HQL Query with fetch causes exception if no rows selected be query (java.sql.SQLException: Exhausted Resultset ) ---------------------------------------------------------------------------------------------------------------- Key: HHH-2293 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2293 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.2 Environment: Oracle 10g2 (10.2.0.2.0) Hiberbate 3.2.0 Reporter: Andriy Solonchuk After executing next query select p from ProductHibernate p left join FETCH p.productSomeCollection where 1=2 /* that will cause NO rows returned*/ we will have exception org.hibernate.exception.GenericJDBCException: could not perform sequential read of results (forward) at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103) ... Caused by: java.sql.SQLException: Exhausted Resultset at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) ... at org.hibernate.loader.Loader.getKeyFromResultSet(Loader.java:1088) at org.hibernate.loader.Loader.loadSequentialRowsForward(Loader.java:375) ... 24 more If we will review code of Loader.java class we can see next if ( resultSet.isAfterLast() ) { // don't even bother trying to read further return null; } if ( resultSet.isBeforeFirst() ) { resultSet.next(); } So at this step there are no checking if resultSet has any rows...
