EJB finder query with ORDER BY clause

Hi,
How to query the data in ordered list using Order By clause in the entity Bean.
Here is the part of My code in which i am interrested.
/* @ejbgen:finder
* signature = "Collection findAllData()"
* ejb-ql = "SELECT OBJECT(z) FROM DataProfileBean AS z"
abstract public class DataProfileBean extends EntityAdapter {
* @ejbgen:cmp-field column = DATA_PREFIX
* @ejbgen:primkey-field
* @ejbgen:local-method transaction-attribute = Required
public abstract Integer getDataPrefix();
public abstract void setDataPrefix(Integer DataPrefix);
Now what modification needs to be done in the ejb-ql query to find the DataPrefix in the sorted list.
Regards,
Dilip

I don't think the current spec for EJBs support ORDER BY. But Weblogic has an extension that you can use (that is, if you're using it). Here's the info: http://e-docs.bea.com/wls/docs61/ejb/cmp.html#1076421

Query with order by clause

Hi,
I found a query with order by clause in procedure which is taking long time.
Stats are upto date.
Total Rows :650000.
It is ordered by primary key column.
select * from table_name order by col1;
col1 is a primary key.No of cpu's used is 4.
can anyone suggest me a better solution to improve the performance of a query.
Is it better to use parallel hint for above scenario.
Any help really apprecaited.
Thanks in advance.

Hi,
Thanks for ur immediate reply.
It doesn't have where clause.
below is the plan

Oracle query tuning : query with Order-by clause

Hi
I am having a query in my database :
SELECT * FROM SAPR3.HRP1001 WHERE "MANDT" = 990
ORDER BY
"MANDT" , "OTYPE" , "OBJID" , "PLVAR" , "RSIGN" , "RELAT" , "ISTAT" , "PRIOX" , "BEGDA" , "ENDDA" ,"VARYF" , "SEQNR" ;

Since it is a issue with order by , it seems a PGA memory issue. there is 12GB PGA available but only 3GB gets allocated. pga_aggregate target is set in the DB. There is a index created for al the columns on order by, but it is not getting used.
pleas suggest me as I am running into major problems, i can post the output of any query u require from my side. Any help wil be highly apprciated.

Hi Rishi,
the provided execution statistics prove the opposite:
>Statistics
>...
>0 sorts (memory)
> 1 sorts (disk)
>512992 rows processed
This indeed was a single-pass sort, which means it had to use the temp tablespace for one pass of the sorting/grouping.
Remember that Oracle distinguishes three kinds of sorts: 1. "in memory", 2. "single-pass" and 3. "multi-pass".
Only the first one won't need to spill out data to the disks. The others do this by definition.
BTW: the file read times in ST04 are aquired through Oracle V$ views and not directly from the OS - that can make a big difference sometimes.

Default where with order by clause

Hi all
How to use Default where with order by clause
for example i want to use Default_where clause with order by clause
Regards
Shahzaib ismail

Hi,
I have a similar query for where clause.
my query-find form is a multi record form like below:
Criteria - Condition - Value
Item/Category/Planner (List_Item) - Equals/Among (List_Item) - text_FIELD
Item - Equals - ITEM_1
Category - Among - ('CAT1', 'CAT2')
Planner - Equals - PL1
Find_BUTTON Clear_BUTTON
User can select any criteria and condition combination and then enter the value in "Value" text field.
My query is: how can I prepare a where clause based on user input since the user can enter any number of values/combinations? I guess I would have to use some looping to generate where clause.
Thanks
Imran

21
22 ........
Please help me why it is not displaying like it. and how to make the statement to display like the second case. Thanks in advance.
Regards,
Uraja

The column datatype that you are selecting is not of NUMBER datatype(might be char or varchar2) hence you are getting such result set.
And for this purpose, it is recommended to set datatype of a column appropriately.
For now you can add TO_NUMBER function to column in ORDER BY clause, only if it has data of number type.

Improve performance of query with order by

Hello,
I have a query with a necessary "order by" which lasts 24 seconds. The same query without the "order by" lasts 1 second.
How can I improve the performance of the query with "order by"?
Thank you very much.
The query is:
select distinct CC.acceso,CC.ext_acceso,TIT.TITULO_SALIDA
from (((Ocurrencias CT01 inner join
     palabras p0 on (CT01.cod_palabra = p0.cod_palabra and p0.palabra like 'VENEZUELA%' AND p0.campo = 'AUTOR')) INNER JOIN
     CENTRAL CC ON (CT01.ACCESO = CC.ACCESO AND CT01.EXT_ACCESO = CC.EXT_ACCESO))) inner join
     codtit ctt on (CC.acceso = ctt.acceso and CC.ext_acceso = ctt.ext_acceso) inner join
     titulos tit on (ctt.cod_titulo = tit.cod_titulo and ctt.portada = '1')
where CC.nivel_reg <> 's'
ORDER BY 3 ASC;

My guess is SQL Scratchpad is a GUI and is not returning all the rows but just the first screenful. Without any order by or distinct the database can start returning rows as soon as it finds the first one. With an order or distinct it needs to sort the rows so the first row can only be returned after the last row is retrieved.
Open a command line prompt and run
sqlplus

ROWNUM can use with ORDER BY clause?

Hi
Following i have two quires in ROWNUM order for example..
1:query
select rownum,empno,ename,deptno from emp
where rownum <= 14;
result:
rownum empno ename deptno
1 7369 SMITH 20
2 7499 ALLEN 30
3 7521 WARD 30
4 7566 JONES 20
5 7654 MARTIN 30
6 7698 BLAKE 30
7 7782 CLARK 10
8 7788 SCOTT 20
9 7839 KING 10
10 7844 TURNER 30
11 7876 ADAMS 20
12 7900 JAMES 30
13 7902 FORD 20
14 7934 MILLER 10
2:Query , add ORDER BY clause it will change the sequence of ROWNUM.
select rownum,empno,ename,deptno from emp
where rownum <= 14
order by deptno;
result:
rownum empno ename deptno
7 7782 CLARK 10
9 7839 KING 10
14 7934 MILLER 10
1 7369 SMITH 20
11 7876 ADAMS 20
13 7902 FORD 20
8 7788 SCOTT 20
and so on......
but i want these records from 2 to 5...how i can query this through ROWNUM or any sequence because ORDER BY clause change the order of ROWNUM and i could get this result.

please send me general query which i can apply on any table.
advance thanks.

My guess is that you are looking for a pagination solution. If so, here is a thread on Asktom:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:127412348064
So, essentially, you ORDER BY first and then write a wrapper to get your the rownum.
If you do it this way, You will also use the top-n optimization that Oracle uses.

Sub query with order by

Hi ,
I have created a sub query with order by on a column.( i have cutomized the IKM control append to put order by).I can see the order by condition.If i use this subquery(yellow interface) in main query(is also yellow interface) i can't see the order by condition
Subquery(Q-yellow interface):
select
PID,
     START_TIME,
     ACTION_TYPE_CODE
FROM
select      DISTINCT
     SERVICE_TRACKING_S.PID PID,
     TO_TIMESTAMP(TO_CHAR(SERVICE_TRACKING_S.ACTION_TIME,'DD-MON-YY HH24:MI:SS'),'DD-MON-YY HH24:MI:SS') START_TIME,
     SERVICE_TRACKING_S.ACTION_TYPE_CODE ACTION_TYPE_CODE
from     KSTGDB.SERVICE_TRACKING_S SERVICE_TRACKING_S
where          (1=1)
ORDER BY-----------------------------------------------
PID
,START_TIME ASC
ODI_GET_FROM
Main query(Q1--yellow interface):
select
PID,
     START_TIME,
     ACTION_TYPE_CODE,
     RN,
     RN_MAX
FROM (
select
     Q.PID PID,
     Q.START_TIME START_TIME,
     CASE WHEN Q.START_TIME-LAG(Q.START_TIME,1,Q.START_TIME) OVER (PARTITION BY Q. PID ORDER BY Q.START_TIME)> numtodsinterval(75,'minute')
or Q.PID!=LAG(Q.PID,1,0) OVER (PARTITION BY Q.PID ORDER BY Q.START_TIME) THEN 1 ELSE Q.ACTION_TYPE_CODE END ACTION_TYPE_CODE,
     ROW_NUMBER() OVER(PARTITION BY Q.PID ORDER BY Q.START_TIME) RN,
     count(*) over (PARTITION BY Q.PID ORDER BY Q.START_TIME ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING )
RN_MAX
from     (
select      DISTINCT
     SERVICE_TRACKING_S.PID PID,     TO_TIMESTAMP(TO_CHAR(SERVICE_TRACKING_S.ACTION_TIME,'DD-MON-YY HH24:MI:SS'),'DD-MON-YY HH24:MI:SS') START_TIME,     SERVICE_TRACKING_S.ACTION_TYPE_CODE ACTION_TYPE_CODE
from     KSTGDB.SERVICE_TRACKING_S SERVICE_TRACKING_S
where     (1=1)
----------------- i don't see order by here--------------------------------
) Q
where          (1=1)
) ODI_GET_FROM
thanks in advance

Hi,
Add a new KM step with the SQL you want to use for the sub query and select the +"Use Current Command for Derived-Table sub-select statement"+ checkbox. This new step can be the last one of your IKM.
Basically, you can copy the select statement of the "Insert new rows" step.

@afalty, the story you are telling about the order of the tables being important, from smallest to largest, et cetera, is only partially true and only when dealing with the rule based optimizer. Nowadays, almost everybody is using the cost based optimizer, so these remarks can very likely be ignored.
@original poster:
I think you are "measuring" the elapsed time by using TOAD, am I right? And you are probably writing 9 seconds, because it took TOAD 9 seconds before it could display the first records. If you would scroll down to the last record, it is likely taking much more time. A sort operation costs resources and time, but very unlikely this much.
When you want your rows sorted, all rows must have been visited before you know for sure which one is the smallest. That's why it takes longer to display the first row. Without an order by, the query can begin popping out rows much faster.

Rob.

IN clause with ORDER BY clause in sub-queries

Hello,
We generate dynamic queries with the following statement pattern (could be many union/intersect sub-queries):
select my_col
from my_table
where my_col IN
select table_2.my_col , x_col from table_2 where x_col > 10
UNION
select table_3.my_col , y_col from table_3 where y_col > 20
INTERSECT
select table_4.my_col , z_col from table_4 where z_col is between 30 and 50
I know that I can do just the sub-queries w/ an ORDER BY clause as follows (as long as the 2nd parameter in the select stmts are of the same type):
select table_2.my_col , x_col from table_2 where x_col > 10
UNION
select table_3.my_col , y_col from table_3 where y_col > 20
INTERSECT
select table_4.my_col , z_col from table_4 where z_col is between 30 and 50
order by 2 desc
But my questions are:
1. What is (if there is) the syntax that will ensure that the result set order will be that of the ordering of the sub-queries?
Or does my SQL stmt have to have syntactically (but not semantically) change to achieve this?
Thanks,
Jim

just a minor doubt - I think it is not officially supported to have separate ORDER BYs in a compound query with set operators (e.g. UNION / UNION ALL subsets). Of course one could use inline views with NO_MERGE + NO_ELIMINATE_OBY hints, but I think the only officially supported approach is to use a single, final ORDER BY (that needs to use positional notation as far as I remember).
Randolf,
You're right, of course, about the separate "order by" clauses.
Interestingly the following type of thing does work though (in 10.2.0.3, at least):
with v1 as (
    select * from t1 where col1 = 'ABC' order by col2
v2 as (
    select * from t1 where col1 = 'DEF' order by col2
select * from v1
union all
select * from v2
;A quick check the execution plan suggsts that Oracle appears to be convering this to the following - even though its technically not acceptable in normal circumstances:
select * from t1 where col1 = 'ABC' order by col2
union all
select * from t1 where col1 = 'DEF' order by col2

Not able to migrate a query with not exist clause

Hi all,
I'm using Toplink 10.1.3 and I am trying to rewrite the following query with Expression Framework:
select distinct r.e_ogg_oper_k_oggetto
FROM regola_accettazione_oper_banc r, oggetto_operazione_bancaria o
where not exists (
select 1
FROM limitaz_ogg_tipo_oper_banc l
where nvl(l.d_fine_validita,trunc(sysdate)+1)>trunc(sysdate)
and l.d_inizio_validita <= trunc(sysdate)
and l.e_tpodv_k_tipo_operazione=:appoggio.tipo_operaz
and l.e_ogg_oper_k_oggetto=r.e_ogg_oper_k_oggetto
and l.e_uni_oper_k_unita_oper_util= :appoggio.e_uni_oper_k_unita_oper_esegui )
and r.e_oper_ban_k_operaz_bancaria=:appoggio.form
and r.e_ogg_oper_k_oggetto=o.k_oggetto
and o.e_ogg_oper_k_oggetto is null
and o.k_oggetto != nvl(:appoggio.oggetto_autom,,'0')
and o.k_oggetto like substr(:appoggio.oggetto,1,2)||'%'
and r.d_inizio_validita <= :appoggio.d_contab
and to_date(nvl(to_char(r.d_fine_validita,DD/MM/YYYY'),31/12/3999'),'DD/MM/YYYY')> :appoggio.d_contab
and o.f_natura_oggetto in ('G','P') and r.f_oggetto_automatizzato!='S'
I'm not able to "attach" the not exist clause to the rest of query.
How can I do it?
Thank you very much.

Not exists can be used in an expression through using a ReportQuery sub-query.
i.e.
ExpressionBuilder outerBuilder = new ExpressionBuilder();
ReadAllQuery outerQuery = new ReadAllQuery(Employee.class, outerBuilder);
ExpressionBuilder subBuilder = new ExpressionBuilder();
ReportQuery subQuery = new ReportQuery(Address.class, subBuilder);
subQuery.addAttribute("id");
subQuery.setSelectionCriteria(
subBuilder.get("city").equal(outerBuilder.get("address").get("city")
.and(subBuilder.notEqual(outerBuilder.get("address")))));
outerQuery.setSelectionCriteria(
outerBuilder.notExists(subQuery));
List results = (List) session.executeQuery(outerQuery);
Refer to the documentation section on sub-queries for more information.
I would suggest simlpifying the where clause until you get the sub-query working to start.
You can also always use a custom SQL query in TopLink.

Select statement takes very long to run with order by clause.

Hi all,
I have a select statement which when I run without the order by clause takes arround 2 minutes to run. But with the order by clause it goes on for ever. I am trying to access the database server through a network which is not too fast.
The select statement is based on 9 views which are again based on some views. It also has inline views and outer joins. These views and inline views can not be done away with.
When selected without the order by clause it gives 3215 records.
Anything like 2 to 3 minutes will be Ok.
Thanks.

Popup lov with order by clause

I created a form manually using the document from the url:
http://otn.oracle.com/products/database/htmldb/howtos/tabular_form.html#MANUAL
I used the following query from that document.
select htmldb_item.hidden(1,empno) empno,
ename,
htmldb_item.select_list_from_query(3,job,'select distinct job, job from emp') job,
htmldb_item.popupkey_from_query(4,mgr,'select ename, empno from emp',10) mgr,
wwv_flow_item.date_popup(6,null,hiredate) hiredate,
htmldb_item.text(7,sal,10) sal,
htmldb_item.text(8,comm,10) comm,
htmldb_item.select_list_from_query(9,deptno,'select dname, deptno from dept') deptno
from emp
This works fine.
But if I add an order by clause to the query the popup key for mgr column doesn't work.
select htmldb_item.hidden(1,empno) empno,
ename,
htmldb_item.select_list_from_query(3,job,'select distinct job, job from emp') job,
htmldb_item.popupkey_from_query(4,mgr,'select ename, empno from emp',10) mgr,
wwv_flow_item.date_popup(6,null,hiredate) hiredate,
htmldb_item.text(7,sal,10) sal,
htmldb_item.text(8,comm,10) comm,
htmldb_item.select_list_from_query(9,deptno,'select dname, deptno from dept') deptno
from emp
order by ename
Thanks
Chandra.
