I have read several threads about this but still not exactly my problem.
So in the users table I have a column called role, which is enum type and has two available values: 1 and 2. I set 2 as the default one. Now I want to change it to 1, for example. I created a new migration, ran php artisan migrate and encounter this error:
[Illuminate\DatabaseQueryException]
SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'role' (SQL: alter table `u
sers` add `role` enum('1', '2') not null default '1')
[PDOException]
SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'role'
Here is code in my CreateUsersTable migration file:
$table->enum('role', ['1', '2'])->default('2');
And I did the same in the new UpdateUsersTable migration file:
$table->enum('role', ['1', '2'])->default('1');
And by the way I can not use php artisan migrate:refresh because it will delete all my data. Where am I doing wrong?
$table->enum('role', ['1', '2'])->default('1')->change();
<?php
use Illuminate\Support\Facades\DB;
use Illuminate\Database\Migrations\Migration;
class UpdateUsersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
DB::statement('ALTER TABLE `users` MODIFY `role` DEFAULT 1;');
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
DB::statement('ALTER TABLE `users` MODIFY `role` DEFAULT 2;');
}
}
Adapted from this answer to another question
In order to do this you have to add ->nullable() or ->default() to every field you add to the migration file.
create a new migration file
php artisan make:migration add_role_to_users_table --table=users
open the created migration file (database\migrations\2021_12_01_050851-add_role_tables.php) and add below code.
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class AddRoleToUsers extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::table('users', function (Blueprint $table) {
$table->enum('role', ['1', '2'])->default('1')->comment('1 - admin, 2 - normal'); //added
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::table('users', function (Blueprint $table) {
$table->dropColumn('role'); //added
});
}
}
?>
Now migration refresh
php artisan migrate:refresh --path=/database/migrations/2021_12_01_050851-add_role_tables.php

Can anyone know how to create Table in laravel without created_at and Updated_at Column in table using a migration.
I try this Following code but it's still create created_at and Updated_at column in table:-
Migration Laravel :-
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateNewusersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('newusers', function (Blueprint $table) {
$table->bigIncrements('id');
$table->text('name');
$table->string('email', 100)->unique();
$table->bigInteger('phone_no');
});
}
/**

Add this in your model
public $timestamps = false;
I created two tables in database. But now I get error to create another one. Third table can not add in the database. But migrate successfully.
I tried all those thinks which are mentioned below:
php artisan make:migration create_book_table
php artisan migrate
after that I get an error:
SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes (SQL: alter table `Admins` add unique `admins_emai
l_unique`(`email`))
Then I tried:
php artisan migrate:refresh
but it's still not fixed.
Here is the migration file
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateBookTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('books', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email');
$table->string('phone-number');
$table->string('checkIn');
$table->string('checkOut');
$table->string('Room');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('books');
}
}
Put this line of code in your AppServiceProvider.php file in the boot function:
use Illuminate\Support\Facades\Schema;
public function boot()
{
Schema::defaultStringLength(191);
}
I want to create a new table, users_profile
here is the migration code
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersProfileTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('users_profile', function (Blueprint $table) {
$table->increments('id');
$table->string('city');
$table->string('country');
$table->integer('users_id')->unsigned();
$table->foreign('users_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('users_profile');
}
}
facing an error

use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration

public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('first_name');
$table->string('last_name');
$table->string('email')->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}
Although i am creating a new migration, a new table only i am declaring a primary key of users table as foreign key in users_profiles but facing the above error
help please!
Just a word of advice, Use Laravel Nomenclature to avoid these kind of issues. Always define your table names as plural snakecase and use singular camelcase model to access them.
In your case, change your table name to: user_profiles and use UserProfile model to access it automatically.
Ofocurse you need to change your class name in your migration accordingly: CreateUserProfilesTable
I believe it should resolve your issue.
I believe you are using : php artisan migrate and as users table already exists , running migration for users table again gives that error.
Use: composer dump-autoload and then php artisan migrate:refresh
to rollback all of your migrations and reinstall migrations.
Simple go to your database and drop Schema table ("users") and also remove entry in Schema table ("migrations") and run your migrations again...your problem is solve....
Is there any way/laravel-command to drop a specific table from the production server?
Set up a migration.
Run this command to set up a migration:
php artisan make:migration drop_my_table
Then you can structure your migration like this:
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class DropMyTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
// drop the table
Schema::dropIfExists('my_table');
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
// create the table
Schema::create('my_table', function (Blueprint $table) {
$table->increments('id');
// .. other columns
$table->timestamps();
});
}
}
You can of course just drop and not check for existence:
Schema::drop('my_table');
Read further in the docs here:
https://laravel.com/docs/5.2/migrations#writing-migrations
You may also have to consider dropping any existing foreign keys/indexes, for example if you wanted to drop a primary key:
public function up()
{
Schema::table('my_table', function ($table) {
$table->dropPrimary('my_table_id_primary');
});
Schema::dropIfExists('my_table');
}
More in the docs in dropping indexes etc here:
https://laravel.com/docs/5.2/migrations#dropping-indexes
I would like to extend the existing User model in Laravel 5.0 to add new columns to the table. How can I do so ?
Create migration by running command:
php artisan make:migration users_disabled_column
where disabled is name of column you want to add to existed table.
Edit new migration with adding column, here is example:
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class UsersDisabledColumn extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::table('users', function($table) {
$table->boolean('disabled')->default(false);
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::table('users', function($table) {
$table->dropColumn('disabled');
});
}
}
Execute created migration:
php artisan migrate
Now you can use new column:
$user = User::find($id);
$user->disabled = false;
$user->save();
