MySQL查询在Navicat中工作，但在其他地方生成MySQL语法错误

大家好，提前谢谢你们的帮助。我很沮丧，因为我正在编写相对较长的sql查询，至少对于像我这样的n00b来说，它在NaviCat中工作得非常好。然后，我将它们导入到dreamweaver sql编辑器中，在那里我正在设计我的站点，它们会返回

>   MySQL Error#: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 2 

我将发布其中一个问题，希望有人能指出我做错了什么

 SELECT (SELECT COUNT(GA_Potential.Potential_ID)
FROM GA_Potential
WHERE GA_Potential.Character_ID=14)+  (SELECT COUNT(GA_PurchasedPotential.PurchasedPotential_ID)From GA_PurchasedPotential Where GA_PurchasedPotential.Member_ID=2)+ (SELECT GA_Characters.StartPotential From GA_Characters WHERE GA_Characters.Character_ID =14)+ (SELECT FLOOR(iot_ActingPoints.Acting_Points/10) From iot_ActingPoints WHERE iot_ActingPoints.Member_ID=2)- (SELECT SUM(GA_AttributePoints.Determination_Points) FROM GA_AttributePoints WHERE GA_AttributePoints.Character_ID=14)- (SELECT SUM(GA_AttributePoints.Dexterity_Points) FROM GA_AttributePoints WHERE GA_AttributePoints.Character_ID=14)- (SELECT SUM(GA_AttributePoints.Productivity_Points) FROM GA_AttributePoints WHERE GA_AttributePoints.Character_ID=14)- (SELECT SUM(GA_AttributePoints.Sophistication_Points) FROM GA_AttributePoints WHERE GA_AttributePoints.Character_ID=14)- (SELECT SUM(GA_AttributePoints.Strength_Points) FROM GA_AttributePoints WHERE GA_AttributePoints.Character_ID=14)- (SELECT IFNULL(SUM(GA_CasteAbilitiesForList.Potential_Cost),0) FROM GA_CasteAbilitiesForList,GA_LearnedAblities WHERE GA_CasteAbilitiesForList.Ability_ID=GA_LearnedAblities.Ability_ID AND GA_LearnedAblities.Character_ID=14)- (SELECT IFNULL(SUM(GA_ProfAbilitiesForList.Potential_Cost),0) FROM GA_ProfAbilitiesForList,GA_LearnedAblities WHERE GA_ProfAbilitiesForList.Ability_ID=GA_LearnedAblities.Ability_ID AND GA_LearnedAblities.Character_ID=14) AS TOTAL

这正好生成我想要的NaviCat中的数字

编辑：我去掉了NaviCat自动输入的所有单引号，但仍然得到相同的错误

提前谢谢

只是一个臀部镜头：也许你需要在所有子选区周围使用括号，比如

SELECT 
((SELECT COUNT(`GA_Potential`.`Potential_ID`) From`GA_Potential` WHERE`GA_Potential`.`Character_ID`=14)+ 
(SELECT COUNT(`GA_PurchasedPotential`.`PurchasedPotential_ID`)From`GA_PurchasedPotential` Where`GA_PurchasedPotential`.`Member_ID`=2)+
(SELECT `GA_Characters`.`StartPotential` From `GA_Characters` WHERE `GA_Characters`.`Character_ID` =14)+
(SELECT FLOOR(`iot_ActingPoints`.`Acting_Points`/10) From `iot_ActingPoints` WHERE `iot_ActingPoints`.`Member_ID`=2)-
(SELECT SUM(`GA_AttributePoints`.`Determination_Points`) FROM `GA_AttributePoints` WHERE `GA_AttributePoints`.`Character_ID`=14)-
(SELECT SUM(`GA_AttributePoints`.`Dexterity_Points`) FROM `GA_AttributePoints` WHERE `GA_AttributePoints`.`Character_ID`=14)-
(SELECT SUM(`GA_AttributePoints`.`Productivity_Points`) FROM `GA_AttributePoints` WHERE `GA_AttributePoints`.`Character_ID`=14)-
(SELECT SUM(`GA_AttributePoints`.`Sophistication_Points`) FROM `GA_AttributePoints` WHERE `GA_AttributePoints`.`Character_ID`=14)-
(SELECT SUM(`GA_AttributePoints`.`Strength_Points`) FROM `GA_AttributePoints` WHERE `GA_AttributePoints`.`Character_ID`=14)-
(SELECT IFNULL(SUM(`GA_CasteAbilitiesForList`.`Potential_Cost`),0) FROM `GA_CasteAbilitiesForList`,`GA_LearnedAblities` WHERE `GA_CasteAbilitiesForList`.`Ability_ID`=`GA_LearnedAblities`.`Ability_ID` AND `GA_LearnedAblities`.`Character_ID`=14)-
(SELECT IFNULL(SUM(`GA_ProfAbilitiesForList`.`Potential_Cost`),0) FROM `GA_ProfAbilitiesForList`,`GA_LearnedAblities` WHERE `GA_ProfAbilitiesForList`.`Ability_ID`=`GA_LearnedAblities`.`Ability_ID` AND `GA_LearnedAblities`.`Character_ID`=14))
AS total

另外：错误消息是否真的在附近结束？

也有同样的问题-将此信息留给遇到此问题的其他人：

Dreamweaver不喜欢SQL中的多个SELECT语句。我能够重新处理查询，使其不需要多个SELECT语句，错误消失了

作为补充说明，我认为这是附加说明，但它们似乎可以与其他函数配合使用。

错误消息在它变得有趣的地方被完全切断！对不起，汤姆！我不知道为什么我认为这不相关。下面是完整的消息：MySQL错误：1064您的SQL语法有错误；检查与MySQL服务器版本相对应的手册，以获得在第行附近使用的正确语法2@user1262890-而不是试图解决整个问题。如果您仅使用第一个选项进行尝试，会发生什么情况？ie选择从GA_Potential中选择COUNTGA_Potential.Potential_ID，其中GA_Potential.Character_ID=14作为总数，如果有效，则添加第二个。有变化吗？您还可以研究是否可以使用CASE重写为一个、两个或三个较小的查询，这样会更具可读性，而且性能可能也更好；我一直在尝试这个查询的每个可能的迭代，只使用了前几个部分。从GA_Potential中选择SELECT COUNTGA_Potential.Potential_ID，其中GA_Potential.Character_ID=14+作为总返回MySQL错误：1064您的SQL语法有错误；查看与MySQL服务器版本对应的手册，以了解第2行附近要使用的正确语法。当然，如果您删除了初始的SELECT，查询就会工作，但是当您尝试对它们求和时，查询返回的数字是错误的。我也不知道如何使用CASE。你能给我举个例子吗？带括号的查询在Navicat中仍然有效，当我在Dreamweaver中测试它时，它会在我尝试使用数据时生成错误。我修改了我以前的帖子，把剩下的错误也包括进去了。很抱歉。
