findWithDynamicQuery

List findWithDynamicQuery(DynamicQuery dynamicQuery)
                          throws SystemException
Performs a dynamic query on the database and returns the matching rows.

Parameters:
dynamicQuery - the dynamic query to search with
Returns:
the matching rows
Throws:
SystemException - if a system exception occurred

findWithDynamicQuery

List findWithDynamicQuery(DynamicQuery dynamicQuery,

                          throws SystemException
Performs a dynamic query on the database and returns a range of the matching rows.

Useful when paginating results. Returns a maximum of end - start instances. start and end are not primary keys, they are indexes in the result set. Thus, 0 refers to the first result in the set. Setting both start and end to QueryUtil.ALL_POS will return the full result set.

Parameters:
dynamicQuery - the dynamic query to search with
start - the lower bound of the range of model instances to return
end - the upper bound of the range of model instances to return (not inclusive)
Returns:
the range of matching rows
Throws:
SystemException - if a system exception occurred

Typically not called directly, use local service update model methods instead. For example, UserLocalServiceUtil.updateUser( com.liferay.portal.model.User).

Parameters:
model - the model instance to update
merge - whether to merge the model instance with the current session. See BatchSession.update(com.liferay.portal.kernel.dao.orm.Session, BaseModel, boolean) for an explanation.

                              throws SystemException
Updates the model instance in the database or adds it if it does not yet exist, within a different service context. Also notifies the appropriate model listeners.

Parameters:
