Mysql組合更新查詢

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'"); 

而不是兩次運行查詢是否有一種方法可以只更新一次？只有數據值有區別。請幫幫我？

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

您可以使用OR語句，像這樣：

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