Hi Gerhard,
working with Memo fields is somewhat tricky, because of some ADO.NET "features". Try to set the mapping info for your memo fields like that:
Unfortunately, ADO.NET needs a valid Size Property for the Parameter objects, so you have to provide a value, which is large enough for all possible cases. NDO passes the ColumnLength property as Size property to the Parameter objects.
On the other hand, the DDL (Data Definition Language) code for memo fields doesn't allow the definition of a column length. To avoid, that NDO inserts the ColumnLength value into the DDL, set IgnoreLengthInDDL to True.
That should work.
Best Regards:Mirko
