Question

This is my example of my table:

id | name | foreign_id |
-------------------------
1    a       100
2    b       100
3    c       100
4    d       101
5    a       102
6    b       102
7    c       102

I would like to get the distinct file with the latest foreign_id (bigger number but not necessarily biggest).
In this example, it would be row with id 4,5,6,7. Anyone has any idea? Thank you very much!

Answer 1

Could you try something like below :-

SELECT Id,Table1.Name,Table1.Fid FROM Table1 INNER JOIN 
(SELECT Name,Max(FId) AS FId FROM Table1 Group By Name)
Table2 ON Table1.FId=Table2.FId AND Table1.Name=table2.Name

This works in Sql Server atleast. Please check in MySQL. Sorry, I dont have MySQL to test this.
