Join query with cfoutput group

Hi,
I have the problem with join query and output the goup by, can anyone helps please?
1: worked fine
<cfquery name="qOrgs" datasource="#GetDSN()#">
select org
from cat
</cfquery>
<cfoutput query="qOrgs" group="org">
#org#<br />
</cfoutput>
2: not work, not grouping and display duplicated.
<cfquery name="qOrgs" datasource="#GetDSN()#">
select org
from user u
inner JOIN cat c
on u.userid= c.userid
</cfquery>
<cfoutput query="qOrgs" group="org">
#org#<br />
</cfoutput>
Thanks

To expand on Dan's answer;
The "group" property of the <cfoutput...> tag is fairly simplistic. All it actuall does is conditionally output content whenever the value of the specified group column changes.
So if you do not use an ORDER BY clause in your SQL to group the values of that column together (or they don't naturally group because of the current state of the data in the database) then the output is probably not going to be as desired.

Left join query with join of three tables

I'm trying to build a query which has me stumped. Most of the query is fairly straightforward but I've run into an issue I'm not sure how to solve.
Background:
We have actions stored in i_action.
We have the available attributes for each type of action. The available attributes for each action are described in shared_action_attribute. Each type of action may have up to three attributes or none at all.
We have the values stored for the attributes in i_attribute_value.
A written example:
We have a transfer action (action_code B4). The entry of the B4 action into i_action records the fact that the transfer occurred and the date on which it occurred. The available attributes for a transfer action are the receiving function code, the receiving unit number, and the transfer reason code. These available attribute types and their order are stored in shared_action_attribute. The actual values of the attributes for a specific transfer action are stored in i_attribute_value.
Now i_action and i_attribute_value can be directly linked through action_seq in i_action and ia_action_seq in i_attribute_value. A left join built between these two tables provides results for all actions (including actions which have no attributes) and attribute values (see query 1 below).
There are two issues. First, I only want the first two attributes. In order to specify the first two attributes, I also have to link i_attribute_value to shared_action_attribute (which is where the order is stored). I can build a simple query (without the left join) linking the three tables but then actions with no attributes would be excluded from my result set (see query 2 below).
The second issue is that I would actually like one row returned for each action with first_attribute and second_attribute as columns instead of two rows.
The final query will be used to create a materialized view.
Here are the tables and examples of what's stored in them:

This is my current query along with its results. Most of it is straightforward select but one column is populated using the last_value analytical function (thanks to you guys).

I found this pretty complex to try to write out - I hope I've been clear.
Thanks so much!

Ok, here's more information with a simplified question. I figured out the syntax for building my query with the three tables. My final query returns multiple rows (multiple attributes per action). Instead of multiple rows, I'd like two columns (first_attribute, and second_attribute) in a single row (I only need the first two attributes).

Query with/without group by returning totally different results

Hi,
I've got this query:
select count(DISTINCT UL.user_id)
from app_user_log UL,
    company_registry CR,
    productarea PA,
    user_registry UR
     where UL.time_stamp >= to_date('04/02/2002','dd-mm-yy')
     and UL.time_stamp <= to_date('10/02/2002','dd-mm-yy')
     and UL.description = 'Open'
     and UR.INT_COMPANY_ID=CR.COMPANY_ID
     and PA.PRODUCTAREA_ID=CR.PRODUCTAREA_ID
     and UL.USER_ID=UR.USER_IDIt returns the value 262
I then want to divide this into one block pr application_id so that I get the number of users with app_id=1 as first applications, the number of users with app_id=2 as first application, and so on..
I thought this would be it:
select ul.application_id, count(DISTINCT UL.user_id)
from app_user_log UL,
    company_registry CR,
    productarea PA,
    user_registry UR
     where UL.time_stamp >= to_date('04/02/2002','dd-mm-yy')
     and UL.time_stamp <= to_date('10/02/2002','dd-mm-yy')
     and UL.description = 'Open'
     and UR.INT_COMPANY_ID=CR.COMPANY_ID
     and PA.PRODUCTAREA_ID=CR.PRODUCTAREA_ID
     and UL.USER_ID=UR.USER_ID
      group by ul.application_idBut this query yields an output with the sum of the counts way above 262 as I would expect..

Approach the problem as you would any programming problem - break it down into simpler problems. Solve each of these logically.
Simplifying here, but you should get the basics of this. For example. We need the earliest time stamp from a table. Then we need to select a distinct list of users and applications for that time stamp.
with EARLIEST_TIME_STAMP as (
select
MIN( datetime_stamp ) AS datetime
from my_table
select
count( DISTINCT userid ) as DISTINCT_USERS,
count( DISTICT applications ) as DISTINCT_APPLICACTION
from my_table t
join EARLIEST_TIME_STAMP s
on s.datetime = t.datetime_stamp

Table joining query with dates

Hello,
I have two tables, one containing a list of pupils, their class start date and their class end dates. The second table contains the address (postcode) history of the pupil. I need to bring these two tables together into one query to show all the classes from the 'pupils' table and add in the most recent postcode of the address prior to the start date of the clasS from the 'addresses' table. I.e. to show where the pupil lived when they started the class.
Could anyone show me how to do this please? I've provided a 'desired' table to show what I need the results to look like.
I hope this is clear, please ask if it isn't - I'm sure this should be simple! But I can't get my head around it. I'm using Oracle 9i and SQL Developer.
Thanks :)

Hi,
That's an example of a Top-N Query , and here's one way to do it:
WITH     got_r_num     AS
     SELECT     p.*
     ,     a.address_start
     ,     a.postcode
     ,     ROW_NUMBER () OVER ( PARTITION BY p.pupil_id
                               ,                    p.class_start
                               ORDER BY         a.address_start     DESC
                       )         AS r_num
     FROM     pupils        p
     JOIN     addresses a ON   p.pupil_id        = a.pupil_id
                     AND p.class_start >= a.address_start
SELECT     pupil_id, class_start, class_end, address_start, postcode
FROM     got_r_num
WHERE     r_num     = 1
;As you can see, the sib-query pairs each pupil and class with all the earlier addresses, and then numbers the addresses such that the latest address_start gets the lowest r_num (that is, 1, since ROW_NUMBER always starts with 1). The main query displays only the most recent address (the one with r_num = 1) for each pupil and class.
Does addresses.address_end plays any role in this problem? For example, would it matter if the most recent address for a given pupil and class had expired before the class started? That is, if we change the middle of address to:
select 'A227'          as pupil_id
,      to_date ('03/08/2011', 'dd/mm/rrrr')
,      to_date ('07/08/2011', 'dd/mm/rrrr')     -- Not 31/10/2011
,      'TW3 ZE3'      as postcode
from      dual would it still count as the last address before the class that started on 08/08/2011?

Hello
It sounds like you need a cumulative sum, in which case I think you'll need to go with analytics. If you could supply create table statements, some sample data and a clear example of the output you expect, it would be easier to put something together. However, I think the statement below should work although it is untested.

Can we put Join Query with Expdp in Query Parameter

Dear All
Can we put join condition like
A.roll_no=B.roll_no
in query clause of EXPDP utility of Oracle 10g.
My parameter file is
INCLUDE=TABLE:"IN ('A','B')"
QUERY ="where roll_no between 1 and 100 "
then it works and export the data. But I want Above condition.
But when I specify it gives ORA-39001 error.
If possible, How and Can you specify example.

Nikhil

Hello,
Please check if OSS note 858458 is applicable in your case.

Join query with inheritance hierarchies

Hi,
I need to execute a query that crosses two different inheritance hierarchies:
1st hierarchy:
class A {
private CA myCA;
class B extends A { ... }
class C extends A { ... }
2nd hierarchy:
class CA { ... }
class CB extends CA { ... }
class CC extends CA {
int i;
As you can see, these two hierarchies are connected at the level of their base classes: an A object is associated to a CA object.
The code in these classes makes sure that a B is always associated to a CB object, and that a C object is always associated to a CC object--i.e. a C object will never be associated to a CA or CB object.
The query I need to execute is the following:
read all C objects for which the i field of the associated CC object is equal to 42.
In JDO I'd say something like this:
"((CC) myCA).i == 42".
How can I do this in TopLink?
Thank you,
Oliver Kamps

Hi Oliver
I worked out a few examples to clarify things a bit.
If the CC Descriptor uses the same table as the CA Descriptor, then you can use a DirectQueryKey on your CA Descriptor:
     public static void amend(Descriptor desc)
          DirectQueryKey key = new DirectQueryKey();
          key.setName("CC_cast_key");
          key.setFieldName("I");
          desc.addQueryKey(key);
After that, the Expression will become:
query.setSelectionCriteria(query.getExpressionBuilder().get("ca").get("CC_cast_key").equal(42));
If the CC info is in a different table then I just used the following Expression:
query.setSelectionCriteria(query.getExpressionBuilder().get("ca").getTable("CC").getField("CC.I").equal(42));
The problem in the latter case is that TopLink needs to make an additional JOIN expression (above and beyond what it would've needed to do if you selecting information available in only the CA descriptor).

Inner join query used with 7 Database tables

HI All,
In a report they used the Inner join Query with 6 Data base table..now there is a performance issue with at query.
its taking so much of time to trigger that query. Please help how to avoid that performance issue for that.
In that 2 database tables containing lakhs of records..
According to my knowledge it can be avoided by using secondary indexs for those 2 database tables..
and by replacing the Inner join Query with FOR ALL ENTRIES statement.
i want how to use the logic by using FORALL ENTRIES statement for this..
So, please give you proper suggestion to avoid this issue..
Thanking you.

Hi,
And what do you mean with "they used"? If "SAP used" then yo will need to ask a SAP for note
FOR ALL ENTRIES is quite good described in help. Please search forum also.
Without query it won't be possible to tell how it can be optimized, however you can try to use SE30/SAT and ST05. Maybe it will help you.

Ora-03114 running a query with group by

Hi, I've a query with a group by on a sub-query, something like
SELECT <40+ fields>
FROM (SELECT <40+ fields>
FROM table
GROUP BY <40+ fields> I don't have any problem running this query directly via toad. This query is a cursor in a procedure in a package and, if I invoke it on the same data, the session crash "with ora-03114 not connected to oracle". If I modify the query selecting less fields, 22, I don't have any problem while with 23 the crash appears.
Furthermore, I don't have any problem in other databases with similar data.
The db version is 9.2.0.6.0 - 64bit
Any idea/advice?

Are there any TOAD non-fetched column values in your result set, i.e. CLOBS, XMLTypes, nested types?
What does your code do with the cursor? Presumably you don't loop through it and do nothing. Are you sure it's the select that's causing the error, or something you are doing with the data in the procedure?
Can you not adding some instrumentation to your code so that you know exactly what line/data values are processed at the time of the crash? Does it always crash on the same values/line or does it vary?
"Furthermore, I don't have any problem in other databases with similar data." ... what do you mean by "similar data". You only need one odd value in one column to cause you a 3114 in the right circumstances. It seems like you are long way off establishing what exactly the problem is. It's always useful not to close doors to lines of thought. You need to systematically track down the root cause of the issue by exclusion and assumptions are the enemy of that process.

CFOUTPUT GROUP ing max results ??

Hello All,
Just a question, is there a max number of rows etc that cold
fusion can handle in outputing by group from a large query?
I have a query that returns 45631 rows in about 5 seconds it
has some joined tables and grouping in the query.
I output the query using two nested groups
CFOUTPUT query="get_data" group="suppname"
Group title
CFOUTPUT group="mpart"
relevant part
CFOUTPUT
all lines from query for that part
/CFOUTPUT
/CFOUTPUT
/CFOUTPUT
My page only seems to output 9999 results when I use GROUP in
the output, but if I just output the query with no GROUPING then I
get all 45631 results.
Does CF have a limit on the results when GROUPING in a
CFOUTPUT?
Kind Regards Guy

How are you counting your outputted results?

MV Incremental Refresh on join query of remote database tables

Hi,
I am trying to create a MV with incremental refresh option on a join query with 2 tables of remote database.
Created MV logs on 2 tables in the remote database.
DROP MATERIALIZED VIEW LOG ON emp;
CREATE MATERIALIZED VIEW LOG ON emp WITH ROWID;
DROP MATERIALIZED VIEW LOG ON dept;
CREATE MATERIALIZED VIEW LOG ON dept WITH ROWID;
Now, trying to create the MV,
CREATE MATERIALIZED VIEW mv_emp_dept
BUILD IMMEDIATE
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE1/(24*15)+
WITH PRIMARY KEY
AS
SELECT e.ename, e.job, d.dname FROM emp@remote_db e,dept@remote_db d
WHERE e.deptno=d.deptno
AND e.sal>800;
Getting ORA-12052 error.
Can you please help me.
Thanks,
Anjan

Primary Key is on EMPNO for EMP table and DEPTNO for DEPT table.
Actually, I have been asked to do an feasibility test whether incremental refresh can be performed on MV with join query of 2 remote database tables.
I've tried with all combinations of ROWID and PRIMARY KEY, but getting different errors. From different links, I found that it's possible, but cannot create any successful testcase anyway.
It will be very much helpful if you can correct my example or tell me the restrictions in this case.
Thanks,
Anjan

Need help in optimizing the query with joins and group by clause

I am having problem in executing the query below.. it is taking lot of time. To simplify, I have added the two tables FILE_STATUS = stores the file load details and COMM table that is actual business commission table showing records successfully processed and which records were transmitted to other system. Records with status = T is trasnmitted to other system and traansactions with P is pending.
CREATE TABLE FILE_STATUS
(FILE_ID VARCHAR2(14),
FILE_NAME VARCHAR2(20),
CARR_CD VARCHAR2(5),
TOT_REC NUMBER,
TOT_SUCC NUMBER);
CREATE TABLE COMM
(SRC_FILE_ID VARCHAR2(14),
REC_ID NUMBER,
STATUS CHAR(1));
INSERT INTO FILE_STATUS VALUES ('12345678', 'CM_LIBM.TXT', 'LIBM', 5, 4);
INSERT INTO FILE_STATUS VALUES ('12345679', 'CM_HIPNT.TXT', 'HIPNT', 4, 0);
INSERT INTO COMM VALUES ('12345678', 1, 'T');
INSERT INTO COMM VALUES ('12345678', 3, 'T');
INSERT INTO COMM VALUES ('12345678', 4, 'P');
INSERT INTO COMM VALUES ('12345678', 5, 'P');
COMMIT;Here is the query that I wrote to give me the details of the file that has been loaded into the system. It reads the file status and commission table to show file name, total records loaded, total records successfully loaded to the commission table and number of records that has been finally transmitted (status=T) to other systems.
SELECT
    FS.CARR_CD
    ,FS.FILE_NAME
    ,FS.FILE_ID
    ,FS.TOT_REC

    FROM COMM
    WHERE STATUS = 'T'
    GROUP BY SRC_FILE_ID
) C ON C.SRC_FILE_ID = FS.FILE_ID
WHERE FILE_ID = '12345678';In production this query has more joins and is taking lot of time to process.. the main culprit for me is the join on COMM table to get the count of number of transactions transmitted. Please can you give me tips to optimize this query to get results faster? Do I need to remove group and use partition or something else. Please help!

I get 2 rows if I use my query with your new criteria. Did you commit the record if you are using a second connection to query? Did you remove the criteria for file_id?

This was an interview question.
Table Names: bookshelf_checkout
bookshelf
And the join condition between these two tables is title
We need to rewrite below query without using join condition and group by clause ?
SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
           FROM bookshelf_checkout bc,bookshelf b
           WHERE bc.title(+)=b.title
           GROUP BY b.title;When I was in college, I read that most of the SELECT statements can be replaced by basic SQL operations (SET OPERATORS). Now I am trying to rewrite the query with SET operators but not able to get the exact result.
Kindly help me on this.
Thanks,
Suri

Something like this?
1 WITH books AS (
2 SELECT 'title 1' title FROM dual UNION ALL
3 SELECT 'title 2' FROM dual UNION ALL
4 SELECT 'title 3' FROM dual ),
5 bookshelf AS (
6 SELECT 'title 1' title, DATE '2012-05-01' checkout_date, DATE '2012-05-15' returned_date FROM dual UNION ALL
7 SELECT 'title 1' title, DATE '2012-05-16' checkout_date, DATE '2012-05-20' returned_date FROM dual UNION ALL
8 SELECT 'title 2' title, DATE '2012-04-01' checkout_date, DATE '2012-05-15' returned_date FROM dual )
9 SELECT bs.title, MAX(bs.returned_date - bs.checkout_date) OVER (PARTITION BY title) FROM bookshelf bs
10 UNION
11 (SELECT b.title, NULL FROM books b
12 MINUS
13* SELECT bs.title, NULL FROM bookshelf bs)
SQL> /
TITLE   MAX(BS.RETURNED_DATE-BS.CHECKOUT_DATE)OVER(PARTITIONBYTITLE)

Set READ UNCOMMITED for a query with a table join (Ver 12.5. and 15.5)

Hi all,
this is an example of how to set the READ UNCOMMITED isolation level for a simple query:
select col_a from mytable at isolation 0
What about a query with an equi-join?
Is it:
select col_a
from mytable t1, mytable t2
at isolation 0
I am sorry for the simple question, I did not find a auitable example in the documentation.
Best Regards
Arthur

Yeah, the docs aren't very good at providing a robust set of examples so you've gotta:
1 - review the command syntax and then
2 - try a few examples until you find the format that works
1 - From the ASE 15.5 Commands reference manual we find the following syntax:
=========================
select ::=
          select [all | distinct]
          [top unsigned_integer]
          select_list
          [into_clause]
          [from_clause]
          [where_clause]
          [group_by_clause]
          [having_clause]
          [order_by_clause]
          [compute_clause]
          [read_only_clause]
          [isolation_clause]
          [browse_clause]
          [plan_clause]
=========================
This shows us that the isolation clause is attached at the 'end' of the query as a query-level specifier (along with the 'group by', 'order by' and 'having' clauses).
From this syntax I'd say your proposed query looks correct so ...
2 - Try running your example to see if you get a syntax error ("When in doubt, try it out!"), eg:
=========================
select s.name,c.name
from sysobjects s, syscolumns c
where s.id = c.id
at isolation 0
go
name
sysobjects
sysobjects
sysobjects
... snip ...
=========================
