PHP MySQL Delete Data

Syntax

DELETE [ LOW_PRIORITY ] [ QUICK ] [ IGNORE ] FROM table
[WHERE conditions]
[ORDER BY expression [ ASC | DESC ]]
[LIMIT number_rows];

Example (MySQLi Object-oriented)

<?php
$hosting_name = "localhost";
$username = "main_user_version";
$password = "password";
$dbname = "pakainfo";

// Create connection
$db_connect = new mysqli($hosting_name, $username, $password, $dbname);
// Check connection
if ($db_connect->connect_error) {
  die("Connection failed: " . $db_connect->connect_error);
}

// sql to delete a record
$query_s = "DELETE FROM players WHERE id=3";

if ($db_connect->query($query_s) === TRUE) {
  echo "Record deleted successfully";
} else {
  echo "Error deleting record: " . $db_connect->error;
}

$db_connect->close();
?>

Example (MySQLi Procedural)

<?php
$hosting_name = "localhost";
$username = "main_user_version";
$password = "password";
$dbname = "myDB";

// Create connection
$db_connect = mysqli_connect($hosting_name, $username, $password, $dbname);
// Check connection
if (!$db_connect) {
  die("Sorry Connection failed: " . mysqli_connect_error());
}

// sql to delete a record
$query_s = "DELETE FROM players WHERE id=3";

if (mysqli_query($db_connect, $query_s)) {
  echo "Record deleted successfully";
} else {
  echo "Error deleting record: " . mysqli_error($db_connect);
}

mysqli_close($db_connect);
?>

Example (PDO)

<?php
$hosting_name = "localhost";
$username = "main_user_version";
$password = "password";
$dbname = "myDBPDO";

try {
  $db_connect = new PDO("mysql:host=$hosting_name;dbname=$dbname", $username, $password);
  // set the PDO error mode to exception
  $db_connect->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

  // sql to delete a record
  $query_s = "DELETE FROM players WHERE id=3";

  // use exec() because no results are returned
  $db_connect->exec($query_s);
  echo "Record deleted successfully";
} catch(PDOException $e) {
  echo $query_s . "<br>" . $e->getMessage();
}

$db_connect = null;
?>

Example – With One condition

DELETE FROM players
WHERE player_name = 'ViratKohali';

SELECT count(*)
FROM players
WHERE player_name = 'ViratKohali';

Example – With Two conditions

DELETE FROM players
WHERE player_name = 'ViratKohali'
AND player_id < 1000;

SELECT count(*)
FROM players
WHERE player_name = 'ViratKohali'
AND player_id < 1000;

Example – With LIMIT modifier

DELETE FROM players
WHERE player_name = 'ViratKohali'
ORDER BY player_id DESC
LIMIT 1;

DELETE FROM players
WHERE player_name = 'ViratKohali'
ORDER BY player_id ASC
LIMIT 1;

DELETE FROM players
ORDER BY player_id DESC
LIMIT 1;

Example – Using EXISTS Condition

DELETE FROM teams
WHERE EXISTS
  ( SELECT *
    FROM players
    WHERE players.player_id = teams.team_id
    AND player_id > 500 );

SELECT COUNT(*) FROM teams
WHERE EXISTS
  ( SELECT *
    FROM players
    WHERE players.player_id = teams.team_id
    AND player_id > 500 );
