WHERE中的SSRS参数

Question

I thought this would be really simple but I can't get a way that works.

Basically I would like to make the report search by the entered parameters, IE in the WHERE clause.

For example, parameters in the below would be @ColumnName and @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)%'

This must be possible? Many thanks.

Answer 1

I don't always like to encourage the use of dynamic SQL, but the following will do what you are trying to accomplish.

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)

The following is how I would really do this, but you may have reasons for not wanting to do this. Up to you.

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 + '%')...

Good luck!

Answer 2

Try this:

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 + '%'

Note your parameter must be text type.

Let me know if this helps.
