Databases Reporting with SQL Working with Text Finding the Length of Text

Previous exercise - Concatenate text and place <> around email address - your examples and teaching are very unclear.

Your explanation and examples as to how to concatenate a first name, last name, and email address with brackets around it are very unclear. Our DBA could not figure out what it is you wanted in the example, even after trying a dozen or more times.

Your DBA couldn't figure it out? But this is a Beginner level course!

Seriously, the challenges can sometimes be a bit tricky, but I doubt most beginners taking the course need more than a few tries to pass the challenge.

The most common causes for people asking for help is they either forget to include a space between the name and the open angle, or they don't realize they can mix literal strings and fields when concatenating.

If you couldn't solve it yourself, and the above issues don't resolve it, feel free to post your code here for some specific help.

It works like this: SELECT first_name || " " || last_name || " <" || email || ">" AS to_field FROM patrons;

Your DBA might want to consider going through the classes. The answer, while challenging, wasn't particularly difficult after a try or two.

Coding, even in SQL, is about problem solving. So it's natural and makes sense that the questions are going to require you to problem solve a bit more than what is given.

SELECT to_field AS "To", first_name || "" "" || last_name || " " || "<" || email || ">" FROM patrons;

I couldn't get this to work but not sure why. The "Alias it to the to_field" didn't make sense wince there is no to_field in the example. Error kept saying syntax error with "||"..> triple checked the spaces but still can't solve it.

The correct one is: SELECT first_name || " " || last_name || " " || "<" || email || ">" AS to_field FROM patrons;
