Selecting the rows with the max rank

Using Siebel CRM and tested conditions in Answers - It was observed that one email ID is linked to multiple customers. For an email campaign we need to select only one customer per email basically had to remove all the duplicate email addresses from the list as customer IDs are anyways unique.
Tried using the RANK function - RANK(customer ID by Email) = 1 it gave me unique email addresses and customer IDs but the problem is that the RANK 1 is given to the latest customer added (customer IDs are numeric)
I need a solution to select all the rows with the max rank / all the customers that were added first for all the emails

Don't know what you want to achieve but here is way to do this:
SQL> select * from test;
NO
1
2
3
4
5
SQL> select * from test union all select * from test;
NO
1
2
3
4
5
1
2
3
4
5
10 rows selected.

How to select the max rowid from a subquery with group by

Hi Gurus,
Kindly help how to fix the following query because I'm getting Oracle error:ORA-01446.
select * from edy_raw_data a
where rowid in ( select max(rowid) from(
select email,max(date_updated) from edy_raw_data b
where b.email=a.email
group by email ))
The query select the max rowid from a sub query with group by.
Thanks in Advance.
Benjie

Why do you need to compare with rowid?
Wouldn't this suffice?
select * from edy_raw_data a
where (email,date_updated) = (select email, max(date_updated) from edy_raw_data b
where b.email=a.email
group by b.email ))* Note: untested

Select the max record on date, but not today

Hi all,
I have this table
Access
codi_uten number(9)
data_acce DATE
and for
select data_acce from Access
the codi_uten=3041
order by data_acce;
this is the result
DATA_ACCE

09-NOV-07
09-NOV-07
16-NOV-07
23-NOV-07
23-NOV-07
20-DIC-07
20-DIC-07
Where 20-Dic-07 is today ;)
I need a statment that can give me only the last data value (in this format dd/mm/yyyy) but it cannot consider today.
It's possible without use the RowId?
Thank's
Paolo from Madrid

No, you don't need rowids.
Creating an example table:
create table t
( id number primary key,
day date);
insert into t values(1, sysdate);
insert into t values(2, sysdate-1);
insert into t values(3, sysdate-2);
insert into t values(4, sysdate-3);Looking all rows:
select * from t

where day = (select max(day)

Can you select the max of a group by and mach it to another table?

I can't get my little head around this one. I have 2 tables
table 1:
T1ID col1 col2 col3
1 a t e
2 g y a
3 h r p
4 f u w
and table 2 that has many entries from table 1
Table 2:
T1ID ID col1
1 3 Y
1 2 M
1 1 H
3 2 W
3 1 E
I want the contents of table 1 with the value of col1 from table 2 where the ID is the highest?
so returning table 3:
ID col1 col2 col3 col1_from_table_3
1 a t e Y
2 g y a
3 h r p W
4 f u w
is this easy to do with a select statment?
Thanks for all of you help(in advance)

Compare Dates and select the max date ?

Hello,
I am trying to write a script and will compare the dates in " eff_startdt" and give me the lastest date at the outcome.
I have data that some service locations have more than one contract date and I need to get the latest dated conract dates to work on the data but I tried many things I am always getting errors. When I run the script below I get " missing expression" error. I dont' see anything missing.
also somehow Max() is keep giving me errors when I do something like [ ON service_locs = vmeterid WHERE SERVICE_LOCS = SERVICE_LOCS AND EFF_STARTDT = MAX(EFF_STARTDT) ]
Can someone pls give me advice on this. Thanks
SELECT DISTINCT Broker, customer_name, service_locs, fee_kwh, qtr_monthly, eff_startdt, eff_enddt
FROM VMETER
INNER JOIN BROKER_DATA
ON service_locs = vmeterid WHERE SERVICE_LOCS = SERVICE_LOCS AND (SELECT MAX(EFF_STARTDT) FROM VMETER)

Hi,
I will try to explain on my example. I have got a table:
DESC SOLD_ITEMS;

COMP_ID                                            NUMBERI have insert example data into my table:
select component, subcomponent, sale_date,comp_id
2 from sold_items;
COMPONENT       SUBCOMPONENT    SALE_DAT    COMP_ID
graph           bar             06/04/03          1
graph           bar             06/04/01          2

graph           bar             06/05/02          9
As you can see there are a few components and subcomponents duplicated with different date and comp_id value.
I want to get component and subcomponent combination with latest date.
SELECT COMPONENT, SUBCOMPONENT, MAX(SALE_DATE)
2 FROM SOLD_ITEMS
3* GROUP BY COMPONENT, SUBCOMPONENT;
Efect:
COMPONENT       SUBCOMPONENT    MAX(SALE
graph           bar             06/05/02
search          user search     06/04/02
search          product search 06/03/20
For your purpose I will do it using join and subquery. Maybe it will help you resolve your problem:
SELECT COMPONENT, SUBCOMPONENT, SALE_DATE, RANK
2 FROM (SELECT T1.COMPONENT, T1.SUBCOMPONENT, T2.SALE_DATE,
3          ROW_NUMBER() OVER (PARTITION BY T1.COMPONENT, T2.SUBCOMPONENT ORDER BY T2.SALE_DATE DESC) AS ROW
4          FROM SOLD_ITEMS T1, SOLD_ITEMS T2
5          WHERE T1.COMP_ID = T2.COMP_ID)
6* WHERE ROW = 1;
I joined the same table but it act as two different tables inside subquery. It will group values (partition by statement) and order result descending using t2.sale_date column. As you can see columns are returned from both tables. If you would like to add some conditions, you can do it after WHERE ROW=1 code.
Results:
COMPONENT       SUBCOMPONENT    SALE_DAT       RANK
graph           bar             06/05/02          1
search          product search 06/03/20          1
search          user search     06/04/02          1Hope this help you

Need to select the max record in a report

Dear All,
I have a certain report which displays the employee records along with their 'empids' and their 'beginning date'. For each 'empid', there are more than one records and hence more than one 'beginning date'. I need to select that record which contains the maximum 'beginning date'. How can this be possible in the reporting level without doing any coding in update rules or writing any exit ?
Regards,
Srinivas

Hi,
I think it is not possible because i am having doubt how the for each employ id how it will be different joining dates,i think for each employ having differeent joining dates ,if u want to see maximum number of employs in which in company then we can go for the only option non cumulative kf with maximum value with ur joining date as the reference.but it report level if it is keyfigure we can have options of maximum and minimum and like that we can do but in case of characterstic like employnumber and joiningdate both are characterstics.
Thanks

Select first rows with rowno

Problem: I search for 20 companies with highest turnover in a table. Its a dynamic SQL (created at runtime), I can not use a hard coded fetch of 20 rows.
(Example is a simple table with companyID, turnover and a key)
I read in documentation, that first rowno is applied, then the order (to be fast and not access the whole big table). Ok.
Oracle goes same way, this is the work around:
SELECT * FROM (SELECT t1.Firmid_i AS t1_Firmid_i, SUM( t1.Amount_dc ) AS t1_Amount_dc FROM DEMO.turnover t1 GROUP BY t1.Firmid_i, t1.Productid_i ORDER BY 2 desc ) WHERE rownum <= 20
I try this on a MaxDb :
SELECT * FROM (SELECT t1.Firmid_i, MAX( t1.Amount_dc ) FROM DEMO.turnover t1 GROUP BY t1.Firmid_i ORDER BY 2 asc) WHERE rowno <= 20
-> an error occur (General error;-5016 POS(103) Missing delimiter: ), the order in the inner sql is not allowed
I can change the statement:
SELECT * FROM (SELECT t1.Firmid_i, MAX( t1.Amount_dc ) FROM DEMO.turnover t1 GROUP BY t1.Firmid_i) WHERE rowno <= 20 ORDER BY 2 asc
Now I got 20 row (20 rows sorted), but not the results I need (sort is used to late).
Does anyone knows a workaroud?
TIA
Christian

Hello Christian,
Unfortunately, MaxDB does not support the ORDER BY/GROUP BY condition in sub-selects to achieve such a result set limitation, nor does it support a kind of LIMIT statement
as MS-SQL does.
Anyway, to give the correct results, the query will anyway
create the complete result set, to apply the correct sorting (as the rows can only be sorted when for all rows the values are known).
There is unfortunately no way to formulate such a query
in a single SQL statement, and so you can only
fetch as much rows you need, and discard the rest,
which you said is not possible for you.
Sorry

How to select one row with such sql

hi , everyone
I got a headache about this sql:
select * from E_VPN_pbxlink where ((SPILOTNUM ='1234' ) or (SPILOTNUM ='123')) order by SPILOTNUM desc ;
it retruns 2 records.
I need to get the record with SPILOTNUM ='1234' , how can I reform this sql
tks

Hi,
I think I see:
You want the longest spilotnum that starts with the same charachters as the parameter.
You can do a Top-N Query like this:
WITH got_rnum     AS
     select e.*
     ,     RANK () OVER (ORDER BY LENGTH (spilotnum DESC)     AS rnum
     from      E_VPN_pbxlink
     where      '123456'     LIKE SPILOTNUM || '%'
SELECT     *     -- or list all columns except rnum
FROM     got_rnum
WHERE     rnum     = 1
;There is a slightly simplerr way, using the ROWNUM pseudo-column, but its only slightly easier, and it won't help if, say, you want to pass two or more targets such as '123456' in the same query.

by default the value of the timeout is zero (0). it has no timeout for my understanding.
now i'm trying to find workaround.
i'll create 2 soa composite. 1 for get 500rows of data every time invoked. and 1 to loop to call the 1st composite.
this one work but have a intermittent error.
1st issue is i have to allocate a lot of connection pool to handle lots of db connection based on the db row data.
2nd issue i can't trace the xml in SOA EM composite request.
is the only way is to let the copy data from 1 database to another database handled by the DB ? cannot utilize the soa ?

How to select rows with Empty Column Entry

I am trying to select all rows with an empty column
select row1 from table where row2=' ';
Any suggestions. I tried a space and no space in between the ''.

An (theoretical) argument could be made that an empty string is not NULL (uknown), however Oracle's SQL and PL/SQL engines make no such distinction for VARCHAR2 and CHAR data types. As stated, you must use NULL as the comparison.

I want the max date but only look at rows with a certain category value.

I want a way to get the max date but only look at rows with a certain category value - ignoring the other rows. My detail table contains expenditures including date (col A) and category (col D) the number of rows will increase with expenditures over time. My summary table will have a cell for each category and display the last expense date for that category using a functionality that I must ask of you, dear community.
I am using the latest numbers on an iPad (4) with IOS6.
Secondarily, I would like to add another cell in the summery table with the value (col E) of the last expense for each category.
Thank you,
Warren

...later...
With the addition of an auxiliary column to the Main table, a second header row to the Most recent table, and a minor modification to the formula on the second table, the tables can handle a range of dates set by entering the first and last date into A1 abd B1 respectively of the summary table, Most recent.
Note that the selected range, shown with a green background in the auxiliary column, does not contain any category B expenses. Using LOOKUP, this would result in a repeat of the January 6 expense bering listed in this row. Switching to VLOOKUP, which can be set to require an exact match, allows the result shown—if there are no expenses in a given category, the formula returns "none" (or whatever message you substitute for "none" in the formula in that column).
Formulas:
Main::A2: =IF(OR(B<Most recent :: $A$1,B>Most recent :: $B$1),"x"&E,E)
Fill down to the end of column A.
This column must be located on the left side of the table (ie. must be column A), but may be hidden.
Most recent::A2: =IFERROR(VLOOKUP($D,Main :: $A:$D,COLUMN()+1,FALSE),"none")
"FALSE" will display as "Exact match" in Numbers's formula editor.
Fill down to the end of the table and right to column C.

Barry
