[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5229) org.hibernate.test.hql.ScrollableCollectionFetchingTest.testScrollingJoinFetchesEmptyResultSet() fails on sybase
[
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5229?page=c...
]
Gail Badner commented on HHH-5229:
----------------------------------
To determine if a ResultSet is empty, FetchingScrollableResultsImpl.isResultSetEmpty()
returns:
currentPosition == 0 && ! getResultSet().isBeforeFirst() && !
getResultSet().isAfterLast();
For Sybase ASE 15, when the ResultSet is empty,
FetchingScrollableResultsImpl.isResultSetEmpty() returns true. I've verified that
currentPosition is 0.
The problem is that Sybase JDBC returns true for ResultSet.isBeforeFirst() and/or
ResultSet.isAfterLast() when the ResultSet is empty.
org.hibernate.test.hql.ScrollableCollectionFetchingTest.testScrollingJoinFetchesEmptyResultSet()
fails on sybase

Result set is IDLE as you are not currently accessing a row.
Description: The application has called one of the ResultSet.getXXX column-data retrieval
methods, but there is no current row; the application has not called ResultSet.next(), or
ResultSet.next() returned "false" to indicate that there is no data.
Action: Check that rs.next() is set to "true" before calling rs.getXXX.
