Database - Insert A DataTable With Existing Key To A SQL Server Table
Mar 18, 2010I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?
Insert Changed Data From One DataTable Into A Database Table In A Different DataSet
Oct 26, 2011I want to track changes in an application. So I've made a copy of the main table in that application, and am accessing both tables in the application using two separate datasets.
My plan was to use the HasChanges method of the main DataSet to get changed rows and then insert those into the copy table. When I run the code I get an error:
A first chance exception of type 'System.InvalidCastException' occurred in MyApp.exe
Unable to cast object of type 'MainDataTable' to type 'MainAuditDataTable'.
Here's the code:
If Me.DataSet3.HasChanges Then
' 'look for each row that has changes, not new rows
' 'insert that row into the auditing table

View 4 RepliesInsert GUID Into Datatable?
Jun 22, 2010I'm calling a GUID with a system function and trying to insert it into a database as a primary key. i'm using vb 2010 .net framework with sqlce server making my datatables. the column is AutoNumber which i set up to be a uniqueidentifier. the length is not adjustable and set at 16. i got all kinds of not parsing query errors. i've edited the insert statement a bunch trying to figure this out. i've went so far as changing the table schema of AutoNumber to be just a nvarchar with length of 100. it's something to do with how i'm inserting the GUID. in the code below i'm converting it into a string then inserting it into my table. is this wrong?? i've tried finding other ways of doing it but it's a little confusing. everything else in the code works perfectly it's just this part that is keeping me from completion.[code]...
View 2 RepliesUnable To Insert New Row Into DataTable
Feb 13, 2011I am fairly new to visual basic 2008 but not to visual basic(vb6). I want to insert a new row in the database table (library.mdb). I connected the database into my project and is bounded by a dataGridview control. I have no problem in getting the records from the database. I used the code under click event of a commandButton, after clicking the button neither the record inserts in the database table nor the program generates any error. The code I used is :
Dim bkrow As LibraryDataSet.Book_MasterRow
bkrow = LibraryDataSet.Book_Master.NewBook_MasterRow
With bkrow
.B_no = B_noTextBox.Text
.ISBN = ISBNTextBox.Text
[Code] .....
Here Book_Master is the database table. LibraryDataSet is the dataset, Book_MasterTableAdapter (not used in the above code) is the TableAdapter. Is there anything missing in the above code? Is there any other method to enter data into the database in visual basic 2008?

View 1 RepliesInsert An Entire DataTable Into A SQL Server At Once?
Oct 7, 2009I have a SQLClient.DataSet in VB.NET, and I want to insert the entire thing into a SQL Server table without having to do the following:
[Code]...
Since I've got close to a million rows (all pretty skinny, so it's not much space), I obviously don't want to run this loop and generate a million INSERT statements.
I know that one option is to use a linked server when I initially fetch the data, since it's coming from another SQL Server, and just have it to the INSERT from there. However, if I already have the data in my application, is there a more efficient way to bulk insert it? Can I somehow pass the DataTable as a parameter to SQL Server and have it sort it out and insert the rows?

Performing Insert And Update On A DataTable Using LINQ
Jul 12, 2011I am pretty new to using LINQ and have been trying it out querying my strongly typed DataTable.

Refering To DataTable Columns And DataRelations With INSERT..SELECT?
Dec 3, 2008There are plenty of SELECT (...) VALUES (...) statements and Parameters phrases to go with the VALUES. Those appear unhelpful to me as I have no form fields or datagrids and will be working with all the rows in a DataTable in a DataSet. Once started, this application will run to completion, writing as few as 10000 rows or as many as 250000 rows
My Task is to write out the contents of each specified DataColumn in the DataTable, one DataColumn at a time. The insert will also include the key columns and use the datetimestamp of the records as a criterion. Nulls in the specified columns are included.
My source is a DataTable, my target for the Insert is a "tall-skinny" table in an Access database. There is a smaller DataTable that is related to the source DataTable, if I was writing from within the AccDB I would use Joins. I have created a DataRelation, but have no idea how to use it in this context..
I have tried many different SQL statements but they all fail on Select. Here are snippets of the code:
'now, instantiate the specified DataTable from among the DataTables filled above
strDDTableNm = CStr(rsDDTblNms.Fields("Table_Name").Value)
Dim dtSrcTable As DataTable

View 2 RepliesAccessing A Database With A Datatable?
Mar 18, 2010I am currently working on a project for school. I have the project all laid out in my mind and everything but there is one thing that stops me. I can not access the data from the database itself ...
(detailed info)
I am using an AMD Athlon x64 bit processor with a windows vista 64 bit operating system. I am writing the program on visual basic 2008 express edition. When I open up the visual basic 2008 express edition and create a new project the first thing I do is go to the view menu and activate my database explorer. I connect to the database in question through the database explorer. The database I am connecting to is an access 2007 database (ive opened up the access 2007 files and they do open and display information properly, in otherwords, they do work) I then put in a listbox and use the following lines of code in a form load event to both A) create the datatable and B) automatically fill the listbox with the database info.
Dim dt As New DataTable()
Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=MEGACITIES.MDB"
[Code]....
When I test the program the listbox does not fill up with any information from the MEGACITIES access 2007 database. Ive tried connecting to the database by establishing a connection through the datasources window. Ive tried establishing a connection to the database through both the database explorer and data sources window. No matter what I try I can not get that information accessed.
Im almost confident that this has to do with my processor being 64 bit.
Populate A Datatable From A Database?
Dec 3, 2011I populate a datatable from a database. The table is sorted by the first column.

The new added rows are listed after the originally ordered rows and not in the right order.
Update Database From A Datatable?
Apr 5, 2011I need to make a small application in which I use a datagridview that is populated with data from a table from an SQL Server.In this datagridview I marked the checkbox for adding new rows, also for modifying values, etc So the user should be able to change values inside the datagridview and when the job is finished I have 'Save' button which should Updateall changes in database.For retreving data from the SQL server I use method
Me.Bedarf_tableTableAdapter.Fill(Me.ISB_CLDataSet.bedarf_table)
and for update I use:
Me.Bedarf_tableTableAdapter.Update(ISB_CLDataSet)
I have only one problem - When I clcik on the Save button I receive a message like this:Update requires a valid UpdateCommand when passed DataRow collection with modified rows.but only if I change values from existing rows. I am adding new rows the update method is working perfectly.
