I got the String “Pring Kea” in my Database, that it’s not show the space or character code infront of that string.
So when copy and paste in OpenOffice, its display like this “##Pring Kea”.
But when i copy into Excel, it’s display like this “_x001F__x001F_Pring Kea”.

So i want to Remove or Trim the string that is hidden infront of “Pring Kea”.
Do you have any solution for this…?

Thank…

Not the same output. You can see it from the following example

SELECT ‘a’+RTRIM(LTRIM(‘ Word ‘))+’a’ AS Answer
SELECT ‘a’+((‘ Word ‘))+’a’ AS Answer

Hi,

just now am learning about the SQL server, I cant understand exactly. I ned more explanation. i did with this example :
SELECT RTRIM(LTRIM(‘ Word ‘)) AS Answer

Output : word

But without giving the keywords also same output is generating, wats the difference.
SELECT ((‘ Word ‘)) AS Answer

Output : word – Same output

– Declare the return variable here

Declare @Lng smallint=0;
Declare @St nvarchar(max)=”;
Declare @comm nvarchar(1)=”;
Declare @i smallint=0;
Declare @Asc smallint=0;
Set @Lng=Len(@Deli_Str);

Begin
set @i=0;
While @i<=@Lng
Begin
Set @comm=substring(@Deli_Str,@i,1);
Set @Asc=Ascii(@comm);
If(@Asc!=44)

No this is fundamentally incorrect. Even the verb “to trim” means to cut off the bit around the edge (like a haircut trim – doesn’t mean to shave off all the hair!). Trim in every language (and other RDBMS I’ve used – and I’ve used a lot) means to cut of white space at eaither end, NOT to remoave all white space. There is already a function to do the latter: Remove (or Replace language/RDBMS dependant). LTRIM(RTIM(‘ string ‘)) is the right way to go, and has little overhead above ‘Trim’ as both require a by-char scan until first non-blank is reached (Rtirm obviously runs backwards from the end).

Yes it will work for nvarchar too. What di you mean by it is not working?

I tried for a column but its not working
query used: select LTRIM(RTRIM(Col1)) from [TABLE] order by Col1

Hi Pinal,

Did SQL 2008 eliminates the empty space in the right side by default? Coz while executing the below queries, i have got the same result

Select Len(‘ trail test’)
Select Len(‘ trail test ‘)

trim() function should remove any space and not only those on left or on right of the string. this is not trim().

If Microsoft will one day understand how to implement BASIC BASIC functions like TRIM, that alone will be worth a new SQL Server release :P

Speaking of which, are there cases where people actually only need LTRIM or RTRIM, and not TRIM?
