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
insert into a values(1,3,'Y',5); insert into a values(2,2,'Y',4); insert into a values(3,3,'N',3); insert into a values(4,4,'Y',3); insert into a values(5,1,'N',6); insert into a values(6,2,'N',5); insert into a values(7,2,'Y',4); insert into a values(8,3,'N',2); insert into a values(9,4,'Y',2); insert into a values(10,1,'Y',3); . SQL>select * from v$version; Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
My logic should have the output as follows without 5th column: sourcerowleveldpnqtyremark13Y522Y4This row in main table shouldn't be displayed in the query result as it has
dpn='N'44Y3*3=9In this row qty=9 will bedisplayed.
It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.this row will not be displayed as dpn='N'this row will not be displayed as dpn='N'72Y4*6=24in its previous row level value is same so it will check the previous to previous row where level is 1(parent of current row) and dpn='N' ,then it will multiply the qty of that row with current row and display the value in qty column.this row will not be displayed as dpn='N'94Y2*2=4In this row qty=4 will be displayed.It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.101Y3It will not check for the previous rows as level 1 doesn't have any parent.
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?
I could execute a package for eg if i had a package with procedures related to statistics and i run them each night, could i just do an exec on the package and it would run all those procedures??
Its not possible but i could call each procedure from ONE procedure
I am getting errors while executing the following block.
create TYPE c_Rec as object(a VARCHAR2(1), b NUMBER); DECLARE -- TYPE c_Rec as object(a VARCHAR2(1), b NUMBER); TYPE c_collection IS TABLE OF c_Rec; l_coll c_collection := c_collection(); BEGIN [code]........

how to use the MERGE Statement. actually I've used oracle Merge Statement before and it works very well. However today I tried to use and perform a command like that:
Merge into myTable mt using ( select 'data' field1, 'data2' field2, ect from dual union select 'data' field1, 'data2' field2, ect from dual union
[code]...
This has not worked.What am I doing wrong?What could I do to solve this problem and axecute this statement sucessfully?
I'm trying to execute a procedure within a Declare/Begin/End statement and using variables as input parameters in my procedure but I keep on getting an Invalid SQL Statement Error. My code is below:
declare
START_dt VARCHAR2(30); END_DT VARCHAR2(30);
begin
SELECT '01-APR-2011' INTO END_DT FROM DUAL; [code]....
The table the procedure is pulling data from doesn't have proper date/time stamps but my procedure takes the varchar dates above and turns them into dates in the procedure so the input date parameters are left as just string characters.
there are 4 jobs scheduled in oracle dbms_job. 3 jobs will run everyday at 4.00AM. 1 job will run at every hour.Daily jobs are running fine. But hourly job is not executing automatically. If forced (exec dbms_job.run(<enter here job number>), this execute fine.
job_queue_processes=5 total jobs in schema=2503 total jobs in db = 2614
Even there are many jobs scheduled, next_date for 2234 jobs are lesser than the sysdate. Again in 269(2503-2234) jobs, 2265 are having NULL in the interval column.
Database 2(sm02): ============= oracle, 9.2.0.6
there are 4 jobs scheduled in oracle dbms_job. 3 jobs will run everyday at 4.00AM. 1 job will run at every hour.All the jobs are not running automatically. If forced (exec dbms_job.run(<enter here job number>), these execute fine.
job_queue_processes=5 total jobs in schema=7 total jobs in db = 7
I planning to follow the below steps to avoid the above issue.
1.) Restart the job queue process by executing alter system set job_queue_processes=0
2.) Increase the value for the job_queue_processes.
3.) Restart the database
But I got stuck in the 2nd step. what value I need to put for this job_queue_processes parameter?
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.
