php变量用作mysqli列名语法错误

Question

这就是我认为这就是问题......

$sql1 = "SELECT `puntos_globales`, '$juego' 
         FROM `lista_jugadores` WHERE `id_jugador`='$noTop'";

这是错误消息：

错误：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near "blackOps2'='1' WHERE `id_jugador` = '10" at line 1

$ juego ..是一个包含列名的php变量;在这种情况下blackOps2。我不知道为什么在错误中说blackOps2'='1'??

Answer 1

从错误中看来你没有提供真正的查询，它看起来你有两个where子句

     blackOps2='1' WHERE `id_jugador` = '10"

尝试这样做

     WHERE `id_jugador` = '10' AND blackOps2='1'
