I cannot find a way to programatically:
1. Given a table name, find all foreign key fields in the given
table by field name (column name)
2. Given a single foreign key field name, programatically look up
the corresponding reference table name and the reference primary key field
so have thought of simply hard coding this (for 100 tables).
What Kind of data structure could I use that is available to me that
would hold as the key the table name and from there be able to iterate
through and get all foreign keys by field name and from there another
inner loop that would give me another key/value pair of the table name
(key) and the primary key (value) that corresponds to that foreign key?
I want to hard code all of this information into a data structure and
iterate through at some point in another function.
Instead of discovering this programatically, I can manually look at each
table / schema diagram and hard code it, but I really need one super
structure that will hold as keys every table in the schema and be able
to drill down that that tables foreign keys and from there further drill
down to get the table name, primary key field in that table.
I have seen a number of structures that might work, but cannot find an
example on how to actually use for what I need to do. If you do have an
idea of a structure, it would be great and awesome if I could be pointed
to an actual working example that I could test in a sandbox first to
understand how it works.
thanks
