UNION operator in ejb 3.0

Hi All,
I have to use UNION operator in my ejb ql. My underlying database is MySQL.
My ejb ql is
SELECT s from eee s where s.name like 'XXX'
UNION
SELECT t from eee t where t.default_id = 'XXX'
union is on the same entitybean.
In my eee entity bean I have tried
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
Ejb ql doesnot return the expected results.
Could someone please help me out with UNION operator in ejb 3.0
Thanks

you should have little problems, but just how little is container specific. I successfully run JEE 1.4 stuff on JBoss 5.1 for example without having to make any configuration changes. Heck, I mix that technology with EJB 3 tech, even having shared container managed transactions.
BTW: you mean JEE5, not J2SE 1.5. Big difference in what they represent.

Writing query using UNION Operator

Question -
(1)
Write an SQL Statement to list the following items: Customer ID, Customer Name, number of invoices, sum of total for invoices. Ensure that all customers are returned in the result set.
Answer for the above is written as below by one person. That seams to be correct. Is there another way of writing this same query.;
select c.CUSTOMER_ID,c.NAME,i.cnt,i.s
from gee_customer c,(select customer_id,count(*) as cnt, sum(TOTAL) as s
from gee_invoice
group by customer_id) i
where c.CUSTOMER_ID = i.customer_id (+)
(2)
My other question is How to write the above answer (or what you sugest) using UNION operator ?
Any ideas please

In fact the outer join means you use the union of two result sets - usual join result
and the rows from the outer table for which there is not any row in the inner table.

Using union operator in discoverer

Hi All,
I have a sql statement which is to be implemented in discoverer:
(select ........where user_entered_date='YYYY/MM/DD' )
UNION
(select ........where user_entered_date='YYYY/MM/DD'
AND (select ........where user_entered_date='YYYY/MM/DD' ))
Problem:
a) There are nested select statements which require parameters to be entered by the user.
b) How would I implement the union operator in the above scenario?
I would really appreciate it if someone could give a work around.
Regards,
Nav

Hi,
Unfortunately, we can not have a SQL query with Union in Discoverer directly.
You should create a view based on the complete query and then create folder using the view.
You can provide a parameter at the report level.
For eg :
View query : select as_of_date from table_name
Report : Add a paremeter for as_of_date
Hope this Helps!

Creating table or View using UNION Operator ???????

Hi all
please need some help ,i have created aquery using UNION operator

it gives the output correctly and i need to make this output as View ot table

Create or replace view v_1 ...........
it gives me this error :: unknown command "UNION" - rest of line ignored.

Hi,
I found there is no error in your sql
create view x_v
as
select a from x
union
select to_number(null) from y;
this works fine.
in your sql check your right or left peranthesis

ROWNUM in UNION operator

All,
I have a requirement in SQL that I have to number each row. Hence I thought of using ROWNUM. But the sql query I'm using uses UNION operator. Hence I used like this
select a,b,rownum as 'field1' from table1
union
select c,d,1 as 'field1' from table2
Will the above query solve my purpose?
thanks

This will probably kill the purpose of UNION - which is to take only the DISTINCT rows..
If DISTINCT is not intended, it is better to choose UNION ALLYes, you are correct about use of UNION. Probably, OP would have wanted to use Union ALL perhaps, but might have forgotten about suppressing of duplicates and sorting and ended up using Union.
But, in accordance with the original query used by OP, my suggestion of row number would not affect the output, I guess, would it?
Perhaps, if OP would have provided us with some base sample data and the Output desired from it, it would have been of greater help.

Xpath union operator (|)

I am having trouble using the xpath union operator (|).
The selectNodes method of the oracle.xml.parser.v2.XMLNode is throwing an exception when I use any xPath expression with a pipe such as the one below. Does the Oracle Parser support this type of xPath operator?
Thanks,
Michael
//test/me[@id=3|@id=5]
<test>
<me id="5">you</me>
<me id="3">be</me>
</test>

I discovered that this XPath returns the expected result:
//test/me[@id=3]|//test/me[@id=5]

Union operator between tables

Hi everyone
I need to merge the data from two omogenous tables (be aware: two tables not two data services; the tables are populated by the user). I specifically need to do this client-side.
When I try to connect the out port of a table to the union operator, the input ports of the operator are grayed out.
I assume the union operator can be used only to merge data from data services: has anyone faced this issue before?
Thanks
Points will be awarded
VT

Hi Vincenzo,
this is where you reach some limitations in the Visual Composer.
The union operator is made to work on data services, not on tables.
The only ways to solve this are either to use another tool (WebDynpro) or to make use of a data service that would perform the necessary operation for you (creating a specific RFC or Web Service).

Performing database operations using EJB 3.0

I need to create a session bean that will perform operations on backend database. I am new to EJB 3.0 and need a gentle guidance to the solution
This is what I believe is suppose to be done
1. Create stateless bean interface marking operations.
2. Create bean implementation for above
3. Init stage will require me to connect to the Oracle database. Now am confused how will it get the connection details? Is there a way to extract the url username and password using resource bendle which can be accessed from within bean implementation?
4. Bean method will perform update, read oprations
5. Predestroy will close the connection
6. A client will simply call this ejb with some input parameter(s)
Please let me know if am doing anything wrong here

If you use EJB technology for which it is designed, the container (server) will manage the transaction (and also the connections to the database) for you, so no creation or cleanup of connections on your part. I advise you to read into JPA which is designed to be used in conjunction with EJB tech. The books Enterprise Javabeans 3.0 and Pro EJB 3: the Java Persistence API may help you a lot.

File IO operation in EJB (Session Bean)

Hi all,
Requirement : Read contents of a text file and upload the same to Oracle database (table).
I have created a Java class (application kind of) which opens, reads a file and transfers its data to a Oracle table.
Can I instantiate the same class within a Session Bean to perform the same operation or as per the EJB Restrictions this is not supposed to be done?
EJB Specifications 2.1 pdf guide
(refer 25.1.2 Programming restrictions
An enterprise bean must not use the java.io package to attempt to access files and directories in the file system. The file system APIs are not well-suited for business components to access data. Business components should use a resource manager API, such as JDBC, to store data.
Awaiting ur responses at the earliest.
Thanking in advance,
Seetesh

Hi Kenneth,
Thks for ur post.
I have coded the same using Weblogic App Server 7.0 ie a jsp invoking a java class (FileIO.class)(using jsp:useBean) and writing which does the IO operation and this works just fine.
Will this work by replacing the jsp with a Session Bean.
ie Session Bean's business method executing the method in the FileIO.class

How to add an EJB to the Business Operation's EJB list?

IN Operator in ejb ql

I'm trying to write a query that use the in operator:
@NamedQuery(name="findAnswersByLoginIdAndQuestionList", query="select object(o) from Answers o Where o.loginId = :loginId AND o.questionId IN :questionId")but I'm getting an error:
Exception Description: Syntax Recognition Problem parsing the EJBQL [select object(o) from Answers o Where o.loginId = :loginId AND o.questionId IN :questionId]. The parser returned the following [unexpected token: IN].
What am I doing wrong here?

I'm looking through some documentation at http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/EJBQL5.html#72299
It looks to me like the IN does not support variables, the list must contain string literals. Quote:
An IN expression determines whether or not a string belongs to a set of string literals. Here is the syntax of the IN expression:
in_expression ::=
single_valued_path_expression
[NOT] IN (string_literal [, string_literal]* )
I'm sure there's some trickery that can get it to do what you want, though.
Also, no matter what you try, I would definitely suggest that you put the ( ) around your IN list. I assume in your example, questionId was a comma separated list, and the questionId string contained the parentheses. I don't think that will work.
Also, I suggest looking at the IN that is part of the FROM clause, to see if it does what you wan.

Can anyone please explain the output of BLOCK 1 and 2? Why doesn't bulk collect into col1 and col2 return 11 as count?

Consider the following code from your block.
select *
bulk collect into col1
from (
         select *
           from table(cast(col1 as coltest))
          union
            all
         select *
           from table(cast(col2 as coltest))
       ); Now my assumption would be like this.
PL/SQL engine would recognize the SQL part and will be sending it to SQL Engine for processing. Before doing that it will try to initialize the SQL collection variable COL1. Now when SQL Engine process the SELECT, COL1 would be empty already. And thats the reason you don't get the as 5 and not 11.
