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).

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?
