Log Message:
Simple recursion support for the SQL generator for
with $x seeded by expr recurse expr
SQL allows to express simple recursive statements using the
WITH RECURSIVE clause. In the core to algebra translation we
now have two recursion-strategies (for MIL and SQL) with different
behaviours.
The SQL variant, for example, cannot cope with non-DELTA evaluation
due to its inherent restrictions.
