I am using Laravel 5.2. I have created basic tables using migration method. But now I need to add another extra table. After creating my schema, I have given php artisan migrate command. But it shows error like base table or view already exists Table:Users. I know why this happen. The migration command trying to recreate the table which already have. But I need to add another extra table in Laravel via Migration. I have gone through this https://laravel.com/docs/5.2/migrations But I can't get any solution.
If you want to create another table, just create new migration and run it.
If you're trying to add columns into existinng table, use Schema::table instad of Schema::create.
Schema::create('articles', function (Blueprint $table) {
$table->increments('id');
$table->string('title');
}
Schema::table('articles', function (Blueprint $table) {
$table->string('description');
}
If you already executed php artisan migrate then next time it will give you error saying "Table already exists.".
So if you want to execute only a particular migration then either you can temporarily move all migration's php file which are executed, out of database/migrations folder and then execute
php artisan migrate
or
you can execute migration from tinker i.e. first execute php artisan tinker and then execute content of up method from the migration but without parameter type Blueprint.
Eg.
If following is your migration up method content
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password', 60);
});
then you will have to execute
Schema::create('users', function ($table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password', 60);
});

My problem is quite simple, but I can't find any answer for this specific issue.
The thing is, I have this migration in Laravel:
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name')->unique();
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
//$table->string('guid');
$table->boolean('verified')->default('0');
$table->integer('tribe_id')->length(10)->unsigned()->default('1');
$table->boolean('admin')->default('0');
$table->rememberToken();
$table->timestamps();
});
Schema::table('users', function($table) {
$table->foreign('tribe_id')->references('id')->on('tribes')->onDelete('cascade');
});
}
As you can see I have one field commented. But when I remove the // and run the migration (on a clean DB) and when I try to perform login it returns this:
lluminate \ Database \ QueryException (HY000)
SQLSTATE[HY000]: General error: 2057 A stored procedure returning result sets of different size was called. This is not supported by libmysql (SQL: select * from `users` where `email` = email#email.com limit 1)
The major part of this auth code is generated by default Laravel artisan make:auth command.
The thing is, I already have some extra fields and it does work, but for some reason when I add the 'guid' new one (or another one, it doesn't matter the name) it breaks something I missing...
EDIT: It has something to do with MySQL database. I changed this from Shared Hosting MariaDB server to Google Cloud (5.7) and it's working...
EDIT2: Solved it by creating another database with another name (recreating with the same name didn't work) and it started working again...
Schema::table('users', function(Blueprint $table) {
$table->foreign('tribe_id')->references('id')->on('tribes')->onDelete('cascade');
});
try to put Blueprint in table like this...
or you can put the line $table->foreign()... inside the create method..
I created an app in Laravel. In the beginning, I made a migration with the following content:
public function up()
{
Schema::create('kundens', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->unsignedInteger('user_id');
$table->string('vorname');
$table->string('nachname');
$table->string('strasse');
$table->integer('plz');
$table->string('wohnort');
$table->string('mail');
$table->integer('telefon');
$table->string('geburtsdatum');
});
}
No I want to add some tables like kaufpreis or "modernisierung". I added them under the other tables but when I save the file and write in the terminal I get the error:
nothing to migrate.
So now how can I add some tables for more information?
You should create a new migration for kaufpreis and modernisierung.
The main migration for kundens did already run (see migrations table).
php artisan migrate:fresh is also an option, if you are developing locally.
Don't do this when you work with other people / production as it will erase the tables and create new ones (data will be lost)
I am working on some database migrations in Laravel 5.4. The migrations work fine with a MySQL database, but for testing I want to use SQLite but the migration fails. Here's the code
public function up()
{
Schema::create('mapped_venues', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('upload_job_id')->nullable();
$table->string('venue')->default('');
$table->unsignedInteger('venue_id')->nullable();
$table->timestamps();
$table->index(['venue']);
});
Schema::create('mapped_teams', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('upload_job_id')->nullable();
$table->string('team')->default('');
$table->unsignedInteger('team_id')->nullable();
$table->timestamps();
$table->index(['team']);
});
}
When I run php artisan migrate the index on the mapped_teams.team column is not created, but the one on mapped_venues.venue is!!
$ sqlite3 database/database.sqlite
SQLite version 3.19.3 2017-06-08 14:26:16
Enter ".help" for usage hints.
sqlite> .indexes mapped_teams
sqlite> .indexes mapped_venues
mapped_venues_venue_index
sqlite>
I have also tried to create the indexes on a separate call
Schema::table('mapped_venues', function (Blueprint $table) {
$table->index(['venue']);
});
Schema::table('mapped_teams', function (Blueprint $table) {
$table->index(['team']);
});
But the result is the same. Interestingly though, when (by mistake) I left the creation of the index $table->index['team']) inside the call to create the table (so, I have two calls to create the index) I get the error that the index mapped_teams_team_index already exists.
I am using:
Laravel 5.4.36
Doctrine DBal 2.6.2
SQLite 3.19.3
It seems like you have small mistake when calling the index function (used it as an array instead of a function):
$table->index['venue'];
should be:
$table->index('venue');
I have actually found out that the index was indeed created. I had another migration to rename the team column to mapped_team, and I wanted to remove the index first
Schema::table('mapped_teams', function (Blueprint $table) {
$table->dropIndex(['team']);
$table->renameColumn('team', 'mapped_team');
$table->index(['mapped_team']);
}
The line where the index is dropped complained that the index mapped_teams_team_index didn't exist. I have modified my migration to not drop and recreate the index, but just rename it. The result is that the index named mapped_teams_team_index still exists but it now, correctly, indexes the mapped_team column. This works on both Mysql and SQLite.
I want to add another column to my database table users. I made a new migration named Modify_users_tablewhich has the code to add the column. There is nothing wrong with the source code because I used it before, but it gives me an error that something is wrong with the table roles? How can I solve this? Here is the error and the code that is related to the error
Here is the migration Roles:
public function up()
{
Schema::create('roles', function (Blueprint $table) {
$table->string('role_name')->length(55)->unique();
$table->increments('id');
$table->timestamps();
});
}
You've got a number of problems. Your main problem is that you aren't adding a column to a table. Your script is instead trying to create a new table, as seen in this line:
Schema::create('roles', function (Blueprint $table) {
You said you are trying to add a column to the users table, but you aren't even working with the user's table: you are instead creating a table called roles which already exists. The simplest solution is to do what Dhaval suggests: ditch the migration you are added, update the migration that creates the user tables, nuke and start over.
The "right" answer is to create a new migration and put in the instructions to add the column to the users table as well as instructions on removing it. Then you can just do a simple migration instead of nuking your database. That would look something like this:
public function up()
{
Schema::table('users', function ( Blueprint $table ) {
$table->string('last_name')->after( 'first_name' )->default( '' );
});
}
public function down()
{
Schema::table( 'users', function ( Blueprint $table ) {
$table->dropColumn( ['last_name'] );
});
}
You need to run
php artisan migrate:rollback
if that also fails just go in and drop all the tables which you may have to do as it seems your migration table is messed up or your roles table when you ran a previous rollback did not drop the table.
or you can use migrate:reset command will roll back all of your application's migrations:
php artisan migrate:reset
I had the same issue and I tried something like this and it works perfect for me. My Laravel version is 5.5.
public function up()
{
Schema::connection('mysql2')->create('images', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('image');
$table->timestamps();
});
}
public function down()
{
Schema::connection('mysql2')->dropIfExists('images');
}
I had to connections in my project one is mysql and other is mysql2 becuase my project is for database with multiple connections.
So my solution is that to try specifying the connection to your database in the function.
By default connection is mysql if you havent specifed it in the function, Example is given below. Hope this helps!
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email',60)->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
public function down()
{
Schema::dropIfExists('users');
}
And so when you migrate using php artisan it doesn't show errors,
remove the table from the database ( I did it manually the first time I had this issue)
and make this change in the create_users_table migration as such
$table->string('email', 60)->unique();
and this worked for me..
Hope this helps you as well
I am new to Laravel and I create a users table using php artisan migrate command:
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->string('username');
$table->string('email');
$table->string('password');
$table->rememberToken();
});
After that I just needed to change the username column as first_name then I change the schema as follows:
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->string('first_name');
$table->string('email');
$table->string('password');
$table->rememberToken();
});
If I run the php artisan migrate command again, it says Nothing to migrate, then I used rollback, and I lose all table data.. How can I edit table structure without affecting my data? I hate Laravel doc
Let's start with your schema. Your table name is users. It contains a column named username and you want to change it to first_name without losing existing data. You need to create a new migration for this change.
php artian make:migration rename_columns_to_users_table --table=users
A new migration file will be created in your migrations directory. Open it and change it like this:
Schema::table('users', function ($table) {
$table->renameColumn('username', 'first_name');
});
Save it and then again run
php artisan migrate
You column name will be renamed immediately without losing your old data. Hope you got it now.
You will find more details here: https://laravel.com/docs/5.3/migrations#renaming-columns
You should create and register new migration and use Schema::table() and renameColumn() methods to rename a column:
Schema::table('users', function ($table) {
$table->renameColumn('from', 'to');
});
To rename a column, you may use the renameColumn method on the Schema builder.
