Sequence within SQL Select

Question

I\'m having a bit of a problem with using my sequence within a SELECT statement.

SELECT
     c.cust_name,
     c.site,
     customer_id_seq.nextval

In a SELECT statement, you cannot specify NEXTVAL or CURRVAL in the following contexts:

• In the projection list when the DISTINCT keyword is used
• In the WHERE, GROUP BY, or ORDER BY clauses
• In a subquery
• When the UNION operator combines SELECT statements
