Dynamic Initialization of PL/SQL collection ...

Hi,
I trying to initialize table type using execute immediate but get the following error:
DECLARE
     TYPE SCHEMA_LIST IS TABLE OF ALL_USERS.USERNAME%TYPE;
     L_SCHEMAS SCHEMA_LIST;
BEGIN
EXECUTE IMMEDIATE ' BEGIN :b1 := SCHEMA_LIST ('''||FN_GET_CONFIGVALUE ('PRAM1')||'''); END; ' USING OUT L_SCHEMAS;
FOR L_IDX IN L_SCHEMAS.FIRST..L_SCHEMAS.LAST LOOP
DBMS_OUTPUT.PUT_LINE
               L_SCHEMAS(L_IDX)
END LOOP;
END;
ERROR at line 7:
ORA-06550: line 7, column 138:
PLS-00457: expressions have to be of SQL types
ORA-06550: line 7, column 9:
PL/SQL: Statement ignored
The function FN_GET_CONFIGVALUE ('PRAM1') which takes one input parameter would return a comma seperated list which I would then initialize to the table type.
Any Idea ?
Thanks !
Pat

Patza,
It seems one cannot initialize( i.e. "USING" and "RETURNING" ) index-table, record and boolean-type expressions in dynamic SQL, only true PL/SQL expressions can be used. Since you are trying to initialize a table type, this is where the problem lies. If I may suggest, perhaps accepting the output in some alternative way (i.e. variables or somesuch) might fix the problem.
Kindest regards,
Stefan

Declare and initialize a varray of collection Object and pass it as OUT Par

Hi ,
How to declare and initialize a varray of collection Object and pass it as OUT Parameter to a procedure.
Following is the Object and VARRAY Type 's I have created and trying to pass the EmployeeList varray type variable as an OUT parameter to my stored procedure, but it is not working. I tried different possibilities of declaring and initializing the varray type variable but it did not work. Any help would be appreciated.
CREATE TYPE Employee IS Object

10g: parallel pipelined table func. using table(cast(SQL collect.))?

Hi,
i try to distribute SQL data objects - stored in a SQL data type TABLE OF <object-Type> - to multiple (parallel) instances of a table function,
by passing a CURSOR(...) to the table function, which selects from the SQL TABLE OF storage via "select * from TABLE(CAST(<storage> as <storage-type>)".
But oracle always only uses a single table function instance :-(
whatever hints i provide or setting i use for the parallel table function (parallel_enable ...)
Could it be, that this is due to the fact, that my data are not
globally available, but only in the main thread data?
Can someone confirm, that it's not possible to start multiple parallel table functions
for selecting on SQL data type TABLE OF <object>storages?

I posted it to newsgroup comp.databases.oracle.server.
(summary: "10g: parallel pipelined table functions with cursor selecting from table(cast(SQL collection)) doesn't work ")
But i didn't get a response.
There i also wrote some background information about my application:
-------------------- snip ---------------------------------------------
My application has a #2 steps/stages data selection.
A 1st select for minimal context base data
- mainly to evaluate for due driving data records.
And a 2nd select for all the "real" data to process a context
(joining much more other tables here, which i don't want to do for non-due records).
So it's doing stage #1 select first, then stage #2 select - based on stage #1 results - next.
The first implementation of the application did the stage #1 select in the main session of the pl/sql code.
And for the stage #2 select there was done a dispatch to multiple parallel table functions (in multiple worker sessions) for the "real work".
That worked.
However there was a flaw:
Between records from stage #1 selection and records from stage #2 selection there is a 1:n relation (via key / foreign key relation).
Means, for #1 resulting record from stage #1 selection, there are #x records from stage #2 selection.
That forced me to use "cluster curStage2 by (theKey)".
Because the worker sessions need to evaluate the all-over status for a context of #1 record from stage #1 and #x records from stage #2
(so it needs to have #x records of stage #2 together).
This then resulted in delay for starting up the worker sessions (i didn't find a way to get rid of this).
So i wanted to shift the invocation of the worker sessions to the stage #1 selection.
Then i don't need the "cluster curStage2 by (theKey)" anymore!
But: i also need to do an update of the primary driving data!
So the stage #1 select is a 'select ... for update ...'.
But you can't use such in CURSOR for table functions (which i can understand, why it's not possible).
So i have to do my stage #1 selection in two steps:
1. 'select for update' by main session and collect result in SQL collection.
2. pass collected data to parallel table functions
And for 2. i recognized, that it doesn't start up multiple parallel table function instances.
As a work-around
- if it's just not possible to start multiple parallel pipelined table functions for dispatching from 'select * from TABLE(CAST(... as ...))' -
i need to select again on the base tables - driven by the SQL collection data.
But before i do so, i wanted to verify, if it's really not possible.
Maybe i just miss a special oracle hint or whatever you can get "out of another box" :-)

Dynamic table pulled from SQL database, Need to Search

My table results are not static, they are pulled into a
dynamic table from a SQL database. Each table displays 10 records
with an option at the bottom to display additional records
(next/previous), for my query. I also have an option set up to
allow users to click for a detail view of a record in the table. If
the table data was static, I would be able to set up a search
option and a results page for it, but I'm dealing with dynamic data
on an .ASP page. I'd like to set up a search box to limit the
records displayed in the table. I haven't found any code samples
that are designed for dynamic data.
Here is a copy of the code from my table.

Hi,
I think the code on this URL will get you the solution

Binding parameters to dynamic VO with PL/SQL API call with no where clause

Hi all,
I am required to change exisiting queries to queries with "bind" parameters. Some of our VOs are dynamic and with PL/SQL api calls like below:
String stmtStr = "selectXXX_API_UTILS.chk_urg_since_last_prg("
+ projectId + "," + PPCId + ",'XYZ_TASKS'," + taskId+ ")"
+" from dual ";
ViewObject tmpVO = transaction.createViewObjectFromQueryStmt(stmtStr);
In this regard, I am unsure how to bind the PPCId and taskId parameters to the VO. setWhereClauseParams() would not work here as there is now where clause.
Thanks in advance,
Srini

In case of preparedStatement, we mention bind parameters to be passed using "?". Then we pass paramters sequencially.
But in the your case following is enough:
int projectId = 100 ; (hardcoding values for example)
int taskId = 500 ;
String stmtStr = "selectXXX_API_UTILS.chk_urg_since_last_prg("
+ projectId + "," + PPCId + ",'XYZ_TASKS'," + taskId+ ")"
+" from dual ";

Creating Crystal Reports Dynamically from an incoming SQL query

Hi,
I have a requirement where a sql query will be entered by the user in a text box and in the back end java code, i have to create a crystal report dynamically based on that sql query and show it in the crystalviewer object.
For example if the user writes "select x,y from xtable ", i should be able to create a report with 2 fields, and if the user says "select x,y,z from xtable" then i should be able create and show a report with 3 fileds...thsi report creation should be done in the click event.
Is this possible in java? I have found something similar in .NET... pls have a look at this
http://vb.net-informations.com/crystal-report/dynamic_crystal_report_from_sql_query_string.htm
Thanks,
Preethi

Hi Preethi,
Can you please share the steps with me? I am also looking for dynamic SQL being applied to the crystal report.
Thank you so much for your help in advance.

Using Dynamic VIEW better pl/sql ?

Hi,
Would like to know your suggestion,
Currently i need to process 5 tables and put the data into a new single Table.
The number of Rows are many, 1000000 and could be even more.
Now i am planning to Create a View from the 5 Tables and then
form the View i am planning to do the Processing and
after which i will put the processed data into the newly created table.
Alternatively i was thinking of having a Collection of Objects(Nested Table) instead of VIEW,
since the number of rows which need to be processed are more i felt this would not be a better option.
Can we go-ahead creating VIEW dynamically, Or is there any better design Solution that you can think of ?

Alex

Help with dynamic statement returning values into collection

Hi All
I am trying to use dynamic statement to return values into a collection using the returning clause. However, I get an ORA-00933 error. Here is a simple setup:
create table t(

    id_batch varchar2(30),
    date_created date,
    constraint t_pk primary key ( pk )
create or replace type num_ntt is table of number;
create or replace type vc2_ntt is table of varchar2(30);
create or replace
package pkg
as
type rec is record(
      pk        num_ntt,
      id_batch vc2_ntt

but I am working with dynamic statement and returning multiple fields into a collection.And using an INSERT...SELECT statement combined with a RETURNING INTO clause still does not work. Whether it's dynamic SQL or not: it doesn't work. The link describes a workaround.
By the way, I don't see why you are using dynamic SQL here. Static SQL will do just fine. And so you can literally copy Adrian's setup.

How do I pass selected values from dynamic LOV to Command SQL in Oracle

My environment:
Crystal 11
Oracle 10
I've created and tuned a SQL script for a report. In the Database Expert, I've copied the SQL into a Command. I've modified the Command to create 3 parameters.
I need help with the following:
1) How do I create a dynamic, cascading LOV and associated prompt group for the three parameters defined in the Command?
2) How do I pass the user selected valueS from the prompt group into the Command SQL as limits applied to the query executed against the database?

I have the same problem with same environment .
The main report is having a 2 level cascading dynamic parameters.
I created a sub report with a command as below.
*select * from (*
select DATUM,MSEC,CNT,B1_NAME,B2_NAME,B3_NAME,ELEM_NAME,INFO_NAME,m.INFOTYPE,V.NAME,rank()
over (partition by B1_NAME,B2_NAME,B3_NAME order by DATUM desc ,MSEC desc,CNT desc) currentRank
from MESSAGES m,INTYDE i,VANAME v
where DATUM <=SYSDATE and trim(B1_NAME)='{?B1Name}'
and trim(B2_NAME)='{?B2Name}'
and m.INFOTYPE=i.INFOTYPE
and i.VALUE_NAME_NUMBER = v.VALNUM) where currentRank=1
I needs to pass cmbination of B1Name and B2Name from main report. I created a formula like
formula=Join({?B1Name},{?B2Name}),'|'); But this is showing some error.
and How I will substitute this in my command . As I new to Crystal XI help expected.

Problem setting a hidden item value when button clicked with dynamic action or pl/sql process

Apex 4.1
Oracle 11g
I have a page that consists of a main region and several sub regions. I have a pl/sql process in After Header SET_DISPLAY(:P400_DISPLAY :='MAIN';)
Three subregions have a contional display where P400_DISPLAY = STORE. This works in hiding the sub regions.
Now I want to change the P400_DISPLAY value to STORE to show the subregions when I hit a button.
I tried creating a dynamic action for on click of the add button but get the following error:
The selected button uses a 'Button Template' that does not contain the #BUTTON_ID# substitution string
I went to the templates and found:
Substitution Strings
Substitution strings are used within sub templates to reference component values. This report details substitution string usage for this template.
Substitution String

From
Description
#LINK#

Template

#JAVASCRIPT#

#LABEL#

#BUTTON_ATTRIBUTES#
No
Button Attributes
#BUTTON_ID#
No
Generated button ID will be either the button's Static ID if defined, or if not will be an internally generated ID in the format 'B' || [Internal Button ID]
I then tried creating a page process, pl/sql, :P400_DISPLAY :='STORE'; when the appropriate button is pressed. The button action is submit page. However, it does not change the P400_DISPLAY value and the subregions stay hidden.
Suggestions please on how to fix the template or change the P400_DISPLAY value?

The root issue is that, although you change the value of your page item, it isn't visible to other areas of the page until it is in the session. So, any other action based on the value of your page item; the visibility of a control, a report based on the item's value, etc. will all be unaffected by changing the value of the page item until it has been changed in the session. Even after this the items are stored in the session, you must thereafter do something to cause the value to be reevaluated. To see the effect of this, observe that your page loads and evaluates the value of your page item, it sees that is "MAIN" and hides the regions. However, it doesn't reevaluate them after this.
So; your choices to get this value set in the session are to either Submit the page, or use JavaScript to set the value in the session. If you use the latter of these, you'll have to do some further work to cause the visibility tests to be re-run, So, let's stick with with the submit method.
What you've done above sounds correct for this but, there are a lot of decisions you could have made that might have caused things not to happen in the correct sequence.
Firstly, let's confirm that what I describe above is your problem. From the development environment, load the page, click the button to change the value and submit. Now, click the link labelled Session. Is it still set to MAIN? If so; this is your issue.
Let's start with the your After Header computation. Did you set it to *only* run if the current value of your page item is NULL??? If not, that's your problem.
Load Page -> Item set to 'Main' by Computation -> Click Button -> Item set to STORE -> Submit -> Load Page -> Item set to 'Main' by Computation
See the problem?
Assuming this isn't the issue, you created a Branch to the same page, right? What is your process point for the Branch? Is it *After* Validation, Computation etc? Because if not, you aren't changing the value before the submit happens.
I bet it is the first issue but, take a look at these.
Cheers,
-Joe

Dynamic header creation using SQL

Hi Gurus,
I need your help again. I have a query which uses a date parameter to populate a report. The report pulls out data from the user entered date to minus eleven months. The report counts totals calls registered each month. I have the query working fine but I need help in populating the header.
For ex - suppose I run the query on todays date (18-Jan-2012)
The report header will be -
Jan Feb Mar Apr ....Dec
But I want the header to be populated in the following format -
Jan 2012 Feb 2011 Mar 2011 Apr 2011....Dec 2011
And for ex if I run the report for a future date say (21-May-2012)
The header will be in the following format -
Jan 2012....May 2012 Jun 2011 Jul 2011 .......Dec 2011.
Please let me know if I can populate the header using SQL. Any help is greatly appreciated.

Hi Tenacious,

I want the header to be populated in the dynamic format with the year value concanated to the Month column.My script does that; you can look one more time at the output in my first post, and also in my second post.
And if you want another example, when we replace 18-Jan-2012 by 21-May-2012, we have the following:

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.

Dynamic Dimesion Building using SQL Interface

I am attempting to use SQL Interface in Essbase 6.5 to dynamically build the account dimension from a PeopleSoft tree. The view works fine in SQL worksheet, but the last UNION statement does not work using the SQL interface. Here is the SQL that is generated: [SELECT * FROM ps_n_pre_acc_vw WHERE 1 = 1 order by 6,4,5,3] is generated. Here is the view:SELECT B.TREE_NODE AS PARENT , A.TREE_NODE AS CHILD , (A.TREE_NODE||' : '||C.DESCR) , b.tree_node_num AS num , a.tree_node_num AS c_tree_node_num , 'A' AS ord FROM SYSADM.PSTREENODE A , SYSADM.PSTREENODE B , SYSADM.PS_TREE_NODE_TBL C WHERE A.TREE_NAME = 'PRE_CUBE' AND A.SETID = 'NW' AND A.EFFDT = ( SELECT MAX(EFFDT) FROM PSTREELEAF WHERE TREE_NAME = 'PRE_CUBE') AND A.TREE_NAME = B.TREE_NAME AND A.SETID = B.SETID AND A.EFFDT = B.EFFDT AND A.PARENT_NODE_NUM = B.TREE_NODE_NUM AND A.TREE_NODE = C.TREE_NODE AND A.SETID = C.SETID AND C.EFF_STATUS = 'A' AND C.EFFDT = ( SELECT MAX(EFFDT) FROM SYSADM.PS_TREE_NODE_TBL X WHERE C.TREE_NODE = X.TREE_NODE AND C.SETID = X.SETID) UNION SELECT B.TREE_NODE AS PARENT , (A.RANGE_FROM||' : '||DESCR) AS child , A.RANGE_FROM , b.tree_node_num AS num , a.tree_node_num AS c_tree_node_num , 'B' AS ord FROM SYSADM.PSTREELEAF A , SYSADM.PSTREENODE B , SYSADM.PS_GL_ACCOUNT_TBL C WHERE A.TREE_NAME = 'PRE_CUBE' AND A.SETID = 'NW' AND A.EFFDT = ( SELECT MAX(EFFDT) FROM PSTREELEAF WHERE TREE_NAME = 'PRE_CUBE') AND A.TREE_NAME = B.TREE_NAME AND A.EFFDT = B.EFFDT AND A.SETID = B.SETID AND A.TREE_NODE_NUM = B.TREE_NODE_NUM AND C.SETID = A.SETID AND A.RANGE_FROM = C.ACCOUNT AND C.EFFDT = ( SELECT MAX(EFFDT) FROM SYSADM.PS_GL_ACCOUNT_TBL X WHERE C.ACCOUNT = X.ACCOUNT AND c.setid = x.setid) UNION SELECT B.TREE_NODE AS PARENT , (D.ACCOUNT||' : '||DESCR) AS child , D.ACCOUNT , b.tree_node_num AS num , a.tree_node_num AS c_tree_node_num , 'B' AS ord FROM pstreeleaf a , pstreenode b , PS_GL_ACCOUNT_TBL D WHERE a.tree_name = 'PRE_CUBE' AND a.effdt = '01-JAN-2001' AND A.SETID = 'NW' AND A.RANGE_FROM <> A.RANGE_TO AND A.TREE_NAME = B.TREE_NAME AND A.SETID = B.SETID AND A.EFFDT = B.EFFDT AND A.TREE_NODE_NUM = B.TREE_NODE_NUM AND D.ACCOUNT BETWEEN A.RANGE_FROM AND A.RANGE_TO AND D.SETID = 'NW' AND D.EFFDT = ( SELECT MAX(EFFDT) FROM PS_GL_ACCOUNT_TBL X WHERE D.ACCOUNT = X.ACCOUNT AND D.SETID = X.SETID)I created a view from the last union section of the SQL and Essbase returns a zero rows found error, although when I ran the view in SQL worksheet I was able to get rows returned. Any ideas on why the view does not return the expected results in Essbase?

before your query do:
<cfsavecontent
variable="emailmessagebody"><cfinclude
template="#mancbPath#/mancb_body.cfm"></cfsavecontent>
then in your query instead of using '<cfinclude ...>'
use
'#emailmessagebody#'
