Question

I am currently using a version of:

SELECT a,b
FROM tbl
GROUP BY a,b
HAVING COUNT(*)>1;

I know the results are correct given what actions I’ve taken on the table. But, it doesn’t actually show me the duplicates. The “GROUP BY” clause blocks the other half of the records from showing.

I know this probably has a simple solution, but how do I actually show the duplicates? In other words, if there are 110 duplicates, I should get 220 records.

Thanks

Answer 1

I apologize. Since I knew the limits for field b, I was really using the wrong kind of statement. I ended up going with:

SELECT * FROM tbl
    WHERE (b = x OR b = y)
    AND a IN (SELECT a FROM tbl WHERE b = y)
    ORDER BY a ASC

This gave me exactly what I needed.

Thanks for all the input.
