Simplify the query by using Analytics
Hi gurus,I need to humiliate you help by simplifying the application, as shown below:
with REC_GRP_CNT as (select round (count (*) / 3) HML_CNT of JJVC_ACTIVITY_FREQ_RECENCY).
REC_RANK as
(select a.*, rownum rn of)
Select custid, ((total_edm_opened/total_edm_delivered) * 100) percentage from JJVC_ACTIVITY_FREQ_RECENCY by 2 desc) a).
FREQUENCY_HIGH like)
Select custid, 'H' rec_rank FREQUENCY_RANK where rn < = (select HML_CNT FROM REC_GRP_CNT)).
FREQUENCY_MEDIUM like)
Select custid, I ' rec_rank a FREQUENCY_RANK
where
not exist (select custid from b FREQUENCY_HIGH where b.custid = a.custid)
and rn < = (select HML_CNT * FROM REC_GRP_CNT 2)).
FREQUENCY_LOW like)
Select custid, 'L' rec_rank a FREQUENCY_RANK
where
not exists(select * from)
(select custid from FREQUENCY_HIGH
Union of all the
custid SELECT of FREQUENCY_MEDIUM p) WHERE the p.custid = a.custid)
and rn > = (select HML_CNT * 2 OF REC_GRP_CNT))
Select * from FREQUENCY_HIGH
Union of all the
Select * from FREQUENCY_MEDIUM
Union of all the
Select * from FREQUENCY_LOW
Thanks in advance,
BTF
You are going to have to explain what you mean by
Total records H=33.3%
Total records M=33.3%
Total records L=33.4%
What criteria do you use to create these "buckets" that fall under the data?

Question related to the execution of the query by using the links to the DB
Hi all
I have a source and target database. Both are 11.2.0.3.
I have a query that is running on the source database and load data into the target database.
I created synonyms in the target for all of the tables referenced in the query, remaining at the source.
I run the query in the target using synonyms that I created. I see that the entire query became transferred to the source database and executed. The execution plan of the source was exactly the same as the way in which we could, if the query has been run directly there.
No problems so far.
Now, I have a database from different sources. Version 11.2.0.4.
When I try to mimic the same behavior using this data source, the complete query will NOT be transferred to the source. He made on the source (remote site) full table scans, transfer of data to the target (local site) and then by performing sort operations & the index range scans (min/max) on the target.
In both cases, all of the tables referenced in the query are accessible through the link in the DB.
Please let me know if there is no setting of database / everything which could control how or where a query with all accessible by link DB tables are optimized and executed? Ideally, I want the entire query to be transferred to the remote and executed site.
I can provide more details if necessary.
Thanks in advance.
Thank you sol.beach. Queries I tried both sources are in fact different. I failed to mention that.
@John,
We did recommend the creation of a view of the source, which is synonym on target and run the query. The client was not ready to create any object on the source system and so to test this workaround solution.
********************************************
After some time, I realized that there is a hardcoded as SYSDATE column. Whenever I took it / I did as null, because the entire query is getting transferred to the source DB.
"I changed 'SYSDATE column-name' to ' col_name (select SYSDATE from dual@remote_db_link). But this also seems to stop the query to be sent to the remote db as a whole.
Try to work around this problem, but any ideas are much appreciated.

Hi gurus
I have the following data:
Drop table
DROP TABLE lb_source;
DROP TABLE lb;
Insertion and table creation
CREATE TABLE lb_source
(
source_cd VARCHAR2 (5));
INSERT INTO lb_source
(
SELECT 'a' STARTING from two
UNION ALL
SELECT 'b' double
UNION ALL
Select 'l' to double
);CREATE TABLE lb
(
group_number VARCHAR2 (10),
source_cd varchar2 (5)
);INSERT INTO lb
(
SELECT '100', 'l' FROM dual
UNION ALL
SELECT '100', double null);
------------
If you see table lb then it contained a line with source_cd = l against 100 and source_cd = Null group against group 100, now I want to create this kind of query, in which all correspondence lines in tables to join both if lb is null, then query join all the source_cd of table lb_source except source_cd = 'l '. So far, I created the following query and its works ok but I want to do all my work in one in where condition...
Query
SELECT * FROM
(
SELECT s1, s2 b.source_cd A.source_cd
OF lb_source A
lb b
WHERE A.source_cd = nvl (b.source_cd, A.source_cd)
)
WHERE s2 IS NULL
;
Result
s1 s2
a null value
b zero
l null
Please guide
Hello
So, you want something that produces the same accurate results as the query you posted, but does more just; Isn't it?
Here's one way:
SELECT ls.source_cd S1
NULL AS s2
OF ls lb_source
JOIN lb l WE l.source_cd IS NULL
AND ls.source_cd IS NOT NULL;
I'm curious; What is the business problem that requires this request? What tables and columns represent, and what tell you the query?
Thanks for posting the CREATE TABLE and INSERT statements; It's very useful!

compose the query without using the query designer
New on this BEEP 10.1.3.4.1 product,
questions
1. is there a way to compose a query without using query builder but still has a way to see the result of the query under the PIF?
2. How is - a to compose a query prompt? I know that I can create parm after you create the data set, but at the stage of all data already call you query prompt as where employee id =? E_ID? or just not where clause
Sorry if these questions are too rudimentary, but I did not see that what we have answered according to the user's guide.
Thank you.

Need help to resolve the query by using analytic functions
Hello
I need help to solve this problem, I tried an analytical function but could not solve the problem.
I have three table as illustrated below the table is filled with a flat file. The records are arranged sequentailly based on the name of the file.
The first record of the game based on EIN goes to TAB_RCE
the following records then goes to TAB_RCW
and last save of the game based on EIN goes to the RCT table
How can I make groups and
assign a
EIN * 12345 * line number * 02, 03, 04 * in the table TAB_RCW and * 05 * in the table TAB_RCT
EIN * 67890 * line number * 07, 08, 09,10 * in the table TAB_RCW and * 11 * in the table TAB_RCT
and so on...
Thank you

Slow index by using the query. Fast with full table Scan.
Salvation;
(Thanks for the links)
Here's my question correctly formatted.
The query:
Works on 32 seconds!SELECT count(1) from ehgeoconstru ec where ec.TYPE='BAR' AND ( ec.birthDate <= TO_DATE('2009-10-06 11:52:12', 'YYYY-MM-DD HH24:MI:SS') ) and deathdate is null and substr(ec.strgfd, 1, length('[CIMText')) <> '[CIMText'
Same query, but with an extra where clause:
This is 400 seconds.SELECT count(1) from ehgeoconstru ec where ec.TYPE='BAR' and ( (ec.contextVersion = 'REALWORLD') --- ADDED HERE AND ( ec.birthDate <= TO_DATE('2009-10-06 11:52:12', 'YYYY-MM-DD HH24:MI:SS') ) ) and deathdate is null and substr(ec.strgfd, 1, length('[CIMText')) <> '[CIMText'
It should return data from a table, given the conditions.
The database version is Oracle9i Release 9.2.0.7.0
These are the parameters relevant for the optimizer:

Published by: PauloSMO on November 17, 2009 07:38 - title changed to be more correct.Although your optimizer_mode is choosing, it seems that there are no statistics collected on ehgeoconstru. The absence of estimated costs and estimated row counts of each of the stages of the plan and the "Note: optimization based on rules" at the end of these two plans would tend to confirm this.
Optimizer_mode choose means that if statistics are collected then it will use the CBO, but if no statistic is present in any of the tables in the query, the optimizer to rule will be used. The RBO tends to be happy in the best of the index case. I guess the index ehgeoconstru_VSN contextversion as the main column and also includes the date of birth.
You can either gather statistics on the table (if all other tables have statistics) using dbms_stats.gather_table_stats, or suggest the query to use a full scan instead of index. Another solution would be to apply a function or an operation against the contextversion to prevent the use of the index. something like this:
SELECT COUNT(*) FROM ehgeoconstru ec WHERE ec.type='BAR' and ec.contextVersion||'' = 'REALWORLD' ec.birthDate <= TO_DATE('2009-10-06 11:52:12', 'YYYY-MM-DD HH24:MI:SS') and deathdate is null and SUBSTR(ec.strgfd, 1, LENGTH('[CIMText')) <> '[CIMText'or maybe UPPER (ec.contextVersion) so that would not change the rows returned.

Join the query - confused behavior
Hello.. I need to make a join on four tables and select one data tables. The query is as below,
SELECT THE VIRTUAL MACHINE. SEGMENT, VM.CA, VM. PR, VM. BP, VM. TERM_ID, VM. TL v_mlr_cable VM, v_neicode NEI, v_mlr MLR, v_fibre_ntwk_type FIBER WHERE MLR.master_key = 62 AND MLR.dslam_tid = NEI.id AND NEI.type = 'OLT' AND MLR.ntwk_type = FIBRE.id AND MLR.master_key = VM.master_key;
This query works very well. I want to change the query to have an OR condition by combining certain conditions in the WHERE clause as below,
SELECT THE VIRTUAL MACHINE. SEGMENT, VM.CA, VM. PR, VM. BP, VM. TERM_ID, VM. TL v_mlr_cable VM, v_neicode NEI, v_mlr MLR, v_fibre_ntwk_type FIBER WHERE MLR.master_key = 62 AND ((MLR.dslam_tid = NEI.id ET NEI.type = 'OLT') or MLR.ntwk_type = FIBRE.id) AND MLR.master_key = VM.master_key;
This translates into several duplicates of the correct result lines (about 93 272 rows).
I suspect this is a unwanted Cartesian product.
I am limited to use a 'different' because my application performs custom, so 'distinct' query analysis is out of the option.
I struggle to understand the result of this query. You can help... ! Thanks in advance.
My database: Oracle Enterprise Edition 10.2.0.2.0
Published by: vanessa on June 9, 2011 12:49 AMHello
Can hide you the SELECT DISTINCT in a subquery, like this:
SELECT * FROM ( SELECT DISTINCT VM.SEGMENT, ... );or in a view?
If this is not the case, use GROUP BY. The GROUP BY clause contains all the columns in the SELECT clause.
You could also re - write the query to use EXISTS or IN, instead of a jon.
For example:SELECT SEGMENT , CA , PR , BP , TERM_ID , TL FROM v_mlr_cable vm WHERE master_key = 62 AND EXISTS ( SELECT 0 FROM v_neicode NEI , v_mlr MLR , v_fibre_ntwk_type FIBRE WHERE MLR.master_key = vm.master_key AND ( ( MLR.dslam_tid = NEI.id AND NEI.type = 'OLT' ) OR MLR.ntwk_type = FIBRE.id ) ) ;Do you think it is easier to read and understand the code formatted, as the query above, or unformatted, as what you posted?
Who do you think will encourage people to read your question and provide accurate responses?
Never write, not to mention NPA, not formatted.I hope that answers your question.
If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions) of all the tables and the results desired from these data.
Explain how you get these results from these data.
Always tell what version of Oracle you are using. -

'Function SQL Query return' using with Flash graphics
I created a pl/sql function that returns a SQL query in a varchar2 of this form:
Select the null link
-value > < x value
< value y of Series1 > series 1 label
< value Series2 y > 2 series label
< value of y Series3 > series 3 Label
...
...
from tablea a
Join tableb b
On a.col = b.col
order of < x value >
If I call the function of a graphic Flash box series SQL with the Type of Source query "SQL query" value that returns the function like this:
return functionname (to_date ('30-sep-2010, ' mon-dd-yyyy ""))
It parses correctly and the page is saved; However, when I run the page I get no output - error messages or another indication of a problem.
Now, if I call the function in a SQL client, capture the result of the query SQL using the dbms_output and paste that into the box graphic Flash series SQL - change the Source Type of SQL query query - and save the page it works fine when I run it and returns a chart series flash.
Can anyone suggest either;
1. what I might have missed or done wrong?
2. a way to effectively diagnose the problem...
I tried to use the debugger Apex - what is very nice, indeed - but it provides no information on what might be my problem. I tried to write my own my function debug messages using the apex_debug_message package - nothing...
Thank you
EricHi Eric,.
Try to pull the source like this:
begin return functionname(to_date('30-sep-2010', 'dd-mon-yyyy')); end;This works very well for me, and if I take the begin-end and the final semicolon from the return statement I get the same behavior as you.
He doesn't mention in aid of the source (only during the wizard if) this source type must be expressed in this way, but I agree, it would be useful that the tool would validate to this format meets it "Query SQL that returns the function" or give some sort of indication of the sentence. In any case, this should help you will again.
Hope this helps,
JohnIf you find this information useful, please do not forget to mark the 'useful' or 'correct' post so that others benefit as well.

How to simplify this query in sql simple select stmt
Hello
Please simplify the query
I want to convert this query in a single select statement. Is this possible?
If uarserq_choice_ind is not null then
Select ubbwbst_cust_code

Where utrchoi_prop_code=ubbwbst_cancel_prod
Else
Select max(utvsrvc_ranking)
From utvsrvc,ubbwbst
Where utvsrvc_code=ubbwbst_cancel_prod
End ifSelect ubbwbst_cust_code as val From ubbwbst,utrchoi Where utrchoi_prop_code=ubbwbst_cancel_prod AND uarserq_choice_ind is not null union all Select max(utvsrvc_ranking) as val From utvsrvc,ubbwbst Where utvsrvc_code=ubbwbst_cancel_prod and uarserq_choice_ind is nullWithout more information, we are unable to combine the two queries in 1 without a union.
Looks like you select values totally disperate of totally different tables -
help to try to simplify the form table, based on the collection using dynamic measurements
Hi everyone, I have tried cleaning and simplify an application designed in 2008 apex 3.2. We have improved in 4.1.2 and want to take advantage of our understanding of the apex and the dynamic measures to simplify a large part of our code, get rid of the redundancies and make it easier for the programmer to debug and improve next.
The application is for traders and commercial fishermen and currently has around 4100 users.
The part that I'm trying to simplify is a tabular report, based on a collection. Almost all areas in this tabular form has a logic linked to it... and in most cases, it is superfluous in that it executes a UPDATE_MEMBER on the collection. I would like to remove as much of javascript and additional processes as possible. I'm also still very new to jQuery and javascript, and faced with the two... but competent in pl/sql.
tabular query is:
{code}

I am slow at first and just try to replace the ONCHANGE for apex_item 41 (retail price). I hope that finally replace all the onblur/onchange to use the same dynamic action.
The ONCHANGE for apex_item 41 is currently:
{code}
function setSalePrice (pRow, savePrice)
{
get var = new htmldb_Get (null, & APP_ID., 'APPLICATION_PROCESS is saveSalePrice', 0);
Get.Add ('SETVALUE3', savePrice);
Get.Add('ATTRNBR3','41');
Get.Add ('SEQUENCEID', Prow);
gResult = get.get ();
}
{code}
the saveSalePrice application process is:
{code}
Start
apex_collection.update_member_attribute (p_collection_name = > 'SPECIES_COLLECTION',)
p_seq = >: SEQUENCEID.
p_attr_number = >: ATTRNBR3,.
p_attr_value = >: SETVALUE3);
end;
{code}
I created two new hidden fields: P110_ID and P110_VALUE.
I created a dynamic action: CHANGE COLUMN
event: change
selection type: jQuery Selector
jQuery Selector: input [name = "f41"]
real action 1 - records P110_ID with javascript expression: this.triggeringElement.id
real action 2 - P110_VALUE value with javascript expression: this.triggeringElement.value
true action 3 - run pl/sql code
{code}
declare
number of v_member;
number of v_seq;Start
v_member: = TO_NUMBER (SUBSTR (: p110_id, 2, 2));
Select ltrim (substr(:p110_ID,5,4),'0 ') in the double v_seq;safis_collections.update_column (v_seq,
v_member,
(: p110_value);
end;{code}, where safis_collections.update_column is a package of db
{code}
Procedure update_column ()v_seq in varchar2
v_attr in number ,
v_value in VARCHAR2 )
is
Start
apex_collection . update_member_attribute()p_collection_name=> 'SPECIES_COLLECTION'
p_seq = > v_seq ,
p_attr_number = > v_attr ,
p_attr_value = > v_value );
apex_debug . message ()'put a day of column.seq ='| v_seq || 'attribute =' || v_attr || "with" || v_value );
end ;
{code}
real action 4 - refreshment area
I modified the query in a table to reference apex_item 41 to be
Decode(C020,'Y',apex_item.) Text (41, TO_NUMBER (c041), 5, null), 'No,' N/a ') Sale_Price in the hope that it would fire the dynamic action. I get the below error. The value of P110_ID is null, the value of P110_VALUE seems to be correctly set.
call returned Ajax Server ora error-sequence of 20103:member does not work
There are in the collection 'SPECIES_COLLECTIO' application to run PL/SQL codeI appreciate all thoughts/help on this.
Thank you, Karen
AHHA. change the query to
Decode (c050, 'Y', apex_item.textarea (28, c028, 3, null, null,,'f28_'| seq_id, cm), ' n ',' n/d "") explanation,.
and that did the trick. On the next item.
