Mysql结合更新查询

Question

mysql_query("UPDATE rekod SET ns = '1' WHERE zone ='255' AND data ='$id1'");
mysql_query("UPDATE rekod SET ns = '1' WHERE zone ='255' AND data ='$id2'");

而不是两次运行查询是否有一种方法可以只更新一次？差异只是数据值。请帮帮我？

Answer 1

"UPDATE rekod SET ns = '1' WHERE zone ='255' AND data IN('$id1','$id2')"

或

"UPDATE rekod SET ns = '1' WHERE zone ='255' AND (data='$id1' OR data='$id2')"

Answer 2

你可以像这样使用OR语句：

mysql_query("UPDATE rekod SET ns = '1' WHERE zone ='255' AND (data ='$id1' OR data = '$id2')");
