Interface StatelessSession
- All Superinterfaces:
- java.io.Serializable
- public interface StatelessSession
- extends java.io.Serializable
A command-oriented API for performing bulk operations
against a database.
A stateless session does not implement a first-level cache nor
interact with any second-level cache, nor does it implement
transactional write-behind or automatic dirty checking, nor do
operations cascade to associated instances. Collections are
ignored by a stateless session. Operations performed via a
stateless session bypass Hibernate's event model and
interceptors. Stateless sessions are vulnerable to data
aliasing effects, due to the lack of a first-level cache.
For certain kinds of transactions, a stateless session may
perform slightly faster than a stateful session.
| Method Summary | |
Transaction |
beginTransaction()
Begin a Hibernate transaction. |
void |
close()
Close the stateless session and release the JDBC connection. |
java.sql.Connection |
connection()
Returns the current JDBC connection associated with this instance. If the session is using aggressive connection release (as in a CMT environment), it is the application's responsibility to close the connection returned by this call. |

Create a new Criteria instance, for the given entity name. |
Criteria |
createCriteria(java.lang.String entityName,

createQuery(java.lang.String queryString)
Create a new instance of Query for the given HQL query string. |
SQLQuery |
createSQLQuery(java.lang.String queryString)
Create a new instance of SQLQuery for the given SQL query string. |
void |
delete(java.lang.Object entity)
Delete a row. |
void |
delete(java.lang.String entityName,
java.lang.Object entity)
Delete a row. |
java.lang.Object |

java.io.Serializable id)
Retrieve a row. |
java.lang.Object |

java.io.Serializable id,
LockMode lockMode)
Retrieve a row, obtaining the specified lock mode. |
Query |
getNamedQuery(java.lang.String queryName)
Obtain an instance of Query for a named query string defined in the mapping file. |
Transaction |
getTransaction()
Get the current Hibernate transaction. |
java.io.Serializable |
insert(java.lang.Object entity)
Insert a row. |
java.io.Serializable |
insert(java.lang.String entityName,
