[ http://issues.apache.org/jira/browse/DERBY-1491?page=all ]
Bryan Pendleton updated DERBY-1491:
-----------------------------------
Attachment: alterDefaultTests.diff
Proposed patch "alterDefaultTests.diff" is attached. This patch proposal
supercedes
the previous attachments. Note that this patch only includes new tests; the
current
product already supports the functionality to change a column's default value.
The
code to support this was a side effect of the DERBY-119 changes, which wired up
the already-existing parser routines to the new ALTER TABLE t ALTER COLUMN c
statement.
> Provide ALTER TABLE functionality to change a column's default value
