[ http://issues.apache.org/jira/browse/DERBY-1490?page=all ]
Bryan Pendleton updated DERBY-1490:
-----------------------------------
Attachment: renameColumn_v5_with_schema_test.diff
Attachment renameColumn_v5_with_schema_test.diff differs from the
previous patch proposal only in the addition of a new test that demonstrates
that you can rename a column in a table in the non-current schema by
explicitly specifying a schema name.
That is, the proper syntax for the RENAME COLUMN statement is actually:
RENAME COLUMN [schema-name.]table-name.column-name TO new-column-name
Thanks Knut Anders for noticing this; I'll fix the documentation in the
DERBY-2042 patch.
> Provide ALTER TABLE RENAME COLUMN functionality
