This Library does not Have a quick way to find foreign key references

[Keith1039]

Hello,

I was hoping to find a function that finds and returns a table or a list of foreign key relationships (table_name, referenced_column, referenced_table) but unfortunately such a function doesn't exist in this library.

I did some digging and found some SQL Server code that does that (works for Postgres too). The thread for this code can be found here
SELECT
KCU1.CONSTRAINT_SCHEMA AS FK_CONSTRAINT_SCHEMA,
KCU1.CONSTRAINT_NAME AS FK_CONSTRAINT_NAME,
KCU1.TABLE_SCHEMA AS FK_TABLE_SCHEMA,
KCU1.TABLE_NAME AS FK_TABLE_NAME,
KCU1.COLUMN_NAME AS FK_COLUMN_NAME,
KCU1.ORDINAL_POSITION AS FK_ORDINAL_POSITION,
KCU2.CONSTRAINT_SCHEMA AS REFERENCED_CONSTRAINT_SCHEMA,
KCU2.CONSTRAINT_NAME AS REFERENCED_CONSTRAINT_NAME,
KCU2.TABLE_SCHEMA AS REFERENCED_TABLE_SCHEMA,
KCU2.TABLE_NAME AS REFERENCED_TABLE_NAME,
KCU2.COLUMN_NAME AS REFERENCED_COLUMN_NAME,
KCU2.ORDINAL_POSITION AS REFERENCED_ORDINAL_POSITION
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS AS RC

INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS KCU1
ON KCU1.CONSTRAINT_CATALOG = RC.CONSTRAINT_CATALOG
AND KCU1.CONSTRAINT_SCHEMA = RC.CONSTRAINT_SCHEMA
AND KCU1.CONSTRAINT_NAME = RC.CONSTRAINT_NAME

INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS KCU2
ON KCU2.CONSTRAINT_CATALOG = RC.UNIQUE_CONSTRAINT_CATALOG
AND KCU2.CONSTRAINT_SCHEMA = RC.UNIQUE_CONSTRAINT_SCHEMA
AND KCU2.CONSTRAINT_NAME = RC.UNIQUE_CONSTRAINT_NAME
AND KCU2.ORDINAL_POSITION = KCU1.ORDINAL_POSITION
