Q:

Is there any difference between LTRIM(RTRIM(MyColumn1)) and TRIM(MyColumn1)?

Is there any difference between these two?
LTRIM(RTRIM(MyValue1))

TRIM(MyValue1)

I see a lot of examples that use LTRIM(RTRIM(MyValue1)), but my understanding is that this is equivalent to TRIM(MyValue1).
Am I missing something here (or was TRIM() introduced just recently which resulted in all of the examples that use LTRIM/RTRIM)?
Thank you in advance.

environment: SQL Server 2014 standard edition
