尝试在两个过滤表之间执行 SQL 连接

Question

我正在尝试加入两个表，但对这两个表都应用了过滤器。例如。过滤左表，然后与右表的过滤版本连接，保留左表。

我的查询如下：

SELECT REP_Exposure_secured.DeliveryRegion, REP_Exposure_secured.DeliveryCountry, 
REP_Exposure_secured.EngagementCompanyCode, REP_Exposure_secured.EngagementId, 
REP_Exposure_secured.Engagement, REP_Exposure_secured.EngagementType,
REP_Exposure_secured.EngagementStatus, REP_Exposure_secured.EngagementPartner, 
REP_Exposure_secured.EngagementPartnerID, REP_Exposure_secured.EngagementManager, 
REP_Exposure_secured.ServiceLine, REP_Exposure_secured.SubServiceLine, 
REP_Exposure_secured.Competency, REP_Exposure_secured.ServiceOffering, 
REP_Exposure_secured.EngagementServiceCode, REP_Exposure_secured.EngagementService,
REP_Exposure_secured.EngagementLastTimeChargedDate, REP_Exposure_secured.EngagementCreationDate, 
REP_Exposure_secured.Account, REP_Exposure_secured.UltimateDunsNumber, 
REP_Exposure_secured.Client, REP_Exposure_secured.ClientID,
REP_Exposure_secured.AR_0_30, REP_Exposure_secured.AR_31_60, 
REP_Exposure_secured.AR_61_90, REP_Exposure_secured.AR_91_120, 
REP_Exposure_secured.AR_121_150, REP_Exposure_secured.AR_151_179, 
REP_Exposure_secured.AR_180_365, REP_Exposure_secured.AR_Above_365,
REP_Exposure_secured.MTD_TER, REP_Exposure_secured.MTD_BilledAmt, 
REP_Exposure_secured.MTD_CollectedAmt, REP_Exposure_secured.UnbilledInvAging30Amt, 
REP_Exposure_secured.UnbilledInvAging60Amt, REP_Exposure_secured.UnbilledInvAging90Amt,
REP_Exposure_secured.UnbilledInvAging150Amt, REP_Exposure_secured.UnbilledInvAging180Amt, 
REP_Exposure_secured.UnbilledInvAging365Amt, REP_Exposure_secured.UnbilledInvAging365PlusAmt, 
REP_FTEReport_secured.GPN, REP_FTEReport_secured.Country AS FTE_Country,
REP_FTEReport_secured.Country AS FTE_Country.EmployeeName AS FTE_Name

FROM Reporting.REP_Exposure_secured

LEFT JOIN REP_FTEReport_secured 
ON REP_Exposure_secured.EngagementPartnerID = REP_FTEReport_secured.GUI

WHERE (REP_Exposure_secured.DeliveryCountry IN ('Cambodia', 'Singapore', 'Malaysia', 'Indonesia',
'Guam', 'Laos', 'Maldives', 'Myanmar', 'Philippines', 'Sri Lanka', 'Thailand', 'Vietnam')
OR REP_Exposure_secured.DeliveryCountry LIKE 'Brunei Daruss%')
AND REP_Exposure_secured.SubServiceLine='Forensics'
AND REP_Exposure_secured.EngagementType LIKE 'External%'
AND REP_Exposure_secured.Currency='USD'
AND REP_FTEReport_secured.AccountingCycleDate IN
    (
        SELECT
            DISTINCT
            MAX(AccountingCycleDate)
        FROM
            REP_FTEReport_secured
            )
AND REP_FTEReport_secured.Country IN ('Brunei', 'Cambodia', 'Guam', 'Indonesia', 'Lao', 'Malaysia', 'Maldives',
'Myanmar', 'Philippines', 'Singapore', 'Sri Lanka', 'Thailand', 'Vietnam')
AND REP_FTEReport_secured.SubServiceLine='Forensics'
AND REP_FTEReport_secured.RankName IN ('Partner', 'Director', 'Executive Director');

这会返回以下错误：

: ('42000', "[42000] [Microsoft][ODBC SQL Server Driver][SQL Server]'.' 附近的语法不正确。(102) (SQLExecDirectW); [42000] [Microsoft][ODBC SQL Server驱动程序][SQL Server]关键字'AND'附近的语法不正确。(156)")

对我做错的任何帮助将不胜感激！

Answer 1

我认为您的问题在于这一行，即您的 select 子句中的最后一个字段。

REP_FTEReport_secured.Country AS FTE_Country.EmployeeName AS FTE_Name

它有 2 个别名和 2 个dots

混淆在最后两行

REP_FTEReport_secured.GPN, REP_FTEReport_secured.Country AS FTE_Country,
REP_FTEReport_secured.Country AS FTE_Country.EmployeeName AS FTE_Name

首先让它们更具可读性

REP_FTEReport_secured.GPN, 
REP_FTEReport_secured.Country AS FTE_Country,
REP_FTEReport_secured.Country AS FTE_Country.EmployeeName AS FTE_Name

现在您可以看到最后有问题。
你可能需要这个

REP_FTEReport_secured.GPN, 
REP_FTEReport_secured.Country AS FTE_Country,
REP_FTEReport_secured.EmployeeName AS FTE_Name

如您所见，只要使查询更具可读性，在这种情况下，每行只放置一个字段，而不是 2 个，错误就会立即可见
