Putting it all together

In this exercise, we are going to use the film and category tables to create a new field called film_category by concatenating the category name with the film's title. You will also practice how to truncate text fields like the film table's description column without cutting off a word.

To accomplish this we will use the REVERSE() function to help determine the position of the last whitespace character in the description before we reach 50 characters. This technique can be used to determine the position of the last character that you want to truncate and ensure that it is less than or equal to 50 characters AND does not cut off a word.

This is an advanced technique but I know you can do it! Let's dive in.

Instructions
100 XP
  • Get the first 50 characters of the description column
  • Determine the position of the last whitespace character of the truncated description column and subtract it from the number 50 as the second parameter in the first function above.
