Only showing first result from "WHERE" clause.

Hi, i'm trying to query some data from my built database and for some reason i'm only able to retrieve what is outlined first in the where clause.

EX - SELECT Name, team, PPG FROM player_stats WHERE team = "ATL" OR "BOS" OR "DEN";

I'm able to see all information requested, but only for players from "ATL" or Atlanta. Is there any reason as to why this is happening? Same thing happens when attempting to join tables as well.

Any info would be greatly appreciated. Thank you!

Hi Matt,

Have you tried?

SELECT Name, team, PPG FROM player_stats WHERE team = "ATL" OR team = "BOS" OR team = "DEN";

OR (probably better):

SELECT Name, team, PPG FROM player_stats WHERE team in ("ATL" "BOS" "DEN");

Let me know

I was thinking Matt might like to try solving this for himself using a few hints instead of getting a complete answer.

Thanks guys, the mysql syntax is just a little different than what i'm used to. "IN" expression has been covered too! Thank you!

You can only combine complete expressions.

So for example, you can't write :point_right: team = "ATL" OR "BOS" OR "DEN"
but you could write :point_right: team = "ATL" OR team = "BOS" OR team = "DEN".

But in this case, you might want to take advantage of a different kind of expression that uses multiple terms. Has the course covered the use of "IN" yet?
