trying to post a bmp file in blob oracle field i allways get this exception
Unknown ValueType = 31 (D:\Projects\Delphi\Dac\Source\MemData.pas, line 5693)
the code is

qrUQ.Edit;
DestStream := qrUQ.FieldByName(cBlob) As TBlobField;
DestStream.LoadFromFile('temp.bmp');
qrUQ.Post;
any idea?

This problem is not related to BLOB. It occurs if your query has a field of TIMESTAMP data type. We have fixed this problem. The fix will be included in the next build of UniDAC.
