SQL & PL/SQL :: Update New Records - Arithmetic Calculations On Some Variables
Jun 17, 2013
I have a table which is updated with new records in each 15minutes from network. In order to get the accurate information I must do some arithmetic calculations on some variables.
For example, if the value for column A is 10 @9.45AM and 15 for @10AM the real result should be 15-10=5 for 10AM; because the values are cumulative so I need to subtract. Similar to this I have same operations for 9 more attributes in my table as well.
In order to handle this I used view and did necessary operations by using joining table like this (table name is Operations lets say and id is Primary Key)
create view ....
...
from Operations current, Operations prev
where current.datetime(+) = prev.datetime - 1 / 96
and current.id = prev.id
When I use this view, the simple select query takes about 15min since I have 25GB record for this table. What can I use instead of this join and solve cumulative values issue?
I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE: CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT ( CALENDAR_KEY INTEGER NOT NULL, DAY_TIME_KEY INTEGER NOT NULL, SITE_KEY NUMBER NOT NULL, RESERVATION_AGENT_KEY INTEGER NOT NULL, LOSS_CODE VARCHAR2(30) NOT NULL, PROP_ID VARCHAR2(5) NOT NULL, [code].....
I am fairly new to Oracle SQL developer and I am having an issue that may very simple but I just cannot work it out logically for some reason.I am trying to calculate the percentage of sales each employee has made form the total of trades. I have been trying to use the COUNT function but it obviously splits the counts for each employee. I then tried a inline view but couldn't get it to work and also a sub-query and had an issue with "not a single group function" and then "not a GROUP BY expression".
how I can do this? I will also need to add the syntax to another inline view
The biggest problem at the moment I have is that I don't know how to go trough all record set having to read it in only once. And other is my calculations doesn't work and im not really sure why.
Does Oracle have a package that can handle 'big number' (bignum) arithmetic, that is, decimal digits of 300 to 1000 characters in length, or more? I know 'binary_double' can handle E+308 but that is with precision.
A project here is looking at using prime numbers and we need to store the result of multiplying up to the first 950 or so prime numbers.
Version of the database you are using: Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production Version of Application Express: 4.1.1.00.23
I have a requirement that is driving me stark raving bonkers.
I have a form that a user fills out, it sets the Status to 'Open' and I capture the Date Created On in a hidden field. When someone goes back in to the Form and sets the Status to 'Closed' I capture the Date Closed On in a hidden field. I need to calculate how many hours that it took to close the issue and display it on the form.
I am running APEX 4.0.2.I am having an issue where I have a page item that has a post calculation
My source used is "Always..." My source type is "Database Column"
I have tried putting the code in the page item under "Post Calculation Computation", as a dynamic action, and as a Computation Process. It displays properly on the form no matter where I put the code, but when I select Apply Changes it is not updating the database. What am I doing wrong? I have provided a sample of the code, and yes the column name is in the database.
CASE WHEN :P12_NUM_OF_BOOKED_DEALS>0 AND :P12_DATE_1ST_COMPLETE IS NULL THEN '(2) In Process' ELSE '(D1) Open Draft' END
Which of the below is considered a bind variable. In example one proc. Test the parameter p1 is directly used in the query, so this can be considered as a bind variable.
Is that true about the second proc. where p1 is assigned to a local variable v1 , or this needs hard parsing because v1 is not a bind variable ?
Create or replace procedure test(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS BEGIN OPEN p_refcursor FOR select * from Test_tab WHERE item=p1; END; ------------ Create or replace procedure test1(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS v1 varchar2(100):=p1; BEGIN OPEN p_refcursor FOR select * from Test_tab WHERE item=v1; END;
I should get values as 0, -34 and 77. But I don't get this as all operations with null gives null. These are fetched data and don't exist in the form shown. I have to use these row values of "Change" further. Is there any way of obtaining these results?
and I want to insert First Name and Second Name records using the ID as the reference. The new data is currently in a .csv file, but I could put them in another table if that's easier.
ID|First Name|Second Name 1|Adam|Adamson 2|Ben|Benson 3|Chris|Christophers 4|Dave|Davidson
I understand how to do individual updates, I want to know how it is possible for me to do this as one query, as I have several thousand records to update.
I want to update a table 8 million records of a table which has 10 millions records, what could be the best strategy if the table has a BLOB column with 600GB worth of data. BLOB itself is 550GB. I am not updating the BLOB column. Usually with non-BLOB data i have tried doing "CREATE TABLE new_table as select <do the update "here"> from old_table;" method .
Now i want to UPDATE reducing the AVAILABLE column by 1 in COURSESEATS table based on common columns collegecode,coursecode for a ROW inserted into SEATALLOTMENT table ,i am confused to what approach i have to follow whether its a procedure or a trigger
CASE:
Here in this case as i insert a row with krcl,cse as college code and course code respectively into seatallotment table the available column in courseseat table for the respective row with mentioned common column must become 59 from 60
I need to update more than 1million records in a table. I am using Oracle Warehouse Builder to do this Job. it is taking more than 3 hours still running. I don't have any Indexes on this table.
The requirement is I have a table (TAB1), wherein I have 3 columns, ID, LID and STATUS.
The value in ID column = ID_SEQ.NEXTVAL,and LID will be either 0 or 1 and the possible values for STATUS are 'ED','CP', NULL. The ID column is not suppose to have duplicate values, but there is no check on the table for the same.
Someone has updated the existing data and ID column is containing duplicate values. Wherever LID = 0 and STATUS = NULL and if only if ID is duplicated then the ID_SEQ.NEXTVAL has to be assigned to ID field, so that there are no more duplicate values.
CREATE TABLE tab1 (id NUMBER , lid NUMBER, status VARCHAR2(10));
Existing Data ------------------ INSERT INTO tab1 VALUES (1,0, 'ED'); INSERT INTO tab1 VALUES (1,0, 'CP'); INSERT INTO tab1 VALUES (1,0, NULL); INSERT INTO tab1 VALUES (1,0, NULL); INSERT INTO tab1 VALUES (1,0, NULL); INSERT INTO tab1 VALUES (1,0, NULL);
i have a table in my PD database which have more than 30,000 records .some records in a column say p_code is not tagged with code like '9876543'while other records are tagged in this column with code such as '19022345678'.
Now i want to update these records with tagging 1902 with each one .
Lets take the basic emp table for our Referenece and lets assume that it contains around 60000 Records and all the deptno in that table are Initially 10. Please provide an update statement which would update deptno column of EMP table((based on) order by EMPNO) in for every 120 records incrementing by 1.(DeptNo to be incremented by 1,like 10 ,11 , 12 etc).
First 120 Records deptno should be 10, Next 120 Records deptno should be 11, and so on. . . . . . . For Last 120 records deptno should be updated with 500.
want to update 230 records in ins_spr table but its returning error..

My table have duplicate records. I want to impose a primary key on that table. For that I have to replace duplicate values of a column with next value of a sequence.
i am trying to update multiple records using store procedure but failed to achieve
for example my source is
emp_name sal abhi 2000 arti 1500 priya 1700
i want to increase salary of emp whose salary is less than 2000 it means rest two salary should get update..using stored procedure only
i have tried following code
create or replace procedure upt_sal(p_sal out emp.sal%type, p_cursor out sys_refcursor) is begin open p_cursor for select sal into p_sal from emp; if sal<2000 then update emp set sal= sal+200; end i;f end;
and i have called the procedure using following codes
set serveroutput on declare p_sal emp.sal%type; v_cursor sys_refcursor; begin upt_sal(p_sal,v_cursor); fetch v_cursor into p_sal; dbms_output.put_line(p_sal); end;
the program is executing but i should get o/p like this after updating
I want to update / insert records from one user to other user therefore I write this code in my form but it gives me error.
REPORT_DETAILS is a detail table of REPORT_PARAM, given code is working fine at master tables.
Form always goes in TOO_MANY_ROWS exception.
Correct my code, my requirement is: if data found then update else insert new record.
declare cursor c1 is select * from factory_data.report_details order by rd_rp_id; rec c1%rowtype; v_check varchar2(1) := null; begin for rec in c1 loop [code].......
