How to form this Query

Hi,
A simple requirement... how to get the 5th highest value in a table with a numeric field say 'col1' having random numbers e.g.
12
43
4
656
4
543
99
1
1666
What is the simplest possible query for this?
Thanks,
Cheers,

Prior to Oracle 8i:
SELECT DISTINCT col1
FROM table_name outer
WHERE 5 =
(SELECT COUNT (DISTINCT col1)
FROM table_name inner
WHERE inner.col1 >= outer.col1);For a detailed explanation of the above, see:
http://technet.oracle.com/support/bboard/discussions.htm
With Oracle 8i:
SELECT col1
FROM (SELECT col1, ROWNUM rn
FROM (SELECT DISTINCT col1
FROM table_name
ORDER BY col1 DESC))
WHERE rn = 5;For a detailed explanation of the above, see:

How to modify this query to get the desired output format

I hv written a Query to display all the parent table names and their primary key columns(relevant to this foreign key of the child table).The query is given below...
SELECT DISTINCT(TABLE_NAME) AS PARENT_TABLE,COLUMN_NAME AS PARENT_COLUMN
FROM ALL_CONS_COLUMNS
WHERE CONSTRAINT_NAME IN (SELECT AC.R_CONSTRAINT_NAME
FROM ALL_CONSTRAINTS AC
WHERE AC.TABLE_NAME=TABLE_NAME
AND AC.TABLE_NAME='&TABLE'
AND AC.R_CONSTRAINT_NAME IS NOT NULL);
This query will display all the parent tables and their primary key columns.Now my problem is that how to modify this query to also display the foreign key column name of the child table.
I want the query result in the following format.The query should display the following columns.1)child table's name,2)child table's foreign key column name,3)the corresponding parent table's name,4)the parent table's primary key column name(which is the foreign key in the child table).
For Example I want the output as follows...
TAKE THE CASE OF SCOTT.EMP(AS INPUT TO YOUR QUERY)
CHILD_TABLE CHILD_COLUMN PARENT_TABLE PARENT_COLUMN
EMP DEPTNO DEPT DEPTNO
In this result I hv used alias name for the columns.The query should display this only for the foreign keys in the child table.In the query which I sent to you earlier will give the parent table and the parent column names,But I also want to append the child table and child column names there.
any help on how to tackle would be appreciated.

Try this query
SELECT c.table_name child_table,
     c.column_name child_column,
     p.table_name parent_table,
     p.column_name parent_column
FROM user_constraints a,user_constraints b,user_cons_columns c,
     user_cons_columns p
WHERE a.r_constraint_name=b.constraint_name and
      a.constraint_name=c.constraint_name and
      b.constraint_name=p.constraint_name and
      c.position=p.position
ORDER BY c.constraint_name,c.position

The only difference which i am seeing in your queries is the Operation ('6910', '6912','7344','8344')
Then why don't you put all values in One like this
Select facility, route, operation, script_id
from F_ROUTEOPER
where facility = 'A01' and operation in *('6910', '6912','7344','8344','7976')* AND src_erase_date is null
and (script_id not in ('PHQ-LOTCHKRV','PHQ-LOTCHK') or script_id is null)
AND (route NOT LIKE '9EL%' AND route NOT LIKE '9TB%'AND route NOT LIKE 'BLB%' AND route NOT LIKE 'BWR%' AND route NOT LIKE 'CRL%')
Hope this will resolve your problem.

As well as EXPLAIN PLAN, let us know what proportion of rows are visited by this query. It may be that it is not using a full table scan when it should (or vice versa).
And of course we'd need to know what indexes are available, and how selective they are for the predicated you have in this query ...

How to write this query to filter combination of few values

Hi,
I have a table CHIMM which is a transaction table and contains information of the vaccines given to a child.
columns are: child_id, vacc_id, vacc_given_dt. I have to query for remaining vaccines.
HEXA is a vaccine_id which is composite vaccine of DPT1,POL1,HBV1 & HIB1 (vaccine ids).
I want to write to query if any of DPT1,POL1,HBV1 & HIB1 given then HEXA should not be displayed in the result.
OR
if HEXA is given then of course any of DPT1,POL1,HBV1 & HIB1 should not be displayed in the result.
How to write this query?

Hi,
I'm still not sure what the output you want from that sample data is. Do you just want the child_ids, like this
CHILD_ID
       3
       4? If so, here's one way to get them:
WITH     all_vacc_ids     AS
     SELECT     c.child_id
     ,     c.vacc_id          AS child_vacc_id
     ,     v.vacc_id
     ,     COUNT ( CASE
                         WHEN c.vacc_id = 'HEXA'
                   THEN 1
                     END
                )       OVER ( PARTITION BY c.child_id
                                   )    AS hexa_itself
     FROM          vacc   v
     LEFT OUTER JOIN     chimm c     PARTITION BY (c.child_id)
                      ON     c.vacc_id     = v.vacc_id
     WHERE   v.vacc_desc       = 'HEXA'     -- See note below
SELECT       child_id
FROM       all_vacc_ids
WHERE       child_vacc_id     IS NULL
AND       vacc_id     != 'HEXA'
AND       hexa_itself     = 0
GROUP BY child_id
rha2 wrote:there are alot of vaccines, i just put 3 for example. this query gives error: invalid relational operatorAre you saying that the vacc table contains other rows, but those other rows are not needed for this problem? It would be good if you included an example in the sample data. The query above considers only the rows in vacc where vacc_desc='HEXA'. You can have other rows in the vacc table, but they won't affect the output of this query. The query above makes no assumptions about the number of rows that have vacc_desc='HEXA'; it will report all child_ids who are missing any of them, regardless of the number (assuming the child does not have the 'HEXA' vacc_id itself, like child_id=1).
You still haven't said which version of Oracle you're using. The query above will work in Oracle 10 (and higher).

list the emp name who is working for the highest avg sal department.
I can use row_number over to get correct result. If we don't use this row_number function, just plain sql, how to do it ?
the row_number version is like this

select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno

and emp.deptno = e.deptno

ROW_NUMBER (or its close relative, RANK) is the simplest and most efficient way to solve this problem. Why not do this the right way?
the row_number version is like this
select emp.* from emp ,
select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno
)e
where e.r = 1
and emp.deptno = e.deptno
If there happens to be a tie (that is, two or more departments have the same average sal, and it is the highest), then the query above will only arbitrarily treat one of them (no telling which one) as the highest. Change ROW_NUMBER to RANK to get all departments with a claim to having the highest average sal.
You could use the ROWNUM pseudo-column instead of ROW_NUMBER, if all you want to do is avoid ROW_NUMBER.
Without using ROW_NUMBER or RANK, there are lots of ways involving other analytic functions, such as AVG and MAX.
If you really, really don't want to use analytic functions at all, you can do this:
SELECT     *
FROM     scott.emp
WHERE     deptno     IN (
                  SELECT       deptno
                  FROM       scott.emp
                  GROUP BY deptno
                  HAVING       AVG (sal) = (
                                                   SELECT    MAX (AVG (sal))
                                           FROM          scott.emp
                                           GROUP BY deptno

How to update this query and avoid performance issue?

Hi, guys:
I wonder how to update the following query to make it weekend day aware. My boss want the query to consider business days only. Below is just a portion of the query:
select count(distinct cmv.invoicekey ) total ,'3' as type, 'VALID CALL DATE' as Category
FROM cbwp_mv2 cmv
where cmv.colresponse=1
And Trunc(cmv.Invdate) Between (Trunc(Sysdate)-1)-39 And (Trunc(Sysdate)-1)-37
And Trunc(cmv.Whendate) Between cmv.Invdate+37 And cmv.Invdate+39the CBWP_MV2 is a materialized view to tune query. This query is written for a data warehouse application, the CBWP_MV2 will be updated every day evening. My boss wants the condition in the query to consider only business days, for example, if (Trunc(Sysdate)-1)-39 falls in weekend, I need to move the range begins from next coming business day, if (Trunc(Sysdate)-1)-37 falls in weekend, I need to move the range ends from next coming business day. but I should always keep the range within 3 business days. If there is overlap on weekend, always push to later business days.
Question: how to implement it and avoid performance issue? I am afraid that if I use a function, it greatly reduce the performance. This view already contains more than 100K rows.
thank you in advance!

You are already using a function, since you're using TRUNC on invdate and whendate.
If you have indexes on those columns, then they will not be used because of the TRUNC.
Consider omitting the TRUNC or testing with Function Based Indexes.
Regarding business days:
If you search this forum, you'll find lots of examples.
Here's another 'golden oldie': http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:185012348071
