Question

I’m doing some FK analysis of our tables by making a directed graph representing FK dependencies and then traversing the graph. In my code, I name everything using directed graph terminology, but I’d like to have something a bit more ‘user friendly’ in the report.

In this scenario:

create table t1(a varchar2(20)); alter table t1 add constraint t1_fk foreign key(a) references t2(b); 

t1.a must exist in t2.b. So, what words should I use in the blanks?

t1 is the _______ of t2. t2 is the _______ of t1. 

Many TIA!

Answer 1

I’d say (things between brackets are optional, but I’d use them)

 [Column a of] table t1 references [column b of] table t2 

and

 [Column b of] table t2 is referenced by [column a of] table t1 

?

I’d also specify the action that happens on delete/update if any.

 Column b of table t2 is referenced by column a of table t1.  Deleting a record in table t2 will delete matching records on table t1
