Write a query to show a list of track names from the Track table, sorted in ascending order of name.
The order looks a bit odd...
Some tracks have a leading space in their name, meaning that the list isn't sorted quite as we want it. Add a calculated column which trims the track names and use this new column to sort the results.
We're getting closer to the order we want.
Some track names are wrapped in double quotes while others aren't. Add a calculated column which both trims the track name and replaces any double quote with an empty string. Sort the results in ascending order of this new column.
Another change to the order of the tracks.
Add a WHERE clause which returns tracks whose cleaned up name begins with A.
Using the original Track_name, these three songs would be in different positions in the list.
Save the script as Track Trimming.sql and then close it.
