Oracle : 11GR2 - IGNORE_ROW_ON_DUPKEY_INDEX Hint

Silently ignore new rows that violate a single unique index.  The IGNORE_ROW_ON_DUPKEY_INDEX hint applies only to single-table INSERT operations. It is not supported for UPDATE, DELETE, MERGE, or multitable insert operations. IGNORE_ROW_ON_DUPKEY_INDEX causes the statement to ignore a unique key violation for a specified set of columns or for a SINGLE specified index. When a unique key violation is encountered, a row-level rollback occurs and execution resumes with the next input row. As with all hints, a syntax error in the hint causes it to be silently ignored. The result will be that ORA-00001 will be caused, just as if no hint were used. Ref Bulk operations? Multiple rows with same UK being inserted - which get in - arbitrary ?
