改變SQL Server數據庫排序規則

Question

是否有可能改變整理數據庫下的所有對象？

例如，如果我更改數據庫排序規則，它應該改變所有的對象（表，特效等）與該數據庫。

Answer 1

我有這個問題，前一段時間，當我們改變了底層數據庫支持Unicode和需要改變舊的數據庫上的字符集，以支持匈牙利。

該腳本將讓你很長的路要走改變整理;您將需要手動更改主DB數據集。我不必長時間運行它，它不能修復任何計算列，但可能還有其他問題。不要在沒有經過測試的情況下在實時數據庫中運行它 - 您可能想要選擇它所做的更改，以便您可以審覈或找出稍後錯過的更改。

Declare 
    @NewCollation varchar(255), @DBName sysname 
Select @NewCollation = 'Latin_1_CI_AI', -- change this to the collation that you need 
     @DBName = DB_NAME() 

Declare 
    @CName varchar(255), @TbleName sysname, @objOwner sysname, @Sql varchar(8000), @Size int, @Status tinyint, @Colorder int 

Declare CurWhileLoop cursor read_only forward_only local 
for Select 
     QUOTENAME(C.Name) 
     ,T.Name 
     ,QUOTENAME(U.Name) + '.' +QUOTENAME(O.Name) 
     ,C.Prec 
     ,C.isnullable 
     ,C.colorder 
    From syscolumns C 
     inner join systypes T on C.xtype=T.xtype 
     inner join sysobjects O on C.ID=O.ID 
     inner join sysusers u on O.uid = u.uid 
    where T.Name in ('varchar', 'char', 'text', 'nchar', 'nvarchar', 'ntext') 
     and O.xtype in ('U') 
     and C.collation != @NewCollation 
    and objectProperty(O.ID, 'ismsshipped')=0 
    order by 3, 1 

open CurWhileLoop 
SET XACT_ABORT ON 
begin tran 
fetch CurWhileLoop into @CName, @TbleName, @objOwner, @Size, @Status, @Colorder 
while @@FETCH_STATUS =0 
begin 
    set @Sql='ALTER TABLE '+@objOwner+' ALTER COLUMN '+@CName+' '+@TbleName+ isnull ('(' 
+convert(varchar,@Size)+')', '') +' COLLATE '+ @NewCollation 
+' '+case when @Status=1 then 'NULL' else 'NOT NULL' end 
    exec(@Sql) -- change this to print if you need only the script, not the action 
    fetch CurWhileLoop into @CName, @TbleName, @objOwner, @Size, @Status, @Colorder 
end 
close CurWhileLoop 
deallocate CurWhileLoop
