用ZLib压缩TStringList并保存到SQL VARBINARY列

uses
  ZLib;

procedure CompressAndSaveToDatabase(list: TStringList);
var
  compressedData: TMemoryStream;
  zlibStream: TCompressionStream;
  byteArray: TBytes;
begin
  // Convert TStringList to byte array
  byteArray := TEncoding.UTF8.GetBytes(list.Text);

  // Compress the data
  compressedData := TMemoryStream.Create;
  try
    zlibStream := TCompressionStream.Create(clDefault, compressedData);
    try
      zlibStream.Write(byteArray[0], Length(byteArray));
    finally
      zlibStream.Free;
    end;

    // Save the compressed data to SQL VARBINARY column
    // Save compressedData to the database using appropriate SQL statements
    // ...

  finally
    compressedData.Free;
  end;
end;
