How to insert DECIMAL into MySQL database?

To insert decimal into MySQL, you can use DECIMAL() function from MySQL. The syntax is as follows

yourColumnName DECIMAL(TotalDigit,DigitAfterDecimalPoint);

To understand the above syntax, let us create a table. The query to create a table is as follows

mysql> create table DecimalInsert
   -> (
   -> Id int,
   -> Name varchar(100),
   -> Amount DECIMAL(4,2)
   -> );
Query OK, 0 rows affected (0.65 sec)

Insert the decimal value using insert command. The query is as follows

mysql> insert into DecimalInsert values(1,'John',12.4);
Query OK, 1 row affected (0.15 sec)

mysql> insert into DecimalInsert values(2,'Carol',12.34);
Query OK, 1 row affected (0.16 sec)

mysql> insert into DecimalInsert values(3,'Mike',1.424);
Query OK, 1 row affected, 1 warning (0.17 sec)

Display all records from the table using select statement. The query is as follows

mysql> select *from DecimalInsert;

The following is the output

+------+-------+--------+
| Id   | Name  | Amount |
+------+-------+--------+
|    1 | John  |  12.40 |
|    2 | Carol |  12.34 |
|    3 | Mike  |   1.42 |
+------+-------+--------+
