SQL Reporting :: Link Multiple DataSets Then Put Data Fields From Multiple DataSets Into One Data Region?
Sep 23, 2010
How to link multiple DataSets (why SSRS call it a DataSet even there is only one bunch of data fields in it) using keys, then put data fields from multiple DataSets into one Data Region? The reason I have to do this is: There will be 6 major DataSets to be used together few times in same report, it is not make sense to build a huge Matrix for all of them together. (in some data region I use data from dataset A and B, some times I use data from dataset A and C, D ...)

I need to display a header and details. What's the recommended way to do this? 2 separate datasets/tables, or 1 dataset with 2 datatables in it? I can't get the second set of data to display.

I have two datasets called ds and ds1 that I want to merge into a grid. I get data from the first dataset to display in the grid but the second dataset where I want to display a count I don't get any data from it. I am trying a ds.Merge(ds1). here is the code i have for the sub. What am I doing incorrectly?

I'm extracting data from a webserivce.
This is my select statement to retrieve the data:
string cmdstr = "select title, titlefr, racpnr, racpmodeltype from onl_wgn where show = 1 order by onl_kl, racpnr";
I got 4 groups of onl_kl. Now I want to show each group in a tab of the jquery tabcontainer.
I can pass the data in a dataset from my webservice to my webapplication and databind it to a listview, but I don't know how to seperate the data into the 4 tabs? Is this possible in a way with a listview or using other datacomponents?
If not, should I make 4 select statements in my webservice and send 4 datasets to my webapplication and bind it to 4 listviews each in 1 tab? If so how I can pass a list of datasets from a webservice to a webapplication?

What is your opinion of DataSets vs. just stubbing out custom classes and working with those? What are other alternatives?

I have a good bit of data that is generally static. I want to load it into my application so I can access the items from picklists without having to make redundant calls to the database. I have found a few articles discussing how I can approach this, but, I am specifically looking for a way to create a collection of DataSets with constraints at Application_Start. Also, when you do this kind of thing, do you normally create one dataset or a separate dataset per table? I know there are ways to add multiple tables to a single dataset, but, I don't know how to do this from the DataSet Designer.

I want to serialize an object to json, so I'm using [Code]....
[Code]....
This is fine, but I want to return different json datasets depending on the circumstances. Lets say I have this object (a simplified example):
[DataContract]
class foo
{
[DataMember] int productId
[DataMember] string productName
double price; //not used in json.. yet
}
Which will serialize to a json object containing the product name & Id, but what if I also need to be able to return a different json object (say, productId and price but not name)? Can this be done somehow in the same object using WCF/DataContracts and DataMembers? This will be sent in an ajax query containing a collection of objects and needs to fast, so just including every member in every type of json request whether it's needed or not isn't a good solution.

I was just thinking if there was a way to programmatically open and close connections to the database via the dataset classes we've added into the project.
I am trying to avoid one specific problem. Assume there is an EmployeeTableAdapter. It has two methods IsValid(string EmployeeID) and HasDepartmentAccess(string EmployeeID, string DeptID). Afaik each of these methods, open a connection, does data retrieval, and then closes it.
The opening and closing of the connection is done internally. I kind of want to override this, and close the connection upon a page unload event which (I'd manually register it with the datadapter class somehow).

I have a dataset dsvalue that has columns Id and views. An other dataset has quite a number of columns including Id. So for each id in dataset ds, i should add a new column "Views" and merge it with views from dsvalue.

I have a website and it was running great but wanted to move my business logic/datasets over to its own project.
That seems to be working well, I can access my functions etc from my bl dll. But I cant access my tableadapters like i used to be able to directly.
Do I have to make classes that access all those tableadapters or am I missing some reference I need to add?
I seem to be able to get the dataset for example mydataset But the intellisense doesnt pull up mydatasettableadapter

How do you control database server access when you use datasources in VB 2010?How do you access multiple tables from a store procedure using datasources?
Explanation:My experience is with VB.NET for the most part. I've written a lot of apps drawing data through dataadapters into datasets and processing them to provide reports in aspx.
I'm starting to work in VB 2010 and those elements are no longer available. What appears to be the weapon of choice is the datasource.What I'm not seeing: 2 important things that I can't work without:
1. Control over when the database server is hit with a connection request; daMyQuery.Fill (MyDataSet) was an explicit command that I could use to collect my data on demand. From that point on, I could use the dataset as I wished to populate whatever controls or structures I wished - the database server was no longer needed and wasn't hit by my apps until another pageload.
2. Multiple Tables in a query result; This must be there, I just can't find the method by which to reference different tables in my SQL output. Previous, I would have a dataadapter which would use a stored procedure to deliver a dataset of multiple - sometimes many - tables for use in the application. I can't find the equivalent on a datasource.
So my two big-ticket needs - requests for assistance, really - are listed above: How do you get at multiple tables returned from a stored procedure;and;How do you keep datasources for hitting the dbserver whenever you use it if there is no equivalent to a 'fill' method?
I guess another - how would you walk through the rows of a dataset?

I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects.

I have been thinking about the optimal way to create an XML file using data from a Dataset AND according to the rules of an XML schema. I've been searching around for a bit, and I failed to find a way in which I only take the data from the Dataset and put it inside a XML tags, with the tags being defined by an already-existing schema. So it might go like this:
1- Create Dataset and fill its rows with data.
2- Create an XML according to an XML schema rules.
3- Fill said XML file with data from Dataset such that data is taken from the Dataset while structure of the XML file is taken from the XML schema.

i am using datasets as part of my web application architecture.
i have one dataset which has two tables which are populated from database . everything works fine but when i have change in stored procedure. i change structure of datatable in dataset file after that compilation errors start to throw up. when i check cs file of dataset it shows multiple classes with different names.
cant get into it. since im using datasets for first time. its getting frustating.
