Re: search case insensitive all duplicate records and print out


#1

Hi Norman,

It is correct, but the GROUP BY is not. That one didn’t have the lower(). So
no doubles found because of problems with lower and uppercase.

Hi Sven,

Is this SQL correct? I wish to print out all duplicate records (case
insensitive). I have zero output and not sure if no duplicates or
wrong SQL statement.

It is correct.

SELECT lower(leaf_user_name), COUNT
(lower(leaf_user_name)) AS numoccurrences
FROM rss_user
WHERE rss_name = ‘sunone_west’

Are you really only checking this one name though?

GROUP BY leaf_user_name
HAVING COUNT (lower(leaf_user_name)) > 1;

>> Is there a Toad way to do the same?

Scheme Browser, Tables.
Select the table(s) - possibly one by one.
Right click.
Select Data Duplicates.
Work through the screens that appear.

Cheers,
