轉換失敗時轉換爲nvarchar成int

-2

我收到上述錯誤誰能請幫助什麼是代碼中的問題...轉換失敗時轉換爲nvarchar成int

P.YKey BETWEEN YEAR('''+ CONVERT(VARCHAR(50), @BDate, 103) +''') 
      AND YEAR('''+ CONVERT(VARCHAR(50), @eDate, 103) +''') 
    AND P.DCreation BETWEEN '''+ CONVERT(VARCHAR(50), @BDate, 103) +''' 
         AND '''+ CONVERT(VARCHAR(50), @eDate, 103) +''''

什麼是@BDate，@eDate的類型？

更新：由於兩個變量的類型是DATETIME，轉換不是必需的。

P.YKey BETWEEN YEAR(@BDate) 
      AND YEAR(@eDate) 
    AND P.DCreation BETWEEN @BDate 
         AND @eDate

DateTime @zhang – Rashi

，因爲它似乎是你有興趣的創建日期而已，還不是時候，我也投了日期時間日期。所以假設DCreation也是日期時間：

P.YKey BETWEEN YEAR(@BDate) 
      AND YEAR(@eDate) 
    AND cast(P.DCreation as date) BETWEEN cast(@BDate as date) 
           AND cast(@eDate as date)
