Question

I want to use a database like:

table wrongdoer (primarykey integer
ID, date)

table crime (numeric
foreign_key_to_wrongdoer, text crime)

I want my application (in python) to register a wrongdoer (which should give the entry a unique integer) and register the first crime against him. My idea is rather clumsy:

insert into wrongdoer(…)

id=cur.execute(“select max(ID)”)
//this is to select the most recent ID

cur.execute(“insert into
crime(‘”+id+”‘”crime+”‘”)”)

That is, insert an entry, select its unique key from DB (assuming its the highest number), and then use it for the subsequent queries. Is there a better way to do it?
