Using a PL/SQL function in SQL

Hello
I wrote a function in pl/sql that create a table and return the name of the table as varchar2.
The function is AUTONOMOUS TRANSACTION.
I want to write a SQL that in the �FROM� section will call the function.
The SQL will take the name of the table (from the function) and recognize it as a table.
That way I can preform a join between the new table and other tables.
Do you know on a way to preform that?
I wrote the following SQL:
(assume the name of the function is � �New_table()� return varchar2 )
Select *
From (select �New_Table()� from dual) ;
This return the name of the table. But I want a SQL that will bring the data from the table
Apreciate your help

You say "I wrote a function in pl/sql that create a table and return the name of the table as varchar2.", now you want to select data from the newly created table in the same sql statement?
Although you could cobble something together in PL/SQL using EXECUTE IMMEDIATE, or in a sql script using several statements that would work, where will the data come from?
I'm guessing that you are populating the table in the function and are hoping to use it as something similar to a temp table in Sybase/SqlServer. If so, there are almost certainly several better ways to do this in Oracle.
Why don't you tell us what you are trying to accomplish by building a table in the FROM clause of a sql statement, and maybe someone can give a better solution.

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,
gina

Sergio, the codes are as followed,
Declare
q varchar2(32767); -- query
Begin
q := 'select "ID",'||
'"ENTRY NAME","TOTAL","#CM","%CM","#CA",'||
'"%CA", from Info_table';
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;
End;

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?

SQL Query(PL/SQL Function Returning SQL Query)

I am trying to write a dynamic report using SQL Query(PL/SQL Function Returning SQL Query).
I can get the report to run but I need to concatinate some columns into one, seperated by a comma or a dash.
I have tried select *****||','||***** alias
also select *****||'-'||***** alias
but I always get an error.
Is there a way of doing this please

This is my full query
declare

How to return less than 4000 characters from pl/sql function in SQL call?

Hello,
Is there a way to limit length for varchar when calling pl/sql function from SQL? No matter how I write it it always returns 4000 bytes.
If there is none, then does it make sense ever to specify lenght of the return variable?
My goal is to encapsulate business rules within pl/sql functions. But if all varchar columns are returned as 4000 it is not feasible solution. Not only this is a performance issue in a data warehousing environment, bet when using those rules within SQL views user experiance would suffer as well. Are we left with the rule hardcoding solution? Also, I think that using SUBSTRING or TRUNC functions on top of business rules function defeats the purpose.
Please see my attempt below. Your thoughts are appreciated.
Thank you.

Pointless,
Thanks for jumping in on this and I am glad you asked :).
I do not doubt that it is an architectural challenge. Otherwise it would have been done already! I am struggling with the fact that SQL knows what data type the function will return, but does not know the length of it, precision or scale. I will leave it at that.
I will go with some high level requirements to allow for alternative thoughts:
1)     Business defined rules. There are multiple types of business rules. Simple lookups, bucketing, complex calculations, data retrieved from other tables etc. We have about 500 different rules. Some of them are even overloaded – different inputs will produce the same output.
Some simple examples are:
Rule1 - Fruit
     when ‘A’ then ‘Apple’
     When ‘O’ then ‘Orange’
     Else ‘N/A’ end
Rule2 – Bonus
     when STATUS =’Active’ and LEVEL=’CEO’ then bonus=salary*1.0
     when STATUS =’Active’ and LEVEL=’nobody’ then bonus=salary*0.01
     else bonus=0
Rule 3 – Income Bracket
     When more than 0 and less or equal to 30000 then INC_B=’LOW’
     When more than 30000 and less of equal to 60000 then INC_B=’MIDDLE’
Etc.
2)     Challenge: All data users in an organization need to use the same rules (let’s assume data source is Oracle database). How to expose all the rules to different types of users in manageable way? Types of users – analysts, application/web developers, data warehouse teams etc.
3)     Current system: Not only each user has coded their own rules (luckily based on the common specification), but hard-coding is taking place for each query within the confines of one project. The project I just looked at had about 12 modules with 30 hardcoded queries. Oops! Few rules just changed.
My take: I was leaning toward encapsulating business logic within UDF’s. UDF’s provide all the flexibility we need + overloading. All the functions could be consumed by data warehouse team (building summary tables, cubes etc.) and application developers. For power users we could build views by applying the same functions on top of the source data. Thus avoid data duplication. It seemed win-win until this 4000 issue :).
Your thoughts on alternative approaches are appreciated.
Thank you.

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
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 source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
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.

APEX, BI Publisher and SQL Query (PL/SQL Function returning SQL Query)..

I don't know if I should be posting this in this Forum or the BI Publisher forum, so I am posting in BOTH forums..
I love APEX, let me say that first.. And appreciate the support offered here by the group, but am running int a confusing issue when BI Publisher tries to build a report from the above type APEX report..
Here is my dilemma:
I have a number of reports that are part of a Oracle package. They return an SQL Query back to a reports region on a page. I am having to deal with the column names returned are col01, col02..
The issue I have is, when building the Application Level query to download the XML sample from in building RTF layouts in Word, you can not use this code, you MUST use a standard SQL Select.
I have taken the sql from the function returning sql, and copied into the application query, supplying the required data values for bind variables being used in the query.
An XML file is produced, and I use this to build the RTF format file that I load back into APEX and try to use it for the PDF rendering of the report. I can view the output as a PDF in the Word add on, but when I try using it with the report, it is returning an empty PDF file.
Can anyone tell me what error log files on the bi publisher side I can look at to see what error is happening?
Thank you,

Title changed, maybe SOMEONE has an idea on this??

Hi,
1/ first check you are passing the bind variables and
appropriate values in the call to your report - if
the query returns no data then you get an empty page
So if your query takes :P10_USERNAME variable then
pass it to the report in the URL
f?p=&APP_ID.:0:&SESSION.:PRINT_REPORT=YOUR_REP_QUERY_N
AME:::P10_USERNAME:MYUSER
2/ try to use the Default layout first to check your
report query really returns the data when called
3/ if you defined a header in your rtf template check
there is no & (ampersand) - if using & in the header
and preview the template from word it displays data
OK, but if you use this template in the report query
it fails to render the data (bug in Apex-> Bi
Publisher integration maybe?)
4/ If using the table in the rtf template check its
width does not overflow the page margins - there is a
problem with pdf export
5/ check
/oc4j/j2ee/home/application-deployments/xmlpserver/app
lication.log forthe information on BI Publisher runs
RadoIssue was in the APEX page having issues.. I recoded a new page and am able to generate BI Publisher based PDF files..

Calling PL/SQL functions in SQL

Hi,
I had a question on the behaviour of PL/SQL function when they are embedded in SQL queries.
I have simple PL/SQl function:
function get_city_id
(vCUSTOMER_GROUP_ID IN NUMBER)
RETURN VARCHAR2 AS
vIDs VARCHAR2(1000);
begin
vIDs := '2,3';
RETURN vIDs;
end;
I use an SQL query call this PL SQL function;
select equipment_id from equipment where equipment_type_id in (get_city_id(0));
When I run this query I get this error:
ERROR at line 1:
ORA-01722: invalid number
I understand that the SQL compiler is complaining that get_city_id() function is not returning a number. but isn't the PL/SQL suppose to be replace with whatever string is returned from the function.
This brings me to the second question: How can we return multiple values from a function to the SQL query, when the function is called in a SQL query. In my above explame, can the get_city_id() function return more than one city id and if yes, the how?
Thanks for the help in advance
regards
Alankar

How can we return multiple values from a function to the SQL query,Have it return a collection, e.g.
CREATE OR REPLACE TYPE VARCHAR2_TT AS TABLE OF VARCHAR2(4000)
CREATE OR REPLACE FUNCTION test_collection
    RETURN VARCHAR2_TT
AS
BEGIN
    RETURN VARCHAR2_TT(1,2,3);
END;
SELECT *
FROM   employees
WHERE emp_id IN
       ( SELECT column_value
         FROM   TABLE(test_collection) );

Conditional display of region with PL/SQL function returning SQL query

Hello,
ApEx 2.0.
I use PL/SQL functions that return SQL queries to display the contents of a region.
How could I conditionally display such region ? If no data is found, the region shouldn't be shown. I tried with "SQL query returns at least one row" but this doesn't seem to work.
Thanks,
Matthias

Hi Matthias,
Are the regions in question report regions? So your PL/SQL process is returning a SQL query and then populating a report?
The EXISTS(SQL Query returns at least one row) condition should work, try running the query you are using in the Expression 1 textarea inside SQL*Plus, or SQL developer using the same parameters, and see what gets returned.
If you are still stuck, can you post the query you are using inside your Expression 1 textarea of the Conditions section and I can take a look at it for you.
Hope this helps,
Cj

How do I test sql function in sql*plus?

Hi,
I was given the syntax for a sql function and need to test this in SQL*Plus. What syntax do I use to test this?
p_UserName IN OUT SMUser.Name%type,p_PW IN OUT SMUser.
Password%type) RETURN INTEGER IS
nRet INTEGER :=1;
nCount NUMBER := 0;
BEGIN
select count(*) into nCount from smUser where smUser.Name = p_UserName
and smUser.Password = p_PW;
IF (nCount = 1) THEN
SELECT smUser.Name into p_UserName from smUser where smUser.Name =
p_UserName and smUser.Password = p_PW;
SELECT smUser.Password into p_PW from smUser where smUser.Name =
p_UserName and smUser.Password = p_PW;
RETURN 0;
END IF;
RETURN nRet;
END paulsoraclefunction;
Thanks,
Paul

This should work. You will need to make sure that the variables are declared as the same data type as in the function. Unfortunately, you cannot use %TYPE in declaring SQL*Plus variables.
VARIABLE p_username VARCHAR2(30);
VARIABLE p_pw VARCHAR2(30);
BEGIN
:p_username := 'PAUL';
END;
SELECT paulsoraclefunction(:p_username,:p_pw) FROM dual;
SELECT :p_username,:p_pw FROM dual;

During binding, strings are generally skipped. As such, you should first try replacing XMLType('?') with XMLType(?). You don't need to specify '?' because the system knows the proper type from your SQLBindParameter call.
Also, you should try replacing:
sr = SQLBindParameter(hstmt, 3, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_LONGVARCHAR, 0, 0,(SQLPOINTER)3, 0, &type[2]);
with
sr = SQLBindParameter(hstmt, 3, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_LONGVARCHAR, 0, 0,(SQLPOINTER)buf, BUFSIZE, &type[2]);

Sql function or sql procedure

I want to know if is better to use function or procedure for my problem.
First i need to read sql -> SELECT name, surname, date FROM ZKET_ZAPOSLENCI to get all data
When i get all data i need to use name and surname and change it with $name and $surname in some text.
Some text is:
Hello,
Worker $name $surname will be ...
Output must be:
Hello,
Worker Marco Kostrevc will be ..
and it must be inserted in database.
How can i make this?
regards

that you will not say that i am not doing anything
Code i try to make
create or replace procedure showcol (
statement in varchar2,
text_in in varchar2)
is
type cv_type is ref cursor;
cv cv_type;
val varchar2(32767);
procedure display_header_info ... end;
begin
/*construct the very dynamic query and open the cursor*/
open cv for || stavek;
loop
/*fetch the next row, and stop if no more rows*/
fetch cv into val;
exit when cv%notfound;
/*display the data, with a header before the first row*/
if cv$rowcount = 1
then
display_header_info(text_in, statement);
end if;
dbms_output.put_line (val);
end loop;
close cv; --al done clean up
end;
{code}
here i want to make replacement and return value (row by row) but do not how?

Creating PL/SQL function in SQL plus which will display desired output

Hello PL/SQL experts,
I am not skilled on PL/SQL so want you help for one of the PL/SQL requirement.
Requirement: We have a database purge jobs which deletes the records from our application database on daily basis. Our Client wants a verification PL/SQL to be created which they will run pre and post the purge job to identify the number of records deleted/processed by purge job. It should do a SELECT operation and find out the number of records in table based on the where clause and give the output to the user.
The result of PL/SQL should be something like this (considering the PL/SQL is processing multiple select statements):
****Verification SQL Start*****
30 records from table S_SRV_REQUEST selected
45 records from table S_SRV_REQUEST_X selected
15 records from table S_SRV_REQUEST_XM selected
*****Verification SQL complete*****
For this I am thinking of a simple PL/SQL which will diplay the count of records from each table but I am not sure how to display the count on screen as an output. Can I request PL/SQL experts to put some light on this?
Regards
Sumit

PL/SQL is a server side process running on your database server. It is not connected to a display or a keyboard, so cannot output any results from within the code itself.
What you need is a client application that the user can run which will query the database, or call procedure(s) to get results and then the client application will display those results appropriately.
One of the simplest client tools you can use to build such a user-friendly application is Oracle Application Express (APEX).
Bear in mind that if you're going to 'identify' record for deletion prior to actually deleting them, then you may also have a need to store the keys of those identified records somewhere so that only those records are deleted. Consider the situation where the user requests the information and the application queries the records to say there are 30 records from S_SRV_REQUEST with the correct criteria to be deleted. By the time the user confirms they are happy and want the records deleted, some other record(s) may have been updated and also meet the criteria, so just doing a delete based on the criteria itself could result in more than 30 records being deleted. However if you've identified the records and marked them in some way for deletion or stored the keys of those records on a queue somewhere to indicate the ones to be deleted, then your actual deletion process can just deal with those records and ignore any that have met the criteria since that time. Of course that depends on your individual requirements, but it's something to bear in mind.

Sql functions with SQL*loader

For the testing purpose I created table
SQL> desc test
Name Null? Type
C1 VARCHAR2(20)
A file test.txt contains only one record:
12/13/2007-09/15/2008
control file contains:
load data
infile 'c:\grum\test\test.txt' "str '|'"
insert into table test
(c1 "substr(:c1,1,10)" )
After performing Load
SQL> select * from test;
C1
1
I am unable to understand the value in the table should be:12/13/2007
Can anybody help me please

Try:
(c1 position(1:10) )

SQL Query problem (PL/SQL function returning SQl query)

END IF;
RETURN l_sql;
END;
The query returns data.
If I add some more code just after the where clause.
AND decode(CUST_CODE,'TW','TW','RET') like (select decode(OPS_SEP,'TS','%',OPS_SEP) from T_U_CDW_BU_OP_SEP where upper(USER_ID) = upper(:APP_USER))
The query just stops working and no error message is returned.
I thought there was an issue prior to version 3.1.2 that was fixed in version 3.1.2
Othwerwise is there a better way to write the code? As I have 7 radio btn's that control the condition within the where clause.
Thanks
Ron

Are you sure?
Do as Paul has suggested and post the code that doesn't work (including your extra line) using the {noformat}{noformat} tags +exactly+ as you had it in the region source.
Cheers
Ben
