> Key: DERBY-6753
> URL: https://issues.apache.org/jira/browse/DERBY-6753
> Project: Derby
> Issue Type: Task
> Components: Documentation
> Affects Versions: 10.12.0.0
> Environment: Changes for DERBY-6742 will now make the newly generated
> value for a single row UPDATE statement available through
> IDENTITY_VAL_LOCAL(). Current documentation mentions only INSERT statement
> changing the value of IDENTITY_VAL_LOCAL(). The changes in the doc are very
> localized and from my search, the changes need to go only in the reference
> manual.
> Basically, DERBY-6414 now allows an identity column's value to be updated
> using DEFAULT clause in UPDATE statement(prior to DERBY-6414, there was no
> way of updating an identity column). This updated value is available through
> IDENTITY_VAL_LOCAL if only one row was updated of a table with identity
> column AND identity column was updated as part of that UPDATE with DEFAULT
> clause. The rules for UPDATE are same as for INSERT for IDENTITY_VAL_LOCAL.
> The rules for INSERT are already documented in the reference manual.
