Simple table - complex query

Hi, I have a table with data very similar to the following....
NAME DATE
ann 05-NOV-07
tim 03-JUL-07
tim 14-DEC-07
tim 22-JUN-07
ann 15-MAY-07
Any ideas how to return the name and date of the person with the most recent date?
In this example the query would return 2 rows (one for tim and one for ann).
Thanks for any assistance!

Its more that this is a very simple question to ask on a forum like this.
Reference the comments on Juststarters heavily responded post from earlier today.

How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?

1. How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?
When multiple tables are involved , and the actual number of rows returned is more than what the explain plan tells. How can I find out what change is needed in the stat plan ?
2. Does rowsource statistics gives some kind of understanding of Extended stats ?

You can get Row Source Statistics only *after* the SQL has been executed. An Explain Plan midway cannot give you row source statistics.
To get row source statistics either set STATISTICS_LEVEL='ALL' in the session that executes theSQL OR use the Hint "gather_plan_statistics" in the SQL being executed.
Then use dbms_xplan.display_cursor

Complex QUERY with Variables

I created a complex query to extract data from Journal entry and from Journal voucher. I post here a simplified version where I have deleted UDO references.
I buit it in the Query analizer and it runs ok.
I copied in SAP and it runs ok too.
Now, I need to ask for the start date and end date, as in the first lines of script. But SAP raise an error message I dont understand. I tried to use '[%0]' and '[%1]' insthead of '2008/01/01' and '2008/02/29'

DECLARE @D2 DATETIME

Thank you to everybody for your answers.
I need to know more about this way to declare a variable in SAP.
This is my question:
If I need to filter by date a result from a Union All select, is sufficent to declare the Date Variable for one of the two tables in the Union All?
Following a simple code to explain my dubt:
DECLARE @D1 DATETIME
DECLARE @D2 DATETIME
SET @D1='2008/01/01'
SET @D2='2008/02/29'
SELECT A.ACCOUNT, A.DEBIT, A.CREDIT FROM
SELECT * FROM JDT1
UNION ALL
SELECT * FROM BTF1
) AS A
WHERE A.REFDATE>=@D1 AND A.REFDATE<=@D2
Do you think the WHERE statment will continue to run as well for the Union All in the script main too?
This is the modified initial code:
/*SELECT * FROM JDT1 T0*/
DECLARE @D1 DATETIME
DECLARE @D2 DATETIME
/* WHERE */
SET @D1=/* T0.REFDATE */ '[%0]'
SET @D2=/* T0.REFDATE */ '[%1]'
Thanks in advance,

Complex query

I am novice in PL/Sql. I need some help in writing a complex query.
I imagine the following table structure.
Type(string) Date(date) count(int)
Given a date range
The query needs to group the records on type and return the record (type and count) which has the max date (its just date, no time is involved) for each group (which is based on type) . If there are more than one records which have the max date then the average count should be returned for that type
i would be glad if someone could give any ideas as to how to go about this query. Thanking you in advance.
regards.

Heres the query ... Forget the period .... wht this query is supposed to do is group on assigned ki for a given date range. then it has to get the value which is for the last record for that Ki in the date range. If there are 2 records which have max date then it should give an average.
e.g
assignedKI / date / value
a 1st may 2008 10
b 2nd may 2008 12
c 1st may 2008 13
a 30 - apr-2008 16
b 4th may 2008 17
a 1st may 2008 20
The query should return
a 1st may 2008 15 (which is the average as there are 2 values for the max date for a)
b 4th may 2008 17
c 1st may 2008 13
the following query doesnot work ....
SELECT
kiv2.assigned_k_i,
kiv2.ki_name,
kiv.period,
max( kiv2.ki_value_date) ,
avg(kiv2.ki_value)
FROM
SELECT
assigned_k_i,
period p1,
TO_CHAR(ki_value_date, period) period,
MAX(ki_value_date) ki_value_date
FROM
v_ki_value,
(select ? period from dual)
WHERE
(status = 'APPROVED' OR status = 'AUTOAPPROVED')
AND ( trunc(to_date(to_char(ki_value_date, 'DD/MM/YYYY'), 'DD/MM/YYYY')) >= ?)
AND ( trunc(to_date(to_char(ki_value_date, 'DD/MM/YYYY'), 'DD/MM/YYYY')) <= ?)
AND (INSTR(?, TO_CHAR(assigned_k_i)) > 0)
GROUP BY
assigned_k_i,
TO_CHAR(ki_value_date, period)
) kiv,
v_ki_value kiv2
WHERE
kiv.assigned_k_i = kiv2.assigned_k_i
AND to_char(kiv.ki_value_date, kiv.p1) = to_char(kiv2.ki_value_date, kiv.p1)
GROUP BY
kiv2.assigned_k_i,
kiv2.ki_name,
kiv.period,
kiv2.ki_value
ORDER BY
kiv2.assigned_k_i

Trying to form complex query - need help

I have a fairly complex query that I need to join the results of to show actual and goal by day. The actuals are an aggregation of records that get put in every day, while the targets are a single entry in range format indicating an active range for which the target applies. I'm working on a query that will put things together by month and I'm running into a snag. Can someone please point out where appropriate naming needs to go to get this to come together?
This one works:
(select DATE_INDEX, SUM(LDS) as TTLLDS, SUM(TONS) as TTLTONS from
    (select DATE_INDEX, VEH_LOC, SUM(LDS) as LDS, SUM(WT) as TONS from
       (select c.DATE_INDEX, c.VEH_LOC, COUNT(j.LOAD_JOB_ID) as LDS,
             CASE WHEN SUM(w.SPOT_WEIGHT) = 0 THEN SUM(j.MAN_SPOT_WT)
                  ELSE SUM(w.SPOT_WEIGHT)
              END as WT
          from TC c, TC_LOAD_JOBS j, LOAD_RATES r, SPOT_WEIGHTS w
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX = w.DATE_INDEX and j.LOAD_RATE_ID = w.LOAD_RATE_ID
           and c.VEH_LOC in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
         group by c.DATE_INDEX, c.VEH_LOC
        union
        select c.DATE_INDEX, c.VEH_LOC, COUNT(j.JOB_ID) as LDS,
             DECODE(SUM(j.AVG_SPOT_WEIGHT),0,SUM(r.BID_TONS),SUM(j.AVG_SPOT_WEIGHT)) as WT
          from TC_3RDPARTY c, TC_3RDPARTY_JOBS j, LOAD_RATES r
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
           and j.FACTORY_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
         group by c.DATE_INDEX, c.VEH_LOC)
      group by DATE_INDEX, VEH_LOC)
group by DATE_INDEX)Now I need to add in the following query:
select (u.MACH_TPH_D+u.MACH_TPH_N)/2 as MTPH_TGT, (u.LABOR_TPH_D+u.LABOR_TPH_N)/2 as LTPH_TGT
     from UTIL_TARGET_LOADERS u
    where u.ORG_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)The join needs to be based on VEH_LOC and DAY in the form:
   ... WHERE u.ORG_ID = x.VEH_LOC
          AND x.DATE_INDEX between u.START_DATE and NVL(u.END_DATE,sysdate)I had one that worked just fine when only one entity was involved; the complication arises in that this is a division-level report so I have to individually resolve the subordinates and their goals before I can aggregate. This is one of two queries I need to tie together using a WITH clause so I can pivot the whole thing and present it in month-by-month fashion. When I try to tie it together like the query below, I get: invalid relational operator.
select ttls.DATE_INDEX, SUM(ttls.LDS) as TTLLDS, SUM(ttls.TONS) as TTLTONS, u.TARGET_LTPH, u.TARGET_MTPH

                  ELSE SUM(w.SPOT_WEIGHT)
              END as WT
          from TC c, TC_LOAD_JOBS j, LOAD_RATES r, SPOT_WEIGHTS w
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX = w.DATE_INDEX and j.LOAD_RATE_ID = w.LOAD_RATE_ID
           and c.VEH_LOC in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
         group by c.DATE_INDEX, c.VEH_LOC
        union
        select c.DATE_INDEX, c.VEH_LOC, COUNT(j.JOB_ID) as LDS,
             DECODE(SUM(j.AVG_SPOT_WEIGHT),0,SUM(r.BID_TONS),SUM(j.AVG_SPOT_WEIGHT)) as WT
          from TC_3RDPARTY c, TC_3RDPARTY_JOBS j, LOAD_RATES r
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
           and j.FACTORY_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
         group by c.DATE_INDEX, c.VEH_LOC)
      group by DATE_INDEX, VEH_LOC) ttls
    where ttls.DATE_INDEX beween u.START_DATE and NVL(u.END_DATE,sysdate)
      and ttls.VEH_LOC = u.ORG_ID
group by ttls.DATE_INDEXI know this is a nested mess, as it has to grab the production from two tables for a range of VEH_LOC values and sum and aggregate by day and VEH_LOC, then I have to try and match that to the targets based on VEH_LOC and day. My final query is to aggregate the whole mess of sums and averages by month.
I'd appreciate it if someone can point me in the right direction.

Figured it out.

Complex Query in toplink descriptor

I have a complex query with "Order by" and "Max" aggregation function and I am trying to convert it to a named query. I am using toplink descriptor in Jdeveloper 11G.
1. Is it possible to write a named query which returns values from more than two different table?
2. how to specify Max operation in the Toplink descriptor.
Here is my Query
select * from table1 t1 ,table2 t2
where
t1.id = t2.id and
t1.name ='Name' and
t1.status<>'DELETE' and
t2.a_id = (select max(a_id) from table2 t21 where
t21.a_id = t1.id and
group by id)

TopLink supports sub-selects through sub-queries in TopLink Expressions, and through JPQL. I'm not sure on the JDev support though, you may need to use a code customizer or amendment to add the named query.

First thing that i notice in this query is you are Using Distinct as well as Group by.
Your group by will always give you distinct results ,then again why do you need the Distinct?
For example
WITH t AS
     (SELECT 'clm1' col1, 'contract1' col2,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1' , 'contract1' ,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1', 'contract2',10
        FROM DUAL
      UNION ALL
      SELECT 'clm2', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm3', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm4', 'contract2',10
        FROM DUAL)
SELECT distinct col1,col2,sum(value) from t
group by col1,col2Is always same as
WITH t AS
     (SELECT 'clm1' col1, 'contract1' col2,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1' , 'contract1' ,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1', 'contract2',10
        FROM DUAL
      UNION ALL
      SELECT 'clm2', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm3', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm4', 'contract2',10
        FROM DUAL)
SELECT col1,col2,sum(value) from t
group by col1,col2And also
AND SOL.STATUS_DATE BETWEEN '01-JUN-09' AND '30-JUN-09'It would be best to use a to_date when hard coding your dates.

Refresh table-form query on table only

Hello,
I have a group being generated as a table-form layout. What I would like is for the table page to be refreshed always on entry. I can't set the group requery condition to always, or "when entering the page" as then the view object is executed going navigating from the table page to the form page. This seems a very simple requirement to me but Im struggling to come up with an elegant solution.
Basically what i need is the refreshCondition on the invokeAction binding executable to be "Always and layout=table".
Any help would be greatly appreciated !
Cheers,
Brent

How do you do this, if your current page is a .jsff and not a .jspx? When I look at the refreshCondition, a .jsff does not have access to the facesContext.
Thanks,
Michelle
Since this question was already answered, I created a new thread:

How to store data from a complex query and only fresh hourly or daily?

We have a report which runs quite slow (1-2 minutes) because the query is quite complicate, so we would like to run this query daily only and store in a table so for those procedures that need to use this complex query as a subquery, can just join to this table directly to get results.
However, I am not sure what kind of object I should use to store data for this complex query. Is data in global temp table only persist within transaction? I need something that can persist the data and be access by procedures.
Any suggestions are welcome,
Cheers

Thank you for your reply. I looked at the materialized view earlier on, but have some difficulties to use it. So I have some questions here:
1.The complex query is not a sum or aggregate functions, it just need to get data from different tables based on different conditions, in this case is it still appropriate to use meterialized view?
2.If it is, I created one, but how to use it in my procedure? From the articles I read, it seems I can't just query from this view directly. So do I need to keep the complex query in my procedure and how the procedure will use the meterialized view instead?
3. I also put the complex query in a normal view, then create a materialized view for this normal view (I expect the data from the complex query will be cache here), then in the procedure I just select * from my_NormalView, but it takes the same time to run even when I set the QUERY_REWRITE_ENABLED to true in the alter session. So I am not sure what else I need to do to make sure the procedure use the materialized view instead of the normal view. Can I query from the Materialized View directly?
Below in the code I copied from one of the article to create the materialized view based on my normal view:
CREATE MATERIALIZED VIEW HK3ControlDB.MW_RIRating
PCTFREE 5 PCTUSED 60
TABLESPACE "USERS"
STORAGE (INITIAL 50K NEXT 50K)
USING INDEX STORAGE (INITIAL 25K NEXT 25K)
REFRESH START WITH ROUND(SYSDATE + 1) + 11/24
NEXT NEXT_DAY(TRUNC(SYSDATE), 'MONDAY') + 15/24
enable query rewrite
AS SELECT * FROM HK3ControlDB.VW_RIRating;
Cheers

Creating a complex query in CR designer

I'm running Crystal Reports XI Release 2 on Windows NT. I have a very complex query and cannot figure out how to make it work in CR. Basically, I've got a table A with fields containing reference codes that may or may not be present. I created a SQL query that imbeds select statements in the select fields (the field names between SELECT and FROM). So, it would read something like SELECT field1, field2, (select Code_Name from REF_Table where REF_Table.code=TableA.code and TableA.code is not null) FROM TableA. That works great in SQL Developer.
In CR, I tried a command field but that produces a cartesian set where I get a line for every record that has the field for each and every record in TableA. No good. I just want the name for the value in the TableA record translated to the name if it is present. Is there a way to do this in CR? I used to be able to edit the SQL directly in CR but now it won't let me do that. Anyone know a better way to solve this kind of problem?

I'm not an Oracle guy so I don't know what you can or can't do in PL SQL.
I'm surprised that you are getting different results between SQL Developer and the CR Command. CR should pass the query, exactly as it's written back to the server, same as SQL Dev.
IN T-SQL...If you want to make sure that the sub-query is returning only 1 row, try placing "TOP 1" behind the SELECT.
(select top 1 loc.location_name
from ref_location loc
where loc.location_num=obd.location_num and odb.location_num is not null)
I'm thinking that Oracle doesn't have the the TOP N option but it does have a rownum feature. So maybe...
(SELECT x.location_name
FROM (
    select loc.location_name
    from ref_location loc
    where loc.location_num=obd.location_num and odb.location_num is not null) x
WHERE rownum = 1
ORDER BY rownum)
This is assuming that Oracle allows you to use ORDER BY in a sub-query. T-SQL only allows it if it's used in conjunction with TOP N...
Just a thought,
Jason

Singel Selection in Simple Table

Hi friends
I am not using an advanced table. I am using a simple table (lets say header) with 5 messagestyledtext and a singleselection bean for query purpose which i have created manually. Below this (header), I have an other table (lets say line)
I have some issues which i want to discuss.
1- When i pressed the button to query, my records fetched properly in my header table as i want and it also populates my line table because of View Link. Problem is when my records fetched in header table, my lines table shows me the records pertaining to my first record of header table but my singleselection radio is selected for last record in header table. I am assuming that my viewobjects are working fine but cursor in my table beans are not working fine. Is there any way to reset my cursor in header and lines table according to my viewobjects?
2- since i am using my own custom query panel, I have two button "Go" and "Clear". How can i program my "Clear" button to wipe out the messageinputtext beans in my query panel ?
Since i am very new to OAF, kindly reply me in detail. I read OAF Developer guide but i am unable to understand. If possible then please write the code here.
Regards

Refer
Reset single selection radio to first row of table after execution of query
You can intercept your go button click like follows
On query region we can capture the Go button click and execute our own search along with Standard Search.
OAApplicationModule ap = (OAApplicationModule)pageContext.getApplicationModule(webBean);
OAQueryBean bean = (OAQueryBean)webBean.findIndexedChildRecursive("queryRN");
if(bean!=null)
String id = (String)bean.getGoButtonName();
if(pageContext.getParameter(id)!=null)
//here use the code mentioned in the above forum. (get the first row in VO using vo.first() and set the transient attribute value for the first row to "Y"

I am not sure how many rows you have in the tables but I am assuming that there would be performance benefits in performing the query only once. You can combine similar coding and use an OR condition for the parts that are different. I left the 'K' vin comparison in both years for readability.
I was not able to fully test my code but I believe that it will work as is. I hope it helps. If you are happier with the UNION you may want to investigate the WITH clause as you can query a subset of data twice, rather than the full data set.

Complex Query using findUsers()

I have not run across any posting where the findUsers() or findUsersFiltered() methods were doing anything other than a simple query. Is it possible to do a complex query? For instance, find all users whose status is NOT Deleted. Or all users with a date attribute that is before a given date. Or all users with an attribute value of 'X' OR 'Y'. These are simple SQL queries. I can see how to do a series of simple queries and deal with merging or filtering the results. But wouldn't it be way more efficient to do it in the original query?
If it is possible, can you point me to an example?
Thanks,
Bill

Working with multiple results of a complex query

Hi all!
As I "advance" in learning PL/SQL with oracle, I now get stuck in handling multiple results of a complex query. As far as I know, I cannot use a cursor here, as there is no table where the cursor could point to.
Here is the concept of what I want to do (pseudocode):
foreach result in SELECT * FROM table_1, table_n WHERE key_1 = foreign_key_in_n;
    -- do someting with the resultHere is my attemt, that freezes the browser gui and throws an internal database error:
declare
    type t_stock is record(
            baggage_id baggage.baggage_id%type,
            section_id sections.section_id%type,
            shelf_id    shelves.shelf_id%type
    v_stock t_stock;
    rcnt number(2);
begin
dbms_output.put_line(TO_CHAR(rcnt));
loop
     SELECT COUNT(*) INTO rcnt FROM (
               SELECT baggage.baggage_id, sections.section_id, shelves.shelf_id
               FROM baggage, sections, shelves
               WHERE baggage.baggage_id = sections.contained_baggage_id
                    AND shelves.is_connex_to_section_id = sections.section_id);
     IF rcnt <= 0 THEN
          exit;
     END IF;
     SELECT baggage.baggage_id, sections.section_id, shelves.shelf_id INTO v_stock
     FROM baggage, sections, shelves
     WHERE baggage.baggage_id = sections.contained_baggage_id
          AND shelves.is_connex_to_section_id = sections.section_id
          AND ROWNUM < 2;
     UPDATE sections SET contained_baggage_id = NULL WHERE section_id = v_stock.baggage_id;
     commit; -- do I need that?
end loop;
END;
/So, is there a way to traverse a list of results from a complex query? Maybe without creating a temporary table (or is that the better way?).
regards, Alex
I reformatted the code
pktm

Ok, here are the details:
The tables are used to model kind of a transport system. There are terminals connected with sections that may contain 1 piece of baggage. The baggage is moved by a procedure through a transport system. After each of these "moving steps", I check if the baggage is in front of the shelf it should be in.
[To be honest, the give statement doesn't contain the info, in which shelf the baggage wil bee inserted. That was spared out because of the lack of a working piece of code :)]
But: if we consider the fact, that a baggage is in front of such a shelf in the way, that it should be put in this shelf, then all this makes some sense.
- move baggae through a transport system
- see if you can put baggage into a shelf
In order to "put baggage in a shelf", I need to remove it from the transport section. As the transport system is not normalized, I need to update the section where the baggage was in.
Uhm... yes it's a task that doesn't make too much sense. It seems to be some kind of general spirit in university homework :)
But: the FOR r IN (Statement) lloks good. I'll use that.
And, the ROWNUM < 2 is used to limit the size of the result to 1, there is no need to have a specific ordering. It's just because - afaik - oracle doesn't have a limit clause. I would appreciate your help if you know a better way to do limit resultsets.
best regards, Alex
