1、将字符中数字转换为中文大写的数字,
注意
100==>一零零 而非==>一百
123==>一二三 而非==>一百二十三
CREATE FUNCTION Fn_NumberConvertChinase(@number NVARCHAR(50)) RETURNS NVARCHAR(20) AS BEGIN DECLARE @res NVARCHAR(20) DECLARE @char CHAR(1) SET @res = '' SET @char = substring(@number,1,1) SELECT @res = (CASE @char WHEN '1' THEN '一' WHEN '2' THEN '二' WHEN '3' THEN '三' WHEN '4' THEN '四' WHEN '5' THEN '五' WHEN '6' THEN '六' WHEN '7' THEN '七' WHEN '8' THEN '八' WHEN '9' THEN '九' WHEN '0' THEN '零' ELSE substring(@number,1,1) END ) IF(len(@number) > 1) BEGIN SET @res = @res + dbo.fn_numberconvertchinase(substring(@number,2,len(@number)-1)) END RETURN @res END
2、获取字符首字母,并转大写
CREATE FUNCTION Fn_GetPy(@str NVARCHAR(4000)) RETURNS NVARCHAR(4000) AS BEGIN DECLARE @strlen INT; DECLARE @re NVARCHAR(4000); --字符中数字转大写 SELECT @str=dbo.fn_numberconvertchinase(@str); DECLARE @t table(chr nchar(1) collate Chinese_PRC_CI_AS,letter nchar(1)) INSERT INTO @t(chr,letter) 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(UPPER(@re)) END
