Kettering 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. If you know how, follow ISO-11179 data element naming conventions and formatting rules. Temporal data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect. 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.
