how to update sql server from temporary table using visual basic net but don't create that temporary table on sql database (just in coding), the value of temporary table from ms-access table.
View 3 RepliesMy Scenario is that i have fetch data from one SQL Server table into vb.net DataTable.Now if any record is changed or New Record is saved into SQL Server Table i want to fetch or update only that record into my data table. is it possible.
View 1 RepliesI fill table data into dataset using Adapter. How to update dataset changes back to Microsoft SQL Server Table. I refer to the following URL, the solution is working fine, it makes use of the adapter.UPDATE to get table updated with changes made to dataset. [URL]
Sample Code:
cmdBuilder = New SqlCommandBuilder(adapter)
changes = ds.GetChanges()
If changes IsNot Nothing Then
adapter.Update(changes)
End If
I would like to know is there any other alternatives besides the one I have mentioned above. Can the alternative supports scenarios such as update existing record (probably based on primary key or defined conditions), insert new record as well delete existing record.

I am looking for the best way to edit and update the value of a database column that is defined as data type TEXT. You can't use a replace command in SQL and if I read in the value, update the data and update the record, the changes are not applied.
View 3 RepliesI have this code to edit the datarow of my table adapter but t doesnt update the table. I think i have a missing code that's why but i cant figured it out. by the way im using vb2008 and SQL as my database. [code]
View 3 RepliesI have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
An unhandled exception of type 'System.InvalidOperationException' occurred in system.windows.forms.dllerror in line: dbAdp.Update(dbDset) in btnSave_Click, (elseif editflag = true) blockdescription: Update unable to find TableMapping['Table'] or DataTable 'Table'I was also wondering if I could simply use the ExecuteNonQuery for the delete statement, but since I've placed my data in a datarow, I'm not sure if i can actually use it. Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

I am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;
Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click
[Code]...
This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.

in my every form i use update button to update values in a raw,
Now my query is that:- for doing so right now i have two option
1) UPDATE Table1 SET Column1 = Value1, Column2 = Value2 WHERE Some_Column = Some_Value but in this if i have many colom it will be a long process as in some table i have more than 50 coloms.
so i found a second option which is, first delete the row and then again insert the values but in this case it changes its row no which in some case not good for my project.
so i want to know is there any way to update * . or is there any short way to update similar to delete and insert.
I can pull 3 tables data into my program and read from all of them, I can update all 3 datasets but when it comes to updating the actual database i can only send the updates from the last dataset.

The above code is how I call the three tbls, the weird thing is that if I switch the order (savings with expenditure) then savings will be allowed to get updated and not expenditure.
I am working on a timekeeping application using Visual Basic 2008 Express and Access 2000.The database has two identical tables, each with 50 identical fields. Only the table names are different as are the input control names on the Windows form. The queries are also identical except for the query name and the reference to the table name in the "INSERT INTO" statement.
The sub procedure in Visual Basic for Week 1 works perfectly and inserts the record. The sub procedure for Week 2 runs through all commands and parameters but doesn't update the table.I have looked at every line of code, every parameter and every entry in the query and find nothing wrong. I run the query from within Access and it works fine.
Heres where I find an inconsistency that baffles me.the last lines of code in both sub procedures are:
objData.OpenConnection()
objData.Command.ExecuteNonQuery()
intRowsAffected = objData.Command.ExecuteNonQuery
[code]....
I set breakpoints at each line an the procedure that works stops at each of the six lines of code, the procedure that doesn't work gets to the 3rd line(in italics) and then exits the procedure with no error message and no indication as to why the record was not saved.
