Question

DELETE FROM LIM_STAGE.RESULTS A 
WHERE ROWID > ( SELECT min(1) 
                FROM LIM_STAGE.RESULTS B
                WHERE A.result_number = B.result_number );

This code returns error
Error
ORA-00932: inconsistent datatypes: expected ROWID got NUMBER

And I am not sure how to alter it to get the results needed.

It seems where I have the numeral 1 should be something else, but I cannot figure out how to actually establish the individual row numbers.

Appreciate help getting rid of these duplicate rows. This is a large table with many indexes, and triggers… hate to hae to rewrite everything.

Thank you for any help..

This should work:

delete from lim_stage.results
where rowid not in (
    select min(rowid)
    from lim_stage.results
    group by result_number
)
