C sqldataadapter rowupdating
You must explicitly set the commands before calling event and setting the Status to Skip Current Row. NVar Char, 15, "Category Name") Dim parameter As Sql Parameter = _ adapter.
Records that don't exist in the new CSV shouldn't be deleted, however.
I've been playing around the example from the MSDN library.
Update Command = new Sql Command( "UPDATE Temp Test Table SET Age = @Age, Name = @Name " "WHERE Temp Test Table Id = @Temp Test Table Id", connection); data Adpater.
Insert Command = new Sql Command( "INSERT INTO Temp Test Table (Age, Name) " "VALUES (@Age, @Name)", connection); Sql Parameter parameter = data Adpater.
Update(temp Test Table); Sql Data Adapter data Adpater = new Sql Data Adapter( "SELECT temptesttableid, Age, Name FROM Temp Test Table WHERE Name = @Name", connection); Data Table test Table = new Data Table(); // note that you should use an available csv-parser instead foreach (string line in File.
encounters a change to a Data Row, it uses the Insert Command, Update Command, or Delete Command to process the change. Rows(0) category Row("Category Name") = "New Beverages" adapter. Write Line("Rows after update.") Dim row As Data Row For Each row In category Table. Write Line(": ", row(0), row(1)) Next End Using End Sub either by returning the auto-increment value as an output parameter of a stored procedure and mapping that to a column in a table, by returning the auto-increment value in the first row of a result set returned by a stored procedure or SQL statement, or by using the are sent to the data source is important. Properties class Program Data Adapters and Data Readers Row States and Row Versions Accept Changes and Reject Changes Merging Data Set Contents Retrieving Identity or Autonumber Values ADO.I'm currently working on a program that allows for connections to multiple provider specific databases, so obviously I'm using the non-provider-specific classes (in System. Common) to work with these various connections once the connection or data adapter has been instantiated through the use of the provider's implementation. My main goal is to be able to handle those events through the use of the generic Db Data Adapter class, and it will be a big pain to have to cast things back to the derived classes of the provider-specific implementations for the data adapter. I did a lot of searching online, and really didn't find anything concrete besides just re-casting instances back to the derived classes to access those events. So, with the use of Extension Methods, I added two new methods to the Db Data Adapter abstract class that will allow the adding of event handlers for those two specific events, and here is my implementation (edited 4/23/2013 for handling of instance or static handler methods): I'm using the base Row Updated Event Args & Row Updating Event Args for the event arguments that get returned to the delegate, so if you need provider-specific members that are only available through the provider defined classes that are derived from the above two base event args classes, then they will need to be cast to those classes.
