更改列類型tinyInteger

Question

嘗試在Laravel 5.2遷移數據列類型更改爲tinyInteger：

<?php 

use Illuminate\Database\Schema\Blueprint; 
use Illuminate\Database\Migrations\Migration; 

class AlterTableNameTableChangeNotificationSentTinyint extends Migration 
{ 
    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     Schema::table('table_name', function ($table) { 
      $table->tinyInteger('column_name')->default(0)->change(); 
     });  
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     // 
    } 
} 

我得到一個錯誤：

Doctrine\DBAL\DBALException]                                        
    Unknown column type "tinyinteger" requested. Any Doctrine type that you use has to be registered with \Doctrine\DBAL\Types\Type::addType().   You can get a list of all the known types wit 
    h \Doctrine\DBAL\Types\Type::getTypesMap(). If this error occurs during database introspection then you might have forgot to register all database types for a Doctrine Type. Use Abstrac 
    tPlatform#registerDoctrineTypeMapping() or have your custom types  implement Type#getMappedDatabaseTypes(). If the type name is empty you might have a problem with the cache or forgot so 
    me mapping information. 

難道我做錯了什麼？

Answer 1

事實上主義DBAL不支持tinyint你可以從他們的文檔here

不幸的是讀爲好，laravel指出，tinyint不能改變。檢查here

我需要有人證明這是錯誤的，因爲我必須使用smallInteger因爲我的項目之一的這個問題。我想也許boolean()可能是解決方案。我還沒有嘗試過。

Answer 2

試試這個 架構::表（ '表名'，函數（藍圖$表）{$ 表 - > tinyInteger（ 'COLUMN_NAME'） - >默認值（0） - >更改（）;

Answer 3

我希望，這將解決您的問題

DB::statement("ALTER TABLE table_name CHANGE COLUMN column_name column_name TINYINT UNSIGNED NOT NULL");
