    l  今年的一项重要工作是对公司所用系统进行繁简的转换,程序转成简体基本很容易解决,但数据库转换成简体,就没那么容易了。经测试发现,简体的数据库,可以完美的支持到繁简体同时存储,并且不用更换任何数据类型,没想到SQL升级到2005后,微软如此的厚爱大陆市场,其它的话不多说了,罗列一下,本次转换数据库的相关步骤,

    从网上看到有部分好人,有相关的转换代码,其根源是老外写的,但往往直接拿来用是不行的,还必须对其进行修正,该代码只考虑了,约速束主键和外键,未考虑到检查约束,统计信息,因此决定还是写在博客中,方便日后查找,需要的同学可供参考。

    经过在网上搜索部分解决方案,在此基础上进行修正,解决方案才是正解。

                                                        2:索引type_des为HEAP的索引也会生成。

    第二步
     --3执行下表里面的SQL语句  
      SELECT * FROM dbo.DropTableKeys  
    
       
      declare @sqltemp nVARCHAR(255),@id varchar(50)
      SELECT ID=newid(),*, handle=0 into #t1 from DropTableKeys

          update #t1
          set handle=1
          where ID=@id
      end 
      drop table #t1
      
    第三步
    --4执行下表里面的SQL语句
       SELECT * FROM ChangeColCollation 
       declare @sqltemp nVARCHAR(255),@id varchar(50)
      SELECT ID=newid(),*, handle=0 into #t1 from ChangeColCollation

          set handle=1
          where ID=@id
      end 
      drop table #t1
    第四步
     --5执行下表里面的SQL语句 
       SELECT * FROM dbo.CreateTableKeys
       
    declare @sqltemp nVARCHAR(255),@id varchar(50)
    SELECT ID=newid(),*, handle=0 into #t1 from CreateTableKeys
    while ((select count(*) from #t1 where handle=0)>0)
      begin
          select top 1 @id=ID,@sqltemp=SQL_TEXT from #t1 where  handle=0
           EXEC sp_executesql @sqltemp 
          update #t1
          set handle=1
          where ID=@id
      end 
      drop table #t1
      
    第五步
    /**************************************************************************************************************************************************************/   
      
     --6 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。
    drop table CreateTableKeys
    drop table DropTableKeys
    drop table ChangeColCollation
    
    drop proc ScriptCreateTableKeys
    drop proc [sp_change_collation_script]
    drop proc ScriptDropTableKeys
    第六步
    --7部分统计信息要先删除
    /****** Object:  Statistic [hind_318_1]    Script Date: 02/18/2014 10:21:39 ******/
    if  exists (select * from sys.stats where name = N'hind_318_1' and object_id = object_id(N'[dbo].[PINVDTL]'))
    DROP STATISTICS [dbo].[PINVDTL].[hind_318_1]
    GO
    
    USE [HZEW2_CN]
    GO
    
    /****** Object:  Statistic [hind_318_1]    Script Date: 02/18/2014 10:21:40 ******/
    CREATE STATISTICS [hind_318_1] ON [dbo].[PINVDTL]([PINV])
    GO
