I have the necessity with a TIBSQL to retrive some TMemoFields and some
pictures stored in Interbase as TBlob. When I open the DataSet and with this
construct I want to retrive the memo I have an error. This is the
constructor:
MyBitMap := TBitMap.Create;
MyBitMap.Assign(TBlobfield(AIBSQL.Fields[0]));
How can I retrive a Blob field from a TIBSQL? |

var ms: TMemoryStream;
begin
ms := TMemoryStream.Create;
try
TBlobfield(AIBSQL.Fields[0]).SaveToStream(ms);
ms.Position := 0;
MyBitMap.LoadFromStream(ms);
finally
ms.Free;
end;
end;
