如果你需要在所有列中修剪空格，你可以使用这个脚本来动态地做它:

--Just change table name
declare @MyTable varchar(100)
set @MyTable = 'MyTable'

--temp table to get column names and a row id
select column_name, ROW_NUMBER() OVER(ORDER BY column_name) as id into #tempcols from INFORMATION_SCHEMA.COLUMNS 
WHERE   DATA_TYPE IN ('varchar', 'nvarchar') and TABLE_NAME = @MyTable

declare @tri int
select @tri = count(*) from #tempcols
declare @i int
select @i = 0
declare @trimmer nvarchar(max)
declare @comma varchar(1)
set @comma = ', '

--Build Update query
select @trimmer = 'UPDATE [dbo].[' + @MyTable + '] SET '

WHILE @i <= @tri 
BEGIN

    IF (@i = @tri)
        BEGIN
        set @comma = ''
        END
    SELECT  @trimmer = @trimmer + CHAR(10)+ '[' + COLUMN_NAME + '] = LTRIM(RTRIM([' + COLUMN_NAME + ']))'+@comma
    FROM    #tempcols
    where id = @i

    select @i = @i+1
END

--execute the entire query
EXEC sp_executesql @trimmer

drop table #tempcols

drop table #tempcols

取代()函数:

REPLACE(field, ' ', '')

100%的工作

UPDATE table_name SET  "column_name"=replace("column_name", ' ', ''); //Remove white space

UPDATE table_name SET  "column_name"=replace("column_name", '\n', ''); //Remove newline

UPDATE table_name SET  "column_name"=replace("column_name", '\t', ''); //Remove all tab

可以使用“column_name”或“column_name”

似乎每个人都在引用一个REPLACE函数。甚至多次调用REPLACE函数。但是当你有一个未知数量的空格的动态输出时，它就不起作用了。任何经常处理这个问题的人都知道REPLACE只会删除一个空格，而不是全部。LTRIM和RTRIM似乎有同样的问题。留给微软吧。 下面是一个示例输出，使用WHILE循环删除所有CHAR(32)值(空格)。

DECLARE @INPUT_VAL  VARCHAR(8000)
DECLARE @OUTPUT_VAL VARCHAR(8000)

SET @INPUT_VAL = '      C               A                         '
SET @OUTPUT_VAL = @INPUT_VAL
WHILE CHARINDEX(CHAR(32), @OUTPUT_VAL) > 0 BEGIN
    SET @OUTPUT_VAL = REPLACE(@INPUT_VAL, CHAR(32), '')
END

PRINT 'START:' + @INPUT_VAL + ':END'
PRINT 'START:' + @OUTPUT_VAL + ':END'

下面是上面代码的输出:

START:      C               A                         :END
START:CA:END

现在更进一步，在UPDATE或SELECT语句中使用它，将其更改为udf。

CREATE FUNCTION udf_RemoveSpaces (@INPUT_VAL    VARCHAR(8000))
RETURNS VARCHAR(8000)
AS 
BEGIN

DECLARE @OUTPUT_VAL VARCHAR(8000)
SET @OUTPUT_VAL = @INPUT_VAL
-- ITTERATE THROUGH STRING TO LOOK FOR THE ASCII VALUE OF SPACE (CHAR(32)) REPLACE IT WITH BLANK, NOT NULL
WHILE CHARINDEX(CHAR(32), @OUTPUT_VAL) > 0 BEGIN
    SET @OUTPUT_VAL = REPLACE(@INPUT_VAL, CHAR(32), '')
END

RETURN @OUTPUT_VAL
END

然后在SELECT或INSERT语句中使用该函数:

UPDATE A
SET STATUS_REASON_CODE = WHATEVER.dbo.udf_RemoveSpaces(STATUS_REASON_CODE)
FROM WHATEVER..ACCT_INFO A
WHERE A.SOMEVALUE = @SOMEVALUE

INSERT INTO SOMETABLE
(STATUS_REASON_CODE)
SELECT WHATEVER.dbo.udf_RemoveSpaces(STATUS_REASON_CODE)
FROM WHATEVER..ACCT_INFO A
WHERE A.SOMEVALUE = @SOMEVALUE

replace(replace(column_Name,CHAR(13),''),CHAR(10),'')
