Different ways to return results using a stored proc to calling application

Hi, Can someone please suggest me different ways of returning results( set of rows and columns) from a stored procedure to calling application.
Currently I am using sys_refcursor to return results to front end. Stored proc is executed fast, but cursor access and retrieval of results has some overhead.
So can you suggest the ways which will be faster than this approach.
Thanks.

Currently the procedure executes quickly but the results from the ref cursor are returned slowly, this is because the query is slow, for whatever reason.
Collecting in all the rows in the stored procedure first before returning them will
a) Make the stored procedure slower taking the same amount of time to execute as current query takes to complete.
b) Use more memory.
c) Put more stress on the network as all rows will be transferred at once instead of using the arraysize/fetchsize to to fetch the rows in smaller packets.

Parallel Processing : Unable to capture return results using RECIEVE

Hi,
I am using parallel processing in one of my program and it is working fine but I am not able to collect return results using RECIEVE statement.
I am using
CALL FUNCTION <FUNCTION MODULE NAME>
STARTING NEW TASK TASKNAME DESTINATION IN GROUP DEFAULT_GROUP
PERFORMING RETURN_INFO ON END OF TASK
and then in subroutine RETURN_INFO I am using RECEIVE statement.
My RFC is calling another BAPI and doing explicit commit as well.
Any pointer will be of great help.
Regards,

I used the wait command after rfc call and it worked additionally I have used Message switch in Receive statement because RECIEVE statement was returing sy-subrc 2.

Not sure what's going on here. Possibly a corrupt drive? Or the target drive is full?

Trying to Execute Catalog SSIS Package using Catalog stored proc by a Master SSIS package inside a Loop

Hi Guys ,
To Execute Packages deployed in Catalog , I have created a wrapper SP which internally calls catalog SP ( below is the code )
ALTER PROCEDURE [Publish].[usp_ExecutePackages]
@PackageName NVARCHAR(255)
, @ProjectFolder NVARCHAR(255)
, @ProjectName NVARCHAR(255)
AS
BEGIN
SET NOCOUNT ON;
DECLARE @Execution_id BIGINT ;
EXEC [SSISDB].[catalog].[create_execution] @package_name
= @PackageName
, @execution_id
= @Execution_id OUTPUT
, @folder_name
= @ProjectFolder
, @project_name
= @ProjectName
, @use32bitruntime=
True;
EXEC [SSISDB].[catalog].[set_execution_parameter_value]
@execution_id,
@object_type=50,
@parameter_name=N'SYNCHRONIZED',
@parameter_value=1
EXEC [SSISDB].[catalog].[start_execution] @Execution_id
Since i have multiple Packages , I am looping through list of PackageName and trying to pass package names to this SP by ExecureSQLTask inside ForLoop Container . But it errors out saying
"Cannot access the package or the package does not exist. Verify that the package exists and that the user has permissions to it.
BUt same Execute SQL task , if i keep it outside the ForLoop Container it works perfectly fine .
I am clueless , Please Please HELP me ASAP :(
Question :
How is that possible to execute same SP with same parameter outside Container , But not in SEQUENCE or FORLOOP or FOREACH Container ?
Also
How to make a master package to execute SSIS deployed packages via TSQL using catalog stored proc ?
Please help me out .
Thanks

Hi ,
After debugging i am getting parameter values as
{Extract - ARTL.dtsx\r\n} Unable to evaluate the expression.
Why do i get \r\n which i dont want in parameters .
Actually i pick the values of package name from a custom table . I check it there are no spaces in the cell.
Any IDEA WHY ? Please help
Finally it worked to call Wrapper Class for EXEC [SSISDB].[catalog].[create_execution]
stored procedure .
Basically , ERROR MESSAGE is culprit
"Cannot access the package or the package does
not exist. Verify that the package exists and that the user has permissions to it.
Above Message : causing us to think
its an Access issue , But actually when you pass parameter incorrectly even a " " space or "\n" extra to value, you will get that error .
Nothing related to access problem .
Actually , In the parameter which i was passing :
{Extract - ARTL.dtsx\r\n} --> String with Enter / Carriage Return and Break line was there
I have removed the Enter in that variable value .
Now its WORKING FINE ! Hurry :D :)

I don't understand what you are asking - what are you trying to do ?

Tuning a procedure and using dbms_job.submit proc that call's functions

Hi
I have Procedure that have 3 curosrs which are nested one below with in each other
and it looks as below
it's structure will look some thing look like this
declare
empno_fetch number;
CURSOR deu_process IS
SELECT empno
FROM emp
WHERE flg_process = 'N'
AND ROWNUM <= 5000
ORDER BY empno;
CURSOR dup_all IS --c1 fetch around 400000 records
(select empno
from emp
where empno>l_empno
order by empno
where rownum<=empno_fetch;
CURSOR rules IS --c2
SELECT rule_id, rule_score, name_Of_func
FROM rule;
begin
l_count := 1;
OPEN dedupe_rule_attr;
LOOP
BEGIN
Here one loop is used for fetching 5000 records at time and
Here deu_process cursor is opened ,assume it fetches one record
Here another cursor dup_all is used for fetching the records and assume it fetched 400000 then
Here another cursor is opened name where it fetches 10 rows
Here logic is if first row then
call's stored function which has following functionalty
it compares fields such as address of outer most cursor i.e deu_process with all the address of the other rows i.e 400000 rows and return a number
if second row then
call's another stored function which has
compares other fields such as first name,last name
if third then other field
so on ....
up to 10
and then finally ends
so if i comment all the rules loop then it takes only one min to execute .If it validaes all of them if takes 14 minutes to execute .so there is problem in that 10 procedures to execute
So i found an approach to run all the rules simultaneously using dbms_job .But i face a problem that i can't uderstand how to send the input and out put parameter's to calling procedure.And these parameter's must be passed by variable from called procedure to calling procedure
Please suggest me what is the syntax of dbms_job with input and output parameters with variable's that must be passed as formal parameter's
Regarding DBMS_JOB.SUBMIT I am getting following error
Declare
x number:=1;
b number;
jobnumber number;
BEGIN
DBMS_JOB.SUBMIT(JOB => jobnumber,
WHAT => 'vamsi_proc1('||x||');',
NEXT_DATE => (sysdate+1/(86400)),
INTERVAL => null);
--dbms_output.put_line('value of b is '||b);
COMMIT;
END;
Declare

begin
--a:=1;
insert into emp_vamsi(select 677,ENAME,SAL,DEPTNO,MANAGER from emp where empno=v);
commit;
--a:=2;
--x:=a;
end;
using dbms_job.submit proc that call's functions which returns out and in parameters to calling procedure environment .I can't get this with out using data base table's.
If you have any method for this Plese suggest
And also please suggest me weather using job's is a good idea ,If not than suggest me what ever will the other approach.
Thank's and Regard's

Hi 
I have looked at all sql trace file , 
I found that there is no problem in sql statemens all of them are using proper indexes execpt the folllowing statement 
 
SELECT nvl(COUNT(ref_appln_no),0) 
FROM ci_cust_dedupe_mast 
WHERE flg_mnt_status='A' 
 
This statement executes only once for 1*3,77000*10 times 
The function that i had sent previously executes more than 4000000*20 times . 
I think all it takes is only for iterations that are caused 
 
I am also sending sql trace for reference

The ways to return data from a stored procedure.

Hi, I know there are three ways to pass out a value from a Microsoft SQL stored procedure, but I have no clear idea what Oracle SP can do, I know Oracle doesn't support multi-recordset(v8), can not return a recordset by a inner select query, but I do know there is a cursor object, which doesn't like its counterpart in Microsoft SQL server, is a choice under most situation. Here I wonder anyone who is good at Oracle can give a list of all ways to return data from a SP, including example is more better, thanks.

Here is a way to get return a record from a function and a procedure. You need to be familiar with Oracle packages as well as stored procedures and functions:
CREATE OR REPLACE PACKAGE EmpPkg AS
cursor cEmp(pEmpno in number) is
select empno, ename, job, hiredate, sal
from emp
where empno = pEmpno;
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype);
END;
CREATE OR REPLACE PACKAGE BODY EmpPkg AS
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype IS
rEmp cEmp%rowtype;
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into rEmp;
close cEmp;
return rEmp;
END;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype) IS
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into prEmp;
close cEmp;
END;
END;
Here's how you use the package:
DECLARE
rEmp EmpPkg.cEmp%rowtype;
BEGIN
rEmp := EmpPkg.GetEmployee(7782);
dbms_output.put_line(rEmp.ename);
EmpPkg.GetEmployee(7902, rEmp);
dbms_output.put_line(rEmp.ename);
END;
Note that you can return any Oracle data type from a function. Likewise, you can specify any Oracle data type as an out parameter in a procedure. Also, you can make a parameter both an in and an out datatype like this:
PROCEDURE GetEmployee(pnEmpNo in out number);
I hope this puts you in the right direction.

Problem Obtaining multiple results from MySql Stored Proc via JDBC

I've spent alot of time on this and I'd be really grateful for anyones help please!
I have written a java class to execute a MySQL stored procedure that does an UPDATE and then a SELECT. I want to handle the resultset from the SELECT AND get a count of the number of rows updated by the UPDATE. Even though several rows get updated by the stored proc, getUpdateCount() returns zero.
It's like following the UPDATE with a SELECT causes the updatecount info to be lost. I tried it in reverse: SELECT first and UPDATE last and it works properly. I can get the resultset and the updatecount.
My Stored Procedure:
delimiter $$ CREATE PROCEDURE multiRS( IN drugId int, IN drugPrice decimal(8,2) ) BEGIN UPDATE drugs SET DRUG_PRICE = drugPrice WHERE DRUG_ID > drugId; SELECT DRUG_ID, DRUG_NAME, DRUG_PRICE FROM Drugs where DRUG_ID > 7 ORDER BY DRUG_ID ASC; END $$
In my program (below) callablestatement.execute() returns TRUE even though the first thing I do in my stored proc is an UPDATE not a SELECT. Is this at odds with the JDBC 2 API? Shouldn't it return false since the first "result" returned is NOT a resultset but an updatecount? Does JDBC return any resultsets first by default, even if INSERTS, UPDATES happened in the stored proc before the SELECTs??
Excerpt of my Java Class:
// Create CallableStatement CallableStatement cs = con.prepareCall("CALL multiRS(?,?)"); // Register input parameters ........ // Execute the Stored Proc boolean getResultSetNow = cs.execute(); int updateCount = -1; System.out.println("getResultSetNow: " +getResultSetNow); while (true) { if (getResultSetNow) { ResultSet rs = cs.getResultSet(); while (rs.next()) { // fully process result set before calling getMoreResults() again! System.out.println(rs.getInt("DRUG_ID") +", "+rs.getString("DRUG_NAME") +", "+rs.getBigDecimal("DRUG_PRICE")); } rs.close(); } else { updateCount = cs.getUpdateCount(); if (updateCount != -1) { // it's a valid update count System.out.println("Reporting an update count of " +updateCount); } } if ((!getResultSetNow) && (updateCount == -1)) break; // done with loop, finished all the returns getResultSetNow = cs.getMoreResults(); }
The output of running the program at command line:
getResultSetNow: true 28, Apple, 127.00 35, Orange, 127.00 36, Bananna, 127.00 37, Berry, 127.00 Reporting an update count of 0
During my testing I have noticed:
1. According to the Java documentation execute() returns true if the first result is a ResultSet object; false if the first result is an update count or there is no result. In my java class callablestatement.execute() will return TRUE if in the stored proc the UPDATE is done first and then the SELECT last or vica versa.
2. My java class (above) is coded to loop through all results returned from the stored proc in succession. Running this class shows that any resultsets are returned first and then update counts last regardless of the order in which they appear in the stored proc. Maybe there is nothing unusual here, it may be that Java is designed to return any Resultsets first by default even if they didn't happen first in the stored procedure?
3. In my stored procedure, if the UPDATE happens last then callablestatement.getUpdateCount() will return the correct number of updated rows.
4. If the UPDATE is followed by a SELECT (see above) then callablestatement.getUpdateCount() will return ZERO even though rows were updated.
5. I tested it with the stored proc doing SELECT - UPDATE - SELECT and again getUpdateCount() returns ZERO.
6. I tested it with the stored proc doing SELECT - UPDATE - SELECT - UPDATE and this time getUpdateCount() returns the number rows updated by the last UPDATE and not the first.
My Setup:
Mac OS X 10.3.9
Java 1.4.2
mysql database 5.0.19
mysql-connector 5.1.10 (connector/J)
Maybe I have exposed a bug in JDBC?
Thanks for your help.

Jschell thank you for your response.
I certainly don't mean to be rude but I often get taken that way. I like to state facts as I see them. I'd love to be proved wrong because then I would understand why my code doesn't work!
Doesn't matter to me if you are rude or not. Rudeness actually makes it more entertaining for me so that is a plus. Nothing I have seen suggests rudeness.
In response to your post:
When a MySql stored procedure has multiple sql statements such as SELECT and UPDATE these statements each produce what the Java API documentation refers to as 'results'. A Java class can cycle through these 'results' using callableStatement dot getMoreResults(), getResultSet() and getUpdateCount() to retrieve the resultset object produced by Select queries and updateCount produced by Inserts, Deletes and Updates.
As I read your question it seems to me that you have already proven that it does not in fact do that?
You don't have to read this but in case you think I'm mistaken, there is more detail in the following website under the heading 'Using the Method execute':
http://docsrv.sco.com/JDK_guide/jdbc/getstart/statement.doc.html#1000107
Sounds reasonable. But does not your example code prove that this is not what happens for the database and driver that you are using?
Myself I dont trust update counts at all since, in my experience some databases do not return them. And per other reports sometimes they don't return the correct value either.
So there are two possibilities - your code is wrong or the driver/database does not do it. For me I would also question whether in the future the driver/database would continue to behave the same if you did find some special way to write your SQL so it does do it. And of course you would also need to insure that every proc that needed this would be written in this special way. Hopefully not too many of those.
So this functionality is built into java but is not in common use amongst programmers. My java class did successfully execute a stored proc which Selected from and then finally Updated a table. My code displayed the contents of the Select query and told me how many rows were affected by the update.
It isn't "built into java". It isn't built into jdbc either. If it works at all then the driver and by proxy the database are responsible for it. I suspect that you would be hard pressed to find anything in the JDBC spec that requires what that particular link claims. I believe it is difficult to find anything that suggests that update counts in any form are required.
So you are left with hoping that a particular driver does do it.
I suppose it is rare that you would want to do things this way. Returning rowcounts in OUT parameters would be easier but I want my code to be modular enough to cover the situation where a statement may return more than one ResultSet object, more than one update count, or a combination of ResultSet objects and update counts. The sql may need to be generated dynamically, its statements may be unknown at compile time. For instance a user might have a form that allows them to build their own queries...
Any time I see statements like that it usually makes me a bit uncomfortable. If I am creating data layers I either use an existing framework or I generate the code. For the latter there is no generalization of the usage. Every single operation is laid out in its own code.
And I have in fact created generalized frameworks in the past before. I won't do it again. Benefits of the other idioms during maintenance are too obvious.

I think I will just consolidate this data into one set in a stored proc.

Generating CSV file using java/ stored proc

Hi Folks,
I am using Oracle 11g DB
My requirement is that I have to generate a CSV file which has customer details. Each value that is comma separated comes from different set of SQL queries. I want to write a stored procedure along with java code to acieve this. How do I go about it? Should I return multiple cursors from my stored proc and iterate from the java side to create the CSV file? Any other suggestions?
Thanks
Vishal

Other suggestions? Yes - don't reinvent the wheel - it has already been created.
1. Tom already wrote such a proc and published it many years ago. See this AskTom thread
http://asktom.oracle.com/pls/asktom/f?p=100:11:::::P11_QUESTION_ID:235814350980
2. See BluShadow's link from the '5. How do I read or write an Excel file?' question in the FAQ at the top of the sql and pl/sql forum
SQL and PL/SQL FAQ
3. Use a sql developer query like 'select /*csv*/ * from emp
4. Search the sql and pl/sql forum for csv and use of the many threads that already answer this.

Using Oracle Stored Procedure to call a webservice

Hi,
I am using this version of Oracle:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
Requirement: I have to write a stored procedure that calls a webservice and get the result from webservice and show it on sqlplus.
I have read some articles, and am confused as to where to start. I have come across UTL_DBWS and UTL_HTTP. But to use them, I have to set up my database accordingly allocating pool size etc.
Is there an alternative?
I am reading through a lot of stuff, but I am honestly not getting a hold of anything. Please advice, how I can go step by step.
Thank you!!

Thank you!!don't use Oracle to complete any non-DB related task.
while a shovel is a great tool for producing a hole in the ground,
it is sub-optimal when the wrong end of the shovel is used to move the dirt.
You are using the "wrong end" of Oracle.

Return String from Oracle stored proc using Excel 2003 VBA

Hi to everyone,
I've got a problem that remains unsolved for many days. I am trying to return a value of an oracle stored procedure using Excel VBA. It might seem trivial, however it's not for someone, who has never done it before...
OS: Win XP SP3
Excel 2003
Ora Client: 11g
By trying different things I have noticed, that I could have troubles with the ODBC-connection. Maybe I am not using the right one. To store data returned from select statements I have an ODBC-Connection (Driver: Oracle in XE), which works perfectly, e.g.:
Sub Extract_Data()
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim db_name, UserName, Password As String
cn.Open db_name, USerName, Password
sql_statement = "SELECT some_text FROM some_table"
Set rs = cn.Execute(sql_statement)
rs.MoveFirst 'jump to the first entry in the data list
Row = 2
While Not rs.EOF
'save the data to a worksheet
ip.Cells(Row, 2) = rs(0).Value
Row = Row + 1
rs.MoveNext
Wend
End Sub
Now I need to execute a stored procedure to return a semi-colon delimited string.
I have tried the following:
Public Sub obj_class()
Dim cn As New ADODB.Connection
Dim strSQL, cn As String
Dim adoCMD As ADODB.Command
Dim adoRS As ADODB.Recordset
Set wb = Excel.ActiveWorkbook
Set ih = wb.Sheets("InfoSheet")
cn.Open db_name, UserName, Password
Set adoCMD = New ADODB.Command
With adoCMD
.ActiveConnection = cn
.CommandText = "S#mdb$stg_da_extr_util.get_all_classes_of_classif"
.CommandType = adCmdStoredProc
.Parameters.Refresh
'------ and here comes the error saying:
'------ could not find the object in the collection corresponding to the name or ordinal reference requested by the application
.Parameters("i_caller").Value = "'STG_DATA_REQUEST'"
.Parameters("i_obj_classif_id").Value = 120
Set adoRS = .Execute()
End With
End Sub
I did asked on the forum:
http://www.access-programmers.co.uk/forums/showthread.php?p=1241667#post1241667
but unfortunately without success.
Could it be, that my ODBC-connection is wrong? When debugging the connection string, I find the Provider=MSDASQL5.1.
I have moderate knowledge in VBA, but absolutely a newbie with Oracle DB. Is there any source of information that can help solving this issue? Looking forward to hearing from you, as I am almost giving up... ;(

My VBA is super rusty. Does that error come after Parameters.Refresh, or after .Parameters("i_caller").Value = "'STG_DATA_REQUEST'"?
If it's the second one, you'll need the definition of the stored procedure so you can see what parameters it's expecting. That'd mean you're getting something wrong with the names.

Any way to return NULL using MIN

I need to return NULL when select the MIN of a column that has vales and NULLs.
Any ideas?

Try the syntax shown in RESULT_2 below.
set null "(null)"
with t as
select 'a' as group_key, null as val from dual union all
select 'b' as group_key, null as val from dual union all
select 'b' as group_key, 1    as val from dual union all
select 'c' as group_key, 3    as val from dual
select
group_key ,
min( val ) result_1 ,
min( val ) keep (dense_rank first order by val nulls first) result_2
from t
group by group_key ;
G   RESULT_1   RESULT_2
a (null)     (null)
b          1 (null)
c          3          3--

Can you refine people search results using a SharePoint 2013 search service application connected in SharePoint 2010?

We have an SP2010 farm which is now using some of the service applications from an SP2013 farm, including the search, managed metadata and user profile. This is part of an upgrade programme of work which will involve upgrading infrastructure and
then gradually the sites, and this is seen as one way to minimise the impact.
So, the SP2010 search results are being generated by the SP2013 which is indexing the SP2010 content. The initial results appear fine, however, the refiners in the people results for Job Title and Department are no longer working. We are receiving
a 404 page not found, even though the page is there as was working before.
If we compare the URL generated in SP2010 for refining results to an OOTB SP2013 search centre site, there is clearly a big difference to the format. Example below is where LastName is Smith and then refined where Department is HR.
SP2010 URL which now gives a 404 error:
http://intranet2010/search/pages/peopleresults.aspx?k=LastName%3Asmith&r=%22owstaxIdSPShDepartment%22%3D%23832e3479%2Dd168%2D4620%2Dac69%2D9b00a4c4205b%3A%22HR%22
OOTB SP2013 URL:
http://intranet2013/search/pages/peopleresults.aspx?k%3Asmith#Default=%7B%22k%22%3A%22smith%22%2C%22r%22%3A%5B%7B%22n%22%3A%22Department%22%2C%22t%22%3A%5B%22%5C%22%C7%82%C7%824335%5C%22%22%5D%2C%22o%22%3A%22and%22%2C%22m%22%3Anull%2C%22k%22%3Afalse%7D%5D%7D
I've looked at the URL decoded versions so can see how the query is built up.
Any ideas? Is this even possible?

All working now. Turns out there was an entry in the web.config which was causing issues.
<denyQueryStringSequences>
<add sequence="ID" />
</denyQueryStringSequences>
Seems IIS is denying something in the query string. We removed the whole section as was not needed.

Thanks to a colleague who spotted this; I would've never of thought to check the web.config for something like this.

Using Oracle Stored Proc as Data Source for PowerBuilder Data Window Object

Hi,
I'm trying to use an Oracle stored procedure as the data source for a PowerBuilder data window object. I'm using the following (which is a variation of an example given on Sybase's web site, with the appropriate database/column name changes and use of %TYPE):
======================
CREATE OR REPLACE PACKAGE pkg_dw_sp_example
AS
TYPE typ_example_rec1 IS RECORD(
v_comcodsa st_sa.comcodsa%TYPE,
v_comnamsa st_sa.comnamsa%TYPE,
v_cocitysa st_sa.cocitysa%TYPE);
TYPE cur_example_cur1 IS REF CURSOR;
RETURN typ_example_rec1;
END;
======================
CREATE OR REPLACE PROCEDURE sp_dw_example1
(arg_teamid IN st_sa.comcodsa%TYPE,
cur_team IN OUT pkg_dw_sp_example.cur_example_cur1)
AS
BEGIN
OPEN cur_team FOR
          SELECT comcodsa,
          comnamsa,
          cocitysa
          FROM st_sa
          WHERE st_sa.comcodha = arg_teamid;
END sp_dw_example1;
======================
The package is created okay, but the procedure is saved with compilation errors. Unfortunately, Oracle does not indicate what the errors are (great product), so I have no idea what it is complaining about.
Questions:
1) Can anyone point me to/or provide a better example?
2) The examples in books I have seen all would have declared the procedure in the package specification - is the above valid?
3) This is a PowerBuilder specific question, but if the package does not show up in the stored procedure list when creating a data window object, how does one use it as a data source?
Oracle 8.1.7
PowerBuilder 8.0.1
Thanks,
Ed Holloman

1) Everything looks fine with your code. You did not mention the environment you are compiling your code in, but if it is SQL*Plus, you can type 'show errors' after the compile and it will list the errors and line numbers for you.
2) You can include the procedure in the package - in which case you would have a procedure declaration in the spec and the actual procedure in the body. You would no longer include the 'create or replace' - the declaration and procedure would just start with 'procedure'. The spec would look include:
PROCEDURE sp_dw_example1
(arg_teamid IN st_sa.comcodsa%TYPE,
   cur_team OUT cur_example_cur1);Note the removal of the package reference (since we are now IN the package) and the second parameter is just OUT instead of IN OUT.
3) Not much, but I know that in PB8, our developers have said they have visibility now to the package when creating a DW - something they didn't have in PB7. Previously, we had to create a dummy standalone procedure that they would select and they would later modify the code to include the package prefix.
Hope this helps a bit.
