Please post DDL, so that people do not have to guess what the keys,
constraints, Declarative Referential Integrity, data types, etc. in
your schema are. Sample data is also a good idea, along with clear
specifications. It is very hard to debug code when you do not let us
see it.

Also data element names like "id" (of what entity?) and time (a
reserved word in SQL) are pretty useless. I am sure that 'A' is a
meaningful name in your industry ...
