In a nut shell what I am trying to do is, pull one or more tables into a datagrid view. I am having one heck of a time returning multiple datasets. I can eleect all indavidually, but when I try to select more than one, I only get the last "table" in the list. If I could establish a ODBC connection that would be better, but this will have to work for now with some canned queries I have.

I have two databases. One is an SQL database and the other is an Access database.
In the Access database, I have a table with three columns EMPID, FIRSTNAME and LASTNAME.
I load this in my VB program to a table called "EMPID_Table"
In the SQL database, there is a table that has a lot of data that I need to retrieve based on the Employee#, which is the same as the EMPID from the Access database. In my VB program this is loaded into a table called "WagesTable"
How can I merge these tables, or add the columns FIRSTNAME and LASTNAME to the WagesTable
to the correct Employee# in my VB program? I cannot change the SQL database at all, I can only read from it.
Access Query:
Dim EMPID_Query As String = _
"SELECT *" & "FROM [EMPID_Table]"
'This returns EMPID, FIRSTNAME and LASTNAME
'I fill this to a table called "EMPID_Table"
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 have got a database with a bunch of tables in it. So far, i can query that database and get the names of all the tables into a listbox. this is sweet.
What i need to do now is to enable the user to click on a table name thats listed in the listbox (which were put there using the
GetOleDbSchemaTable method)
and when they do, i need to populate the Datagridview with the relevant data thats sitting in the table that is listed in the listbox.
I've tried a couple things to get the tables themselves to populate the DGV(which kind of works now), but not the Data thats sitting in the individual table.
I am trying to merge 2 datasets from 2 different servers, SQl 2005. I need to take 2 fields from one table and five from another to create one merged dataset and bind it to a datagrid, in an 2008 ASP.net application. The first table I will be saving to is empty just the table schema is there, The second table that the datagrid is populated by, has two columns containing dropdown box and a text field for user to edit these fields, these will be saved into the first table along with the user information, and a time stamp, but when a user pulls this information again the changes in the datagrid will reflect these changes.

I have 2 DataTables in vb.net. Each is populated from it's own stored procedure. Table A contains a project number in the first column. Table B also contains the project number in the first column. Table A could have many records that have the same project number, but Table B will always have just one record in it per project number. I would like to append the data from Table B to every matching record in Table A. How would I do this?

I'm looking for a way to combine a field from multiple tables into a single field in a new table. Because the data populating the tables is coming from an outside source, I would prefer not to change the data in the original files. I have a separate table for each year because this is the way the data is provided. The field layout is not consistent from year to year, but each year there is a field that we'll call "score." I'd like to pull the field "score" from each year's table and have it populate a "score" column in a new table along with the year of the data so that all the years' scores are in the same place. Is there a way to do this using Visual Basic + Access?
View 3 RepliesUsing Visual Basic 2005 So this is the problem I have run into. I need to populate a Datagrid with Data from 4 different tables of which I have gotten down to 3 DataTables in one DataSet.
The first one is called Letters and includes: LastPrintedOn & requiredpaper The second is called ImportParams and includes: ImportParamsID, BlockLetterGroup1, BlockLetterGroup2 and BlockLetterGroup3
The Last is called ClientInfo and includes: ClientGroupID, CapturedOn, ProcesingCommittedOn, ProcessingStartedOn, ProcessingCompletedOn, ImportParamsID
Now I can attack this from one of two ways (at least that is how I see it)
Select the ClientGroupID's I need (1,2,3,6) from that I will have the ImportParamsID which will then get me to the second table which has the blocked letters 1, 2 or 3 of them of which I can then check against the last table to get the date. There is one clients as of now that will end up with 3 thus being 3 seperate lines on the DGV or Table to show the different letter types.
Method 2:Bascially the reverse, look at the letter types and work backwards though I think the first method is easier. Where should I start? I'm not looking for code but the path I need to be on to get to the end.
I have 2 tables : product (as parent) and sales (as a child).
[Code]...
product_id at the product table is pK for product table. transaction_id at the sales table is pK for sales table . product_id at the sales table as fK, which a reference to the product_id of product table All my tables are stored in the dataset. How do I get the data from these datasets can I view on the DataGridView with a different layout formats, as follows.

View 1 RepliesWhat I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I have an ODBC connection to a database, I have 2 tables items, prices. both tables are related via a sequence field. I need a way to load the 2 tables into a datagrid, update fields and then save the changes.items-- itm_seq-- nameprices-- price_seq-- itm_seq-- price_1-- price_2Datagrid needs to show the data as suchname / price_1 / price_2Site updates some cells of the data, hits update.
The records are then written back to the 2 tables accordingly based on the sequence number.. I tried a view that extracts the data and then allows updating, but the datatableadapter will not allow an update statement to be processed against a view.
I would like to have a datagridview sourced from multiple db tables.I understand that the datagridview relies on the creation of a datatable and its relations to the separate db tables I want to view.
I have been mucking about with the Designer but dont seem to be getting anywhere, ie. no results from the relations i've built seem to populate the datatable.
I used INNER JOIN to bind the two tables and my problem is how to populate/show on the datagrid.[code]....

View 1 RepliesWhen 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?

There is a "how do I video" on how to properly control updates, inserts and deletes in multi-user applications on forms that edit master-detail related data. [URL] Massi worked through the process using Order (OrderID is PK) as the master table and Order Detail (OrderDetaiID is PK) as a related table in dataGridView. The dataGridView automatically generate orderDetailID whenever the mouse enters in a new row. I am doing a similar form, but placing order form and orderDetail form in two separate tabs in a tabcontrol, and also using Details view for both tables. When I click "new" button in BindingNavigator, the orderID is automatically generated. If I use dataGridView for my orderDetail tab, then the orderDetailID is automatically generated when the mouse enters. This allow me to insert/update tables correctly. However I need the Details View for my orderDetail form too. How do I get a orderDetailID automatically generated when user insert a new order and have the mouse click on OrderDtail tab?
View 1 RepliesI do no know how to go about doing this. I have a view in the db. I have gatheredall the data in that view. Now when clicks a button, i want to transfer half column data in the view to header_table and the other half into the lines_table. Also once it is transgered, I want to display it in a grid view. This time all the fields from header_table and all from lines_lines. Can someone guide me how will I do that by an example of code that is not very complecated and does what I want to do?
