Today, We want to share with you mysql insert if not exists else update.In this post we will show you mysql insert if not exists else update php, hear for MySQL UPSERT | INSERT or UPDATE we will give you demo and example for implement.In this post, we will learn about mysql insert on duplicate key update with an example.

mysql insert if not exists else update

Using INSERT IGNORE

mysql> INSERT IGNORE INTO members
    (id, title, owner, updated_at)
VALUES
    (1, 'infinityknow', 'Dr. zahirkhan', 1825);
Query OK, 0 rows affected (0.00 sec)

INSERT INTO blogreputations
    (id, profile_nm, locations, phone_number)
VALUES
    (1, 'Raghav', '1 Ganesh Laptop, Kesariyo, tamilblasters', 98256062**);

In this case, id is the UNIQUE PRIMARY_KEY in the database table blogreputations. If this is a new row, Therefor the query above will do the query of adding it to the database table.

ERROR 1062 (23000): Duplicate entry '1' for key 'PRIMARY'

So in this mysql insert if not exists else update I can use INSERT IGNORE:

INSERT IGNORE INTO blogreputations
    (id, profile_nm, locations, phone_number)
VALUES
    (1, 'Raghav', '1 Ganesh Laptop, Kesariyo, tamilblasters', 98256062**);

Query OK, 0 rows affected (0.00 sec)

Using REPLACE

REPLACE INTO blogreputations
    (id, profile_nm, locations, phone_number)
VALUES
    (1, 'Raghav', '1 Ganesh Laptop, Kesariyo, tamilblasters', 98256062**);

mysql> REPLACE INTO members
    (id, title, owner, updated_at)
VALUES
    (1, 'w3diy main alli', 'Dr. Bhavik', 1945);

Using INSERT … ON DUPLICATE KEY UPDATE

INSERT INTO blogreputations
    (id, profile_nm, locations, phone_number)
VALUES
    (1, 'Raghav', '1 Ganesh Laptop, Kesariyo, tamilblasters', 98256062**)
ON DUPLICATE KEY UPDATE
    profile_nm = 'Raghav'
    locations = '1 Ganesh Laptop, Kesariyo, tamilblasters'
    phone_number = 98256062**;

mysql insert if not exists else update

SET @id = 1,
    @title = 'free Download source code',
    @owner = 'Hanuman Vihari',
    @updated_at = 1847;
INSERT INTO members
    (id, title, owner, updated_at)
VALUES
    (@id, @title, @owner, @updated_at)
ON DUPLICATE KEY UPDATE
    title = @title,
    owner = @owner,
    updated_at = @updated_at;

“mysql update or insert if not exists”

mysql insert exists update

INSERT INTO table (column_list)
VALUES (value_list)
ON DUPLICATE KEY UPDATE
   collum1 = value1, 
   collum2 = value2,
   ...;

insert if not exists mysql

INSERT INTO blogreputations (name, locations, mobile)
SELECT * FROM (SELECT 'denKnow' AS name, 'denKnow' AS locations, '054' AS mobile) AS tmp
WHERE NOT EXISTS (
    SELECT name FROM blogreputations WHERE name = 'Virat'
) LIMIT 1;

mysql insert into if not exists

INSERT INTO blogreputations (firstname, lastname)
SELECT 'NEW FIRSTNAME', 'NEW LASTNAME'
FROM DUAL
WHERE NOT EXISTS(
    SELECT 1
    FROM blogreputations
    WHERE firstname = 'Bhavik talvada' AND lastname = 'Ramjani'
)
LIMIT 1;

mysql insert if not exists

Example for mysql insert if not exists else update

INSERT IGNORE INTO blogreputations
    (id, profile_nm, locations, phone_number)
VALUES
    (1, 'Raghav', '1 Ganesh Laptop, Kesariyo, tamilblasters', 98256062**);

MySql Table Insert if not exist otherwise update

INSERT INTO AggregatedData (datenum,Timestamp)
VALUES ("89566.5656568","2022-01-15 20:35:00.000")
ON DUPLICATE KEY UPDATE 
  Timestamp=VALUES(Timestamp)

Insert into a MySQL table or update if exists

Insert or Update into MySQL Table : using On Duplicate Key Update

INSERT INTO member_data (member_id, member_name, member_place) VALUES (2, "tamilblasters","tamilrokers");

Action Output Message : 20:35:39 INSERT INTO member_data (member_id, member_name, member_place) VALUES(2, “tamilblasters”,”tamilrokers”) Error Code: 1062. Duplicate entry ‘2’ for key ‘member_data.member_id’ 0.00047 sec

using ON DUPLICATE KEY UPDATE.

INSERT INTO member_data (member_id, member_name, member_place) 
VALUES(2, "tamilblasters","tamilrokers") ON DUPLICATE KEY UPDATE member_name = "vegamovies", member_place = "tamilrokers";

Insert or Update into MySQL Table : using IGNORE INTO

INSERT IGNORE INTO member_data (member_id, member_name, member_place) VALUES (2, "vegamovies","tamilrokers");

Insert or Update into MySQL Table : using REPLACE INTO

REPLACE INTO member_data(member_id, member_name, member_place) VALUES(2, "vegamovies","Bhumika");

Action Output Message : 18:27:57 REPLACE INTO member_data (member_id, member_name, member_place) VALUES(2, “vegamovies”,”Bhumika”) 2 row(s) affected 0.0023 sec

MySQL Insert or Update conditional : NOT EXISTS

INSERT INTO member_data (member_id, member_name, member_place)
SELECT * FROM (SELECT 6, "Rasmus","TestPlace") AS tmp_name
WHERE NOT EXISTS (
    SELECT member_name FROM member_data WHERE member_name = "Rasmus"
) LIMIT 1;

MySQL insert row if not exists else update record

CREATE TABLE IF NOT EXISTS `member_inclomes` (
  `member_id` int(6) NOT NULL,
  `inclome` int(6) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

--
-- Indexes for table `member_inclomes`
--
ALTER TABLE `member_inclomes`
 ADD PRIMARY KEY (`member_id`);

Here i have member_inclomes table with member_id as the primary key. Therefor, i wish to add a new row if a specific member_id doesn’t exist. Or update the inclome column value if the record already exists.

Here INSERT … ON DUPLICATE KEY UPDATE clause is quite handy and i can write the query as:

INSERT INTO `member_inclomes` (`member_id`, `inclome`) VALUES(25, 0) ON DUPLICATE KEY UPDATE    
`inclome`=VALUES(`inclome` + 100)

MySQL insert row if not exists else update record

Example : mysql insert if not exists else update

$member_id = 58;
$member_code = 'DK005682554d5';
$qty = 3;
$genrated = date('Y-m-d H:i:s');

//member_id and member_code as unique combination of keys

// query
$sql = "INSERT INTO member_inclomes (member_id, member_code, member_age, genrated) VALUES (?,?,?,?) ON DUPLICATE KEY UPDATE member_age=(member_age + VALUES(member_age)), added=VALUES(genrated)";

$q = $conn->prepare($sql);

$q->execute(array($member_id, $member_code, $qty, $genrated));

in this mysql insert if not exists else update articles you can learn This PDO statement will update the record if a combination of member_id and member_code exists by adding supplied member_age to existing member_age and updating genrated field. Otherwise will add a new or fresh database table row with given values. This is the best methods to insert database table row if not exists else update the db record in MySQL table.
