SUR: Use DRDA's extended diagnostic to send ROW_UPDATED and ROW_DELETED
warnings.
---------------------------------------------------------------------------------
Key: DERBY-1313
URL: http://issues.apache.org/jira/browse/DERBY-1313
Project: Derby
Type: Bug
Components: JDBC
Reporter: Fernanda Pizzorno
Assigned to: Fernanda Pizzorno
Detectability of own changes is implemented in the client using warnings cf the
write-up for DERBY-775. When a row has been deleted and/or updated, a warning
will be sent to the client to indicate that fact. Presently, only one warning
can be sent each time a data row is sent from to the client, that means that
some warnings may be lost. Using extended diagnostic allows us to send several
warnings for each data row.
I propose to use extended diagnostics to send ROW_UPDATED and ROW_DELETED
warnings when necessary. This may later be extended for other warnings, but I
do not plan to do it as a part of the work in this issue.
