SSRS report failing to display dataset string

SSRS report failing to display dataset string# Database - 数据库

Hi,
I am working on a SSRS report from a store procedure I created.
The returned the dataset is showing in the picture
I create a dataset using tableadapter. I can preview the dataset without any
issue (in pic2)
Later I bind the dataset using objectDataSource, and select the datasource
in the rdlc file.
I drage and drop the values from the field to the table.
When I run the result, the first two columns display values correctly.
However, the rest columns all return empty string.
any idea why?

are you using a report wizard?
look at the report in design view and make sure the fields are setup
correctly.

yes, I was. the fields are directly referenced. I suspect SSRS has issue
with store procedures that do table variable manipulation.

no, SSRS doesn't care what you do in the SP
you have Visual Studio (or Business Intelligent Studio if you installed it
with SQL server disk)? check the report in design view.

thanks for responding. I use VS to design the rdlc file. It's was a straight
Fields!Stmt_Created_Date.Value drop in textbox. The field of "Group_Code"
and "Group_Member_Code" can be displayed without any problem but not for the
rest.
I did some research. One person raised the similar issue like mine. His
storeprocedure created a table variable and used cursor to combine different
rows into one row then put into the table variable and select the result as
the return set. That's very much like mine and he can not display all of
his dataset either, only part of them.
I suspect SSRS has some issue with returning values from dataset created
from store procedures like this. I resolved my problem by creating a
physical table instead of a table variable or temptable in the database and
insert value into that physical table then return the dataset. This works.

不要用RESULT DATASET，放到TEMP TABLE里去

先用SP把TABLE建好，填充好，最后SSRS显示一下TABLE就可以了，避免弄一个复杂的
JOIN QUERY去显示。

that was what I did. I created a table variable and just inserted values.
Later I replaced the table variable with temp table but no luck.
Below is my store procedure.
ALTER PROCEDURE [dbo].[SP_REPORT_GET_STATUS_DATES]

@Statement_Month TINYINT

你这个SP写得够烂的，怎么这么多的变量，还那么多CURSOR，难怪会出问题。多搞几个
TEMPTABLE也别用CURSOR，否则容易出错，时间比较用DATETIME，不要倒成VARCHAR去比
，容易出错。就是出个REPORT么，还CATCH什么。

u*e2011-07-05 07:07

11 楼

thanks for the suggestion. Not a fan of cursor myself either. I will see
what I can do to improve the sp.
the question I have is that, what could cause the report not returning all
the data even though the sp itself returned the data as expected? I thought
SSRS just treated all returned dataset as strings.

g*l2011-07-05 07:07

12 楼

你可以让DBA给你弄个固定的TABLE，你每次TRUNCATE，填充一下，你就什么都不用
RETURN了，我觉得你的STRING COMBINATION可能有问题

你把这个TABLE VARIABLE换成TEMP TABLE就可以了。date都用DATETIME，没事不要弄变
量，CURSOR全去掉。不要用SELECT *,有什么COLUMN就写什么COLUMN
declare @Results table (Group_Code nvarchar(10) not null,
Group_Member_Code nvarchar(10) not null,
Stmt_Date_Created nvarchar(10) null,
Stmt_Date_Updated nvarchar(10) null,
Stmt_Date_Approved nvarchar(10) null,
Supp_Date_Entered nvarchar(200) null,
Composite_Date_Pushed nvarchar(200) null,
Group_Composite_Date_Approved nvarchar(200) null)

gejkl,
Thank you very much for helping me answering my question. I was doing
research myself and figuring out the issue. You are right. I rewrite the
query to get rid of cursor and use PATH XML instead.
One interesting thing I observed is that after I updated my sp and run the
report, it gave out an error msg:
"An error occurred during local report processing.Exception has been thrown
by the target of an invocation. String was not recognized as a valid
DateTime.Couldn't store <> in Stmt_Date_Created Column. Expected type is
DateTime."
Which is much better than before when the report ran but returned no data
for this field. So I checked out the dataset and found out the data type for
Stmt_Date_Created was set as DateTime instead of String. This is quite
interesting because in the sp I declared the column as string and all the
rest Date columns were set as String as well and returned without issue.
So I went to the table adapter and manually set the datatype of Stmt_Date_
Created as String and vola, the reports display all data as I want.
Thanks again for your help.
Below is my updated sp. Hope it can help others. I was referering to this
wonderful article by Anith Sen. http://www.simple-talk.com/sql/t-sql-programming/concatenating-row-values-in-transact-sql/

TABLE设计的，创建TABLE的时候要先把类型定义好，别用ISNULL +STRING这种，给个
VARCHAR 255不就可以了么，你的TABLE VARIABLE也不好，搞个实在的TEMP TABLE吧，
TABLE VARIABLE放在内存里，快，但是你的TABLE定义的很乱，造成SSRS TYPE

繁琐。你不是就是要个确定的DATE么
CONVERT (DATETIME, @STARdATE,101)就可以了。我要找12/1/2010到1/3/2011，你这个
会不会出错呢。SUNQUERY可以用CTE替代，不会的可以用TEMP TABLE

The user does not want the full date time. What we want is a string of date
time with month and day
only .
The select input for temp table is
GroupCode, Date
AA 5/7
AA 6/8
The output is "AA 5/7,6/8,9/12..."
