Hi Renish,
If you want to capture the entries which are entered more than once.
Here's the answer for it.
mysql> select * from a;
+--------+
| b |
+--------+
| pen |
| pencil |
| rubber |
| pen |
| paper |
| paper |
+--------+
6 rows in set (0.00 sec)
mysql> select b from a group by b having count(b)>1;
+-------+
| b |
+-------+
| paper |
| pen |
+-------+
2 rows in set (0.00 sec)
Hope this helps.
Thanks,
ViSolve DB Team.
Or (IIRC):
SELECT col_with_dupes, COUNT(col_with_dupes)
FROM table
GROUP BY col_with_dupes
HAVING COUNT(col_with_dupes) > 1
