Sub query with conditions

Hi,
Is it possible to run a sub query with conditions? I keep receiving an error 'Registration Data' -2006.
For example, here is a simplified query which gives the error...
SELECT T1.CardCode FROM
SELECT T0.CardCode FROM OCRD T0 WHERE T0.CardCode = '[%0]'
) T1
FOR BROWSE
Thanks for any help,
Robin

SBO SQL-parser sometimes kidding. My solution is to use temptables/views/storedprocedures.
It's faster then "unbugging" parser <b>:)</b>
in your case that can be like the following:
SELECT T0.CardCode INTO #temp FROM OCRD T0 WHERE T0.CardCode = N'[%0]'
SELECT qq.CardCode FROM #temp qq FOR BROWSE
BTW: registration data error is usially says us about %-argument reason

Sub query with order by

Hi ,
I have created a sub query with order by on a column.( i have cutomized the IKM control append to put order by).I can see the order by condition.If i use this subquery(yellow interface) in main query(is also yellow interface) i can't see the order by condition

Hi,
Add a new KM step with the SQL you want to use for the sub query and select the +"Use Current Command for Derived-Table sub-select statement"+ checkbox. This new step can be the last one of your IKM.
Basically, you can copy the select statement of the "Insert new rows" step.

Please suggest a select query / sub query with out using any subprograms or

source table: Three columns ORIGIN, DESTINATION,MILES
Origin      Destination Miles
Sydney      Melbourne      1000
Perth      Adelaide      3000
Canberra      Melbounre      700
Melbourne      Sydney           1000
Brisbane      Sydney           1000
Perth      Darwin           4000
Sydney      Brisbane      1000
out put :Three columns ORIGIN, DESTINATION,MILES
Duplicate routes are to be ignored so the output is
Origin      Destination      Miles
Sydney      Melbourne      1000
Perth      Adelaide      3000
Canberra      Melbounre      700
Brisbane      Sydney           1000
Perth      Darwin           4000
Please suggest a select query / sub query with out using any subprograms or functions/pkgs to get the out put table.

Here's one way, without any functions:
SELECT     a.*
FROM           source_table a
LEFT OUTER JOIN      source_table b ON   a.origin          = b.destination
                                      AND a.destination      = b.origin
                      AND a.miles          = b.miles
WHERE   b.origin > a.origin    -- Not b.origin > b.origin
OR     b.origin IS NULL
;If you'd care to post CREATE TABLE and INSERT statements for your sample data, then I could test this.

Sql query with conditions and calculations???

Hi,
how I can build a query with conditions and calculations?
E.g. I've got this table
Start          | End     |     Working Place     |     Mandatory
01-JAN-13 | 11-JAN-13 |     Office           |          1
14-JAN-13 | 25-JAN-13 |     Home Office      |     0
04-MRZ-13| 15-MRZ-13 |     Office           |          0
11-FEB-13 | 22-FEB-13 |     Office           |          1
Now if column working place=Office and column mandatory=0
the new column "price" has to calculate: (End-Start)* $25.00
and if working place=Office and column mandatory=1
the "price" column has to calculate: (End-Start)* $20.60
else $0.00
I tried it with the case statement but I didn't know how
to calculate my values and display it to the virtual column "price".
Something like
case
when Working_Place = 'Office' and Mandatory=1
     then ...
else '0.00'
end as PRICE
Or is it not possible?
Edited by: DB2000 on 12.03.2013 05:09

Use CASE:
select start_dt,
        end_dt,
        working_place,
        mandatory,
        case
          when working_place = 'Office' and mandatory = 0 then (end_dt - start_dt) * 25
          when working_place = 'Office' and mandatory = 1 then (end_dt - start_dt) * 20.60
          else 0
        end price
from tbl
START_DT END_DT    WORKING_PLA MANDATORY      PRICE
01-JAN-13 11-JAN-13 Office               1        206
14-JAN-13 25-JAN-13 Home Office          0          0
04-MAR-13 15-MAR-13 Office               0        275
11-FEB-13 22-FEB-13 Office               1      226.6

Performance of APD with source as 'Query with conditions'

Hi,
I have a question regarding the performance of an APD query with conditions when it is run in the background.
I have an infocube with 80 million records.I have a query to find Top 15 (Condition In query) Customers per territory.
With the help of an APD Query (Source) i wanted to populate the details (customer category , etc) of the Top 15 Customers into a DSO (Target)
Right now it takes 6 minutes to run the query in web.
I wanted to know how feasible it is to use an APD (run in backgrnd) to dump the results of the BEx query (which has conditions Top 15) into DSO.
Also , what other options do i have ?
Appreciate your answers.
Regards

Thomas thanks for the response. I have checked the file on the app server and found that the lines with more than 512 characters are being truncated after 512 characters. Basis team is not aware of any such limits on the app server. I am sure few on the forum would have extracted data to a file on the application server using APD. Please note that the file extraction to the client workstation is working as expected (posts lines more than 512 characters).

Missing Result Rows on Query with Conditions

I have a query that has a condition to show only items over $2500.00. We have a result row that shows for plant when the condtions is not on but once the condition is set that result row goes away. Does anyone know how to get a result row to show up on reports with conditions? Thank you.
Caroline

Hi Caroline,
In BI 7.0, you goto do this in Query Designer.
Select any of your characteristic in the designer and choose Display Properties to always display result.
Then run the query.

SQL Report query with condition (multiple parameters) in apex item?

Hello all,
I have a little problem and can't find a solution.
I need to create reports based on a SQL query or I.R. Nothing hard there.
Then I need to add the WHERE clause dynamically with javascript from an Apex item.
Again not very hard. I defined an Apex item, set my query like this "SELECT * FROM MYTAB WHERE COL1 = :P1_SEARCH" and then I call the page setting the P1_SEARCH value. For instance COL1 is rowid. It works fine.
But here is my problem. Let's consider that P1_SEARCH will contain several rowids and that I don't know the number of those values,
(no I won't create a lot of items and build a query with so many OR!), I would like sotheming like "SELECT * FROM MYTAB WHERE ROWID IN (:P1_SEARCH) with something like : ROWID1,ROWID2 in P1_SEARCH.
I also tried : 'ROWID1,ROWID2' and 'ROWID1','ROWID2'
but I can't get anything else than filter error. It works with IN with one value but as soon as there are two values or more, it seems than Apex can't read the string.
How could I do that, please?
Thanks for your help.

For an IR—and improved security avoiding the risk of SQL Injection—use a <a href="http://download.oracle.com/docs/cd/E17556_01/doc/apirefs.40/e15519/apex_collection.htm#CACFAICJ">collection</a> containing the values in a column instead of a CSV list:
{code}
SELECT * FROM MYTAB WHERE ROWID IN (SELECT c001 FROM apex_collections WHERE collection_name = 'P1_SEARCH')
{code}

How to write multi row sub query with the row containing range of values?

Hi all,
I have to include a column which contains weight ranges and it should come fom table called "report_range_parameters"
The following query will reutrn those weight ranges.
select report_parameter_min_value || ' -> ' || report_parameter_max_value
          from report_range_parameters
         WHERE report_range_parameters.report_parameter_id = 2359
           and report_range_parameters.report_parameter_group = 'GVW_GROUP'
           and report_range_parameters.report_parameter_name = 'GVW_NAME'
                    The below query should return the values group by those weight ranges.
How could I write that sub query?
select   SUM(NVL("Class 0", 0)) "Class 0" ,
            SUM(NVL("Class 1", 0)) "Class 1" ,
            SUM(NVL("Class 2", 0)) "Class 2" ,
            SUM(NVL(" ", 0)) "Total"
     FROM (
             SELECT report_data.bin_start_date_time start_date_time,
                    SUM(DECODE(report_data.gvw, 0, report_data.gvw_count, 0)) "Class 0" ,
                    SUM(DECODE(report_data.gvw, 1, report_data.gvw_count, 0)) "Class 1" ,
                    SUM(DECODE(report_data.gvw, 2, report_data.gvw_count, 0)) "Class 2" ,

             GROUP BY report_data.bin_start_date_time
          ) results
   RIGHT OUTER JOIN tmp_bin_periods
                 ON results.start_date_time >= tmp_bin_periods.bin_start_date_time
                AND results.start_date_time < tmp_bin_periods.bin_end_date_time
           GROUP BY tmp_bin_periods.bin_start_date_time,

Hi,
Assuming the following 4 things:
(1) report_range_parameters contains data like this, from your [previous thread|http://forums.oracle.com/forums/message.jspa?messageID=3541079#3541079]
id group      name         min_value      max_value
1   gvw_group gvw_name      0              5
2   gvw_group gvw_name      5              10
3   gvw_group gvw_name     10              15(2) max_value is actually outside the range (that is, a value of exactly 5.000 is counted in the '5->10' range, not the '0->5' range)
(3) the range has to match some column x that is in one of the tables in your main query
(4) You want to add that column x to the GROUP BY clause
then you shopuld do somehting like this:
select   SUM(NVL("Class 0", 0)) "Class 0" ,
            SUM(NVL("Class 1", 0)) "Class 1" ,

            SUM(NVL(" ", 0)) "Total"

                    SUM(DECODE(report_data.gvw, 2, report_data.gvw_count, 0)) "Class 2" ,
                    SUM(NVL(report_data.gvw_count, 0)) " "
              FROM report_data

Query with condities

Hi
Iu2019ll try to make a query to get a material number with the price (condition). I use the tables KONP and A304, but I get no results.
In table KONP Iu2019ve the condition record number and the amount; in table A304 Iu2019ve the condition record number and the material number. So I use as selection the material number in the table A304 to get the amount from KONP. But the query said no results.
When i use trx SE16 for both tables i'll will get the results that i want.
Can anyone tell me what Iu2019m doing wrong or better can give me the solution?
Thanks,
Peter

Hi Peter,
Go to Transaction SQVI and select the table join while creating the query and by default the tables are getting getting connected with many fields... remove all by right click on relation and join both the table with one field only i.e. "KNUMH" (condition record number)
please try it and confirm.
It is working fine.
Thanks & Regards,

Using a query with condition as a source to fill an ODS

Hi all,
i need your help guys, i got the task to take the data from a BI Query and fill and ODS monthly, it means, i need taking like a picture of the data of the report at the end of each month, in this way i bring the data and fill a ods or cube monthly.
I tried to do it with APD and doesnt work because this query has many conditions, now i tried with the RSCRM_BAPI and this when execute last too much, this execution has 2 days and doesnt finish yet, i can think this is not a factible way either, what else can i do? help

hi,
You need to write a code to get the key figure and characterstics value.
First step is to defined the structure of all the field that you want to read.
This table I_AXIS_DATA will contain the characterstics.
This table I_CELL_DATA will contain the keyfigure.
Please find the code.
            READ TABLE I_AXIS_DATA INTO WA_AXIS_DATA WITH KEY AXIS = '001' .
            IF SY-SUBRC = 0.
              LOOP AT WA_AXIS_DATA-SET INTO WA_SET.
                    INDEX = INDEX + 1.
                    IF WA_SET-CHANM = 'infoobject name'.
                      WA_ROW_COL-fields = WA_SET-CHAVL_EXT .
                    ENDIF.
                    IF WA_SET-CHANM = 'infoobject name'.
                      WA_ROW_COL-field2 = WA_SET-CHAVL_EXT.
                    ENDIF.
              ENDLOOP.
            ENDIF.
******* POPULATE COLUMNS AGAINST ROWS
            CLEAR WA_ROW_COL.
            V_COUNT = 1.
            INDEX = 1.
            LOOP AT IT_ROW_COL INTO WA_ROW_COL.
              WHILE ( V_COUNT <= V_NUMOFKEYF ).
                    READ TABLE I_CELL_DATA INTO WA_CELL_DATA INDEX INDEX.
                    IF V_COUNT = 1.
                      WA_ROW_COL-keyfigure = WA_CELL_DATA-FORMATTED_VALUE.

Universe on Bex Query with Condition

Hi,
I'm working on creating a WebI version of a Bex Report. I've created a universe on top of the Bex Query and then a WebI report based on the Universe. The Bex Query contains 4 conditions. They allow optional filtering of two measures, Less Then or Equal and Greater Then or Equal. The conditions are applied at the employee level of the results set, so for example, if an employee's total sales is greater than 50 and the user enters 50 for the condition then none of that employee's rows of data will appear.
A single filter was created in teh Universe containing all four conditions. I had to update the syntax as they were all brought in using Equals instead of the GreaterorEqual and LessOrEqual. I also updated the filter key to use the @Select and the correct dimension.
In the WebI report, only the two using LessOrEqual are functional. The two conditions that utilize GreaterOrEqual will only remove individual rows, not the enter set of rows for that employee. I've set the aggregation to sum instead of Database Delegated for the two affected measures.
If anyone has any input on how to get the GreaterOrEqual conditions functioning properly, or a workaround that will remove all rows for an employee when their sales are not above a cert number, it would be greatly appreciated.
Thanks,
Jeff

Also here is the syntax for one of the filters that is not functioning properly.
<OPTIONAL><FILTER KEY="@Select(Total Quantity of Adjustments\Total Quantity of Adjustments)"><CONDITION OPERATORCONDITION="GreaterOrEqual"><CONSTANT CAPTION="@Prompt('Minimum Quantity of Adjustments','N',,mono,free)"/></CONDITION></FILTER></OPTIONAL>

A3 - 2

Hi,
If you want to get 0 counts for names that don't have any low ids, then use a CASE expression instead of a WHERE clause.
You didn't post CREATE TABLE and INSERT statements for your sample data, so I'll use scott.emp to illustrate.
Say you want to see how many sals in each job are under 3000, like this:
JOB       UNDER_3_CNT
CLERK               4
SALESMAN            4
PRESIDENT           0
MANAGER             3
ANALYST             0
Here's one way to do that:
SELECT    job
,         COUNT (CASE WHEN sal < 3000 THEN 1 END) AS under_3_cnt
FROM      scott.emp
GROUP BY job
This shows that there are ANALYSTs and PRESIDENTs in the scott.emp table; there just don't happen to be any with sals under 3000.

Hi,
the problem is the big for all entries table.
Your 20.000 records FAE will be split into SEVERAL sql statements depending on the size of the table.
Where do you get the it_auftrn from?
If it's another transparent table try to JOIN this table to your big table.
SELECT rsnum
            rspos
            matnr
            werks
        lgort
            shkzg
            aufnr
            bdmng
            enmng
            FROM resb JOIN tab_auftrn on resbrsnum = tab_auftrnauftrn
            AND   xloek NE 'X'
            AND   postp NE 'X'
            AND   resbbdmng GE resbenmng.
Make sure that your WHERE filter and the JOIN keys on both tables are supported by indexes.
150.000 records about of 40 Mio. can definitly be serviced by an appropriate index:
i.e. Index fields (check your PK or secondary indexes):
rsnum
enmng
aufnr

Filter query with sub query using Dropdown box

Dear Community,
I have 2 queries
1. Main Query with 2 fields: Project | Project value
2. Sub Query with 2 fields: Project group | Project
Project group can be belonging to number of projects and project can be belong to number of project group (Many to Many).
My customer wants the main query will open without any filtering.
When I choose project group from WAD dropdown box, the main query will filtering all the projects that belong to the project group.
I create WAD; define dropdown box as sub query, and Analysis as main query.
In the dropdown box I choose "data binding" char and create command "set selection state by binding" (project to project) but it doesnu2019t work.
I also try to do this by Replacement Path in the main query, but the variable requires the attribute will be ready for input.
Thanks a lot
Yaniv

I am not sure about your comments on replacement path variable. Without having tried it, here is what I would have attempted:
The main query needs to use a replacement path variable for Project that is replaced by the results of the sub-query. Sub-query would have a regular input variable for project group. (as a quick test, if you had one analysis item for main query with variable input enabled, it should prompt you to enter Project group).
Now the drop-down needs to be associated with a javascript function. The javascript function needs to implement command "Set variable state" for the main query data provider to selected value of the drop-down.
The drop-down should be associated with the sub-query data provider, just used to populate the list of values in drop-down.
