照合順序をデータベースのすべての列に変更する方法は？

Question

データベースのすべてのテーブルのすべての列の照合順序を変更したいと思います。スタックオーバーフローの他の投稿で、このスクリプトを見つけました：（ post ）

SELECT 'ALTER TABLE [' + SYSOBJECTS.Name + '] ALTER COLUMN [' + SYSCOLUMNS.Name + '] ' +
SYSTYPES.name + 
    CASE systypes.NAME
    WHEN 'text' THEN ' '
    ELSE
    '(' + RTRIM(CASE SYSCOLUMNS.length
    WHEN -1 THEN 'MAX'
    ELSE CONVERT(CHAR,SYSCOLUMNS.length)
    END) + ') ' 
    END

    + ' ' + ' COLLATE Latin1_General__CI_AI ' + CASE ISNULLABLE WHEN 0 THEN 'NOT NULL' ELSE 'NULL' END
    FROM SYSCOLUMNS , SYSOBJECTS , SYSTYPES
    WHERE SYSCOLUMNS.ID = SYSOBJECTS.ID
    AND SYSOBJECTS.TYPE = 'U'
    AND SYSTYPES.Xtype = SYSCOLUMNS.xtype
    AND SYSCOLUMNS.COLLATION IS NOT NULL
    AND NOT ( sysobjects.NAME LIKE 'sys%' )
    AND NOT ( SYSTYPES.name LIKE 'sys%' )
    GO

ただし、列の照合順序を見ると、照合順序が古い照合順序であることがわかります。

実際の照合はASなので、「ANIMAL」と「ÁNIMAL」を使用できます。スクリプトを実行しても、エラーは発生しません。新しい照合はAIであるため、エラーが発生すると思います。そのため、このスクリプトは何もしないと思います。

データベース内のすべてのテーブルのすべての列の照合順序を変更できるのはなぜですか？

ありがとう。

Answer 1

これを試してください-

クエリ：

DECLARE @collate SYSNAME
SELECT @collate = 'Cyrillic_General_CS_AS'

SELECT 
      '[' + SCHEMA_NAME(o.[schema_id]) + '].[' + o.name + '] -> ' + c.name
    , 'ALTER TABLE [' + SCHEMA_NAME(o.[schema_id]) + '].[' + o.name + ']
        ALTER COLUMN [' + c.name + '] ' +
        UPPER(t.name) + 
        CASE WHEN t.name NOT IN ('ntext', 'text') 
            THEN '(' + 
                CASE 
                    WHEN t.name IN ('nchar', 'nvarchar') AND c.max_length != -1 
                        THEN CAST(c.max_length / 2 AS VARCHAR(10))
                    WHEN t.name IN ('char', 'varchar') AND c.max_length != -1 
                        THEN CAST(c.max_length AS VARCHAR(10))
                    WHEN t.name IN ('nchar', 'nvarchar', 'char', 'varchar') AND c.max_length = -1 
                        THEN 'MAX'
                    ELSE CAST(c.max_length AS VARCHAR(10)) 
                END + ')' 
            ELSE '' 
        END + ' COLLATE ' + @collate + 
        CASE WHEN c.is_nullable = 1 
            THEN ' NULL'
            ELSE ' NOT NULL'
        END
FROM sys.columns c
JOIN sys.objects o ON c.[object_id] = o.[object_id]

Answer 3

依存関係を削除して照合順序を更新し、依存オブジェクトを再作成するさまざまなソースから以下のスクリプトをまとめました。これにより、依存関係（インデックス、外部キー制約など）を持つ列の照合順序を更新する問題が解決されます。

Answer 4

提案に感謝します。データベースをSQL Server 2008 R2から2014に移行する際に役立ちます。

注：結果のクエリの一部に無効なVARCHAR（-）が含まれているため、VARCHAR（MAX）に変更しましたが、正常に機能しています。

照合順序を変更する手順：

1. 上記のクエリを実行し、テーブル変更クエリを取得します
2. テーブルおよびテーブル値関数のすべてのインデックスを削除します
3. ステップ1の生成されたクエリを実行します
4. テーブルおよびテーブル値関数のインデックスを作成します。

Answer 5

他のアプローチはどれもうまくいきませんでしたが、 Douglas P. Castilhoによるこの記事 は完全なソリューションを提供してくれました。誰にも役立つ場合に備えて共有しています。

1. すべてのデータベースのバックアップを作成します。
2. サーバーでSQL Serverサービスを停止します。
3. コマンドプロンプトを開き、次のようにBinnディレクトリに移動します

C：\ Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn

4. 以下のコマンドを実行して、新しい照合を適用します。

sqlservr -m -T4022 -T3659 -q "[照合名を入力]"

5. SQL Serverサービスを再度開始します。

それでおしまい。

Answer 6

この操作を行う前に、まずこの記事をお読みください。 https://www.mssqltips.com/sqlservertip/3221/how-to-change-the-collat​​ion-of-a-sql-server-column/

上記の記事を読んだ後、データベースから以下の参照を削除したことを確認してください。

• 計算列
• 自動的に、またはCREATE STATISTICSステートメントによって生成されたインデックス分布統計
• CHECK制約
• 外部キー制約

データベースで以下のスクリプトを押して、データベースの照合も変更することを忘れないでください。

Answer 7

PHPMyAdminを使用しているこのソリューションを探している人には、「データベース操作」タブの下部にオプションがあります（最初にデータベースをクリックし、次に上部ツールバーの「操作」タブをクリックします）。照合ボックスまでスクロールし、照合を選択し、2つのチェックボックスをオンにします（最初のチェックボックスがオンの場合は1つが表示されます）。

• すべてのテーブル照合を変更する
• すべてのテーブル列の照合順序を変更する

基本的に投稿されたようなスクリプトを実行するようです。コンソールには、実行された最終コマンドが表示されます。

ALTER TABLE `DB_NAME`.`LAST_TABLE_IN_DB`DEFAULT CHARSET=utf8mb4 COLLATE utf8mb4_unicode_ci
