Does update of database using a DataSet's dataadapter.update method cause single or multiple trips to database ?
When I change data in a dataset and then update database using dataset's dataadapter.update method, does the data get updated in one trip to database or multiple trips to database are involved in this update? There are multiple rows in the only datatable in a dataset.
I think it would involve multiple trips, and to be exact, it will involve as many trips to the database as there are changed rows in dataset's datatable. BUT NOT SURE.sun21170
According to the online help, you are correct:
When you call the Update method, the DataAdapter analyzes the changes that have been made and ex...DBError-Event in an Datawindow

The DataWindow control triggers its DBError event whenever there is an error

In my sql server database I am using the detailsview. All my database calls work perfectly (SELECT, INSERT, DELETE) except the update. The update command passes without error but does not change the values in the database. It recognises the new values and the old values but does not change the database values.
I am not doing eanything special but using the standard calls with the standard detailsview and everything else works.

I am quite new to PowerBuilder and databases so please bear with me...
We need our PowerBuilder application to write french characters to a
database and display them after retrieving from the database. We are using
PB7.0, but will be upgrading to PB8 soon. The database is Oracle 8.0.4. I
know that whatever support needed by Oracle is set-up properly because we
have another C++ application that writes to the same database and it
displays french characters with no problems.
I have tried setting the dbParm in the pb.ini file to include

Perhaps the application server is not connecting to the correct
database? What application server and database server are you using?
Is the select statement in the generated code by the DW DTC correct?

I have one question.

We have a developer who receives a GPF when the Update Event

This only happens on a specific datawindow on an Insert Row.

Open the datawindow painter and create a datawindow.
In your code, assign this to a datawindow control (or datastore object).
Set your transaction object. InsertRow(), SetItem(), Update().
You can build a datawindow object (part you did in the painter)

On a string column in a DW if I type in a special character
'=9c' and tab away from the field the '=9c' remains as
expected. If I put focus back to that column (autoselect
on) and type in 'o' and 'e' and tab out of the field, the
'=9c' reappears and no itemchanged event is triggered -- is
there anyway to handle this distinction of characters? What
is going on? I don't have any code in the ItemChanged
