Get row with highest or lowest value from a GROUP BY

Question

I\'m trying to get the row with the highest/lowest number, after performing a GROUP BY:

Here is my test data

mysql> SELECT * FROM tes         


        

Answer 1

I think this is what you are trying to achieve:

SELECT t.* FROM test t
JOIN 
( SELECT Name, MIN(Value) minVal
  FROM test GROUP BY Name
) t2
ON t.Value = t2.minVal AND t.Name = t2.Name;

Output:

ID	VALUE	NAME
1	10	row1
4	5	row2

See this SQLFiddle

• Demo with more values
• Demo with duplicate values
• Demo with removing duplicate values (using DISTINCT)

Here I have self-joined the table with minVal and Name.
