MySQL Convert

                         

This section describes about the MySQL convert. It provides a way for converting the data of one type to another type.

Syntax: 

CONVERT(expr,type)

 

 

 

 

The "type" can have the following values:

  1. BINARY[(N)]
  2. CHAR[(N)]
  3. DATE
  4. DATETIME
  5. DECIMAL[(M[,D])]
  6. SIGNED [INTEGER]
  7. TIME
  8. UNSIGNED [INTEGER]

For example, BINARY converts a string to BINARY data type.

Table: employee

CREATE TABLE `employee` ( 
`emp_id` int(11) NOT NULL auto_increment, 
`emp_name` varchar(100) character set utf8 NOT NULL, 
`emp_salary` int(11) NOT NULL, 
`emp_startDate` datetime NOT NULL, 
`dep_name` varchar(50) NOT NULL, 
PRIMARY KEY (`emp_id`) 
)

Data in the above table: (Using SELECT * FROM employee;)

In the following query we will use MySQL convert() function. 

SELECT CONVERT(emp_id,CHAR) AS Character_Emp_Id, 
CONVERT(emp_startDate,Date) AS Character_emp_Salary 
FROM employee;

Output:
