DATEADD函數導致溢出

Question

我在寫一個StoredProcedure，我需要知道表中是否有最近10秒內更新的Resultset。 我的想法是：

SELECT @CNT = ba_sales_funnel_id FROM CRM7.BA_SALES_FUNNEL WHERE project_id = @project_id 
                  and sale_id = @sale_id 
                  and DATEDIFF(SECOND, updated, GETDATE()) < 10 

我收到以下錯誤代碼在這裏：

DateDiff函數導致溢出。分隔兩個日期/時間實例的日期部分數量太大。嘗試使用不精確的日期部分的datediff。

希望你能幫助我。

=======================================

解決方案：

  SELECT @CNT = ba_sales_funnel_id FROM CRM7.BA_SALES_FUNNEL WHERE project_id = @project_id 
                  and sale_id = @sale_id 
                  and DATEDIFF(YEAR, updated, GETDATE()) < 1 
                  and DATEDIFF(MONTH, updated, GETDATE()) < 1 
                  and DATEDIFF(DAY, updated, GETDATE()) < 1 
                  and DATEDIFF(SECOND, updated, GETDATE()) < 10 

OR

SELECT @CNT = ba_sales_funnel_id FROM CRM7.BA_SALES_FUNNEL WHERE project_id = @project_id 
                 and sale_id = @sale_id 
                 and updated >= DATEADD(second,-10,GETDATE())

試圖改變自己的SQL這樣的：

SELECT @CNT = ba_sales_funnel_id FROM CRM7.BA_SALES_FUNNEL WHERE project_id = @project_id 
                  and sale_id = @sale_id 
                  and updated >= DATEADD(second,-10,GETDATE())
