As the question is about SQL… store it outside the video, in a separate column.

Of course, you can modify the video file and add some text there, but then it depends on many different factors: use of some video standard container, codecs for storing metadata, captions or something like that, compatibility.

If you still want to go this way, please see:

For manipulation with video files, I would strongly recommend open-source libraries and utilities FFmpeg or related libavcodec:

http://libav.org/[^].
