How to find the minimum values of two or more fields in MySQL?
To find the minimum values of two or more fields, use LEAST() function from MySQL −
select least(yourColumnName1,yourColumnName2,...N) from yourTableName;
Let us first create a table −
mysql> create table DemoTable
-> (
-> Date1 date,
-> Date2 date,
-> Date3 date
-> );
Query OK, 0 rows affected (0.54 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('2019-03-31','2019-01-01','2019-03-05');
Query OK, 1 row affected (0.17 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+------------+------------+------------+
| Date1 | Date2 | Date3 |
+------------+------------+------------+
| 2019-03-31 | 2019-01-01 | 2019-03-05 |
+------------+------------+------------+
1 row in set (0.00 sec)
Following is the query to retrieve the minimum value in MySQL −
mysql> select least(Date1,Date2,Date3) from DemoTable;
