我不断收到语法错误

*关键字“SELECT”附近的语法不正确。

')' 附近的语法不正确。*

当使用 where exists 子句时，我是否使用了正确的 where exists 格式。

SELECT 
   tblLoadMaster.Salesperson, tblLoadMaster.LoadID, LoadRate, 
   PayBetween1, Paybetween2, 
   tblLoadMaster.BillingID, OriginationCity, OriginationState, 
   DestinationCity, DestinationState 
FROM tblLoadMaster
WHERE EXISTS (SELECT tblCarrier.CompanyName, tblCarrier.CarrierID 
              FROM tblCarrier 
              WHERE tblLoadMaster.CarrierID = tblCarrier.CarrierID)
  AND EXISTS (SELECT tblCustomer.CompanyName, tblCustomer.Customerflag, tblCustomer.CustomerID, tblCustomer.AddressLine1, tblCustomer.City, tblCustomer.State, tblCustomer.Zipcode, tblCustomer.CompanyPhoneNumber, tblCustomer.CompanyFaxNumber, tblCustomer.SCAC 
              FROM tblCustomer 
              WHERE tblCustomer.CustomerID = tblLoadMaster.CustomerID )
  AND EXISTS(SELECT StopLocationID FROM tblLoadStop 
             WHERE tblLoadMaster.LoadID = tblLoadStop.LoadID) 
  AND EXIST(SELECT StopLocationCompanyName 
            FROM tblStoplocation 
            WHERE tblStopLocation.StoplocationID = tblLoadStop.StoplocationID 
              AND tblLoadMaster.Phase LIKE '%4%')  
ORDER BY 
    tblCarrier.CarrierID DESC;

更新

我改用INNER JOIN了语句，但仍然得到重复的行。该tblLoadStop表是我通过and获取stoplocation信息的查找表。该表包含两次stoplocation IDload IDtblLoadstopLOADID

LoadStopID(pk)   LoadID        StopLocationID
476          13521             67       
477          13521            106

然后中继器在表中显示该行两次，只有LoadID相同的行。

这是我的INNER JOIN声明；

SELECT  
   tblCarrier.CarrierID, tblLoadMaster.Salesperson, tblCustomer.CompanyName, 
   tblCarrier.CompanyName, tblCustomer.Customerflag, tblCustomer.CustomerID, 
   tblCustomer.AddressLine1, tblCustomer.City, tblCustomer.State, 
   tblCustomer.Zipcode, tblCustomer.CompanyPhoneNumber, 
   tblCustomer.CompanyFaxNumber, tblCustomer.SCAC, StopLocationCompanyName, 
   tblLoadMaster.LoadID,LoadRate,PayBetween1, Paybetween2 , tblLoadMaster.BillingID, 
   OriginationCity, OriginationState, DestinationCity, DestinationState 
FROM 
   tblLoadMaster 
INNER JOIN 
   tblCarrier On tblLoadMaster.CarrierID = tblCarrier.CarrierID 
INNER JOIN 
   tblCustomer ON tblCustomer.CustomerID = tblLoadMaster.CustomerID
INNER JOIN 
   tblLoadStop ON tblLoadMaster.LoadID = tblLoadStop.LoadID 
INNER JOIN 
   tblLkupCarrierLoad ON tblLkupCarrierLoad.CarrierID = tblCarrier.CarrierID 
INNER JOIN 
   tblStoplocation ON tblStopLocation.StoplocationID = tblLoadStop.StoplocationID  
WHERE 
   tblLoadMaster.Phase LIKE '%4%'  
ORDER BY 
   tblCarrier.CarrierID DESC;

也许是最后一个“EXISTS”中的错字被写成“EXIST”

SELECT tblLoadMaster.Salesperson,  tblLoadMaster.LoadID,LoadRate,PayBetween1, Paybetween2 , tblLoadMaster.BillingID, OriginationCity,OriginationState, DestinationCity, DestinationState 
FROM tblLoadMaster 
 WHERE EXISTS 
    (SELECT tblCarrier.CompanyName,tblCarrier.CarrierID FROM tblCarrier WHERE tblLoadMaster.CarrierID =tblCarrier.CarrierID )
 AND EXISTS 
  (SELECT tblCustomer.CompanyName, tblCustomer.Customerflag, tblCustomer.CustomerID, tblCustomer.AddressLine1, tblCustomer.City, tblCustomer.State, tblCustomeripcode, tblCustomer.CompanyPhoneNumber, tblCustomer.CompanyFaxNumber, tblCustomer.SCAC FROM tblCustomer WHERE tblCustomer.CustomerID=tblLoadMaster.CustomerID )
 AND EXISTS
    (SELECT StopLocationID FROM tblLoadStop WHERE tblLoadMaster.LoadID=tblLoadStop.LoadID) 
 AND EXISTS
  ( SELECT StopLocationCompanyName FROM tblStoplocation WHERE tblStopLocation.StoplocationID=tblLoadStop.StoplocationID AND  tblLoadMaster.Phase LIKE '%4%') 
ORDER BY tblCarrier.CarrierID DESC;

顺便说一句，我不确定您使用的是哪个数据库，但我更喜欢在存在子句上使用“从表中选择 1”。它似乎更具可读性，您马上就知道您只想知道是否有返回，而选择的列根本不重要

SELECT tblLoadMaster.Salesperson,  tblLoadMaster.LoadID,LoadRate,PayBetween1, Paybetween2 , tblLoadMaster.BillingID, OriginationCity,OriginationState, DestinationCity, DestinationState 
FROM tblLoadMaster 
 WHERE EXISTS 
    (SELECT 1 FROM tblCarrier WHERE tblLoadMaster.CarrierID =tblCarrier.CarrierID )
 AND EXISTS 
  (SELECT 1 FROM tblCustomer WHERE tblCustomer.CustomerID=tblLoadMaster.CustomerID )
 AND EXISTS
    (SELECT 1 FROM tblLoadStop WHERE tblLoadMaster.LoadID=tblLoadStop.LoadID) 
 AND EXISTS
  ( SELECT 1 FROM tblStoplocation WHERE tblStopLocation.StoplocationID=tblLoadStop.StoplocationID AND  tblLoadMaster.Phase LIKE '%4%') 
ORDER BY tblCarrier.CarrierID DESC;

是不是更漂亮了点？

您在下面说 EXIST，而不是 EXISTS：（​​更改以粗体显示）

"SELECT 
     tblLoadMaster.Salesperson,  tblLoadMaster.LoadID,
     LoadRate, PayBetween1, Paybetween2 , tblLoadMaster.BillingID,

   tblLoadMaster "+
"WHERE 
     EXISTS (SELECT

             FROM

             WHERE 
                    tblLoadMaster.CarrierID =tblCarrier.CarrierID )" +
 "AND
