Problems using native query in Active Directory connector v 9.1
Hello,
Has anyone ran into a problem when trying to do a query with a not operator?
I want to import all users, but not computers.. so I tried the query (&(objectClass=user)(!objectclass=computer))
I tried this query directly in the active directory and it worked.
The problem is when I apply it to OIM it gives out the following error:

Using Native Query to run a SQL statement, the "getResultList" throws excep

Hello,
I am using native query to search for results on my search page. A friend of mine just told me that I better use named query or the time to get my search results will be too slow.
Does Named Query give you faster result than Native Query?
Thanks in advance.
Regards,
HemenWhen you define named queries (note that this is a Hibernate example) you can put them in for example XML,
<query name="findItemsByDescription">
<![CDATA[from Item item where item.description like :desc]]>
</query>or a SQL query like
<sql-query name="findItemsByDescription">
<return alias="item" class="Item"/>
<![CDATA[select {item.*} from item where description like :desc]]>
</sql-query>You can call these queries by using the same code, for example,
session.getNamedQuery("findItemsByDescription").setString("desc", description);This is what is being meant by sharing the same calling API.
When taking about performance. You have to know something about what goes on under the hood.
You have probably programmed something using straightforward JDBC, so you know how to queries
get passed to the driver and send to the database. When using HQL or JPA-QL the queries first have
to be parsed into an SQL language that the database can understand. In this case, we have an extra
parsing step in between. Note that Native SQL queries, including stored procedure calls, the persistence
framework still takes care of mapping the JDBC result sets to graphs of persistent objects.
If you want to include a native SQL hint to instruct the database management systems query optimizer,
for example, you need to write the SQL yourself. HQL and JPA-QL do not have keywords for this.
The disadvantage of putting native SQL in your mapping metadata is lost database portability, because
your mappings, and hence your application, will work only for a particular database. But usually this is of a
minor concern as you are probably not creating a framework that has to work on every database.
When you want to get behind the performance of your query, you really have to consult the database
and look at the execution plan - A DBA can tell you exactly what is good and what can be optimized. -
Issue in running GTC having Customized & native query
Hi Experts,
We are creating "OIM 9.1 - OIM11g SYNC GTC". When Scheduled task is run, this GTC should be updating the records of OIM11g by taking the data from OIM 9.1 DB.
We have used the following connection parameters:

How to define a JPA "Entity" used to query multiple database tables
While using JPA to access database, I have a need to define a generic "Entity" class to use for query different tables. The reason is I have a lot of non-business tables (reference tables) I need to query. I intend to use Native SQL to do the query. Most query will only return 1 - 3 columns. It is tedious to define many JPA entities only to use them sparsely.
For example, if I have two Native query, and define a JavaBean that has 3 properties, how do I implement this in JPA?
Thanks for your help.
query 1:
select LASTNAME as f1, AGE as f2 from PERSON
query 2:
select zipcode as f1 from LOCATION
package model.uti;
public class SimpleBean {
private String f1;
private String f2;
private String f3;
public SimpleBean() {
public void setF1(String f1) {
this.f1 = f1;
public String getF1() {
return f1;
public void setF2(String f2) {
this.f2 = f2;
public String getF2() {
return f2;
public void setF3(String f3) {
this.f3 = f3;
public String getF3() {
return f3;
}An @Entity is mapped to a specific table. You can't fill it with totally random data from a collection of tables.
If you want to access data from multiple tables within the one entity, then the JPA spec defines an annotation @SecondaryTable, which allows you to specify a
second table and the join condition.
http://java.sun.com/javaee/5/docs/api/javax/persistence/SecondaryTable.html
The JPA spec talks about this as do most good EJB/JPA books.

Jpa native query returns only first character of a field
Hi,
I've a JPA native query that returns two fields from my oracle database. The first field is a CHAR(2) field with two char values in it, like 'OZ' etc.
The problem is, as soon as the query is executed it returns only first character of field1. If the actual value of field1 is like 'OZ' then it returns only 'Z'.
Query nativeQueryForProfileInfo = getManager().createNativeQuery(queryToRun);
List list = nativeQueryForProfileInfo.getResultList();
Please help,
thanksThere could be several explanations here and it's difficult to say without having more details, possibilities are
There is something wrong with your display logic.
There is something wrong with your mapping. -
Incremental variable in column native query
i'm looking for a jpql way of doing a cumulative variable query like subttl:
select scat.*, @subttl:=if(@subttl=null,0,@subttl) +imp*dh as subttl from scat;is there any way to use variables in the select clause ?...
As other way, I thought making a native query but I need the resultset mapped to an entity bean, so I think it can't be possible.
I appreciate your help!!Hi sebatxtz!
You can always use SqlResultSetMappings to map the result of a native query to entities.

As for your original problem, sorry I'm not that big of a jpql expert. :(

How to use Native SQL statement in JDBC receiver interface
Dear All,
Can any one please help us in using Native SQL statement in a JDBC receiver channel. The reason why I need to use Native SQL statement instead of standard XML structure is that I need to execute a dynamic SQL query in third party database system lke:-
Select Field1 Field2 from TABLE Where Field3 like "%Name'
I expect the the response in the form of XML file which I can pick up using synchornous interface as mentioned on help.sap.com:-
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
The value for %Name can change dynamically according to the transaction and hence cannot be inluded as a KEY element in standard XLM structure,
Hence I need to know:-
1. What message mapping I should use in case if I have to use Native SQL statement.
2.What operation mapping I should use in case if I have to use Native SQL statement.
If guess correclty I may have to use Java mapping to do the above activities. Hence I want to know
3 .How do to go about it to do the Java mapping.
Thanks

You can use a stored procedure, and call it from jdbc receiver adapter.
I also solve this issue, with a DBLookup in message mapping. You can refer to my blog, and this usefull 3d:

Workaround for opening a strongly typed cursor using native dynamic SQL
Hi All,
In reading the PL/SQL documentation for Oracle 9i, I noted that the OPEN-FOR
statement with a dynamic SQL string only allows the use of weakly typed cursors.
I have verified this limitation with my own experimentation as follows:
DECLARE
type rec_type is record(
str varchar2(40),
num number(22)
type cur_type is ref cursor return rec_type;
my_cur cur_type;
que varchar2(100);
tab varchar2(40);
BEGIN
tab := 'dynamic_table_name';
que := 'select key_name, key_value from ' || tab || ' where key_name like ''01%''';
open my_cur for que;
loop
if my_cur%found then
dbms_output.put_line('source_name: ' || my_cur.str || ', page_sn: ' || my_cur.num);
exit;
end if;
end loop;
close my_cur;
END;
Running the above trivial example in an anonymous sql block yields the following
errors as expected:
ORA-06550: line 10, column 8:
PLS-00455: cursor 'MY_CUR' cannot be used in dynamic SQL OPEN statement

ORA-06550: line 13, column 7:
PL/SQL: Statement ignored
Is there a workaround to the situation? Since I do not know the table name at run
time, I must use Native Dynamic SQL. I have a long and complex record type
that I wish to return through JDBC using the REFCURSOR Oracle type in order to
avoid having to register an inordinate number of OUT parameters. Moreover, I
would like to return potentially one or more results in a ResultSet. Using the
standard method of registering native SQL types for the IN and OUT bindings
can only return one result. Hence the reason I would like to return a strong
cursor type. Also, the type of query I am doing is complex, and needs to be
executed in a PL/SQL procedure for performance reasons. Therefore simply
executing a SELECT query dynamically built up on the the JDBC client won't
do the trick.
If anybody has experience with a similar problem and would like to volunteer
information on their workaround, I would really appreciate it.
Best Regards,
J. MetcalfWe can use strongly-typed REF CURSORs in DNS, but the typing derives from a table e.g.
TYPE EmpCurTyp IS REF CURSOR RETURN emp%ROWTYPE;
so the problem is your use of "return rec_type" bit.
Forgive my bluntness but I think you have misunderstood strong and weak typing. You actually want to be using weakly-typed cursors. I mean this:
Moreover, I would like to return potentially one or more results in a ResultSet. suggests that the structure of your resultset may vary, which is precisely what a weakly-typed ref cursor allows us to do. Then we can use the JDBC metadata methods to interrogate the structure of the resultset, innit.
so try this:
DECLARE
type cur_type is ref cursor;
my_cur cur_type;
que varchar2(100);
tab varchar2(40);
BEGIN
tab := 'dynamic_table_name';
que := 'select key_name, key_value from ' || tab || ' where key_name like ''01%''';
open my_cur for que;
loop
if my_cur%found then
dbms_output.put_line('source_name: ' || my_cur.str || ', page_sn: ' || my_cur.num);
exit;
end if;
end loop;
close my_cur;
END;

Aggregate function in native query (EJB 3.0)
How do you run a aggregate function in a native query? I have a particular use case, for reporting purposes, where the result set is too large to fetch the actual CMP collection, thus I need to execute a native count/avg select. I want some thing like,
Integer totalRecords = (Integer)
em.createNativeQuery("select count(*) from records").getSingleResult();Oracle is intelligent enough to use index only if query result filtering is based on it and result set is less than 5% of the total data set.Sorry to be blunt but that 5% stuff is nonsense.
Here since the index column is not used in the WHERE clause, oracle performs full table scan.That's not true either. Under the right circumstances the optimizer can use the index, even without a WHERE clause in the query:
SQL> create table t as select * from dba_objects where object_type is not null;
Table created.
SQL> alter table t modify object_type not null;
Table altered.
SQL> create index t_idx on t(object_type);
Index created.
SQL> explain plan for
2 select object_type, count(*) from t group by object_type;
Explained.
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 44 | 396 | 60 (7)| 00:00:01 |
| 1 | HASH GROUP BY | | 44 | 396 | 60 (7)| 00:00:01 |
| 2 | INDEX FAST FULL SCAN| T_IDX | 72474 | 636K| 57 (2)| 00:00:01 |
-------------------------------------------------------------------------------With the OP's query, it (apparently) can not be satisfied by using only the index.
WHERE TO_CHAR(COL) = TO_CHAR(COL)I don't even know what this means. Usually if you perform a function on an indexed column, the optimizer will not use the index (unless of course it's an fbi). -
How can I add parameters to a native query?
The following approach does not work.
String query = "select * from a where type=:type";
Query q = em.createNativeQuery(query, A.class);
q.setParameter("type", 7);
q.getResultList();
I get the following exception:
