EAssertionFailed. Unknown data type (100)
Posted: Tue 21 Aug 2007 09:49
Hello,
I've been using version 2.5 for a without much problems, but it does not work with Windows Vista, so I decided to give the newest version a try.
So I installed the trial version and tried to get my application running. Which unfortunately didn't work
I made a simple test application and database table to test using Delphi 7 and SQL server 2005, both on my Windows XP pro development machine:
The Database table consists of 2 columns. The first is a uniqueidentifier column, the second an XML column.
The test application is nothing more then a SQLConnection, SQLDataSet, DataSetProvider, ClientDataSet, DataSource, DataGrid chain in a form and a button to open the connection.
When I try to open the ClientDataSet I get the following error:
EAssertionFailed with message 'Unknown data type (100)(D:\Projects\Delphi\Dbx\Source\dbexp.pas, line 2096)'
Is there a way to solve this?
