How can I only get the data with the same ID, but not the same Name?
The following is the example to explain my thought. Thanks.
ID Name Date
123 Amy 08/03/2022
123 Amy 12/03/2022
456 Billy 08/03/2022
456 Cat 09/03/2022
789 Peter 10/03/2022
Expected Output:
ID Name Date
456 Billy 08/03/2022
456 Cat 09/03/2022
How I have done.
select ID, Name, count(*)
from table
groupby ID, Name
having count(*) > 1
But the result included the following parts that I do not want it.
ID Name Date
123 Amy 08/03/2022
123 Amy 12/03/2022
One approach would be to use a subquery to identify IDs that have multiple names.
SELECT *
FROM YourTable
WHERE ID IN (SELECT ID FROM YourTable GROUP BY ID HAVING COUNT(DISTINCT Name) > 1)
