L TRIM removes all the white space from the starting of the pattern and R TRIM removes all the white space at the end of the pattern.:-)
Sorry, but that's factually incorrect for SQL Server. For SQL, LTRIM and RTRIM affect only spaces
, not all whitespace characters.
SQL DBA,SQL Server MVP(07, 08, 09) Prosecutor James Blackburn, in closing argument in the Fatal Vision murders trial:
If in the future, you should cry a tear, cry one for them [the murder victims]. If in the future, you should say a prayer, say one for them. And if in the future, you should light a candle, light one for them.
