EJB QL Syntax

Hello
Can anyone help me with the EJB QL syntax for a find method (findByGroup(GroupLocal group)). I've got
"select distinct object(e) from Employee e,
in (e.group) as g where g=?1"
and when I verify I get the error
"Error: [ select distinct object(e) from Employee e,
in (e.group) as g where g=?1 ] has parsing error(s)
Exception occured : [Encountered "in ( e . group" at line 2, column 1.Was expecting one of: "AbstractSchemaName" ... "IN" "(" "IdentificationVar" "." "SingleValuedCmrField" ... "IN" "(" "IdentificationVar" "." "CollectionValuedCmrField" ...
EJB QL statement : 'select distinct object(e) from Employee e,
in (e.group) as g where g=?1'
EJB QL method : public abstract java.util.Collection employee.EmployeeLocalHome.findByGroup(group.GroupLocal) throws javax.ejb.FinderException]"
Thanks in advance

Hello
Can anyone help me with the EJB QL syntax for a find
method (findByGroup(GroupLocal group)). I've got
"select distinct object(e) from Employee e,
in (e.group) as g where g=?1"Hmm. Are you absolutely certain that GROUP indeed is defined as a CMR field for the abstract schema (table) Employee?
Do you have something like:
<cmr-field>
<cmr-field-name>group</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>In your ejb-jar.xml ?

Is it possible to use in EJB QL syntax "a.id IN (1,2,3,4)"

I want to execute query like
public Collection findbyIds(Integer[] ids);
SELECT ... FROM Orders o WHERE o.id IN (?1) so, it become
SELECT ... FROM Orders o WHERE o.id IN (1,2,3,4)
Is that possible?

I've used 'IN' operator in EJB Finder ejb-ql and it doesn't work. There isn't compile error when building EJB_project.jar, but 'IN' isn't relevant in ejb-ql. Try to change your SQL statement or use weblogic-ejb-ql.

Error while deploying EJB

Hey Folks
I am getting following error while deploying my ear file
Auto-deploying sample-ejb.jar (No previous deployment found)... Error compiling D:\J2EE\SAMPLE\bin\SAMPLE/SAMPLE-ejb.jar: Syntax error in source
can anybody plz tell me why it is coming

Hi manishnsachdev,
As per specs :
The ObjectNotFoundException exception is thrown by a finder method to indicate that the specified EJB object does not exist.
Since you're not executing any finder methods in your code, you should change your method signature to exclude the ObjectNotFoundException.

Problem while using aggregate functions in EJB QL 2.1

Hai all,
I am using aggregate function as follows
select max(c.id) from customer as c
for this iam selected check box EJB QL 2.1 in persistent.xml
this is validated by nwds, but while deploying server raising error like ejb ql syntax error.
Actually according to EJB QL 2.1 this is a valid query, what i need to do for run this same query .
Anybody please help me in this regard
Regards
Somaraju

Beevin
Both two are not even validated,
but with the first one as select max(c.id) from customer as c , in this case it is validated but while deploying it is error as , object must be return
But when i saw the ejb2.1 specification we can write this type of queries also ?
Is it problem with was any thing

EJB QL "LIKE" PROBLEM

Hai All.
I got an error when put this EJB-QL syntax :
<query>
<query-method>
<method-name>findByName</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<ejb-ql>SELECT DISTINCT object (a) FROM DummyData a WHERE a.name LIKE ?1</ejb-ql>
</query>
Seems like this method cannot take an arguments, because it runs well when I change the <ejb-ql> syntax with harcode query like this :
<ejb-ql>SELECT DISTINCT object (a) FROM DummyData a WHERE a.name LIKE %FOO%</ejb-ql>
Is there something wrong with my first syntax?
or the EJB-QL cannot take an arguments for LIKE operator in EJB 2.0??
Below is the error output
Auto-deploying file:/C:/NS/jdev/TAX_WORKSPACE/TAX_PROJECT/classes/ (No previous deployment found)... Encountered "a . birthdate LIKE ?1" at line 1, column 7.

Thanx in advance

Hi,
You can achieve this by overriding EJB-QL in orion-ejb-jar.xml file. Please look at
http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/a97677/ql.htm#1005714
So you can have something like
<finder-method query="$name like $1"> in orion-ejb-jar.xml
and a dummy (but valid) ejb-ql in ejb-jar.xml, like
<ejb-ql>SELECT DISTINCT object (a) FROM DummyData a WHERE a.name =?1</ejb-ql>
Hope this helps,

Converting Native SQL to EJB ql

Hi there
Simple enough question, how would I go about converting the following native SQL query into EJB QL syntax. This by the way is a simple search on keywords attributed to a person.
SELECT PersonId, COUNT(word)
FROM keyword_table
WHERE word = 'a' OR word = 'c' OR word = 'b'
GROUP BY PersonId HAVING COUNT(word) <= 3
ORDER BY COUNT(word) desc
Note that PersonId is a foreign key joinColumn to a Person entity bean, Ideally i want to be returning person objects through a foreign key in my interest table using GROUP BY etc. I had something like this in mind:
select Person p FROM Interest i WHERE i.Word = 'a' OR i.Word = 'c' OR i.Word = 'b'
GROUP BY i.Person.PersonId HAVING COUNT(i.Word) <= 3
ORDER BY COUNT(i.Word) desc
Kind Regards

suppose there are two beans "Account" and "Transrecord" with 1-to-m relationship, the mapping table is "ACCOUNT"(PK is ACCID) and "TRANSRECORD"(FK is ACCID)
The cmr field in Account is "transrecords" and the cmr field in Transrecord is "theAccount".
For a SQL statement (this statment may be not that meaningful, but it is for testing the function of my translation tool):
SELECT t.* FROM TRANSRECORD t , ACCOUNT A WHERE a.ACCID = t.ACCID
>>
one other way of translation would be
Select object(t) from account a,transrecord t where a.accid = a.transrecords.accid
select q1.*
from TRANSRECORD q1, ACCOUNT q2
where ( q2.\"ACCID\" IS NOT NULL ) and ( q2.\"ACCID\" = q1.\"ACCID\")");
Since ACCID is the primary key of ACCOUNT table, so "q2.ACCID IS NOT NULL " is always true, the >>SQL statement is equivalent
with the oringinal SQL statement.isn't it what is supposed to happen since you cannot have a record in the foreign key table without a corresponding record in the primary key table?
I tested it in Transrecord bean as a defined EJB-QL in WSAD, the generated SQL statement after the >>deployment is:I am using WSAD 5.1, which file has the converted SQLs?

Simple EJBQL query

I am trying to execute the following query.
SELECT OBJECT(e) FROM Employee e WHERE e.lastName = ?1 AND e.firstName = ?2 AND e.birthDate = ?3
But It is always returning FiderException, although the record I want to search exists in DataBase. ?
What could be the problem

Then it may be problem will your data. char and varchar are stored in different way. Also remove the leading and trailing spaces. I am assuming that ejb ql syntax is correct since your container tool will give you error if not correct.

Paging in ejbql 2.x

Hi developers,
I am developing on old entity EJB 2.x and need to achieve paging.
As we all know, offset and limit operators are unavailable in EJB-ql syntax lower than 3.0
How can I work around that?
Should I go down to the dreaded JDBC?
Thanks in advance

Pls help - Syntax question about EJB QL

Hello,
I'm new learner on EJB. I went through the specification 2.0 of EJB QL released by Sun, I'm not quite understand the syntax definition of SELECT clause in finder method which described in the following words:
"In the case of a find method, the SELECT clause is restricted to contain either a single range variable or a single value path expression that evaluates to the abstract schema type of the entity bean for which the finder method is defined.
Because finder method cannot return arbitrary types, the SELECT clause of an EJB QL defined for a finder method must always correspond to the abstract shcema type fo the entity bean for which the finder method is defined.In contrast, the SELECT clause of a query defined for a select method can return the abstract schema types of other entity beans or the values of cmp-fields."
As my understanding, I think the SELECT clause of finder method can only contain a single range variable instead of single value path expresson, it should have only one format, which is "SELECT [DISTINCT] OBJECT(identification_variable)".
For example: the query below is defined in OrderBean findByProductType();
SELECT OBJECT(o) FROM Order o, IN(o.lineItems) l
WHERE l.product.product_type = 'schoolsupplies'
how it could be a single value path expression , I think this format can only be used in Select method.
The other thing is EJB QL2.0 does not support subquery and "NOT EXIST" clause, does this mean that a SQL query with subquery or "NOT EXIST" clause can't be translated to EJB QL?
I don't know if I'm correct or not. I'd appreciate if anybody can help me with this.
Thanks!

Hi,
Weblogic
=======
In the Weblogic-cmp-rdbms-jar.xml file, we define the Table name as created in the DBMS along with cmp-field mapped to the dbms-columns of the table as described below
<table-map>
<table-name>SalesAccounts</table-name>
<field-map>
<cmp-field>salesaccountId</cmp-field>
<dbms-column>sales_acctid</dbms-column>
</field-map>
<field-map>
<cmp-field>salesbalance</cmp-field>
<dbms-column>sales_bal</dbms-column>
</field-map>
<field-map>
<cmp-field>salesaccountType</cmp-field>
<dbms-column>sales_type</dbms-column>
</field-map>
</table-map>
Here SalesAccounts is the actual table defined in DBMSD like Oracle say which has columns sales_acctid, sales_bal and sales_type.
In ejb-jar.xml, you define an abstract schema name ie some sort of alias for your table name (SalesAccounts) along with defining the cmp fields required for writing a EJB-QL.
<abstract-schema-name>SalesAccountBean</abstract-schema-name>
<cmp-field><field-name>salesaccountId</field-name>
</cmp-field>
<cmp-field><field-name>salesbalance</field-name>
</cmp-field>
<cmp-field><field-name>salesaccountType</field-name>
</cmp-field>
<primkey-field>salesaccountId</primkey-field>
Here salesaccountid is defined as a Primary key.
Now your EJB-QL can be defined in the ejb-jar.xml file as follows
<query>
<query-method>
<method-name>findSalesAccountsCondition</method-name>
<method-params>
<method-param>double</method-param>
</method-params>
</query-method>
<ejb-ql>
<![CDATA[SELECT OBJECT(a) FROM SalesAccountBean AS a WHERE a.salesbalance > ?1]]>
</ejb-ql>
</query>
This should clear ur doubts. Case u have any, revert back to me.
Rgds,
Seetesh

Dynamic query syntax for EJB

If i'm going to let the user search the database table (eg. Employee) based on 4 parameters, ie. employee id, employee name, position and address. In cmp entity bean, the stupid way is to create (2 power of 4) findByMethod ejb-ql statements to fulfill the search. Is there any dynamic way to do the querying of table for cmp bean with only one findByMethod?
Any suggestions or help would be much appreciated. Thanks.

Hi Julius,
CMP unfortunately does not support dynamic OQL methods (unless something has changed since the last time I looked at the specs). There are however tools and software (eg powertier) that can provide this type of functionality (like a generic findBySQL(String sql) method) on some J2EE servers.
One way to solve it of course is to have 4 different methods, and then in your java code have a case or if statements selecting the correct one based on what the user enters. It is not a pretty solution but it would work.
regards,
Dion

Means theres an error in XML/ABAP conversion probably due a syntax error...

Can not use SUM in a simple query because of a syntax error?

Hi
Thank you for reading my post.
I am trying to execute the following query:
q = em.createQuery("SELECT SUM((NE.pipeLength - 0.6)+((NE.networkDepth-NE.initialDepth)*0.41)+ NE.standLenght) FROM NExpansion NE where (( NE.contract.contractor=:contractor) AND (NE.pDiameter=:diameter))");
              q.setParameter("contractor", contractor);
q.setParameter("diameter", diameter);
     l = (Long) q.getSingleResult();And I get the following error:
Caused by: Exception [TOPLINK-8025] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.EJBQLException

Thanks.

Hello,
From the grammar in the JPA spec, SUM only takes a state_field_path_expression which is defined as
state_field_path_expression := {identification_variable | single_valued_association_path_expression}.state_field
Please feel free to file an enhancement to have this expanded upon.
Best Regards,
Chris
