This was confusing to me at first, also. There is no generic function to
create rows in two tables simultaneously. One simply creates the row in the
first table and then creates rows in the second table in a second step. The
"link" between the two tables is a single column that contains the same id.
See any of MANY online tutorials on SQL for an introduction or get a book on
SQL. I found that I had to sit and type verbatim from multiple sources
before I really understood what was going on, so you may want to try that.
Google for SQL tutorial for starters.
