Method Detail

executeUpdateback to summary
public int executeUpdate() throws HibernateException

Implements org.hibernate.Query.executeUpdate.

Doc from org.hibernate.Query.executeUpdate.

Execute the update or delete statement.

The semantics are compliant with the ejb3 Query.executeUpdate() method.
Returns:int

The number of entities updated or deleted.

getLockOptionsback to summary
public LockOptions getLockOptions()

Implements abstract org.hibernate.impl.AbstractQueryImpl.getLockOptions.

iterateback to summary
public Iterator<E> iterate() throws HibernateException

Implements org.hibernate.Query.iterate.

Doc from org.hibernate.Query.iterate.

Return the query results as an Iterator. If the query contains multiple results pre row, the results are returned in an instance of Object[].

Entities returned as results are initialized on demand. The first SQL query returns identifiers only.

Returns:Iterator<E>

the result iterator

listback to summary
public List<E> list() throws HibernateException

Implements org.hibernate.Query.list.

Doc from org.hibernate.Query.list.

Return the query results as a List. If the query contains multiple results pre row, the results are returned in an instance of Object[].

Returns:List<E>

the result list

scrollback to summary
public ScrollableResults scroll() throws HibernateException

Implements org.hibernate.Query.scroll.

Doc from org.hibernate.Query.scroll.

Return the query results as ScrollableResults. The scrollability of the returned results depends upon JDBC driver support for scrollable ResultSets.

Returns:ScrollableResults

the result iterator

scrollback to summary
public ScrollableResults scroll(ScrollMode scrollMode) throws HibernateException

Implements org.hibernate.Query.scroll.

Doc from org.hibernate.Query.scroll.

Return the query results as ScrollableResults. The scrollability of the returned results depends upon JDBC driver support for scrollable ResultSets.

Returns:ScrollableResults

the result iterator

setLockModeback to summary
public Query setLockMode(String alias, LockMode lockMode)

Implements org.hibernate.Query.setLockMode.

Doc from org.hibernate.Query.setLockMode.

Set the lockmode for the objects idententified by the given alias that appears in the FROM clause.

Parameters
alias:String

a query alias, or this for a collection filter

setLockOptionsback to summary
public Query setLockOptions(LockOptions lockOption)

Implements org.hibernate.Query.setLockOptions.

Doc from org.hibernate.Query.setLockOptions.

Set the lock options for the objects idententified by the given alias that appears in the FROM clause.
