How to use ON DUPLICATE KEY in insert statement

How to use ON DUPLICATE KEY in insert statement

Problem:
In case of inserting or updating record we use separate logic using if statement or case statement:
e.g.:

if(i==0)
insert here

if(i=1)
update here

we can terminate the above if statement by using On Duplicate Key.
by using this only one statement can be use for insert and update record.

*note: user_nm coulmn must be unique

Example:

INSERT INTO `posts` (`user_nm`, `no_of_update`, `inserted_on`, `update_on`)
VALUES ('a_user', 1, NOW(), NOW())
ON DUPLICATE KEY
UPDATE `no_of_update` = `no_of_update` + 1, `update_on` = NOW()

Mysql Database access using PDO

How to access Mysql Database using PDO:

PHP is changing day by day. in old days we were use mysql_connect(...) but now in current days it is not supported. current days we can use mysqli_connect(...). but it is better if we use PDO (PHP Data Object).

PHP Data Objects (PDO) is a very lightweight, consistent interface for accessing different types of databases in PHP. for this you simply tell the PDO database driver.

by using PDO you use the same functions to issue queries and fetch data in different types of database. PDO also remove all possibility of sql injections. for this it provide bind parameter facility.

Example:

Listed below full code that insert update delete list of all records. this code is in OOP based.


File: Db.php

<?php
class Db {
    private $pdo;
    private $stmt;

    function __construct() {
// set database setting here
