When I was delete record Users, the ID primary key auto increment always jumping, I want ID auto increment is sequence again, this sample
| ID | UserName |
| 1 | Budi |
| 2 | Joko |
| 3 | Amir |
when I delete users Joko, then I add new other user, the ID number is jumping
| ID | UserName |
| 1 | Budi |
| 3 | Amir |
| 4 | Faris |
I have some solution in stackoverflow, but does’t work,
here I have add modified file
config/app.php
'SQLkonek' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'username' => 'root',
'paassword' => ' ',
'database' => 'klinikucing',
'encoding' => 'utf8mb4',
'timezone' => ' ',
'cacheMetadata' => true
]
then I call modified above through
controller/UsersController.php
public function delete ($id = null)
{
$this->request->allowMethod(['post', 'delete']);
$kon = ConnectionManager::get('SQLkonek');
$user = $this->Users->get($id);
$stm = $kon->execute(array(
['SET @count = 0'],
['DELETE FROM users WHERE ID = :ID'],
['UPDATE users SET users.ID = @count:= @count + 1'],
['ALTER TABLE users AUTO_INCREMENT =1']
))
->fetchAll('assoc');
If($this->Users->$stm) {
$this->Flash->success(__('Users success delete.'));
} else {
$this->Flash->error(__('User delete failed, try again.'));
}
return $this->redirect(['action' => 'index']);
The error message was shown
