909 PointsHow do I write a query that will add <> to the data in a specific column in my query results?
I need the emails in my query results to be within the left and right arrow symbols.

Supposing you have a column called "email" in a "customers" table...
SELECT "<" || email || ">" FROM customers;
You can learn more about it here: https://teamtreehouse.com/library/reporting-with-sql/working-with-text/-adding-text-columns-together
Hope it helps!

IN MS SQL Server it would be:
'<' + email + '>'
IN MySQL it would be:
CONCAT( '<', email, '>')

Courses Plus Student 22,744 PointsThat's right! Thanks for the clarification Andrew. It's also explained in the course titled "Reporting with SQL", unit "Working with Text", step "Concatenating Text" (that's where the link I provided points to). I also recommend taking the "Database Foundations" course after this one to learn more about DML (Data Manipulation Language) and start getting your feet wet with DDL (Data Definition Language), which it's not taught in the other database courses (such as "SQL Basics").
