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 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]....
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.
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 |

I stumbled about some weird 11gR2 behavior (running on AIX).When I performed a join between a table with user based content (parts belonging to an sourcing scope) and a base table (parts available) whereas the parts have to fulfill a special regular expression, it showed that the same query is faster when using outer join than inner join (about 0.7sec vs. 20sec; which makes me believe that regexp_like works wrong when involved in an inner join).
i tried the same statement with a standard like (but not fulfilling the same condition).This time performance was as expected (inner join outperforming outer join).

I can see it, the execution plan for the "inner join" doesn't show so much more costs than the one for the outer (but why at all is does an inner join cost more?) ...The execution plan for both "not like" is the same and (surprisingly ;-) ) similar to "outer-regexp".
I hope sample data are not needed as there would be needed a lot...this is the second time I came across the "plan worse but execution time better" phenomenon.
I am trying to join column names from a table with data from a different table. I think i should be able to pass the parameter to a 'select list' in a query. Look at my sample data below. And the data in sales table can grow till 15 rows and similarly corresponding columns in saleshist.
I am having trouble retrieving the Max, latest date, from a table with a join to one another table and other fields from both.I was able to get the MAX service_date grouped by id. But once I tried to add more fields to the query and another table it won't work.
Here is what I have:
selectMAX(cs.service_date), cs.notes, cs.applicant_id,wr.program_code,wr.last_name,wr.first_name,wr.region_code,wr.status_cd from cs join wr on cs.applicant_id=wr.applicant_id where wr.status_cd='AC' group by cs.applicant_id

I have a table that contains 15 columns. Say each columns contains name of fruits. And another master table which contains names of valid fruits. Now I have to create another table from these tables such that for each column if the fruit name is present in the master table then fruit-name is populated else "invalid" is populated. I know using left join for 15 times to the same master table can work. But I found this very clumsy. Is there any other way of doing it.This is just a sample case. In real scenario I have a table of 800 million records and master table of 30000 records.
