DatabaseMetaData .locatorsUpdateCopy() should return true
---------------------------------------------------------
Key: DERBY-2789
URL: https://issues.apache.org/jira/browse/DERBY-2789
Project: Derby
Issue Type: Bug
Affects Versions: 10.2.2.0
Environment: Any
Reporter: Øystein Grøvlen
Assignee: Øystein Grøvlen
Fix For: 10.3.0.0
Since updates made to a BLOB or CLOB value in Derby is made on a copy,
DatabaseMetaData .locatorsUpdateCopy() call should return true. For the
embedded driver the functionality to update a LOB value is new in 10.3. For the
client driver, updates have been possible in prior releases, and
locatorsUpdateCopy() has returned false. That behavior was wrong since the
client updated a main-memory copy, not the values in the database. For 10.3,
the client will use a locator based implementation which will rely on the
behavior of the embedded driver. Hence, locatorsUpdateCopy() should return
true in both cases.
