This might be the same problem I've seen in MS Access when I do
something similar. I think the mysql "auto_is_null" option has a bug
where it zeroes the last_insert_id value. You insert a record, ODBC
does a "SELECT WHERE key IS NULL" behind your back, mysql zeroes
last_insert_id, you try to "SELECT last_insert_id()", and it returns
My fix has been to edit mysqld.cc and remove the AUTO_IS_NULL option
from thd_startup_options, but a better fix would probably be to remove
line 3047 from sql_select.cc (the "thd->insert_id(0);" line).
