Calling : sql functions

Hi
I have a question. If I open a connection and call an sql function n number of times in a loop and then commit and close the connection, does it involve n number of database hits? is it very expensive in terms of time taken?(But, functions are precompiled I guess, so it should not take much time), any suggestions...
Thanks
Gaurav

does it involve n number of database hits?Yes. Or, depending on how you define "database hit", it may involve even more if the function does several SQL operations.
is it very expensive in terms of time taken?Depends on the function. N times as expensive as calling it once. If the function doesn't do anything complicated, you may be able to call it several hundred times a second. Try it to see how long it takes.

Can we call sql function in java

as i know i can call stored procedures ,but can i call pl/sql functions.

Using JDBC you can execute any valid sql statement.
For a pl/sql function you use a CallableStatement and the syntax:
{?= call <procedure-name>[<arg1>,<arg2>, ...]}

Hi There,
I am trying to execute INSERT INTO XML_DATA (NAME, DATASIZE, DATA) VALUES (?,?,XMLType('?')) using ODBC C
SQLBindParameter APIs.
If I execute the INSERT INTO XML_DATA (NAME, DATASIZE, DATA) VALUES (?,?,XMLType('<name>milind</name>')) works fine.
Can anybody please help me out here?
Thanks,

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]);

How to call a SQL function from an XSL expression

Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :
1) How to call a SQL function from an XSL expression that is allowed in BI template.
If anyone ahs faced similar requirements please share your approach.
Thanks
Srimathi

Thank u..
but i'd seen that link wen i searched in google..
Is it possible without using any 3rd party JARs and all?
and more importantly plz tell me what should be preferred way to call a javascript function?
Do it using addLoadEvent() or Windows.Load etc
OR
Call it thru Xsl? (I donno how to do dis)
Thanks in Advance..

SQL report region source to call a pl/sql function using DB link

Hi - I have a pl/sql function fn_dbtype(id NUMBER) defined in database X. The pl/sql function executes couple DML statements and returns a string (a SELECT query). I am able to call this function using SQL Plus (Connected to Database X) as below and it works fine:
declare
vSQL VARCHAR2(100);
begin
vSQL := fn_dbtype(1);
end;
The DML operations completed fine and vSQL contains the "Select" query now.
In APEX:
I am trying to create a SQL report in APEX using SQL query(PL/SQL function returning a sql statement) option. I am trying to figure out what to put in the region source so that the output of the "Select" query is displayed in the report.
Moreover APEX is hosted in a different database instance. So I would need to call this pl/sql function using a DB Link.
Please let me know what I need to put in the region source to execute the pl/sql function which returns the "Select" query thereby displaying the query output in the report. Thanks.

Passing parameters to PL/SQL function called in VO

Hi,
I am writing a VO that is calling a PL/SQL function. The VO query looks like this.
select xx_dummy_func (:1,:2) from dual
Now, how can I assign these two parameter values at run time?
Generally when we have a query parameters We do xxVO.setwhereclauseparam. But in the above scenario, its not a whereclause but instead a procedure parameter. Please let me know how to do it.
Thanks in advance,
Regards,
-Abm

Thats correct, basically, setwherecaluse param api, just replaces bind variables with the index values, whereever they are in the query!

For each row of a table call a pl/sql function

Hi,
i have a search form in adf like this:
parameter1:___
parameter2:____
buttonSearch
Table with results
field1 field2 field3
row1 ------ --------- -------
row2 ------ --------- -------
row3 ------ --------- -------
The user inputs the parameters 1 and 2 then press buttonSearch and the query execute and returns rows 1 to 3.
What i need is for each row call pl/sql function and passed the parameter 1 and 2 and field 1 to 3 (plsql function recives 5 parameters (parameter1, parameter2, field1 , field2 and field3) )
my buttonSearch call a java class that execute ExecuteWithParamters method.
I create the call to my plsql function on Application module class and then export as a java interface.
So i have the function to use in the viewcontroller layer, but i don't know where to use it, and how to pass the paramters: the parameter 1 and 2 that user inputs and the row fields.....
any ideas....
thanks!!

Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.
Frank
Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do

SQL query slow with call to function

I have a SQL query that will return in less than a second or two with a function in-line selected in the "from" clause of the statement. As soon as I select that returned value in the SQL statement, the statement takes from anywhere from 2 to 5 minutes to return. Here is a simplified sample from the statement:
This statement returns in a second or 2.
select A.pk_id
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
if I add this function call in, the statement runs extremely poor.
select A.pk_id,
II.ytd_unx
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
Here is the function that is called:
create or replace FUNCTION calc_ytd_class_abs2 (p_fk_stu_schedule in varchar2,
p_legality in varchar2) return number IS
l_days_absent number := 0;
CURSOR get_class_abs IS
select (select nvl(max(D.days_absent),'0')
from cut_code D
where D.pk_id = C.fk_cut_code
and (D.legality = p_legality
or p_legality = '%')) days_absent
from stu_schedule_detail B, stu_class_attendance C
where B.fk_stu_schedule = p_fk_stu_schedule
and C.fk_stu_schedule_detail = B.pk_id;
BEGIN
FOR x in get_class_abs LOOP
l_days_absent := l_days_absent + x.days_absent;
END LOOP;
return (l_days_absent);
END calc_ytd_class_abs2;

Query returns anywhere from 6000 to 32000 rows. For each of those rows a parameter is passed in to 4 different functions to get ytd totals. When I call the functions in the in-line view but do not select from them in the main SQL, the report (oh, this is Application Express 4.0 interactive reports, just an FYI) runs fast. The report comes back in a few seconds. But when I select from the in-line view to display those ytd totals, the report runs extremely slow. I know there are the articles about context switching and how mixing SQL with PL/SQL performs poorly. So I tried a pipeline table function where the function for the ytd totals populate the columns of the pipeline table and I select from the pipeline table in the SQL query in the interactive report. That seemed to perform a little worse from what I can tell.
Thanks for any help you can offer.

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) );

Calling a PL/SQL function in the SQL statement

I have a PL/SQL function which i should call in a SQL statement.
Let's say the function is func1(parameter1,parameter2),
it should be called like this :- SELECT func1() FROM mytable ;
Can any one help me out on this ?
---Thanx in advance

you can call pl/sql functions from pl/sql using
select fn1('param1','param2') from table;
if you dont want to pass paramters, you have to specify default
value while creating function like below
create function fn1(p1 number default null,p2 varchar2 default
null) return...
now you can call using
select fn1 from table;

Calling JS function in pl/sql process

Hello!
I have a js function defined in 'HTML Header' :
<script language="JavaScript" type="text/javascript">
function disp_alert()
alert("Data is invalid! Correct the data and click CONFIRM again.")
</script>
I also have a pl/sql process on this page. I want to call disp_alert function in a following way:
if ... then call function
else dbms_output.put_line('...');
end if;
How can I call this js function in 'if'??
Tom

There ARE ways to accomplish something like this, but they're much more complex.
You must create a JavaScript that uses APEX's built in AJAX components; a form button will call the JavaScript, which will in turn call a PL/SQL procedure saved as an "On Demance Shared Application Process." This procedure can run any checks you like against the DB, and return data to the Javascript to display in an alert.
You can see an example of this in use at an APEX page I created: http://htmldb.oracle.com/pls/otn/f?p=19864:5
This isn't the same thing, but is accomplishing what it does through an APEX form, a javascript call on the text field to a PL/SQL Process that returns rows from the database dynamically...thus allowing the client side JavaScript to call server side PL/SQL.

Calling pl/sql function in CKM...pls help

Hi,
I have made a call to PL/SQL function in CKM customization. The code is :
declare
L_PMG_VALUE VARCHAR(3);
begin
L_PMG_VALUE:='PMG';
VALIDATE_PMG_VALUE(L_PMG_VALUE);
end;
When i run it, it throws error which says:

PLS-00221: 'VALIDATE_PMG_VALUE' is not a procedure or is undefined
ORA-06550: line 1, column 64:
PL/SQL: Statement ignored
Function is compiled in the database and its working. I have selected the Technology as Oracle and correct Schema Name.
Please help

Hi,
try the following way. i have not tried ....i think it helps you.
In which schema you have created that procedure.
Does the ODI user mantioned in topology have execute permissions on the procedure? if the ODI user have execute previlage on the procedure then in CKM customisation call the procedure like <schema>.<procedure>.
Please let me know any issues.
Thanks,

Can I call a function with an arguement of %ROWTYPE directly from SQL?

I have the following function in a 10g DB:
CREATE OR REPLACE FUNCTION f_is_eligible2 (in_dm_row IN amplify_dm%ROWTYPE)
RETURN NUMBER
IS
I know I can call that function from another pl/sql function but I'm wondering if I can call that function directly from a SQL statement, something like this:
SELECT f_is_eligible2(dm.*)
FROM amplify_dm dm
or
SELECT f_is_eligible2(dm%rowtype)
FROM amplify_dm dm
neither of those worked so I'm thinking it's not possible but I thought I'd ask anyway.
Thanks in advance!

Not possible as said - but - based on what I'm seeing - you could simply pass the parameter(s) that are key on that table and - accomplish the same thing by modifying the function.
not sure why you'd need the whole row if I'm interpretting the code excerpt.
