Hi Greg, Thanks for you reply! I've used views before within Torque. But in that case I've problems with inserts/update statements. How do you handle these? Regards, Robert -Original Message- From: Greg Monroe [mailto:[EMAIL PROTECTED] Sent: Friday, June 01, 2007 4:15 PM To: Apache Torque Users List Subject: RE: Joins and performance If this is a frequent/heavily used query, another way to deal with this is to create a view and a matching Torque object. There is a table option that suppresses the SQL generation. You can then just use the Peer/Record object as like it was a normal table. Note you may want to pay close attention to the indices requirements of the underlying table.

Joins and performance
Hi All, I've a question about joins. I've got 3 tables, namely: - Company - Company_building (Company has one ore more building) - Employees (Employee works in one ore more building) Getting all the companies will result in a low level SQL by Torque like: SELECT COMPANY.COMPANY_PK, COMPANY.COMPANY_NAME, COMPANY.COMPANY_FUNCTION FROMCOMPANY WHERE COMPANY.COMPANY_FUNCTION = 'SCHOOL' To get all the buildings I will loop through all the companies and call Company.getBuildings() this will result in: SELECT COMPANY_BUILDING.COMPANY_BUILDING_PK, COMPANY_BUILDING.BUILDING_NAME, COMPANY_BUILDING.COMPANY_FK FROMCOMPANY_BUILDING WHERE COMPANY_BUILDING.COMPANY_FK = 1 SELECT COMPANY_BUILDING.COMPANY_BUILDING_PK, COMPANY_BUILDING.BUILDING_NAME, COMPANY_BUILDING.COMPANY_FK FROMCOMPANY_BUILDING WHERE COMPANY_BUILDING.COMPANY_FK = 2 SELECT COMPANY_BUILDING.COMPANY_BUILDING_PK, COMPANY_BUILDING.BUILDING_NAME, COMPANY_BUILDING.COMPANY_FK FROMCOMPANY_BUILDING WHERE COMPANY_BUILDING.COMPANY_FK = 3 Etc. To get all the employees I will loop in Java through all the building and call CompanyBuilding.getEmployees() this will result in another lowlevel query. If I've 100 companies (which are schools) and 200 buildings, I will executes 100 * 200 queries to get all the employees. In low level SQL this query can be combined in one query. Is there a way to handle this within Torque? So I will get something like: SELECT * FROMCOMPANY, COMPANY_BUILDING, EMPLOYEES WHERE COMPANY.COMPANY_FUNCTION = 'SCHOOL' AND COMPANY_BUILDING.COMPANY_FK = COMPANY.COMPANY_PK AND EMPLOYEE.COMPANY_BUILDING_FK = COMPANY_BUILDING.COMPANY_BUILDING_PK I'm using Torque 3.1.1 (I will upgrade to the newest version very soon) Many Thanks!

Subject: RE: nullpointer BasePeer
Hi Robert,
the query looks ok to me. This is not the problem.
Hopefully you can debug your code. If yes, try to locate the static
initializer in your AdresPeer class. It is quite at the beginning and it
looks like the following
(with changed variable names,).
...
/** the column name for the NAME field */
public static final String NAME;
/** the column name for the VORNAME field */
public static final String VORNAME;
static
{
NAME = "benutzer.NAME";
VORNAME = "benutzer.VORNAME";
if (Torque.isInit())
...
Try to put a breakpoint into the first line into the "static { " block,
i.e. in my case the line "NAME = "benutzer.NAME";".
Do the same for one other class with which you have no problem (just to see
that the breakpoints work at tthat place)
Then put also a breakpoint at your doSelect statement.
Start your application and see whether the static initializer gets called
before the select.
If yes, debug into the following lines of the static initializer. There,
the Adres Map builder should be put into the dbMap.
Please mail back to the list with your findings.

RE: nullpointer BasePeer
Hi Thomas,
Thanks for your reaction and time! I've tried really a lot, also changed the
orderning of calling methods, but nothing solved the error. I still get the
NullPointer, cause the Adres table is not in the dbMap, while I try to sort
on it.
String package = 'nl.pagelink.torque.opm';
String table = 'OBJECTEN';
String column = 'NAAM_OBJECT';
String class = 'Objecten';
String value = "%drie%";
Criteria critiera = new Criteria();
Criterion criterion = criteria.getNewCriterion (table+"."+column, value,
criteriaObject.ILIKE);
criteria.add(criterion);
criteria.addJoin(ObjectenPeer.OBJECT_ID, ObjectAdresPeer.OBJECT_ID);
criteria.addJoin(ObjectAdresPeer.ADRES_ID, AdresPeer.ADRES_ID);
criteria.addAscendingOrderByColumn("ADRES.POSTCODE");
List objecten = ObjectenPeer.doSelect(criteria);
It result in the following query:
SELECT OBJECTEN.OBJECT_ID, OBJECTEN.NAAM_OBJECT,
OBJECTEN.X_COORDINAAT_ADRES, OBJECTEN.Y_COORDINAAT_ADRES,
OBJECTEN.Z_COORDINAAT_ADRES, UPPER(ADRES.ADRES_ID) FROM OBJECTEN,
OBJECT_ADRES, ADRES WHERE OBJECTEN.NAAM_OBJECT ILIKE '%drie%' AND
OBJECTEN.OBJECT_ID=OBJECT_ADRES.OBJECT_ID AND
OBJECT_ADRES.ADRES_ID=ADRES.ADRES_ID ORDER BY UPPER(ADRES.ADRES_ID) ASC
There are no columns of the joined tables in the query, is this correct?
Hopefully I forgot something ... perhaps do you have some new ideas?

Hi,
your problem is that you do not use the constants in the peer class to
create the link, but use String constants instead. For example, you use
criteria.addJoin("OBJECTEN.OBJECT_ID", "OBJECT_ADRES.OBJECT_ID");
instead of (hopefully I got the name of the constants right)
criteria.addJoin(ObjektenPeer.OBJECT_ID, ObjectAdresPeer.OBJECT_ID);
If you do not access a Peer class before executing a query which uses
information from this Peer, the problem occurs.

RE: nullpointer BasePeer
Hi Thomas,
Thanks for your reaction! I'm using Torque 3.1.1. I really don't know what
is going wrong.
I'm sure I added the adres into the schema.xml. When I change the order by
to the top table (on which the doSelect is executed), everything works fine
and I also get addresses in my result.
I've 3 tables which are involved in my example, namely
OBJECTEN (top)
OBJECT_ADRES (Mapping table which has a foreign key to Objecten and a
Foreign Key to Adres )
ADRES (Contains the order by)
String package = 'nl.pagelink.torque.opm';
String table = 'OBJECTEN';
String column = 'NAAM_OBJECT';
String class = 'Objecten';
String value = "%drie%";
String comparator = 'ILIKE';
Criteria critiera = new Criteria();
Criterion criterion = criteria.getNewCriterion (table+"."+column, value,
criteriaObject.ILIKE);
criteria.add(criterion);
criteria.addJoin("OBJECTEN.OBJECT_ID", "OBJECT_ADRES.OBJECT_ID");
criteria.addJoin("OBJECT_ADRES.ADRES_ID", "ADRES.ADRES_ID");
criteria.addAscendingOrderByColumn("ADRES.POSTCODE");
List objecten = ObjectenPeer.doSelect(criteria);

When I a print the dbMap before the error occurs, I see only the tables
ID_TABLE and OBJECTEN are stored in dbMap.
Because of the order by it needs to know the type of the column, but the
Adres table is not part of the dbMap.
Result -> NullPointer. Does anyone know why Adres is not in the dbMap? Is
something missing in the criteria?

Hi,
Is the table you want to use for joining (Adres) in your schema.xml ?
If not, you have to put it in there (this means you have to edit the db
scripts manually in order not to create and drop that table automatically,
but that is the price to pay)
If yes, which Torque version are you using and which is the exact code you

Hi all, I'm trying to do a query with an order by on a foreign table. A foreign table means another table than the one on which the doSelect is executed. By example: Get a person (PersonPeer executes the doSelect query) and order by Zipcode (Adres is the foreign orderby table) When i execute this i will get an error in BasePeer.java on line 1148: ColumnMap column = dbMap.getTable(table).getColumn(columnName); The adres table is not part a the dbMap (the Person table is part of it). Is this a bug, do I do something wrong or does anyone have a solution? Cheers, Robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Problem with Criteria After Deserializing
Hi,
Normally it's handled by JDK, I think by the Object class. I'm using RMI ...
so i'm also using serialisation. Comparing the toString() before and after
serialisation gave some differences. There where some problems with
serializing Hashtables and Uniquelists. Those where not handled by JDK.
That's why I wrote those extra methods.

Subject: RE: Problem with Criteria After Deserializing
Hi,
I do not have any experience with serialisation and deserialisation. I did
not find any custom serialize() and deserialize() methods in criteria, but
I thought the JDK handles this automatically. Ist that not true ?
By the way, I do not see the Criteria object as a long-lived object. They
tend to get modified in Queries, so I usually just throw them away after
they are used.

You need to compile without ant Use "maven torque" on the commandline. There's a maven tutarial op the torque website. Another idea is to copy the build file from the 3.1 version.

NullPointerException BasePeer within torque-3.1.1
Hi, When I try to add setIngnoreCase(true) within the following statement I get a NullPointerException in BasePeer.java. Criteria criteria = new Criteria(); criteria.setIngnoreCase(true); criteria.addJoin(ObjectsPeer.OBJECT_ID, Object2Peer.OBJECT_2_ID); Criteria.criterion criterion = criteria.getNewCriterion(Object2Peer.BOUWLAGEN, "%4%", Criteria.LIKE); criteria.add(criterion); objects = ObjectsPeer.doSelect(criteria); I did take a look in de the BasePeer.java. The NullPointerException is thrown because the table "OBJECT_2" is not part of the dbMap. When I print the contents of this Map I get the following result. - ID_TABLE - OBJECTEN OBJECT_2 is not part of it but I use it in my query. Because I set the ignore case it will check in the code if the column type is equal to String. Because OBJECT_2 is not part of the dbMap it cannot get the table description of OBJECT_2 and it it will throw a NullPointerException. Does anyone know how to solve it? Thanks for your time!
