Call external function from SQL query
Hi,
I am new to PL/SQL programming.I don't think this is possible but please let me know if there is a way to achieve this. I have a function written in VB.net and I would want to call from the query.
create table temp as select id, callvbfunction(note_text) from temp2
Here callvbfunction is the vb.net function.I need to pass note_text field value to the function.
Thanks..
Yes it is possible.
No idea how to specifically call a .Net function (from Oracle) as I do not do Windows (except for playing games ;-) ). But external procedures (extproc) and Java stored procs can be wrapped by PL/SQL wrapper functions and used in SQL statements.

Calling the function from SQL query
Hi,
I am trying to run the below statement,
Select to_number(apps.pay_balance_pkg.get_value( 326, :paa.assignment_action_id,to_date ('31032011','ddmmyyyy'))) from dual;
getting an error as :
ORA-14552 cannot perform a DDL, commit or rollback inside a query or DML
ORA - 06512 at apps.pay_balance_pkg , line 4526.
How can I execute this funciton "apps.pay_balance_pkg.get_value" from sql query?

Thanks in advance.If the function is performing DDL, commit or rollback inside it then you will not be able to call it from an SQL statement.
Either change the function so it doesn't perform DDL, commit or rollback, or use a different means to obtain the information you want (assuming you can't change the function) -

How do you call a function?
nullJohn,
I think moifying the statement
CREATE OR REPLACE PROCEDURE "OGUSER"."OGX1" (user_county in integer, user_permit in integer )
TO
CREATE OR REPLACE FUNCTION "OGUSER"."OGX1" (user_county in integer, user_permit in integer ) return NUMBER is
AND before end you will have to add a return statement
(Probably
return 0;
exception
when others then
return 1;
end;
This will change your procedure to a function but I am not sure you'll be able to see your dbms_output's, if you call the function using select ...

Calling a function from SQL prompt that returns a record
Hi,
I've been trying to execute a function that is present on a different database. for eg. I am loged on to a database say 'A' and trying to execute a function present in database 'B'. this function is present in a package 'X' which has 2 functions and two procedures. From the packages i am able to execute the two procedures and one of the function.
So i guess it is not a problem with the access permissions. The function that i am trying to call say function I has got 3 OUT
parameters and 1 IN parameter. the Function returns a record. When i try to execute this function i get an error. Can you please let me know as to how exactly i need to call this function from the SQL prompt...
thanx in advance
nullHi Anand,
As your function has 3 OUT parameters and it returns a record you can not just call it from SQL Plus. You need to write small PL/SQL program and use variables to hold the OUT values and the returned record.
Good Luck,

Getting session hang When calling Function from SQL query
Hi All,
I am using Oracle 8.1.7.4.0. I have a fucntion in a Package and I am calling it from the SQL query. When I am firing the query my oracle session is going to hang position and I am not able to any thing. I have to kill the session.
But this same thing is working fine in Oracle 9.i.
There are no out parameter and no DML, DDL and DCL statement in this fucntion.
Could you please get back me what is the problem on it.
Regards
SUNCheck why your session hangs.
Just a few ideas:
* Blocking locks?
* Endless loop?
* Performance (maybe it is just slow in orac8i and you have to wait a bit longer). Check the execution plans of the SQL statements in your function.
* Don't use a function, but direct SQL, it is faster in both versions. -
Calling boolean function from tree query
Hi all,
I have placed a tree on my sidebar region from the following query
select PAGE_NO id,
PARENT_PAGE_NO pid,
NAME name,
'f?p=&APP_ID.:'||page_no||':&SESSION.' link,
null a1,
null a2
from #OWNER#.APEX_PAGES
WHERE page_no = :APP_PAGE_ID
AND nvl(navigation,'N') = 'Y'
Its running perfectly fine. Now i have my custom function "isUserAllowed(app_user, name_of_node, isParent)" which returns a boolean expression is the logged in User has access privilege on that node.
How can i run my function inside the tree query so that node is visible only for those values in which my function returns "true"? and not on others?
With Regards,
Sunil BhatiaThe "wrapper" function would actually be pretty easy - just another function to call the one returning the boolean and convert it to some other value, numeric or character. something like (untested)
<pre>
FUNCTION wrapper_function(P_whatever varchar2) return varchar2 IS
v_return_value_c varchar2(5);
BEGIN
r_return_value_c := case boolean_function(p_whatever)
when true then 'true'
else 'false;
return v_return_value_c;
END;
</pre>
Using the function in the WHERE clause could look something like this (untested, but should work if done correctly)
<pre>
select whatever
from your_table
where wrapper_function(whatever) = 'true'
</pre> -

Calling a function from SQL that has Out Parameters
Hello folks,
I am not sure if this is do-able, but here is my scenrio at hand. I have a database function that accepts a few IN parameters and OUT parameters. I want one of the Out parameters to display as part of my select statement. Is this possible?
ThanksNo you cannot use a function with out parameters in sql statements.
If possible make the function return that value, then use it in select.( imean instead of OUT parameter, get that OUT parameter through RETURN)

Calling a BOOLEAN returning function from SQL
Hello All,
I have created below function which return BOOLEAN value :
CREATE OR REPLACE FUNCTION FUNC_1
P_EMPID IN emp.empno%type
)RETURN BOOLEAN
AS
L_VAR NUMBER;
BEGIN
SELECT 1 INTO L_VAR
FROM EMP
WHERE EMPNO = P_EMPID;
IF L_VAR = 1 THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
END;Now I want to call this function from SELECT but I know that SQL does not support BOOLEAN value so I tried in other way i.e. via CASE
SELECT CASE FUNC_1(7788)
WHEN TRUE THEN 'TRUE'
WHEN FALSE THEN 'FALSE'
ELSE 'NULL'
END CASE
FROM DUALBut it is giving me error "ORA-00904: "FALSE": invalid identifier'
How can I achieve this ?
Thanks & Regards,
RakeshHi Rakesh,
Why cant you try something like this, When BOOLEAN type is not supported in SQL.
Here I have made the return value a number. And, at case comparison, we get the BOOLEAN
result as TRUE of FALSE.
CREATE OR REPLACE FUNCTION func_1 (p_empid IN emp.empno%TYPE)
RETURN NUMBER
AS
l_var NUMBER;
BEGIN
SELECT count(*)
INTO l_var
FROM emp
WHERE empno = p_empid;
IF l_var = 1
THEN
RETURN 1;
ELSE
RETURN 0;
END IF;
END;And,
SELECT CASE func_1 (55656)
WHEN 1
THEN 'TRUE'
WHEN 0
THEN 'FALSE'
END
FROM DUAL;Which return TRUE if the Employee Number Exists and FALSE if doesnot.
Thanks,

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

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,
EricHi 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

You have 2 types of calls. SQL and PL/SQL.
To call a function via SQL, it can be done using a the standard cursor interface. E.g.
select MyFunkyFunction from dualIt will return the function value via a single row with a single column. The standard cursor fetch and close cursor calls are used.
To call it via PL/SQL, an anonymous PL/SQL block is needed, and the caller needs to use a bind variable to receive the value from the function. The anon block will look as follows:
begin
:bindVar := MyFunkyFunction;
end;Refer to your client's abstract layer for interfacing with the Oracle Call Interface, on how to deal with bind variables. -

}Basically you just ignore the refcursor outbound parameter.
This is a stored function, have yet to try outbound refcursor parameters in stored procedures...

proj_budget_importance???????????
FROM project;
can someone show me please TA!!Your function is invalid:
proj_importance NUMBER (8,2);
BEGIN
IF p_budget > 250000 THEN
proj_importance := 'High';
ELSIF p_budget <250000 THEN
proj_importance := 'Normal';
END IF;
RETURN proj_importance;
END;
and never run :).
create or replace function proj_budget_importance
(p_budget in NUMBER)
RETURN VARCHAR2
IS proj_importance Varchar2(32);
BEGIN
IF p_budget > 250000 THEN
proj_importance := 'High';
ELSIF p_budget <250000 THEN
proj_importance := 'Normal';
END IF;
RETURN proj_importance;
END;
select proj_budget_importance(100000) from dual;
'Normal'
