Attaching derby-6959-01-aa-requireSETkeyword.diff. This patch makes the SET
keyword mandatory when altering the cycling behavior of an auto-increment
column. I am running the full tests now.

> Key: DERBY-6959
> URL: https://issues.apache.org/jira/browse/DERBY-6959
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.14.0.0
> Reporter: Rick Hillegas
> Assignee: Rick Hillegas
> Fix For: 10.14.0.0

> Attachments: derby-6959-01-aa-requireSETkeyword.diff,

>
> The correct syntax for changing the cycling behavior of an auto-increment
> column is...
> ALTER TABLE ALTER COLUMN $columnName SET [NO] CYCLE
> ...according to the 2016 SQL Standard, part 2, sections 11.20 (<alter
> identity column specification) and 11.72 (<sequence generator definition>).
> This is also the syntax used by DB2 (see
> https://www.ibm.com/support/knowledgecenter/en/SSEPEK_10.0.0/sqlref/src/tpc/db2z_sql_altertable.html).
> Right now Derby does not accept the required SET keyword. We should bring
> Derby into compliance with the Standard. I will attach a patch to do this.
