I have to work in two parallel environments, developement and production, I want to use the same TableAdapter to connect to different databases (two Oracle databases running on different servers) with the very same structure. How is this possible?

Actually the above entry is added to DA..but how do i update it to the actual DateBase, DB1?
I've been struggling the entire day trying to figure this out. Basically the data in my form won't save to the tableAdapter. To update the database I use:
Me.dataSetName.TableName.Rows.Add (DataRowName)
Me.tableAdapterName.Update(Me.dataSetName.TableName)
The database was created using SSMS 2008 R2 and I'm using VS 2010.
I have confirmed that the data is being stored in the data row (because when I removed data from the data row it wouldn't accept because there are NOT NULL columns) and I have followed the instructions of this form as well:[URl]..
Created dataset with tableadapter.Dragged dataset and tableadapter to the form so I can reference it in code.New records successfully add to the dataset but will not commit back to the database.Gives no error or clue why it won't work.TableAdapter insert statement was created automatically and is parameterized (@p1, @p2, etc.), but I am trying to avoid those parameter.add statements as I want to be able to use a field-by-field format without having to essentially repeat the schema of my database in code with parameter.add statements.Command object and INSERT statements work fine, but then you always have to construct an INSERT statement -- a pain if they're complicated.I want something as simple as working with a ADO recordset,but in .NET.What can I do to accomplish the following without parameter.add statements?

I have a table adapter for a fairly sizable piece of data. Now with this data I would like to give the user the ability to change the company name and have this reflected in the form on the drop down list of all of the companies once they have clicked submit. However, in order to do so I currently "Fill" the entire table adapter again to achieve this.Is there any way which I could just re-fill the company column from the database in the same tablea dapter.Here is my code for the sub:
Dim NewName As String = txtNewName.Text
Dim OldName As String = txtOldName.Text
Dim FieldName As String = Me.Text[code]...
I use this save code which is generated when I drog and drop table from data source to form[code]...
View 1 RepliesI was working through Beth Massi's article, "Using TableAdapters to Insert Related Data into an MS Access Database" here: http:blogs.msdn.co...s-database.aspx
And I configured the TableAdapter exactly as shown by Beth, yet I am getting an error here:
Me.OrderDetailsTableAdapter.Update(newOrderDetailsRow) The Error says: "You must enter a value in the 'OrderDetails.CustomerID' field."
I am using this code for inserting a related record:
Namespace MyDataSetTableAdapters
Public Class AccessIDHelper
'<summary>
[Code].....
I am not able to insert and move on as I am getting the error marked above.
What could be possibly wrong with the above code and why is this giving an error ?
I'm using Visual Studio 2010 Express running on Windows 7 64-bit. I get the same error as detailled in this link [URL] .I need to work with some data to develop the system. I think I can only do this by changing the Copy to Output Directory file property to "Copy if newer" to prevent the debugger from losing it.However this causes TableAdapter.Fill to exit from the sub immediately after executing leaving behind the other code in the form "Add_Load" routine.

I'm using TableAdapters in VB.NET (VS2008) to an SQLCE DB. These are associated with a range of DataTables in my DataSet.
I'm trying to simplify my app and I'm wondering : If I call the Update method of a table adapter and there have been no changes, then will the TableAdapter still open the underlying database, or is it smart enough not to bother?
At present I'm using simple boolean flags to keep track of which DataTables have modified data - and it works fine - but I'm just thinking I might be able to simplify my code just by always letting it call the updates. But I only want to do if it won't add an overhead.
I have a form that has a datagrid thats being filled by data from a temporary database (called Scratchpad3) and what I'm needing to do is to update another table that's not part being called with my table adapter. My table adapter looks as follows:
Me.Scratchpad3TableAdapter.Fill(Me.MDRDataSet.scratchpad3)
and the table that I need to update is called ExceptionsEdit.
I have a VB windows Form project that connects to several DataTables in an Access DB. On my form I have several textboxes, comboboxes and datetimepickers that are bound to those sources. With one table in particular when I try to update the tableadapter after editing one of the textboxes the update method fails. No exceptions are thrown, but the update method returns a zero value and the data is not updated. The update will work when just the comboboxes or datetimepickers are edited, but as soon as a textbox is edited also, update will not work.
Other DataTables within the project are set up in the same manner but are not having update issues. I can't figure out what about this one particular table is causing an issue. Can anyone give me any thoughts on where or what to troubleshoot?
I have a DataGridView on my form and I'm wanting to override the 'Add New Record' button on the DataGridView controls, and display my own 'Add record' form. The problem is, when I do so, I no longer get the Auto-increment functionality of my primary key field (as i would If i used the default functionality of that particular button).

Would I be right in saying that when using tableadapters that you can't get the identity value back from the tableadapter when you insert a row intot a datatable then save the table back to database using tableadapter.update(datatable).It will only return the value of 1?
I would like to return the identity from the table but didn't want to have to assign all the parameters manually in code cause theres about 30
I would like to start a data base. Im using vb2005. I've started a new windows application. I have added a new data source to the project. Then I added a new TableAdapter in the dataSet.xsd part of the project. When I'm completeting the wizard, when I click on the QueryBuilder, when the add table window opens, the table already in the program ( that comes along with the TableAdapter ) isn't recognized. I've clicked on the refresh button but it still isn't recognized. (example: DataTable1 isn't recognized in the add table form in the query biulder of DataTable1TableAdapter)

View 6 RepliesI have code that saves changes to data on a form and it works fine. I then used the same code on a different form (only changing the name of the bindingsource and tableadapter), but changes I make to the data don't save. Why will it work on one form, yet not on another? Here is the code I am using to save the data on the form that works:
Dim deletedRecords As DataDataSet.CatalogDataTable = CType(DataDataSet.Catalog.GetChanges(Data.DataRowState.Deleted), DataDataSet.CatalogDataTable)
Dim newRecords As DataDataSet.CatalogDataTable = CType(DataDataSet.Catalog.GetChanges(Data.DataRowState.Added),
[code]....
The only difference I see is that on the second form (the one that won't save) I have other tableadapters loaded. But they are just used to load data into different comboboxes. What could be causing the second form not to update the tableadapter? I'm not talking about running the application, making a change, then closing the application and it not saving. I realize that a second database is created because I've set the Copy to Output Directory property to Copy if Newer. I can tell it doesn't save because I run the application, open the form, make a change, close the form, then open the form again. The change I just made is gone.
I have a program that is using a dataset class, table adapter, binding source and binding navigator. The program can read, update, and delete rows from the table. However, it doesn't recognize new records and save them to the database when the table adapter's update method is called. (table was pre-populated by another process) The database table is using an identity column for the primary key. On a whim I added code to force an insert of data using the table adapter's Insert method with some hard coded values and this worked.This code was invoked after hitting new record on the binding navigator bar. Looking at the database, I notice the record I forced in skipped an identity value, which indicates to me hitting new record took the previous number. So the question I have is what would keep the tableadapter from inserting the new record when its update method is called?

Here, Name is a string and the other are integers. The generated signature however looks like this:
InsertQuery(int Color, string Param2, string Param3, string Param4)
Which does not match the query, either in name or order of parameter types.How can this happen? Any fixes? It also throws back errors at runtime for type mismatches, which don't occur when the parameters are in the 'correct order' in the query builder.

I need to get information from two tables onto my form. I'm using a DataGrid called SQLGrid which I'm populating in code with the information I need to get out of both tables.
Private connstr As String = "Data Source=MAUDOT3;" & _
"Initial Catalog=ExxColl;" & _
"Integrated Security=True;"
[code].....
I need my application to be able to update the DataGrid, and commit those updates to the database. My problem is that all the research I've done so far has led me to believe that there's no way I can do this because the SqlDataAdapter.Update() method only updates 1 single table.I just had an idea to make my event handler execute a stored procedure that creates a view on the database, populates it with data from my dataset, and then distributes the information between the two tables where needed.I guess another solution would be to use 2 DataGrids and then tie each of them into a seperate DataAdapter/DataSet, and then update each when the Event is called. The problem here would be that it's more work for the end user to make changes, so I'd really prefer to do it another way.
I have a query in a myTableAdapter that ends with WHERE column IN (@S). This works fine when I use myTableAdapter.Fill(dataset.table, "text") but I can't find any way that works to provide multiple text strings such as "text1, text2" for the IN parameter.

someone pls help me with this.
I am writing some data to my Database using TableAdpater.Update and the operation can take up to one minute to complete.
Is there some way to report the progress of this to the user because they think it has stopped responding.
Instead of using the binding navigator, I would simply like to use buttons. I'm familiar with the .Fill/.update etc. But what would create a new record?
Using:
