Passing pl/sql array to function

Hi,
I have a function which takes an array:
create or replace
FUNCTION execute_tests(
leg_keys IN type_leg_key_array)
RETURN BOOLEAN
IS
BEGIN
leg_key_array is this:
create or replace
TYPE type_leg_key_array AS TABLE OF NUMBER(6, 3);
I would like to test this funtion by passing it some array:
DECLARE
LEG_KEYS DEV_SWA30PRE.TYPE_LEG_KEY_ARRAY;
V_RETURN BOOLEAN;
BEGIN
-- LEG_KEYS := NULL;
v_Return := EXECUTE_TESTS(LEG_KEYS);
END;
What is wrong with the snippet above?
Thanks

What is wrong with the snippet above?Why do you think anything is wrong? Are you getting an error message? Post the complete error message, including line numbers. Does the error occur when you create the type, when you create the function, when you call the function, or someplace else?
The only errors I see are probably due to how you chose to post it. For example, there is no RETURN or END statement in execute_tests.
Did you create the type before trying to use it in the function?
What is DEV_SWA30PRE? Is that a schema? Does that schema also contain the fucntion? Is that who is running the anonymous block? If there are other schemas involved, what are they? What are they doing? What privileges do they have on the type or the function?
Post a complete test script that people can run to re-create the problem and test their ideas.

Problem passing oracle.sql.ARRAY to Oracle

I am having ClassCastException when I try to pass a oracle.sql.ARRAY to a Oracle Package.
Here is my code:
PreparedStatement stmt = null;
String strArray[] = { "1,2,3,4,5" };
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
//encounter Exception on the line below.
ARRAY array_to_pass = new ARRAY( descriptor, dbConnection, strArray );
String queryStr = "begin TEST_PAC_1.TEST_PROC_2(?); end;";
stmt = dbConnection.prepareStatement(queryStr);
stmt.setArray( 1, array_to_pass );
stmt.execute();
I understand that oracle.sql.ARRAY has been replaced by weblogic.jdbc.vendor.oracle.OracleArray in Weblogic.
MY QUESTION IS: HOW DO I INSERT MY STRING ARRAY INTO THE OracleArray and pass it to the plsql.
Really frustrated searching through the forums for the whole day,
Thanks,

Try this if you are at weblogic 8.1:
Connection con = getConnectionFromDataSource();
Connection vendorConnection = ((WLConnection)con).getVendorConnection();
// use direct oracle connection.
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
vendorConnection.close();
Beware that you should be very careful as you are going to use a direct vendor
connection.
The better aproach is to pass the string array as a delimited string to your storad
procedure and parse it in the SP - then you don't have to mess up with vendor-specific
handling.
Hope this helps.

I would appreciate any help in resolving this issue.
Thanks,

Not possible. For valid technical reasons.
Definitions are local to a database. You can define a SQL user type called TMyType in your database. I can define one in mine with the same name.
Can you now call my database, passing a collection of your TMyType to me? How do we (or Oracle) know that your definition and my definition is the same? Or if they were the same when you compiled your code (and your Oracle checked my Oracle to confirm), that they still are the same and that I did not in the meantime altered the type? Or even dropped it?
For types/collections to be transparently passed across to database links, we need something along the lines of:
a) global types
b) runtime checking of types
Both are problematic to implement and maintain. With (a) there is the issue of dependencies. The global type cannot be changed before all dependencies on all subscribers have been resolved. With (b) there is the issue of performance, checking the type definitions with every single call on the local & remote instances to compare.
It would be a nice feature to have... but it would fail to live up to expectation if not implemented in a robust and performant way.
Alternative. "Insert" data via a remote proc into a remote collection. This allows you to push data into a PGA memory structure on the remote side and when done, allows you to tell that remote proc to "flush" (forall insert/update/delete) the contents of that structure to disk.

Passing collection or array to function: shallow copy or not?

Hello all,
When passing a collection or an array to a function, what is most used practice to store the given collection in some class member field: reference-copy or a shallow copy?
I believe it's frustrating to see that there is no real 'standard' about this: some developers copy the whole collection/array, others prefer to simply copy the reference. I tend to agree with the latter group:
- it's the user's responsibility if he wants the class to use a copied version instead of the 'original' version of the collection/array.
- most of the times, a copy is not needed, and therefor a shallow copy is pure waste of resources.
- when nothing is known about the given collection, and there are also no restrictions on the collection to be given, it could be everything: ArrayList? HashSet? SortedSet? AnUnknownImplementation?
reference copy:
class ComeClass
    private ArrayList list;
    public SomeClass(ArrayList list) { this.list = list; }
}shallow copy:
class ComeClass
    private List list;
    public SomeClass(List list) { this.list = new ArrayList(list); }
}What are your thoughts about this?

basically, it's how much access you want to provides.
public SomeClass(ArrayList list) { this.list = list; }to me, if some other class has a reference to the list object and start modifying it..Someclass internal data (the list) is also modified...thus breaking encapsulation.
yes, in multithread enviroment, sharing the list(by reference can lead to some hard bug to debug), so it;s much safer to copy (clone) the list. Java does this and provides you the MultiCaster class to make thing easier for you.
even with synchronization, there are issues you have to look at (such as deadlock)..you can synchronize the list, but can still run into a dead lock
list is synchronized in class A
class B have object (that's in list and call the list (wait due to class A synchronization)
list tries to invoke method of class B, but wait (class B is lock)..thus..deadlock.
it's a crued exapmle..but i think you get the point.
the saying is that to make a safer application..declare all you object immutable or restrict access to your private data. Of course, performance wise, we have to comprise sometime.
example..a list with over 500,000 objects..you might not want to to clone the reference.

Pass SQL into a Function

Is it possible to pass a SQL into a Function
DECLARE
   f        sys_refcursor;
   RESULT   NUMBER;
   FUNCTION myfunction (r sys_refcursor)
      RETURN NUMBER
   IS
   BEGIN

   END;
BEGIN
   OPEN f FOR
      SELECT SYSDATE dt
        FROM DUAL;
   RESULT := myfunction (f);
   CLOSE f;
END;

Yes you are allowed to pass ref cursor but they have to processed the way you processur cursor i.e. OPEN, FETCH, CLOSE.
See demonostration of working code:
SQL>DECLARE
2     f        sys_refcursor;

Passing a Variant array to ArrayToImage Function

Hi,
I need help passing a Variant array to the ArrayToImage function in the NI Vision library.
I have no problems using the ImageToArray function - but when going back to the CWIMAQImage type the application throws an exception.
Are there any code samples for doing this?
Thanks!

Hello,
Thank you for posting to the NI forums! Try calling the ImageToArray function then immediately passing the resultant array back to ArrayToImage. That will determine whether the ArrayToImage function is causing the error, or the array that is passed into it. Can you post a small sample of how you call the ArrayToImage function and the errors that are thrown?
Thanks,

Passing 3d arrays to functions in C

So.. I have a certain char array[8][3][30], declared as ***array, and allocated as the program progresses. I'd like to pass that to an external function, but GCC pukes out warnings that the type case isn't right, and anytime I access it in the function, it segfaults (basically, it doesn't pass properly).
my function prototype:
int parse_table(char ***table);
and code to pass it:
parse_table(table);
anyone knowledgable on this?

tardo wrote:main()
char ***table;
parse_table(table);
use_table(table);
parse_table(char ***table)
// read one value from file
// determine other two values from file input
// allocate memory depending on values (varies with file input)
use_table(char ***table)
// programming homework (probably a tree)
AHEM, so, I actually bothered to read this properly this time . If this is actually how you have your code structured, this is definitely a problem. Think about this: "table" is of type "char ***", correct? parse_table takes a type "char ***"... you have pass-by-value semantics here. So, essentially, parse_table will receive a COPY of an unitialized memory location. You will then set this local copy to the return of malloc (e.g. something lik table = malloc(/*stuff*/)). However, this is not affecting the table seen in main()! Essentially, you should have something like:
int main() {
char ***table = parse_table();
/* rest of main */
char *** parse_table() {
/* Stuff that mallocs into local_table pointer */
return local_table;
Where, you malloc the stuff in parse_table, and return that pointer. Alternatively (and painfully), you could do something weird like:
int main() {
char ***table;
parse_table(&table);
/* rest of main */
void parse_table(char ****table) { /* Note: four "asterisks", not three! */
/* malloc evilness in here, with something like (*table) = malloc(/* stuff */) */
(Don't do this, it's ugly and unnecessary)
Just to be completely pendantic, check it this sample code I whipped up:
#include <stdlib>
#include <stdio>
void evil_and_wrong(char *f) {
printf("Memory location we'd allocate to (evil_and_wrong): %un", &f);
f = (char*)malloc(5*sizeof(char));
f[0]='p';
void my_alloc_f(char **f) {
printf("Memory location we'd allocate to (my_alloc_f): %un", f);
(*f) = (char*)malloc(5*sizeof(char));
(*f)[0]='p';
char * nicer_my_alloc_f() {
char *local_f = (char*) malloc(5*sizeof(char));
local_f[0]='p';
return local_f;
int main() {
char *f;
printf("ACTUAL Memory location: %un", &f);
evil_and_wrong(f);
// We won't try anything with "f" here, since it'll segault...
my_alloc_f(&f);
printf("Should see: %un", 'p');
printf("See: %un", f[0]);
free(f);
f = nicer_my_alloc_f();
printf("See: %un", f[0]);
free(f);
return 0;
Look at the outputted memory locations, and think about the fact you're trying to store the address of the allocated memory...

PL/SQL array passed to SQL IN

Hi,
I have a PL/SQL array which type is defined like this:
create or replace type type_id_array as table of number(6, 3);
then i create a variable and initilaize:
var_1 type_id_array;
var_1 := .....
then i have a select statement.
select * from table t where t.id in(var_1)
That's it, i want to use the array in an SQL in. This seems not possible.
Can you explain why? Any alternate solutions?
Thanks

ABAP/4 Open SQL array insert results in duplicate database records in SM58

Hi Everyone,
I am testing a file to idoc scenario in my Quality system. When I passed the input file, the mapping executed successfully and there are no entries in SMQ2 but still the idoc wasn't created in the ECC system. When I have checked in TRFC, I am getting the error ABAP/4 Open SQL array insert results in duplicate database records for IDOC_INBOUND_AYNCHRONOUS function module. I thought this is a data issue and I have tested with a fresh data which was never used for testing in Quality but even then I am getting the same error.Kindly advise.
Thanks,
Laawanya

use FM idoc_status_write_to_database to change the IDoc status from 03 to 30 and then run WE14 or RSEOUT00 to change the status back to 03
resending idoc from status 03 ...is a data duplicatino issue on receiving side...why do u need to do that ?
Use WE19 tcode to debug
In we19
1)U can choose your Idoc number in existing Idoc textbox
2)Press execute
3)u will display ur Idoc struct
4)Dbl click on any field then u can modify its content
5)PressStd Outbound Processing Btn to process modified Idoc
Thats it

How to find out the execution time of a sql inside a function

Hi All,
I am writing one function. There is only one IN parameter. In that parameter, i will pass one SQL select statement. And I want the function to return the exact execution time of that SQL statement.
CREATE OR REPLACE FUNCTION function_name (p_sql IN VARCHAR2)
RETURN NUMBER
IS
exec_time NUMBER;
BEGIN
--Calculate the execution time for the incoming sql statement.
RETURN exec_time;
END function_name;
/

Please note that wrapping query in a "SELECT COUNT(*) FROM (<query>)" doesn't necessarily reflect the execution time of the stand-alone query because the optimizer is smart and might choose a completely different execution plan for that query.
A simple test case shows the potential difference of work performed by the database:

Call a PL/SQL procedure or function from applet

Could anyone please let me know how I could call a PL/SQL procedure
or function from a JDBC method from applet with Internet Explorer?

It depends from where you are calling your PLSQL routine. If it is SQL*Plus then you can use & (ampersand) with the variable to be input at run time.
If you are executing the PLSQL routine from another application (some front end application) then it's not possible. Because when a procedure is executing at server side, the front end application does not have control, and the control is only transfered back to front end application when the PLSQL routine either completes successfully or throws an exception.
In either case, you can not go back to the PLSQL routine.
In this case, what you can do is, write code in your front end application to get that variable value from user and then pass that value to PLSQL routine.

Can't we pass java.sql.Connection as parameter toDatum() method

I am in mid of java 1.3 to 1.4 migration, now I am getting the below error.can't we pass java.sql.Connection as a param to toDatum(), but I did the same before for another module and it worked fine, now I am getting the error.
any changes need to be done?
[b]toDatum(oracle.jdbc.driver.OracleConnection,java.lang.String) in oracle.jpub.runtime.MutableArray cannot be applied to (java.sql.Connection,java.lang.String)

1 error
I changed to use

import oracle.sql.ORADataFactory;
instead of

import oracle.sql.CustomDatumFactory;

In general, it's bad practice to be that "open" with regards to parameters to methods, especially when using remote invocations. However, if you really, really, really, really need to - and I doubt you do - you can use Serializable for the type of parameter. But that's still inelegant and, well, raises all sorts of issues, starting with your design...

How to create oracle.sql.array

I need to create an oracle.sql.array to pass in my custom objects array to the database. I know you can create it using the ArrayDescriptor class but the problem with that is the connection object is need.
I am using the writeSql() method of the SQLData interface. I therefore dont have the connection object. Any ideas?

haha
you misunderstand. i have in my code:
<code>
     // update the organisation
     public boolean setOrganisation(Organisation pOrg) {
          Organisation org = pOrg;
          OracleCallableStatement callStat = null;
          Connection conn = null;
          boolean OK = false;
          try {
               conn = getConnection(getUserName());
               pOrg.setConnection(conn);
               callStat = (OracleCallableStatement) conn.prepareCall("{call p_cmt.update_organisation(?)}");
               callStat.setObject(1, org);
               callStat.execute();
               OK = true;
          } catch (Exception e) {
               logger.severe("error writing organisation with id " + org.getId() + ". " + e);
          } finally {
               cleanUpConnections(conn, callStat);
          return OK;
</code>
This writes the object organisation to the database. Now in the class organisation i have the following method which is called automatically when writing the organisation object to the database:
<code>
     public void writeSQL(SQLOutput p_stream) throws SQLException {
          p_stream.writeInt(id);
          p_stream.writeObject(country);
     if (finIndexArr == null)
          finIndexArr = new ListElement[0];
     ArrayDescriptor af = ArrayDescriptor.createDescriptor(
     ObjectMapper.elementList, conn);
     ARRAY arr = new ARRAY(af, conn, finIndexArr);
          p_stream.writeArray(arr);
</code>
The problem is the last bit. To put the finIndexArr into an array i need the connection object. So i have to pass into the organisation object the connection object which seems unneccessary and pointless to me. I was just looking at an alternative way of creating the array without the need of the connection object. Since the setOrganisation() above has the connection to the database i dont see why i need to specify it in the array as well

Bind PL/SQL array to PHP array

Hi all!
I try to bind a PL/SQL array (nested tables, index by integer) returned by a PL/SQL-function to an PHP array.
Here is the code:
create or replace package MyPackage as
TYPE my_type IS TABLE OF VARCHAR2(1024);
FUNCTION MyFunction RETURN my_type;
end MyPackage;
create or replace PACKAGE BODY MyPackage is
FUNCTION MyFunction RETURN my_type IS
t_docs my_type;
begin
t_docs := my_type('val0','val1','val2');
return t_docs;
end MyFunction;
end MyPackage;
In the PHP-code ist looks like this
$query = "begin :vals := MyPackage.MyFunction; end;";
$stmt = oci_parse ($conn, $query);
oci_bind_array_by_name($stmt, ":vals", $vals_array, 5, 512, SQLT_CHR);
oci_execute ($stmt);
Output:
PLS-00382: expression is of wrong type. Error in Line....
This error point to
begin :vals := MyPackage.MyFunction; end;
^^^
Questions:
Is it generally possible to bind a pl/sql array to a php array? Or only the other was around?
Could you please post a snipet of code how to do it the right way :-)
Thanks a lot for your help! Christian

As you noted, you can't return a PL/SQL array and map it to a PHP array when it is a record type. Likewise, you can't map an object type to a PHP array. You can return a reference cursor through PL/SQL, and then fetch the function result with oci_fetch_assoc($rc).
Alternatively, you can return an object type collection or a pipelined table function result into PHP. It's a bit long but you'll find examples on my blog. Start here, and there's a link to a full discussion of pipelined table functions:

This is an object table example, which you may prefer over pipelined table functions:

Hope this helps.

SQL User Defined Functions for performing statistical calculations

Hi!
   I hope you can help. I just wasn’t sure where to go with this question, so I’m hoping you can at least point me in the right direction.
   I’m writing a SQL Server stored procedure that returns information for a facility-wide scorecard-type report. The row and columns are going to be displayed in a SQL Server Reporting Services report.
   Each row of information contains “Current Month” and “Previous Month” numbers and a variance column. Some rows may compare percentages, others whole numbers, others ratios, depending on the metric they’re measuring. For each row/metric the company has specified whether they want to see a t-test or a chi-squared statistical test to determine whether or not there was a statistically significant difference between the current month and the previous month.
   My question is this: Do you know where I can find a set of already-written user defined functions to perform statistical calculations beyond the basic ones provided in SQL Server 2005? I’m not using Analysis Services, so what I’m looking for are real SQL User Defined Functions where I can just pass my data to the function and have it return the result within a stored procedure.
   I’m aware that there may be some third-party statistical packages out there we could purchase, but that’s not what I’m looking for. And I’m not able to do anything like call Excel’s analysis pack functions from within my stored procedure. I’ve asked. They won’t let me do that.   I just need to perform the calculation within the stored procedure and return the result.
   Any suggestions? Is there a site where people are posting their SQL Server UDF’s to perform statistical functions? Or are you perhaps aware of something like a free add-in for SQL that will add statistical functions to those available in SQL? I just don’t want to have to write my own t-test function or my own chi-squared function if someone has already done it.
Thanks for your help in advance! Oh, and please let me know if this should have been posted in the TSQL forum instead.  I wasn't entirely sure.
