I'm not understanding how to only show the first initial of someone's name using the SUBSTR function.

https://teamtreehouse.com/library/reporting-with-sql/working-with-text/creating-excerpts

Here is my code, I didn't include SUBSTR in my code because I need some help on how to go about doing it.

SELECT first_name AS "initial", last_name FROM customers;

SUBSTR function takes 3 parameters:

  • substr(value, start, length) - where the start is 1 index based.

So :

SELECT SUBSTR(first_name, 1, 1) as initial, last_name FROM customers;
