SQL & PL/SQL :: Distinct With Analytical Query And IN Statement?
Nov 18, 2011We'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

SQL & PL/SQL :: How To Retrieve CLOB Data Using DISTINCT Keyword For Other Columns
Aug 2, 2012I have one query regarding how to retrieve the CLOB data.
The requirement is something that in the select statement there are around 20+ columns which i need to retrieve from around 5 tables after joining.
Since the result set after joining also will get duplicate values i need to use distinct keyword to filter the resultset. But in the 20+ columns there are 2 CLOB data columns which i need to retrieve.
Whenever i use DISTINCT i'm getting ORA-00932: inconsistent datatypes: expected - got CLOB error. I know that DISTINCT keyword cannot be used for CLOB datatypes.
SQL & PL/SQL :: LAST-VALUE Analytical Function?
Sep 11, 2012I'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.
CREATE TABLE EMP_MST
(
EMP_ID NUMBER(5),
EMP_NAME VARCHAR2(30),
CONSTRAINT PK_EMP_MST PRIMARY KEY(EMP_ID)

SQL & PL/SQL :: Oracle Analytical Function
Jul 11, 2011Here is the test-table creation script:
CREATE TABLE TEST1 (AGG_DATE DATE, COL1 NUMBER(9), COL2 NUMBER(9), COL3 NUMBER(9));
Here is the test-data population script:
insert into TEST1 (AGG_DATE, COL1, COL2, COL3)
values (to_date('01-01-2012', 'dd-mm-yyyy'), 1, 1, 1);
[code]....
The problem is when I wrote an analytical query, it is giving the BEGIN_DATE and END_DATE by taking all the partition values together and so instead of the values above, it is creating an answer as follows:
Wrong Dataset
BEGIN_DATEEND_DATECOL1COL2COL3
1/1/20121/8/2012111
1/1/20121/8/2012111
1/1/20121/8/2012111
1/1/20121/8/2012111
1/4/20121/11/2012222
1/4/20121/11/2012222
[code]....
Only the last row is correct. What can I do to get the right answer as I know am falling short? Here is my current query:
SELECT MIN(AGG_DATE) OVER(PARTITION BY COL1, COL2, COL3) BEGIN_DATE,
MAX(AGG_DATE) OVER(PARTITION BY COL1, COL2, COL3) END_DATE,
COL1,
COL2,
COL3
FROM TEST1;
SQL & PL/SQL :: Windowing Clause In Analytical Function?
Oct 5, 2010I need to calculate the sum of values over a period of exactly one month (including the current row). Now if I use a windowing clause of "range between interval '1' month preceding and current row", the total period length is 1 month plus one day (being the day in the current record).
Basically, I want to sum over a period starting at "add_months(startdate, -1) + 1" up until startdate of each row.
drop table window_tst;
create table window_tst
( id number primary key
[Code]....
So instead of having 01-feb going back to 01-jan, it should only include 02-jan till 01-feb
I could of course recalculate the period length back to a number of days for each row, but that is not really what I would prefer, as it would make the code rather unreadable.

SQL & PL/SQL :: To_char Function In Combination With Distinct Clause - ORA-00936 / Missing Expression
Mar 2, 2012I have a very simple table with 2 columsn. As_of_date is one of the column. This column is "Date" data type.
When I use distinct clause inside a to_char function it gives the following error:
ORA-00936: missing expression
00936. 00000 - "missing expression"
The Sql is
select to_char(distinct(as_of_date),'mm-dd-yyyy') from sales
I can't see any syntax error in the sql..but forsome reason, it doesn't work.

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.
SQL & PL/SQL :: Restriction On Analytical Functions
Dec 6, 2012Is 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
---------- ----- ---------- --------- ----- ----------- --------- --------- ------

PL/SQL :: Analytical Functions In Group By
Sep 27, 2012I have simplified this for ease of understanding. I have a Data column and a Month_ID column like this:
Values Month_ID
--------- -------------------------------------------------------
AAA 1
BBB 2
I split this out to values per year like this
Value_2011 Value_2012 Month_ID
-------------------------------------------------------------------------
AAA 1
BBB 2
Now i am trying to get the max(Value_2011) keep (dense_rank Last order by Month_ID) but i get a NULL. I can understand its because the Month_ID accomodates all years but i only need it to look at Month_ID for 2011 and return me the last dense_rank value, how can i achieve this?
I tried a couple of different methods like Last_Value() but i have group by in my original statement and i think analytical functions dont like GROUP by if they are not part of it. How can i achieve this?

SQL & PL/SQL :: Analytical Query To Find First And Last Value In Date?
Jul 2, 2013My 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.
My table looks like this.
Input Table:
-----------
CK_IDPI_IDEFF_DT TERM_DT
Mem1ABC1-Jan-1331-Mar-13
Mem1ABC1-Apr-1331-May-13
Mem1ABC1-Jun-1330-Sep-13
Mem1ABC15-Oct-1331-Dec-13
Mem1ABC1-Jan-1431-Mar-14
Mem1XYZ1-Apr-1430-Jun-14
Mem1XYZ1-Jul-1431-Dec-14
Expected Output:
----------------
CK_IDPI_IDEFF_DT TERM_DT
Mem1ABC1-Jan-1330-Sep-13
Mem1ABC15-Oct-1331-Mar-14
Mem1XYZ1-Apr-1431-Dec-14
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))
[code].....
Scripts:
--------------------
Create table lead_test(
CK_ID varchar2(10),
PI_IDvarchar2(10),
EFF_DTDate,
TERM_DT date);
