mysql - php variable used as mysqli column name syntax error -

-

this question has answer here:

this think it´s problem...

$sql1 = "select `puntos_globales`, '$juego'           `lista_jugadores` `id_jugador`='$notop'";

this error message:

error: 

you have error in sql syntax; check manual corresponds mysql server version right syntax use near "blackops2'='1' `id_jugador` = '10" @ line 1

$juego .. php variable holds column name; in case blackops2. don´t know why in error says blackops2'='1'??

from error seems didnt provide true query , looks have 2 clause 

     blackops2='1' `id_jugador` = '10"

try that

     `id_jugador` = '10' , blackops2='1'
