The following comment has been added to this issue:
Author: Marko Nikolic
Created: Mon, 1 Sep 2003 7:43 AM
Body:
Well, then 'Lightweight Class' should be removed from documentation ;) What is the way to do something similar? Maybe including blob column in select does not impact performance so much if you don't use Blob.getBinaryStream() on it? Is stream to blob opened when you issue select, or only when you ask for stream, or is that depending on jdbc driver implementation?

Now, loading FileInfo (lightweight) entity works fine. But if I try to load File (heavyweight) entity (after FileInfo was loaded and cached) with the same id as loaded FileInfo, using either:
session.load(File.class, id)
or
session.find("from com.redstarshop.data.File as c where c.id = ?", id, Hibernate.LONG)
I always get

The following comment has been added to this issue:
Author: David Channon
Created: Mon, 1 Sep 2003 1:14 AM
Body:
I cannot replicate this issue. I have added my tests for the dialect function enhancements back into the downloaded latest CVS src from v21branch. A simple new works fine and new using a join as described works fine. All other select parser tests pass fine as well. I have sent an email to Thilo to get extra information. In a few days, unless further info from Thilo demonstrates a defect, I would consider closing this JIRA report as 'unable to replicate' or whatever is appropriate.
Questions:
1) Should I test against other versions of the software.
2) Noticed CVS src not have my tests for the new Dialect functions included. Do you want me to submit the patch once again. I do think it should be included as a part of the basic SQL function test suite.
I will change the hsqldb dilect to include additional functions. This will allow the stock release system test runs to include testing the extended dialect functionality. This assumes the additional tests will be commited CVS.

Unfortunately, this patch works only for session.find, in order to make session.load work I guess that SessionImpl should be patched too.

Now, loading FileInfo (lightweight) entity works fine. But if I try to load File (heavyweight) entity (after FileInfo was loaded and cached) with the same id as loaded FileInfo, using either:
session.load(File.class, id)
or
session.find("from com.redstarshop.data.File as c where c.id = ?", id, Hibernate.LONG)
I always get

onLoad() may be used to initialize transient properties of the object from its persistent state. It may not be used to load dependent objects since the Session interface may not be invoked from inside this method.

Summary: Full feature support for connection pool DBCP

Assignee:
Reporter: Martin Schmidt
Created: Thu, 22 May 2003 3:57 AM
Updated: Sun, 31 Aug 2003 2:35 AM
Description:
The following patch extends Hibernate 1.2.5 to support all features of the Apache DBCP connection pool.
If a property is not specified, the default value from org.apache.commons.pool.impl.GenericObjectPool (connection pool) or org.apache.commons.pool.impl.GenericKeyedObjectPool (prepared statement cache) is taken.
Added configuration parameters to the hibernate.properties file:
# Connection pool
# Tests of connections
hibernate.dbcp.testOnBorrow
hibernate.dbcp.testOnReturn
# Eviction thread
hibernate.dbcp.timeBetweenEvictionRunsMillis
hibernate.dbcp.numTestsPerEvictionRun
hibernate.dbcp.minEvictableIdleTimeMillis
hibernate.dbcp.testWhileIdle
# -----------------------------------------------
# Prepared statement cache
# Tests of connections
hibernate.dbcp.ps.testOnBorrow
hibernate.dbcp.ps.testOnReturn
# Eviction thread
hibernate.dbcp.ps.timeBetweenEvictionRunsMillis
hibernate.dbcp.ps.numTestsPerEvictionRun
hibernate.dbcp.ps.minEvictableIdleTimeMillis
hibernate.dbcp.ps.testWhileIdle
--------------------------------------------------
Bug fixed:
Although it was possible to configure a validation query for the pool (in Hibernate 1.2.4), this query was never executed, because the DBCP properties "testOnBorrow" or "testOnReturn" were never enabled by the DBCPConnectionProvider.

Description:
I have multiple views that return different results, but all share a common structure
I have a class defined to represent one row from the view
I can map this class to the view and use a hibernate query to get a collection of objects
Now I want to be able to define the second query that returns data from the second view. It seems like I would need to be able to map the same class to a different view but I don't think that will be allowed in Hibernate.
For example:
Here's the common class mapped to the first view:
<class name="ResultSetRow"
table="VW_REQUESTS_MANAGER"
mutable="false">
<id name="reqId" column="req_id" type="long" unsaved-value="null">
<generator class="assigned"/>
</id>
<property name="name" column="name" type="string"/>
<property name="date" column="date" type="timestamp"/>
<property name="type" column="type" type="string"/>
</class>
and here's the Hibernate query that returns a collection of objects for each row returned by the view:
<query name="PendingRequests.ForManager">
from ResultSetRow as list
where list.managerId = :manager_id
</query>
The key issues are these:
1) The structure of each result set will always
be the same, only the contents will differ
2) A set of different database views will be created that share the same structure but return different content according to their purpose
3) I'd like to be able to share a common class instead of defining a different class for each different result set
4) I'd like to be able to create a set of mappings for each database view that returns the common class that defines the structure of the result set
Can I use a common class and map it to different table/views - or does the rule that one class maps to only one table prevent it ?
Thanks!

Description:
I have two classes Event and Person and I want to query event based on a Person. I was hoping I would be able to do this:
String query = "from com.rhi.domain.impl.Event as event where event.person =?"
Since Event is related to Person by a many-to-one relationship I thought Hibernate could create the right sql from the above query.
<many-to-one name="person" class="com.rhi.domain.impl.Person">
<meta attribute="property-type">com.rhi.domain.Person</meta>
<column name="person_id"/>
<column name="person_region_id"/>
</many-to-one>
But it didn't work and I had to do this:
String query = "from com.rhi.domain.impl.Event as event where event.personId = ? and event.personRegionId = ?";
and I also had to add separate mappings for the ids as such so that the query would work:
<property name="personId" column="person_id" type="java.lang.Long"/>
<property name="personRegionId" column="person_region_id" type="java.lang.Long"/>
I wasn't sure if this was a bug or a new feature. If this is a new feature are there plans to implement it?

Description:
At the begining, opensource Firebird (or FirebirdSQL) was based on the same source code of commercial InterBase. But during past three years, lots of improvements are done to the Firebird. Recent versions of these DBMSs have different features and statement syntaxes.
For example, their select offset/limit statement syntaxes are not compatible. Hibernate's recent InterbaseDialect select limit/offset feature is based on the Firebird's select statement syntax.
So, in order to prevent incompabilities and confussion, in addition to the InterbaseDialect, adding a new FirebirdDialect and seperating Firebird and InterBase features will be very helpfull.

q.setDouble("centX", x);
Iterator locs = q.iterate(); // Fails with QueryException
The final bit with 'centX' causes the problem, as the following query, with the 'centX' removed, succeeds:
Query q=session.createQuery("from Location loc where (loc.lonLat.UnitX between :minX and :maxX) order by ABS( loc.lonLat.UnitX )");
q.setDouble("minX", x - r);
q.setDouble("maxX", x + r);
Iterator locs = q.iterate(); // Succeeds
Also, using JDBC-style un-named parameters works:
Query q=session.createQuery("from Location loc where (loc.lonLat.UnitX between ? and ?) order by ABS( loc.lonLat.UnitX - ? )");
q.setDouble(0, x - r);
q.setDouble(1, x + r);
q.setDouble(2, x);
Iterator locs = q.iterate(); // Succeeds
Both of these two succeeding queries bring back all the results I would expect, with the correct ordering - so none of the function-calls or presence of a parameter in the order-by clause should be illegal.
The full stack trace is:
net.sf.hibernate.QueryException: Named parameter does not appear in Query: centX [from com.thisbedisonfire.madgag.persistence.Location loc where (loc.lonLat.UnitX between :minX and :maxX) order by ABS( loc.lonLat.UnitX - :centX )]
at net.sf.hibernate.hql.QueryTranslator.getNamedParameterLocs(QueryTranslator.java:437)
at net.sf.hibernate.hql.QueryTranslator.bindNamedParameters(QueryTranslator.java:817)
at net.sf.hibernate.loader.Loader.prepareQueryStatement(Loader.java:575)

at net.sf.hibernate.impl.QueryImpl.iterate(QueryImpl.java:29)
at com.thisbedisonfire.madgag.Main.main(Main.java:105)
So, something's going wrong with binding of named parameters...
Hope you can help!

This is why we do betas ;)
David, Its possible that this is a side effect of your changes to SelectParser ... at least you know the code, so would you take a look if you get a chance please. TIA.

Summary: Allow for Dialect specific seperator between schema and table name
Type: Patch
Status: Assigned
Priority: Trivial
Project: Hibernate2
Components:
core
Versions:
2.0.2
Assignee: Max Rydahl Andersen
Reporter: Chris Hane
Created: Thu, 10 Jul 2003 3:02 PM
Updated: Fri, 29 Aug 2003 11:27 AM
Description:
I'm on the receiving end of a Hibernate mapping file(s) that use the schema attributes. However, I am using MySQL which does not support schema (at least with the dot notation).
I added to Dialect:
getSchemaSeperator which will supply the default seperator found in Table (StringHelper.DOT).
In MySQLDialect I overrode this function to provide StringHelper.UNDERSCORE
I modified Table to use the new attribute from Dialect in getQualifiedName()
The source I modified was the latest (2003-07-10) pulled from CVS.

Comment:
I've attached a patch to correct OrderByParser, and updated FooBarTest.testNamedParams() to make a test for named parameters in the Order By clause.
I hope the patch is in the correct format - I'm currently in a windows-only environment, so I used the excellent win32 port of the GNU diff tool provided by http://unxutils.sourceforge.net/ . If there's a problem with the patch, please let me know and I'll re-diff it.

Description:
In a flight planning system. I got three entities, Staion, Leg and Movement. A Leg is a combination of a Departure and a Arrival. Departure and Arrival are subclasses of Movement. Movement has a relation to Station and holds a time.
Leg has one one-to-one relation with Arrival and one one-to-one relation with Departure.
Since hibernate force you to reuse the primary key in one-to-one relations tou can't setup above since Departue and Arrival shares the same table.
This is just one example when reuse of primary keys is annoying even worse is when you use composite primary keys.
