must generate a Cartesian join, but I do not know why it happens. dt.debtorkey, cl.clientkey, inv.invoicekey, ag.agingkey are primary keys of each table. The problem is: I got same tuple for 8 times.
The requirement is to replicate the bu_id records with bu_id=0 as bu_id=414545 ( there is no lookup available) so the same table should act as a lookup table to populate bu_id for the records where bu_id=0
i.e., here it will replicate for the sku set with bu_id value=0
select a.ccn,b.bu_id,a.sku,b.sku from test_item_bu_id a , ( select distinct ccn,sku_num, bu_id from test_item_bu_id where bu_id in (414545) and CCN in ('M10000') ) b where a.bu_id = 0 and a.sku <> b.sku and a.ccn= b.ccn
How can we avoid the last record, i.e., SKU=600-11437 since it is already having bu_id no need to replicate it, but it is getting replicated since the extra record with bu_id=0 exist for the same sku.
Having production system: 11.2.0.1 on Windows Server x64 Test system: 9.2.0.1 on Windows XP
Problem preface: to get all unique CASEID which should be checked up by biometric system.What i should check - all CASEs for different PERSONs having same PHONEs at least among one phone type (1..4).Real table contains little bit more than 10 million records.I made test scripts.
Below the DDL for test table creation: ------------------------------------------ -- Create CASEINFO test table ------------------------------------------ DROP TABLE CASEINFO; CREATE TABLE CASEINFO
[code]...
Below i've put SQL/DLL to make test data.number of records inserted 2 millions. PERSON_COUNT := #/8; ------------------------------------------ -- fill CASEINFO with sample data ------------------------------------------ DECLARE I INTEGER;
[code]...
Below SQL select to check the data in created table. ------------------------------------------ -- Check test data counters ------------------------------------------ SELECT 'TOTAL',count(*) from CASEINFO UNION ALL SELECT 'LEGAL',count(*) from CASEINFO where
[code]...
The PROBLEM is that i am experiencing HUGE perfomance problems on both test and production systems with that query:
select distinct b.caseid from CASEINFO a, CASEINFO b where (a.person<>b.person) and (a.sex=b.sex) and ( (a.phone1=b.phone1) or (a.phone1=b.phone2) or (a.phone1=b.phone3) or
[code]...
This query takes almost 90 minutes to execute.And i do not know how to avoid this.Full SQL file to make test attached.
I was practicing on Recursive Subquery Factoring based on oracle examples available in the documentation URL....I was working on an example which prints the hierarchy of each manager with his/her related employees. Here is how I proceed.
WITH tmptab(empId, mgrId, lvl) AS ( SELECT employee_id, manager_id, 0 lvl FROM employees WHERE manager_id IS NULL UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees, tmptab WHERE (manager_id = empId) [code]....
107 rows selected.
SQL> However, by accident, I noticed that if instead of putting a comma between the table names I put CROSS JOIN, the very same query behaves differently.That is, if instead of writing
UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees, tmptab WHERE (manager_id = empId)I write . . . UNION ALL SELECT employee_id, manager_id, lvl+1 FROM employees CROSS JOIN tmptab WHERE (manager_id = empId)I get the following error message ERROR at line 4: ORA-32044: cycle detected while executing recursive WITH query
I remember, oracle supports both comme notation and CROSS JOIN for Cartesian product (= cross product). For example
SQL> WITH tmptab1 AS 2 ( 3 SELECT 'a1' AS colval FROM DUAL UNION ALL 4 SELECT 'a2' AS colval FROM DUAL UNION ALL 5 SELECT 'a3' AS colval FROM DUAL 6 ), [code]....
SQL> So if both comma notated and CROSS JOIN have the same semantic, why I get a cycle for the above mentioned recursive subquery factoring whereas the very same query works pretty well with comma between the table names instead of CROSS JOIN? Because if a cycle is detected (ancestor = current element) this means that the product with CROSS JOIN notation is generating some duplicates which are absent in the result of the comma notated Cartesian product.
I created a "Select List" in the Shared Components area as follows:
My goal is to create a shared select list that can be used on any form for a particular Field.
IF :P10_FK_RSTA_CODE is NULL THEN RETURN 'select col_description, col_code_pk from CODE_TABLE where col_active_ind = ''Y'''; [code].....
Which works great, but how can I make the select list work for the same column on a different form? Because :P10_FK_RSTA_CODE is hard-coded in the function, I can't reuse this Function from a different form. (I could rename the Field on every form to the same name, but I'm hoping there is a better way.)
Is there a way I can pass in a variable from the Field Item to make this dynamic where I can use it on any form?
we just installed the patch 10.0.2.0.5 on a 10.0.2.0.3 database and some selects didn't work as before. While changing the select clause, there are different counts.
There are 3 tables:
Detail_1 => MASTER_1 <= Detail_2
MASTER_1 has a primary and an unique Key. The 2 detail tables have FK. Now when selecting only columns from the detail tables (joined with master) we get cartesian selects. If i use one column of the master table in the select clause everything is fine.
I have an attendance table in which we have empno, time_in, time_out..etc.
I want to create a matrix report that should shows all dates of any specific required month in columns and present empno in rows and time_in in cells.
I did it with using a temporary table by filling all the required dates and outer join with attendance table, it works fine, but it takes so long, is there any other better fast way to do it?
I have been told to create a query which should give out the same output as the UI of an exception management application . However , many referenced tables have one to many relationship . I created a query using a function which was giving the required output . But the performance of the query was not good as for each row . Is there a method to create a select using joins to show one to many relationship in a table .
Table Two TableTwoId Name 1 Jones 2 Smith 3 Edwards 4 Camden
My SQL to fetch all records with Smith works great:
select Name from TableTwo Inner Join TableOne on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo) where Name = 'Smith'
Now I need to create an alias for the Name field. Here is my attempt:
select myAliasName from TableTwo Inner Join TableOne on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo), (select Name as myAliasName from TableTwo) where myAliasName = 'Smith'
This attempt pulls up all the records instead of just Smith records. How I can create an alias for the Name field in my above query?
DIDDOB_INFO(VARCHAR2) 34425 Mar 1967 123 12 MAR 1963;25 FEB 1974;25 AUG 1978 46515 FEB 1980
I want to join the columns DOB from table -1 and DOB_INFO from table 2 but the datatype of DOB is DATE and DOB_INFO is VARCHAR. TO_DATE function is not working here.
How to use outer join condition in my below query. In the table APPS_JP.GEDIS_OFFER_HEADER goh I have more records in the table APPS_JP.GEDIS_ORDER_BUILDS gob I have less number of records.
I want all the records from APPS_JP.GEDIS_OFFER_HEADER goh including other conditions. I have tried goh.OFFER_NO=gob.OFFER_NO(+) but same result.
joining this query instead of using the left join. Reason is want to show the score column in a different place and also do not want to show the second IPS column that is used in the joined query.
I saw a strange plan for one query in TESTING DB today. Although 2 tables are involved i dont see any join , NL/HJ/SMJ !! i am not facing any performance issue but curious to know what type of optimization oracle is doing here.
Query text and plan : SELECT FIRST_NAME FROM CAMPA.TABLE_A WHERE NAME_ID = (SELECT NAME_ID FROM CAMPA.TABLE_B WHERE ban=:b1); [code]....
I've seen this example numerous places, and tried to implement it, but I keep getting an "invalid identifier" error message, despite the fact that I've got the table and column specifically identified.For instance, my query reads like:
UPDATE tbl1 SET tbl1.EMPID = (SELECT tbl2.EMPIDA FROM tbl2 WHERE LOWER(tbl1.EMAILCOL) = LOWER(tbl2.EMAILCOL2) ) WHERE tbl2.EMPIDA IN ('Z1O435','S8M4722','M0D5156') AND EXISTS (SELECT tbl2.EMPIDA FROM tbl2 WHERE tbl1.EMAILCOL= tbl2.EMAILCOL2 );
But I'll keep getting flagged at the tbl2.EMPIDA column reference. I have not tried this in SQL Plus, just in TOAD, but it seems to repeatedly fail.I have had to dump records to standalone Access tables and link back to perform the updates.
SELECT v.key$ FROM VERSION_TABLE v, DOCUMENT_TABLE d, CLASS_TABLE z WHERE v.documentKey = d.key$ AND d.classKey = z.key$ AND z.key$ IN (SELECT zz.key$ FROM CLASS_TABLE zz START WITH zz.name = 'esDTTemplate' CONNECT BY PRIOR zz.key$ = zz.parentKey) AND v.ESGROUP = 'SearchOperatorsMapping' ORDER BY d.name
Now I noticed that the subquery is never used to seed the join: indexes - if any - are used. Otherwise a full table scan is performed.In the example - if ESGROUP is indexed, then it's chosen to start the join evaluation. If not, a full table scan is performed.Is there any way to suggest to the optimizer to use the subquery in case there are no indexes - as a fallback ?
In the above example where VERSION_TABLE contains nearly two million records, the no index solution takes 60 secs. vs. less than 1 sec. in the index case.Wrapping the hierarchical query in a inline view leads to same result.
PS: the execution plan (without index) is: ------------------------------------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time ------------------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | | | 9 (100)| | | 1 | SORT ORDER BY | | 1 | 171 | 9 (23)| 00:00:01 | |* 2 | HASH JOIN SEMI | | 1 | 171 | 8 (13)| 00:00:01 |
create table ACTIONARI_ARH ( actionar_id NUMBER(10) not null, id VARCHAR2(20) not null, id_2 VARCHAR2(20), tip VARCHAR2(1), nume VARCHAR2(100), prenume VARCHAR2(100), adresa VARCHAR2(200),
[code]....
and this view
CREATE OR REPLACE VIEW ACTIONARI AS SELECT "ACTIONAR_ID","ID","ID_2","TIP","NUME","PRENUME","ADRESA","LOCALITATE","JUDET","TARA","CERT_DECES","DATA_REGISTRU" Data_operare,"USER_MODIF","DATA_MODIF","REZIDENT" FROM ( select
[code]....
The table has about 30 milion records and holds persons names, addresses, personal id (id), and internal id(actionar_id) and date when a new adress has been added.
The view is about getting only the most recent info for one person (actionar_id).
if i run a
a) select * from actionari a where a.actionar_id = 'nnnnnnn', result is returned immediatly, oracle uses index and does not do a full table scan.
b) select * from actionari a where a.actionar_id in ('nnnnnnn','mmmmmm','ooooooo'), result is returned immediatly, oracle uses index and does not do a full table scan.
my problem when i use this view in a join.let's assume i have another table with no more than 500 records, something like
create table SMALL_TABLE ( actionar_id NUMBER(10) not null, ...... );
and if i run
select * from SMALL_TABLE s join actionari a on a.actionar_id = s.actionar_id;
it takes like forever to process, forever means 1~3 minutes.by looking at the execution plan, oracle does a full table scan, creates the view for all unique 7milion persons, and only then joins the result with the actionar_is's in the small table and returns the desired 500 record result.i am using oracle 10g.

I have two tables : oa_membership_dtl(in this created_by field is varchar2(200 byte) ,oa_partner_usr_dtl(in this table partner_userid is number(8,0) i need to do join on above fields.
I am using following two queries:
select * from oa_membership_dtl membership join oa_partner_usr_dtl partner_user on to_char(partner_user.partner_userid,'9999')=membership.created_by select * from oa_membership_dtl membership join oa_partner_usr_dtl partner_user on rtrim(ltrim(partner_user.partner_userid||' '))=rtrim(ltrim(membership.created_by))
by using first data is not fetched but 2nd is working fine , i am getting the matched records using 2nd query.
