Question

我尝试使用表CITIES中的城市更新表STATES中的州首府。我想要两者，州名和城市名称都要参数化。

拥有此代码

UPDATE STATES
SET State_capital=DLookUp("ID","CITIES","City='Los Angeles'")
WHERE State_name=[Enter State Name:];

问题是城市名称未在DLookUp中参数化，Access不接受此更新形式：

UPDATE STATES
SET State_capital=(SELECT ID FROM CITIES WHERE City=[Insert city here])
WHERE State_name=[Enter State Name:];

解决方案是什么？谢谢！

此查询适用于Access 2010：

PARAMETERS [Enter City name:] Text(255), [Enter State name:] Text(255);
UPDATE STATES SET 
State_capital=DLookup("ID","CITIES","City='" & Replace([Enter City name:],"'","''") & "'")
WHERE State_name=[Enter State name:]

SQL中的参数化更新（Microsoft Access）
