Display 3 decimal places in MySQL?

To display 3 digits after decimal, use TRUNCATE(). Let us first create a table −

mysql> create table DemoTable
(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   Value DECIMAL(10,5)
);
Query OK, 0 rows affected (0.51 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(Value) values(109.4567);
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable(Value) values(15.9875);
Query OK, 1 row affected (0.28 sec)
mysql> insert into DemoTable(Value) values(1234.2346789);
Query OK, 1 row affected, 1 warning (0.14 sec)

Following is the query to display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----+------------+
| Id | Value      |
+----+------------+
| 1  | 109.45670  |
| 2  | 15.98750   |
| 3  | 1234.23468 |
+----+------------+
3 rows in set (0.00 sec)

Here is the query to display 3 digits after decimal i.e. 3 decimal places −

mysql> select truncate(Value,3) from DemoTable;

This will produce the following output −

+-------------------+
| truncate(Value,3) |
+-------------------+
| 109.456           |
| 15.987            |
| 1234.234          |
+-------------------+
3 rows in set (0.00 sec)
