Search case insensitive all duplicate records and print out


#1

Hi folks

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.

SELECT lower(leaf_user_name), COUNT (lower(leaf_user_name)) AS numoccurrences
FROM rss_user
WHERE rss_name = ‘sunone_west’
GROUP BY leaf_user_name
HAVING COUNT (lower(leaf_user_name)) > 1;

Is there a Toad way to do the same?

cheers Sven

The GROUP BY should also be (lower(leaf_user_name)). And I would use COUNT(*)
but that makes no difference as far as I know.

Did you try this query? I would expect errors because of the fact that the group
by does not match the first select expression.

Groetjes,
Wim

I run this query without error message in Toad. Thanks for help.

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;

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