Function NVL in query

I have employees table and query like this:
comp_id, emp_id, region_id
a------------1----------reg1
a------------2
a------------3----------reg1
select emp_id from employees
where comp_id = :compId
and region_id = NVL(:regId, region_id)
if I fill parameter :compId = a and :regId=null, the result of query is 1 and 3,
whereas I want the result is show all the employee (1, 2, 3).
Could you help me how to make query, if I fill parameter :compId = a and :regId = null, the result of query is show the all of employee.
Thanks

This is one way of doing it.
select emp_id from employees
where comp_id = :compId
and NVL(region_id, '-1') = NVL(:regId, -1)I must admit that the requirements are not clear at all. Since, you have read the Link provided by sb92075, why not post some table structures, insert scripts (Sample) and the desired data from the Sample data. It clarifies a lot. You will have to use less words, and less the confusion for readers. Isn't it?

Column order in SQL Query (PL/SQL function returning a query)

Hi,
when I define a PL/SQL function returning a query inside a region, I often find that the column order is arbitrarily changed.
How do I enforce the column order ?
Bye,
Flavio

I removed the 11th column called service_name from this dynamic query: and now the report says: report error:
ORA-01403: no data found. I messed around with the Headiuns Type. It was set to Custom. I changed it to Column Names. There is no difference.
I am not sure how to fix?

Function in a query causing a problem ................

Hello Gurus
I have a problem with my select statement which contains 2 function in it. These functions cause the query to run slow. I have cross checked with all the indexes, statistics and index used within the function they are all correct.
Please some one tell me why is this happening. There was a database crash since then this has started to happen. I have revalidated the fucntions and indexes, still it does not help any.
A questions comes to my mind will it be solved by pinning these functions in memory? and how that could be done.
Please help me at the earliest.

Basic functions (high) in query formula for highest # of days past due

Hi All,
I hope you can help. I am trying to create a formula in a query for FIAR Line Item Cube (0fiar_c03). I would like to calculate the hightest number of days past due for open line items. There is an operator 'high' in basic functions within the query formula. Is it possible to use this?
Regards,
Cheryl Adamonis

There is a workaround usind conditions.That is you can try to filter the top 10 % or top 10 after calculating the no of days past.However this way you will not be displaying complete dataset

Report- Pl/sql function returning sql query parsing page items as text?

Hi Team,
I am facing a strange issue .
I have four page items namely
1)JOB_CODE
2)MIN_EXP
3) MAX_EXP
4) SOURCES1
I have a report of the type "Pl/sql function returning sql query"
declare
v_sql varchar2(4000);
begin
if (:JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql:= 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:JOB_CODE IS NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MIN_EXP IS NULL and :JOB_CODE IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years <= :MAX_EXP and V_REQUIREMENT = :JOB_CODE and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MAX_EXP is null and :JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then

end if;
insert into query_list values (v_sql);
insert into debug values (:JOB_CODE , :MIN_EXP , :MAX_EXP , :SOURCES1);
return v_sql;
end;
Please not that I am insertin the query into a table called Query_list and the page item values into the table called Debug thru the pl/sql function which returns teh query.
Now I select the data from the debug tables.
select unique(query) from query_list;
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like '%:SOURCES1%'
select * from debug;
JOBCODE     MINEX     MAXEX     SOURCE
21     1     10     donkeyHire
And if I run the query in sql I get some records returned
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = 21 and v_experience_years >= 1 and v_experience_years <= and source like 'donkeyHire'
V_CANDIDATE_ID     V_FNAME     V_CURRENT_EMPLOYER     V_EXPERIENCE_YEARS
2     Vengu     Andale Tech     4
But the record does not show up in the report!
does this type of report parse page items as text?
Why is it so?
Waiting for an early reply.
Thanks,
venkat

Venkat - You don't want to put ':SOURCES1' in quotes like that.

Issue with running PL/SQL function returning Sql query

hi, I am trying to create a report region by using the option of PL/SQL function returning sql query.
I notice that it's very slow for the report region page to show up. In my PL/SQL function body, there are only 3 steps, first update all the 10 rows of varchar2 fields to null,then insert values to those fields, then select all from the table to show report results. It takes more than 5 minitues for the page to load up, how ever, if i run those steps in SQL*Plus, it only takes a couple of seconds to finish. Any suggestions?
Thanks,

Sergio, the codes are as followed,
Declare

update info_table
set "TOTAL" = '',
"#CM" = '',
"%CM" = '',
"#CA" ='',
"%CA"=''
where "ID"<=10;
// set all data in column Total to null,there is only 10 rows in the table
update info_Table set Total = vTotal,
"#CM" = vCM
(those variables hold user key-in Text filed value)
where ID = 1;
return q;

Should your query be a valid SQL query?
I can't think that the query you have would be valid in a SQL plus window.

On Submit process not firing -report (PL/SQL function returning SQL query)

Can anyone suggest possible causes / solutions for the following problem?
I have a report region that uses a PL/SQL function returning SQL query. The report allows the user to update multiple fields / rows and then click a button to submit the page which should run the On-Submit process to update the database. However the process does not run and I get a 'HTTP404 page cannot be found' error; and when I navigate back using the Back button I cannot then navigate to any other page in my application without getting the same error. The button was created by a wizard selecting the options to submit the page and redirect to a (same) page. The button does not actually have a redirect in its definition but the wizard created a branch to the same page which should work and the button has the text 'submit as SUBMIT' next to it so it appears to be set up correctly.
I have recreated this page several times in my application and I cannot get the On-Submit process to run. However I have created a cut down version of the same page in the sample application on apex.oracle.com at http://apex.oracle.com/pls/otn/f?p=4550:1:179951678764332 and this works perfectly so I am at a loss to understand why it does not work in my application. I cannot post any part of the application itself but if anybody would like to check out page 30 of the sample application (Customer Update Test tab) updating the surnames only, using credentials ja, demo, demo this is pretty much what I have got in my application.
Any ideas would be much appreciated?

Thanks for the suggestions guys. I have now identified that the problem goes away when I remove the second table from my report query. The original report query retrieved data from two tables and the process was updating only one of the tables. I thought I had approached the task logically i.e. first get the report to display the records from the two tables, then get the process to update the first table and finally to modify the process further to update the second table.
Can anyone point me to an example of multiple row updates on multiple tables using a PL/SQL function returning an SQL query?

It looks like the query string you are trying to pass back exceeds the 32K limit for a varchar. Where this is happening is kind of difficult to tell as it could be any number of points, and also depends on what you are passing into the process via page items.
I would first try to establish what combination of page items causes this error to occur. Then, starting from the bottom and working your way backwards, I would start 'switching off' some of the items you use to build your query until it breaks again, thus establishing which part is leading to the error.
Also, I'm not sure what :P10_STMT is doing (are you maybe using this for visiblity of the query created)?

PL/SQL function in datamodel query

Hi All,
I have the following problem:
I have a query Q1 returning a few rows. In the group G1 using this query Q1 i have a computed field returning a number NUM_1.
select col_1, col_2 from table_1;
So the output looks like:
row 1 col_1 col_2 NUM_1_1
row n col_1n col_2n NUM_1_n
I want to order these rows by the calculated column NUM_1 the highest first.
I know i can't order by a calculated column but can i do it by using a pl/sql function in the query to calculate the NUM_1?
Like:
select col_1, col_2, function(x) NUM_1 from table_1;
And where should i create this function? Can it be done in the program unit section or do i have to create a library?
Best regards,
Snoesky

Oke, i have created a break group on the calculated field.
Ordering works fine now.
I have an additional question:
Is it possible to dynamically order this break (column) group? Meaning thru a parameter to tell the ordering to be descending or ascending.
Regards,
Snoesky

Use of sql group function in orcl:query-database - urgent

All,
Version: 10.1.3.4
Two requirements for me:
1. I want to use sum function in orcl:query-database. How to use it?
For ex: I tried the following
<xsl:value-of select='orcl:query-database("select sum(salary) from emp",false(),false(),"jdbc/DB1")'/>
I got the following error
oracle.xml.sql.OracleXMLSQLException: Character ')' is not allowed in an XML tag name.
When I tried without sum function, it works fine
2. I used the same table, but without the sum function as below
<xsl:value-of select='orcl:query-database("select salary from emp",false(),false(),"jdbc/DB1")'/>
This time, it returns the first employees salary!! I dont understand this logic. I expected either the query returns all the rows else it throws error, but none of them were true!
Can anyone pls explain what is the behavior? I want your reply for both the queries!
Currently I'm in a project where I'm working in the similar scenario, so please guru's let me know ASAP.
Thanks,
Sen

Hi Sen,
Create a normal variable variable in XSLT.
Then use that variable.
I mean variable name='Var_1' select='Your Query'
Now use Var_1/yourcollection/...
I am giving some example
<xsl:variable name="Stopdetails" select="/ns0:MyEBM/ns0:DataArea/ns0:MyEBO/ns0:Stops/ns0:Stop[ns0:StopID=$TempStopId]"/>
<xsl:variable name="AccStopTypeVar">
<xsl:value-of select="$Stopdetails/ns0:StopType"/>
</xsl:variable>If you want you can loop on the created variable.
You can do these in XSL.
But DB calls those things ...it would be better , if u take them out. Spme debugging problems are there with XSL.

No, it is not true. Any function used in SQL is not allowed to perform a DML operation other than SELECT regardless if it is against the table that is being queried or not. Select is allowed against any table. And function in your example does INSERT which is not allowed. Also, Any function used in SQL is not allowed to perform commit/rollback/savepoint.
SY.
Edit: unless function is autonomous transaction.

BW User Exit - Code in function of the query name

Hi,
I would like to create an user exit code which execute a algorithm different in function of the query executed. do you know in which variable is store the technical name of the query.
CASE query
    WHEN 'Z_ZAPO_001'.
       V1 = 1
    WHEN 'Z_ZAPO_002'.
      V1 = 2    WHEN '10' OR '11' OR '12'.
ENDCASE.

Yaroslav,
I_S_RKB1D-COMPID will never be filled for authorization user-exits (I_STEP = 0). Don't ask my why, I once raised this question to OSS and they replied it was never foreseen to work with authorization user-exits. God knows why, it's very unlogical and it wouldn't cost them a lot of work to get it working...
I could solve this problem by applying a little trick. In our queries we included a user-exit keydate variable. This will push the user-exit first in I_STEP = 1 mode where I_S_RKB1D-COMPID is filled. Then save the query name by exporting it to the ABAP-memory. Afterwards, the user exit with code for I_STEP = 0 will be processed and then you can import the query name from the ABAP memory.
I agree it sounds a little bit tricky but there is no better option I'm affraid.

Using 'Function Returning SQL Query' with Flash charts

I have created a pl/sql function that returns a SQL query as a varchar2 of this form:
select null link
<x value> value
<Series1 y value> Series 1 Label
<Series2 y value> Series 2 Label
<Series3 y value> Series 3 Label
from tablea a
join tableb b
on a.col = b.col
order by <x value>
If I now call the function from a Flash Chart Series SQL box with the Query Source Type set to 'Function Returning SQL Query' like this:
return functionname(to_date('30-sep-2010', 'dd-mon-yyyy'))
it parses correctly and the page is saved; however, when I run the page I don't get any output - nor any error messages or other indication of a problem.
Now, if I call the function in a SQL client, capture the SQL query output using dbms_output and paste that into the Flash Chart Series SQL box - changing the Query Source Type to SQL Query - and save the page it works fine when I run it and returns a multi-series flash chart.
Can anyone suggest either;
1. What have I might have missed or done wrong?
2. Any way to usefully diagnose the problem...
I have tried using the Apex debugger - which is very nice, by the way - but it doesn't provide any info on what my problem might be. I even tried writing my own debug messages from my function using the apex_debug_message package - got nothing...
Thanks,
Eric

Hi Eric,
Try expressing the source as this:
begin
return functionname(to_date('30-sep-2010', 'dd-mon-yyyy'));
end;That works fine for me, and if I take out the begin-end and the trailing semicolon from the return statement I get the same behavior as you.
It does mention in the help for the source (only during the wizard though) that this source type has to be expressed that way, but I agree it would be helpful if the tool would validate for this format when 'Function Returning SQL Query' is used or give some sort of indication of the trouble. Anyway, this should get you going again.
Hope this helps,
John
