Client driver: Implicitly close exhausted result sets on the server
---------------------------------------------------------------------
Key: DERBY-821
URL: http://issues.apache.org/jira/browse/DERBY-821
Project: Derby
Type: Improvement
Components: Network Client, Network Server, Performance
Versions: 10.2.0.0
Reporter: Knut Anders Hatlen
Assigned to: Knut Anders Hatlen
Priority: Minor
Fix For: 10.2.0.0
Forward-only result sets that are exhausted should be implicitly
closed on the server. This way, ResultSet.close() does not have to
send an explicit close message generating unnecessary network traffic.
The DRDA protocol supports this. From the description of OPNQRY (open
query):
The qryclsimp parameter controls whether the target server
implicitly closes a non-scrollable query upon end of data (SQLSTATE
02000) in association with the cursor type.
