I have following requirement. Let say i have to generate a range based on "start number" and "end number" dynamically.Some kind of hash buckets.
e.g Start Number : 1 and End Number : 1001.
Also i want to divide that range based on some dynamic value like for above example 10 ranges of 100 each. and both 1 and 1001 should be included only once and the next row start number cannot be same as previous row end number.
Means
Range 1 1 -101
Range 2 102-200
Range 3 201-300
...
Range 10 901-1001
Is there any way of doing it automatically. I tried with Model clause. it works fine for even cases but for odd i have issues also when i take small start and end number i get an error.
SELECT case when ranges=1 then ranges else ranges+1 end Start_Id, ranges+round((1001-1)/10) End_Id

[Code].....
I want this to be generic for any values here 1 is Start Number 1001 is end number and 10 is the bucket. I need these parameters dynamic and want's the same kind of results for any values.
I have a table called 'orders' and having date and time of order placed in the field timeplaced. I need to generate a report which is having hourly based number of orders placed . If no order is placed in an hour then it should show 0 for that hour in the result .
create table orders (order_id integer, timeplaced date,last_updated date);
Insert into ORDERS
(ORDER_ID,
TIMEPLACED, LAST_UPDATED)
Values
(1, TO_DATE('10/11/2011 12:53:39', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('10/11/2011 10:53:39', 'MM/DD/YYYY HH24:MI:SS'));
[code]........
But I need the result for all the 24 hours. Actually row for the hour 1,2,3,4,5,6,8,9,13-23 are not present in the DB

Is there any way to generate columns dynamically by depending on the rows in a table in 11G .
Ex: If the deptno in DEPT table is not constant,then how to generate the N numbers of columns based on the deptno. Below query is working when we hard coded the deptno (10,20,30,40).What else if we more number of departments and we don't know the departments also.

I have a table where i need to update one field values based on another field of the same table , simply as it is.I have done this using one select all check box , on clicking that all check boxes of item_trans table will get selected , then i will un select some of check box and then using one button, i will update the value of the fields which are checked only.
I have put the sample code but when i am updating its taking long time and hanging.I am also attaching the form based on the test case provided.
--tables with insert statement
create table item_trans (trans_item varchar2(12),trans_qty number,trans_act_qty number)
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE1',40,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE2',20,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE3',20,NULL);
--i want to set the value of trans_Act_qty as trans_qty
--i create one dummy or test block to keep the select all check box. for that table test script is
CREATE TABLE TEST
(
C VARCHAR2(2000 BYTE),
B NUMBER,
A NUMBER

insert into test (C,B,A) values ('A',1,1);

I know how to select the last N sets of rows, using DENSE_RANK - where multiple rows have the same timestamp but I want to only select those rows which do NOT have the top 2 unique timestamps.
i.e.:
SELECT *
FROM ( SELECT DENSE_RANK() OVER (ORDER BY myTimestamp DESC) DENSE_RANK, HISTORYID, USER_ID, myTimestamp, STATUS, FROM TXN_HIST)
WHERE DENSE_RANK > 2 order by myTimestamp DESC, HISTORYID, USER_ID;
But how do I DELETE these same rows?
I have the following select query that works perfectly fine. Returns 25 rows based on the descending order of the price.But, I want add one more expression to this list of columns in this query (apart from customer_id).

I have a table ABC with two columns NAME and SEQUENCE. The valid values of sequence are from 1..50. The table may not have all the Sequence number. For example following is the data in my table..

Basically I want to have rows for the sequence numbers which are not present i my table. I thought of using the following query to generate a sequence and then join, but does not work.
select rownum from dual connect by rownum <=50
I tried something like
with temp as (select name, sequence from abc where supp_ref_order is not null order by sequence )
select rownum as num, temp.name from dual, temp connect by rownum <=50 where temp.sequence =num
Even though i am using COL1 CHAR(500) NULLIF COL1=BLANKS, then also i am getting same error for those columns.

Consider tables A,B,C,D,E,F. all are having 100000++ records Tables B,C,D are dependent on table A (with foreign key constraint). When I am deleting records from all tables, table B,C,D are taking max 30-40 seconds while table A is taking 30-40 mins. All tables are having indexes.
Method I have used:
1. Created Temp table
2. then deleted all records from B,C,D,E,F for all records in temp table for limit of 500.
delete from B where exists (select 1 from temp where b.col1=temp.col1);
3. Why it is taking too much time for deleting records in table A.
Is there any thing that during deleting data from such master table, it is referring to all dependent tables even if dependent data is not present ?

how do you generate serial numbers? i have an invoice where i have to add items, so i want the numbering to start from 1 everytime i start a new form and increment by 1 as i i enter a new record. For this i have put my code in when-new-record-instance but problem is if i delete a record and enter a new one, the serial number starts from the nex number.
For ex. if i have 4 items with serial numbers 1, 2, 3, 4 and i delete the item at no. 3 and add a new item , the serial number comes as 5.
proper code to generate the serial numbers?
