Hi,

when retrieving data from Oracle database a VARCHAR2 field being NULL gives an expections. When there is text in the field then the select works ok.

What might be the problem here and how can it be solved?

TIA,

Kari

ps. I did find some other post related to null values put not quite like this. Also, when can we expect the next release with the DevExpress wrapper among other enhancements :-)

Picture attached

We updated the debug mode in the version that I'm building to allow for the debugging of INSERT, UPDATE, and DELETE commands.  Before this version, the debug mode on the DbDataSourceItem class only showed SELECT commands.  So, once we get the new build to you, you can call SetDebugOn() on the DbDataSourceItem and you'll be able to see the command that is being sent to the database, and that will give us a clue.

The next release will be out before I leave the office today (4 hours or so to go)

Hi,

what might be the problem here: with the new relaese I still get the same ORA-00936 error mentioned in my previous post. Setting the debug on only shows the select statement - still the error appears when trying to save the changes.

Currently I'm testing this with the simplest possible query - just a couple of columns in the table. With SF samples everything is ok. Might the problem be with the SQL and Oracle? Unfortunately I didn't manage to find the right place to debug the application so that I could see the UPDATE statement.

Any ideas how to resolve this...?

Thank you for all your help,
Kari

Well, Kari, I'm not sure why the debug isn't working, but I'm building you a maintenance release right now that has some additional debugging information.  You can install this one and just leave it installed, don't worry about going back to the pre-release.

Once you get it installed, it should give you more information in the debug file.  Also, if you can get the version of Oracle that you're running, the table structure (screenshot or CREATE TABLE script would be fine), and the .Designer.vb file for the business object and post those with the output from the debug file, it will go a long way towards helping me to reproduce the error. 

Let me know Thanks

P.S.  I'll post the maintenance install here in a second.
