[postmodern-devel] [S-SQL] Multiple rows in INSERT INTO clause

Is there some way in S-SQL to generate INSERT INTO clauses with multiple rows, e.g. "INSERT INTO "table" (a, b) VALUES (10, 20), (30, 40)" ? Desired sexp format is `(:insert-into table :set a (10 20) b (30 40)), transformation can work like a MAPCAR: stop processing values sequences as soon as the end of the shortest one is reached.

The reason to have such a feature is a performance issue: having a sequence of rows to be inserted we want to minimize the overhead related with sending queries to db; one query inserting, say, 50 rows is certainly faster than 50 queries each inserting 1 row.

I would prepare the patch myself, but the syntax of s-sql.lisp is a bit too tricky for me :(.
