I need to get data from a table in which dates is equal from previous month. The dates in this table has a formula DD-MMM-YY (CRE_DTTM is the name for date column).
I've already achieve getting data from the previous month by using this formula:
My problem now is what if the current month is for example JAN 2011.. I need to get the data from DEC 2010. How can I query the previous year in this case?
Using 11gR2, windows 7 client machine. I need to update the table missing_volume (below), where I need to calculate the estimated_missing column. The calculation of estimated_missing column for current month needs previous month numbers (as commented inside the code below). I want the output like the first table. Notice the records start from January, hence estimated_missing for January can't be calculated, but for the the rest of the months it can be done by simply changing 'yr' and 'mnth' (commented inside the code towards the end).
yr mnth location volume actual_missing expected_missing estimated_missing --------------------------------------------------------------------------------------------------------------------------------- 2013 January loc1 48037 24 57 2013 February loc1 47960 3660 53 24 2013 March loc1 55007 78 57 28 2013 April loc1 54345 72 58 77The code:
UPDATE missing_volume g
[Code]....
The code does calculate correct number for 'estimated_missing' as I run the code for each month, but the problem is while updating the current month it also erases the record for previous month. E.g. as can be seen below, after I updated April the column only has the record for April, previous month record is gone, similarly updating March removed February, etc. I can't understand why it's happening!! Here is the output I get:
yr mnth location volume actual_missing expected_missing estimated_missing --------------------------------------------------------------------------------------------------------------------------------- 2013 January loc1 48037 24 57 2013 February loc1 47960 3660 53 2013 March loc1 55007 78 57 2013 April loc1 54345 72 58 77
why it's happening (I mean where is the flaw in the code) and how to get the desired output (first table).
I have a requirement to list the data month wise dynamically where month data is also in the same table, hopefully the below posts should bring more clarity to my requirements.
when i press when button pressed trigger, i want first the form will delete all the previous data and then populate the data from the table, that's why i used clear_block first, but this clear_code is not working here. my coding is given below
go_block('show'); clear_block(NO_VALIDATE); declare cursor c1 is select * from qtr_demand order by 1; begin [code]..........
I would like to have a query which should fetch previous day records from column which is having timestamp data type.
select mdn from user_table where updatetimestamp > trunc(sysdate) - INTErVAL '24' HOUR;
But this gives output not for previous day, but all records which are 24 hrs less than current day. How to get records for previous day based on column having timestamp data type.
We want to find out difference of data for some tables between current day & previous day. We can use query with minus operation but it will take lot of time since table size is in range from 200 to 500 GB. We have to do this exercise every day.
Got Active DataGuard on a primary database, quite nicely sending its archive logs to its secondary. I can quite happily use the Broker and switchover between them.
Now if I take RMAN backups of the primary database, if I have to failover to the secondary, I'm gonna loose all those backups.
Well, I can restore the whole database to the backup, cos I can restore the control file, from the backuip and therefore I can restore the whole db.
But if I want to restore to a tablespace, I wont be able to , cos the db_unique_names names are different, and the DB ID's will be different.
Same goes if I use a recovery catalog....
so how do I failover/switchover without loosing my previous rman backups ??
I've got values for each workday of month in table. Chief said we don't load values of weekend because of space and time economy. Weekend value is copy of last workday. How do I count average for month in this case? Technical task in Excel worksheet consist of each day of month, so average value is 14 689 262,86. I should get the same result in my query. My example below shows values, 0 is workday (present in table), 1 is weekend (absent in table)..
select 12230427, 0 from dual union all select 11960157, 0 from dual union all select 12965902, 0 from dual union all select 13939736, 0 from dual
I have an requirement to load past and future data from different source table to one tgt table.Say now we are in July
Past Data Apr May Jun
Future Data Aug Sep Oct
I HAVE actual sales for past month and present month which is in Table A & expected sales in table B.for every month i have to load 7 months data TARGRT TABLE..
In future the requirement may change to 6 months also. in that case the procedure has to load past 6 month + current month + 6month future so totally 13 month should be loaded.
I need for each date sum the values from the begin of the year to present date. In January I will have the value of this month, on February I must sum the value of this month and the value of the month before, and so on, at the end of the year.
Date input

How to get the previous value of row with calling function to add value in SELECT statement for the row value.
Consider the example Table A1 having column a with values 1,NULL,NULL,NULL
SELECT CASE WHEN a IS NULL THEN (prev_row_value+function_return_Value) ELSE a END as A from A1
And my result-set should be like
a ---------------------- 1 1+(Return Value Of Function) Prev_Row_Value+(Return Value Of Function) Prev_Row_Value+(Return Value Of Function) Below is sample code but doesn't fulfill my criteria
We have employee salary table which will have salary of an employee on daily basis (only working days). Below is the table structure:
CODEemp_salary ---------- emp_id NUMBER(15) NOT NULL effective_date DATE NOT NULL salary NUMBER(15) NOT NULL
Primary key - emp_id, effective_date..This table is yearly partitioned...I have to find out how long the salary is not changed for an employee from given date, and last salary. I am using below query to do this:
CODEWITH salary_tab AS (SELECT effective_date, salary, (CASE WHEN (LAG (salary) OVER (PARTITION BY emp_id ORDER BY effective_date ASC) = salary
[code]....
For emp_id 1, if we ran this query for 10/31/2011, then it has to compare the 10/31 salary with 10/29 and do the same until the salary mismatches. In this case, salary salary mismatch occurs on 10/20, so the stale salary period is from 10/31 to 10/21 which is 7 days.Below query will give that result:
CODE WITH salary_tab AS (SELECT effective_date, salary, (CASE WHEN (LAG (salary) OVER (PARTITION BY emp_id ORDER BY effective_date ASC) = salary
I take a select into a cursor and process it record by record.I have to do sum based on a column and display row by row by using dbms_output.put_line .... So the sum has to happen based on a column. Based on the column value i need to display the cumulative sum as well.
Example:-
col1 col2 amount DL AADD 25 DL BBCC 10 DL BBRR 15
Sum value for DL ----- 50
TX ADED 20 TX EDWW 60
Sum value for TX ----- 80
All the above data should be displayed using DBMS_OUTPUT.PUT_LINE in a pl/sql code. I use cursor to take the values from the table but the problem i face is .... I am not able to display the sum based in the col1 values.
Since i use the cursor .. i took the col1 values in to a variable and checked every time old_variable = new_variable if yes then continue the sum else display the sum value.
once i get the above check satisfied i am loosing a new col1 row in the check. The next loop only run for the new col1 values -1( which is used in the check loop).So is there any better way to get the solution or is there a facility to store the previous loop values in a cursor ? so that i dont have to loose that one row of data.
I am not able to come up with proper loop so which can identify that the col1 has changed and you have to display the sum value.
How to achieve "Prev_Value" column as shown below without using ORACLE analytic functions
I have records stored in table for various categories and based on ID / Name / Office / Product / Category combination I want to achieve previous value column through efficient SQL query
Instead of me entering the date any way to take the previous day till mid-night.
I dont think sysdate-1 will work for me because if I enter sysdate-1 it will take from now -1 that means 18-mar-13 15.45.45 but I want till the previous date until mid-night.
I am trying to set the min date if there is no gap between dates.compare previous date2 value with current date1,if they are same then my new date will be min(date1).
I'm making a menu in my form, wherein it has FILE, TRANSACTION and REPORT. Under FILE it has BACK, and LOGOUT. In my back menu item, i want to go back to the previous block or previous module. I used previous_block but it's not working in some of my blocks.
