Dyanmic SELECT clause

Hi,
I need to have a dynamic selsction of fields in a select query.
I am using the same trick used in the where clause for te SELECT clause as follows:
concatenate 'RBUKRS' 'RACCT' 'RZZRCNTR' v_field
           into v_sel separated by space
.   select (v_sel)
      from zgroupt
      into table i_zgroupt
    where racct eq s_hkont..
But this doesnt work.
I have a requirement to fetch certain fields based on some conditions. How do i achieve it ?
Regards,
Stock

Hi,
Here is the dynamic where clause example code
PARAMETERS: carr_id TYPE spfli-carrid,
            conn_id TYPE spfli-connid.
DATA:       where_clause TYPE STRING,
            and(4),
            wa_spfli TYPE spfli.
IF carr_id IS NOT INITIAL.
CONCATENATE 'CARRID = ''' carr_id '''' INTO where_clause.
and = ' AND'.
ENDIF.
IF conn_id IS NOT INITIAL.
CONCATENATE where_clause and ' CONNID = ''' conn_id ''''
    INTO where_clause.
ENDIF.
SELECT * FROM spfli INTO wa_spfli WHERE (where_clause).
WRITE: / wa_spfli-carrid, wa_spfli-connid, wa_spfli-cityfrom,
           wa_spfli-cityto, wa_spfli-deptime.
ENDSELECT.

Decimal Separator in SELECT Clause

Hi
I have the following decimal format parameters:
SQL> select value
2 from v$nls_parameters
3 where parameter = 'NLS_NUMERIC_CHARACTERS';
VALUE
If I show a number with decimal I get a comma as the decimal separator
SQL> select 10/100 from dual;
10/100
,1
But if I use a decimal separator in the SELECT clause I get:
SQL> select 100 * 1,1 from dual;
100*1 1
100 1
It doesn't work. But using a period as the decimal separator works:
SQL> select 1.1 * 100 from dual;
1.1*100
110
Maybe this is something I've never had to deal with before but I thought that the numeric format applied to the sql results and also the numbers that you used in the sql clauses.

Hi,Néstor,
user594312 wrote:
... I thought that the numeric format applied to the sql results and also the numbers that you used in the sql clauses.No; it applies to results, and it can affect implicit conversions, but it doesn't apply to SQL code.
The period (or dot, '.') is always the decimal separator in numeric literals. There is no way to change that.
Think how confusing it would be if it did apply to SQL code! For example:
WHERE   num_col IN (1,2)Are we comparing num_col to 1 value or 2 values? Whichever it is, what if we wanted to do the opposite?
If you really wanted to use comma as the decimal separator, you could have to use strings, not numbers, and that could be a lot less efficient.
For example:
SELECT 100 * TO_NUMBER ('1,1')    -- This assumes your NLS settings are correct
FROM    dual;Of course, efficiency won't be an issue when you're selecting 1 row from dual.

&param lexical variable in SELECT clause

Is there a way to get Oracle*Reports to accept a lexical variable in the SELECT clause? The example is:
SELECT
table.column1,
table.column2,
&PARAM as column3
FROM
table
I am already using lexical variables in the WHERE clause, but getting one to work in the SELECT clause has thus far failed.
The SQL is accepted if :PARAM is used in place of &PARAM, but I am unable to actually vary the selected column this way.
The bind variable PARAM has the following code behind it in a BeforeReport trigger:
IF :ANOTHER_PARAM := 'ALL' THEN
:PARAM = 'ALL'
ELSE
:PARAM = 'table.column3'
When using :PARAM in the SELECT clause, the literals 'table.column3' are returned, not the contents of table.column3.

Sorry for the wasted bandwidth. I found a solution. Here it is:
SELECT
table.column1,
table.column2,
CASE :P_USER
WHEN 'ALL' THEN 'ALL'
ELSE table.column3
END as column3

Merge can't accept a variable in the select clause?

oracle 10.2
I have a stored procedure.
I have a variable, vseq, which I set a sequence variable. With all other sql statements I can do
insert into table a
select vseq
from dual;
Apparently a merge can't handle variables in the select clause. I get an error. I can get it to work when I hard code a value.
this is ridiculous...

Using @Prompt in the SELECT clause (?)

Error Messages: "Parse failed: Exception: DBD, ORA-00903 invalid table name State N/A"
Hi! I'm bewildered -- we have an object that parses but when I try to reproduce this object, it does not.
We have a universe that's been in production for several years using an object developed by another designer who's no longer with the company. This object is a dimension, datatype is character, and there's no LOV associated. The SELECT statement in this object is
decode(@Prompt('Select Snapshot Month','A','Object Definitions\CY Month Snapshot',MONO,CONSTRAINED),'00-Previous Month',to_number(to_char(add_months(sysdate,-1),'MM')),'01-Current Month',to_number(to_char(add_months(sysdate,0),'MM')),'01-January','1','02-February','2','03-March','3','04-April','4','05-May','5','06-June','6','07-July','7','08-August','8','09-September','9','10-October','10','11-November','11','12-December','12')
This object parses. The client uses the object in the select clause to capture the "month of interest" for the report. So the report may be for the entire year's data which is graphed to show trends, but there's a table below the graph which is filtered to show just the month of interest. Typically they use the value "00-Previous Month" so they can schedule the report and it will always show the last month's data.
Problem
The original object parses.
If I copy the object within the same universe, it parses.
If I copy the code into a new object in the same universe, it doesn't parse
If I copy the code into a new object in a different universe, it doesn't parse
If I copy the object to a different universe, then edit the LOV reference, it doesn't parse
If I create any new object having @Prompt in the SELECT statement, it doesn't parse.
If another designer tries - they get the same thing.
What am I missing? Obviously someone was able to create this successfully.
On the brighter side
The object I created in a new universe (which doesn't parse in the universe) seems to work fine in the report.

Seems that, the prompt syntax is correct.
But the condition is not correct.
You are taking the prompt value and not doing anything. That could be one issue for this error.
I believe that, you just want to capture the prompt value use it in report level and do not want to apply as a filter.
So, use the condition as follows.
@Prompt('Select Grouping','A',{'A','B','C'},mono,constrained) = @Prompt('Select Grouping','A',{'A','B','C'},mono,constrained)
Hope this helps!

How to append new field in select clause of dynamic VO through CO

Hi
My VO is VO Extension below. In the seeded VO (oracle.apps.per.selfservice.objectives.server.PerObjPerfRatingsVO) doesn't include 2 fields that I want to add in VO.
oav = (OAViewObject)oam.createViewObject("FaoWorkPerObjPerfRatingsVO", "oracle.apps.per.selfservice.objectives.server.PerObjPerfRatingsVO");
Could you please provide me the coding to append 2 new fields in VO Extension approach. I would like to append them in select clause.
Thank you.

Using a select clause in the column formula in an Analysis

Hi all,
Is there a function or syntax that I can use to simulate a "SELECT" clause in the column formula of an Analysis? What I am trying to achieve is displaying a measure from a specific fact record into the current record. For example, if the current record displays "Region","position", and "salary", I would like to add an additional column called "compared to" in which I can display the "salary" measure from another specific fact record whose attributes I know.
Is there a function/statement that I can use to achieve this?
Thanks

Hi,
U can't do it in Edit formula column..it's possible below one
Add SQL filter in that column then follow blow steps
Convert this filter to SQL
i.e : add more option to sql here u can write SQL query in that column
Thanks

You can check this and change your code by taking this as an example. I just noted down with simple one input and return as collection type

How to remove column name in select clause

Hello Guys,
I just want to remove a column name in select clause. Because, I don't want to write all column names. I hope I express myself.
In other words, I want the following.
Select   * - unwanted_column from table;
instead of this
Select col1, col2, col3, col4, ........ col 10000 from table;

Hi,
Sorry, there's nothing in SQL that means "all columns *except* ...". As the others have said, the only way to get those results in SQL is to list all the columns you do want.
Your front end may have some feature that allows you to hide a specific column. For example, in SQL*Plus, you can use <tt> COLUMN ... NOPRINT </tt> , like this:
COLUMN      dname     NOPRINT
SELECT       *
FROM       scott.dept
ORDER BY dname
;Output:
`   DEPTNO LOC
        10 NEW YORK
        40 BOSTON
        20 DALLAS
        30 CHICAGOThere is a column called dname in the scott.dept table; the query above actually uses it. But, because of the COLUMN command, SQL*Plus won't display that column.

Maximum no. of columns allowed in SELECT clause - Urgent please

Hi,
I am constructing SQL query dynamically in a stored proc. based on user inputs. I am getting following error when I have around 400 columns in my SELECT clause. FROM, WHERE, GROUP BY clauses are same eventhough I have 30 columns and I don't have any problems here. Can anyone please let me know what is maximum no. of columns allowed in a query. I am working on Oracle 9i Release2.
Thanks in advance.

ORA-01467 sort key too longIt's not the SELECT clause that causes this, it's most likely the GROUP BY clause. Basically, the columns in the GROUP BY clause have to fit comfortably within a single database block. Does that sound like it might be a problem with your query?

CQL SELECT clause syntax

Hi all
I have a small question regarding the SELECT clause syntax.
In my CEP application I'm processing events which hold several properties, mostly primitives, but a few of type java.awt.Point.
I can select the Point object itself in the SELECT clause, but I don't know how to reference the x / y properties of the Point object.
e.g -
SELECT int1, int2, string1, string2, point1 - works fine.
SELECT int1, int2, string1, string2, point1.x - query won't get parsed.
I did manage to access the x / y properties using a custom java method that gets the Point object and returns the x / y properties.
Can I reference the x / y properties directly in the CQL query?
Thanks,
Roy
Edited by: user8868221 on Feb 17, 2010 10:59 AM

Hi,
What you are doing is correct. CQL currently only supports a small set of built-in types, so if your event contains a property of a type like Point, then you need to use a user-defined function to access and manipulate that property. This is discussed in the CQL documentation:
2.2.2 Handling Other Datatypes Using a User-Defined Function
Support for Java types and custom user-defined classes is coming in a future release.
Hope that helps.

Problems with query with more than 20 values in the select clause

I have a region based on a function returning a SQL query. It needs to have more than 20 values in the select clause. When I run the page I get a no data found error in the region. I managed to reproduce this behavior with just the following as the select returned by the function:
select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21

I am running the 1.3.9.00.15 release of Marvel on 9.2.0.2 of the db on Solaris.

Hello Raju,
I will email you the connection settings when I return to the office.
One thing I should have mentioned: The sql string is returned from a package in the db, so the query region text I originally posted isn't quite correct.
it is something like:
declare
begin
return my_pkg.my_fnc;
end;
the stored package is nothing more than:
package my_pks is
funtion my_fnc(i_test_param in varchar2) is
begin
return 'select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20, 21 from dual';
end;
end;
Sorry for the inaccurate info in the first post, but I am away from the server in question right now.
