Working With Multiple Datasets And Connection Strings
May 8, 2008
Hey guys,
I am pretty new to reporting software and I was just wondering in reporting services 2005 when working with multiple datasets and data connection string in order to populate text boxes if the data is a number it is prefixed with SUM at the start of the expression and if it is text it is prefixed with FIRST even though it is just for one value.
I was wondering if this is normal or have I messed up somewhere?
Many thanks.

Hello,
I am wondering how it is going to work using SQL Server configuration type to store connection string in the SQL Server table. How does SSIS know what database to connect to if its connection string is store in the database? Thanks

Hi everyone - I'm getting myself into a right muddle and am looking for advice.
How do people deal with connection string matters when taking a dataset defined in one assembly (and by default using the connection strings defined within that assembly in the settings files) and then using that assembly in an app (which also has a requirement to see the same physical database).
I'm not sure I've explained that terribly well but what I'm trying to avoid is duplicate copies of my database which so far seems to be the only way that I've managed to make stuff work. I'm not very experienced with SSCE data access (I'm a serices/sockets/ip person) and this may just be ignorance. Most of the examples seem to assume that the data is in the same place as the app whereas I'm trying to collate a whole series of functions into a helper assembly that I'd like to re-use for other things.
Ideally the dataset designer would provide an easy way of choosing from centralised connection strings - perhaps this is what the Dataset Project implies - but again the docs are mostly focused on SQL Server? Otherwise the best I've been able to do is make the connection properties public and try to update them that way or use a post-build action to copy the database from my datalayer project directory to that of my application |DataDirectory|
I suppose the question might be if you have a dataset containing multiple tableadapters that assumes one connection string, is there any easy way to keep such strings co-ordinated between projects without hardcoding them? With a server resource, the same non-specific connection string resolves to the same server (if that make sense) and this seems to be were I can't make the logical shift.
Does anyone have any thoughts and can they please point this SSCE noob in the right direction?
Cheers

I have a Save method in my class file that connects to my sql db to 4 datasets, which I then wrap together. I am currently instantiating 4 different Sql Client connections to do this.
Would it be more efficient to use just one?

Hi,
Is there any possibility of combining data from two datasets to a single report item. If there is any thing that we can do, can any one please tell me what to do, so that my problem will be solved.
Thanks

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

I have a report that I have created with multiple subreports and datasets. There should be a better solution so I am asking the question here.
The report should display like this:
Object
Object Title
Budget
Curr-Spent
Ytd-Spent
Ytd-Encum
Post-Ytd
Balance
% Remaining
4100
EMPLOYEES
$380.00
$250.93
$343.67
$0.00
$0.00
$61.33
15.94%
4102
EMPLOYEES - TEMPORARY
$149.00
$110.75
$139.70
$0.00
$0.00
$47.30
30.16%
4201
EMPLOYEE BENEFITS
$138.00
$73.16
$12.60
$0.00
$0.00
$32.40
25.28%
Each column represents another dataset.
Each column right now is a subreport so I can use the object as a parameter to the subreports dataset. Each column needs to have the object as a parameter.
Is there a way I can pass a field from the first dataset as a parameter for the next dataset without using subreports?

I have multiple different data regions on one report body. I need to be able to arrange the a few of the data regions so that they are grouped together and print together on same page. I've tried using a list around the data regions that I want to group together, but the list data region needs to have a data set specified and it only allows one to be specified.
Has anyone tackled this before?

I am needing to take data from one data set that consists of a list of parts and their stock information. Then I am needing to show any transactions that the individual parts may have had during the time that user defined through the filters.
This requires me to have two data sets since I can't do a join between the stocking information and the transactions due to the fact that it is very possible that every part won't have a transaction for each month of each year. Doing a left join still filters down the data too much so thus the need for two data sets.
I have these parameters:
Vendor, Year, Month, Type of request
Vendor and Type of Request is handled through StockInfoDataset. I then need to update the table showing 0 or transaction amount from TransactionDataset filtered by the ItemNumber and WarehouseCode that is in StockInfoDataset. Since it seems List and Table only allow one dataset in them, I am at a loss as to how I would go about doing this.
Explaining this is quite difficult in a forum post, but hopefully someone would be able to shine some light on possibly avenues to follow here....thank you in advance.

I have three datasets that are currently displaying data in three side-by-side-by-side tables. This gives the appearance of one large table were all rows match up nicely. Now, I need to somehow calculate the sum of those rows values across and display that value as a calculated sum at the end of each row. How can I access the values of each column from those three different tables in order to be able to add them together for each detail row. Or is this just a dream? Thanks in advance....Using SQL Server 2005. The backend queries that create those datasets are MDX and trying to manipulate those to get one dataset back will be a pain. That's why, I am hoping that there is a front end solution to this.

My company is implementing a multilingual solution for our application, so naturally the reports must follow. Every report I create has 2 datasets. It seems to me that the first dataset translates appropriately based on the browser's language setting, but the second dataset disregards the locale and just displays things in en-US. I've even created a sample report that accesses the exact same columns from the exact same view and dataset1 returns the correct language, but dataset2 returns en-US.
The report's language is set to =iif( User!Language = "fr-CA", "fr-CA", "en-US"), but I've also tried just setting it to = User!Language or leaving it at Default just to see if that would work.
Has anyone come across this before and been able to find a work-around?
Thanks!

Hello, I'm at a loss with this problem....
I have written many reports with multiple datasets but today I have something bizarre happening. I have three stored procedures (datasets) in this report. This is a rolling twelve month report that looks at three numbers (restraints, census, and percent of census) by month and year...pretty simple. The first data set is for the graph for all twelve months. The second and third data sets are broken out by MonthNum in matrix tables to show the first and then second six months in separate tables for displaying purposes...so that that they don't have to scroll far over to the right since I'm printing all the three values per month.
This should be no problem. What's happening is that when I refresh the report not all three datasets are displaying properly. Some times the data in the graph shows and some times it doesn't. Another odd thing is that in my matrix tables the restraint number and then percent values sometimes double or sometimes they are 0. What makes it even more strange is the census number is always there and is always accurate.
All the aggregates are calculated in the T-SQL stored procedure. So, all I'm doing in RS is displaying the values. It almost appears to be cycling through the datasets when I refresh the report. Other than the fact that the census value is always there.
I rebuilt the report with only the graph...no problem. Once I add another data set, every other time I refresh the report the graph has no data. I can't imagine what I'm missing as I've done this numerous times.
Has anyone come across anything like this?
Thanks!! Jamie

Is it possible to incorporate data from 2 datasets into a single chart? For example I have 1 set of data from 1 db which allows me to display datapoint "A" by week. I have a second dataset from another db which allows me to display datapoint "B" by week. I'd like to plot each of these separate datapoints on a single chart with the x axis being week and the y axis being a stacked bar chart incorporating both A and B values as individual data series. Further, assuming this is possible, is it then possible to have 1 series displayed as an area while the 2nd series is a column or line?

I have a report with two datasets, DS1 and DS2, which contain the same data fields, but with different values. Like so:
DS1 = sales
salesperson sale_number amount
John Smith 1 $100
John Smith 2 $105
Mary Jane 3 $98
John Smith 4 $275
Mary Jane 5 $92
DS2 = sales with price overrides
salesperson sale_number amount
John Smith 1 $100
Mary Jane 3 $98
Mary Jane 5 $92
Now what I want to do is see how the salespeople are doing. I can use either dataset and get great results independently:
Sales Results:
Salesperson Number of Sales Total Amount
John Smith 3 $480
Mary Jane 2 $190
or
Sales results with price overrides:
Salesperson NumSales with Over Total Amount
John Smith 1 $480
Mary Jane 2 $190
Now what I really want to do is a combo table like so:
Salesperson NumSales with Over Number of Sales %Overrides
John Smith 1 3 33.3%
Mary Jane 2 2 100%
I can not figure out how to do this. If I create a table that has DS1 as its datasource, I need to access DS2 for a count. So I try this for the NumSales with Over:
= count((Fields!sale_number.Value,"DS2"))
This just repeates the total number of sales in DS2, which is 3, for each line; not separating them out by salesperson.
If I try something fancier such as:
=count((Fields!sale_number.Value,"DS2", (Fields!Salesperson.Value,"DS2") like =(Fields!Salesperson.Value))
The report won't even run.
I want to do something along those lines. Does anyone have any ideas how to do this? I've considered subqueries to use salesperson as a filter, but the datasets are so large that the reports end up taking forever to run. I've tried using iif, but it doesn't seem to like using a field from a second dataset. I even tried to use the embedded VB code box to write a function, but then I couldn't pass the full array from the secondary dataset to the function (I could pass it from DS1, but not DS2).
I know this is incredibly simple, but this noob can't figure it out. If anyone has any suggestions I would deeply appreciate it.
Thank you,

Hello and thank you for the help in advance.
I know this has to be possible maybe I am just missing somthing.
I am creating a matrix report which will compare year by year quotes to orders The issue is quotes and orders each have their own dataset. I will be pivoting on JobType which is in both datasets and spelled the same. Is there a way to do this or will I have to figure out how to union the tables? If not possible why does it allow you to name the dataset in the expression?
Thanks, Leo

A report I am currently working on is a payslip report.
This report has multiple tables on the page, each linked to their own specific dataset.
Eg I have Taxable Allowances table linked to a dataset that returns information relating to any taxable allowances for an employee, then Non-Taxable allowances, Deductions and so on...
Taxable allowance dataset example
SELECT
TA.TaxableTrDesc,
TA.TaxableTrText,
TA.TaxableSubQty,
TA.TaxableTrRate,
TA.TaxableTrFact,
TA.TaxableSubTtl
FROM
Employee E
INNER JOIN TransCurrentMaster TCM ON E.EmployeeCode = TCM.EmployeeCode
CROSS APPLY udfReportTaxableAllowances(E.EmployeeCode, TCM.PaySequence, ) TA
WHERE
E.EmployeeCode IN (@EmployeeCodeParameter)
AND TCM.PaySequence IN (@PaySequenceParameter)
The report works fine when you select one employee.
Currently when you try to select more than one employee, all the employee results are displayed in the tables, for example, Taxable Allowance table contains all taxable allowances records for all employees on the one page...
I'm not sure how I can amend this report so that it is able to be run for multiple employee records...
Any ideas, thoughts, feedback would be much appreciated..
Cheers

I've got a GridView, a datasource, 2 textboxes and a button. If I choose to bind the GridView to the datasource the correct data is shown. But if I modify the datasource and chooses the TextBoxes as Parameter Controls it doesn't work out as I expected.
Can I please have a step-by-step response which will work? And expecially if one if the TextBoxes eguals nothing/null. Because this is very important, too, and that part doesn't work either.

I developed an application and deployed it onto a hosted provider. I use SQL 2005 Express for development SQL 2000 for production. Both systems work.
I backed up my production database and wish to use it for my development testing. I restored it as a SQL 2000 database on my development machine and changed my connection strings to point to it. I added it as a new Data Connection in Database Explorer and can see all of the data through it, but I see that all the tables now have the owner name in parenthesis as part of the table name.
My application now fails trying to find any of the tables. It works if I include the owner name as part of the SELECT statement. So much for data separation.
I don't know where to start. Is this an issue between SQL 2005 Express and SQL 2000, or is it an issue between SQL and ASP.NET, or is it a hosting provider issue, or what?????

Hey guys, don't know if this is in the right place but here goes.
I'd like some advice on optimizing the way I write my code. Here's the scenario. I have a select string for 3 different tables. One for the main gridview, and two others that are binded to dropdownlists.
So I created a Sqldatasource1,2,3 and had to create the connection strings for each one.
ex. SqlDataSource1.ConnectionString = "blah", SqlDataSource2.ConnectionString = "blah", SqlDataSource3.ConnectionString = "blah"the thing is, the connection string itself is the same. Is there a way to consolidate that? So that when I use a select/update/insert command for each sqldatasource i dont have to have another connection string? Also, having multiple connectionstrings, does that slow down the performance?

I have created a SSIS package, and got it to perform as I want.
I am having a problem though with connecting to my data source (OLE DB Source) using SQL Server Authentication.
If I use Integrated security, I have no problems. If I use SQL Server Authentication, I get errors.
Here is the connection string that works:
Provider=SQLNCLI.1;Data Source=.SqlExpress;Integrated Security=SSPI;Initial Catalog=MyDataBase
Here is the connection string that fails:
Provider=SQLNCLI.1;Data Source=.SqlExpress;Persist Security Info=True;Password=**********;User ID=myUserid;Initial Catalog=MyDataBase
The strange thing is that when I use the Connection Manager dialog screen and click on "Test Connection", I get the response that the connection succeeded. It is only when I try to run the task that I get an error.
Here is the error I am getting:
[OLE DB Source [1]] Error: The AcquireConnection method call to the connection manager "MyDataBase" failed with error code 0xC0202009.
[DTS.Pipeline] Error: component "MyDataBase" (1) failed validation and returned error code 0xC020801C.
I have eliminated the obvious errors (incorrect Userid or password). Also, I am unable to use Integrated Security as this package needs to be distributed to various systems that may or may not be on our company's primary domain.
It seems I am missing something really basic here, but am not seeing it.
Any thoughts?

My report has two data sets that hold inventory from two different departments.
ds_DeptA and ds_DeptB
I have a table, that pulls the DeptB status of DeptA record and displays it. This returns empty when the lookup fails to make a match, which is fine. Typically means DeptB does not have the record yet. I need to count these empty (null) feilds and populate it in a Text box outside of the table.
I just can't figure out the syntax with multiple datasets. I can't use the lookup expression as part of the count expression since the count expression is not contained in a table that has a dataset.
table: ds_DeptA
fields:
ID
Name
date_set_to_DeptB
<<Expr>> =Lookup(Fields!ID.Value,Fields!DeptA_ID.Value,Fields!DeptB_Status.Value, "ds_DeptB")

We have a report that was created in SSRS 2008 R2 that has 3 tables with different datasets that share a common ID that I want to use to group them.
If we run the report passing only a single value for the grouped parameter then the report works perfectly. What we need is for this report to allow multiple values to be selected for this parameter and for the report to run as if the user had selected each value one at a time and run the report with page breaks in between. Currently, when we pass multiple selected values for the grouping parameter the report displays all values for table 1, then all values for table 2, then all values for table three as below:
Table 1:
Detail rows for Group Param Value 1 ...
Detail rows for Group Param Value 2 ...
Detail rows for Group Param Value 3 ...
....
Table 3:
Detail rows for Group Param Value 1 ...
Detail rows for Group Param Value 2 ...
Detail rows for Group Param Value 3 ...
But we want it to render like this:
Table 1:
Detail rows for Group Param Value 1...
Table 2:
Detail rows for Group Param Value 1...
Table 3:
Detail rows for Group Param Value 1...
[code]....
The page breaks are needed so that when the report is exported to excel each individual report (by group param) will be on its own uniquely named tab.The report must export cleanly to excel and currently does for the single value passed.

Hi,
I am looking to allow a user to select which database they need to connect to, and then for them to be able to use that connection string until they choose a different database. I have a separate database specifically to hold the list of databases with the respective connection strings, and various forms that are currently looking at the web.config for the connection string. Unfortunately, I can't just put all the connection strings into the web.config as the number of databases available to the user will increase on a weekly basis which will be handled by a database administrator, so I want a user to select from a list of databases (for which they have permissions), and for that connection string to remain for that user. Potentially there will be 20 or more users each connected to a different database (all SQL Express).
If anyone can provide any help on this I will be truly thankful as I've hunted on the internet for hours and have been unable to find anything that has helped.
Thanks in advance.

Dynamic connection strings
I have found lots of people asking for something similar to this but cannot find any solutions - can you help?
I am developing an application (ASP.Net2) in which users are associated with 'Clients' and every Client has their own SQL Server database.
Users are authenticated using standard ASP.Net Authentication via a separate database (common for all users). This includes a table linking them to a Client and each Client record includes the connection string to their database. Currently a default connection string is held in the web.config file.
My problem is that I don't know how to dynamically change the connection string after a user has logged on. I have a large number of databound controls, many of which are declared and some are coded in the VB.Net code behind. I know I can use code behind to change the connection string for a SQLDatatSource:
I thought I had it cracked with the following:
Public objClientConnection As New ConnectionStringSettings
Public Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)If Session("ClientDBConnectionString") <> "" ThenobjClientConnection.ConnectionString = Session("ClientDBConnectionString")objClientConnection.Name = "ClientDBConnection"objClientConnection.ProviderName = "System.Data.SqlClient"ElseobjClientConnection = ConfigurationManager.ConnectionStrings("WebTool1ConnectionString")End IfEnd Sub
The session variable Session("ClientDBConnectionString") holds the client specific connection string and is populated when the user logs on. If this is not populated then the connection string defaults to one collected from web.config. This should ensure there is always a design time connection string available.
The trouble is, when I try and declare the SQL data souce like this:
<asp:SqlDataSource ID="dsTest" runat="server" ConnectionString="<%# objClientConnection.ConnectionString %>" SelectCommand="usp_SEL_DocumentTypes" SelectCommandType="StoredProcedure" ></asp:SqlDataSource>
I get an error: The ConnectionString property has not been initialized.
I have been going around in circles on this for days and would really appreciate some help. Am I on the right lines? What needs to change to make it work? Is there a better way?
Many thanks,
Cliff

Hello,
I'm trying to setup a typed dataset with a table adapter in .NET 2.0, and the problem I am having is that I cannot get the table adapter to use existing connection strings setup in the web.config file. How can I get it to do so? It doesn't see the connection strings, and so it wants me to create a new connection, which I don't want to do.
