在sql中創(chuàng)建用戶自定義拼音函數(shù)： 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 '發(fā)','F' union all select '旮','G' union all select '鉿','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 --測試 select dbo.f_GetPy('東莞市') as 東莞市,dbo.f_GetPy('ab中c國人') as 中國人

--以后查詢的時(shí)候,就可以調(diào)用上面的函數(shù)來實(shí)現(xiàn)漢字模糊查詢

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