SQL & PL/SQL :: Analytical Query To Find First And Last Value In Date?
Jul 2, 2013
My table has two date columns EFF_DT which is the start date and TERM_DT is the end date. The EFF_DT of the next record should be the next date of the TERM_DT record.
In the fourth record, the effective date should be 1-Oct-13 which is the next date to the last TERM_DT 30-Sep-13.As the is the break in the date, the output should show 15-Oct-13 sa the second start date.
Note: Refer to the PI_ID columns, there is a break in the date for the sale PI_ID 'ABC'.
Here I am trying to generate a pseudo column, so that the table with the pseudo column looks like as shown below. and I can use first_value and LAST_value by partitioning on the pseudo column to get the desired output.
1) CNT_VAL is the pseudo column:
-----------------------------
CK_IDPI_IDEFF_DT TERM_DT CNT_VAL
Mem1ABC1-Jan-1331-Mar-131
Mem1ABC1-Apr-1331-May-131
Mem1ABC1-Jun-1330-Sep-131
[code].....
My Query :
----------
I not getting the desired output here as the value in pseudo column is 3.
select CK_ID, PI_ID,EFF_DT,TERM_DT,
(case
when case_CONT - LAG(case_CONT,1) over (ORDER BY EFF_DT) = 0 then to_char(case_CONT)
when case_CONT - LAG(case_CONT,1) over (ORDER BY EFF_DT) <> 0 then to_char(LAG(case_CONT,1) over (ORDER BY EFF_DT) + 1)
else to_char(nvl(case_CONT,0))
building SQL query to get the result as shown below.
Create Table Temp
CREATE TABLE TEMP ( CASEID NUMBER, SATUS VARCHAR2(1 BYTE), TRANS_DATE DATE ) Insert data
[Code]...
I want to build a query which should give output as shown below. Basically i want to select those rows which having minimum trans_date for a given CASEID & Status.
insert into call values(1,9818764535,9899875643,'IN','24-APR-13 02:10:43',10); insert into call values(1,9818764535,9898324234,'IN','24-APR-13 05:06:78',10); insert into call values(1,9818764535,9215468734,'IN','24-APR-13 15:06:78',10); insert into call values(1,9818764535,9899875643,'OUT','25-APR-13 01:06:78',10); insert into call values(1,9899875643,9899875643,,'OUT','25-APR-13 22:06:78',10);
Query : need to find first and last call of '9818764535' mobile number and of call_date between '24-apr-13' and '25-apr-13';
I need to calcaulate the salary avarage for three days prior, leaving the current row. That should happen to every row moving back words.I have given all the details.
create table Employee( ID VARCHAR2(4 BYTE) NOT NULL, name varchar(20), Start_Date DATE, Salary Number(8,2), mv_avg number(8,2) [code]....
We've got a query which returns one row, but uses an IN statement. The IN statement links to more than one row in the subquery. When we use a combination of DISTINCT and an ANALYTICAL sum, the sum total is multiplied by the number of rows in the sub query. Remove the DISTINCT and we get a single value.
A simplified example of the problem is below.
I can't see how a query which returns a single row then returns multiple values with the addition of a DISTINCT. Removing the analytical sum also provides a single row, but we need this in the actual query we're running. So it seems to be some combination of DISTINCT, ANALYTICAL SUM and IN query is causing multiple values to be returned.
CREATE TABLE go_test_distinct1 (gtd_value NUMBER); -- Three identical values -- To replicate the three identical values returned by
I am having a table with 5 lakhs transactions. I want to fetch the last balance for a particular date. So i have have returned a query like below.
SELECT curr_balance FROM transaction_details WHERE acct_num = '10'
[Code]...
This has to be executed for incrementing of 12 months to find the last balance for each particular month. But this query is having more cpu cost, 12 times it is taking huge time. how to remodify athe above query to get the results in faster way using analytical query. Whether this can be broken into two part in PL/SQL to achive the performance. ?
When I run a query form the the Query Window in Visuial Studios 2012 all the date fields truncated to 'mm/dd/yyyy', but i need the full date returned. I am able to get full date from TO_char(MyDateField, 'yyyy-mm-dd hh24:mi:ss'), but if I do TO_DATE(MyDateField, 'yyyy-mm-dd hh24:mi:ss') it only returns 'mm/dd/yyyy'. I'm sure this is a simple setting in Visual studios but I cant find it to save my life. Is there there a way to have the full date returned by default?
I want the query to resolve overlapping dates as well as merge contiguous segment and leave non-contiguous segments as is. The final result of the query should be like this.
I am getting daily basis data from third party in excel format which i am converting into CSV format and then uploading into oracle tables using External tables.Now problem is that every time i getting the dates in diff format i.e. sometimes dd-mon-yyyy , dd/mm/yyyy etc.
Now every time i have to open my code and change it there ...to make it as oracle date format. IS there way i can find out format of date and based on format i can do operations with getting errors every time.
I am storing the TP(Excel date) date into varchar columns only and then varchar2 column value i m inserting/updating into date format using to_Date ().
table_1 contain records on employee and the supervisor they are under at a certain date.
As some employee(00001 & 00003) have a different supervisor from different date, I'll like to extract from table_1 the record of each employee in the table that only contain the supervisor info on the most recent date.And from table_2, i'll like to extract the employee's name. These records extracted from both the tables would the be put into a new table,table_3
Example: For employee 00001, only extract record that have the most recent date which is 04-APRIL-2004 and not on 01-MARCH-2004
I require to find the years between any given date range. For example what are the years between the dates '01/12/2010' and '01/02/2012'? Answer must be '2010,2011,2012'. how to code the query for this result?
The requirement is to find the last date when either ATTRIB1 or ATTRIB2 were modified for each ID. There are many other columns in the table, but I'm not interested in other columns.
Test Case
SET LINES 100 SET PAGES 100 DROP TABLE test_log / CREATE TABLE test_log
[code]....
Expected Output
ID LAST_CHANGE_DATE ---------- -------------------- 11 02-SEP-2012 10:58:32 35 05-AUG-2012 10:58:32
I have written the below query, to get the required output.
SELECT MAX(i_date) last_change_date FROM ( SELECT seq,id, attrib1, attrib2, i_date, row_number() OVER (PARTITION BY attrib1 ORDER BY i_date) rn1, row_number() OVER (PARTITION BY attrib2 ORDER BY i_date) rn2
say for example there is a column called 'date_txn' in a table .When i select that particular column it display output as 'June 2013'.But i want output "with date and time".
I have a table which contains some data. But we are dropped and recreated the same table several times. Now I wanted to know that when this table created initially. How to findout the date of creation(very first time).
I have to create a function. I need to find the max last logout date for each agent daily. For example, if an agent logged in for the first time at 9:00 and he logged out at 12:00 and he logged in again in 14:00 and he logged out at 15:00 the time I need my report to show is 15:00. How can I do that?In order to make it easiest for you to understand I am sending you this query:
select a.login as login2, To_Char(max(s.endtime), 'dd/MM/yyyy, HH24:MI:SS') as lastLogout from cti.agent a inner join cti.agentsessionlog s on s.agentid = a.agentid and To_Char(s.endtime) != '31-DEC-99 11.59.59.000000 PM' group by a.login;
This query returns the agent's login and the agent's last logout time. It works fine if I enter a date between but I cannot do that. If a use this query as it is and I try to export a report for 31/5 it shows as lastlogout the logout for 01/06 or 2/06. Is there a function I can use? I have a deadline.
I want to find the row with invalid day, month which are not matching with calendar day and month. Also the program should capture the data if the year <1900
with xx as (select 101 as ID, '24/05/1899' as create_date from dual union all select 101, '32/03/2012' from dual union all select 102 ,'30/02/2012' from dual union all select 101 , '29/02/2013' from dual
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
I'm posting below test case in which I'm not able to understand output for LAST_VALUE function. I'm expecting maximum value for the salary in a department. Because I'm partitioning by department and ordering a partition as assending so being last value it should give me maximum value within a partition i.e. department in this case.
I was reading a tutorial for analytical function and i found something like this
sum(princial) keep(dense_rank first order by d_date) over partition by (userid, alias, sec_id, flow, p_date)
How to translate this into simple queries / subquery? i am aware that analytical function are faster but i would like to know how this can translate to using query without analytical function.
Is there any way to apply the restriction on analytical functions, just like WHERE and HAVING .AS we know that we can apply the restriction on table by using WHERE and grouping functions by using HAVING clause .
For Ex: Departments wise count including all employees record :
SQL> select count(*) over(partition by deptno) dept_Count, ce.* 2 from scott.emp ce 3 order by deptno, job;
DEPT_COUNT EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO ---------- ----- ---------- --------- ----- ----------- --------- --------- ------ 3 7934 MILLER CLERK 7782 1/23/1982 1300.00 10 3 7782 CLARK MANAGER 7839 6/9/1981 2450.00 10 3 7839 KING PRESIDENT 11/17/1981 5000.00 10 5 7788 SCOTT ANALYST 7566 4/19/1987 3000.00 20 [code]....
