Needs Help In Constructing SQL Query

Will you please help me in retrieving 3 rd 4 th n th highest salary record from employee table?

Or
select ename,sal,r from (
select ename,sal,rownum r
from ( select ename,nvl(sal,0) sal from emp order by 2 desc)
where r in (3,4)
/It just depends what you exactly mean 3rd and 4th? - the above gives the employees in position 3 and 4 but employee in position 5 may have the same salary too. The previous answer looks at the distinct salaries of the company and returns the employees on that salary so you could get more than 2 employees. Both answers are correct depending on what the original question was hence why analysts get more than coders IMHO.

Newbie - need help with a SQL query for a bar chart

Hi,
I'm a new user on APEX with no real SQL knowledge and I'm trying to build a dashboard with charts into an existing APEX application. Based on another application, I have come up with the following SQL code:
select null link
, CATEGORY label
, count (decode(PROJECT_STATUS,'1',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'2',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'3',PROJECT_ID))"On Hold"
, count (decode(PROJECT_STATUS,'4',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'5',PROJECT_ID))"Pending Review"
from GRAPO_PROHEADTRK
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')
group by CATEGORY
Order by COUNT(PROJECT_ID) DESC
The code from the other app was:
select null link
, FUNCTIONAL_AREA label
, count (decode(PROJECT_STATUS,'Active',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'Complete',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'On Hold',PROJECT_ID)) "On Hold"
, count (decode(PROJECT_STATUS,'Recurring',PROJECT_ID))"Recurring"
, count (decode(PROJECT_STATUS,'Pipeline',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'Not Approved',PROJECT_ID))"Not Approved"
from PM_V2
where LOB='S2S' and (FUNCTIONAL_AREA='Accounts Payable' or FUNCTIONAL_AREA='Expense' or FUNCTIONAL_AREA='Procurement' or FUNCTIONAL_AREA='Fixed Assets')
group by FUNCTIONAL_AREA
Order by COUNT(PROJECT_ID) DESC
I'm getting a "Failed to parse SQL query!" error when I try to run validation.
Is this enough info for some assistance? Any help would really be appreciated.
Thanks,
Rachel

Hello,
This is more of an SQL question, rather than specifically APEX-related. It's notable that you say: I'm a new user on APEX with no real SQL knowledgeWhich is fine (we all have to start somewhere, afterall) but it might be worth de-coupling the problem from APEX in the first instance. I'd also strongly recommend either taking a course, reading a book (e.g. http://books.google.co.uk/books?id=r5vbGgz7TFsC&printsec=frontcover&dq=Mastering+Oracle+SQL&hl=en#v=onepage&q=Mastering%20Oracle%20SQL&f=false) or looking for a basic SQL tutorial - it will save you a whole lot of heartache, I promise you. Search the oracle forums for the terms "Basic SQL Tutorial" and you should come up with a bunch of results.
Given that you've copied your query template from another, I would suggest ensuring that the actual query works first of all. Try running it in either:
* SQL Editor
* SQL*Plus
* an IDE like SQL Developer (available free from the OTN: http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html ) or TOAD or similar.
You may find there are syntax errors associated with the query - it's difficult to tell without looking at your data model.
select null link
, CATEGORY label
, count (decode(PROJECT_STATUS,'1',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'2',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'3',PROJECT_ID))"On Hold"
, count (decode(PROJECT_STATUS,'4',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'5',PROJECT_ID))"Pending Review"
from GRAPO_PROHEADTRK
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')
group by CATEGORYNote that your "order by" clause references a field called "PROJECT_ID", which exists in the old query but you've changed other similar references to "PROJECT_STATUS" - is it possible you've just missed this one? The perils of copy-paste coding I'm afraid...

Need help on oracle sql query

Hi team,
Please help me on below query,
I have table like given below
Tran_Id tran_date   amount. Actorid
   1.         10-apr-15.   100.         1
   2.         11-apr-15.   100.         1
   3.         11-apr-15.   900.         1
   4.         12-apr-15.   100.         1
   5.         13-apr-15.   350.         1
   6.         14-apr-15.   400.         1
Now please find the query,
I want all the actor ids whos tran amount
>1500 and the date when the tran amount
Has breached
Ex:
Actor-id. Breached-date.    Total
1.              13-apr-15.            1900
How can I write a query for above requirement?
Regards,
Rajendra

Your solution (same as Saubhik's) is incorrect. Look at source data - multiple transactions can occur same day. Therefore, your qury will return wrong results if breached amount is 1000:
with trans as (
select 1 tran_Id, to_date('10-apr-15', 'dd-mon-yy') tran_date, 100 amount, 1 actorid from dual union all
select 2, to_date('11-apr-15', 'dd-mon-yy'), 100, 1 from dual union all
select 3, to_date('11-apr-15', 'dd-mon-yy'), 900, 1 from dual union all
select 4, to_date('12-apr-15', 'dd-mon-yy'), 100, 1 from dual union all
select 5, to_date('13-apr-15', 'dd-mon-yy'), 350, 1 from dual union all
select 6, to_date('14-apr-15', 'dd-mon-yy'), 400, 1 from dual union all
select 7, to_date('12-apr-15', 'dd-mon-yy'), 300, 2 from dual union all
select 8, to_date('13-apr-15', 'dd-mon-yy'), 1200, 2 from dual union all
select 9, to_date('14-apr-15', 'dd-mon-yy'), 300, 2 from dual union all
select 10, to_date('15-apr-15', 'dd-mon-yy'), 300, 2 from dual
trans_running_tot as (
select tran_id, tran_date,
sum(amount) over (partition by actorid order by tran_date) tot_amt, actorid
from trans
trans_ranked as (
select actorid,tran_id, tran_date,
rank() over (partition by actorid order by tot_amt) rk
from trans_running_tot
where tot_amt > 1000
select * from trans_ranked where rk=1
   ACTORID    TRAN_ID TRAN_DATE         RK
         1          2 11-APR-15          1 -- here total amount was only 200
         1          3 11-APR-15          1
         2          8 13-APR-15          1
SQL>
As you can see, 2 rows were returned for actor 1. Why? Default for analytic ORDER BY is RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW. Therefore, all rows with same transation_date will fall into same window:
SQL> with trans as (
2   select 1 tran_Id, to_date('10-apr-15', 'dd-mon-yy') tran_date, 100 amount, 1 actorid from dual union all
3   select 2, to_date('11-apr-15', 'dd-mon-yy'), 100, 1 from dual union all
4   select 3, to_date('11-apr-15', 'dd-mon-yy'), 900, 1 from dual union all
5   select 4, to_date('12-apr-15', 'dd-mon-yy'), 100, 1 from dual union all
6   select 5, to_date('13-apr-15', 'dd-mon-yy'), 350, 1 from dual union all
7   select 6, to_date('14-apr-15', 'dd-mon-yy'), 400, 1 from dual union all

11   select 10, to_date('15-apr-15', 'dd-mon-yy'), 300, 2 from dual
12   )
13 select tran_id, tran_date,
14    sum(amount) over (partition by actorid order by tran_date) tot_amt, actorid
15 from trans
16 /
   TRAN_ID TRAN_DATE    TOT_AMT    ACTORID
         1 10-APR-15        100          1
         2 11-APR-15       1100          1
         3 11-APR-15       1100          1
         4 12-APR-15       1200          1
         5 13-APR-15       1550          1

         9 14-APR-15       1800          2
        10 15-APR-15       2100          2
10 rows selected.

So correct solution is to ORDER BY transation id. Also, just in case if amount can be 0, we should add tranaction id when ordering by sum:
with trans as (
select 1 tran_Id, to_date('10-apr-15', 'dd-mon-yy') tran_date, 100 amount, 1 actorid from dual union all
select 2, to_date('11-apr-15', 'dd-mon-yy'), 100, 1 from dual union all
select 3, to_date('11-apr-15', 'dd-mon-yy'), 900, 1 from dual union all
select 4, to_date('12-apr-15', 'dd-mon-yy'), 100, 1 from dual union all
select 5, to_date('13-apr-15', 'dd-mon-yy'), 350, 1 from dual union all
select 6, to_date('14-apr-15', 'dd-mon-yy'), 400, 1 from dual union all
select 7, to_date('12-apr-15', 'dd-mon-yy'), 300, 2 from dual union all
select 8, to_date('13-apr-15', 'dd-mon-yy'), 1200, 2 from dual union all
select 9, to_date('14-apr-15', 'dd-mon-yy'), 300, 2 from dual union all
select 10, to_date('15-apr-15', 'dd-mon-yy'), 300, 2 from dual
trans_running_tot as (
select tran_id, tran_date,
sum(amount) over (partition by actorid order by tran_id) tot_amt, actorid
from trans
trans_ranked as (
select actorid,tran_id, tran_date,
rank() over (partition by actorid order by tot_amt,tran_id) rk
from trans_running_tot
where tot_amt > 1000
select * from trans_ranked where rk=1
   ACTORID    TRAN_ID TRAN_DATE         RK
         1          3 11-APR-15          1

Need help on a sql query

Hi Friends,
I am trying to load Employees and their Assignments using APIs.
I have various columns in my staging table like Last Name, First Name, etc., but I need help in writing query in the cursor especially for columns Emp Number and Supervisor Number.
I have data as below
Emp_Number     Supervisor_Number
GE0002               GE0064
GE0064               EG0009
EG0009               EG0001
100009                EG0001
EG0001               TU0001
Cursor I write will process the data in the same order as above, but here the problem is...
When it processes first row, it checks for supervisor GE0064 which do not exist and so it errors out.
Similarly for second row, it checks for supervisor EG0009 which again do not exist and so it errors out.
So in order to prevent this, the cursor should process the rows as below
Emp_Number     Supervisor_Number
EG0001               TU0001
EG0009               EG0001
GE0064               EG0009
GE0002               GE0064
100009                EG0001
By this way, Supervisor should be defined first as an employee and then it can be used as a supervisor for other employees
is there a way that I can get the output as above(second set of data), when the table has records randomly as above(first set of data)
Appreciate your help!
Thanks,
Srikanth

Why did the number go up?
It's something only you can find out
Maybe some Emp have several Supervisor(s) like
with
t as
(select 'GE0002' Emp,'GE0064' Supervisor from dual union all
select 'GE0064','EG0009' from dual union all
select 'EG0009','EG0001' from dual union all
select 'GE0064','100009' from dual union all
select '100009','EG0001' from dual union all
select 'EG0001','TU0001' from dual
select Emp,Supervisor,lpad('_',3 * (level - 1),'_')||Emp indent
from (select Emp,Supervisor
          from t
        union all
        select supervisor,null
          from t tt
         where not exists(select null
                            from t
                           where emp = tt.supervisor
start with Supervisor is null
connect by prior Emp = Supervisor

Need help on small sql query

Hi,
I have a requirement where I need to show 'F&D' string. I can explain this by below query.
select 'F&D' from dual
but when I run this query, toad prompts me to enter value for &D variable :( But my requirement is to show 'F&D' string.
Can anyone please tell me what modification needs to be done to above query to get string 'F&D' as output.
I know work around for this as below.
select 'F'||chr(38)||'D' from dual
I want permenant solution for this. Can anyone please help me?

Need help creating large SQL query

I am trying collect the sum of records that have a cancelled event prior to the Arrive event. The solution needs to be within the Sum function. Any ideas would be helpful
The structure of the table is as follows
1. Record_Num(primary): varchar
2. Event_Type: varchar
3. Time: timestamp
Each record number can contain multiple events, hence the issue with specifiying the time for an event of 'Arrive' and an event of 'Canceled'
This is part of a much bigger query, here's what that looks like:
Select
Sum(Case when di.calltype = 'Missed' then 1 else null end) as "Canceled Prior To Liftoff",
Sum(Case
when dt.eventtype = 'Canceled' Then 1
when
(select to_char(dt.datetimestamp, 'HH:MI:SS')
from progpennstar.dispatchtime dt
where Lower(dt.eventtype) in 'aborted')
< any (select to_char(dt.datetimestamp, 'HH:MI:SS')
from progpennstar.dispatchtime dt
where dt.eventtype in 'Arrive Locale')
Then 1
Else null end) as "Canceled Enroute to Call"
From progpennstar.dispatch di, progpennstar.dispatchtime dt
where di.dateoftransport >= to_date('07/01/2008', 'MM/DD/YYYY') and
di.dateoftransport <= to_date('09/30/2008', 'MM/DD/YYYY') and
di.dispatch_id = dt.dispatch_id

to the op: I think SomeoneElse already got the solution, I just want to add a few minor points. You can replace the ANY construct (which is rarely used) with a simple comparison. In general ANY constructs are more difficult to understand. Check if the correct logic is applied.
SELECT SUM(CASE
               WHEN di.calltype = 'Missed' THEN 1
               ELSE NULL
           END) AS "Canceled Prior To Liftoff"
      ,SUM(CASE
               WHEN dt.eventtype = 'Canceled' THEN 1
               WHEN dt.eventtype = 'Aborted'
               AND exists (SELECT null
                                    FROM dispatchtime dt2
                                    WHERE dt2.eventtype IN 'Arrive Locale'
                                    AND dt2.dispatch_id = di.dispatch_id
                                    AND dt.datetimestamp < dt2.datetimestamp /* this is the new comparison */
                     THEN   1
               ELSE NULL
           END) AS "Canceled Enroute to Call"
FROM   dispatch di,
       dispatchtime dt
WHERE di.dateoftransport >= to_date('07/01/2008', 'MM/DD/YYYY')
AND    di.dateoftransport < to_date('09/30/2008', 'MM/DD/YYYY') /* Carefull! I changed <= to <. Do you want to include the full last day or only midnight? */
AND    di.dispatch_id = dt.dispatch_id;I also changed the alias of the remaining subquery so that different aliases are used.

Hi James
Please provide me the following information.
1)What is the version of crystal reports you are using?
2)Whcih database & connection type are you using?
3)Does this query take 75 mins to run in Crystal reports designer?
4)How much time does it take at your database end?
5)How many records are fetched by this query?
6)Looking at the query it shows that it is using case statements and few joins for restricting the data.
7)Please use the same query in a command object in Crystal reports designer and check the result.
Thanks

Hi,
There are a lot of questions regarding this kind of functionality in the forums can you please have a look at the forum. The latest one which has something similar to your requirement is

That's called String Aggregation , and how to do it depends on your version of Oracle, and your exact requirements.
See thie following page for several techniques:
http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php
If you're using Oracle 10 (or higher), and it's important that the name_a's be in order in the output, then you can do this:
WITH     got_r_num     AS
     SELECT     name_a
     ,     intid
     ,     ROW_NUMBER () OVER ( PARTITION BY intid
                               ORDER BY         name_a
                       )         AS r_num
     FROM     order_table                    -- ORDER is not a good table name
     WHERE     intid     IN (1)                    -- Optional
SELECT     intid
,     SUBSTR ( SYS_CONNECT_BY_PATH (name_a, ',')
            , 2
            )     AS name_a_list
FROM     got_r_num
WHERE     CONNECT_BY_ISLEAF     = 1
START WITH     r_num     = 1
CONNECT BY     r_num     = PRIOR r_num + 1
     AND     intid     = PRIOR intid
;Starting in Oracle 11.2, LISTAGG is better.
This does not assume that you are getting the output only for a single intid at a time. You can get any number of them in a suingle query. Of course, that number can be 1 if that's what you want.

Need Help with Advanced SQL Query

It's advanced for me, at least. I have three tables that I
need to use:
Product (product_id and product_title are the fields)
shipRegion (shipRegion_ID)
product_shipRegion_shipCharge (product_id, shipRegion_ID,
primaryShipCharge, secondaryShipCharge)
What I am trying to do is create a query that will look for
two things:
1. Any product that is listed in the
product_shipRegion_shipCharge table that has a primary or secondary
ship charge of $0.00 or is NULL.
That part is easy:
SELECT DISTINCT p.product_id, p.product_title
FROM product p
INNER JOIN product_shipRegion_shipCharge pss ON p.product_id
= pss.product_id AND (pss.primaryShipCharge IS NULL OR
pss.primaryShipCharge = 0 OR pss.secondaryShipCharge IS NULL OR
pss.secondaryShipCharge = 0)
WHERE p.display = 1
AND p.price > 0
It's this next part that's tricky for me:
2. Get the product_id and product_title (from the product
table) that does NOT have any entry in the
product_shipRegion_shipCharge table.
I'm guessing that I need to include some kind of LEFT JOIN in
the above query to find out what all of the regions are (from the
shipRegion table) and then see what's missing for each product in
the product_shipRegion_shipCharge table, but I have no idea how to
do it.
Anyone?
Josh

This should be what the query would look like using the left
join:
SELECT product_table.product_id, product_table.product_title
FROM product_table
LEFT OUTER JOIN product_shipRegion_shipCharge
ON product_shipRegion_shipCharge.product_id =
product_table.product_id
WHERE product_shipRegion_shipCharge. product_id IS NULL
SQL Server's query optimizer will probably turn the '...IN
(subquery)' or '...exists (subquery)' into this kind of execution
plan on its own - depending on your table structures.

SQL Gurus : Need Help in building SQL query

SQL Gurus,
Need your expertise to solve my below problem:
- I have a column that had comma separated data, basically there are the levels in a hierarchy. eg The same column could have the following data:
Row 1: R1L1, R1L2, R1L3
Row 2: R2L1, R2L2
Row 3: R3L1, R3L2, R3L3, R3L4
For assumption purpose lets assume that there are maximum 5 Levels
I want to put this data from this column into another table which holds the levels. I am expecting the output in another table as follows:
Col1____Col2 ____Col3____Col4____Col5
Row 1: R1L1___R1L2____R1L3____null_____null
Row 2: R2L1___R2L2____null_____null_____null
Row 3: R3L1___R3L2____R3L3____R3L4___null
How do i achieve this ? ie coverting the comma separated values in a column to separate columns. The # of values in each columns could be different as I have showb above

Need help in this sql query to use Case Statement

hi All,
I have the below query -
SELECT DISTINCT OFFC.PROV_ID
,OFFC.WK_DAY
,CASE
WHEN OFFC.WK_DAY ='MONDAY' THEN 1
WHEN OFFC.WK_DAY ='TUESDAY' THEN 2
WHEN OFFC.WK_DAY ='WEDNESDAY' THEN 3
WHEN OFFC.WK_DAY ='THURSDAY' THEN 4
WHEN OFFC.WK_DAY ='FRIDAY' THEN 5
WHEN OFFC.WK_DAY ='SATURDAY' THEN 6
WHEN OFFC.WK_DAY ='SUNDAY' THEN 7
END AS DOW
,OFFC.OFFC_OPENG_TIME
,OFFC.OFFC_CLSNG_TIME
FROM GGDD.PROV_OFFC_HR OFFC
WHERE OFFC.PROV_ID='0000600'
WITH UR;
this query is bringing results in 6 differnt rows with opening and closing time for each day separately. I want to generate the data in one row with each day having opening and closing time, so for 7 days, total 14 columns with opening and closing time. But i am not able to do that using case statement.
can somebody help me in achieving that.
thanks,
iamhere

Hi,
Welcome to the forum!
That's called a Pivot .
Instead of having 1CASE expression, have 14, one for the opening and one for the closing time each day, and do GROUP BY to combine them onto one row.
SELECT       OFFC.PROV_ID
,       MIN (CASE WHEN OFFC.WK_DAY ='MONDAY'    THEN OFFC.OFFC_OPENG_TIME END)     AS mon_opn
,       MIN (CASE WHEN OFFC.WK_DAY ='MONDAY'    THEN OFFC.OFFC_CLSNG_TIME END)     AS mon_cls
,       MIN (CASE WHEN OFFC.WK_DAY ='TUESDAY'   THEN OFFC.OFFC_OPENG_TIME END)     AS tue_opn
,       MIN (CASE WHEN OFFC.WK_DAY ='TUESDAY'   THEN OFFC.OFFC_CLSNG_TIME END)     AS tue_cls
FROM        GGDD.PROV_OFFC_HR OFFC
WHERE       OFFC.PROV_ID     = '0000600'
GROUP BY offc.prov_id
;This assumes there is (at most) only one row in the table for each distinct prov_id and weekday. If not, what do you want to do? Post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
The staement above works in Oracle 8.1 and up, but there's a better way (SELECT ... PIVOT) available in Oracle 11. What version are you using? (It's always a good idea to include this when you post a question.)

Please need help on this SQL query ..

hi peers,
here is my situation :
Field1 Field2 Field3
xa group1 req_id1
xb group2 req_id2
xc group3 req_id3
xa group4 req_id4
xb group5 req_id5
i need to pull only the group3 record that comes right away after group2. Req_id's are in chronological order and groupx are texts
: i.e : req_id1 < req_id2 < req_id3 <.....
in other terms, i need the record that comes after the re cord flagged by group2..knowing that req_id3 is right after req_id2.
any thoughts ?
thanks

Hi,
Use the analytic LAG function to get a value from an earlier row:
WITH     got_prev_field2     AS
     SELECT     field1, field2, field3
     ,     LAG (field2) OVER (ORDER BY field3)     AS prev_field2
     FROM     my_situation
SELECT     field1, field2, field3
FROM     got_prev_field2
WHERE     prev_field2     = 'group2'
;Like all analytic functions, LAG is computed after the WHERE clause is applied. To use the value returned by LAG in a WHERE clause, we have to compute it in a sub-query.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data.

ORA-00907: missing right parenthesisIf you use something like SQL*Plus or SQL Developer, they will give you the error stack which will point you to the source of the problem.
It's saying missing right parenthesis. Start by finding out if we've got all out matching brackets. Counting from the start of that statement i.e. SUBSTR on line 12, we have 7 open brackets and 6 close brackets. So there does appear to be a problem with brackets. However if we take a step back and look at lines 12 to 16, this is actually a single statement. It's a call to the SUBSTR function and within it it has calls to RTRIM, XMLAGG etc. For the statement as a whole there are the same number of left and right parenthesis so the problem is related to something else. Something that is leading the syntax check to think it has reached the end of a statement and hasn't found enough closing parethesis.
The issue here appears to be that we have the token PCNAMES at the end of line 13 but syntactically that's not correct. We can't have that token there because it's appearing in the middle of a function call. PCTNAMES is actually a column alias but it's just in the wrong place. We need it to be an alias for the whole expression from line 12 to 16. So make the change and see what happens...

ERROR at line 14:
ORA-00907: missing right parenthesisNOw we've got a new error. Again it's saying we've got a missing parenthesis but this time on line 14. The issue here is that line 13 is a parameter to the SUBSTR function but there is no comma on the end. What we actually have at the moment is a line that looks like so
RTRIM(XMLAGG(XMLELEMENT(e,PC_NAME || ',' || SUBSTR(VALUE,1,LEN(VALUE) - 2),',').EXTRACT('//text()')),',') 2,Which is just not formed correctly. We need a comma at the end of line 13 to state that this is the end of that line as a parameter.
