Insert An Entire DataTable Into A SQL Server At Once?

Oct 7, 2009

I 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?

Database - Insert A DataTable With Existing Key To A SQL Server Table

Mar 18, 2010

I 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?

VS 2005 - Print The Entire Datarow At A Time And Then Loop Through All The Rows Present In The Datatable?

Mar 26, 2010

I have created a datatable and now i need to print it,so i did the following:

Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage

Dim xPos As Single = 20

[CODE]...

The code works fine.But in the above code as you can see that i am printing the each rows content of the datatable one by one and after printing all the contents of a single row i am looping the code again for printing each and every row present in the datatable. So i want to know that inspite of printing each and every data present in the row of the datatable,is it possible to print the entire datarow at a time and then loop through all the rows present in the datatable?

Delete An Entire Record In Sql Server?

May 9, 2012

Got to say that i was struggling this code for saving data into another form in my program. so when this code saves data into desired db table, i would like to delete immediately from this db table once it saves data into the desired db table.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Using conn As New System.Data.SqlClient.SqlConnection("Data Source=MUSTAFAMUSTAFA;Initial Catalog=employment;User ID=sa;Password=123")

[Code]....

So form gets retreived data from another form then save it to another db table then, i want to delete what is appearing in the current form. i mean, the above code once it saves data, it then has to delete immediately.

For example, once i click confirm then saves it, then confirm button has to also delete it from this db table because i already moved the data.

Insert GUID Into Datatable?

Jun 22, 2010

I'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]...

Unable To Insert New Row Into DataTable

Feb 13, 2011

I 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?

Refering To DataTable Columns And DataRelations With INSERT..SELECT?

Dec 3, 2008

There 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

Catch DataTable RowChanging Event When Using TableAdapter.Insert Method

Apr 19, 2011

I setup a strongly typed dataset using the DatasetDesigner in VB2010. I am using the TableAdapter.Insert method to add data to an Access table. Before the data is inserted I need to validate the data using the DataTable RowChanging event.

How can I get the DataTable RowChanging event to fire when using the TableAdapter.Insert method?

Here is an excerpt of code I have so far:

When the Insert method runs, it does not fire the datatable RowChanging or NewRow events.

Insert Changed Data From One DataTable Into A Database Table In A Different DataSet

Oct 26, 2011

I 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

DB/Reporting :: SQL Server Data To DataTable?

I have been having trouble finding a good way to do this. Basically what I need to do is take a query from a SQL Server Database and place it into a DataTable (or an array) for manipulation. I've got the connection and everything working, but none of the methods I've tried so far seem to work very well.I need it to compare data with an uploaded CSV file and post on a website.

DataTable In SQL Server Compact Exception On First Fill ONLY?

Jun 5, 2011

I'm trying to create a Server/Client Sync scenario for my application using Sync Services for ADO.NET specifically the LocalCache custom tool which sets the whole thing up for me.My server DB has 5 Tables, all of which are being synchronized to the client application, which now has a SQL Server Compact DB with the same schema as the server DB. I have a dataset with some custom queries that I use to connect my app with the local database.So far so good.However in my application when I try to fill one of my tables with the table adapter on my form (the default "fill" method) it gives me the following exception:No mapping exists from DbType Object to a known SqlDbType.

However, if I continue and do the fill again, IT WORKS without a problem.
Try
Me.WTSUsersTableAdapter.Fill(Me.WTSMainDataSet.WTSUsers)

Run Query On In - Memory DataTable & Server Data

Jun 14, 2009

I wrote a procedure that builds a DataTable in memory using data stored on our DB2 database. The function builds a Multi-Level Bill of Materials (BoM), meaning that the data cannot simply be queried. The function works great and returns a nicely arranged DataTable object. However, I then need to query the in-memory DataTable against other tables on our server. What would be the best way to approach this problem? Should I make a DataTableAdapter for the Server tables and then build a DataView? I don't have too much experience yet with Data objects. (By the way, I looked into LINQ to DB2 and even installed IBM's addin's, but our server doesn't seem to support it at this time.)

Sql Server - Datatable.select With Byte Array?

Jul 16, 2009

I have populated a datatable from a SQL stored procedure and need to do further filtering on the datatable. The datatable holds data that is returned from the SQL DB as varbinary and is stored in the datatable as a byte array. I am attempting to pass TheData!Hash which is also a byte array.

When I need to filter the datatable I have use the following:

Dim sQuery0 As String = "Hash=" & TheData!Hash
Dim ResultRows As DataRow() = dt.Select(sQuery0)

I understand that the TheData!Hash is a byte array and cannot be converted to a string in this way but how on earth do I pass the byte array in the Select filter expression?

Datagridview Linked To A DataTable Loaded From A Sql Server Via An Adapter?

Apr 27, 2010

I have a datagridview linked to a dataTable loaded from a sql server via an adapter.I wish to sort one of the column: Filenumber.The Columns is a string. For example:

M-099
M-756
M-777
M-1000

But when i sort the columns by using Me.DataGrid.Sort(DataGrid.Columns(9), System.ComponentModel.ListSortDirection.Ascending), it turns out to be:

M-099
M-1000
M-756
M-777

I would like to know how to sort it like:

M-099
M-756
M-777
M-1000

How should i go about it? I've thought of getting rid of the M- in front and putting it into another column, but it makes filtering nuisance.Also, is it true the a custom sort via an IComparer is only applicable to things without a binding source?
