Hi,
I am trying to use DataAdapter.Update to save a file stream into SQl Express.
I have a dialog box that lets user select the file:
openFileDialog1.ShowDialog();
I want to put
openFileDialog1.OpenFile();
Into
this.documentTableAdapter.Update(this.docControllerAlphaDBDataSet.Document.DocumentColumn);
I am thinking that it might just be some syntax issue, but I looked online, and didn't find much answers.
Thanks,
Ke
Hi, I am populating a datagrid with data from one sql table, I add additional columns and then wish to write it back out to another table. I have written the following code to acheive this, however it keeps throwing the follwing exception - "Update requites a valid UpdateComman when passed a DataRow collection with modified rows"
I've looked and I can see what the problem is, can anybody help please?

Hy, again! I am at the begining of an application. I have some modules that insert, delete and update only one row at one table. My question is should I use dataadapter.Update() or ExecuteNonQuery(). I prefer ExecuteNonQuery because I want to build a class : DataLayer to implement my own InsertProcedure(), UpdateProcedure(),DeleteProcedure(). I want speed in my application, so which is the best: dataadapter.Update() OR ExecuteNonQuery(). Thank you!
View 5 Replies View RelatedI am having trouble getting an Update call to actually update records. The select statement is a stored procedure which is uses inner joins to link to property tables. The update, insert, and delete commands were generated by Visual Studio and only affect the primary table. So, to provide a simple example, I have a customer table with UID, Name, and LanguageID and a seperate table with LanguageID and LanguageDescription. The stored procedure can be used to populate a datagrid with all results (this works). The stored procedure also populates an edit page with one UID (this works). After the edit is completed, I attempt to update the dataset, which only has one row at this time, which shows that it has been modified. The Update modifies 0 rows and raises no exceptions. Is this because the update, insert, and delete statements do not match up one-to-one with the dataset? If so, what are my choices?
View 1 Replies View RelatedHi,
I'm using DataAdapter.Update() to update data in a table. My question is; how do I create a trigger that works after the update has completely finished?
For example if my update adds 50 new rows to a table the trigger I've currently got fires after each new row that is added ie 50 times in total. Is it possible to get it to trigger after the last (ie 50th) row is added???
Thanks
Hi!
I am trying to insert data into 2 different tables. I am using dataadapter and dataset.

Call ConnectionString()
Dim insertSQL As New SqlCommand()
insertSQL.Connection = sqlConn

ndr("BuildingName") = BuildingNameTextBox.Text
ndr2("name") = RoomNameTextBox.Text
ndr2("FloorID") = FloorIDDDL.SelectedValue

da.Update(ds)

Catch ex As Exception

End Try
sqlConn.Close()
End Sub
The above code does not throw any error. It also does not update the tables.
Your help will be appreciated.
Thanks!

I am new to Sql, so I think this is a really easy question.
But I am working on a 2005 MSSQL database.
When I add columns to an existing application with data and tables already being used, and the new column will be set to Database Null.
What is an easy way to quickly add the data to all the rows in the table.
For example if I am adding a checkbox, I've been doing it manually, add the column, change all the rows to False, one by one.
And then I can change it to Disallow DBNull.
As I get more and more users this could be a very time consuming process.
So the name of the Table is classifeds_Ads and let's say the column I want to add is Bonus and it needs to be filled with False.
How do I do this???
Thank you in advance

Hi guys,I followed the ASP.net official tutorial to create a DAL & Business Logic Layer (http://www.asp.net/learn/dataaccess/tutorial02cs.aspx). I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing? I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method? Thanks for any help!!! 1 public bool AddDevice(string make, string model)
2 {
3 //cannot have the same device entered twice!
4 if (Adapter.FillDeviceCountByMakeModel(make, model) == 1)

Like the subject says, I'm using strongly typed datasets. I'm using to designer to create the datasets and the methods. I can select and insert, but I can't update or delete. I right click on the adapter bar and select Add Query. I sleect 'Use SQL Statements'I select 'Update' (or 'Delete')I get a sql statement pane containing the word 'Update' ('Delete') and asking 'What data should the table load?'I can click on next, but anything else gives me errors. I'd list them, but I'm clearly doing something wrong and it's probably obvious. Diane

I am using C# for ASP.NEt 2003.
I would like to know if there is any easy method to update a database with about 100 fields in it.
At present, I pass all the values of the controls on the web form to the stored procedure as parameters like :-
myCommand.Parameters.Add("@CustomerID", SqlDbType.Int).Value = txtCustomerID.text
Like this, I add all 100 parameters.
Is there any easy method to do it using a class or any other methods?

I have done some reading on the dataadapter class, but do not have a good handle on how to work with dataadapter after it has been filled by a dataset. For instance, should I use an if statement such as this to update the value in the dataadapter? if (dsSunbelt.Tables[0].Columns[39].Equals("")) { DataRow drUpdate = dsSunbelt.Tables[0].Columns[39].Equals(DateTime.Now); } I am sure it is not hard to see what I am doing, and I hope that I am missing something small, but how do I isolate a dataadapter value to update in the corresponding database?

Good day,
I just like to ask if anybody has experienced getting empty rows from SQL data adapter? I'm using SQL Server 2005. Problem is when the sql is run on Query Analyzer it retrieves a number of rows but when used in my application it returns 0 or empty rows.
I thought the connection is not the problem since I got my columns right. Below is my code snippet.
Thanks!
const string COMMAND_TEXT = @"select distinct somefield as matchcode, count(somefield) "
+ "as recordcount from filteredaccount where StateCode = 0 group by somefield having count(somefield) > 1";
SqlDataAdapter adapter = new SqlDataAdapter(COMMAND_TEXT, connection);
DataTable dt = new DataTable(sometablename);
adapter.Fill(dt);
For some reason I've had trouble with this today... can anyone provide me with a generic code snippet that programatically allows me to select data from a database limited by a parameter and then fills a datatable?
