call the XMLQuery pl sql function

Hi all.
Is anyone know how to call the function sql pl by XMLQuery query?

For example:

I pl sql function "test()".

And the desire to write this way:

Select XMLQuery (' let $t = test()' returning content);

How to change to work?

Thanks for all the answers.
Kind regards
Anton.

following should give you an idea:

SQL> select xmlquery(('if (2*2 = ' || power(2,2) || ') then 1 else ()') returning content) x from dual

X
-----
1
1 row selected.

call the collection of sql
Hello guys,.

I just wonder can I get the SQL collection via PL/SQL. However, I can't call from pure SQL. In other words,.
```
create or replace type plch_number is table of number;

create or replace package den 
is

  my_arr plch_number := plch_number();
  procedure doldur(a pls_integer);
  function func2 return plch_number;

end;

create or replace
package body den 
is

procedure doldur(a pls_integer)
is
begin
  my_arr.extend(a);
  for i in 1..a
  loop
    my_arr(i) := i;
  end loop;
end;


function func2 return plch_number 
is
begin
  return my_arr;
end;

end;
```
I can run the following code without any errors.
```
set serveroutput on;
declare
  a integer;
begin
  den.doldur(10);
  select count(*) into a from table(den.my_arr);
  dbms_output.put_line(a);
end;


------------------------------------------
anonymous block completed
10
```
However, when run the code sql. Although it is almost the same code that I have run PL/SQL block, it gives an error, ORA-06553: PLS-221.
```
select * from table(den.my_arr);
ORA-06553: PLS-221
```
In addition, I can call the function from the package through SQL without any error. But why I can't invoke collections directly from SQL, why?
```
select * from table(den.func2);
```
Thank you.

OK, but I just want to know, why? I mean, is there a technical explanation?

Unfortunately, in ORACLE SQL & PL/SQL keep two separate motors. All SQL allows you to call is UDF (user-defined functions). You can't call procedures in SQL and you cannot reference package variables. Everything works and even this is not always possible - for example, you cannot call a UDF with OUT or IN OUT. You cannot call function PL/SQL defined parameter and return value types.

How to call the OFA PL/SQL procedure.
Hello

I'll call the pl/sql stored procedure of the OAF page (AM). the procedure is content parameter 3 IN 1 OUT parameter. all the parameters of character type is integer.

I put the output parameter and it's returning the value, but I don't have how to configure the setting IN because the settings IN, I need to convert the INT data type number in java.

Please help me.

I would tell you to go through the "appeal of PL/SQL procedures and functions" Section in the User Guide.
Example and the details are there reference.

How to get the query of the region "PL/SQL function body returns the query string"?
Hello

is it possible to get the query string from the region of type "PL/SQL function body returns the query string"?

I can get the definition of the region as a PL/SQL procedure, but I am interested in the returned query. I tried to write something like

< pre > v_return_query: = «...» » ;
: P49_QUERY: = v_return_query;
Return v_return_query; < / pre >

to save the return on hidden item P49_QUERY string, but it does not work. I get the error message: ERR-1002 cannot find the item for the "P49_QUERY" element ID in the application '4000 '.

Kind regards
Przemek
If you need to make reference to a page element in the block then you can use this type of control to avoid having to use generic column names:
```
if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then-- runtime  :P9_SQL := vSQL;else-- design time  null;end if;
```
But if all you want to do is capture the SQL debugging you can take all the references element in the block and use the insert statement (in a debug table) as I showed earlier.

ORA-900 sql not valid reporting error while calling the optimize_index pl/sql procedure

Hi Experts,

I'm on Oracle 11.2.0.3 on Linux and I have installed in my database Oracle text. I want to configure annex dbms_job to optimize my oracle text index. So first, I created a pl/sql procedure to optimize indexes. It gives me error ORA-900, but the sql even if I run in sqlplus works very well! Can you please help me the question is to find:

Here is the procedure:

(Either incidentally CTXAPP role has been granted in the schema where these Oracle text indexes are created and where the below procedure to optimize the index is running.)

CREATE OR REPLACE PROCEDURE optimize_ora_txt_indexes_debug
IS
   CURSOR cur_context_indexes

          FROM user_indexes

        v_sql:= 'ctx_ddl.optimize_index (idx_name =>'||chr(39)|| c.index_name||chr(39)||', optlevel => '||chr(39)||'FULL'||chr(39)||')';
        dbms_output.put_line(v_sql);

            v_error_msg := SQLERRM;
            v_msg :=

 --the procedure compiles successfully. 
 Now when I run it , I get the error:

ctx_ddl.optimize_index (idx_name =>'ACCESS_CLNT_IDX04', optlevel => 'FULL')
Error while optimizing the index ACCESS_CLNT_IDX04 -900 ORA-00900: invalid SQL

 --When I run the same command from sqlplus as execute statement , it works fine:
SQL>exec ctx_ddl.optimize_index (idx_name =>'ACCESS_CLNT_IDX04', optlevel => 'FULL');
PL/SQL procedure successfully completed.

If everything runs from sqlplus, but fails in plsql... I'll be very grateful for pointers solve the problem.

Thanks,

OrauserN

Hello

It is a problem of pl/sql syntax. A call with EXEC is the same using BEGIN... Code of... END of block;

SO, you need to include a beginning and an end to your call:

 v_sql:= 'BEGIN ctx_ddl.optimize_index (idx_name =>'||chr(39)|| c.index_name||chr(39)||', optlevel => '||chr(39)||'FULL'||chr(39)||'); END;';

That's all.

Call the Flash of IE10 function

Hey guys,.
So, I'm looking to have some javascript call a flash function. I have it fully functional with older versions of IE, as IE9. However IE10 won't.
I followed the example provided by Adobe here: http://help.Adobe.com/en_US/FlashPlatform/reference/ActionScript/3/Flash/external/external Interface.html #addCallback ()
Using this code example, (in IE10) I'm successfully able to send data to flash on my Javascript, but coming from the other direction, it does not work.
The error I get is (' object does not support property or method 'methodNameHere' ")
Does anyone have ideas of what I could use to do? Or IE10 does not support this communication longer? Any thoughts are appreciated, thank you!

ExternalInterface.call("saveglobalscore",score), as you know, is easy to implement.

ExternalInterface.addCallback("IsStatic",IsStatic) is must more difficult because he has not a lot of flexibility in the HTML, code integration.

in your embed code, you (try to) embed a swf file that is named ExternalInterfaceExample.swf. If the SWF with your method addCallback test.swf, it's a problem.

you need to change one or the other.

Call the allocation of memory function of library

Hello

I want to call a dll of LabVIEW and one of the entries expects a pointer to double (double *). I did things like that before and use create table to allocate memory in LabVIEW to pass to the dll. This time what is expected is a pointer to a unique double. Can I just wire a double digital scheme at the entrance or it will not really affect memory?

~~It would be preferable to wire a single instead of a double, but other than that~~ (Oops, misread "double single" as "single"), Yes, it will correctly allocate memory. You just configure the parameter as a double ~~single~~ from pointer.

PL/SQL function to calculate the non-working days

Hello
I have the following pl/sql function which generates a number of days between two selected dates (i.e. excluding weekends). However, I also need to exclude specific holidays - day of Christmas etc. These holiday dates are stored in a table in our database (11 GR 2) called "HOLIDAY".
How can I integrate the holidays which is held in the table of holidays in the following query to exclude these dates as well? I know how to write a separate funtion pl/sql for a number of days between two dates using SELECT... BUT I can't work out how to bring together them in a single query.
Could someone show me how with the pl/sql / dates below please?
Example of HOLIDAY table below.
Thank you!

Hi Frank,.

In a procedure, you can use BACK (it's only for functions). For an application process, use htp.p (answer1) and get this response in the Javascript code that you use to call this process.

Can someone help me how to call...
Call it in function, not as a procedure you do
```
try {
String stmt =
"begin :1 := XXWFS_SANCTIONS_PKG.CHECK_SANCTION(:2,:3,:4,:5,:6,:7,:8,:9,:10,:11,:12); end;";
st = getDBTransaction().createCallableStatement(stmt, 0);
st.registerOutParameter(1, Types.VARCHAR);
st.setNull(2, Types.VARCHAR);
st.setNull(3, Types.NUMERIC);
st.setObject(4, customerID);
st.setNull(5, Types.NUMERIC);
st.setNull(6, Types.NUMERIC);
st.setObject(7, locationID);
st.setNull(8, Types.NUMERIC);
st.setNull(9, Types.NUMERIC);
st.setObject(10, tail);
st.setObject(11, tailNum);
st.setObject(12, result);
st.execute();
 = st.getString(1);
```

PL/SQL anonymous block - try to call the function within cursor
Hello-

I need to create an anonymous block that contains a cursor and function. I want to call the function from the cursor and function will essentially have an ID as parameter and will return a list of values comma separated.

However, when I try to do it I get the error 'function 'GET_PAYMENT_DATES' is not usable in SQL.

Does anyone know of a workaround? I'm trying to avoid having to store this function.

Thank you
Christine
Well you can't do this using an sql not stored function.
What you could do is to increase your sort_area_size which can help you to overcome the performance Bug.

for example: alter session set sort_area_size = 64000;

other than that, it seems that you need a stored function

Call the function browser plsql (403 error)

Hello
I m pl/sql developer and I m new in APEX. In fact, I have little trouble with Express application, authorization and call browser plsql. I found the pl/sql procedure to see the image (actually I don't like in pl/sql, I'll be happy if I calll Hello World of browser).
My Info: Oracle 12.1 c, Windows 7, default APEX 4.2
I found it is appeal possible function of the url in this way: http://localhost:8080/apex/APEX_040200.just_print and he return 403 for me, where:
Just_print is defined as
```
create or replace
PROCEDURE JUST_PRINT AS
BEGIN
htp.p('HAF');
END;
```
Just_print, it's in the APEX_040200 scheme
According to web articles that I give perform this function ANONYMOUS or APEX_PUBLIC_USER or PUBLIC. I don't like the safety (my local host, learning...) so I have him granted for all:
```
grant execute on just_print to anonymous,apex_public_user,public;
```
It must stop return 404 (not found) and start to return a 403 (forbidden) - it works (for anonymous scholarship, but I hold decided run grant for all accounts - just for sure)
Now, according to web I must change the function wwv_flow_epg_include_mod_local (in the APEX_040200 schema) and add the name of function. I tried but doesn't work. Yes, there is first line of the procedure returns alwas FAKE and I remove it, I also added the procedure IN the list. And also modified function that simply returns TRUE. Nothing works, real version is:
```
create or replace 
function                                     wwv_flow_epg_include_mod_local(
    procedure_name in varchar2)
return boolean
is
begin
    if upper(procedure_name) like '%PRINT%' or upper(procedure_name) like '%IMAGE%' then
        return TRUE;
    else
        return FALSE;
    end if;
end wwv_flow_epg_include_mod_local;
```
(u just removed comments to be the shortest). Here it's like printing (the function) and image (feature first tried) and superior, also when I try this:
```
begin
if apex_040200.wwv_flow_epg_include_mod_local('just_print') then 
 dbms_output.put_line('OK'); 
 else dbms_output.put_line('FAIL');
 end if;
end;
```
It will print OK (and also for ctrl + c/ctrl + v in web broswer) and also for any changes - APEX_040200.JUST_PRINT etc so it should not be a typo error.
When I call just_print or PL/SQL region show_image (create page - add plsql - region and add the code begin just_print; end ;) it works.)
Also, I've run the instalation guide ACL policy (all).
I not found any other step to must be done - so I don't have anything else.
--
Any suggestion what I am doing wrong? (except the whole life, but this is another story...) )
THANK YOU VERY MUCH

Hello

I don't think it's your problem, but it's bad idea create procedures to the diagrams of the system as APEX_040200.

Create procedure to the own schema and then create public synonym for it.

Grant execute privilege to public for the procedure, just to test.

And change 040200.wwv_flow_epg_include_mod_local function always returns true, just to test
```
create or replace
function wwv_flow_epg_include_mod_local(
    procedure_name in varchar2
) return boolean
is
begin
  return FALSE;
end wwv_flow_epg_include_mod_local;
```
Then try the URL http://localhost: 8080/apex/just_print

Kind regards

How I did wrong?
Thanks a lot for your help

The error means generally that your external procedure (process c in this case), failed or crashed.

The details of the Oracle error:

28576, 00000, "loss of the RPC connection to the external procedure agent."
* Cause: A fatal error occurred either a RPC network connection.
agent extproc or the invoked 3GL after disclosure
was created successfully.
* Action: First check the 3GL code you are calling; the most likely
This error is an abnormal termination of the
called 'C' routine. If this is not the case, look for
network problems. Correct the problem if you find. If all the
components appear normal, but the problem persists, the
problem could be an internal logic error in the transfer of the CPP
code. Contact your customer support representative.

Probably the dynamic loader used by the kernel to resolve external dependencies than physical of the executable failed?

Mike Board solves the problem? IMO, it should...

As a general rule, simply declare the or - prefixes or by default - you need resolve the XPath expression.

Once you correct this part, you will discover that your query returns null.

This is because the XPath expression is not point to any node.

Try this instead:
