Which table contains detailed information(For example the table the foreign key is referring to) about the constraints? The tables 'all_cons_columns' , 'all_constraints' contains only the name of the constraints which isn't very helpful. I am currently using dbms_metadata.get_ddl() but it doesn't work on all the databases.
Thanks.
It is all in there: the column R_CONSTRAINT_NAME in ALL_CONSTRAINTS contains the name of the referenced PK/UK constraint for a foreign key. You can then look up that constraint to get the TABLE_NAME of the reference table.
When looking at ALL_CONS_COLUMNS, the POSITION of the column in the foreign key will match the POSITION of the column in the primary/unique key.
