SQL & PL/SQL :: Multiple Join To Same Table
Apr 12, 2010
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.

I have 2 tables order_items and items.
Order_items Items
Item_id Item_id
Quantity Price
In normal sql statement: select sum(order_items.quantity*items.price) sales_price
from order_items,items
where order.item_id=items.item_id;
I have to put this logic in either a stored procedure or Function just to calculate sum(order_items.quantity*items.price) and store the aggregated value as Sales_price in DB. Then we have to call this from Informatica Stored procedure Transformation where we will have only one output port as Sales_price,this is to load into summary table. All the aggregate calculations and joining of 2 tables should be done on DB side and only one output should be populated when we execute this procedure.

Here is what I'm trying to do:
I have three tables:
TABLE1 TABLE2 TABLE3
NCI 1AB OPEN
NCI (NULL) (NULL)
INV (NULL) (NULL)
NCI 2AB REOPEN
What I want to do is to return all of the rows from TABLE1 that are NCI regardless, and if they are NCI, I want to return the corresponding records from TABLE2 and TABLE3.
If TABLE1 has a record of NCI but there are no corresponding records in TABLE2 or TABLE3, then of course the columns for TABLE2 and 3 would be blank.
I can get all of the NCI records from TABLE1 when I LEFT JOIN with TABLE2, but when I try to specify TABLE3 in the FROM statement, only the records that are NCI in TABLE1 AND have data in TABLE2 are returned, not just all records with NCI in TABLE1.
Let me know if I can further clarify.
I know that you do not have access to my tables, but here is an example of my code so that you may understand my quandary further:
SELECT l.sku AS "SKU",
l.loc AS "LOC",
l.qty AS "QTY",
o.ncikey AS "NCI",
r.description AS "NCI DESC",
o.qtyexpected AS "NCI QTY EXP",
o.qtyreceived AS "NCI QTY REC",
o.loc AS "NCI LOC",
o.status

I am trying to insert records in multiple tables. I know how to view data using joinig, but unable to understand how to insert records in multiple tables using Joining. I searched it on net, but didn't find much. I have also tried to write a code, but it is not working, I have seen some examples on different websites where people are using SELECT in INSERT statement for joining. What is the correct Syntax to INSERT record in Multiple tables.
Insert into library_users, library_users_info
(library_users.username, library_users.password, library_users_info.address, library_users_info.phone_no) VALUES (...)

I need to join ISSUED_REMOVED Table with ITL Table. having each quantity each row.
Eg. If a unit Serial no '354879019900009' has a part (1015268) issued 8 times and then unissued 4 times so finally the part was issued 4 times. so I need 4 rows to show for each qty 1 for that part and unit serial number.
-- ITL Table
Create table ITL_TEST (
ITEM_SERIAL_NO, ITEM_BCN, ITEM_ID, ITEM_PART_NO, OPER_ID,
ISSUED_REMOVED_PARTNO, ISSUED_REMOVED_QUANTITY, QUANTITY, SHIPMENT_ID)
[code]....
-- Issued Removed table
create table ISSUED_REMOVED_ITEM
(REPAIRED_ITEM_ID, ISSUED_REMOVED_ITEM_ID, ISSUED_PART_ID, OPER_ID, ISSUED_REMOVED_QUANTITY)
as select
122013187, 1323938, 1015268, 308, 2 from dual union all select
122013187, 1323939, 1015269, 308, 2 from dual union all select
122013187, 1323940, 1015268, 308, 2 from dual union all select
[code]....
-- The way I need to join the Issued_Removed Table
select * from ITL_TEST ITL
left join
issued_removed_item iri
on iri.REPAIRED_ITEM_ID = ITL.ITEM_ID --ITL.ITEM_ID --rlsn2.item_id --126357561
and iri.oper_id = 308 --in ( 308, 309)

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).
Oracle version information
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
PL/SQL Release 11.2.0.2.0 - Production

NLSRTL Version 11.2.0.2.0 - Production
[code]...
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.
CREATE TABLE SALESHIST
(
PRODUCT VARCHAR2(30 BYTE),
Q1 VARCHAR2(30),
Q2 VARCHAR2(30),
Q3 VARCHAR2(30),
Q4 VARCHAR2(30)

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

I am attempting to select back multiple values for a specific key on one row. See the example below. I have been able to use the sys_connect_by_path to combine the fields into one field but I am unable to assign them to fields of their own. See the example below
TABLE DETAILS:
Policy id plan name
111 A Plan
111 B Plan
111 Z Plan
112 A Plan

Explain the mechanism of this sql statement. I tried to understand how it goes but I really got confused.
select e.last_name, m.last_name mgr
from employees e join employees m
on (e.manager_id = m.employee_id)
The first line seems clear to me that will bring the names of employees and second column will bring names of managers. Second line is clear as well, but the third line couldn't understand. in my mind it should be like that
m.manager_id = e.employee_id
I tired this but doesn't work so what happened exactly in that full statement, I mean how it will match. I just want to understand the mechanism.

I've created a query so I can easily compare two sets of data for two different instruments:
select a.CalId, a.AtName, a.NRef, a.VaLoat, a.ValTime, a.ValRing,
cvs.NRef, cvs.CalId, cvs.AtName, cvs.VaLoat, cvs.Valtime, cvs.ValRing
from CalcAttribute a, CalcAttribute cvs
where a.NRef like '438815' and cvs.NRef like '438813'
and a.CalId *= cvs.CalId
and a.AtName *= cvs.AtName
union
[Code]...
This works great - however I want to add an addtional condition, basically so it only returns where the two are not equal.
I thought I should just be able to add an extra:
and a.ValLoat *<> cvs.ValLoat
and a.ValLoat <>* cvs.ValLoat
But it doesnt seem to like this (Incorrect syntax near '<'.)

I have this table
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 need to work on this requirement.
There are FOUR tables ( T1 , T11 & T2, T22) ALL store order information.
One of four conditions are possible for each Supply Reorder Number:
•Both table queries return no records
oPopulate all the output fields with nulls
•T1 returns a record, but T2 returns no records
oPopulate output fields with values from the join of T1 and T11.
•T1 returns no records, but T2 returns one record
oPopulate output fields with values from the join of T2 and T22.
•T1 returns a record, and T2 returns a record
oIf the latest order is in T1, then populate output fields with values from the join of T1 and T11.
oIf order dates are equal from both join results, then populate output fields with values from the join of T1 and T11 .
oIf the latest order is in T2, then populate output fields with values from the join of T2 and T22.
How do we filter the dataset based on result of table join ?

Lets say I have three tables t1 and t2 and t3.
SELECT * FROM T1;
Id
____
1
2
3
4
SELECT * FROM T2;
Id
____
1
SELECT * FROM T3;
Id
____
1
Now when data exists in T2 and T3, I want to return only the records in T1 that match the records in T2 and T3 which is basically a normal join
select t1.id from t1, t2,t3 where t1.id = t2.id and t1.id = t3.id
However when there are no records in T2 or T3, I want to return all records in T1 i.e 1,2,3,4
One way of doing that is using the not exists clause
select * from t1 where not exists ( select null from t2 where t2.Id != t1.id) and not exists ( select null from t3 where t1.Id != t3.id)
Is there a better way of doing this in sql ?

I would like to know the following.
If multiple queries are run in parallel(at the same time) against a table or a set of tables (query referencing multiple tables), does it reduce the performance.
In other words is Oracle capable of reading (selecting from) the same table multiple times in parllel.
