Question

我尝试对SalesForce Db执行左外连接，以从Product2表获取Id和ProductCode字段，并从关联（如果存在）PriceBookEntry获取一些字段。我也有PriceBook2，id ='01sd00000008iWpAAI'。以下是示例查询：

SELECT Id, ProductCode, 
(SELECT Id, PriceBook2Id, PriceBookEntry__r.Product2Id FROM PriceBookEntry__r 
WHERE PriceBook2Id='01sd00000008iWpAAI') 
FROM Product2 WHERE ProductCode IN 
('151','250','256','270','289')

返回给我的错误是：

INVALID_TYPE: PriceBookEntry__r.Product2Id FROM PriceBookEntry 
WHERE PriceBook2Id='01sd00000008iWpAAI') 
^ ERROR at Row:1:Column:89 
Didn't understand relationship 'PriceBookEntry__r' in FROM part of query call. 
If you are attempting to use a custom relationship, 
be sure to append the '__r' after the custom relationship name. 
Please reference your WSDL or the describe call for the appropriate names..

我为此查询尝试了几种变体，但没有成功。我在Product2表中有这些ProductCodes的行。

我想念那里？

我找到了解决方案：关键是表PriceBookEntry。它应该是复数（PriceBookEntries）。所以查询应该是：

SELECT Id, ProductCode, 
(SELECT Id, PriceBook2Id, Product2Id FROM PriceBookEntries
WHERE PriceBook2Id='01sd00000008iWpAAI') 
FROM Product2 WHERE ProductCode IN 
('151','250','256','270','289')

SalesForce的LEFT OUTER JOIN不起作用
