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)
