Delphi 10.4.1
UniDAC 7.2.5
Firebird 3.0.5

The error was in UniDAC in DBAccess.pas

For some reason, UsedConnection was not available in TCustomDADataSet.CreateBlobStream() when checking Oracle specific UsedConnection.ConvertEOL property.

I replaced the verification in line 10629 of DBAccess.pas

Code: Select all

if ... UsedConnection.ConvertEOL ... then

on the

Code: Select all

if ... ((UsedConnection <> nil) and UsedConnection.ConvertEOL) ... then

And it works for me.
