Setting not null EJB relationships
I have a table with a one to one relation to another table through a foreign key. The foreign key is a not null column. OC4J won't let me set the relationship in ejbCreate, but because the field is not null I can't set it in ejbPostCreate. Do I have any options besides making the column accept null values?
You have two options.
Option: 1
Declare the not null constraint as deferrable; the constraint are checked only when the data is committed
Option 2:
In the Entity Bean, you have to add an addition cmp-field ( customerid) for the FK in addition to the existing CMR ( altered ejb-jar.xml & orion-ejb-jar).
You have to set the customerid in the ejbCreate segment & set up the relationship in the ejbPostCreate section.

When I try to create an EJB with an CMR field passed on the ejbCreate I have two options:
1. set the CRM in ejbCreate (setXXX method): not posible, illegal state (ok by EJB 2.0 specifications)
2. set the CMR in ejbPostCreate (setXXX method): not posible - after ejbCreate the container tries to make the insert and gets the "unable to insert null into XXX" because the id of the CMR must be set NOT NULL in the database.
On bea there is something like delay-insert-until ejbCreate or ejbPostCreate.
What are my options on oc4j 9.0.3?I will state the obvious, but nevertheless, have you restarted the j2ee engine?

How can I set my WebI filters to Null and not Null
Folks,
I have created a report in WebI and now I am to set up some filters as Null and some Not Null.
How can I set my WebI filters to Null and not Null?
Regards,
Bashir AwanHi,
As you said you could do it at the report level and also at the universe level.
One more way is to create the filters in the universe levele and add them in thequery filter.
Ex: in the filter you need to write :
Column1 is null and and column 2 is not null etc.
Hope this will help.
If this did't solve your problem then please explain it in detail.
Cheers,

From the error message, this issue seem to related with SSL/TLS connection. So I go back to check configuration and find out a difference to tutorial. Current SCP url is https://server1/_wmcs/certification, but in tutorial it is https://server1:433/_wmcs/certification.
On my opinion, I don't think it is the real reason.
So, how can I resolve this error? Could you give me some suggestion? Thanks in advance.

How to set ResultSet not null?
Hello !
How can I set my ResultSet null? rs.next( ) is null.
Thanks in advance."...Hey, do you guys have an idea how to apply operator to method getTime() e.g rs.getTime("TimeOut") - rs.getTime("TimeIn")?..."
It can't be done.
One thing you should be checking is whether or not the last value returned from the result set was null, using the wasNull() method.
If you're getting a NPE, it could be that one of the values you think you're getting back from the database is really null.
Are you sure you want java.sql.Time? Not java.sql.Timestamp?
Code it like this:
java.sql.Timestamp timeIn = rs.getTimestamp("TimeIn");
java.sql.Timestamp.timeOut = rs.getTimestamp("TimeOut");
long duration = 0L;
if ((timeIn != null) && (timeOut != null))
long millisecondsIn = timeIn.getTime();
long millisecondsOut = timeOut.getTime();
duration = millisecondsOut - millisecondsIn;
assert (duration >= 0L);

In evaluating the latest release of JDeveloper (9.0.3), I have noticed that the CMP EJB wizard does not produce compilable code when generating default relationships. It appears that the set methods for the PrimaryKey and ID values are not generated properly. I guess I have to create those methods manually.
Is this the way JDev is supposed to work ?
I have not found any information in the JDeveloper docs that cover this issue. Any help would be appreciated.
TIA.
Steve Guilford...>>>Steve-
Can you describe what is wrong with the CMR setters? Are you working with basic (single column) or compound (multi-column) primary/foreign keys?
There may be some issues lurking when using multi-column PK's, particularly if the PK includes a foreign key (if represented by a CMR field), but in some cases these are caused by an invalid CMR condition (such as a non-deferred NOT NULL constraint on a FK column -- the EJB spec implicitly prevents this condition).
If you can send me your schema or codegen details, I'll be happy to take a look.

Default Value , Not Null and EJB2.1
Hi ,
Am using Weblogic10.3 + Oracle Db + EJB2.1 Local Entity Beans .
The issue is that one of the table has createdDt which is not null and is defualt is set to Sysdate. When I try to create this Entity with createdDt null , I get an exception like below , But since I have mentioned default value , I shouldnt be getting this. Have I missed something ?
Code is quite straighforward

In addition to solutions offered by SwapnilVJ and Saransoft84, you could also use a rest parameter:
function parmTest(... args)
// set up default values
var val1:Boolean=true;
var val2:String="";
switch(args.length)
case 0:break;
case 1:
if(args[0] is String){val2=args[0] as String;}
else{val1=args[0] as Boolean;}
break;
case 2:
default:
val1=args[0] as Boolean;
val2=args[1] as String;
break;
trace(val1 + " " +val2);
parmTest();
parmTest("hello");
parmTest(null,"hello");
parmTest("hello",null); -
When primary table is also join table and you have NOT NULL constraints
Hi,
Me again. This is similar to the message titled "Problem with an
optional 1 to 1 relationship modelled using a link table". Whats
different about this case is we are dealing with a one to many relationship.
Given this SQL:
create table person (
pid INTEGER(10) NOT NULL,
language_code VARCHAR(3) NOT NULL
create table language_person (
pid INTEGER(10) NOT NULL REFERENCES person(pid),
language_code VARCHAR(3) NOT NULL,
first_name VARCHAR(20) NOT NULL
I wrote these classes (abbreviated)
Person:
* @jdo:persist
* @jdo:identity-type application
* @jdo:objectid-class PersonId
* @jdo:requires-extent false
* @jdo:extension vendor-name="kodo" key="table"
* value="PERSON"
* @jdo:extension vendor-name="kodo" key="lock-column"
* value="none"
* @jdo:extension vendor-name="kodo" key="class-column"
* value="none"
public class Person {
* @jdo:primary-key true
* @jdo:extension vendor-name="kodo" key="data-column"
* value="PID"
private int pid;
* @jdo:extension vendor-name="kodo" key="data-column"
* value="LANGUAGE_CODE"
private String languageCode;
* @jdo:collection element-type="LanguagePerson"
* @jdo:extension vendor-name="kodo" key="pid-data-column"
* value="PID"
* @jdo:extension vendor-name="kodo" key="table"
* value="LANGUAGE_PERSON"
* @jdo:extension vendor-name="kodo" key="pid-ref-column"
* value="PID"
* @jdo:extension vendor-name="kodo"
key="languageCode-data-column"
* value="LANGUAGE_CODE"
* @jdo:extension vendor-name="kodo"
key="languageCode-ref-column"
* value="LANGUAGE_CODE"
private Set languagePersons = new HashSet();
public Person(int pid, String languageCode) {
this.pid = pid;
this.languageCode = languageCode;
public void addLanguagePerson(LanguagePerson languagePerson) {
languagePersons.add(languagePerson);
public Set getLanguagePersons() {
return languagePersons;
LANGUAGE_PERSON
* @jdo:persist
* @jdo:identity-type application
* @jdo:objectid-class LanguagePersonId
* @jdo:requires-extent false
* @jdo:extension vendor-name="kodo" key="table"
* value="LANGUAGE_PERSON"
* @jdo:extension vendor-name="kodo" key="lock-column"
* value="none"
* @jdo:extension vendor-name="kodo" key="class-column"
* value="none"
public class LanguagePerson {
* @jdo:primary-key true
* @jdo:extension vendor-name="kodo" key="data-column"
* value="PID"
private int pid;
* @jdo:primary-key true
* @jdo:extension vendor-name="kodo" key="data-column"
* value="LANGUAGE_CODE"
private String languageCode;
* @jdo:extension vendor-name="kodo" key="data-column"
* value="FIRST_NAME"
private String firstName;
public LanguagePerson(int pid, String languageCode, String firstName) {
this.pid = pid;
this.languageCode = languageCode;
this.firstName = firstName;
And then I do this:
PersistenceManager pm = JDOFactory.getPersistenceManager();
pm.currentTransaction().begin();
final Person person = new Person(1,"EN");
final LanguagePerson languagePerson = new
LanguagePerson(1,"EN","Mike");
person.addLanguagePerson(languagePerson);
pm.makePersistent(person);
pm.currentTransaction().commit();
The SQL that issues forth is this:
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
preparing statement <17089909>: INSERT INTO PERSON(LANGUAGE_CODE, PID)
VALUES (?, ?)
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
executing statement <17089909>: [reused=1;params={(String)EN,(int)1}]
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
preparing statement <9818046>: INSERT INTO
LANGUAGE_PERSON(LANGUAGE_CODE, PID) VALUES (?, ?)
1125 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
executing statement <9818046>: [reused=1;params={(String)EN,(int)1}]
1140 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
preparing statement <24763620>: INSERT INTO LANGUAGE_PERSON(FIRST_NAME,
LANGUAGE_CODE, PID) VALUES (?, ?, ?)
1140 [main] INFO jdbc.SQL - [ C:6588476; T:6166426; D:2891371 ]
executing statement <24763620>:
[reused=1;params={(String)Mike,(String)EN,(int)1}]
And the second INSERT fails on Oracle because FIRST_NAME is null, and
the table definition requires it to be NOT NULL.
Is there anyway I can get Kodo to figure out its dealing with the same
table for inserting the link columns and the full row, and optimize
accordingly i.e do one INSERT for LANGUAGE_PERSON?
I guess my only other options are a) introduce an explicit link table or
b) define a custom mapping?
Thanks,
Mike.There are examples of 1-Many mappings in the documentation:
http://www.solarmetric.com/Software/Documentation/latest/docs/
ref_guide_meta_examples.html
The important point I think you've missed is that right now, 1-many
mappings always require an inverse 1-1 mapping. Again, see the docs
above.
So your LanguagePerson needs a field of type Person, and whenever you add
a LanguagePerson to a Person, make sure to set that LanguagePerson's
Person too. LanguagePerson.person will use the same PID column as
LanguagePeson.pid. Kodo has no problem with having 2 mappings
mapped to the same column.
Kodo 3.0 will allow 1-Many relations without an inverse 1-1. -
I'm working on a report and one of the fields that I use to pass a parameter shows with no data but it has a length of 1. I can run a query that shows the data that I need if I enter in the criteria 'IS NOT NULL'. Is there a way to pass this value or set the parameter initial value to not null?
OK, if i understand correctly now, the root of the problem is that there is no Team information, but functional group information exists. If this is true, then my first thought is that the root problem lies in data entry, but that is another story.
I think what you want to do is force the team information to come across, even if it has been left out (if functional group information exists). To accomplish this, try adding an outer join to your WHERE clause this way:
WHERE
team(+) = :TEAM
Also, add a NVL around TEAM in the select statement like this:
closeddate,
NVL(team, 'Unknown Team'),
functionalgroup
Depending on the data relationships, you may have to play with the outer joins some to make sure you are returning the correct data set. In fact, now that I think about this, the table you are querying off of is a custom table/view isn't it? The problem then may truly lie in the script used to create the table. There are still some possibilities as to why you are experiencing this problem. If the table/view is a custom table/view, please post the script used to create it. If you have TOAD, open up a schema browser and select the table on the left. This will open up the table on the right hand side. There is a tab across the top labeled 'Scripts'. Copy and paste what is under this tab so I can advise further. If you don't have TOAD, you're going to need another way to find out what tables the data is being pulled from.
Again, my guess is that the field is NULL and Reports is just using a place holder to tell the developer that the field does indeed exist.
Anyway, I hope I've helped shed some light on the problem and that you get some ideas over the weekend!
Good luck,
Steve -
Hi, I am trying to properly display a list of tasks for a project however without a join to the project number (which I was aware of) and the employee table, I get over 500 results.
The task can be created without a employee assigned to it so therefore the page does not require the field to be filled in.
Here is the SQL code, any does anyone have any ideas?

BOOLEAN DEFAULT FALSE NOT NULL for key-column
Hello,
These statements show an unexpected behavior when a column is added to a table as 'BOOLEAN DEFAULT FALSE NOT NULL' and added afterward to the table's primary key column set:
create table test_1 (a char(1))
insert into test_1 values('A')
alter table test_1 add b boolean default false not null
alter table test_1 add primary key (a,b)
create table test_2 (a char(1), b boolean default false not null)
insert into test_2 (a) values('A')
alter table test_2 add foreign key f_test_1 (a,b) references test_1 (a,b)
-> [350]: Referential integrity violated
update test_1 set b=false
alter table test_2 add foreign key f_test_1 (a,b) references test_1 (a,b)
-> success
delete from test_2
delete from test_1
insert into test_1 (a,b) values('A',false)
insert into test_2 (a) values('A')
-> success
I think the error message '[350] Referential integrity violated' should not happen because the column 'b' really contains 'false'. But there obviously seem to be a difference before and after setting the column 'b' explicitly to 'false'. I can imagine that this depends on the way how the index for the primary key is updated. Probably the index is not properly updated in this context(?)
GabrielHi Gabriel,
you're right, this is a bug and indeed seems to caused by the way the DEFAULT boolean is stored in the page.
(There is no separate index for the primary key in MaxDB as all data is stored in B*trees - basically the table is the primary key).
This is how the record looks like when column b is 'false' only due to the change of the DEFAULT value:
ROOT/LEAF 460 perm entries : 1 [block 0]
bottom : 93 filevers: 14888 convvers: 83
writecnt: 1
1: (pos 00081)
00001 recLen : 12 recKeyLen : 4
00005 recVarcolOff: 0 recVarcolCnt: 0
record
1 2 3 4 5 6 7 8 9 10 11 12
81 82 83 84 85 86 87 88 89 90 91 92
dec: 12 0 4 0 0 0 0 0 32 65 0 0
hex: 0C 00 04 00 00 00 00 00 20 41 00 00
chr: A
And this is how it looks like after the explicit UPDATE:
ROOT/LEAF 460 perm entries : 1 [block 0]
bottom : 93 filevers: 14888 convvers: 84
writecnt: 2
1: (pos 00081)
00001 recLen : 11 recKeyLen : 3
00005 recVarcolOff: 0 recVarcolCnt: 0
record
1 2 3 4 5 6 7 8 9 10 11
81 82 83 84 85 86 87 88 89 90 91
dec: 11 0 3 0 0 0 0 0 32 65 0
hex: 0B 00 03 00 00 00 00 00 20 41 00
chr: A
Little difference but this leads to the problems during the foreign key validation.
I'll inform the developers next week about this.
As a workaround you'll have to explicitly update the columns for which you change the default setting.

ORA-01400 - not null column with default value and item with authorization
I've searched - I would think someone has run into this. APEX 3.0.0.00.20 - I've created a simple form on a table. One of the column is a not null column with a default value. I have a select list on that item, but it has security on it - authorization scheme. So, it checks the user and if that user isn't of the right role, it will not even display that item. However, APEX appears to still send in the column in its sql! So, the default value is useless, it sends in null each time. Even if I set the default at the Item level, I get null. Argg. That's got to be a bug...
In debug, I do not see the item listed at all. It's not used. That's fine - but why is it trying to insert the value? I would think it would leave it off??? I think because the item is associated with a database column. But, getting around this is ugly. Having to create a hidden item for each one, and then check to see if I need to take the list value... horrible. Any way to get around this???I should add - I guess I can always put my own custom process in to replace the DML. Just seems like a simple thing - if the value doesn't appear on the debug, isn't set with any default value... don't include it in the DML.

Get list of Not Null and PK Columns
hi All,
I need to get the list of all the columns which are part of PK and not null, can you help me on this?
with the below query I am getting the not null ones but need to get the PK columns also

NeilGive this a go. It includes by bitval solver function, as the status column is stored that way.

INSERT INTO @numbah (num) VALUES (@loopah)
SET @loopah = @loopah + 1
END
WHILE @val > 0
BEGIN
INSERT INTO @result
SELECT MAX(id), MAX(bitvalue) FROM @bitTranslate WHERE bitvalue <= @val
SELECT @val = @val - MAX(bitvalue) FROM @bitTranslate WHERE bitvalue <= @val

Can someone explain why 'Y' = 'N' is not working with PARALLEL Plan? i.e. With the filter like 'Y' = 'N' specified and if PQ is used , it does not return instantly. In fact it reads the entire table.
Here is the test case.. Goal is to execute only one of the SQL joined by union all. I have included 'Y' = 'N' in both SQLs for the test purpose.

I think you should pass this to Oracle Corp. as a bug - using the smaller data set.
The problem seems to be the way that Oracle combines multiple lines of a plan into groups of operations (as in PCWC, PCWC, PCWP). It looks like this particularly example has managed to fold the FILTER into a group in such a way that Oracle has lost track of the fact that it is a 'pre-emptng - i.e. always false' filter rather than an ordinary data filter; consequently the filter doesn't apply until after the hash join starts running.
In my example (which did a broadcast distribution) I could see that Oracle read the entire first table, then started to read the second table, but stopped after one row of the second table, because my plan allowed the join and filter to be applied immediately after the first row from the second table. And I think Oracle decided that the filter was alway going to be false at that moment - so stopped running the second tablescan. You've used a hash/hash distribriution, which has resulted in both scans completing because the slaves in each layer don't talk to each other.
