How to modify strings


Very well done! Now that we understand the concatenation operator, let's learn some string functions. Our database provides many of these. For instance, there is a function called length(), which shows the length of a string column. For example:

SELECT length(first_name) AS first_name_length
FROM copywriter;

will show 4 for the name 'Kate', because 'Kate' consists of 4 letters.

In SQL Server this function is called len().


For every slogan, show its id, its text, and its length. Name the last column text_length.

Stuck? Here's a hint!

Use length(text).
