Oracle Tips by Burleson

Oracle 10g ROWID option

After performing a typical LogMiner operation, a ROWID clause is included in the reconstructed sql_redo and sql_undo statements by default, and the statements are ended with a semicolon ready for execution.

However with the new no_rowid_in_stmt option for the start_logminr procedure, you can now filter out the ROWID clause from the reconstructed sql_redo and sql_undo statements.  For example:

EXEC DBMS_LOGMNR.START_LOGMNR( OPTIONS => DBMS_LOGMNR.NO_ROWID_IN_STMT);

How does this feature help? Rowid(s) are not consistent between databases (unless there is a physical standby). So if you intend to re-execute the sql_redo or sql_undo statements against a different database than the original one, this option becomes important. Instead of rowids, primary key constraints are used to identify the rows to manipulate.
