如果你想从字符串中删除空格，-和另一个文本，那么使用以下命令:

假设您的表格中有一个手机号码，如“718-378-4957”或 ' 7183784957'，你想要替换并获得手机号码，然后使用下面的文本。

select replace(replace(replace(replace(MobileNo,'-',''),'(',''),')',''),' ','') from EmployeeContactNumber

结果:——7183784957

简单地替换它;

SELECT REPLACE(fld_or_variable, ' ', '')

编辑: 澄清一下;它是一个全局替换，不需要trim()或担心char或varchar的多个空格:

create table #t (
    c char(8),
    v varchar(8))

insert #t (c, v) values 
    ('a a'    , 'a a'    ),
    ('a a  '  , 'a a  '  ),
    ('  a a'  , '  a a'  ),
    ('  a a  ', '  a a  ')

select
    '"' + c + '"' [IN], '"' + replace(c, ' ', '') + '"' [OUT]
from #t  
union all select
    '"' + v + '"', '"' + replace(v, ' ', '') + '"'
from #t 

结果

IN             OUT
===================
"a a     "     "aa"
"a a     "     "aa"
"  a a   "     "aa"
"  a a   "     "aa"
"a a"          "aa"
"a a  "        "aa"
"  a a"        "aa"
"  a a  "      "aa"

T-sql replace http://msdn.microsoft.com/en-us/library/ms186862.aspx

代表(val， '， '， ')

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”

谢谢

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
