Subject Database schema within DB2
Date Mon, 27 Jan 2003 23:39:53 GMT

Well I'm most of the way to getting Torque to work with DB2 and my
generated OM classes (I think).  I am having a problem with Torque and DB2
schemas.

in my main application I have the following code

Torque.init("Torque.properties");  // in here I set up my default
connection to a DB2 database.

StepDefinition sd=new StepDefinition();  //This is one of my OM classes

sd.setCol1("asd");
sd.setCol2("kjdsf");
sd.save();


The save method throws the following exception


COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/6000] SQL0204N
"MYUSER.STEP_DEFINITION" is an undefined name.  SQLSTATE=42704

        at LTest.main(LTest.java:18)

the table MYUSER.STEP_DEFINITION does not exist but TEST.STEP_DEFINITON
does.  Torque is using the current default schema of DB2.  MYUSER is the
default because it is the userid I connect to the database with.

I have been able to get around this by changing my code to

Torque.init("Torque.properties");

Connection con=Torque.getConnection();
Statement s=con.createStatement();
s.execute("set current schema TEST");
StepDefinition sd=new StepDefinition();

sd.setCol1("asd");
sd.setCol2("kjdsf");
sd.save(con);
con.commit();


This is really messy though.  Am I missing something?  Is there a way to
set the schema within the Torque Framework?  Ideally there would be a way
to optionally define a default schema  in the Torque XML schema file and a
way to programmatically change this setting as the program is running.

Thanks In Advance

Dave
