Cannot Update TableAdapter Data From Multiple Access Tables
Mar 24, 2009
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 have two tables that i got from northwind Database and made one out of it from order_details and products and the new table is DataTable1 it has data from both previous tables how do i update that new tableFPENA
i think you can already picture it out... so what i want is to display data from Transact table and also display the data from Student and AddBook table base on the value of the foreign keys in Transact table....
have a datagridview containing 2 tables left joined, so that:table1 LEFT JOIN table 2 ON table1.id=table2.idI get an error whenever I try to edit my datagridview."invalidOperationException was unhandled by the user codeDynamic SQL generation is not supported against multiple base tables."The error points to this line:
da.FillSchema(dt, SchemaType.Mapped) da.Update(dt) << This line 'da = dataadapter
I have a database with numerous tables all containing the same field. the field needs to have the same value in all of the tables, but currentlydoesn't.Is there a way to use Visual basic codehat goes to each table and updates the field in all of the tables without having to manually go to each table and update the field?
I am trying to fill a temporary table with one column( a code) with the unique results of three queries of their respective table adapters.I can't figure out how to do it from here.The database is Access 2007 and I have activated the appropriate dataset on the form from which this code executes. The table adapters are part of that dataset.I could try to use the recordset approach, but that means making another connection to the same database.Is that a preferable approach?My purpose in doing this is to build a VB process like the one that works in a VBA Module of this Accessdatabase, partly to help me learn VB2008 and partly to overcome the necessity to keep updating queries used by the module.Code below
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'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.

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 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 have two tables 1) tblRequests and 2.) tblMainTags. The Fields in tblRequests are Tag_Request_No, Employee_ID , Accepted, Accepted_Date, and Accepted_Time. The Fields in tblMaintags are Tag_Request_No, Tag_ID, Completed, ... The fields 'Accepted' and 'Completed' are set to YES/NO.
I have an office project which shoudl basically do the following:
1) take different TEXT files of fixed-length fields and put them in separate tables.
2) use the data from the different tables and compile them to a master table in a mdb.
3) display data in compiled mdb in datagrid 4) allow editing in datagrid 5) save the data in datagrid into the mdb 6) save the data in datagrid in a csv file i did some googling and came up with the following code:
so ai have created this new TableADAPTER in my dataset, and it pulls data from two different tables namely card and transaction. I have created a datagridview to see the result, however when I try to filter the result, nothing is returned to fatagridview.
i wanted to add data from a single form in vb to two tables in access but an error appears saying that the field customer_ID down to Contact_Number doesnt belong to the table record, though it really doesnt belong to that table.. but i already indicated the table for the customer_ID down to Contact_Number, which is Customer, in my sql statement...

if it affects the run time of a program if I were to have multiple data tables as opposed to one data table with all my data in it? I am trying to minimize datagrids and just use code to access table data, in hopes that it will speed up my program. But I am ignorant if multiple tables vs 1 main table will make a difference because there will still be the same amount of overall data present in my program one way or the other....?
This is a winform and I'm using mysql as a database, here is my code:I'm trying to add data into multiple tables.[code]Index and length must refer to a location within the string. Parameter name: length
I am used to creating a data set with data from one table, for instance:

Now I am needing to add a second table. For instance, my second table "EQUIPMENT" has a field called "DESCRIPTION" that I would like to add to my dataset. The "WORKORDER" table has a field called "EQNUM" which is what the "EQUIPMENT" table uses as the primary key. how to combine these into one dataset?
I have a VB.Net dataset that contains data from multiple tables. how to query data out of the dataset. I want to run SQL-like queries on a dataset to extract data that fits a certain "where" statement.
i've a form which displays data from multiple tables of the same employee(personal details, salary details, etc...) and have a common field 'Empnumber'I want to retrieve data from all of them to be displayed in the form. Am not getting the sql statement required for this. the code i use is, rs.Open("Select * From employeetable,payroll,misc where employeetable.EmpNumber='" & text1.Text & "'", CONN, 3, 3) where text1 has the empnumber for which details are required and empnumber is the common field in all the tables...
I fill DataSet from Access Database then create Datagridview to display data. My problem is how to Save Data back to a different table in Database then the one used to create the DataSet? I'm using Visual Studio 2008 and Visual Basic 2008.Original Table used to fill DataSet is called RecordList the new Table will be RecordListReport.
I am new to VB and I have a database that has three related tables. These tables show information about computer engineers. table one is engineers details table two is engineers allocated table three is jobs
My form needs to have buttons where a user can obtain information View details of all Engineers View Names of all the Engineers working on a specified job. Add a new engineer
I have set up the connection to the data base using the wizards and also made the dataset. How to handle retrieving the data from multiple tables. Here is a screen shot of my data set
I have Memberships and Bookings tables in database containing an attribute cust_id which is primary key in Memberships and reference key in Bookings. When i am executing data reader I want it to read cust_id values from membership table but it is reading it from the bookings table.....
I am combining data from multiple tables into one table for a presentation software. I am doing a select statement and running a loop. Inside that loop I have multiple selects and I build a datatable an enter the data into the main table. There is a ton of records and it takes forever.

I have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).
