Question

我正在尝试加入四个表，我收到错误'加入表达式中的语法错误'

请在下面找到我目前正在尝试编写的查询

SELECT a.*,
switch(a.[Start Date] between b.[SEASON1START] and b.[SEASON1END],b.[LRA_S1_RT1_SGL],
a.[Start Date] between c.[SEASON1START] and c.[SEASON1END],c.[LRA_S1_RT1_SGL],
a.[Start Date] between d.[SEASON1START] and d.[SEASON1END],d.[LRA_S1_RT1_SGL]) as [Negotiated Rate Local],
switch(a.[Start Date] between b.[SEASON1START] and b.[SEASON1END],
b.[RATE_CURR],a.[Start Date] between c.[SEASON1START] and c.[SEASON1END],c.[RATE_CURR],
a.[Start Date] between d.[SEASON1START] and d.[SEASON1END],d.[RATE_CURR]) as [Negotiated Currency]
FROM ((([Q1001 - Split Transactions] a 
left join [2014 Negotiated Rate] b on (a.[RX_ID] = b.[PROPCODE] And YEAR(a.[Start Date] = 2014))
left join [2015 Negotiated Rate] c on (a.[RX_ID] = c.[PROPCODE] And YEAR(a.[Start Date] = 2015)) 
left join [2016 Negotiated Rate] d on (a.[RX_ID] = d.[PROPCODE] And YEAR(a.[Start Date] = 2016)) ;

Answer 1

MS Access不允许RewriteRule子句中的常量。解决方案？切换到更好的数据库。等一下。这不是一个选择。所以，救援的子查询：

on

Answer 2

您的原始查询应该有效。在MS Access中，您可以在ON子句中使用WHERE子句中的表达式（尽管仅在 SQL视图中的设计视图中无法查看复杂的表达式）。

具体来说，您没有正确包装YEAR()功能。请考虑以下调整：

FROM ((([Q1001 - Split Transactions] a 
left join [2014 Negotiated Rate] b 
      on (a.[RX_ID] = b.[PROPCODE] And YEAR(a.[Start Date]) = 2014))
left join [2015 Negotiated Rate] c 
      on (a.[RX_ID] = c.[PROPCODE] And YEAR(a.[Start Date]) = 2015)) 
left join [2016 Negotiated Rate] d 
      on (a.[RX_ID] = d.[PROPCODE] And YEAR(a.[Start Date]) = 2016));
