What is the best way to remove all spaces from a string in SQL Server 2008?
LTRIM(RTRIM(' a b '))
would remove all spaces at the right and left of the string, but I also need to remove the space in the middle.
Simply replace it;
SELECT REPLACE(fld_or_variable, ' ', '')
Edit:
Just to clarify; its a global replace, there is no need to trim()
or worry about multiple spaces for either char
or varchar
:
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
Result
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"
