Concatenation
Simple text functions
How to modify strings
Instruction
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().
Exercise
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).
