'=' SSRS Report Builder 3.0 附近的语法不正确

Question

很抱歉，如果之前有人问过并回答过这个问题，但我无法找到解决我特定问题的答案。

我在尝试运行 ssrs 查询时收到以下消息，但我不确定如何更正它。通常，错误是指额外的空间或可以从复制和粘贴中提取的任何内容，但如果有的话我找不到它，我不确定还有什么问题。这是查询后跟的错误消息。任何帮助/cmets 将不胜感激

Answer 1

如果您使用的是早于 2012 年的 SQL 版本，请尝试更改：

,IIF(vTTSTMW_ChargeDetails.[Delivery Year]=@DeliveryYear, SUM(vTTSTMW_ChargeDetails.Charge),0) AS [Revenue Current Year]
,IIF(vTTSTMW_ChargeDetails.[Delivery Year]=@DeliveryYear-1, SUM(vTTSTMW_ChargeDetails.Charge),0) AS [Revenue Prior Year]

到这里：

,SUM(CASE WHEN vTTSTMW_ChargeDetails.[Delivery Year]=@DeliveryYear THEN vTTSTMW_ChargeDetails.Charge ELSE 0 END) AS [Revenue Current Year]
,SUM(CASE WHEN vTTSTMW_ChargeDetails.[Delivery Year]=@DeliveryYear-1 THEN vTTSTMW_ChargeDetails.Charge ELSE 0 END) AS [Revenue Prior Year]

编辑

并尝试改变这个：

@DeliveryYear-1

到这里：

CONVERT(nvarchar(7), CAST(@DeliveryYear AS int)-1)

Answer 2

您可能需要将聚合放在 IIF 语句之外，如下所示：

SELECT 
      company.cmp_name
    , commodity.cmd_code
    , commodity.cmd_name
    , SUM(
        IIF(
            vTTSTMW_ChargeDetails.[Delivery Year] = @DeliveryYear, 
            vTTSTMW_ChargeDetails.Charge, 
            0
            )
        ) AS [Revenue Current Year]
    , SUM(
        IIF(
            vTTSTMW_ChargeDetails.[Delivery Year] = @DeliveryYear - 1, 
            vTTSTMW_ChargeDetails.Charge, 
            0
            ) 
        ) AS [Revenue Prior Year]
FROM
    company
    LEFT OUTER JOIN vTTSTMW_ChargeDetails ON company.cmp_id = vTTSTMW_ChargeDetails.[Bill To ID]
    LEFT OUTER JOIN commodity ON vTTSTMW_ChargeDetails.[Order CMD Code] = commodity.cmd_code
GROUP BY
      company.cmp_name
    , commodity.cmd_code
    , commodity.cmd_name
