Find if a column in Oracle has a sequence

Question

I am attempting to figure out if a column in Oracle is populated from a sequence. My impression of how Oracle handles sequencing is that the sequence and column are separate en

Answer 1

If the sequence is used in a trigger, it is possible to find which tables it populates:

SQL> select t.table_name, d.referenced_name as sequence_name
  2  from   user_triggers t
  3         join user_dependencies d
  4         on d.name = t.trigger_name
  5  where  d.referenced_type = 'SEQUENCE'
  6  and    d.type = 'TRIGGER'
  7  /

TABLE_NAME                     SEQUENCE_NAME
------------------------------ ------------------------------
EMP                            EMPNO_SEQ

SQL>

You can vary this query to find stored procedures, etc that make use of the sequence.
