SQL & PL/SQL :: Query Gets Slower By Adding Order By Clause
Apr 14, 2010I have a query, running the query with order by and without orderby clasue casues big performance difference.
here without order by it takes 5 sec
.
SELECT
audit_number,

PL/SQL :: Adding Columns To Count Contents Of Other?
Aug 31, 2013how to incorporate counts into my current SQL code that would count food items, and then car items for each person. Once I understand this concept I hope to apply it to my real database (in Oracle) where I am counting medications and problems for each patient.For example using my test data below, the my goal would be to have count columns show that Cathy had 3 food count and a 1 cars item (the count would need to ignore the null values in these columns). I don't really care if the count value repeats in every row for that person.
Select data1.Name, data1.Category,Data1.Results,Case When data1.Category IN ('food') then data1.results end FOOD,Case When data1.Category IN ('Cars')then data1.Results end CARSFROM(Select T1.name Name, null Category, null Results from a_Main T1, a_Food T2 Where T1.cpi_seq = T2.CPI_SEQUNION Select T1.name, 'food', T2.Food from a_Main T1, a_Food T2 Where T1.cpi_seq = T2.CPI_SEQUNIONSelect T1.name, 'cars', T3.Cars from a_Main T1, a_Cars T3 Where T1.cpi_seq = T3.CPI_SEQ)data1where data1.Category is not nullorder by Name,

Performance Tuning :: Order Of Steps In Execution Path And Order Of Predicates In The Plan
Mar 20, 2012Which step in the following plan is the first step of execution
I reckon it is "TABLE ACCESS BY INDEX ROWID| BANK_BATCH_STATE"
Is that correct?
In the "Predicate Information (identified by operation id):"
section the predicates - access and filter for the step "TABLE ACCESS FULL | PYMNT_DUES" are displayed first
Isn't there any relation between the order of execution steps and the order in which predicates are displayed?

SQL & PL/SQL :: Result Order In 2 Table Joins Without Order By
Sep 6, 2011I have below tables,
describe rpthead
Name Null Type
--------------------------- -------- -------------
RPTNO NOT NULL NUMBER
RPTDATE NOT NULL DATE
RPTD_BY NOT NULL VARCHAR2(25)
PRODUCT_ID NOT NULL NUMBER
describe rptbody
Name Null Type
------------- -------- -------------
RPTNO NOT NULL NUMBER
LINENO NOT NULL NUMBER
COMMENTS VARCHAR2(240)
UPD_DATE DATE
The fact is that we store some header in RPTHEAD and store real data in RPTBODY, the question is that if I use below SQL to query all data for a 'PRODUCT_ID'.
SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE
FROM RPTBODY t0 , RPTHEAD rpthead
WHERE
(
t0.RPTNO = rpthead.RPTNO
AND
t0.UPD_DATE>=to_date('1970/01/01 00:00:00','YYYY/MM/DD hh24:mi:ss')
AND
rpthead.PRODUCT_ID IN ('4647')
)
I do not want to have 'ORDER by' clause since data set is too large, the sorting takes long time, is there any way to get the result rows in the order sorted by RPTNO? We have the index for RPTNO on RPTBODY.

SQL & PL/SQL :: Adding High And Low To Zip Plus Four Values?
Jan 19, 2011I have a table with zip codes and their plus four values. For ex: zip code of 10000, which has corresponding plus four values of 001, 002, 003, and 008, 009, 010. The issue is just that--a zip code can have sequential plus four values, and then it will skip several potential plus four values, and then start again. I would like to assign a low plus 4 value and high plus four value to a zip code, keeping in mind that the plus four values are not always sequential. So, it would be similar to this:
zip plus4 low plus4 high
10000 001 003
10000 008 010

SQL & PL/SQL :: Adding IF Statement To A Trigger
