WHERE中的SSRS參數

Question

我認為這很簡單，但我無法找到一種有效的方法。

基本上我想通過輸入的參數，WHERE子句中的IE來進行報告搜索。

例如，下面的參數是@ColumnName和@SearchTerm

SELECT
OITM.[ItemCode] AS [Item Code],
OITM.[ItemName] AS [Item Name],
OITM.[FrgnName] AS [Merchandise Type],
OITM.[OnHand] AS [In Stock],
OITM.[IsCommited] AS [Customer Reserved], 
OITM.[Onorder] AS [On Order],
OITW.[AvgPrice] AS [Cost]

FROM OITW
 INNER JOIN OITM ON OITM.[ItemCode] = OITW.[ItemCode]

WHERE
OITM.(@ColumnName) LIKE '%(@SearchTerm)%'

這一定是可能的嗎？ 非常感謝。

我並不總是喜歡鼓勵使用動態SQL，但以下內容將完成您要完成的任務。

DECLARE @ColumnName varchar(10) = 'ItemName', @SearchTerm varchar(5) = 'pat', @sql varchar(1000) = ''

SELECT @sql = 'SELECT
OITM.[ItemCode] AS [Item Code],
OITM.[ItemName] AS [Item Name],
OITM.[FrgnName] AS [Merchandise Type],
OITM.[OnHand] AS [In Stock],
OITM.[IsCommited] AS [Customer Reserved], 
OITM.[Onorder] AS [On Order],
OITW.[AvgPrice] AS [Cost]

FROM OITW
 INNER JOIN OITM ON OITM.[ItemCode] = OITW.[ItemCode]

WHERE OITM.' + @ColumnName + ' LIKE ''%' + @SearchTerm + '%'''

EXEC (@sql)

以下是我如何真正做到這一點，但你可能有理由不想這樣做。 由你決定。

SELECT
OITM.[ItemCode] AS [Item Code],
OITM.[ItemName] AS [Item Name],
OITM.[FrgnName] AS [Merchandise Type],
OITM.[OnHand] AS [In Stock],
OITM.[IsCommited] AS [Customer Reserved], 
OITM.[Onorder] AS [On Order],
OITW.[AvgPrice] AS [Cost]

FROM OITW
 INNER JOIN OITM ON OITM.[ItemCode] = OITW.[ItemCode]

WHERE (OITM.ItemName LIKE '%' + @SearchTerm + '%'
    OR OITM.FrgnName LIKE '%' + @SearchTerm + '%')...

祝好運！

Answer 2

嘗試這個：

SELECT
OITM.[ItemCode] AS [Item Code],
OITM.[ItemName] AS [Item Name],
OITM.[FrgnName] AS [Merchandise Type],
OITM.[OnHand] AS [In Stock],
OITM.[IsCommited] AS [Customer Reserved], 
OITM.[Onorder] AS [On Order],
OITW.[AvgPrice] AS [Cost]

FROM OITW
 INNER JOIN OITM ON OITM.[ItemCode] = OITW.[ItemCode]

WHERE
OITM.(@ColumnName) LIKE '%' + @SearchTerm + '%'

請注意，您的參數必須是文本類型。

如果這有幫助，請告訴我。
