PL/SQL :: Table With Union All And Using Having Statement?
Sep 18, 2012I am writing a query and I did get it to work but it shouldn't be this hard, I feel like I am doing something wrong, and there has to be a more elegent solution.
This query works:
SELECT a.d
FROM (
SELECT S_ID a, LOOKUP_DESC d, S_CODE f
FROM SSS
JOIN LOOKUP ON S_CODE LIKE LOOKUP_CODE
UNION ALL
[Code]...
I feel like I should be able to execute the query like this: This query doesn't work:
SELECT a.d
FROM (
SELECT S_ID a, LOOKUP_DESC d, S_CODE f
FROM SSS
JOIN LOOKUP ON S_CODE LIKE LOOKUP_CODE
[Code]...
-- not some huge query
SQL & PL/SQL :: Performance With Union And Global Temp Table
May 24, 2010I have a view, which has a union. (Union is required because of the nature of the data fetched). THis view is later joined with a global temp table which holds the -say employee Id the user selects.
So at runtime there is a join with the global temp table and the view. But the performance is really bad. I have tried using various hints, like materialize, /*+ CARDINALITY(gtmp 1) */ etc.
When i query the view alone,. the performance is good. When I remove the union, the performance is good. Some how with the union- there is a full table scan on one of the joining tables.
SQL & PL/SQL :: UNION ALL - View With Similar Indexes Each Table?
Jul 5, 2012I have this sql (generated by discoverer plus), and work fine:
SELECT COUNT(o10475761.SUC_ID)
FROM GAR_DW.ARTICULOS o10475528,
GAR_DW.EMPRESAS o10475602,
GAR_DW.L_DIA o10475639,
[code]...
We need change the table stock_por_sucursal for a view like this, with similar indexes each table
select * from stock_por_sucursal_old
union all
select * from stock_por_sucursal_new
and the result is not good:
SQL Statement from editor:
SELECT COUNT(o10475761.SUC_ID)
FROM GAR_DW.ARTICULOS o10475528,
GAR_DW.EMPRESAS o10475602,
GAR_DW.L_DIA o10475639,
GAR_DW.V_STOCK_POR_SUCURSAL o10475761,
[code]...
finally add a HINT /*+ gather_plan_statistics push_pred(TABLE) */ and the result was not very good in this case, but improved the resolution of the view, the rest got worse
SQL Statement from editor:
SELECT /*+ gather_plan_statistics push_pred(o10475761) */ COUNT(o10475761.SUC_ID)
FROM GAR_DW.ARTICULOS o10475528,
GAR_DW.EMPRESAS o10475602,

SQL & PL/SQL :: Is It Better To Use UNION (or) UNION ALL With DISTINCT
Apr 22, 2010Is it better to use UNION (or) UNION ALL with DISTINCT,Which one will improve performance.
Query1:
SELECT deptno FROM emp

Query2:
SELECT DISTINCT * FROM(SELECT deptno FROM emp

I mean to say query1 is better (or) query2 is better,which query improves the performance.
SQL & PL/SQL :: Alternative For Not In
Nov 8, 2011I've got to create 2 tables...
Table 1 include members of a certain club with specific criteria
Table 2 needs to include everyone else on the main database, not in the club, but with the same criteria.
So, ultimate goal is to have two tables, similar criteria, T1 = club members and T2 = non-club members
Table 1 ran just fine.
Table 2 is running and running and running. I'm looking for a more efficient way then the syntax below:
create table NON_club_Members nologging as
select distinct hcp.ID, count (distinct hcp.profile_key)
from mrtcustomer.table_1 hcp, Club_Members cm
where hcp.child_birth_dt between '31-OCT-2000' and '30-OCT-2011'
and hcp.ID not in
(select cm.id from Club_Members)
group by hcp.id
I've also tried <> and that also ran and ran and ran.

Jan 12, 2011I have been told that I cannot use Oracle directory objects, external tables and the UTL_FILE package in my production environment for security reasons.
In this scenario what are the alternate options available in Oracle to write a file and save it in a specific location in the server. One of my requirement is to process a file and write the results of processing in a output file in the application server which in turn will be accessed by the online application.
Alternative To DESC
Dec 12, 2006For whatever reason, in PHP, DESC statements do not work. They're simply unrecognized and you get an OCI "invalid SQL statement" error. It may be some sort of security feature. I've also had the same result with the SQL scratchpad in the Java EM, but not in SQL Plus. Is there an alternative method for getting details on a table that I can use that also doesn't require being logged in as a SYSDBA?

Client Tools :: SQL Monitor Alternative?
Jan 5, 2011Many moons ago, at a previous employer, I had access to the SQL Monitor tool that came with TOAD. I could really use an alternative to this now, as we don't have TOAD here, and it would need to be free. I'm getting a problem with a forms update failing, and I really need to see what's actually being submitted to the database by the form. We're still stuck on Forms 6 by the way

PL/SQL :: Getting Alternative To LEFT OUTER JOIN?

Performance Tuning :: Getting Alternative To REPLACE Function?
Jun 12, 2010I have a table with:
1 million rows
average row length 200 bytes
50 columns
and this update statement
UPDATE mytable SET varchar2_4000_column = replace(replace(replace...300 times)
It looks at every row in the table (no WHERE clause) and does these 300 replace operations on this column for each row. Each replace replaces with a null so effectively it is removing strings. Much of the time these strings are not in the column.
This update statement takes 25 minutes and it is 98% CPU and 2% USER_IO time.
I figure that is what is taking all the time since it is a CPU bound statement. if rows in this table are persistent over time then tag rows with a flag to show which ones have already been processed and skip these next time around.

SQL & PL/SQL :: Alternative To Nested Group By For Performance Enhancement?
Dec 1, 2011I need consultation on an alternative to a query that I wrote and seems very expensive.
I have the following table:
CREATE TABLE TRY_B
(TID NUMBER PRIMARY KEY,
INFO1 VARCHAR2(10),
INFO2 VARCHAR2(10),
GROUP_NO NUMBER,
TYPEID NUMBER);
[code]....
My objective is to get the data of group_no that is repeated more than once and which includes exactly one occurrence of typeid = 0.
My current query is:
SELECT * FROM TRY_B
WHERE GROUP_NO IN
(
SELECT GROUP_NO
FROM TRY_B
GROUP BY GROUP_NO
[code]....
which works but takes very long time with the real data as my real table is huge.

Application Express :: How To Know Which Default Alternative Report Selected
Oct 15, 2012I'm using apex 4.1 and create a page with Interactive report with one default primary report and several default alternative report. when i selected one alternative report, how do i know which one is i picked up? it looks obvious to the user but my point is when the user switches to another page, or there are something should change based on the selected report, i want the user see the new page with-in the context of what have selected for that IR report. for example, i have a "summary" report based on year, so the alternative report will be year-2011, year-2012, etc, when user selected this year, 2012, on the same IR page, there is another report based on year 2012, when user selected 2011, that report should show 2011 report.
View 0 Replies View RelatedReplication :: Alternative For Complete Refresh / Delete Records From MVIEWS?
Aug 19, 2009TABLE NAME :ABC
(PARTITION BASE TABLE - 84 Partition and each Partition has 500-800 Millions of Records)
/* Step1 Create MATERIALIZED VIEW LOG */
CREATE MATERIALIZED VIEW LOG ON ABC;
/* Step2 Create MATERIALIZED VIEW Refresh after Every 20 Minutes */
CREATE MATERIALIZED VIEW MV_ABC
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE+20/ (24*60) AS
SELECT * FROM ABC
WHERE TMSTP > SYSDATE-1;
Scenario:Intially data extracted will be "Greater than SYSDATE-1 = 18/08/2009 11:27:39 " - 76 Millions of Records After 20 Min of FAST Refresh, it will add 2500 Records
i)Is query in the MVIEWS (MV_ABC) SYSDATE-1 will be changed on each FAST Refresh, as observation (as per definition) it is incrementing the records to intial extracted data?
ii)As COMPLETE Refresh will be expensive to execute on the partition base table on each refresh.
Is there any alternative way to achieve the Nature of COMPLETE REFRESH in Materialized View?
iii)Is Delete or Conditional Delete option is possible in Materialized View (i.e not a delete from the base table but the delete from MVIEWS)?
iv)What is the machnism for populating the logs for MVIEWS?Is it overhead for the system and better than a Trigger based approach?

SQL & PL/SQL :: Query Without Using A UNION?
Aug 17, 2011I'm just trying to see if there is another way of doing this query without using a UNION. The only way I can see is using a UNION but maybe I'm missing something or a way to do it without a UNION.
Result:
Select any customer within the user_states table who lives in "MO"
Select any customer within the user_cars table who lives in "MO" and has a "White" car
Select any customer within the user_plates table who lives in "MO" and has a plate of "A" or "B"
Join to the user_names table to display the customers name
So, the result would be any customer who lives in "MO" who owns a "White" car and any customer who lives in "MO" who has a plate of "A" or "B".
SQL
select b.customer_id,
b.first_name,
b.last_name
