class ClearOldOauthRelations extends Migration

PS: usually foreign_key = column_key
ex:
Schema::table('despatch_discrepancies', function (Blueprint $table) {
$table->dropForeign(['pick_detail_id']);
$table->dropColumn('pick_detail_id');
});$table->dropIndex(['state']); // Drops index 'geo_state_index'$table->dropPrimary('users_id_primary');Schema::table('admins', function (Blueprint $table) { $table->dropForeign('admins_post_id_foreign'); $table->dropColumn('post_id');});
