how can i compute row wise multiplication for each unique value of id. I am trying to get the output as showing id and their respective results after multiplying the corresponding values.
CREATE TABLE mult_tbl(
id NUMBER,
val number
);
insert all
into mult_tbl values (1,2)
into mult_tbl values (1,3)
[code]....
I need to multiply the values, which are in as a single column value.
Ex:
select R From awr_hist_model_ror where model_id = 60399 order by start_date
1.01
1.011
1.012
1.013
1.014
1.015
1.016
1.017
1.018
1.019
1.02
1.021
1.022
1.023
1.024
1.025
1.026
1.027
1.028
1.029
i need to multiply below column values.
Using Oracle 11g, below is the table, partitions, unique and non-unique local index:
CREATE TABLE DOCA( DOCA_ID NUMBER NOT NULL , DOCA_BKG_PAX_ID NUMBER NULL , ROW_PURGE_DATE DATE NULL ,)PARTITION BY RANGE(ROW_PURGE_DATE)INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))( PARTITION P2007 VALUES LESS THAN (TO_DATE('01/01/2008', 'dd/mm/yyyy')), PARTITION P200801 VALUES LESS THAN (TO_DATE('01/02/2008', 'dd/mm/yyyy')),) TABLESPACE T0; ALTER TABLE DOCA ENABLE ROW MOVEMENT;
CREATE UNIQUE INDEX XPKDOCA ON DOCA( DOCA_ID ASC, ROW_PURGE_DATE ASC)LOCALREVERSE TABLESPACE I0; ALTER TABLE DOCA ADD CONSTRAINT XPKDOCA PRIMARY KEY (DOCA_ID); CREATE INDEX XFKDOCA_DOCA_BKG_PAX_ID ON DOCA( DOCA_BKG_PAX_ID ASC)LOCALREVERSETABLESPACE I0;
I would like to know the difference between the performance of the unique and non-unique local indexes?.
1) Why we need to do Compute Statistic on index.
2) Is it only for optimizer to make a better plan?
3) If yes, which means, optimizer will not able to collect statistic by itself?
4) if I'm not collect statistic, then optimizer will do it or skip.
I'm a student researching SQL, Oracle queries. I'm currently writing a oracle:JDBC to query by id, then receive all tuples that belong to id and compute GPA. I convert letter-grade to # in query how to count rows pertaining to id, then average GPA of all tuples. I understand Count(*) where sid=?, but i need to count the rows for id, then convert letter to number, finally compute gpa for all pertaining tuples belonging to id.
Everything works find but the last query for my JDBC prog.Here is my query as of now...
"SELECT grade, CASE WHEN grade = 'F' THEN 0 WHEN grade = 'D' THEN 1 WHEN grade = 'C' THEN 2 WHEN grade = 'B' THEN 3 WHEN grade= 'A' THEN 4 END AS letter_grade FROM Grades"
How do I count all tuples then compute the gpa pertaining to id.For all IDs?
I have to create some indexes in a production database. Do I need to Compute Statistics after creating indexes? Or when I create they automatically are computed?
The version I'm using is:
Oracle Database 10g Release 10.2.0.5.0 - 64bit Production
PL/SQL Release 10.2.0.5.0 - Production

My issue is with a calculation using columns as variables. below is the code to create and attached is the code (INSERT_data.txt) to fill-in the required tables....
what's required here?
I need to update (through update or simply create new table statement)
BPF(i), BPC(i), BPY(i) of table root_tbl (A) based on InF_IDX, InC_IDX & InY_IDX and OutF_IDX, OutC_IDX & OutY_IDX using BPF(i), BPC(i), BPY(i) from table pvt_vectors_tbl(B).
Join Clause: A.P_NODE=B..P_NODE and
A.C_NODE=B.C_NODE and
A.P_NODE_Date=B.P_NODE_Date and
A.C_NODE_Date=B.C_NODE_Date
the formula are:
BPF(i):
if A.InF_IDX<=A.OutF_IDX then
FOR i=1 to A.OutF_IDX+1
if i<InF_IDX then A.BPF(i)= A.BPF(i)+ B.BPF(OutF_IDX + i - InF_IDX); else A.BPF(i)=0;
i=i+1;
else
FOR i=1 to A.InF_IDX+1
if i<OutF_IDX then A.BPF(i)= A.BPF(i)+ B.BPF(InF_IDX + i - OutF_IDX); else A.BPF(i)=0;
i=i+1;
idem for BPc and BPY.
in real word:
* root_tbl table has ~2 million records, 50 BPF(i) columns, 50 BPC(i) columns and ~475 BPY(i) columns
* pvt_vectors_tbl has ~50.000 records
/*create and fill-in pvt_vectors_tbl table*/
CREATE TABLE root_tbl
(
P_NODE VARCHAR2(3),
C_NODE VARCHAR2(3),
P_NODE_Date date,
C_NODE_Date date,
InF_IDX number,
InC_IDX number,
InY_IDX number,

I am new to PL/SQL and how to create a trigger to compute the population of the school from the groups of students and store back in population. It also needs to check that there is a min of 10 students to a school.

i have a Field item on my report which i would like to show "Price INCL of VAT". Any PL/SQL code or trigger to do this? VAT is 16%
I'm a Forms programmer, not so familiar with Reports.I suspect, it should be something like this:
F_1 := F_1 * 1.16
the problem below:
I have a table AlertData below:
DeptIDMONTHCount
192010-041392
192010-051134
192010-061094
192010-071333
292010-042217
[Code]...
Within each DeptID group I need to calculate absolute change of 'Count' column between previous and current months and compare change value with threshold.
If ratio >= threshold N number of times I need to make a note of that event. Threshold = 0.1 N = 2 - alert needs to exceed threshold two consequtive times
Here is data processing algorithm:
1. Calculate change between month 2010-04 and 2010-05: abs((1134/1392 - 1))= 0.18;
2. check change value against threshold: 0.18 > 0.1
3. Threshold was exceeded, set alert_fired_cnt counter to = 1
4. Once alert fired it creates a baseline for comparison - I need to use Count from month 2010-04: We're now in month 2010-06: abs(1094 / 1392 - 1)=0.21
5. check change value against threshold: 0.21 > 0.1
6. Threshold was exceeded, increment alert_fired_cnt counter by 1 = 2
7. At this point alert exceede threshold two times, I need to set a alert_triggered flag = 1 and reset alert_fired_cnt = 0 for further calculations
8. We're in montn 2010-07: abs(1333/1294-1)=0.03
8. check change value against threshold: 0.03 < 0.1
9. Since threshold was not exceeded, keep alert_fired_cnt counter to = 0
Above algorithm needs to be run for all DeptID groups.
I load above data into an associative array and loop through elements. I am having trouble keeping computations within each DeptID group.
I have an interactive report with two columns timestamp type. I want to use the compute action in order to get the difference between those dates. Nevertheless I got values like this: +000000008 00:00:00.000000.

I tried BRK and COMPUTE commands myself after reading the documentation but its not working...The output of my script is correct but What I want is the information to be displayed on a different way:
Original script for the report:
set serveroutput on size 1000000
set pages 10000
set lines 1000
set arraysize 1
set trimspool on
set heading off
[code]....
The output should be exactly as above as the requirement is this should be in this particular order and how many is the count in each thoroughfare or locality, as shown in the final output, above.
I load a table through sql loader which takes nearly 14 min for 8-9 millions records, once the records complete i run the analyze table compute statics to gather stats and it takes nearly 15 min. is there any ways so that i can reduce the stats timing. the stats collection command runs from other schema not from where the table is residing.

like this for all 12 months at a single query.
I have a table which have three column.

For one of our requirement, we are asked to provided data in below manner.
Deptno Deptname emp_name_1 hire_date_1 emp_name_2 hire_date_2
10 Sales Raghu 25-Jan-2007 Abbhilash 29-Mar-2009
If a particular department has 10 employees it should have data upto emp_name_10,if department has only 5 employess it should data upto emp_name_5 and so on.I came up with below approach, in this approach I need to create new table to store the data in row wise.
In my actual requirement 4 tables needs to be joined and 2 of the tables are very large.Is there any other approach without creating a new table, something within pl/sql.
drop table emp_dept;
create table emp_dept(deptno number,dept_name varchar2(100),emp_name varchar2(100),hire_date date,seq_cnt number,total_cnt number);
insert into emp_dept
[code]...
I want output like given below. Using EMp table . if sal is <1000 means count of Emp's who are having lessthan 1000 like that.
Deptno sal sal sal sal
<=1000 <=2000 <=3000 <= 5000

Web page that retrives data from SQL database and display it to the user in well formatted manner. Data retrieved depend upon criterias selected by the user. But sometimes data retrieved is very large. I want to display records to the user page wise, i.e. 100 records on first page and next 100 records displayed when user clicks next button. This means only 100 records should be retrieved when user first select search criteria, next 100 records retrived when he clicks next button and so on, as to reduce data transferred from server to client. how to achieve this by using single sql query as soon as possible.
