Hi Nagendra ,

It would be really helpful if you can tell us details about what you've tried so far and the problem you're facing.


Thanks,

Hi Nagendra,

As per what i have understood,

Let x be the column you wanted to find duplicates on,

use group by clause on x then followed by having clause using the count function

For example: Select x from sometable group by x having count(x) > 1
