MySQL query to fetch multiple least values?
For this, you can use a sub query along with MIN(). Let us first create a table−
mysql> create table DemoTable -> ( -> Name varchar(20), -> Score int -> ); Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('John',56);
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('John',45);
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable values('John',58);
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values('Chris',43);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('Chris',38);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Chris',87);
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement−
mysql> select *from DemoTable;
This will produce the following output−
+-------+-------+ | Name | Score | +-------+-------+ | John | 56 | | John | 45 | | John | 58 | | Chris | 43 | | Chris | 38 | | Chris | 87 | +-------+-------+ 6 rows in set (0.00 sec)
Here is the query to fetch multiple least values−
mysql> select *from DemoTable tbl1 -> where Score IN( select min(Score) from DemoTable tbl2 where tbl1.Name=tbl2.Name);
This will produce the following output−
+-------+-------+ | Name | Score | +-------+-------+ | John | 45 | | Chris | 38 | +-------+-------+ 2 rows in set (0.00 sec)
