根据汉字声母，要在表中找相关记录，怎么实现？比如输入"zgyh"，就能找到所有“中国银行”的记录。

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[f_GetPy]') and xtype in (N'FN', N'IF', N'TF'))
 drop function [dbo].[f_GetPy]
GO

--创建取拼音函数
create function f_GetPy(@Str nvarchar(400))
returns nvarchar(4000)
as
begin
 declare @strlen int,@re nvarchar(4000)
 declare @t table(chr nchar(1) collate Chinese_PRC_CI_AS,letter nchar(1))
 insert @t select '吖','A' union all select '八','B'
 union all select '嚓','C' union all select '咑','D'
 union all select '妸','E' union all select '发','F'
 union all select '旮','G' union all select '铪','H'
 union all select '丌','J' union all select '咔','K'
 union all select '垃','L' union all select '嘸','M'
 union all select '拏','N' union all select '噢','O'
 union all select '妑','P' union all select '七','Q'
 union all select '呥','R' union all select '仨','S'
 union all select '他','T' union all select '屲','W'
 union all select '夕','X' union all select '丫','Y'
 union all select '帀','Z'

 select @strlen=len(@str),@re=''
 while @strlen>0
 begin
  select top 1 @re=letter+@re,@strlen=@strlen-1
  from @t a where chr<=substring(@str,@strlen,1)
  order by chr desc
  if @@rowcount=0
   select @re=substring(@str,@strlen,1)+@re,@strlen=@strlen-1
 end
 return(@re)
end
go

--测试
select dbo.f_GetPy('东莞市') as 东莞市,dbo.f_GetPy('ab中c国人') as 中国人

--以后查询的时候,就可以调用上面的函数来实现汉字模糊查询

select * from 表 where dbo.f_getpy(字段)='zgyh'
