If I want to join two table together. I want to search the number of record in IMEI that have N_SIM_STATE =1 in RCA_SMART_CARD . The MSISDN in IMEI is equal to C_SIM_MSISDN in RCA_SMART_CARD .

How can I do and what is the sql statment ??

PL/SQL :: Join Between Table With User Based Content And Base Table

Jul 30, 2012

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
CORE     11.2.0.2.0     Production
TNS for IBM/AIX RISC System/6000: Version 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.

Server Administration :: How To Get Disk List On Any DB Instance That Uses ASM Instance

Mar 16, 2011

My context on our servers is the following one:

- one ASM instance
- X DB instances
- each DB instance uses 2 or more dedicated diskgroups from the ASM instance
- there is one diskgroup named FREEDISK that contains spare disks

On each DB instance you can see:

- the list and global parameters of all diskgroups using v$asm_diskgroup view
- the list and parameters of all disks the instance is using with v$asm_disk view

So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?

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.

SQL & PL/SQL :: Mechanism Of Self Join Table

Jun 11, 2010

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.

SQL & PL/SQL :: Outer Table Join With Not Equal Condition

Aug 20, 2010

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 '<'.)

Query Optimization On Join With A View On Huge Table?

Jun 22, 2011

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.

SQL & PL/SQL :: Filtering Dataset Based On Records Returned By Table Join

Nov 10, 2010

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 ?

SQL & PL/SQL :: Stored Procedure With Multiple Table Join With Aggregate Functions

Jun 15, 2013

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.

SQL & PL/SQL :: Normal Join And Outer Join

Oct 19, 2013

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 ?
