如何替换sql表中的特殊字符并动态替换所需的字符？

时间：2016-02-08 06:50:54

标签： sql sql-server-2012

例如

'e'的'p'''' 'á'bya '¾'by'3 / 4'  óby'o'
''by'n'
'á'由'a'

不工作......但结果是我想要的。

WHILE EXSITS (SELECT id from #tmp_dirtytable)
BEGIN
-- Step 1: Read the required data row from the temp table
DECLARE @id INT
DECLARE @special_character VARCHAR(100)
DECLARE @special_character_to_replace_with VARCHAR(100)
SELECT @id = id, @special_character = special_character, @special_char_bal_bla = something from #tmp_dirtytable


-- Step 2: Write the replace logic here


-- Step 3: Delete the row that we have processed from the temp table
DELETE FROM #tmp_dirtytable where id = @id

END

如果您使用的是SQL Server，此查询将为您提供帮助

Create proc specialcharacterreplacer
@tblname varchar(1000),
@column_name varchar(1000)
as
begin
Declare @query varchar(max)
SET @query = 'UPDATE '+@tblname +' SET ' +@column_name + ' = dbo.ReplaceSpecialCharacter('+@column_name+')'
Exec(@query)
end

CREATE FUNCTION ReplaceSpecialCharacter
(
@Input varchar(max)
)
RETURNS varchar(Max)
AS
BEGIN
Declare @Result varchar(Max)
SET @Result = Replace(@Input,'è','e')
SET @Result = Replace(@Result,'á','a')
SET @Result = Replace(@Result,'¾','3/4')
SET @Result = Replace(@Result,'ó','o')
SET @Result = Replace(@Result,'ä','a')
SET @Result = Replace(@Result,'ñ','n')
SET @Result = Replace(@Result,'á','a')
Return @Result
END
