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 :: 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.

Performance Tuning :: Select Distinct From Cartesian Join

Sep 12, 2011

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.

SELECT DISTINCT On Multiple Columns

Sep 17, 2010

I've read so many different pages on this topic but I can't seem to get my query the way it needs to be. Here's the query:

select admitnbr, lastname||', '||firstname||' '||finitial, hphone, mobile, wphone, med_rec, dob
from patients join schedule using (key_patien)
join adtmirro using (key_patien)
where appt_state = 'ON HOLD'

Because patients in my database can have multiple appointments "on hold" there are duplicates in the results. I only need 1 record per patient in order to forward this information into an automated dialer to contact that patient. I do NOT want to call the patient over and over again. Once will suffice. I'm trying to make a distinction on the column 'med_rec'. One row per 'med_rec' will be awesome but I can't find a way to create a distinct on that column.

SQL & PL/SQL :: JOIN For Multiple Tables

Mar 29, 2011

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

SQL & PL/SQL :: Splitting One Row In Multiple Rows Based On QTY And Join

Sep 14, 2012

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

SQL & PL/SQL :: Count Distinct Rows In Table

Feb 21, 2013

I think this is easier than I think but all I want to do is count the distinct rows in a table.

WITH data AS
(SELECT 1 id1, 1 id2, 111 val1
FROM dual
UNION ALL
SELECT 1, 2, 222
FROM dual
UNION ALL

[Code]..

seems to get what I want

ID1VAL1CNT1
111114
212224
321114
422224

but can the count be done in a stand alone query such as??

SELECT DISTINCT id1,
val1,
COUNT(*) over() cnt1,
COUNT(*) over(PARTITION BY id1) cnt2
FROM data
ORDER BY id1, val1

NOT what I want

ID1VAL1CNT1CNT2
1111152
2122252

SQL & PL/SQL :: De-normalizing A Log Table And Counting Distinct Rows?

Oct 6, 2011

I have a table in which I can see via which communication channel we have previously communicated with our customers on different dates.

customer_interaction_log (I removed the date column)

customer_id channel
------------------------
1 SMS
1SMS
1SMS
1Email
1Email
2SMS

My goal is to have a de-normalized summary table in which total communication volume for each distinct channel is displayed per customer.Briefly, I would like to reach the following output

customer_interaction_summary

customer_id sms_countemail_count
-----------------------------------
132
210 (or null)

When I run the sql below I am not able to de-normalize by customer id; counts are accurate.

SELECT distinct cil.customer_id,
(CASE channel WHEN 'SMS'
THEN (SELECT COUNT (channel) FROM customer_interaction_log cil1
where cil1.channel='SMS' and cil1.customer_id=cil.customer_id) END) SMS_COUNT,
(CASE channel WHEN 'Email'
THEN (SELECT COUNT (channel) FROM customer_interaction_log cil2
where cil2.channel='Email' and cil2.customer_id=cil.customer_id) END) EMAIL_COUNT
FROM customer_interaction_log cil;

Output:

customer_id sms_countemail_count
-----------------------------------
1 3
21
1 2

I am trying to have one row per customer, however as you can see above it is not the case.

CREATE TABLE CUSTOMER_INTERACTION_LOG (
CUSTOMER_ID NUMBER(2),
CHANNEL VARCHAR2(10 BYTE)
);
Insert into customer_interaction_log (CUSTOMER_ID, CHANNEL) Values (1, 'SMS');
Insert into customer_interaction_log (CUSTOMER_ID, CHANNEL) Values (1, 'SMS');

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.

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

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.
