Database - OleDbCommandBuilder OleDbDataAdapter?
May 6, 2011
I have a field in a 2003 access database named first. I run the data adapter update command, gives me "Syntax error in UPDATE statement." I change the field name to firstName, try the update again, it works. I already have a bunch of programs using the database and using the field "first", do I really have to rename my field, go back and update all my programs to read from firstName instead of first? I really don't want to go that route if I don't have to. (provider=microsoft.jet.oledb.4.0)
*Edit: I meant to specify, I want the answer to use commandbuilder (but it won't work that way).

I have been working on this for a couple days now, and I am ready to throw my computer through the window.I am still rough around the edges with Visual Studio 2010.When I run the project, it works just as it should. the fields populate with the selected items from the .accdb, and I can navigate just fine up and down the rows. The problem comes when I try to update the info. When I change a value and hit the update button I get the following ERROR: System.Data.OleDb.OleDbException was unhandled Syntax error (missing operator) in query expression '((PID = ?)

I am trying to connect a VB.NET 2003 Oledbdataadapter through the wizard to a SQL Server 2005 Database, but i get an error message during the wizard.These are my steps:New Connection, Select provider (Microsoft OLE DB Provider for SQL Server), Select Connection:server name, log on: use windows NT integrated security, select database. I do all these steps then click "test connection" and it is fine, but when I click "ok" and error message pops up."Unable to connect to database. It is only possible to connect to SQL Server Desktop Engine databases and Microsoft Access Databases with this version of visual studio."

Is there an ODBC equivalent to OleDbCommandBuilder? I usually use the OleDbCommandBuilder to make changes to my database but one database I am using is Oracle.This is what I would normally do using an Access DB
f Me.planStatusCB.Text = "MATERIAL ORDERED" Then
Dim da2 As New OdbcDataAdapter("SELECT WORKORDER.WONUM, WORKORDER.STATUS FROM ORACLEDB.WORKORDER WHERE WORKORDER.WONUM=?", conn)

filling an OleDbDataAdapter.I have:
Dim cmd As OleDbCommand = New OleDbCommand(myQuery), myConnection)
Dim da As OleDbDataAdapter = New OleDbDataAdapter()
Dim dtDonnees As DataTable = New DataTable()
da.Fill(dtDonnees)
Filling takes too much time.For 20 lines it takes 20 seconds.And for 130 000 it takes a little more (but not 130 000 sec).But 20 seconds is too much anyway.
Question part 2: can I skip fill?I mean, after filling the datatable, I do a for each row of datatable and cast into an entities:
Dim returnList As New List(Of myObject)(dtDonnees.Rows.Count)
For Each rowDonnee As DataRow In dtDonnees.Rows
returnList.Add(New myObject(rowDonnee))'set every data of the row into my new object
Next
Can I pass each row of OleDbDataAdapter?

I am currently trying to create a search function on a page in VB.NET which will allow me to search a database for a customerID from a textbox called txtSearch and then present it into a datagrid.
So far I can display the customerID's manually by using
SELECT * FROM Customers WHERE CustomerID LIKE 'A%'
but cant figure out how to replace the A with data which will be inputted into the textbox.

I have had this headache for a few days now. Thought I had sorted it but haven't.I have copied worksheets from an excel workbook into a dataset, with each a datatable for each worksheet.
I then use a DataGridView to Display and edit the datatable.DataGridview.DataSource = MydataSet.DataTable(0) sort thing.But for some reason I just cant figure out how to write the datatable back to the excel worksheet.I have this but Im probably barking up the wrong tree.

I am using vb.net 2003. In my program I access an Access database file via Jet 4.0 and OleDbDataAdapter.I have several tables constructed with text boxes that are filled with data using OleDbDataAdapter.Fill. This all works fine. When Integer data is displayed in the boxes it is shifted to the left as text. How do I format these textboxes when I am filling them with the Fill statement? I would like them numbers to be shifted to the right and have commas placed every third didgit.

I need to update more than one DataAdapters, so I used the
Dim sqlcmdbldUser As New OleDbCommandBuilder(dtaadpUser)
Dim sqlcmdbldPoints As New OleDbCommandBuilder(dtaadpPoints)
But only one of them works, the second one brings up errors if I try to update the DataAdapter. Is there a way of using and updating multiple data adapters?

I've create a new VS 2008 Window Form Project using VB. I added an oleDbDataAdapter to the first and only form, set it to a table in my Access 2007 Database (there is only one table, PK field autonum of course and two Memo fields). The Database is in the Project's folder. A standard oleDb Connection object was created, as I expected, then I select the DataAdapter and choose 'Generate Dataset' which produces a standard DataSet called 'DataSet1.xsd'. Now when I build the project I get an error 'Error 1 Type 'FontTest.DataSet1' is not defined.' I do have a reference in my new Project to System.Data.So what the @#%$@ is going on? Why isn't the Dataset create by the DataAdapter being recongized? I can get into the DataSet Designer. The DataTable create is perfect, three columns defined correctly as I expected.

I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?

I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I'm trying to use LINQ to SQL in Visual Basic 2010 Express.
It allows me to create the .dbml file, but in order to drag items from the Database Explorer window to the design surface, I first have to get my database listed in the Database Explorer!(this is a remote SQL Server database - not a local .mdf)
I already have a good, working connection string to the remote SQL Server database, but that doesn't help me when I'm trying to generate the DBML at design time.
Can anyone tell me how to get my remote SQL Server database identified in the Database Explorere window? When I try the "Add Connection", I am limited to Access, SQL Server Compact, or SQL Server Database File. If I try to enter the IP address & port of my DB Host I get a 'database file does not exist' message. Doesn't seem to want to let me point to a remote DB server...

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.
