ORA-02289: sequence does not exist

I've inherited another developer's code and this query:

select id_seq.nextval from dual

Is causing this error:

ORA-02289: sequence does not exist
02289. 00000 -  "sequence does not exist"
*Cause:    The specified sequence does not exist, or the user does
           not have the required privilege to perform this operation.
*Action:   Make sure the sequence name is correct, and that you have
           the right to perform the desired operation on this sequence.
Error at Line: 1 Column: 7

I'm pretty sure the user has the required privileges to run this query. How can I fix this?

3 possibilities

the sequence really does not exist   - check dba_sequences
the user you are using doesn't have privileges   -check dba_tab_privs
a synonym pointing to the sequence doesn't exist  - check dba_synonyms

it must be at least 1 of those 3.

When looking for existence, check for misspellings including possible case sensitivity.

For example did somebody create the sequence as "id_seq"  instead of id_seq?

Thanks, do I need to use a system user to access and view these dba_sequences, dba_tab_privs, and dba_synonyms tables?

you will need to have privileges to read those,  doesn't necessarily mean SYSTEM or other DBA users though.

you can try using the "ALL_" versions instead of "DBA_" versions of the views, but, those are based on permissions.  So, if you don't have permission to read the object then you won't see them in the ALL_ views either, thus giving a false-negative.

If you don't have permission yourself, ask have to ask your DBA or another privileged user to do it for you.

The sequence didn't exist on this database yet. DBA migrated them over now and all is good.

Thanks for your help.
