jak zmienić collate na wszystkie kolumny bazy danych?

Zamieszczam edycję do powyższej odpowiedzi, która odnosi się do długości char i varchar, ponieważ moja poprzednia edycja wygląda jakby została odrzucona.

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 WITH(NOLOCK)
    JOIN sys.objects o WITH(NOLOCK) ON c.[object_id] = o.[object_id]
    JOIN sys.types t WITH(NOLOCK) ON c.system_type_id = t.system_type_id AND c.user_type_id = t.user_type_id
WHERE t.name IN ('char', 'varchar', 'text', 'nvarchar', 'ntext', 'nchar')
    AND c.collation_name != @collate
    AND o.[type] = 'U'

Zebrałem poniższy skrypt z różnych źródeł, które upuszczają zależności, aktualizują kolacje, a następnie odtwarzają obiekty zależne. Rozwiązuje to problem aktualizacji zestawiania kolumn, które mają zależności (indeksy, ograniczenia klucza obcego itp.)

Dzięki wszystkim za sugestię, to pomaga mi lot podczas migracji mojej bazy danych z SQL Server 2008 R2 do 2014

Uwaga: niektóre zapytania mają nieprawidłowy VARCHAR ( - ), zmieniłem go na VARCHAR(MAX) i działa dobrze.

Kroki do zmiany zestawienia:

1. Uruchom powyższe zapytanie i uzyskaj zapytanie Alter table
2. upuść wszystkie indeksy tabel i funkcji wartych tabel
3. Uruchom wygenerowane zapytanie kroku 1
4. tworzenie indeksów tabel i tabel wartościowane funkcje.

Podczas gdy żadne inne podejście nie działało dla mnie, Ten artykuł autorstwa Douglasa P. Castilho dostarczył mi kompletnego rozwiązania. Dzielę się nim na wypadek, gdyby komuś to pomogło.

1. Tworzenie kopii zapasowych wszystkich baz danych.
2. Zatrzymaj usługi SQL Server na serwerze.
3. Otwórz wiersz polecenia i przejdź do katalogu Binn, jak

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

1. Wykonaj polecenie poniżej, aby zastosować nowe zestawienie.

Sqlservr-m-t4022-t3659-q"[Enter Collation Name] "

1. Uruchom ponownie usługę SQL Server.

To jest to.

Przed wykonaniem tej operacji przeczytaj najpierw ten artykuł. https://www.mssqltips.com/sqlservertip/3221/how-to-change-the-collation-of-a-sql-server-column/

Po przeczytaniu powyższego artykułu i upewnij się, że usunąłeś poniższe referencje z bazy danych.

• kolumna obliczeniowa
• statystyki rozkładu indeksu, albo generowane automatycznie lub za pomocą instrukcji CREATE STATISTICS
• ograniczenie kontroli
• KLUCZ OBCY constraint

Kliknij poniższy skrypt w swojej bazie danych po tym nie zapomnij zmienić również zestawiania bazy danych.
