在上篇MS SQL 排序规则总结中,大致就数据库服务器排序规则(或者叫数据库实例排序规则)、数据库排序规则、列的排序规则粗浅的叙说了一遍,重点讲述了修改数据库服务器排序规则(数据库实例排序规则),其中对于数据库排序规则的修改只是粗略带过。其实相对而言,修改服务器排序规则(数据库实例排序规则)相对简单一些,修改数据库的排序规则就复杂多了,因为涉及到数据、SQL脚本等等,例如,一不小心,修改排序规则后,数据当中可能就会出现乱码; 另外,修改数据库排序规则麻烦的是要大量修改相关表的字段的排序规则,如果不用脚本批量处理,那么这项工作想想就让人望而生畏。做这项工作前,一定要做好备份或在测试服务器测试通过后,然后进行数据库排序规则修改。

如果要首先了解一下修改排序规则,首先看看MS SQL 排序规则总结当中的介绍,重复的内容就不做过多介绍了。我们首先来看看,修改排序规则当中会遇到哪些问题吧。

DBMonitor数据库的排序规则为 Chinese_PRC_CI_AS,在数据库中创建TEST表,插入数据后,修改其排序规则为SQL_Latin1_General_CP1_CI_AS,然后

   1: USE DBMonitor; 
   2:  
   3: GO 
   4:  
   5: CREATE TABLE TEST 
   6:  
   7: ( 
   8:  
   9:  ID INT , 
  10:  
  11:  NAME VARCHAR(12), 
  12:  
  13:  CITY NVARCHAR(12) 
  14:  
  15: ) 
  16:  
  17: CREATE INDEX IDX_TEST_NAME ON TEST(NAME); 
  18:  
  19: CREATE INDEX IDX_TEST_CITY ON TEST(CITY);
  20:  
  21: INSERT INTO TEST 
  22:  
  23: …..
  24:  
  25: ALTER DATABASE DBMonitor COLLATE SQL_Latin1_General_CP1_CI_AS 
  26:  

修改排序规则后,你会发现数据库当中,修改排序规则前新建的表,其列的排序规则依然是旧的排序规则,当然,有时候它不会有任何影响,但是有时候也会导致SQL脚本中出现排序规则冲突等错误。

SELECT object_id,name, collation_name FROM sys.columns WHERE object_id =OBJECT_ID('TEST')

如上所示,修改列的排序规则当中,如果在这个字段上建有索引,那么修改列的排序规则时,就会报上面错误信息。这时需要先删除索引,修改列的排序规则后,然后重建索引。

所以要彻底修改这些列的排序规则,这项工作相当的繁琐和郁闷,还是推荐大家看看这位兄台的Easy way to change collation of all database objects in SQL Server的博客,由于这篇博客里面有些脚本没有写全,有些脚本我稍作了修改,例如将生成创建表索引、约束、删除表相关索引、约束的脚本写入表里面。Fix了一些小bug,至于还有没有其它bug,暂时还没有发现,如果大家有发现其它bug,欢迎指出错误。

修改数据库的排序规则时,按如下步骤顺序执行SQL

   1:  
   2: ALTER DATABASE DataBase COLLATE Chinese_PRC_CI_AS
   3:  
   4: EXEC  sp_change_collation_script 'Chinese_PRC_CI_AS';
   5:  
   6: --执行下表里面的SQL语句
   7: SELECT * FROM dbo.DropTableKeys
   8:  
   9: --执行下表里面的SQL语句
  10: SELECT * FROM ChangeColCollation
  11:  
  12: --执行下表里面的SQL语句
  13: SELECT * FROM dbo.CreateTableKeys

 

最后验证没有问题后,可以删除dbo.CreateTableKeys、dbo.DropTableKeys、dbo.ChangeColCollation等表。修改数据库的排序规则完成。
