Implement and set DOUBLE length in MySQL

To implement DOUBLE in MySQL, the syntax is as follows −

create table yourTableName
     (
     yourColumnName double(5,2) unsigned
);

Let us first create a table −

mysql> create table DemoTable1814
     (
     Amount double(5,2) unsigned
     );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1814 values(1.98);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1814 values(100.24);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1814 values(198.50);
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1814;

This will produce the following output −

+--------+
| Amount |
+--------+
|   1.98 |
| 100.24 |
| 198.50 |
+--------+
3 rows in set (0.00 sec)
