Question

我需要使用日期参数设计报告（需要采用英国日期格式）

Original date format: 2007-11-30 00:00:00.000

So, I am using CONVERT(Date, Start_Date, 103): 2007-11-30 in my query.

Data in Query:

Start_Date            End_Date                Type
---------------------------------------------------------------      NULL                  2016-01-23                 3 Month 
2009-08-11            2009-07-27                 3 Month  
NULL                  2015-10-13                 3 Month
NULL                  2016-02-16                 3 Month
NULL                  2015-12-28                 3 Month

现在在设计报告时我正在使用这个数据集：

主数据集查询：

SELECT Col1, Col2, Start_Date, Target_Date, Col3
FROM  Table
WHERE        (Col1 IN (@Param1))
AND (Col2IN (@Param2)) 
AND (Start_Date IN (@Start_Date)) AND (Target_Date IN (@Target_Date))

Now, When I run this report for Start_Date = 2009-08-11  and End_Date = 2009-07-27  and Type= 3 Month I get detailed data in report. 

However, When I select Start_Date = NULL   and End_Date = 2016-02-16   and Type= 3 Month my report appears blank. I checked dataset and that too returns all values as NULL.

你能否建议/帮助解决这个问题？

Answer 1

Start_Date = NULL

无法使用。您需要使用

Start_Date IS NULL

或

ISNULL(Start_Date, 0) = 0

这样的事情：

SELECT Col1, Col2, Start_Date, Target_Date, Col3
FROM [Table]
WHERE Col1 IN (@Param1)
      AND Col2 IN (@Param2)
      AND ISNULL(Start_Date, 0) IN (ISNULL(@Start_Date, 0))
      AND ISNULL(Target_Date, 0) IN (ISNULL(@Target_Date, 0));

参数未在SSRS报告中拾取NULL值显示为空白
