Help in Join Select Query

Hi, Please help on the Select Join query. I want to compare code_stat_system1/code_stat_system2 and code_date_system1 /code_date_system2 column from table #system1 and #system2 but there is 2 rule to get correct row from table #system1 and #system2.
Rule 1: We need to get max(code_date_system1) record from #system1 for every code_system1 for compare.
Rule 1: We need to get max(code_date_system2) record from #system2 BUT BEFORE THE RECORD OF 'DKNOW' OF code_stat_system2 for every code_system2 for compare.
drop table #system1,#system2
create table #system1
(Code_system1 varchar(10),code_stat_system1 varchar(10),code_date_system1 datetime)

Need some help with the Select query.
I had created a Z table with the following fields :
ZADS :
MANDT
VKORG
ABGRU.
I had written a select query as below :
select single vkorg abgru from ZADS into it_rej.
IT_REJ is a Work area:
DATA : BEGIN OF IT_REJ,
        VKORG TYPE VBAK-VKORG,
        ABGRU TYPE VBAP-ABGRU,
       END OF IT_REJ.
This is causing performance issue. They are asking me to include the where condition for this select query.
What should be my select query here?
Please suggest....
Any suggestion will be apprecaiated!

Hello Everybody!
Thank you for all your response!
I had changes this work area into Internal table and changed the select query. PLease let me know if this causes any performance issues?

I had removed the select single and insted of using the Structure it_rej, I had changed it into Internal table

Earlier :
IT_REJ is a Work area:

Now :
DATA : BEGIN OF IT_REJ occurs 0,
VKORG TYPE VBAK-VKORG,
ABGRU TYPE VBAP-ABGRU,
END OF IT_REJ.
I guess this will fix the issue correct?
PLease suggest!

How to do outer join select query for an APEX report

Hello everyone,
I am Ann.
I have one select statement that calculate the statistics for one month(October 2012 in this example)
select ph.phase_number
, sum ( (case
WHEN ph.date_finished IS NULL OR ph.date_finished > last_day(TO_DATE('Oct 2012','MON YYYY'))
THEN last_day(TO_DATE('Oct 2012','MON YYYY'))
ELSE ph.date_finished
END )
- ph.date_started + 1) / count(def.def_id) as avg_days
from phase_membership ph
inner join court_engagement ce on ph.mpm_eng_id = ce.engagement_id
inner join defendant def on ce.defendant_id = def.def_id
where def.active = 1
and ph.date_started <= last_day(TO_DATE('Oct 2012','MON YYYY'))
and ph.active = 1
and UPPER(ce.court_name) LIKE '%'
group by rollup(phase_number)
Result is as below
Phase_Number     AVG_DAYS
Phase One     8.6666666666666667
Phase Two     14.6
Phase Three     12
     11.4615365
I have other select list mainly list the months between two date value.
select to_char(which_month, 'MON YYYY') as display_month
from (
select add_months(to_date('Aug 2012','MON YYYY'), rownum-1) which_month
from all_objects
where
rownum <= months_between(to_date('Oct 2012','MON YYYY'), add_months(to_date('Aug 2012','MON YYYY'), -1))
order by which_month )
Query result is as below
DISPLAY_MONTH
AUG 2012
SEP 2012
OCT 2012
Is there any way that I can join these two select statement above to generate a result like:
Month          Phase Number     Avg days
Aug 2012     Phase One     8.666
Sep 2012     Phase One     7.66
Oct 2012     Phase One     5.66
Aug 2012     Phase Two     8.666
Sep 2012     Phase Two     7.66
Oct 2012     Phase Two     5.66
Aug 2012     Phase Three     8.666
Sep 2012     Phase Three     7.66
Oct 2012     Phase Three     5.66
Or
Month          Phase Number     Avg days
Aug 2012     Phase One     8.666
Aug 2012     Phase Two     7.66
Aug 2012     Phase Three     5.66
Sep 2012     Phase One     8.666
Sep 2012     Phase Two     7.66
Sep 2012     Phase Three     5.66
Oct 2012     Phase One     8.666
Oct 2012     Phase Two     7.66
Oct 2012     Phase Three     5.66
And it can be order by either Phase Number or Month.
My other colleague suggest I should use an left outer join but after trying so many ways, I am still stuck.
One of the select I tried is
select a.display_month,b.* from (
select to_char(which_month, 'MON YYYY') as display_month
from (
select add_months(to_date('Aug 2012','MON YYYY'), rownum-1) which_month
from all_objects
where
rownum <= months_between(to_date('Oct 2012','MON YYYY'), add_months(to_date('Aug 2012','MON YYYY'), -1))
order by which_month )) a left outer join
( select to_char(ph.date_finished,'MON YYYY') as join_month, ph.phase_number
, sum ( (case
WHEN ph.date_finished IS NULL OR ph.date_finished > last_day(TO_DATE(a.display_month,'MON YYYY'))
THEN last_day(TO_DATE(a.display_month,'MON YYYY'))
ELSE ph.date_finished
END )
- ph.date_started + 1) / count(def.def_id) as avg_days
from phase_membership ph
inner join court_engagement ce on ph.mpm_eng_id = ce.engagement_id
inner join defendant def on ce.defendant_id = def.def_id
where def.active = 1
and ph.date_started <= last_day(TO_DATE(a.display_month,'MON YYYY'))
and ph.active = 1
and UPPER(ce.court_name) LIKE '%'
group by to_char(ph.date_finished,'MON YYYY') , rollup(phase_number)) b
on a.display_month = b.join_month
but then I get an error
SQL Error: ORA-00904: "A"."DISPLAY_MONTH": invalid identifier
I need to display a report on APEX with option for people to download at least CSV format.
I already have 1 inteactive report in the page, so don’t think can add another interactive report without using the iframe trick.
If any of you have any ideas, please help.
Thanks a lot.
Ann

First of all, a huge thanks for following this Frank.
I have just started working here, I think the Oracle version is 11g, but not sure.
To run Oracle APEX version 4, I think they must have at least 10g R2.
This report is a bit challenging for me.I has never worked with PARTITION before.
About the select query you suggested, I run , and it seems working fine, but if I try this,
it return error ORA-01843: not a valid month

The requirements are:
The user must be able to request the extract for one or more calendar months, e.g.
May 2013
May 2013 – Sep 2013.
The file must contain a separate row for each calendar month in the requested range. Each row must contain the statistics computed for that calendar month.
The file must also include a row of totals.
The user must be able to request the extract for either Waitakere or Auckland or Consolidated (both courts’ statistics accumulated).
Then the part that I am stuck is
For each monitoring phase:
Phase name (e.g. “Phase One”)
Avg_time_in_phase_all_particip
for each phase name,
Add up days in each “phase name” Monitoring Phase, calculated as:
If Monitoring Phase.Date Finished is NULL or > month end date,
+(*Month end date* Minus Monitoring Phase.Date Started Plus 1)+
Otherwise (phase is complete)
+(Monitoring Phase.Date Finished Minus Monitoring Phase.Date Started Plus 1.)+
Divide by the numbers of all participants who have engaged in “phase name”.
This is the words of the Business Analyst,
I try to do as required but still struggle to identify end_month for the above formula to display for the range of months.
Of course, I can write two nested cursor. The first one run the list of month, then for each month, run the parameterised report.
But I prefer if possible just use SQL statements, or at least a PL/SQL but return a query.
With this way, I can create an APEX report, and use their CSV Extract function.
Yes, you are right, court_name is one of the selection parameters.
And the statistics is not exactly for one month. It is kind of trying to identify all phases that are running through the specified month (even phase.date_started is before the month start).
This is the reason why I put the condition AND ph.date_started <= last_day(TO_DATE('Oct 2012','MON YYYY')) (otherwise I get negative avg_days)
User can choose either one court "AA" or "BB" or combined which is all figures.
Sorry for bombarding you a lot of information.
Thanks a lot, again.

Help reagrding the selection query

Hi All...
I have     VBELN
     LFART
     VKORG
     KUNNR
     ERDAT
     LFDAT
     VSTEL
     ROUTE in my selection-screen. All the fields are from LIKP.
Now I need to add one more field LAND1 from the table VBPA in the selection screen.
This is my logic to filter the previous requirement. Now how to validate the LAND1?
-> LIKP
select vbeln
          into table i_likp
          from likp
          where vbeln in s_vbeln
            and lfart in s_lfart
            and vkorg in s_vkorg
            and kunnr in s_kunnr
            and erdat in s_erdat
            and lfdat in s_lfdat
            and vstel = p_vstel
            and route in s_route.
if sy-subrc = 0.
-> LIPS
    select vbeln posnr bwtar volum
            into table i_lips
            from lips
            for all entries in i_likp
            where vbeln = i_likp-vbeln.
Please help me in that. I will reward u with good points.

For LAND1 validation do as below.
AT SELECTION-SCREEN ON s_land1.
SELECT land1 FROM t005
                       into t005-land1
                       where land1 IN s_land1.
if sy-subrc NE 0.
message e000 WITH 'Enter valid Land value'.
endif.
For the query u can use join
select a~vbeln b~posnr b~bwtar b~volum
         from likp as a inner join lips as b
         on a~vbeln =b~vbeln
         into table i_tab
         where a~vbeln in s_vbeln

Help regarding a select Query

hi All,
I have one requirement.I wonder whether i can do it in a single SQL Statement or not.
I have tab1 with columns c1,c2,c3,c4,....,Logon_time
I have tab2 with columns C1,c2,c3,c4.....,Logoff_time
All the columns are same for two tables except that logon_time and logoff_time as mentioned above.
tab1 will have all the information of user who logon to database.
tab2 will have all the information of user who logoff from DB.
Now i i have to generate a report which shows all the user info and logon Duration.For that i can use logoff_time - logon_time.but the challenge here is logoff_time dont contain rows for the users who logon to database byt yet to logoff.
So for them logoff_time-logon_time showing -ve Duration.
So I want Duration as logoff_time-logon_time for all the rows.But for those users who yet to logoff i want duration as "YET to Logoff"
Is this possible with single Select Query.
Thanks
Pramod

Hi, Pramod,
You need to join tab_1 to tab_2. Since not every row in tab_1 will have a matching row in tab_2, make it an outer join.
How do you know which row in tab_1 matches which row in tab_2?
I assume there's some column (let's say c1) that identifies a user. A user can have several sessions going at the same time, however.
The following query matches the n-th logon_time in tab_1 with the n-th logoff_time in tab_2 for the same user:
WITH     numbered_tab_1     AS
     SELECT c1, c2, c3, c4, ..., logon_time
     ,     ROW_NUMBER () OVER ( PARTITION BY c1     -- or whatever identifies user
                               ORDER BY         logon_time
                       ) AS r_num
     FROM     tab_1
,     numbered_tab_2     AS
     SELECT c1, c2, c3, c4, ..., logon_time
     ,     ROW_NUMBER () OVER ( PARTITION BY c1     -- or whatever identifies user
                               ORDER BY         logoff_time
                       ) AS r_num
     FROM     tab_2
SELECT     t1.c1, t1.c2, t1.c3, t1.c4, ..., t1.logon_time     -- or whatever you want
,     t2.c1, t2.c2, t2.c3, t2.c4, ..., t2.logoff_time
,     NVL ( TO_CHAR (24 * (t2.logff_time - t1.logon_time))    -- duration in hours
         , 'Yet to Logoff'
         )         AS duration
FROM             numbered_tab_1     t1
LEFT OUTER JOIN     numbered_tab_2     t2     ON   t1.c1     = t2.c1
                                 AND t1.r_num = t2.r_num
;I can test this if you'll post some sample data and the results you want from that data.
The query above matches logons and logoffs only by user and time
For example, say I log on at 10:00.
At 10:45, I open another window and log on again, but log off at 10:50 after 5 minutes.
At 11:30 I log off the first session.
If you were interested in sessions that lasted over 1 hour, the query above would not be accurate. It would show one session starting at 10:00 and ending at 10:50, and another session starting at 10:45 and ending at 11:30. To know that the first session to end was the second sessiion in order of beginning, you would have to have another column, say a unique session id.
If you're only interested in the number of sessions, or the total time connected per user, then the query above will be good enough.

I need help with a SELECT query - help!

Hello, I need help with a select statement.
I have a table with 2 fields as shown below
Name | Type
John | 1
John | 2
John | 3
Paul | 1
Paul | 2
Paul | 3
Mark | 1
Mark | 2
I need a query that returns everything where the name has type 1 or 2 but not type 3. So in the example above the qery should bring back all the "Mark" records.
Thanks,
Ian

Or, if the types are sequential from 1 upwards you could simply do:-
SQL> create table t as
2 select 'John' as name, 1 as type from dual union
3 select 'John',2 from dual union
4 select 'John',3 from dual union
5 select 'Paul',1 from dual union
6 select 'Paul',2 from dual union
7 select 'Paul',3 from dual union
8 select 'Paul',4 from dual union
9 select 'Mark',1 from dual union
10 select 'Mark',2 from dual;
Table created.
SQL> select name
2 from t
3 group by name
4 having count(*) <= 2;
NAME
Mark
SQL>Or another alternative if they aren't sequential:
SQL> ed
Wrote file afiedt.buf
1 select name from (
2    select name, max(type) t
3    from t
4    group by name
5    )
6* where t < 3
SQL> /
NAME
Mark

Pls help me in select query......

My problem is...
I have to use a select query in such a manner that i can compare the last 8 characters or ignore the first one...

Hi Aarif,
Try this :
parameters :
p_field1(30) type c.
Data :
w_string(8) type c,
w_firstchar type c,
t_itab ......,
fs_itab like line of itab.
w_string = p_field1+22(8)      " passing last 8 chars into w_string
w_firstchar = p_field1+0(1).
select *
   from DataTab Name
   into table IntTab Name
where <field name> eq w_string
      or <field name> ne w_firstchar.
If you are accepting the value from user then first pass the last 8 characters into w_string and in your select query get the fields where the value is equal to w_string. And pass the first character into another field and to ignore write NE W_FIRSTCHAR.
There can be other methods also. This is one of the ways.
Regards,
Swapna.

Inner Join Select query

hello all,
Below is a inner join query
    SELECT aebeln aebelp apackno bzekkn b~ps_psp_pnr
                 FROM ( ( ekpo AS a INNER JOIN ekkn AS b
                          ON aebeln = bebeln
                          AND aebelp = bebelp )
                         INNER JOIN prps AS c
                          ON bps_psp_pnr = cpspnr )
                 INTO TABLE t_wbspo
                  WHERE a~ebeln IN s_ebeln
                   AND c~psphi IN s_psphi
                   AND stufe = c_task.
I want to modify this select and put one more join on ekkn-aufnr
and aufk-afunr .
Now for this i write the below code
SELECT aebeln aebelp apackno bzekkn bps_psp_pnr baufnr
           FROM ( ( ( ekpo AS a INNER JOIN ekkn AS b
                    ON aebeln = bebeln
                    AND aebelp = bebelp )
                   INNER JOIN prps AS c
                    ON bps_psp_pnr = cpspnr )
                    INNER JOIN aufk AS d
                    ON baufnr = daufnr )
           INTO TABLE t_wbspo
            WHERE a~ebeln IN s_ebeln
             AND c~psphi IN s_psphi
             AND d~aufnr IN s_aufnr
    AND stufe = c_task.
By the above way does it puts a join on ekkn-aufnr and aufk-aufnr ?
Is the above way the right way to do it ?
Please confirm
regards

Need help for SQL SELECT query to fetch XML records from Oracle tables having CLOB field

Hello,
I have a scenario wherein i need to fetch records from several oracle tables having CLOB fields(which is holding XML) and then merge them logically to form a hierarchy XML. All these tables are related with PK-FK relationship. This XML hierarchy is having 'OP' as top-most root node and ‘DE’ as it’s bottom-most node with One-To-Many relationship. Hence, Each OP can have multiple GM, Each GM can have multiple DM and so on.
Table structures are mentioned below:
OP:
Name                             Null                    Type
OP_NBR                    NOT NULL      NUMBER(4)    (Primary Key)
OP_DESC                                        VARCHAR2(50)
OP_PAYLOD_XML                           CLOB

Appreciate your help in this regard!

Hi,
A few questions :
How's your first query supposed to give you an XML output like you show ?
Is there something you're not telling us?
What's the content of, for example, <OP_PAYLOD_XML1> ?
I don't think it's a good idea to embed the node level in the tag name, it would make much sense to expose that as an attribute.
What's the db version BTW?

I want the o/p to be like case 1 with the corrleator id . plz help me to get the o/p.
Case 1: select b.TransactionName, max(to_char(b.duration, 'mm/dd/yyyy hh24:mi:ss.ff')) as average from trandetails a,subtrandetails b where a.CORRELATORID=b.PCORRELATORID and b.PCORRELATORID='11' group by b.transactionname

in the above output i should have only record(max time) for FINT3.

Help with nested select query

Here is my code , i dont have any experience with writing the nested sql , i got the below code , which needs to be modified adding a case statement which will show util_rate for 2 conditions
1. given in where condition ( to_char(time_stamp,'HH24') >= '09' and to_char(time_stamp,'HH24') <= '19')
2.Apposite to the condition above (to_char(time_stamp,'HH24') < '09'and to_char(time_stamp,'HH24') > '19')
could anybody please help me in adding the 2nd condition to the below query , please share any documentation you have for learning how to write nested sql,
Thank you
select device,time_stamp,
sum(ActiveHRS)/sum(AvailHRS) as RATE
from
select device,time_stamp,
case when usage >0 then 1
else 0 end as ActiveHRS,
'1' as AvailHRS
from
select device,time_stamp,
sum(case
when state = 9 then 0
when state = 0 then 0
else 1 end) as usage
from A
where to_char(time_stamp,'HH24') >= '09'
and to_char(time_stamp,'HH24') <= '19'
and to_char(time_stamp, 'D') in (2,3,4,5,6)
group by device, time_stamp
group by device,time_stamp

Here is the DDL :
desc rumi_all
Name     Null   Type
RUMI_DEVICE      VARCHAR2(20)
STATE         NUMBER(38)
TIME_STAMP      DATE
LOCATION       VARCHAR2(50) Here is some sample data :
RUMI_DEVICE   STATE   TIME_STAMP    LOCATION
10.45.28.86     0     15-JUN-10      WA-102
10.45.28.51     0     15-JUN-10      WA-102
10.45.28.63     0     15-JUN-10      WA-102
10.45.29.47     9     15-JUN-10      WA-120I used the below query to get the util for the hours 9am - 7pm
select rumi_device,time_stamp,
sum(ActiveHRS)/sum(AvailHRS) as RATE
from
select rumi_device,time_stamp,
case when usage >0 then 1
else 0 end as ActiveHRS,
'1' as AvailHRS
from
select rumi_device,time_stamp,
sum(case
when state = 9 then 0
when state = 0 then 0
else 1 end) as usage
from rumi_all
where to_char(time_stamp,'HH24') >= '09'
and to_char(time_stamp,'HH24') <= '19'
and to_char(time_stamp, 'D') in (2,3,4,5,6)
group by rumi_device, time_stamp
group by rumi_device,time_stamp
Acquired Out for the above query :
RUMI_DEVICE      TIME_STAMP     UTIL_RATE
10.45.29.47     15-JUN-10      0.234
10.45.28.63     15-JUN-10             0.123
10.45.29.47     15-JUN-10             0.987
10.45.29.47     16-JUN-10             0.23Desired output :I want 2 extra columns which shows util rate for the above condition i.e 9am - 7pm(core hours) and also opposite to that condition after 7pm - before 9am(say, non core hours)
Desired out put :
RUMI_DEVICE TIME_STAMP Core_Util_Rate   Non_Core_UtilRate

10.45.29.47   16-JUN-10              0.23                  0Hope this helps in answering my question , and also could you please share some document to learn writing nested sql's , i always had tough time in understanding this :-(

Help needed in select query to take date

Hello,
I am using Oracle 11g.
I am using this query
select to_date(to_char(to_date((SOURCE_MONTH||'-'||SOURCE_YEAR),'MM-YYYY'),'Mon-YYYY'),'MON-YYYY') date_
from tab1 a,tab2 b
where b.col2=a.col1;
I have a table with 2 separate varchar columns month and year,
I want to insert the data into another table which has the col type as timestamp.
This query gives me the data as
01-NOV-06 but
i want the data as
01-NOV-2006
What should i do for that?
Thanks

First, get rid of the extra conversions from date to char and back to date:
select to_date((SOURCE_MONTH||'-'||SOURCE_YEAR),'MM-YYYY'),'Mon-YYYY')
from tab1 a,tab2 b
where b.col2=a.col1;Now, your data is safely rendered as a DATE. It knows the full year (i.e.2006). You are just not seeing it formatted the way you like. You could
alter session set nls_date_format = 'mm/dd/yyyy hh24:mi:ss';or give the explicit format you want when you query it (with TO_CHAR).
Please read and understand about DATE datatypes....
http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/sql_elements001.htm#i54330
In particular, search that page for: "DATE Datatype "

Help with a select query

Hi Guys,
For example I have 2 tables:
I wish to list out the owner, table_name, total count of chain row of the table, num rows by joining the below 2 tables.
Can advise how can i do it?
Currently i'm doing it by executing this statement but very slow:
select a.owner_name, a.table_name, count(*), b.num_Rows
from system.chained_rows a, dba_tables b
where a.owner_name=b.owner
and a.table_name=b.table_name
and b.num_Rows>0
group by a.owner_name, a.table_name, b.num_Rows
having count(*)*100/b.num_Rows>10;
TABLE INFORMATION:
1. CHAINED_ROWS (one table name can have multiple chain row id records)
column:
1. owner
2. table_name
3. chain row id
2. DBA_TABLES (one table name only one record)
column:
1. owner
2. table_name
3. num_rows
thanks

Hi,
I think u mis-inteprete my question.
My question is more on how to formulate a sql to get the output i hope so.. and not how to get chain counts.
I wish to list out the owner, table_name, total count of chain row of the table, num rows by joining the below 2 tables.

Help need in selection query

Hi ,
I have a field(test) in ztable(zxxx) whose length is 12 char and while updating it
only 10 digits were updated and there are no zeros in front of the value in order to make it
12 digit.
Now i need this parameter to be included in another program selection screen.
Now i have given it as
parameter : test(12) type n.
it works fine when it has an entry , when it is blank i has to retrieve all records but in this case
i won't because it has a value of 000000000000
noe when i declare like this
paramter : test like zxxx-test.
when my input is 123456, it won't fetch me any value because it has to be 0000123456 because it has been updated like in the table.
There was a purpose in updating this way.
Now my code is like this
parameters : test(10) type n.
select-options :   kostl for zxxx-kostl NO-EXTENSION NO INTERVALS,
      p_uname for zxxx-uname NO-EXTENSION NO INTERVALS.
if test is initial.
select * from zxxx into table itab where kostl in kostl and uname in p_uname.
else.
select * from zxxx into table itab where aufnr = order and
                               kostl in kostl and uname in p_uname.
endif
PLEASE SUGGEST ME IF THERE IS AN ALTERNATE BETTER WAY.
or this is the best way
Thanks

Hi
as per my knowledge what you have done is right.
Thanks
