If your intention is to Insert, Update, or Delete data, then you should consider using. If you query the OleDbDataReader's schema, you will see these additional. Hi there, i got problem here when i try to run the update query. The msg box the error is 'No value given for. Dim objread As OleDbDataReader.
Represents a set of data commands and a database connection that are used to fill the and update the data source.

Ok I have been reading up on the diffrence between OleDBDataAdapter and OleDBDataReader. I have been on MSDN library and they dont really explain the full diffrence. What I am looking for is which one is better for me. Link the db to the grid by SQL statement. And allow the user to edit/update/add/delete records. Everytime the user scrolls/click through the dbgrid the data will be displayed in textboxes below to allow data manipulation. I have tried to retreive info but I am unable to.
But I am able to connect to the DB. Don Jelley 16/2/2002, 18:34 น. Hi, is a deliberate attempt to encourage developers to use the disconnected model as disconnected data is more scalable because it reduces the demand on database servers. The DataSet is an in-memory cache of data retrieved from a database and process it in a DISCONNECTED fashion.
DataSets are the result of bringing together ADO and XML. A DataSet does not know about databases or SQL.
I recently bought the mass effect 2 digital deluxe edition on pc during the st. George's day sale however I haven't received any e-mails reguarding the cerberus activation code and i haven't found a way to contact ea customer services (the phone line is supposedly open 9am-9pm 7 days a week but is down at the moment) does anyone know if there's a contact e-mail or can help me sort this? This is also the reason why the Cerberus Network Code is not included as a seperate entitlement in the latest versions of the game. Please check if you do not already have the Cerberus Network Code activated in your game. Cerberus activation code.
There are two standard ways of getting tables of data into a DataSet, One is by using a 'OleDBDataAdapter' object that turns the results of a database query into XML. The second is to work directly Read and Write XML data and schemas, and can work closely with an XMLDataDocument object. The OleDbDataAdapter acts as an interface between the DataSet & the underlying databace for any data retrieval, updation, or deletion. OledbDataReader class offers higher performance than the DataSet class because OledbDataReader reads data directly from a database connection. There are two main situations where you would consider using DataReaders. If you use an application development model where you hand-code your user interface rather than use data binding, and hand-code your updates using SQL or stored procedures, then the DataReader provides an efficient tool for accessing relational data. For everyone else, DataReaders are useful where processing requires that you look up state held in a database, but you don't need scrolling, binding, XML or automatic updating capabilities.

- DataReader is more efficiant than DataSet because of lower overheads. - If you are developing application many times DataReader is a better choice. - However, if you are working with 'batch updates' kind of applications then DataSet is preferred.
- Windows clients can easily use disconnected behavior of DataSet as there are no issues of state maintenance. - In cases where you are passing data across tires, DataSet is recommended way.

But this one is faster when u need to access data only for read purpose.
Datareader maintains a constant connection with the database. Whereas, OLEDBDataAdapter is used when u want to work on the data like edit,insert,delete. Its more better as u have the flexibility/option to work on the data though its slow but its a lot useful, moreover it acts like disconnected recordset. Which one is better depends on your application & what u want.
