Trimming strings II
In the previous exercise, you used TRIM() to remove the leading and trailing spaces for the values of the airport_name column.
Suppose that the TRIM() function is not available because you are using an older version of SQL Server 2017, so you this time you need to use LTRIM() and RTRIM().
How can you remove these extra spaces?
