How to use MySQL decimal?

MySQL decimal data type can be used to store the exact numerical value. The syntax of DECIMAL data type.

yourColumnName Decimal(integerValue,intgerValue);

Example of DECIMAL data type.

   -> (
   -> EmpId int auto_increment primary key,
   -> EmpName varchar(200),
   -> EmpSalary DECIMAL(6.2)
   -> );

Whenever we insert a value in “EmpSalary” column greater than 6 digits, it raise an error. The error is as follows −

mysql> insert into EmployeeInformation(EmpName,EmpSalary) values('John',6999999.50);
