I created the following .sql file to demonstrate a problem I'm having.

I have two tables that are related by keys. For instance,
Table employee {
last_name char(40) not null,
first_name char(40) not null,
department_name char(40) not null,
age int not null,
...
}
Employee table has a primary key (combination of last_name and first_name).

delete has two foreign keys that references two other tables and it is
also referenced by another table. But this...

Hello,
I think this will apply to alot of web applications:
users want the ability to delete a record in table x
this record is related to records in other tables

Hi,
Thought perhaps some other eyes than mine can tell if I'm doing
something wrong here or if there's a bug somewhere. I've never
passed a ROWTYPE varaible to a function but I don't see where

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
