How to query a row based on its rownum

Dear all,
what is the easiest way to query a row based on its rownum? Suppose I have the following query:
select first_name from employees where rownum<5;
FIRST_NAME
Ellen
Sundar
Mozhe
DavidSo Ellen has rownum 1, Sundar 2 and so on. How can I do it if I just want to query a row where Mozhe is the first_name, which is rownum 3?
Best regards,
Val

You are correct, your way of thinking is wholly innaccurate. Something that can easily be confirmed simply by reading the documentation:

How to suppress a row based on current date - at query level?

In an Bex query report i have suppress rows based on current date.
There is no current date available in query.
there is a date field in the query.
If by chance the date in that field is lesser than current date, I have to suppress that row.
How can this be achieved?

What is the code ofr creating a variable to get values >= to current date?
I have implemented the following code which is not working.
data L_S_range like line of E_T_range[].
CLEAR L_S_RANGE.
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT = 'GE'.
L_S_RANGE-LOW = SY-DATUM.
APPEND L_S_RANGE TO E_T_RANGE[].
Actually i have written in class, which will be inherited in superclass.

How not show duplicate rows based on one field

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0
Hello
I have a query that looks for certain scripts that did not run on a particular day compared to what ran the same day a week ago. We want to include the start_datetime and end_datetime but when I add it to the select statement it brings up all instances of the jobs that run multiple times during the day. Is there a way to exclude the extra rows based on the script_name field?
SELECT instances.script_name,
                         instances.instance_name,
                         REGEXP_REPLACE(master.description,
                                        chr(49814), -- em-dash
                                        '-') description
                                        --instances.start_datetime
                  FROM   xxcar.xxcar_abat_instances Instances,
                         xxcar.xxcar_abatch_master Master
                  WHERE 1 = 1
                  AND    TRUNC(start_datetime) = TRUNC(TO_DATE(:p_StartDate, 'YYYY/MM/DD HH24:MI:SS')) - (:p_NumOfWeeks * 7)
                  AND    Instances.SCRIPT_NAME = Master.SCRIPT_NAME (+)
                  MINUS
                  SELECT script_name,
                         instance_name,
                         NULL
                         --NULL
                  FROM   xxcar.xxcar_abat_instances
                  WHERE 1 = 1
                  AND    TRUNC(start_datetime) = TRUNC(TO_DATE(:p_StartDate, 'YYYY/MM/DD HH24:MI:SS'))

MINUS does a set operation - removing rows from the first set that exactly match the second set.
When you add columns to the first set, you want a more restricted filtering - try a multi-column NOT IN:
To remove multiple runs, group and get min/max
SELECT instances.script_name,
                         instances.instance_name,
                         REGEXP_REPLACE(master.description,
                                        chr(49814), -- em-dash
                                        '-') description,
                         min(instances.start_datetime) start_datetime,
                         min(instances.end_datetime) end_datetime

How to query the rows of a ViewObject programatically?

Hi All,
I'm using View Objects(based on a SQL query) as part of my ADF form. At present my VO contains about 2500 rows. I need to programatically query these 2500 rows of the ViewObject for a particular row.
I'd like to know the best approach to do this.
At present, I am looping around the VO using a for loop, and getting RowAtRange(Index i) and checking each row. I know this is not the best way forward and would like to use any native VO/ADF methods to do this.
I'm not sure if getRowMatch is applicable?
UsingJDev : 11.1.1.4
Thanks

You can use findByKey method, check this

How to retrieving latest row based on a column value

Hi,
Lets consider a scenario. I have a table which has a order number, count column which is our fact, a type column which contains types e.g. (A,B) with A has more priority then B. Now in our graph we are getting all rows i.e. if we have two rows in db for order #1 one for type A and one for type B, then it shows us data from both rows in graph.
But I need only to show one row of type A in this case as A has higher priority than B. The row with type B should not contribute in construction of my graph if type A for same row also exists.
I tried a solution, for which i created a new column at logical level which contain 1 for A and 0 for B. Now i put Max aggregation rule in it to get maximum value which will be row with Type A in our case. But it did not work.
How we will can achieve it in OBIEE?
Thanks.
Aasim Khan.

Hi Steve,
I have a similar requirement... one of the columns in my table is a calculated value based on several xml fields,
<?xdofx:(MATH01+MATH02+MATH03+MATH04+MATH05+AA+AA1)+((FNDCD01+FNDCD02+FNDCD03+FNDCD04+FNDCD05+MCHCD01+MCHCD02) div '8')?>
if the resultant value above is less than 62, i do no want to display this entire row in the output. could you help me wout with this?
thanks

How to send a Row based in a view Object

i has in the app module a method to insert but i want from the baking bean send a Row with the information but not function well
---this is my method in the app module
public boolean CreaCliente1(Row row){
ViewObjectImpl vo =this.getClientesVo();
vo.insertRow(row);
this.getDBTransaction().commit();
return true
in the bean the the method where i asign the data to the object row is
public Row CreaCliente(Row row){
SimuladorAppImpl app = new SimuladorAppImpl();
ViewObjectImpl vo = app.getClientesVo();
Row row = vo.createRow();
row.setAttribute("IdCliente",0);
row.setAttribute("NuDocumento",this.getNumeroDocumento());

then i invok the method with the command button but apers a error
how is the best way to do this
thansk
Edited by: JuanAndresDeveloper on 10-feb-2009 8:05

You can't just simply create a new application module like that:
SimuladorAppImpl app = new SimuladorAppImpl();This will not work!
An other thing to mention is that you don't push Row objects from the view controller to the server side (this breaks the MVC paradigm).
If you have to create a new row, you can create a method in your application module and call this method either with a number of attributes or a POJO object holding the values.
Remember too that your new row normally have a primary key attribute which you have to fill with a distinct value for each row.
To get the application module from within a backing bean you can look at ADFUtils.getApplicationModuleForDataControl("YourAppModuleDataControl");Search the FOD application for the ADFUtils class or this forum.

How to exclude entire row based on single column

Hello there,
I'm trying to hide an entire row if column does not equal 'E' and can't seem to get it to work. Here is code i am using inside the group:
<?for-each:current-group()?>
<?if@row:recordType != 'E'?><?end if?>
<?end for-each:current-group?>
What am i missing? Also note that the column i am trying to filter on is in the xml but not being displayed in the report.

How to look for bundle based on its content (actions)?

Hello,
I want to have a list of all bundles that use a specific system variable, for exemple ${NSSREPO}.
It is possible to make an SQL query to do it or do you know a way to get such list?
I do not want to export all bundles on XML files and then look for the string.
Thanks in advance.

Query - restricting rows based on specific combinations of columns

I have two columns in two different tables T1 and T2 like below
T1.Column1 T2.Column2
1 a
2 b
3 c
4 d
5 e
I need all the combinations of values in the columns, which I can choose like
select T1.Column1, T2.Column2 from T1, T2 ------ (Without specifying any join ie. cartesian product)
But, in those, combinations, I need to restrict the following combinations, from not being selected - (1,b), (1,c),(3,b), in the same sql, or using a subquery. I am not able to achieve this after several attempts. Can any one help?

Just pad it and check
SQL> select no,name from a,b where to_char(no)||name not in ('1b','1c','3b')
2 /
        NO N
         1 a
         1 d
         1 e
         2 a
         2 b
         2 c
         2 d
         2 e
         3 a

How can i update rows in a table based on a match from a select query

Hello
How can i update rows in a table based on a match from a select query fron two other tables with a update using sqlplus ?
Thanks Glenn
table1
attribute1 varchar2 (10)
attribute2 varchar2 (10)
processed varchar2 (10)
table2
attribute1 varchar2 (10)
table3
attribute2 varchar2 (10)
An example:
set table1.processed = "Y"
where (table1.attribute1 = table2.attribute1)
and (table1.attribute2 = table3.attribute2)

Hi,

Hi, Frank
taking nulls into account, what if some attributes are null ;) then the query should look like
NOT TESTED !
update table1 t1
set processed = 'Y'
where exists(select null
from table2
where lnnvl(attribute1 != t1.attribute1)
and exists(select null
from table3
where lnnvl(attribute2 != t1.attribute2)
and processed != 'Y'Regards
EtbinYes, you could do that. OP specifically requested something else:
wgdoig wrote:
set table1.processed = "Y"
where (table1.attribute1 = table2.attribute1)
and (table1.attribute2 = table3.attribute2)This WHERE clause won't be TRUE if any of the 4 attribute columns are NULL. It's debatable about what should be done when those columns are NULL.
But there is no argument about what needs to be done when processed is NULL.
OP didn't specifically say that the UPDATEshould or shouldn't be done on rows where processed was already 'Y'. You (quite rightly) introduced a condition that would prevent redo from being generated and triggers from firing unnecessarily; I'm just saying that we have to be careful that the same condition doesn't keep the row from being UPDATEd when it is necessary.

Mudassar

Hi Mudassar,
The issue is caused by the order in which the parameters appear in the report data tab can be difference between our report execution and it failing. In other words, “Parameter2” is execution before parameter “A” due to this issue. We can adjust the parameter’s
order to solve the issue.
If “Parameter2” is parameter “A”, we cannot use that expression. Because fields cannot be used in report parameter expression, if we want to display the first value returned from a query as default value, we have to fill the “Specify values” text box with
the specific value in Default Values dialog box.

Jigar

Hi,
Follow the below steps . Definately your issue will bve resolved.
Let us suppose you are printing following fields
PH &v_text&
PH &v_text1&
PH &v_text2&
you will get the output as you expected.
and if you have any conditions for these fileds
/: if v_text is not initial.
PH &v_text&
/: endif
PH &v_text1&
PH &v_text2&
if you have data in each field then you will get output as expected .
But when v_text is initial.
the data will be moved up wnhich is happening in your case.
so what you need to do is?
/: if v_text is not initial.
PH &v_text&
/: else
PH (Here you need to mention empty line with same paragraph format
/: endif.
PH &v_text1&
PH &v_text2&

How to create an LOV based on a dynamic query

Hi,
Can someone tell me how to query a dynamic query for LOV. On my base page I have a dropdown-box (that will show the table names for searching) and is dynamically populated based on users access e.g. if user A logs in he may see 5 values (these values are basically table names) in a drop down if user B logs in he may see 10 values. I also have two input fields one field a user can enter value and the other field is read only and a torch icon for LOV so the user can search and select values that are populated in the input fields on the base page.
How can I have my LOV that takes in a value selected in the dropdown and anyvalue entered in one of the input fields and search in the table selected in the dropdown box.
Basically my LOV should do a search on the table and some search value passed when clicking on the torch icon. So a user can select any table-name in the drop down and my LOV should do a search only on the selected table. Once on the LOV Popup want to have a search field there but it only searched on the table selected in the dropdown on the based page. And the selected value on the LOV Popup page gets populated in fields on the base page.
Any help is appreciated.
Thanks
