Question

我根据业务规则要求更改报表上的预定交货日期。以下是DDL：

1）如果作业有批号，则预定发货日期将是下一个星期一到请求的交货日期。例如，如果作业的请求交货日期为2015-07-29，并且它还有批号，那么预定发货日期将为2015-08-03。

2）如果作业没有批号，则预定发货日期将是请求交货日期之前的星期一。例如，如果作业J012347的请求交货日期为2015-08-04并且没有批号，那么预定发货日期将是2015-08-04之前的星期一。

同样，如果请求的交付日期是2015-08-07且没有批号，则预定交付日期为2015-08-03。

我们可以做到这一点吗？我很感激任何帮助。

希望这有帮助

这是DDL：

DECLARE @Date datetime;
SET @Date = GETDATE();

DECLARE @TEST_DATA TABLE

    DT_ID INT       IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED

   ,JobStatus       CHAR(1)       NOT NULL
   ,ExpectedDate    VARCHAR(10)   NOT NULL
   ,LastShippedDate VARCHAR(10)       NULL
   ,BatchNumber VARCHAR(10)         NULL
);

INSERT INTO @TEST_DATA (JobStatus, JobNumber,ExpectedDate,LastShippedDate, BatchNumber)

所以你试图找到＆＃34;下周一＆＃34;如果没有批次，并且请求日期前一个星期一有一个：

Select Case when BatchNumber is not null then  
                case when datepart(dw,J.ExpectedDate) > 1 then DATEADD(dd,9-DATEPART(dw,J.ExpectedDate),J.ExpectedDate)
                    else DATEADD(dd,1,J.ExpectedDate) end 
        Else dateadd(ww,-2, case when datepart(dw,J.ExpectedDate) > 1 then DATEADD(dd,9-DATEPART(dw,J.ExpectedDate),J.ExpectedDate)
                else DATEADD(dd,1,J.ExpectedDate) end) end AS [Scheduled Ship Date]


FROM @TEST_DATA AS J

T-sql有助于在SSRS报告上切换日期
