Return one row

This is part of SQL query in FROM clause:
select id, t, phase, time from measurement where phase=1 where id='1234'
This query can return more than one raw, but I need the only one, the latest one
I tried a lot of different stuff but no success!
Thanks

Gee, not sure if I got you right, but are you really sure that you need to do five (!) outer joins to your METNET table? Dont forget, each join, be it NESTED LOOPS, HASH or MERGE, requires extra CPU and I/O resources
Consider this query as a possible alternative:
SELECT tmh.heatid,
       decode(tempcb.phase_id, 1, tempcb.t) cb,
       decode(tempcb.phase_id, 2, tempcb.t) cb1,
       decode(tempcb.phase_id, 3, tempcb.t) blow1,
       decode(tempcb.phase_id, 4, tempcb.t) blow2,
       decode(tempcb.phase_id, 5, tempcb.t) blow3
FROM heat_melt_proces_data hmpd,
       tmelted_heats tmh,
       (select t, sarza, phase_id
          from metnet
         where phase_id BETWEEN 1 AND 5) tempcb
WHERE hmpd.heatid=tmh.heatid
   and tempcb.sarza (+) = tmh.heatid
   and (to_char(hmpd.convertertappingendtime , 'YYYY-MM-DD HH24:MI') between '2006-06-10 22:30:01' and '2006-06-12 06:30:00')
order by tmh.heatid, hmpd.convertertappingendtime;And if I got you right regarding your TRANSFERTIME column, this is what you are looking for:
SELECT tmh.heatid,
       decode(tempcb.phase_id, 1, tempcb.t) cb,
       decode(tempcb.phase_id, 2, tempcb.t) cb1,
       decode(tempcb.phase_id, 3, tempcb.t) blow1,
       decode(tempcb.phase_id, 4, tempcb.t) blow2,
       decode(tempcb.phase_id, 5, tempcb.t) blow3
FROM heat_melt_proces_data hmpd,
       tmelted_heats tmh,
       (select * from
               (select t, sarza, phase_id,
                       row_number() over
                         (partition by sarza, phase_id order by transfertime desc) rn
                  from metnet
                 where phase_id BETWEEN 1 AND 5)
          where rn = 1) tempcb
WHERE hmpd.heatid=tmh.heatid
   and tempcb.sarza (+) = tmh.heatid
   and (to_char(hmpd.convertertappingendtime , 'YYYY-MM-DD HH24:MI') between '2006-06-10 22:30:01' and '2006-06-12 06:30:00')
order by tmh.heatid, hmpd.convertertappingendtime;
Tip: converting DATEs into VARCHARs and using BETWEEN <varchar-const> AND <varchar-const> is generally an ouch-ouch approach.

How just return one row of a one to many join..

So I have a one to many join where the SMOPERATOR table has data I need however it has a couple of rows that match the JOIN condition in there. I just need to return one row. I think this can be accomplished with a subquery in the join however have not been able to come up with the right syntax to do so.
So:
SELECT "NUMBER" as danumber,
NAME,
SMINCREQ.ASSIGNMENT,
SMOPERATOR.PRIMARY_ASSIGNMENT_GROUP,
SMOPERATOR.WDMANAGERNAME,
SMINCREQ.owner_manager_name,
SMINCREQ.subcategory, TO_DATE('01-'||TO_CHAR(open_time,'MM-YYYY'),'DD-MM-YYYY')MONTHSORT,
(CASE WHEN bc_request='f' THEN 'IAIO'
WHEN (bc_request='t' and substr(assignment,1,3)<>'MTS') THEN 'RARO'
WHEN (bc_request='t' and substr(assignment,1,3)='MTS') THEN 'M'
ELSE 'U' end) as type
from SMINCREQ
left outer join SMOPERATOR on SMINCREQ.assignment=SMOPERATOR.primary_assignment_group
WHERE SMINCREQ.owner_manager_name=:P170_SELECTION and SMOPERATOR.wdmanagername=:P170_SELECTION
AND open_time BETWEEN to_date(:P170_SDATEB,'DD-MON-YYYY') AND to_date(:P170_EDATEB,'DD-MON-YYYY')
AND
(bc_request='f' and subcategory='ACTIVATION' and related_record<>'t')
OR
(bc_request='f' and subcategory<>'ACTIVATION')
OR
(bc_request='t' and substr(assignment,1,3)<>'MTS')
order by OPEN_TIMe

Hi,
This sounds like a Top-N Query , where you pick N items (N=1 in this case) off the top of an orderded list. I think you want a separate ordered list for each assignment; the analytic ROW_NUMBER function does that easily.
Since you didn't post CREATE TABLE and INSERT statements for your sample data, I'll use tables from the scott schema to show how this is done.
Say you have a query like this:
SELECT       d.dname
,       e.empno, e.ename, e.job, e.sal
FROM       scott.dept d
JOIN       scott.emp   e ON   d.deptno = e.deptno
ORDER BY dname
;which produces this output:
DNAME               EMPNO ENAME      JOB              SAL

SALES                7654 MARTIN     SALESMAN        1250Now say you want to change the query so that it only returns one row per department, like this:
DNAME               EMPNO ENAME      JOB              SAL
ACCOUNTING           7782 CLARK      MANAGER         2450

SALES                7499 ALLEN      SALESMAN        1600where the empno, ename, job and sal columns on each row of output are all taken from the same row of scott.emp, though it doesn't really matter which row that is.
One way to do it is to use the analytic ROW_NUMBER function to assign a sequence of unique numbers (1, 2, 3, ...) to all the rows in each department. Since each sequence startw with 1, and the numbers are unique within a department, there will be exactly one row per departement that was assigned the numebr 1, and we''ll display that row.
Here's how to code that:
WITH     got_r_num     AS
     SELECT     d.dname
     ,     e.empno, e.ename, e.job, e.sal
     ,     ROW_NUMBER () OVER ( PARTITION BY d.dname
                               ORDER BY         e.ename
                       )         AS r_num
     FROM     scott.dept d
     JOIN     scott.emp   e ON   d.deptno = e.deptno
SELECT       dname
,       empno, ename, job, sal
FROM       got_r_num
WHERE       r_num     = 1
ORDER BY dname
;Notice that he sub-query got_r_num is almost the same as the original query; only it has one additional column, r_num, in the SELECT clause, and the sub-qeury does not have an ORDER BY clause. (Sub-queries almost never have an ORDER BY clause.)
The ROW_NUMBER function must have an ORDER BY clause. In this example, I used "ORDER BY ename", meaning that, within each department, the row with the first ename (in sort order) will get r_num=1. You can use any column, or expression, or expressions in the ORDER BY clause. You muight as well use something consistent and predictable, like ename, but if you really wanted arbitrary numbering you could use a constant in the analytic ORDER BY clause, e.g. "ORDER BY NULL".

Returning one row in a view(only)

Is there any function that I can use to return just one row from a query?

I´m using a Oracle8

Try using "where ROWNUM = 1" for the first row returned by the select

Returning one row per group

I apologize if this is a duplicate of some other post, but I'm not finding this exact scenario.
Assume that I have a table that looks like this:
select * from PROD_TABLE
PROD DESCRIPTION
1234 CANDLES
1234 CANDLE
1235 BRAKE PADS
1235 BRAKE PAD
(Yes, I know, I know, but it's for a POC, so dirty data will be cleaned up later.)
What I'd like to do is create a select statement that returns two rows from this table, one row for Prod 1234, one row for Prod 1235, and I DON'T CARE which description is returned for the corresponding Prod. For the POC, it's just not important which one is returned.
How can I craft the select statement?

try this
SQL> with t as (select 1234 prod, 'CANDLES' dec from dual union all
2 select 1234 ,'CANDLE' dec from dual union all
3 select 1235 ,'BRAKE PADS' dec from dual union all
4 select 1235 ,'BRAKE PAD' dec from dual)
5 SELECT prod, DEC
6    FROM ( SELECT a.*
7                , ROW_NUMBER ( ) OVER ( PARTITION BY prod ORDER BY prod ) rn
8            FROM t a )
9   WHERE rn = 1

Result Set only returning one row...

When I run the following query in my program, I only get one row.
SELECT * FROM (SELECT * FROM ul_common_log_event WHERE application_name = 'Configuration' ORDER BY cle_id DESC) WHERE ROWNUM <= 500;
However when I run it in TOAD, I get all the rows I am looking for.
Here's my java
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query);
My record set only contain one row. I am using Oracle 9 OCI driver BTW.
Any ideas? Thanks!

Good thinking. That was the first thing I tried. That was not the problem. It turns out that I was stomping my rs object in another method. Problem resolved!
Thanks for the reply!

Return one row (DISTINCT) in a query BEX

Hi guru, i have this scenary:
one infoset on ods with timestamp field and material code
In the ODS i found many occurrence with same material code, but with many timestamp loading, es:
material        timestamp
00AAA          20070301
00AAA          20070201
00BBB          20070101
in my query i want this result:
00AAA          20070301
00BBB          20070101
Can i have help for this troble ?
Thank's a lot.

Hi,
I think is not possible to do this in the query. I think you have to filter the ODS data. I would build another DSO and would filter the data in the transformation. If you buid another DSO you can include the master data and you wouldn't need the infoset.

Report Queries - Multiple Source queries - One source returns & one doesn't

Hi Folks.
Odd one here.
I have a report query entry in the Shared Components of the APEX UI.
Within the Query are two source queries.
Both return unique column names.
Both use the same bind variable.
When generating a PDF using the call to the report, the data from one query is being returned and the data from another is not.
I have generated a sample XML file from APEX which is populated with data for both queries.
If I import this into MS-Word using the BIP plugin and generate a preview all is fine. All fields using data from both source queries are populated.
When generated via a regular call within APEX it simply does not work. I only get the data from one query.
Does anyone have any suggestions?
Anyone had a similar thing?
Any comments/suggestions welcome.
Many thanks
Dogfighter.

Hi Marc
Does this make sense to you?
I have now set up a simple report query and report layout.
The record ID is hard coded into the query so that it only returns one row.
I am using an RTF based template.
If I navigate to Shared Components > Report Queries > Edit Report Query and then press the 'Test Report' button it runs perfectly.
If I copy the 'Print URL:' value from this page and use it as the URL target on any page in the app. it also works perfectly.
If I try and execute the following...
update invoice_summary
set invoice_pdf = APEX_UTIL.GET_PRINT_DOCUMENT (127, -- App ID
'TEST_INVOICE', -- query name
'TEST_INVOICE') -- layout name
where invoice_summary_gsm_id = a.INVOICE_ID;
I get the pdf saved to the BLOB column with the field labels in place but no data.
Three ways of running the report.
Two of them work perfectly but the one I want (generate direct into BLOB column) does not. Why would the exact same report query & report layout work with the other two methods but not the GET_PRINT_DOCUMENT route?
It's not as if the pdf does not get into the BLOB column, it does, but it only has the labels and no values.
Any ideas?
Simon.
PS. I only have one report query and one report layout set up so as to avoid confusion. Both with the same name.

Repaint One Row at a Time

Hi,
I have a graphical program that repaints every 2000 ms. I want to call another program that queries the Oracle dbase and returns one row at a time, so that in the graphical program, I see the value of the next row every 2000 ms. Any ideas on how I'd do this?
I have the basics on resultsets and statements and using while(rs.next()), etc.. Thanks. Chris.

Insert "Thread.sleep(2000);" at places where you want your program to wait for 2000 milliseconds.

Return first row entered based on date column

I'm trying to select the first entered row in a table, as judged by the datetime column. If more than one row has the same date and time, then only one row should be returned (any row having that datetime is fine). Some processing will occur on that row and then it will be deleted. The select statement is used thereafter to select the next (first) entered row in the table, etc. This way, the rows are processed first-in first-out (FIFO) style. Here's my example table:
create table my_table
datetime date,
firstname varchar2(50)
insert into my_table(datetime, firstname) values(to_date('2012-04-02 11:00:00', 'YYYY-MM-DD HH24:MI:SS'),'ken');
insert into my_table(datetime, firstname) values(to_date('2012-04-02 11:00:00', 'YYYY-MM-DD HH24:MI:SS'),'john');
insert into my_table(datetime, firstname) values(to_date('2012-04-02 11:00:00', 'YYYY-MM-DD HH24:MI:SS'),'sue');
commit;
Here's my example select statement, which returns simply one row of the above, since all are the same date and time:
SELECT *
FROM my_table
WHERE datetime = ( select min(datetime) from my_table )
AND rownum = 1;
My question is, if I use the following
SELECT *
FROM my_table
WHERE datetime = ( select min(datetime) from my_table );
It returns all 3 rows:
DATETIME FIRSTNAME
02-APR-12 11:00:00 ken
02-APR-12 11:00:00 john
02-APR-12 11:00:00 sue
So, wouldn't setting rownum = 2 return john, and rownum = 3 return sue? For example,
SELECT *
FROM my_table
WHERE datetime = ( select min(datetime) from my_table )
AND rownum = 2;
return no rows. I just want to make sure I'm understanding how the select statement above works. It seems to work fine for returning one row having the minimum date and time. If this is always the case, then everything is fine. But I wouldn't have expected it not to return one of the other rows when rownum is 2 or 3, which makes me question why? Maybe I can learn something here. Any comments much appreciated.

If the row is not chosen for any reason, the same ROWNUM will be reused with the next row fetched. ROWNUM=2 will not be assigned until a row with ROWNUM=1 has been included in hte result set.
So, in your example:
SELECT *
FROM    my_table
WHERE   datetime = ( select min(datetime) from my_table )
AND     rownum = 2;Say the first row that happens to be fetched has firstname='ken'. It is assigned ROWNUM=1, and fails the WHERE clause condition "WHERE rownum = 2".
Say the next row fetched has firstname='john'. ROWNUM=1 hasn't been used yet, so this row is also assigned ROWNUM=1, and it fails the WHERE clause for the same reason. Likewise with the next row; it also is assigned ROWNUM=1, and it also fails.
When using ROWNUM in a WHERE clause, you almost always want to say "ROWNUM = 1" or "ROWNUM <= n".
You could also use the analytic ROW_NUMBER function:
WITH     got_r_num     AS
     SELECT     datetime, firstname
     ,     ROW_NUMBER () OVER (ORDER BY datetime)     AS r_num
     FROM     my_table
SELECT     datetime, firstname
FROM     got_r_num
WHERE     r_num     = 1
;Here, all values of r_num are available, so it would make sense to say things like "WHERE r_num = 2" or "WHERE r_num >= 2".

[CLOSED] MAX returning two rows

Hi all,
I need to write a query that return 1 row.
If 'part 1' returns a value, the query needs to return null. If 'part 1' returns multiple values for latest_date, I need to return the latest of the dates.
Currently, this is the query I have. However this query returns more than 1 row.
Anny pointers are appreciated. Thanks

Hi,
max funtion never returns two rows :-)
If 'part 1' returns a value, the query needs to
return null. If 'part 1' returns multiple values for
latest_date, I need to return the latest of the
dates.It can't dual always return 1 row.
So, why do you need part 2?

This will make your query return one row, but that's probably not what you want:

Returning one result

Ok. So, here is my issue, I am running a query on an oracle 10 database, through pl/sql developer. The result set returns something like this:
ID Code
A 001-012
A 001-021
A 001-032
A 001-043
B 001-023
B 001-054
B 001-003
B 001-002
B 001-007
I would like it to return this
ID Code
A 001-012
B 001-054
The "Code"(ex. 001-043) does not matter, only has to return one for each ID (ex. A), but has to return every unique ID. The problem with it is that there is no one common "Code" for each "ID".
I am sure this makes absolutely no sense...but if it does, and someone out there has any suggestions..would greatly appreciate it :)

Nicolas.That's the thing, it doesn't matter which row it picks, as long as it only returns one row for each ID. That's why I am struggling I think
Edited by: Shamrock on Jun 16, 2010 7:10 AMIf it doesn't matter which "code" it returns with the distinct "id", why select the "code" in the first place. You just said, in effect, it is meaningless.
just SELECT DISTINCT ID ....

Report Builder 2.0 returning duplicate rows in query designer

Hi,
I have a query running off a model, when I explore the data in the model and in a standard sql table it returns one row for each record, which include a unique id for each which is correct.
When I go into report builder query designer, it shows duplicate rows for each record. I have removed and added fields to try and pin point why and the only reason i can come up with is that it runs fine until I add in a field thats varchar(255) or
varchar(max). This is when it starts to duplicate the records.
Can anyone tell me why it does this or point me in the direction of how to stop this. I can't edit the query in text to add DISTINCT so thats not an option.
Many thanks,
JJSJ

OK - I have found a partial answer.   By Googling Report Builder and VARCHAR, I found another post which reported problems with the semantic query builder when the underlying table/view was returning columns of type VARCHAR(MAX).
On looking at the length setting for the data column in the DSV, this reported a length of 2,147,483,647 for this field.   This is very odd because on querying the underlying table the largest length that I can find for this column is 191,086
(which is far larger than I would have expected - I am investigating this separately).
However, why should the Report Model think that this field contains such a large value?
Anyway, the other post that I found reported that they had solved their problem by converting the field to a VARCHAR (255).    I tried this (by casting the column in my View to VARCHAR(255)) and this resolved the problem
- no more duplicate rows when adding this field to the query!!!
I also tried CASTING to TEXT and to VARCHAR(8000). The former did not resolve the problem; the latter did.
So I have a workaround but I don't understand why.
Can anybody explain why having a VARCHAR(max) column in my entity causes duplicate rows.
I suspect it is to do with the fact that for some reason the Report Model seems to think that there is an exceptionally long text string stored in this column in one of the rows but that again is a puzzle.
Thanks

Hi,
The cursor has a different parameter? Maybe the query is not exactly the same. Could you check this?
This is your query (formatted):
SELECT DISTINCT PSE.PARENT_POSITION_ID,
                (SELECT DISTINCT PPD1.SEGMENT2
                   FROM PER_POSITION_DEFINITIONS   PPD1,
                        HR_ALL_POSITIONS_F         HAPF2,
                        PER_POS_STRUCTURE_ELEMENTS PSE2
                  WHERE TRUNC(SYSDATE) BETWEEN HAPF2.EFFECTIVE_START_DATE AND
                        HAPF2.EFFECTIVE_END_DATE
                    AND PPD1.POSITION_DEFINITION_ID = HAPF2.POSITION_DEFINITION_ID
                    AND HAPF2.POSITION_ID = PSE2.PARENT_POSITION_ID
                    AND PSE2.PARENT_POSITION_ID = PSE.PARENT_POSITION_ID
                    AND ROWNUM = 1) SEGMENT2,
                (SELECT DISTINCT PAPF1.FIRST_NAME || ' ' || PAPF1.LAST_NAME CHIEF_NAME
                   FROM PER_ALL_PEOPLE_F      PAPF1,
                        PER_ALL_ASSIGNMENTS_F PAAF1
                  WHERE TRUNC(SYSDATE) BETWEEN PAPF1.EFFECTIVE_START_DATE AND
                        PAPF1.EFFECTIVE_END_DATE
                    AND TRUNC(SYSDATE) BETWEEN PAAF1.EFFECTIVE_START_DATE AND
                        PAAF1.EFFECTIVE_END_DATE
                    AND PAAF1.POSITION_ID = PSE.PARENT_POSITION_ID
                    AND PAPF1.PERSON_ID = PAAF1.PERSON_ID
                    AND ROWNUM = 1) CHIEF_NAME
FROM PER_POS_STRUCTURE_ELEMENTS PSE,
       HR_ALL_POSITIONS_F         HAPF,
       PER_POSITION_DEFINITIONS   PPD
WHERE PSE.SUBORDINATE_POSITION_ID = 52744
   AND TRUNC(SYSDATE) BETWEEN HAPF.EFFECTIVE_START_DATE AND HAPF.EFFECTIVE_END_DATE
   AND HAPF.POSITION_ID = PSE.SUBORDINATE_POSITION_ID
   AND HAPF.POSITION_DEFINITION_ID = PPD.POSITION_DEFINITION_ID;Tips: To put formatted code you must use {noformat}{noformat} tags, start tag and end tag are the same,you don't need to put '/' in the close tag.

One to many to return only one row

hi guys,
i have an urgent problem here. i have a sql statement like below;
SELECT ALM_SWAP2_REP.M_TP_RTMFRP0, ALM_SWAP2_REP.M_TP_RTMFRP1,
ALM_SWAP2_REP.M_TP_RTMFRF0, ALM_SWAP2_REP.M_TP_RTMFRF1,
To_Char(TRN_HDR_DBF.M_OPT_FLWFST,'YYYYMMDD') AS VALDATE, ALM_SWAP2_REP.M_TP_RTFXC02,
ALM_SWAP2_REP.M_TP_RTFXC12, TRN_HDR_DBF.M_BRW_NOMU1, TRN_HDR_DBF.M_BRW_NOMU2,
ALM_SWAP2_REP.M_TP_RTAMC02, ALM_SWAP2_REP.M_TP_RTAMC12,
(CASE WHEN PAY_FLOW_DBF.M_LEG = 0 AND '20100831' BETWEEN To_Char(PAY_FLOW_DBF.M_CALC_DATE0,'YYYYMMDD') AND To_Char(PAY_FLOW_DBF.M_CALC_DATE1,'YYYYMMDD') THEN To_Char(PAY_FLOW_DBF.M_CALC_DATE1,'YYYYMMDD') END) AS RCV_DATE,
(CASE WHEN PAY_FLOW_DBF.M_LEG = 1 AND '20100831' BETWEEN To_Char(PAY_FLOW_DBF.M_CALC_DATE0,'YYYYMMDD') AND To_Char(PAY_FLOW_DBF.M_CALC_DATE1,'YYYYMMDD') THEN To_Char(PAY_FLOW_DBF.M_CALC_DATE1,'YYYYMMDD') END) AS PAY_DATE
FROM ALM_SWAP2_REP, TRN_HDR_DBF, PAY_FLOW_DBF WHERE ALM_SWAP2_REP.M_REF_DATA = 456576
AND ALM_SWAP2_REP.M_NB = TRN_HDR_DBF.M_NB
AND ALM_SWAP2_REP.M_NB = PAY_FLOW_DBF.M_TRN_ID
AND ALM_SWAP2_REP.M_NB = 228128
AND '20100831' BETWEEN To_Char(PAY_FLOW_DBF.M_CALC_DATE0,'YYYYMMDD') AND To_Char(PAY_FLOW_DBF.M_CALC_DATE1,'YYYYMMDD')
ORDER BY ALM_SWAP2_REP.M_TRN_GRP, ALM_SWAP2_REP.M_NB
When I join few tables, the results are returned in two rows because I have two records that in table PAY_FLOW_DBF that matches one row in table ALM_SWAP2_REP. I need these two matches but I want it to be returned in only one row without using group by. Pls help me. Thankls
