially when there have NEVER been any deletions from the table) but you can NOT depend on it.
