I need to CONCAT
two fields, if they both exist and add parentheses around the second field. Otherwise I just need to list the first field.
Here's the simple version:
SELECT id, CONCAT(name,' (',nickname,')') as name FROM user;
As long as name and nickname both exist you should get results like:
1 | Adam (Alpha Dog)
2 | Bob (Bobby)
3 | Charles (Charlie)
But if there is no nickname it just skips the whole thing as null
. For example: id 4
, name Doug
, nickname null
gives the result:
4 | null
What I'd like to see is it to list just the name... like this:
4 | Doug
So I started looking at CONCAT
IFNULL
. But I'm having a hard time getting it right. Can you help?
Here are a few examples of things I've tried:
SELECT id, CONCAT(IFNULL(name, ' (', nickname, ')', name) as name FROM user;
SELECT id, CONCAT(name, IFNULL(' (', nickname, ')')) as name FROM user;
