保存---------------------------
var
aStream1: TStream;
bmp : TBitmap;
begin
bmp := TBitmap.Create();
try
ADOTable1.append;
aStream1 := ADOTable1.CreateBlobStream(ADOTable1.FieldByName('photo'), bmReadWrite);
bmp.LoadFromFile('d:/My Documents/1212.bmp');
bmp.SaveToStream(aStream1);
// Image1.Picture.Assign(bmp);
aStream1.Free;
ADOTable1.Post;
ADOTable1.Next;
finally
bmp.Free;
end;
读取-------------------------------------
var
aStream1: TStream;
bmp: TBitmap;
begin
if ADOTAble1.State <>dsBrowse then exit;
if ADOTable1.FieldByName('photo').IsNull then Exit;

aStream1 := ADOTable1.CreateBlobStream(ADOTable1.FieldByName('photo'), bmRead);
try
aStream1.Position := 0;
bmp:= TBitmap.Create();
try
bmp.LoadFromStream(aStream1);
Image1.Picture.Assign(bmp);

finally
bmp.Free;
end;
finally
aStream1.Free;
end;
end;
