Key: DERBY-619
URL: http://issues.apache.org/jira/browse/DERBY-619
Project: Derby
Type: Improvement
Reporter: Rick Hillegas
Right now we can push the following restriction fragment into the Store: "col <
CONSTANT". It would be good if we could also push "col1 < col2" into the Store.
Same goes for =, !=, >, etc..
