Question

我正在写一个StoredProcedure，我需要知道表中是否有一个在过去10秒内更新过的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

我在这里得到以下错误代码：

datediff函数导致溢出。分隔两个日期/时间实例的日期部分数量太大。尝试使用具有不太精确的日期部分的datediff。

希望你能帮助我。

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

解决方案：

            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())

Answer 1

尝试将SQL更改为：

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())

DATEADD函数导致溢出
