More easy to understanding is that BLOB is string.

Let suppose you have Q : TQuery component, and its second field is BLOB.
You can manipulate with that field:

    ....
    Q.Fields[1].AsString:= := Memo1.Lines.Text;
    Q.Fields[1].AsString:= := Combobox1.Items.Text;
    ....
    Memo1.Lines.Text:=Q.Fields[1].AsString;
    Combobox1.Items.Text:=Q.Fields[1].AsString;

Best regards,
Igor.

The structure name BLOB comes from the acronym BLOB, which stands for "Binary Large OBject".

It's mean format of DB field where you can store arrays, images, texts and so on. But you can't make search by this field using SQL.
