SQL查询不执行correcly（其中）

Question

我有一个小问题，执行SQL查询。

在我的BD我有3列（experimentID，的applicationID，意图）

我想与experimentID = 3

我询问一些具体的意图是：

SELECT experimentID, applicationID, intent 
from intents 
WHERE experimentID = 3 AND intent='android.intent.action.AIRPLANE_MODE' OR intent='android.intent.action.ALL_APPS' OR intent='android.intent.action.ANSWER' OR intent='android.intent.action.APPLICATION_PREFERENCES' OR intent='android.intent.action.APPLICATION_RESTRICTIONS_CHANGED' OR intent='android.intent.action.ACTION_EXTERNAL_APPLICATIONS_AVAILABLE' OR intent='android.intent.action.APP_ERROR' OR intent='android.intent.action.ASSIST' OR intent='android.intent.action.PHONE_STATE' OR intent='android.intent.action.ATTACH_DATA' OR intent='android.intent.ACTION_SCREEN_OFF' OR intent='android.intent.action.BATTERY_CHANGED' OR intent='android.intent.action.BATTERY_CHANGED_ACTION' OR intent='android.intent.action.BATTERY_LOW' OR intent='android.service.wallpaper.WallpaperService' OR intent='android.intent.action.QUICKBOOT_POWERON' OR intent='android.net.conn.CONNECTIVITY_CHANGE' OR intent='android.intent.action.BATTERY_OKAY' OR intent='android.intent.action.START_SMS_SERVICE' OR intent='android.app.action.ACTION_DEVICE_ADMIN_DISABLE_REQUESTED' OR intent='android.intent.action.BOOT_COMPLETED' OR intent='android.intent.action.BUG_REPORT' OR intent='android.intent.action.CALL' OR intent='android.intent.action.RESPOND_VIA_MESSAGE' OR intent='android.intent.action.CALL_BUTTON' OR intent='android.intent.action.CAMERA_BUTTON' OR intent='android.intent.action.CARRIER_SETUP'; 

问题是我也得到其他experimentID ...（不仅实验ID = 3）

我认为这是因为查询中的OR，但如何我可以查询得到experiementID = 3吗？问题显然在WHERE

感谢您的帮助！

Answer 1

括号可以解决问题。但更好的方法是in：

SELECT experimentID, applicationID, intent 
FROM intents 
WHERE experimentID = 3 AND 
     intent IN ('android.intent.action.AIRPLANE_MODE', 
       . . . 
       'android.intent.action.CARRIER_SETUP' 
       ); 

Answer 2

SELECT experimentID, applicationID, intent 
from intents 
WHERE experimentID = 3 
((AND intent='android.intent.action.AIRPLANE_MODE')(OR intent='android.intent.action.ALL_APPS' OR intent='android.intent.action.ANSWER' OR intent='android.intent.action.APPLICATION_PREFERENCES' OR intent='android.intent.action.APPLICATION_RESTRICTIONS_CHANGED' OR intent='android.intent.action.ACTION_EXTERNAL_APPLICATIONS_AVAILABLE' OR intent='android.intent.action.APP_ERROR' OR intent='android.intent.action.ASSIST' OR intent='android.intent.action.PHONE_STATE' OR intent='android.intent.action.ATTACH_DATA' OR intent='android.intent.ACTION_SCREEN_OFF' OR intent='android.intent.action.BATTERY_CHANGED' OR intent='android.intent.action.BATTERY_CHANGED_ACTION' OR intent='android.intent.action.BATTERY_LOW' OR intent='android.service.wallpaper.WallpaperService' OR intent='android.intent.action.QUICKBOOT_POWERON' OR intent='android.net.conn.CONNECTIVITY_CHANGE' OR intent='android.intent.action.BATTERY_OKAY' OR intent='android.intent.action.START_SMS_SERVICE' OR intent='android.app.action.ACTION_DEVICE_ADMIN_DISABLE_REQUESTED' OR intent='android.intent.action.BOOT_COMPLETED' OR intent='android.intent.action.BUG_REPORT' OR intent='android.intent.action.CALL' OR intent='android.intent.action.RESPOND_VIA_MESSAGE' OR intent='android.intent.action.CALL_BUTTON' OR intent='android.intent.action.CAMERA_BUTTON' OR intent='android.intent.action.CARRIER_SETUP'));
