I have columns as mentioned bellow:

public function up()
{
    Schema::create('stnk', function(Blueprint $table)
    {
        $table->increments('id');
        $table->string('no_reg', 50)->unique();
        $table->string('no_bpkb', 50)->unique();
        $table->string('nama_pemilik', 100);
        $table->string('alamat');
        $table->string('merk', 50);
        $table->string('tipe', 50);
        $table->string('jenis', 50);
        $table->smallInteger('tahun_pembuatan');
        $table->smallInteger('tahun_registrasi');
        $table->smallInteger('isi_silinder');
        $table->string('no_rangka', 50);
        $table->string('no_mesin', 50);
        $table->string('warna', 50);
        $table->string('bahan_bakar', 50);
        $table->string('warna_tnkb', 50);
        $table->string('kode_lokasi', 50);
        $table->date('berlaku_sampai');
        $table->timestamps();

        $table->index('created_at');
        $table->index('updated_at');
    });

}

I have made seeder to stnk table

Now I want to rename id to id_stnk.
I've added a "doctrine / dbal" in the "composer" and do a composer update.

I've made migration php artisan migration:make rename_column.
Then I've added new method to rename_column:

Schema::table('stnk', function(Blueprint $table)
{
    $table->renameColumn('id', 'id_stnk');

});

And then I've tried to run command php artisan migrate but I got error as mentioned bellow:

[Ulluminate\Database\QueryException]
SQLSTATE[HY000]: General error: 1025 Error on rename of './my_database/#sql -447_33' to './my_database/stnk' (error: 150) (SQL: ALTER TABLE stnk CHANGE id id_stnk INT UNSIGENED AUTO_INCREMENT NOT NULL)

[PDOException]

You need to create another migration file - and place it in there:

Run

Laravel 4:    php artisan migrate:make rename_stnk_column
Laravel 5:    php artisan make:migration rename_stnk_column

Then inside the new migration file place:

class RenameStnkColumn extends Migration
{

    public function up()
    {
        Schema::table('stnk', function(Blueprint $table) {
            $table->renameColumn('id', 'id_stnk');
        });
    }


    public function down()
    {
        Schema::table('stnk', function(Blueprint $table) {
            $table->renameColumn('id_stnk', 'id');
        });
    }

}
