Subject [jira] Created: (DERBY-4803) Sequences do not work in INSERT/SELECT
Date Thu, 16 Sep 2010 19:59:34 GMT
Sequences do not work in INSERT/SELECT
--------------------------------------

                 Key: DERBY-4803
                 URL: https://issues.apache.org/jira/browse/DERBY-4803
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.6.1.0
         Environment: Mac OS X, Derby Network Server 10.6.1.0
            Reporter: DK


Using sequence in SELECT works fine whereas the same SELECT query used in INSERT/SELECT results
in "The statement references the following sequence more than once" error. This happens even
though the SELECT in question returns exactly 1 row of data.

The Reference Manual states 1. " NEXT VALUE FOR expression may occur in the following places:
SELECT statement: As part of the expression defining a returned column in a SELECT list" and
2. " NEXT VALUE expression may not appear in any of these situations: CASE expression, WHERE
clause, 
ORDER BY clause, Aggregate expression, ROW_NUMBER function, DISTINCT select list".
Nowhere a restriction on INSERT/SELECT is mentioned. Additionally, other databases (i.e. Oracle)
support use of sequences in INSERT/SELECT.

Therefore, I consider it a bug.
