Exercise

The TRIM function

In this exercise, we are going to revisit and combine a couple of exercises from earlier in this chapter. If you recall, you used the LEFT() function to truncate the description column to 50 characters but saw that some words were cut off and/or had trailing whitespace. We can use trimming functions to eliminate the whitespace at the end of the string after it's been truncated.
