I have multiple tables that I need to pull and display data from. I have created a new query in the TableAdapter of one table to pull data from related tables based on a parameter. In the Query Designer I can run my query and see all of the columns requested in my SELECT statement, however when I bind this table to a DataGridView and call the new query, it only returns the original columns from Table1.How do I see all of the columns I selected in my query?

When I update a record at table [Product] with the integer that stands for [Supplier Name] from joined table [Suppliers], this does not appear in my datagridview. Instead, I have to reload the table to dataset to make it visible. What about datarelation? Is it better that loading a joined table over the dataset? Note that I have never dealed with datarelations before.. How can I make a datagrid column to show "Supplier Name" instead of recordID that represents this supplier?

On a VB.NET 2008 form I have a DataGridView, BindingSource and TableAdapter.The BindingSource DataSource is a dataset.In the dataset I have a Fill command that joins three tables and this is displayed without a problem in the DataGridView.However, I am unable to Update the dataGridView because it has multiple tables from a single TableAdapter? Does anyone know a simple way I can update. The tables has over 200 columns and I only want to update the columns that are changed. If I use a single table I can edit data in theDataGridView and the database is updated ok.

I'm having a hard time joining 2 datatables and have the joined datatable as result. First datatable (labels) holds data including a printerid. Second datatable (printers) holds printer references (id > unc). I would like to have as endresult (joined) a datatable with all data from the first datatable with the field (unc) of the second datatable. [Code]

I'm an experienced Office & VBA programmer, I am new to .NET programming. I'm in the process of migrating an Access 2007 database application from Access to Visual Studio Visual Basic project for further development. In particular, I am interested in using .NET controls to display data in a user-friendly hierarchical grid control.The data for each hierarchical display is stored in two separate tables (I call them tblData and tblExtraInfo), and then I use a query to join the data and prepare for display (I call the query qryBOM).

I've been working with a remote mysql database. The design of the database pretty much requires that I use SELECT commands that include multiple tables, and sometimes joins. Updating a single table query is SO EASY, yet dealing with multiple tables has me pulling my hair out.
[Code]...
What's killing me is that if I make a change to a field in the products table in the datagridview and press button1, the changes are saved. If I make a change to a field in the specials table in the datagridview and press button2, the changes are saved. If I combine the two updates together in a single routine, only the first one is saved. I presume this is because after the first update executes, the dataadapter no longer reports that there are any changes to save, since the update already happened.
I've tried breaking this up into separate dataadapters for each table, but then even using dataset relations, I can't get the data together in a single datagridview. On top of that, the grid itself is only intended to be used for searching and querying data. It still needs to be bound along with a set of textboxes that accept the input.
Lastly, this database is part of an ever-evolving website database with dozens of tables that need interfacing. I just can't see manually maintaining hand written sql statements for every table. That's why I've been working so hard to get the commandbuilder to handle it.

I am a new user. Apologies if I am posting this in wrong place and also if it is repeated one. I have few queries:
1.Is it possible to store multiple tables in a single DataSet?
2.If yes then it is a good practice? or should i prefer having separate connection object, separate DataAdapter and separate DataSet for each of the table to be accessed? I am new to VB.NET and using VB.NET 2008 Express and MS-Access 2007 as backend for my project.

After making the changes or adding a record I use invoke childmethod from my toolbar to call these subs. The first table updates and adds, but the second does not. I have set all of my textboxes databindings and double checked them. I get no error, but it does not update the second table. What am I doing wrong?

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand

We are presently developing an application, let's call it APP1, which uses a SQL Database which have about 800 stored procedures, 600 tables, etc. APP1 was originally created in order to replace another application, APP0, from which we do not have source code but only SQL tables, Stored Procedures, views, etc. Previous programers of APP1 used some DB objects from this same database and added some other objects specific to APP1 because it becomes bigger than APP0. And we do not need APP0 anymore as APP1 does all what we want, and more.
So, now, we are thinking about a way to find out which objects are used by APP1 in order to remove objects which are ONLY used by APP0.What is the best approach to discover all objects used by APP1 without having to open every single class and form?
Once we will have a complete list of these objects, it will be easy to use a program we bought which detects all dependencies for all SQL Objects specified directly from SQL and remove objects which do not return from any dependencies. Any ideas of how I could get this list without having to go through all our program that have many, many, many classes and forms?
Note : I know, in a perfect world, all calls to PSs and tables should be in a DAL but in the case of the application we're presently working on ... this is not our case! Yippy! (sarcastic yippy) ;)
Note 2 : This application is not using any ORM. So all queries are directly using SqlCommand. So any call to any DB objects are in string format.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

I COMPLETELY understand how redundant this is but I NEED it.Upon users creating a User account which only contains the ID, Username, Password and CustomerID I must also have a record in Customers create itself but null everything and the User.User_Customer_ID must update to the newly created Customer.Customer_ID
I have everything working but this pesky update query. The ONLY thing it needs to do is change User.User_Customer_ID to Customer.Customer_ID I managed to story the User.User_ID in an integer called UserID and Customer.Customer_ID in an integer called CustomerID I have tried a million different ways with no success

I have an application which upon a save button needs to save data to 8 different tables. 7 of those tables will have multiple new records added to them, while 1 will have just one new record. I want to encapsulate this giant Insert operation in a Transaction so that it will not complete unless I can save successfully to all tables.I have considered using Insert commands to a command statement, but adding what amounts to like 50 parameters, and the fact that using a parameterized query means it becomes very difficult to troubleshoot problems such as invalid values in the SQL statement (since I cannot figure out what the statement looks like with values in it
