检查变量是否与多个值不同

var variable = "example";

if (variable !== "value1" && variable !== "value2" && variable !== "value3") {
  console.log("The variable is different from all the specified values.");
} else {
  console.log("The variable is equal to at least one of the specified values.");
}

variable = "example"

if variable not in ["value1", "value2", "value3"]:
    print("The variable is different from all the specified values.")
else:
    print("The variable is equal to at least one of the specified values.")

SELECT * FROM table WHERE variable NOT IN ('value1', 'value2', 'value3');
