Call javascript functions from PL/SQL

Hi !
I just want to know if it is possible to call a javascript function from a PL/SQL procedure. If yes, anybody can explain me the syntax ?
Thanks
Chantale

You can call Java Script - kind of.
PL/SQL has a "web browser" called UTL_HTTP. It allows you to make HTTP calls to a web server. This includes a function that can be used from SQL too (with a size limitation).
Example:
SQL> select UTL_HTTP.Request( 'http://some-web-server' ) as HTML_PAGE from dual;
HTML_PAGE
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<META HTTP-EQUIV="Refresh" CONTENT="1;URL=http:/some-web-server:7777/index">
<html xmlns="http://www.w3.org/1999/xhtml">
<img src="images/Wave.gif">
Redirecting.. please standby..
<hr>
</html>
SQL>The call to the web browser can be to execute and load, for example, a JSP page.
However, if the page containts client-side Java script, i.e. code for the web browser to execute, than UTL_HTTP will merely return the contents & code of that page.
Client-side Java Script requires an engine in the browser. The JS language is used to manipulate the rendering engine of the browser.
The PL/SQL "web browser" does not have a display device to show a web page. Thus it is without a web browser rendering engine and therefore also cannot execute Java Script either.

Hi Dinesh, Thanks for the response!
I've also tried doing the following without success:
DECLARE
   v_name APPLICANTS.NAME%Type;

BEGIN
   select name, surname

i'm trying to call an oracle query-function from ejb3.
The oracle function:
create or replace FUNCTION getSecThreadCount(secId in NUMBER,avai in NUMBER)
RETURN SYS_REFCURSOR is cur SYS_REFCURSOR;
m_sql VARCHAR2(250);
BEGIN
m_sql:='select count(thrId) from thread where secId='|| secid||'

1. the calling code:

          Query query=manager.createNativeQuery("{call getSecThreadCount(?,?) }");
          query.setParameter(1, secId);

but i got the exception:

By the way, i have successfully called the function from hibernate. And i use oracle 11g, JBoss5 RC1.
Could anyone tell me how to call the function from EJB3?
Thanks.

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

How to call a function from asp

Hi!, I'd like to know how to call a function from an asp page. I've written:
set rs = server.createobject("Adodb.recordset")
rs.open "call dbo.sf_Obt_Des_Producto ('0000161')",Conn
if err.description <> "" then
response.write ("No se pudo! :(")
else
response.write ("rs: " & rs(0))
end if
rs.close
set rs = nothing
but there is an error:
ORA-06576: not a valid function or procedure name
Please is very urgent!!!
Thanks.
Angie.

You need to use the syntax "{call <procedure_name>}".
The {call } syntax tells the OLE DB provider that it needs to translate the call into whatever the database's procedure calling syntax is. This means that even though different databases have different syntax for calling stored procedures, your OLE DB code can be run against any of them without changing.

Calling javascript function from report customization form

I have been unable to call any user-defined javascript function from Portal Report Customization forms.
Even a simple Message Box function doesn't work. I've been placing my code in the ..after header PL/SQL section for the report customization form.
htp.p('<script type="javascript">');
htp.p('function MsgBox(message){');
htp.p('alert(message);}');
htp.p('</script>');
htp.p('See if it works');
I have verified in plain html that my syntax is fine. Even the syntax rendered by portal is correct:
<script type="javascript">
function MsgBox(message){
alert(message);}
</script>
See if it works
Despite this, you will get a javascript error that an Object is expected, MsgBox not defined. Clearly from the script above MsgBox is defined.
I have tried any number of calls to user defined functions and can't get anything to work. However, calling native functions like 'alert' works fine ( ie
See if it works
Anyone know how I can call a user defined javascript function in a Portal Report Customization form?

Try changing the code
htp.p('<script type="javascript">');
to
htp.p('<script language="javascript">');
Thanks

How to call a function with pl/sql

How does one call a function with pl/sql that uses a function?

Hi,
How does one call a function with pl/sql that uses a
function?I'm not sure what you mean.
In PL/SQL function can be used just about anywhere where an expression (with the same data type that the function returns). Arpit gave a very common example.
Here's another example, where all the functions take a single NUMBER argument and return a NUMBER, so they can all be used in places where NUMBERs are used:
IF fun_a (fun_b (0)) < fun_c (1)
THEN
    UPDATE table_x
    SET     column_y = fun_d (2)
    WHERE   column_z = fun_e (ROUND ((fun_f (3), fun_g (4)));You call a function simply by using its name, followed by its argument list, if any.
If the function is in a package, you must call it with the package name, like "pk_foo.bar (1, 2, 3)", unless the call comes from within the same package.
If the function is owned by someone else, you must give the owner name, like "scott.bar (SYSDATE)" or "scott.pk_foo.bar (1, 2, 3)". You can create synonyms to avoid having to name the owner.
