[日期:2013-03-25] 来源:  作者: [字体: ]

操作步骤1:生成获取中文字符串对应的拼音首字母字符串函数

操作步骤2:执行重命名中文字段名为拼音字首母字段名脚本

--1、SQL获取中文字符串对应的拼音首字母字符串函数
Create  function fun_getPY
 (
    @str nvarchar(4000)
 )
returns nvarchar(4000)
as
begin
  declare @word nchar(1),@PY nvarchar(4000)

  set @PY=''

  while len(@str)>0
  begin
    set @word=left(@str,1)

    --如果非汉字字符,返回原字符
    set @PY=@PY+(case when unicode(@word) between 19968 and 19968+20901
               then ( 
                            select top 1 PY 
                            from 
                            ( 
                             select 'A' as PY,N'驁' as word
                             union all select 'B',N'簿'
                             union all select 'C',N'錯'

                      ) T 
                   where word>=@word collate Chinese_PRC_CS_AS_KS_WS 
                   order by PY ASC
                          )

  end

  return @PY

end

--查询当前数据库中的所有中文字段名列表
select b.name as tablename,a.name as columnname from sys.columns a left join sys.objects b on a.object_id=b.object_id  where UNICODE(a.name) BETWEEN 19968 AND 19968+20901 order by b.name

--定义游标查询变量
declare @TableName nvarchar(250)
declare @ColumnName nvarchar(250)

--声明读取数据库所有数据表名称游标mycursor1
declare mycursor1 cursor for select b.name as tablename,a.name as columnname from sys.columns a left join sys.objects b on a.object_id=b.object_id  where UNICODE(a.name) BETWEEN 19968 AND 19968+20901 order by b.name

 --打开游标
open mycursor1
--从游标里取出数据赋值到我们刚才声明的数据表名变量中
fetch next from mycursor1 into @TableName,@ColumnName
--如果游标执行成功 
while (@@fetch_status=0)
begin 

 --定义重命名字段变量
declare @NewColumnName varchar (250)
select @NewColumnName=dbo.fun_getPY(@ColumnName)

declare @renameCommand nvarchar(2000)
set @renameCommand=@TableName+'.'+@ColumnName

--指定重命名字段指令
exec sp_rename @renameCommand,@NewColumnName,'column'

 --用游标去取下一条记录
    fetch next from mycursor1 into @TableName,@ColumnName
end

--关闭游标
close mycursor1
--撤销游标
deallocate mycursor1

--查询重命名后的当前数据库中的所有中文字段名列表
select b.name as tablename,a.name as columnname from sys.columns a left join sys.objects b on a.object_id=b.object_id  where UNICODE(a.name) BETWEEN 19968 AND 19968+20901 order by b.name
