The SQL database contains a table with text.

                  To insert BLOB or memo data through SQL, the BLOB or memo data must be
                  passed as a parameter. On the Delphi side, the parameter must be of type
                  ftBlob or ftMemo, whichever is appropriate for the column type. The data to
                  be inserted must be in the form of a PChar buffer (or equivalent). Prior to
                  executing the query with the UPDATE or INSERT statement, fill the parameter
                  by assigning the PChar buffer to the parameter.

                    procedure TForm1.Button1Click(Sender: TObject);
                    var
                      P: PChar;
                      s: Integer;
                    begin
                      with Query1 do begin
                        ParamByName('StrParm').AsString := 'ABC';
                        s := Memo1.GetTextLen + 1;
                        P := AllocMem(s);
                        try
                          FillChar(P^, s, #0);
                          Memo1.GetTextBuf(P, s);
                          ParamByName('MemoParm').AsMemo := P;
                        finally
                          FreeMem(P, s);
                        end;
                        ExecSQL;
                      end;
                    end;

This is from me (Ronit):
The SQL statement should look like this:

SQL.Text:='insert into MyTable values("aaa","bbb"',:P)';
