Call procedure with MS SQL from linked Oracle server

I have a procedure on a remote server that I can call from SQL*PLUS
set serveroutput on
declare rez varchar2(99); msg varchar2(99); begin radar.test('AL25',rez,msg); dbms_output.put_line('Rez='||rez);
dbms_output.put_line('Msg='||msg);
end;
it gives me the neccessary result.
But I need to call the same procedure with MS SQL from a linked Oracle server, I'm trying to do it through openquery for a while, but no success yet.
Can someone tell me what is the right syntax for that query in OPENQUERY?

Have you tried configuring Oracle Heterogenous Services/ Transparent Gateway? This would let you link Oracle to SQL Server via a database link which should solve your problem.

Hi,
I have a PL/SQL table of tables sructure on which I want to use extend option available with PL/SQL tables.
But I am not able to do so. Could anyone help?
Below is sample code given.

Writing to a temp table in a stored procedure with dynamic sql

Hi
I am writing into a temp table with dynamic sql:
select coloum_name into #temp_table from
+
@DestinationDBName+'.information_schema.tables
and then I am trying to use #temp_table in the procedure:
select coloum_name into #anotherTable from #temp_table
but I am getting an error that #temp_table is not recognized.
Can a temp table not be used in dynamic sql ?
How can I overcome this problem ?

Temp Table Can used easily in Dynamic Query in SQL Server and here is small Exmaple you can check it and do like it
CREATE PROC test
AS
BEGIN
CREATE TABLE #T1
(ID int , NAME Nvarchar(50))
CREATE TABLE #T2
(ID int , NAME Nvarchar(50))
DECLARE @SQL NVARCHAR(MAX)='Insert into #T1
SELECT database_id , Name FROM Sys.Databases
Insert into #T2 Select ID , Name from #T1 '
EXEC SP_ExecuteSQL @SQL
SELECT * FROM #T2
DROP TABLE #T1
DROP TABLE #T2
END
Exec Test

Can anyone help me in a problem with PL/SQL Tables & the Java getArray()

The problem is the following:
I would tike to get a PL/SQL Table (a table of varchar2) into a Java String Array.
It works very well except that instead of getting the characters in the PL/SQL Table
I receive the character codes in each string.
In the following example i should get:
spring
summer
outumn
winter
Instead I get:
0x737072696E67
0x73756D6D6572
0x6F7574756D6E
0x77696E746572
Steps to try the sample
1)Creating the following type
create or replace TYPE CHAR_ARRAY IS TABLE OF VARCHAR(32767);
2)Creating the following stored procedure
create or replace PROCEDURE MQ_MSG_PROCESSOR
   MessageText in VARCHAR2,
   QueueName out VARCHAR2,
   RplyMessage out CHAR_ARRAY,
   HastoCommit out NUMBER

      conn.close();

Hi,
I tried the code with same procedure.
That works out fine for me..
and it prints out exactly the same words as you mentioned..:))
may be you must have changed something later on.. which started printing character codes..
but for me it works perfectly fine..
All The Best..

Problem with pl/sql table data type

hai friends,
i have one procedure it has some in parameters and one out parameter which fetches values to front end.
But the out parameter will be pl/sql table data type.
if it is ref cursor
then i declared as
var x refcursor;
exec procedure_name(1,:x);
it is ok.
but for pl/sql table data type is out parameter then what i will do in the prompt .
give me syntax and clarify my doubt.
advanced thanks...
madhava

The SQL*Plus VARIABLE statement does not support user-defined types, hence it cannot support nested tables. It can support cursors because they can be weakly typed (so we can use the one SQL*Plus VAR to hold any shape of resultset). Nested tables are strongly typed; SQL*Plus is a relatively stupid interface and cannot be expected to understand UDT.
So, it you want to use nested tables as output you'll need to code a wrapping procedure that can understand your nested table type and handle it accordingly.
Sorry.
Cheers, APC

Need help with pl/sql tables

i am trying but iam not understanding this....
Evaluate this program fragment:
DECLARE
TYPE user_tab_rec IS RECORD (
db_user dba_users.username%TYPE,
DBA_TAB dba_tables%ROWTYPE);
TYPE user_rec_tab IS TABLE OF test_rec
INDEX BY BINARY_INTEGER;
Tab_rec dba_tables%ROWTYPE;
Obj_owner dba_objects.owner%TYPE;
begin
(processing)
end;
What line will generate an error?
1.
TYPE user_tab_rec IS RECORD (
2.
db_user dba_users.username%TYPE,
3.
DBA_TAB dba_tables%ROWTYPE);
4.
TYPE user_rec_tab IS TABLE OF test_rec
5.
INDEX BY BINARY_INTEGER;
6.
Tab_rec dba_tables%ROWTYPE;
7.
Obj_owner dba_objects.owner%TYPE;
The correct answer is b. The line in b attempts to define a PL/SQL TABLE TYPE using a record that contains a composite datatype, which is not allowed. Answers a, c, and d are incorrect because they will not generate any errors when compiled.
how can line b attempt to define a pl/sql table type..........
thank u ramsy

The correct answer is bB? I see no B.
Do you mean three?
But then again
maybe line ten.
Because (processing) isn't
valid syntax you see.
I know, I know
Let's see what'll go.
And then we'll see
Is it A B or C?

Can I call stored procedure with PL/SQL?

Oracle newbie question, it is.
Assume a very simple stored procedure like this:
Create or replace procedure aa (
inPar IN number, outPar OUT number)
IS
rrr Number;
Begin
Blah, blah, blah...
rrr := inPar + 100;
Blah, blah, blah...
outPar := rrr;
End;
So the questions are
1) How do I call the above stored proc and pass input parameter values dynamically?
2) How can I retreieve the results of outPar?
I did some research and I learn I can use a programming interface such as Visual Basic or Java. Is that the only way available? I know a small bit about SQL*Plus. f I've tried to enter some PL/SQL commands under SQL*PLUS but I'm stuck. I must have missed something..please.
In MS SQL Server environment I know what I can do. If I want to do the same thing, I just:
Create proc aa ( @inParam int, @outParam int OUTPUT )
as
blah, blah, blah
Set @outParam = @inParam + 1000
return 1
GO
Enter the following statements (via query analyzer) to call the SQL Server Stored procedure and get the result:
Declare @outX int
Declare @returnX int
exec @returnX = aa 100, @outX OUTPUT
print str(@outX)
print str(@returnX)
Go

maybe this example might be of some help:

Problem with a procedure with a type table varchar2

Hey,
I can't seem to call my function with a custom type:
The function:
FUNCTION f_get_urls(v_table IN t_table)
RETURN VARCHAR2
IS
v_urls VARCHAR2(600);
BEGIN
FOR i IN 1..v_table.count LOOP
v_urls := CONCAT(v_urls,v_table(i));
END LOOP;
RETURN v_urls;
END f_get_urls;
t_table is declared in the package header:
TYPE t_table is table of VARCHAR2(100) index by binary_integer;
All goes well if i call the fucntion from within the package, but when i call it from an other package I get the next error:
Error(12,11): PLS-00306: wrong number or types of arguments in call to 'F_GET_URLS'
This is the procedure where i'm caling the fucntion:
PROCEDURE temp1
IS

v_tab t_table;
v_temp VARCHAR2(100);
BEGIN
v_tab(1):='test';
v_tab(2):='test2';
v_temp:=pkg_print.f_get_urls(v_tab);
dbms_output.PUT_LINE(v_temp);

Any idea if i made an error or is this just not possible?
Thanks

SSRS - Stored procedure with Dynamic SQL Query

Am calling stored procedure in SSRS report. I have used Dynamic SQL query in stored procedure as I don't know the column name and column count. And I have used like below at end of the stored procedure "select * from ##temptable".
As I have used dynamic column, am not able to create report with this stored procedure. Can someone help me out to resolve this issue.
It will be highly appreciated if I get help.
Thanks

I have tried everything. But nothing has worked out.
If I get solution for below issue, it would be highly appreciated.
"An error occurred during local report processing.
The definition of the repport 'Main Report' is invalid.
The report defintion is not valid. Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition' which cannot be upgraded.

Hello,
I would suggest you post the complete error message to us for further investigation, if you preview the report before you deploy you may get a more detailed error that will help diagnose the source of the problem.
This issue is more related to SQL Server Reporting Services, it's more appropriate to discuss it in the forum below:

According to the documentation:
ORA-01555: snapshot too old: rollback segment number string with name "string" too small
Cause: Rollback records needed by a reader for consistent read are overwritten by other writers.
Action: If in Automatic Undo Management mode, increase the setting of UNDO_RETENTION. Otherwise, use larger rollback segments.
Error: ORA-01555: snapshot too old (rollback segment too small)
Cause: This error can be caused by one of the problems, as described below.
Action: The options to resolve this Oracle error are:
This error can be the result of there being insufficient rollback segments.
A query may not be able to create the snapshot because the rollback data is not available. This can happen when there are many transactions that are modifying data, and performing commits and rollbacks. Rollback data is overwritten when the rollback segments are too small for the size and number of changes that are being performed.
To correct this problem, make more larger rollback segments available. Your rollback data for completed transactions will be kept longer.
This error can be the result of programs not closing cursors after repeated FETCH and UPDATE statements.
To correct this problem, make sure that you are closing cursors when you no longer require them.
This error can occur if a FETCH is executed after a COMMIT is issued.
The number of rollback records created since the last CLOSE of your cursor will fill the rollback segments and you will begin overwriting earlier records.

I am new to SQL Developer (Version 3.0.02).
Our QC division wants to test stored procedures using SQL Developer.
I tried to test procedures with PL/SQL tables and SYS_REFCURSORS as input and output parameters.
When we run it by pressing the green arrow we get the Run PL/SQL window.
How can we:
- Put values to SYS_REFCURSOR and PL/SQL table type input parameters?
- How can we display SYS_REFCURSOR and PL/SQL table type output parameters?
All this time we were using SQL*Navigator. In Navigator the PL Tables and SYS_REFCURSORs outputs are shown in a nice grid.
Here, in SQL Developer, do we have to WRITE our own code to input and display these types of parameters????

Hi Channa,
Yes in SQL Developer 3.0 you will have to write your own code to test out ref cursors.
I had created test harness scripts for all my procedures having ref cursors as parameters.
And I had to dbms_output all the values on the screen.
Probably a limitation of the SQL Developer 3.0 tool.
In case you come across different solution to this do let me know also.
Thanks,
Viju

How to invoke PL/SQL Table parameter in the query string?

Hello,
I've met a problem invoking PL/SQL Table parameter in the query string, in OWS 3.0.
What I'm going to do is, to invoke a stored procedure to generate a web page using PL/SQL Web Toolkit 2.0, like: "http://.../owa/test_proc".
But there is a IN parameter for this procedure, and it's a PL/SQL Table variable. So I can't invoke the procedure sucessfully just using "http://.../owa/test_proc?v_plsql=i_plsql".
Did someone have met this kind of problem or have the answer to it? Thanks so much for your help.

When using procedures with pl/sql-tables as parameter they should be overloaded, e.g.:
procedure my_procedure (my_var in varchar2)...
and
procedure my_procedure (my_var in owa_util.ident_arr)
the procedure then can be called with:
http://..../my_procedure?my_var=Scott, which invokes the version with the varchar2 parameter, or
http://..../my_procedure?my_var=Scott&my_var=Miller......
which invokes the version with the pl/sql-Table
Another solution might be the use of flexible parameters, passing pairs of parameter_name, parameter_value to your procedure. Your procedure looks like:
procedure my_procedure (name_array IN owa.vc_arr, value_array IN owa.vc_arr)..
and is invoked (note the ! )
http://..../!my_procedure?ename=Scott&sal=200&job=clerk.....
looping through the pl/sql tables will retrieve values of ename, sal and job for name_array and Scott, 200 and clerk for value_array

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.

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).

PL/SQL TABLE AS OUT ON PROCEDURE CALL AND JDBCTHIN(NEED HELP

How can I pass pl/sql record in and out
and pl/sql tables in out thru a pl/sql procedure using jdbc with
the zip file of 816classes12.zip...
I have tried everything I know...
I know the procedure is working, others are using it with in
Oracle...
I need to use the information it generates.
here is what I have so far...
try
Class.forName ("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
oracle.jdbc.driver.OracleConnection conn =
(oracle.jdbc.driver.OracleConnection)
DriverManager.getConnection ("jdbc:oracle:thin:@--","NA","NA");
// SQL92 SyntaxCallableStatement
oracle.jdbc.driver.OracleCallableStatement cstmt =
(oracle.jdbc.driver.OracleCallableStatement)conn.prepareCall
("{call cbmd_proposal_PKG.DefaultTerms (?,?,?,?)}" ) ;
cstmt.setString(1,"5118");
cstmt.setString(2,"3");
cstmt.registerOutParameter
(2,oracle.jdbc.driver.OracleTypes.NUMBER);
cstmt.registerOutParameter
(1,oracle.jdbc.driver.OracleTypes.ARRAY,"");
cstmt.execute();
catch(Exception e)
System.err.println(e.toString());
e.printStackTrace();
null

The "X" in the second registerOutParameter is the type name which
you have created in oracle DB.
eg. if you have created a nested table
create Type integer_table is table of number(10);
then "X" = "INTEGER_TABLE" and it has to be in caps
and other thing to keep in mind is that it only works with nested
table or varray and not with pl/sql table.
