VS2012 BIDS之Reporting Service/SSRS 项目2--开发过程问题总结(全)

由刚开始的接触到现在做出来一个基本完整的SSRS的项目，学到了比较多的知识，和大家共享。

上一篇学习总结可能有些问题，一起修正和总结。

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

首先，使用BIDS开发SSRS过程中，感觉还是不太灵活，比如参数的控件《暂且说为“控件”》只能是一行排两个，而且根据参数多值还是单值的类型，控件长度不可调整，导致看起来比较不舒服。

群好友建议：

可以结合winform与C#系统集成，或者Webform弄一个.aspx页面，在.aspx页面上放置各种参数控件，然后传给SSRS报表,aspx页面是自己写的，可以随便改。还可以通过调用dll,弹出友好的提示框等。但是如果这样做，可能要用附属于vs里面的 ReportViewer控制项，设计过程中也会有一定的缺点《后续学习》

以下是效果图：

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

现在开始总结：

Q1.上篇讲到共享数据集采用：调用存储过程的形式，但是存错过程的参数（多值参数）会有了一些讲究。因为SSRS传多值参数是以逗号分割的，比如多选’A,B,C‘需要自己分割为'A','B','C'才可用。

Solution:

参考：http://blog.sina.com.cn/s/blog_5ef7acf50100ri6p.html

参考利用Join函数的时候感觉不是很好用，可能是我用错了，另一篇，没研究（以下是链接），我直接用了第二种自定义表值函数的方法来得到分割后的字段值，然后取用。

以下是自定义分割函数代码：

在存储过程中调用的时候需要在WHERE参数条件后添加：

AND (D.PROVINCE_CODE IN(SELECT value from [dbo].[fnSplitStr](@PROVINCE ,','))OR('ALL'=@PROVINCE))

Q2：需要控制查询期间，并提示信息！避免数据量过大导致浏览器负荷过载崩溃。（虽然经过Procedure优化调用后，查询速度明显加快）

因为以前写Winform的经验是，调用存储过程，如果存储过程raiserror的话，在程序catch时，formshow直接弹出提示框即可。所以在procedure中判断查询时间期间，发现这样的话在SSRS报表处理期间就会出错！所以不可行！

Solution:

在RDL页眉处添加文本框，设置表达式，用以提示信息。在procedure中用IF语句，条件不符合，直接return跳出存储过程，查询结果直接是'Return Value'=0即查询结果为空就好了(见以上Procedure代码)。

以下是表达式：

=IIf(DateDiff(DateInterval.Day,Parameters!STARTDATE.Value,Parameters!ENDDATE.Value)>=365,"查询日期期间超出一年范围！","查询日期期间为一年内OK!")

Q3：客户要求参数选择需要对应归总显示，如下需要ChannelType字段，并且只显示'NC,3C,TC',但是WHERE筛选的时候还是需要对应。

select distinct A.CHANNEL_TYPE_CODE,
CASE A.CHANNEL_TYPE_CODE WHEN 'Y3C'THEN'3C'WHEN'YKA'THEN 'TC'WHEN'YTC'THEN 'TC'ELSE 'NC'END AS ChannelType
from CB_ST_CHANNEL A

View Code

Solution:

参数只可选'NC,3C,TC'，先查询筛选除ChannelType字段之外的数据集 INTO #TEMP临时表（并转换ChannelTyep值），然后选择#TEMP的记录筛选 ChannelTyep（详见Procedure）

Q4:参数默认为ALL,并且位于下拉框的第一个。参数数据集查询语句经过SQL定义排序即可。如：Brand品牌参数。

1 SELECT DISTINCT BRAND, IDENTITY(INT,1,1)AS BRAND_CODE INTO #TEMP FROM CB_PRODUCT
2 WHERE BRAND IS NOT NULL
3 
4 SELECT 'ALL'AS BRAND,000 as BRAND_CODE
5 UNION 
6 SELECT * FROM #TEMP 
7 ORDER BY BRAND_CODE ASC
8 
9 DROP TABLE #TEMP

Q4：一页内下拉Scroll Bar固定冻结表头,每一页重复显示表头。

旧版矩阵/表控件属性的"RpeatHeaderOnNewPage"或者是"RpeatFooterOnNewPage"属性神马的就不要想了，书中说不好用，亲测也不好用。以下解决方案绝对好用，但是要认真按步骤做。

Solution：

每页重复表头：

STEPS：列组右角点击"高级模式" -> 点击行组（静态）<在详细信息上方> -> 看属性窗口"Tablix 成员"属性 -> 修改"RepeateOnNewPage"值为"True"，Ok!Bingo!

页内冻结表头：

STEPS：列组右角点击"高级模式" -> 点击行组（静态）<在详细信息上方> -> 看属性窗口"Tablix 成员"属性 -> 修改"FixedData"值以及"KeepTogether"的值为"True"，Ok!Bingo!

以下是部署到sharepoint之后的效果图：

Q5：item_code（料号）参数可为空，即不传此参数时，直接不筛选此条件：

Solution:

将ITEM_CODE参数属性设置为：可为null值，Procedure里加一句判断即可：

1 IF(@ITEM_CODE IS NULL)
2     BEGIN
3     SET  @ITEM_CODE ='ALL'
4     END
5 ELSE
6     BEGIN SET @ITEM_CODE=@ITEM_CODE 
7     END

Q6：SSRS导出到excel之后出现单元格合并/隐藏现象

Solution:主要是要注意页眉页脚控件Width/Height设置（对齐），SSRS导出到Excel是以pt来计量，根据转换公式：1in = 2.54cm = 25.4 mm = 72pt = 6pc 来转换。参考：http://blog.csdn.net/hery2002/article/details/45697777

一般Width设置为保留两位小数均可（单位in/cm均可）。excel默认单元格Width：72pt(1in)/Height:18pt(0.25in)

调整后：

结果图：明朗了很多！
