SQL, I want just see who have in the same time

Question

I have this table:

TABLE tb_players (
    "idPlayer" BIGINT, 
    "flFacebook" BIGINT, 
    "flTwitter" BIGINT, 
    "flTwitch" BIGINT, 
    "descCountry" TEXT, 
    "dtBirth" TEXT, 
    "dtRegistration" TEXT

I did this:

SELECT SUM(flFacebook) AS totalFB,
       SUM(flTwitter) AS totalTwitter,
       SUM(flTwitch) AS totalTwitch

FROM tb_players

totalFB	totalTwitter	totalTwitch
63	44	53

And I want just see who have in the same time:

flFacebook, flTwitter, flTwitch

How do it? I try this:

SELECT 
    SUM(flFacebook), SUM(flTwitter), SUM(flTwitch)
FROM 
    tb_players
INNER JOIN 
    flFacebook 
        ON(
            (tb_players.flTwitter) 
            AND
                (tb_players.flTwitch))

But not work
