Cast DBMS_SQL.NUMBER_TABLE to another pl/sql table-of-number type?

Using dynamic SQL, I am bulk-collecting two numeric fields into two tables of number. This works fine, the tables are DBMS_SQL.NUMBER_TABLE.
I am trying to feed an API that takes two table of these numbers, but its parameter types are different. Both are identical definitions to DBMS_SQL.NUMBER_TABLE, i.e., TABLE OF NUMBER INDEX BY BINARY_INTEGER.
I don't want to duplicate or copy 2500-7500 records to do this, but I can't find a way to use the api's table-of-number with DBMS_SQL.DEFINE_ARRAY. Nor can I use DBMS_SQL.NUMBER_TABLE with this API. I've tried a few CAST phrases, but it won't compile.
Can someone give me a suggestion here? I'd hate to set up a loop to copy the data from one table to another.
Thanks,
Andrew Wolfe

Dikshit,
This is a volunteer forum. Getting impatient after 15 minutes is not especially nice behavior on your part.
Likely you pass the parameter the same way as you initialize a table inside the procedure, so (7141,7256,8913) etc.
In the worst scenario you would need to set up an anonymous block with a collection of type dbms_sql.number_table and initialize that collection.
But of course you can always verify this in the PL/SQL documentation.

Another problem, sql table creating, no respond

What im trying to do is create table mysql table. My code looks like this:
import java.sql.*;
public class HelloWorldApp {
     public static Connection con = null;
     public static Statement stmt;
     public static void createConnection() {
          try {
               String serverName = "127.0.0.1";
               String mydatabase = "java";
               String url = "jdbc:mysql://" + serverName + "/" + mydatabase;
               Class.forName("com.mysql.jdbc.Driver").newInstance();
               con = DriverManager.getConnection(url, "root", "");
               stmt = con.createStatement();
          } catch (Exception e) {
               e.printStackTrace();
     public static void createTable(String tableName) {

               createConnection();
               createTable("test");
}And the problem is, that after it prints "Hello world!" nothing hapands, its even not exits if i remove "pause" from run.bat. Anyway im stuck, please help.

A few notes on your code:
* Don't import everything from a given package, only what you need.
* Your tableName variable is not being used. You are using tableName literally in your variable named sql.
* This variable is not being used as you think
public static Statement stmt;You are creating a local variable with the same name in the the createTable method.
* You should always close your connections and statements. Read the API docs for each of these classes.
* Don't make everything static. Use instance variables and create an instance of your class with the new operator.
Are you getting any sort of error message printed to the shell? You could try adding more System.out.println() calls to see what's going on.

Getting the value from a PL/SQL table

I have a view ( VIEW$TEMP ) that is building on runtime using FormsDDL.All its fields are varchar2 but the columns are not predefined.
In a Package (P) Specification I have define a PL/SQL Table like that:
type tt is table of view$temp%rowtype index by binary_integer
vTable tt;
I have opened a cursor and fetch the VIEW$TEMP into vTable.
Now I Need a function
F( vRow in number, vField varchar2 ) return varchar2
that take as arguments a row of the vTable and the Field name as varchar and returns to me the value in the table. This must be to the server(so I can not use copyto).
Any help will be helpful.

Hi,
Excuse me, but, if, as I understood, the structure of the view changes at runtime, that would make the any stored procedure invalid, so that, before any execution, the given stored procedure would need to be compiled. Is it not so?
As for that function you need, you simply have to use dbms_sql (if that could be called simple).
Personally, I'd put the problem someway else and use different data structures and views.
Yet, please, don't get me wrong, I'd like to know more about this particular solution you are willing to implement.

Pl sql tables to VB

Hi all,
We have ORACLE 7.3 as server and VB 6.0 as the client . We have a procedure that returns PL/SQL table as an out parameter.When the procedure returns a single dimensional PL/SQL table , the front end does not have any problem in getting the output. When the same package tries to return a multidemensioanl PL/SQL table to front end we get an error message in the front end saying that the provider does not support PL/SQL tables or records.The package creates the PL/SQL table as follows
TYPE emp_inf is RECORD
(empno varchar2(7),
ename varchar2(50));
TYPE emp_inf_table is table of emp_inf
INDEX BY BINARY_INTEGER;
The procedure works fine on the server side.Any ideas why we are getting that error message. We are using ADO in the front end. Any other way of doing the above.
Thanks in advance,
Jay.

Function returning pl/sql table of dynamic structure

Hi,
I use oracle11g/windows platform.
I have a requirement to be coded like this:
A function to return pl/sql table(cant use ref cursor) whose columns varies everytime it runs i.e.,
means
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000))
type pl_tab is table of pl_tab_type
func f return pl_tab
as
end;
note : pl_tab_type will vary for each run of function f
i.e.,for example, pl_tab_type can be changd to as follows:
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000),col3 varchar2(1000))
how to return pl/sql table of dynamic type from func, thanks for help in advance.

How to type cast PL/SQL table to REF cursor?

any one knows how to CAST PL/SQl table to Ref cursor?
eg
procedure some_name(r_out out sys_refcurosr)

type t is table of tab%ROWTYPE;
my_type t;
begin
select * bulk collect into my_type from tab;
r_out := my_type; -- need help here..
end;
it's 10g

ref cursor is pointer to result set. You can not cast to PL/SQL table.
1 create or replace procedure some_name(r_out out sys_refcursor)
2 IS
3 begin
4 OPEN r_out for select * from emp;
5* end;
SQL> /
Procedure created.

Error while retrieving data from PL/SQL Table using SELECT st. (Urgent!!!)

Hi Friends,
I am using Oracle 8.1.6 Server, & facing problems while retrieving data from a PL/SQL Table:
CREATE or REPLACE PROCEDURE test_proc IS
TYPE tP2 is TABLE of varchar2(10); --declared a collection
dt2 tP2 := tP2('a','b','c');
i NUMBER(8);
begin
SELECT COUNT(*) INTO i FROM TABLE(CAST(dt2 as tP2));
DBMS_OUTPUT.PUT_LINE('**'||i);
end;
While executing the above procedure, I encountered foll. error:
ERROR at line 1:
ORA-00600: internal error code, arguments: [15419], [severe error during PL/SQL execution], [], [],
ORA-06544: PL/SQL: internal error, arguments: [pfrrun.c:pfrbnd1()], [], [], [], [], [], [], []
ORA-06553: PLS-801: internal error [0]
Can anyone please help me, where the problem is??
Is it Possible to retrieve data from PL/SQL TABLE using SELECT statement? & How ?
Thanks in advance.
Best Regards,
Jay Raval.

Thanks Roger for the Update.
It means that have to first CREATE TYPE .. TABLE in database then only I can fire a Select statement on that TYPE.
Actually I wanted to fire a Select statement on the TABLE TYPE, defined & declared in PLSQL stored procedure using DECLARE TYPE .. TABLE & not using CREATE TYPE .. TABLE.
I was eager to know this, because my organization is reluctant in using CREATE TYPE .. TABLE defined in the database, so I was looking out for another alternative to access PL/SQL TABLE using Select statement without defining it database. It would have been good if I could access a PLSQL TABLE using Select statement Declared locally in the stored procedure.
Can I summarize that to access a PL/SQL TABLE using SELECT statement, I have to first CREATE TYPE .. TABLE?
If someone have any other idea on this, please do let me know.
Thanks a lot for all help.
Best Regards,
Jay Raval.
You have to define a database type...
create type tP2 is table of varchar2(10)
CREATE OR REPLACE PROCEDURE TEST_PROC
IS
dt2 tP2 := tP2('a','b','c');
i NUMBER(8);
begin
SELECT COUNT(*) INTO i FROM TABLE(CAST (dt2 AS tP2));
DBMS_OUTPUT.PUT_LINE('**'||i);
end;
This will work.

Pull data from SQL Table and display it in mail

I have a requirement to pull the data from SQL table and send it in email. Currently I am sending the hard coded info in email but is it possible to pull some data from SQL Table and than format it and send it across in the same email?
Can you guide me with steps on this.
Neil

There are several ways to do this. First is to populate a file in a data flow and then send that as an attachment in the send mail task.
As far as including the results in the email body this becomes a bit trickier. To use a variable you would need to use an SSIS variable type of
Object, this is similar to a collection in .NET. The problem once the object is populated is that it isn't like a readable result set, but again more like an array or a collection. There is no native method to take the object variable and
specify .ToString() or cast its results as text. You would need to iterate through each row and append it to another variable of type string, this could be done with a script task or ForEach container.
Also you mentioned formatting the results. What type of formatting were you looking for. A limitation of the SMTP send mail task is that the message body doesn't support HTML so if you were looking at creating a table within the mail body you
would have to use a script task or a custom component

Joining java array with SQL table in a stored procedure

Hey,
I am calling a pl/sql stored procedure from a java program passing two arrays (employees) and (departments) as parameters to the procedure. Within the procedure I have stored the arrays in a table of records like this:
type t_emp_type is record (employee_id number, department_id number);
type t_emp_tbl_type is table of t_emp_type index by binary_integer;
Where all elements in employees are stored in the employee_id column and departments are stored in the department_id column. So basically I've got a table like:
l_employee_tbl t_emp_tbl_type;
Looped through the arrays and stored the data like:
for i in 1..p_employees.count loop
l_employee_tbl(i).employee_id := p_employees(i);
l_employee_tbl(i).deparment_id := p_departments(i);
end loop;
Now I would like to compare my l_employee_tbl with a SQL table in the database. Basically I would like to join my l_employee_tbl table with a SQL table named departments on department_id, returning all department_id:s that was not found in table departments.
However, it is not possible to select from a user-defined table type. I have also tried to use the table() function and to cast l_employee_tbl, but found out it can't be done with records. And I would really like to use records or some other type where define my PL/SQL data. I know that you should not mix PL/SQL and SQL but in this case I think it is more efficient to try joining these "tables". Does anyone have a solution for this or advice to try something else out? It would be most appreciated.

Now I would like to compare my l_employee_tbl with a SQL table in the database. Basically I would like to join my l_employee_tbl table with a SQL table named departments on department_id, returning all department_id:s that was not found in table departments. Of course, not possible as the SQL engine does not support PL/SQL user defined types. PL/SQL however support user defined SQL types. Which makes SQL defined types a lot more flexible.
However, it is not possible to select from a user-defined table type. I have also tried to use the table() function and to cast l_employee_tbl, but found out it can't be done with records. Never mind SQL and PL/SQL - as a generic programming data structure principle. How do you expect being able to cast an associative array (name-value pairs) to a standard array? The two data structures are very different. So I'm puzzled in how you expect to move a non-scalar name-value pair data structure into a non-scalar value only data structure?
And I would really like to use records or some other type where define my PL/SQL data. Why exactly? If the Java or PL/SQL data structure is populated using SQL data and database data, and wanting to use that data structure in SQL, what is the point? Why pull SQL data into a client data structure at all then - surely it is far more performant and scalable to rather keep that data in the database, and do the joins/selects/filters/etc using SQL?
There is also the issue of scalability of local data structures in PL/SQL. The PL/SQL engine runs inside an Oracle server process, consuming private process memory on the server. The bigger the data structures used in PL/SQL, the more server memory needs to be allocated to that server process. This does not scale. Especially not if 10 or more such server processes are running the same PL/SQL code and each server needs to grab large chunks of server memory.
If the data from Java comes from another source (e.g. keyboard, etc), and you need a means of storing this data server-side for use by PL/SQL and SQL. There are 2 basic choices. PL/SQL arrays for smallish amounts of data - and basing these arrays preferable on SQL data types allowing the array to be used by both SQL and PL/SQL engines. If the amount of data is not smallish, then it should be stored in the SQL engine (database) as that is designed for that exact purpose. And if the data is transient, then a GTT (global temp table) structure can be used (and indexed for optimal access).

Dbms_sql.number_table

In_Message IN emp.dept_id%TYPE := NULL,
In_emp_id IN dbms_sql.Number_Table,
In_LastUpdatedBy IN emp.hire_date%TYPE,

how to execute ??? how to pass the value to IN parameter " In_emp_id"?????

Dikshit,
This is a volunteer forum. Getting impatient after 15 minutes is not especially nice behavior on your part.
Likely you pass the parameter the same way as you initialize a table inside the procedure, so (7141,7256,8913) etc.
In the worst scenario you would need to set up an anonymous block with a collection of type dbms_sql.number_table and initialize that collection.
But of course you can always verify this in the PL/SQL documentation.

Accessing PL/SQL table in SQL query

Hello,
Is it possible to use plain SQL to query PL/SQL table? In my case this table is returned by UTL_HTTP.REQUEST_PIECES function, which is defined as:
create or replace package utl_http is
type html_pieces is table of varchar2(2000) index by binary_integer;
function request_pieces (url in varchar2,
max_pieces natural default 32767)
return html_pieces;
pragma restrict_references (request_pieces, wnds, rnds, wnps, rnps);
Generally, I want to access chunks of external data for comparison without using PL/SQL. Thanks ahead for ideas. Ideally, I need working example because my attempts to use TABLE & CAST failed.

I was going to suggest you could try and create your own wrapper around utl_http and use a database type, but then I remembered this excellent thread which covers it better than I ever could - Billy, hope you don't mind passing on your good work!

PL/SQL TABLE AS A PARAMETER TO PSP

Hello !
In a PSP application one of the pages is retrieving rows more than 10, and the limitation for the same is to display only 10 rows a page. Same can be done using OWA_UTIL but only if you are having a query to pass as one of the parameters.
I'm processing a PL/SQL block and storing the outcome in a PL/SL table. After showing 10 rows of a table on the first screen, would like to pass the PL/SQL table as a parameter to other .PSP so that I can display another set of 10 out there. The calling page is not getting compiled if passed a PL/SQL table as a parameter flashing an error 'number or type mismatch'.

Report from PL/SQL Table

Thanks for answer to my first question. Now I have another problem.
Is there any way to print a report based on virtual table, which is created during some Pl/SQL procedure and can't be easily decribed by Select statement

SELECT FROM PL/SQL TABLE IN ORACLE REPORTS 6I
The requirement is to populate a table and then select from that table in a report. The typical solution is to
populate a database table, but for situations where that is undesirable there is a way to select from a PL/SQL
table.
For example - for each employee we want to populate a PL/SQL table and then select from that table.
I used the following records in the emp table:
INSERT INTO Emp VALUES(123,'Bob','Sales',555,'28-JAN-79',35000,12,30);
INSERT INTO Emp VALUES(321,'Sue','Finance',555,'12-MAY-83',42000,12,10);
INSERT INTO Emp VALUES(234,'Mary','Account',555,'14-AUG-82',33000,12,20);
INSERT INTO Emp VALUES(623,'Joe','Sales',555,'28-JAN-79',35000,12,30);
INSERT INTO Emp VALUES(621,'Jim','Finance',555,'12-MAY-83',42000,12,10);
INSERT INTO Emp VALUES(634,'Jane','Account',555,'14-AUG-82',33000,12,20);
INSERT INTO Emp VALUES(723,'Fred','Sales',555,'28-JAN-79',35000,12,30);
INSERT INTO Emp VALUES(721,'Meg','Finance',555,'12-MAY-83',42000,12,10);
INSERT INTO Emp VALUES(734,'Jill','Account',555,'14-AUG-82',33000,12,20);
=============================================================================================
Step 1: Create a package spec in the report:
PACKAGE pkg_table IS
TYPE t_rec IS RECORD (
field1 NUMBER(6),
field2 VARCHAR2(30));
TYPE t_tab IS TABLE OF t_rec INDEX BY BINARY_INTEGER;
gv_tab t_tab;
FUNCTION populate (
p_empno NUMBER) RETURN NUMBER;
END;
Step 2: Create the package body:
PACKAGE BODY pkg_table IS
FUNCTION populate (
p_empno NUMBER) RETURN NUMBER IS
BEGIN
     gv_tab.DELETE;
     -- populate table as required - for demo purposes put in anything
     FOR lv_ind IN 1..MOD(p_empno,20) LOOP
          gv_tab(lv_ind).field1 := lv_ind;
          gv_tab(lv_ind).field2 := 'row '||TO_CHAR(lv_ind)||' for emp '||TO_CHAR(p_empno);
     END LOOP;
     RETURN gv_tab.COUNT;
END populate;
END;
Step 3: Create the master query:
SELECT empno,
ename
FROM emp
Step 4: Add a formula column CF_populate to the master query that does:
function CF_populateFormula return Number is
-- for each emp fetched this formula will repopulate the PL/SQL table
-- and return the number of records in the table
begin
return pkg_table.populate(:empno);
end;
Step 5: Create the detail query:
-- we need to join this to the master and then ensure that for each
-- empno there are as many records fetched as there will be
-- records in the PL/SQL table
SELECT e1.empno,rownum
FROM emp e1, emp e2, emp e3
WHERE rownum <= :CF_populate
Step 6: Add formula columns to the detail query for each of the fields in the
PL/SQL table we want to display:
CF_Field1:
function CF_field1Formula return Number is
begin
return pkg_table.gv_tab(:rownum).field1;
end;
CF_Field2:
function CF_field2Formula return Varchar2 is
begin
return pkg_table.gv_tab(:rownum).field2;
end;
Step 7: Create the repeating frame and layout items to display the formula columns.
=============================================================================================
The same technique can be used to populate a master query. In a report level formula column
CF_Populate populate the PL/SQL table as required. In the master query we just need the rownum:
SELECT rownum
FROM emp, emp, emp
WHERE rownum <= :CF_Populate
Add the formula columns to display Field1 and Field2.

PL/SQL Table use in report region query

Hello,
I have a package function which return pl/sql table. I want to create a report region based on this pl/sql table. Is it possible to do this kind of report in HTMLDB?
Please guide me in this area.
Thanks
HA

The htmldb_collections API (apec_collections in 2.2) is a very useful method for rendering reports and one I have used extensivly in the past.
Once created and populated you can reference your collection as if it were a SQL table i.e.
Select c001, c002, c003
from htmldb_collections
where collection_name = 'MY_COLLECTION';
You can absolutly base an Apex Report region on collections. Just treat them as another table that you can select from, join to others etc.
In order to utilise this you must do the following:
1) Create your collection:
note that collections only persist for the duration of your session and you can only see the data you inserted into the collection. Also I would create this collection as the Database user who owns the Apex Workspace
htmldb_collection.create_or_truncate_collection ('MY_COLLECTION');
2) Populate your collection:
In your case I would set a loop construct that parses through your pl/sql table and assign all values as described below. I assumed that my_plsql_tab has 3 columns called Val1, Val2, Val3
FOR x IN 1..my_plsql_tab.count
LOOP
htmldb_collection.add_member (p_collection_name => 'MY_COLLECTION',
p_c001 => my_plsql_tab(x).val1,
p_c002 => my_plsql_tab(x).val2,
p_c003 => my_plsql_tab(x).val3
END LOOP;
Note that you can have upto 60 elements in your collection.
3) Access your collection:
Select c001, c002, c003
from htmldb_collections
where collection_name = 'MY_COLLECTION';
This quesry can then form the source of your sql report region.
Hope all that helps

How to select data from a PL/SQL table

Hi,
I am selecting data from database after doing some screening i want to store it in a PL/SQL table (temporary area) and pass it to oracle reports.
Is there any way to select the data from a PL/SQL table as a cursor. Or is there any other way of holding the temporary data and then pass it back as a cursor.
Regards
Kamal

A PL/SQL "table" is anything but a table. Whoever came up with this term in PL/SQL to describe what is known as dynamic arrays (the correct programming terminology that existed since the 70's if not earlier and what is used in all other programming languages I'm familiar with)... well, several descriptions come to mind and none of them are complimentary.
You cannot "select" from a PL/SQL dynamic array as it is not a table within the Oracle context of tables.
Thus you need to convert (cast) a PL/SQL dynamic array into a temporary Oracle data set/table in order to select from it. This is in general a Bad Idea (tm). Oracle tables and SQL and concurrency controls and all that are especially designed for processing data. PL/SQL arrays is a very simplistic data structure with very limited usage. Why would you want to use that in SQL via a SELECT statement when you can use Oracle tables (or proper temp tables) instead? Besides that, it is also slow to cast a dynamic PL/SQL array into an Oracle SQL data set structure (context switching, copying of memory, etc).
The proper way to use PL/SQL to generate data sets for use via the SQL engine is pipelined table functions.
This is not to say that you should never use PL/SQL arrays and casting in SQL.. simply that you need to make sure that this is the correct and scalable way to do it. And that will also always be an exception to the rule when you do.

Cast DBMS_SQL.NUMBER_TABLE to another pl/sql table-of-number type?
