Pass List of

Good Morning,
I need to break up a list of about 45,000 IDs to pass about 5,000 at a time into a query on DB2 via an Expression on a Data Flow Task. The query works when hard coding the values into the query (see A below). I can also pass a single value (05404928)
into the variable and it works as in B. I cannot seem to get a statement where multiple values are passed into the variable as a string (like 05404928,01264567) to work as in C, however. I am not sure if it's the syntax/combination of single/double
quotes or whether this approach is just not possible. Is this possible or am I approaching this problem from completely the wrong way? Thanks kindly for any thoughts.

You can use a >= AND <= condition for that
You can set it up as follows
1. Add an execute sql task with oledb connection manager connecting to sqlserver database and use a query like
SELECT DISTINCT ((ROW_NUMBER() OVER (ORDER BY ID)-1)/5000) + 1 AS Grp,MIN(ID) AS MinID,MAX(ID) AS MaxID
FROM
( VALUES (05404928),(01264567),...)
)t(ID)
replace .. with all your ID values.Choose resultset option as Full resultset and map the resultset to object variable created in SSIS (say @[User::IDList]) by mapping to index 0 in mapping tab
2. Add a ForEach loop with ADO enumerator based on IDList variable. Add two variables inside of type int to get iterative MinID and MaxID values by mapping to indexes 1 and 2
3. Inside loop add your data flow task with Db2 query
4. Add a lookup task and add the sqlserver connection manager as connection. use custom query option and use query as
SELECT ID
FROM
( VALUES (05404928),(01264567),...)
)t(ID)
WHERE ID >= ?
AND ID <= ?
and map the parameters to MinID and MaxID variables
Choose the lookup failure option as Redirect to NoMatch output
5. Take match output from lookup task and link it to further tasks

Pass List MyObject as a parameter with jax ws web service

Hi,
I need to pass a list of strongly typed object as a parameter in my web service which utilizes jax ws.
For some reason I am not able to pass more than one.
For example if do the following in my soap message:
<Objects>
   <Object>
        <property>myVal</property>
   </Object>
<Object>
        <property>myVal</property>
   </Object>
</Objects>The above will be treated as one object in my java code.
Edited by: kminev on Dec 15, 2009 11:55 AM

WIS is not suppported on WLS JAX-WS. You'll need to use other authentication mechanisms such as http basic (which you tried already), or message-level security such as UNT, or SAML.

SQL Query: How to pass list of values to the IN operator

Hi,
I'm trying to pass a list of values to the WHERE <a> IN <list>
I dont want to use dynamic cursors (REF CURSOR). Is this possible using Oracle SQL?
Please let me know.
My program:
DECLARE
list_of_ids := '10, 20, 30';
SELECT MAX(sal) INTO max_sal FROM employee WHERE emp_id IN (list_of_ids);
END;
Thanks in Advance,
Niko

You do not want to pass a comma separated list. You want to pass a collection. So
CREATE TYPE num_tbl
AS
TABLE OF NUMBER;
DECLARE
l_list_of_ids num_tbl := num_tbl( 10, 20, 30 );
BEGIN
SELECT max(sal)
    INTO max_sal
    FROM employee
   WHERE emp_id IN (SELECT * FROM TABLE( l_list_of_ids ));
END;

Passing list of values to a function

As what type list of values multiple selections, e.g. resulting in (1,2,3), are represented in function parameters?
for example i have lov that results in (1,2,3) and dataset query is select myfunction(:mylov) from dual.
Variable of what type I must declare in function definition?

when i hadthe same situation , i used cursor query to resolve .
eg.
select myfunction(cursor(select field1 from table1 where field1=:parameter1)) from dual
In the PL sql function get all thee parameters from the cursor variable and pass into the looping statement for furthur processing

Passing list collection from page to page

Using wp 8.1 and c#, I need to build a collection on one page1, then use the collection throughout the app for every page including page2, page3, page4, etc.
Can anybody offer advise to consider?
I thank the Lord Jesus for your kind effort and patience with me (Jeremiah 9:23-24 of the Holy Bible).

Is this Silverlight or is it windows store app?
It doesn't matter a great deal.
You have three options.
1)
You can add any old object you like to resources and there's an application scoped set of resource.
In windows store apps I think that'd be app.current.resources and in silverlight it's application.current.resources.
You do:
Application.Current.Resources.Add("somekey", yourlist);
and that adds it to your resources.
App.current... for win store app.
To get a reference back to that thing ( note, it's a reference and therefore the same object).
List<t> mylist =Application.Current.Resources["somekey"] as List<t>;
Obviously, that list can instead be some other sort of collection and <t> is the type of the objects in it.
You can see this approach used in one of my WPF samples:
https://gallery.technet.microsoft.com/Dynamic-XAML-Composed-View-e087f3c1
This shares two observable collections in a similar manner.
It proves they are definitely the same object because you can edit a person and see the changes immediately in the corresponding datagrid row.
2)
You could alternatively send the List<t> using Mvvm Light messenger in an object and subscribe to that object type in the "receiving" pages. They would have to be in memory and I think option 1 is your best bet.
3)
You could create the collection in one place - like mainpage eg. Then pass that collection via the constructors of the other pages as you new them up. I don't really like this approach because it introduces a dependency to all those pages which
means testing etc is harder. I don't consider it a professional approach if there's an alternative - but it's an approach plenty of professionals advocate so your mileage may vary.
It's not really any simpler than using resources.
Hope that helps.

Pass list of values in an array to the IN statement of SELECT in Oracle 10g

Hi,
This is what I have done so far...
I have loaded the main array array_number_1 using BULK Collect. Within the loop I am filtering the data from this array and writing to another array array_number_2.
I want to use the values from array_number_2 in the SELECT statement.
Eg: SELECT sum(x_amount) charges
FROM x_table
WHERE id IN (array_number_2).
Could you provide a solution to this preferrably with an example.
thanks

I'm not entirely following you, Visakh, but I have a SQL Task setup in which I have an expression that makes a call to a db2 database such as the abbreviated set example below. The list of IDs in the IN statement must come from another SQL Server
database. In the past I have gotten the list of IDs, put them in a recordset and then put that in a for loop to iterate and make one call to db2 for each and every ID. The single ID example can literally take days to run for 100,000 IDs.
Therefore, I want to pull the entire set of results back at one time via a single (or at least fewer calls than there are IDs) DB2 call using 'in' instead. Maybe I am overlooking something but I don't quite see how your example will get me where
I want to go.
Set Example
SELECT
A,
B
FROM
Table 1,
Table 2,
WHERE
    Joins
AND PRSNEUP.ID in ( This is where I want a list of IDs )
Single ID Example
SELECT    A,
B
FROM
Table 1,    Table 2,
WHERE
Joins      AND PRSNEUP.ID = ( VariableContainingASingleID

How to pass list of values to REF CURSOR?

Hi there,
I have a package for ref cursor return as following:
<pre>
create or replace package p_mypkg as
type t_ref_cur is REF CURSOR;
function f_t_refcur (strsql varchar2) return t_ref_cur;
end;
create or replace package body p_mypkg as
function f_t_refcur(strsql varchar2) return t_ref_cur as
     cur t_ref_cur;
sql_stmt varchar2(1000);
     begin
sql_stmt:='select object_name,object_type from user_objects where object_type in (:j)';
          open cur for sql_stmt using strsql;
          return cur;
     end;
end;
var results refcursor
begin
:results:=p_mypkg.f_t_refcur('TABLE');
end;
print results
var results refcursor
begin
:results:=p_mypkg.f_t_refcur('INDEX');
end;
print results
I got the result sets using just one value.
But I got nothing when use two values as input.
Any idea?
var results refcursor
begin
:results:=p_mypkg.f_t_refcur('''TABLE'',''INDEX''');
end;
print results
SQL>
no rows selected
Thanks,
SZ

You can also use ...from table(... :
create or replace type numbertype
as object
(nr number(20,10) )
create or replace type number_table
as table of numbertype
create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
open p_ref_result for
    select *
    from employees , (select /*+ cardinality(tab 10) */ tab.nr from table(p_numbers) tab) tbnrs
    where id = tbnrs.nr;
end;

Passing dynamic list / array of values to Droplet

Any examples here?

u can refer to the following droplet , it uses both list and array

<param name="items" value="param:product.childSKUs">

<oparam name="output">

<droplet bean="/atg/dynamo/droplet/ForEach">

<param name="elementName" value="pricedItem">
<oparam name="output">
<valueof param="pricedItem.auxiliaryData.catalogRef.displayName"></valueof> -

<droplet bean="Switch">
<param name="value" value="param:pricedItem.priceInfo.onSale">
<oparam name="false">
<valueof param="pricedItem.priceInfo.amount" currency>no price</valueof>
</oparam>
<oparam name="true">
List price for <valueof param="pricedItem.priceInfo.listPrice" currency>no price</valueof>

Passing a list as a parameter to a function

Hi,
I am relatively new to PL/SQL, but am used to passing lists to functions in other languages. In my PL/SQL function, currently I assign a SELECT to a cursor, and in the WHERE clause for the select, I have something hardcoded like
WHERE field_name = ('apple', 'bat', 'cat').
I would like to replace it by something like
WHERE field_name = list_name
where list_name is passed as a parameter to the function that I am defining. The reason I want to do this is because my list_name can have many more than three things in the future.
Does PL/SQL support an easy way to do this? I have asked around with no success, but it seems to me that a language like PL/SQL ought to have something to support it, since just about every modern language does.
Thanks,
Regards,
Srini

The trickiest part of the asktom solution is ensuring the cardinality hint is used to help the optimizer understand that the in-list you are building likely contains only a handful of values instead of it 1 whole block worth assumption.
The default assumption without the cardnility hint will ensure that an index on the column that is used for the IN clause will never be used, resulting in horrible performance.
I think 10g fixes this, and does some dynamic sampling of the collections returned through that approach. I am not quite 100% sure about that, but I think that is the case.
