Subject Re: Problem with postgresql
Date Wed, 07 Jan 2004 08:48:41 GMT
I tried to follow your advises but still have the same problem.

Here is the situation right now:

1- In xml schema:
<database name="m3c" defaultIdMethod="native">
<table name="HOSPITAL" idMethod="native">
<column name="ID" required="true" autoIncrement="true" primaryKey="true" type="INTEGER"
<column name="NAME" required="true" size="30" type="VARCHAR" />
<id-method-parameter name="seqName" value="hospital_id_seq"/>

2- In Postgres i see that a sequence with the name "hospital_id_seq" is

3- In postgres the hospital table has following schema:
-- Table: public.hospital
CREATE TABLE public.hospital (
  id int4 DEFAULT nextval('public.hospital_id_seq'::text) NOT NULL, 
  name varchar(30) NOT NULL, 
  CONSTRAINT hospital_pkey PRIMARY KEY (id)

4- In HospitalMapBuilder.java there are following lines:
        TableMap tMap = dbMap.getTable("HOSPITAL");


        // this might need upgrading based on what all the databases
        // need, but for now assume one parameter.

The problem is when inserting, following exception happens:
org.apache.torque.TorqueException: IdGenerator for table 'HOSPITAL' is null
        at org.apache.torque.util.BasePeer.doInsert(BasePeer.java:708)

I appreicate any help to repair the problem.

The following is cut directly from a message I sent to this very list
only yesterday:

In your case this would be: hospital_hospital_id_seq
