在 sql 代码中使用 Like 运算符。语法错误答案

【问题标题】：Using Like operator in sql code. Syntax error在 sql 代码中使用 Like 运算符。语法错误

【问题描述】：

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。我写了一个代码，但代码给出了语法错误。请指教。

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;

【问题讨论】：

语法错误不是和&符号有关吗？在 TSQL 中，您可能应该使用“AND”运算符。

【解决方案1】：

在 Access（标记的）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] & "*"

这里缺少的是我永远记不起的 Access SQL 的复杂括号。

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

它仍然无法正常工作。它显示语法错误并突出显示 rcdt database.specification

【解决方案2】：

似乎你有很多 () 围绕连接元素

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)
   ...........

【讨论】：

还是不行..请看一下。 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;
RCDT 数据库的关闭也是错误的 .. asnwer 已更新

【解决方案3】：

MS Access 需要在 JOINs 周围加上括号：

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;
