[Manifold-l] Duplicating the GUI Explode Transform in SQL

I have a drawing containing single branch polylines. You can apply the
Explode transform from the GUI to split the polylines into their constituent
line segments.  I can also do this via a script by working on the pLine
objects but this is slow to execute on a large drawing.  SQL transforms
execute very fast in Manifold.  I would like to be able to script an SQL
clause that provides the same functionality as GUI  Explode.  I had been
experimenting  with the "Split By" clause and have looked at a number of
"split by" examples on GeoReference and Manifold-L but have not had much
success.  It thought I would turn to the Pros :)  Is there an SQL approach
to this problem?
