Pro*C: Getting array of structs from a PL/SQL procedure

I am trying to create a stored procedure that will take the results of a select query, put them into an array of structures and send the entire array of structs back to the calling function in the C program.
I currently do a select into a cursor and return each row one at a time over the network.
Any syntax suggestions would be of help.

Getting at POST data from a pl/sql procedure through Path Aliasing

Hi.
I have mod_plsql configured with "path alias" and "path alias procedure" so that the request ends up in my
procedure and i have the remaining path in p_path. This is what I want.
http://<domain>/<dad>/<myalias>/<p_path>
My question is; is there a way at this point to get at POST data in the request? I haven't been able to find
any way of doing this looking through the documentation. Is the body of the request lost at the gateway
(mod_plsql) using path alias?
If so, is there some other way to achieve something like !myproc(name_array [somearr], value_arr [somearr])
where the first entry in the arrays is an eqvivalent to p_path?

My question is; is there a way at this point to get at POST data in the request? Do not understand the question as a POST and GET are simply two different methods that a web browser submits a URL and data. There is no "+path+" involved here.Thank you for answering. I think the confusion is because you disregard what I said about "path alias" and "path alias procedure".
Those are configuration of the mod_plsql gateway so that any URI containing <myalias> above is directed to the procedure stated
by "path alias procedure". The gateway also sends any remaining parts of the URI to this procedure as an varchar2 argument (p_path).
My problem is that I see no way to get at any POST data as the signature of this procedure has to be this one varchar2, and I don't
know any other way to get at the body of the request.
>

where the first entry in the arrays is an eqvivalent to p_path?If you want to know what the URL is, the full path used, then you need to look at the CGI (Command Gateway Interface) environment. The web server builds a list of CGI variables. These include the type of web server, the URL, the type of HTTP command (GET or POST), and so on.
Within your PL/SQL web procedure, you can query these CGI variables. Have a look at the function OWA_UTIL.GET_CGI_ENV in the [Oracle® Database PL/SQL Packages and Types Reference|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/w_util.htm#i997269] guide.
Take a look at CGI variables such as PATH_INFO, PATH_TRANSLATED, SCRIPT_NAME and so on.Yes, thank you, but my problem is a bit upside down. I do use the cgi environment to get the method and I have path as input, what I can't
find is the body of the request. I might be approaching this entirely the wrong way. It might be a bit easyer to understand if I state that I'm
trying to find a way to implement a RESTfull service in pl/sql.

How to get second maximum salary from employee table(sql query)

how to get second maximum salary from employee table(sql query)

dude there is no matter of structure .........that user already said its from employee table ...............its basic table in sql and there is no need to specify the table structure
.........i think u got my point I think you are the one who didn't understand Sarma's point.
Give a man a fish and you feed him once. Teach a man how to fish and you feed him a life long.
>
and the query is
select max(sal) from emp where sal<(select max(sal)
from emp);
this will give the 2nd max salary from the emp tableBtw: You solution is bad, because it needs to scan and sort the table emp twice. And a better solution has been given already.

Basic Report Run from a PL/SQL Procedure

I am hosed trying to start a BI Publisher report from a PL/SQL procedure. Basically, I have a procedure with a local variable defined as an XMLType. I need to call an RTF source, pass the xmlfile in and tell the RTF Engine where to send the output.
The users guide implies that it involves calls to a Java program and I am totally ignorant of Java.
I have successfully linked the RTF source into the XML_Publisher application and previewed it against a known data set. hat works.
So, if I have a PL/SQL package with the local variable L_XML defined as XMLTYPE
and an output file L_OUTBUT defined as VARCHAR2(100), what do I use to call the RTF Processor and generate the report to the output file?
That is
declare
l_xml xmltype;
l_output varchar2(100);
begin
-- stuff to build the xml variable
-- insert the call to FTP Processor here Apparently, it should be
-- something like
package.procedure('linked_rtf file name', l_xml, l_output);
end;
If this calls a Java script, would also appreciate a sample copy of the script.
My need is desperate so any assistance will be greatly appreciated.
Many thanks
Frank

I don't think you can. The parameters passed to a VB dll are formatted differently than a C dll, especially strings. I know a C program has to use special data structures when working with a VB dll, and this is basically what Oracle is doing.
It should be possible, however, to create a C dll that acts as a wrapper for the VB dll. I'm not sure this would save you anything, though. If you have to do that you may as well write the function in C.

Generating an xml from a pl/sql procedure

Hi Friends,
I have come up with a requirement to generate an xml from a pl/sql procedure.
I did some R & D and also got some sample procedures but could not understand the datatypes being used.
The procedure declares variables like this:
doc                  xmldom.DOMDocument;
mainNode         xmldom.DOMNode;
headerElem      xmldom.DOMElement; Pls could anyone tell what do these xmldom.DOMDocument, xmldom.DOMNode and xmldom.DOMElement mean?
Later in the procedure, these variables are assigned values like
doc      := xmldom.newDOMDocument;
mainNode := xmldom.makenode(doc); This went a bouncer on me.
Pls help.
Thanks in advance ...!

How to get multiple out parameters from a pl/sql stored procedure in ADF Jdeveloper 11g release2

I´m trying to call from AppModuleImpl a stored procedure from my oracle DB which receives one input parameter and returns 5 out parameters.
I´m using jdeveloper 11g release2 ADF and I have created a java bean "ProRecallPlatesBean " with the atributes and accesors and I serialize it. just like in this article http://docs.oracle.com/cd/E24382_01/web.1112/e16182/bcadvgen.htm#sm0297
This is my code so far:
public ProRecallPlatesBean getCallProRecallPlates(String numPlates) {
CallableStatement st = null;
try {
          // 1. Define the PL/SQL block for the statement to invoke
          String stmt = "begin CTS.Pk_PreIn.proRecallPlates(?,?,?,?,?,?); end;";
          // 2. Create the CallableStatement for the PL/SQL block
          st = getDBTransaction().createCallableStatement(stmt,0);
          // 3. Register the positions and types of the OUT parameters
          st.registerOutParameter(2,Types.VARCHAR);
st.registerOutParameter(3,Types.VARCHAR);
st.registerOutParameter(4,Types.VARCHAR);
st.registerOutParameter(5,Types.VARCHAR);
st.registerOutParameter(6,Types.VARCHAR);
// 4. Set the bind values of the IN parameters
st.setString(1,numPlates);
// 5. Execute the statement
st.executeUpdate();
// 6. Create a bean to hold the multiple return values
ProRecallPlatesBean result = new ProRecallPlatesBean();
// 7. Set values of properties using OUT params
result.setSpfVal(st.getString(2));
result.setTransportTypeVal(st.getString(3));
result.setTransportCompanyVal(st.getString(4));
result.setCompanyDescrVal(st.getString(5));
result.setDGAPrint(st.getString(6));
// 8. Return the result
return result;
} catch (SQLException e) {
throw new JboException(e);
} finally {
if (st != null) {
try {
// 9. Close the JDBC CallableStatement
st.close();
catch (SQLException e) {}
In Jdeveloper I went into AppModule.xml JAVA>Client Interface section and expose "getCallProRecallPlates" Then I can see "getCallProRecallPlates" in Data Controls, I drag and drop it to a JSF page, an input text component and a button are generated in order to put in there the procedure input parameter (numPlates).
I don't know if I'm on the right track.
When I click the button, the "result" variable is supposed to be filled with data from the stored procedure. I want each of those values to be displayed in Output text or input text adf components but I dont know how. Thank you very much in advance I´m a newbie and i'll appreciate your help!

Obtaining HTML page by issuing a call from a PL/SQL procedure

Maybe is necessary to initialize other parameters?
Any help?

How to download output from a PL/SQL Procedure

Hi all
I have set up a PL/SQL procedure that sets up the mime type etc.
to download the output but IE keeps telling me it can't get the
file. I think that it's something to do with the browser wanting
to just GET the file and getting extra stuff because the mime
header is being sent every time. Anyone managed to do this?
Code sample follows:
create or replace procedure x
is
begin
owa_util.mime_header('application/force-download',false,null);
htp.p('Content-Disposition: attachment;
filename="timeline.html"');
htp.p('Pragma: no-cache');
htp.p('Cache-Control: no-cache');
htp.p('Expires: Thu, 01 Jan 1970 12:00:00 GMT');
owa_util.http_header_close;
htp.p('<HTML>');
htp.p('<body>');
htp.p('Hello there man');

Get the report list in a PL/SQL procedure

Hi to all,
I need to get the list of the personal report of a specified user in a PL/SQL procedure, is this possible?
My procedure should delete not "standard" report of a specified portal user.
Then i must have the list of all user's reports and after do my delete logic.
Jhon Dhon

Jhon -
It sounds to me that what you want to do is have a list that is generated based upon the identification of an individual. You can do this a number of ways, but I think you would want to write a straight query to accomplish this rather than a PL/SQL procedure. A query to accomplish what you're looking to do would look something like this:
SELECT
person_name,
person_id_number,
other info you need to see in the output
FROM
table_name (that contains the info you need to see)
WHERE
conditional clauses to obtain only data you wish to see
AND :p_person_id = table_name.person_id_number
The AND clause line will return the employee the user wishes to see based upon that person's ID number. This information is asked for in a parameter form before the report is run. The :p_person_id is referred to as a bind variable. You can read more about this on Metalink or OTN.
HTH,

My question is a technical PL/SQL question related to Oracle Applications. I need to call a standard applications 'user exit' from a stored PL/SQL procedure. Can anyone tell me if this is possible and how to do it?
(i.e. I am attempting to call the AR user exit SALESTAX)
Thanks,

Creating a CSV file from a pl/sql procedure

Hi Everyone,
I would like to know how to write a procedure in pl/sql where i need to check if they are any records in a table say "Table A".
If they are any records in the "Table A" then we need to write those records in the "Table A" to the CSV file.
If they are no records then we need to insert a record into the CSV file that "No records are found in "Table A".
Could anybody please help ?
Thanks in advance

see this

2 p_dir in varchar2,
3 p_filename in varchar2 )
