I have need, where I need to pick-up the one of the records out of 2, which have all the fields same but one key column? how should I do it?
sample data:
IDnamecreation dateupdate date
121233ATR7/19/2010 15:307/19/2010 15:30
1213344MTR7/19/2010 15:307/19/2010 15:30
For most of the cases, i am picking latest data using update date, but here where dates are same, I am stuck.
create table test1(x number, y date)
insert into test1 VALUES (1, '01-OCT-2010');
insert into test1 VALUES (1, '01-OCT-2010');
insert into test1 VALUES (1, '01-OCT-2010');
insert into test1 VALUES (1, '01-OCT-2010');
insert into test1 VALUES (1, '01-OCT-2010');
insert into test1 VALUES (1, '01-OCT-2010');
insert into test1 VALUES (1, '01-OCT-2010');

I need an sql which would pick 3% of the records per day
select count(*), y from test1
group by y
21 10/1/2010
14 10/2/2010
6 10/3/2010
So I need 3% of 21 (.63) randomely picked up for 10/1.
similarly 3% of total number of rows from 10/2, 10/3 to be picked up.
I have a reqmt that is little complex.
Example: (Real Data)
Table1 (Column Name)
Height
Width
Color
Table2
ID,Height, Width, Color, Remarks
1,2,3,NULL,NULL
2,NULL,NULL,2,NULL
3,1,2,3,4
What I require is pick up the data from table1 and for each row in table1, check the corresponding column to see if null. If null create a counter and add 1 to it.
I would only check for 1 record at a time in table2 (ID is input parameter in pl/sql) In other words, if my ID is 1, my count should be 1 (since COLOr is null in table2 for id=1 and color is a row in table1) if my id is 2, count is 2 (ht and width are NULL and are both separate rows in table1) if id is 3, count=0 since all fields have data even though some of these columsn exists as rows in table1.
I need to pick a value based on range like if the range is as below
[code]
if value =2000 then its 2000
elsif value >=2001 and value <=2499 it should be 2000
elsif value =2500 then 2500
elsif value >=2501 and value <=2999 it should be 2500
elsif value = 3000 then it should be 3000
[code]
Like this i need to pick a value by hardcoding this range and this look cumbersome in my program , is there a simple way to substitute this entire thing by passing one single value and getting one single value using a command or builtin.
i have to pick single value from the given range based on value entered by user, for example if user enter the length 2499 it should be considered as 2000 if he enters 2000 its 2000 or he enters 2501 it will return 2500 , i have written a huge if condition for this purpose in my program which looks very cumbersome,is there a simple to do this other than this method.
the code is as below.
[CODE]
IF
( :CSDO_STORE_RECD_LENGTH - SUBSTR(:CSDO_STORE_RECD_LENGTH,(LENGTH(:CSDO_STORE_RECD_LENGTH)-1),LENGTH(:CSDO_STORE_RECD_LENGTH))) =2000
THEN M_RCVD_LENGTH := 2000;
ELSIF

I got a situation to develop a complex query. Here is the scenario. I have to pick all the continues range of values into one bundle. like in following example, rows having values between 20 to 25 should have one bunch and 27 to 28 should have another as there is no from or to value from 25 to 28. with q1 ( select 20 as Frm, 25 as tto from dualunion allselect 20 as Frm, 21 as tto from dualunion allselect 20 as Frm, 22 as tto from dualunion allselect 20 as Frm, 20 as tto from dualunion allselect 21 as Frm, 22 as tto from dualunion allselect 28 as Frm, 28 as tto from dualunion allselect 27 as Frm, 28 as tto from dual)select * from q1;

Am working on a workbook to count the number of enrolments and withdrawals in the program. My data looks like this
name semester status year
A 1 enrol 2010
A 2 withdraw 2010
A 3 enrol 2010
B 1 enrol 2010
B 2 withdraw 2010
I want to count their latest status only. It should come up with
Total Enrol - 2
Total Withdrawn - 1
For total Withdrawn, I tried 'rank' and filter to equals 1 but it does not allow me. Is there any way to have this work?
Here's my calculation:(decode((FIRST_VALUE(status) OVER(PARTITION BY year, name ORDER BY semester DESC)),'withdraw', name)) It tells me that 'Aggregation of Analytic function not allowed'

I do not want :

SO far I am using the following but since I am dealing with hundreds of column that has the same material, when using listagg() from oracle 11.2g, they column width is too wide to fit into the required column.
update eris_data_work e set E.flex37 =

I have a table1:
userid, name, town.
Now i want to do a self join like:
select a.name, b.name, a.town
from table1 a
inner join table1 b
on a.town = b.town
where a.first_name <> b.first_name AND
a.last_name <> b.last_name
i added the where clause to limit duplicates i would get but i still get duplicates eg. A B london, B A london etc.
I have to load 50 Million records in a table. I also need to ensure that no duplicate records enter. Business demand is that It may send 2 Million records today, 1 Million records tomorrow, 3 million records on the next day and so on...
I have loaded 6 Million records into the table, but onwards speed of loading records (with duplicate check) is decreasing.
db and dev 10g rel2 ,suppose that i have a table with a lot of duplicate rows ,what i need is to delete the duplicates and retain one row of these duplicates . likecolumn -- with those values...how to delete two (hi's) and retain the third , ?it is all applied to all the duplicate values in the column.

I tried with MAX and DENSE_RANK but its not getting me the first row.
I ran an Inner Join but it returned many, many duplicates. One Answer from a different thread:Because you may be having improper Join condition what has a One to many or a Many to many relationship between the tables. We do not have the data, and hence cannot comment over it. What do I look for to identify an improper join?

My Requirement is:

This should apply to all the values in column MAIN_TABLE
I'd like to achieve the following (and YES, I do know that this is not multi-user safe, but that's not the point here):
Before inserting a record, the trigger shall check if there's already a duplicate one. Duplicate means in this case when there is an intersection of the time frame, defined by two numeric timestamps. That's also the cause why I cannot use a simple UNIQUE constraint here (in my opinion).
Okay, that already works (see code below). But now I need colliding records to be written to a temporary table so that those records can be returned and presented to the user for selection.

I have a table like this basic example:
ID Product Color Time-In
1 Apple Green May
2 Apple Red April
3 Pear Green May
4 Pear Green April
5 Plum Blue June
In SQL I want to return all 4 fields of the records except those records where Product and Color are identical - in that case it should return the latest (by name of month - preferred) or just the first it finds
So I should get these
1 Apple Green May
2 Apple Red April
3 Pear Green May
5 Plum Blue June
If I do a select distinct then I will only get those fields I test on (product and color), not the rest.

I am trying to work with query to get distinct unique records, following is my scenerio:

From the above duplicates I would like to get only 1 distinct record based on latest update time (when using distinct on a sub-query since OBID is unique again returning all recds)

I have this query that returns results that contain duplicates(somewhat). I only want either the FIRST or LAST (either one is fine). Here is the query:
select unique PLLA.attribute4, PLA.item_description from po_lines_all PLA, po_line_locations_all PLLA
where PLLA.po_line_id = PLA.po_line_id
and PLLA.attribute4 is not null
So my output is something like this:
RCE12 This is an item for AUL1
RCE13 This is an item for PWEILL
RCE14 This is an item for AUL1
I just want either the RCE12 or RCE14 record and not both since they both have the same description.
