DataSource Controls :: DataAdapter Update Method?
Feb 19, 2010i am having a datatable with 10 rows.
Out of this 10 rows 3 Rows have their RowState as Added, 2 rows as Modified, and 4 as Deleted.
Now i want to use Datadapter's InsertCommand, UpdateCommand and DeleteCommand
Is it possible to update datatable's changes to Database with Single DataAdpater.Update(DataTable) Call.
Means i will call DataAdapter.Update(DataTable) method only once and with this all new added rows should be inserted in database, modified rows should be updated and deleted rows should be deleted from Database.
Forms Data Controls :: Update One Or Two Columns In A Table Without Using Dataadapter / Dataset?
Mar 14, 20101. As per my knowledge we use dataadapters/dataset when we want to deal with the huge amount of column/data. Is there anyway that if I want to update one or two columns in a table without using dataadapter/dataset?
2. There is a way that without clicking a button we can get the data using objectdatasource, I mean to say that there is no vb.net data in the code behind then how to debug if there is not data in vb.net in code behind.

What's The Difference Between A DataSource And DataAdapter
May 6, 2010Title says it all. What is the difference between a DataSource and DataAdapter? I'm trying to decide if I should descend from IDataSource or IDataAdapter for code to be shared between Winforms and WebForms and I can't seem to figure out what the difference is other than slightly different ways to use them.

DataSource Controls :: Reset Identity Column To A New Value?
Jan 16, 2010Resetting IDENTITY column to a new valueDuring application development we always entry some test data also our tester test with test data and as a result if the table contains IDENTITY columns( specially ID column) which incremented to the number of data already entered.
However, when the application goes running with real data to the client and the client want his ID values from starting 1, then we need to RESEED the value of the IDENTITY column of the table after clearing all data. This can be done as bellows:
DBCC CHECKIDENT (TableName, RESEED, 0)
However, can be reseed with any values instead of zero(0) in the above statement.

DataSource Controls :: Use Of Scope_identity(), @@identity And Ident_current?
Jan 19, 2010I'm trying to insert data into two tables that are related within a store procedure. After the first insert I want to get the id of the inserted row to use as a parameter during the insertion of data in the other table. I'm sure this is a common task, and I have looked into things like scope_identity(), @@identity and ident_current. However I'm not sure exactly how to use the id as a parameter.My attempt now looks like:
DECLARE @RETURN_VALUE
INSERT INTO Table1(test_name) VALUES ('asdf')
@RETURN_VALUE = SCOPE_IDENTITY()
INSERT INTO Table2(test_name) VALUES(@RETURN_VALUE)

DataSource Controls :: Finding Function That Grabs The Inserted Identity Value?
Jan 11, 2010I have a detailsView that I use for Insert. Once a record is Inserted, I need to get the new idenetity value.
Is there some function that grabs the inserted identity value? Or do I need to query it somehow?
By the way, the reason I'm doing this is the user is inserting a record into a 'general' list that is being applied to a 'specific' list - example, an employee can select a vendor from a list, but the vendor isn't listed so the employee adds the vendor in the vedor list and while the new vendor is inserted, the vendor info is also applied to the new order record.
DataSource Controls :: Use Scope Identity To Get Newly Inserted Table
Feb 14, 2010I have an SQL Server table named "Fields" with an autoincrement identity column "FieldID" as the primary key, an nchar column "Phrase" that textbox entries are to be stored in from a web page, and another column that is defaulted to null. The following is the recommended example on how to use Scope_Identity() to get a newly inserted table row identity value:
//C#
string query = "Insert Into Categories (CategoryName) Values (@CategoryName);" +
"Select Scope_Identity()";
int ID;
string connect = @"Server=.SQLExpress;AttachDbFilename=|DataDirectory|Northwind.mdf;" +
"Database=Northwind;Trusted_Connection=Yes;";
using (SqlConnection conn = new SqlConnection(connect))
{
using (SqlCommand cmd = new SqlCommand(query, conn))
{
cmd.Parameters.AddWithValue("@CategoryName", Category.Text);
conn.Open();
ID = (int)cmd.ExecuteScalar();
}
}
Obviously, this example uses a Categories Table in a Northwind database, which I do not have. So I am confused by how to adapt this example for my application. The following is my data context:
DataClassesDataContext db = new DataClassesDataContext();
Could you explain how I can adapt the example for my "Fields" table in my "EFMDB" database?
