PL/SQL :: Get Previous Sunday Through Saturday From Each Sunday
Sep 10, 2012
I need to get the previous Sunday through Saturday from each Sunday. I want to run the report every Sunday and it will compare the previous dates from Sunday to Saturday.
here I need to exclude the Dates which comes on 'saturday' and 'sunday' and also the common holiday..Here it is '01-May-2012' and I need the output like the following,
i need to write a function to eliminate SUNDAY AND SATURDAY;
My criteria is
if My date as (5/19/2012 ) and i want to add 10 days to it themn my function should return 06/01/2012 if My date as (5/13/2012 ) and i want to add 12 days to it themn my function should return 05/29/2012
I given the table name,column name,datatype and sample record in the table. I have given the sample record for 01-jan-2008 to 8-Jan-2008, but in the real thing it will be for 30 years.
My Requirement:
For each class_no (202,203..), I need the missing date excluding weekends (sat, sun), I have provided the sample output below.
Table Name : ABC
Column Name : Class_no Data Type : Number Column Name : Class_DateData Type : Date
1. Year's first week starts with first Sunday of the year. (6th Jan 2013 will be the starting week (week 1) in Year 2013) 2. 2nd Jan 2013 will be the last week of the previous year i.e. 2012 (either 52th or 53rd week)
At many place I found the below solution:
select to_char(to_date('01-JAN-2008','DD-MON-YYYY')+1,'IW') week_number from dual;
But its not working for the given dates (2nd Jan 2013, which should fall in the last week of 2012, and 6th Jan 2013, which should be the starting week of 2013).
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
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?
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.
I have a stat table that got info like login_date,user_id etc.For a specific user, i have a requirement based on the no of days difference between the current login date and last login date.
For example, Tom logged in on June 4th 2013. His previous login was May 31. So no_of_days_difference is 5 days.How to programmatically get this for each user inside a pl-sql sub block.
