Question

我想在代码中使用4到5个表。但是在代码之间，我需要使用like运算符来使用contains属性。我已经编写了代码，但是代码给出了语法错误。请告知。

SELECT 
    [RCDT Database].FUNCTIONALITY, 
    [RCDT Database].SPECIFICATION, 
    [RCDT Database].[TEST NAME]
FROM SelectedClearingName 
INNER JOIN Clearing ON (SelectedClearngName.ClearingName=Clearing.ClearingName) 
INNER JOIN FunctionalityWiseClearing ON (Clearing.ClearingName=FunctionalityWiseClearing.Clearing) 
INNER JOIN SelectedValues ON (FunctionalityWiseClearing.Functionality=SelectedValues.ListBoxValues) 
INNER JOIN [RCDT Database] ON ([RCDT Database].FUNCTIONALITY Like "" & [SelectedValued.ListBocValues] & "" 
INNER JOIN SelectedPaytype ON ([RCDT Database].[PAY TYPE]=SelectedPaytype.PaytypeValue;

Answer 1

在Access（已标记）SQL中，它将是：

Like "*" & [Selectedvalues.ListBoxValues] & "*"

编辑：

将其简化为：

SELECT 
    [RCDT Database].FUNCTIONALITY, 
    [RCDT Database].SPECIFICATION, 
    [RCDT Database].[TEST NAME]
FROM 
    [RCDT Database],
    SelectedClearingName 
INNER JOIN 
    Clearing ON (SelectedClearngName.ClearingName=Clearing.ClearingName) 
INNER JOIN 
    SelectedValues ON (FunctionalityWiseClearing.Functionality = SelectedValues.ListBoxValues) 
INNER JOIN 
    FunctionalityWiseClearing ON (Clearing.ClearingName=FunctionalityWiseClearing.Clearing) 
INNER JOIN    
    SelectedPaytype ON ([RCDT Database].[PAY TYPE]=SelectedPaytype.PaytypeValue
WHERE
    [RCDT Database].FUNCTIONALITY Like "*" & [SelectedValued.ListBocValues] & "*"

这里缺少的是Access SQL令人费解的括号，我从没想过。

因此，删除Where子句，使用GUI设计器创建内部联接，然后添加Where子句。

似乎您必须在（）周围加入很多元素

SELECT 
    [RCDT Database].FUNCTIONALITY, 
    [RCDT Database].SPECIFICATION, 
    [RCDT Database].[TEST NAME]
FROM  SelectedClearingName 
    INNER JOIN Clearing ON (SelectedClearngName.ClearingName=Clearing.ClearingName)
    INNER JOIN FunctionalityWiseClearing ON (Clearing.ClearingName=FunctionalityWiseClearing.Clearing) 
    INNER JOIN SelectedValues ON (FunctionalityWiseClearing.Functionality=SelectedValues.ListBoxValues)
   ...........

MS Access需要在JOIN前后加上括号：

SELECT [RCDT Database].FUNCTIONALITY, [RCDT Database].SPECIFICATION, [RCDT Database].[TEST NAME]
FROM ((((SelectedClearingName INNER JOIN
         Clearing
         ON SelectedClearngName.ClearingName = Clearing.ClearingName
        ) INNER JOIN
        FunctionalityWiseClearing
        ON Clearing.ClearingName = FunctionalityWiseClearing.Clearing
       ) INNER JOIN
       SelectedValues
       ON FunctionalityWiseClearing.Functionality = SelectedValues.ListBoxValues
      ) INNER JOIN
      [RCDT Database]
      ON [RCDT Database].FUNCTIONALITY Like "" & [SelectedValued.ListBocValues] & "" 
     ) INNER JOIN
     SelectedPaytype
     ON ([RCDT Database].[PAY TYPE] = SelectedPaytype.PaytypeValue;

在SQL代码中使用Like运算符。语法错误
