Oracle Equivalent to SQL Server Linked Servers

I'm trying to make that jump over to Oracle. One of the things I am doing is replicating everything I do in MS SQL 2005 to Oracle 10g. In Microsoft, I pull data from AS/400 through a linked server. I'm having trouble finding anything on the web on this, but I think I'm using the wrong terms. So I have two questions.
1. What do you called a linked server in the Oracle terminology?
2. Is it possible to link to AS/400 through Oracle and ISeries Access?
Thanks
Adam

For Oracle to Oracle links, look up 'database links'; for third party databases, look at 'Heteregenous services'.
There are two varieties of heteregenous services - 'transparent gateways' which are paid options and the basic version which essentially uses ODBC.

Oracle equivalent to SQL Server Table Variables ?

Does Oracle have anything equivalent to SQL Server table variables, that can be used in the JOIN clause of a select statement ?
What I want to do is execute a query to retrieve a two-column result, into some form of temporary storage (a collection ?), and then re-use that common data in many other queries inside a PL/SQL block. I could use temporary tables, but I'd like to avoid having to create new tables in the database, if possible. If I was doing this in SQL Server, I could use a table variable to do this, but is there anything similar in Oracle ? SQL Server example:
use Northwind
DECLARE @myVar TABLE(CustomerID nchar(5), CompanyName nvarchar(40))
INSERT INTO @myVar(CustomerID, CompanyName)
select CustomerID, CompanyName
from Customers
--Join the variable onto a table in the database
SELECT *
FROM @myVar mv join Customers
on mv.CompanyName = Customers.CompanyName
The closest I've found in Oracle is to use CREATE TYPE to create new types in the database, and use TABLE and CAST to convert the collection to a table, as shown below. I can't see anyway without creating new types in the database.
CREATE TYPE IDMap_obj AS Object(OldID number(15), NewID number(15));
CREATE TYPE IDMap_TAB IS TABLE OF IDMap_obj;
DECLARE
v_Count Number(10) := 0;
--Initialize empty collection
SourceIDMap IDMap_TAB := IDMap_TAB();
BEGIN
--Populate our SourceIDMap variable (dummy select statement for now).
FOR cur_row IN (select ID As OldID, ID + 10000000 As NewID From SomeTable) LOOP
SourceIDMap.extend;
SourceIDMap(SourceIDMap.Last) := IDMap_obj(cur_row.OldId, cur_row.NewId);
END LOOP;
--Print out contents of collection
FOR cur_row IN 1 .. SourceIDMap.Count LOOP
DBMS_OUTPUT.put_line(SourceIDMap(cur_row).OldId || ' ' || SourceIDMap(cur_row).NewId);
END LOOP;
--OK, can we now use our collection in a JOIN statement ?
SELECT COUNT(SM.NewID)
INTO v_Count
FROM SomeTable ST JOIN
TABLE(CAST(SourceIDMap As IDMap_TAB)) SM
ON ST.ID = SM.OldID;
DBMS_OUTPUT.put_line(' ' );
DBMS_OUTPUT.put_line('v_Count is ' || v_Count);
END;

Hi, got this from our plsql guys:
The term "table function" is a bit confusing here. In Oracle-speak, it means a function that can be used in the from list of a select statement thus:
select * from Table(My_Table_Function()),..
where...
The function's return type must be a collection that SQL understands. So for the interesting case -- mimicking a function with more than one column -- this would be a nested table of ADTs where both the ADT and the nested table are defined at schema level. PL/SQL -- by virtue of some clever footwork -- allows you to declare the type as a nested table of records where both these types are declared in a package spec. This alternative is generally preferred, especially because the nested table can be of Some_Table%rowtype (or Some_Cursor%rowtype if you prefer).
As I understand it from our man on the ANSI committee, our use terminology follows the standard.
The construct below seems to be a bit different (though there are similarities) because it appears from your code sample that it's usable only within procedural code. And the object from which you select is a variable rather than a function.
So, after that preamble... the answer would be:
No, we don't have any constructs to let you "declare" something that looks like a regular schema-level table as a PL/SQL variable -- and then use (static) SQL on it just as if it were a schema-level table.
But yes, you can use PL/SQL's pipelined table function to achieve much of the same effect.
Look at the attached Table_Function.sql.
It shows that you can populate a collection of records using ordinary PL/SQL code. You can't use SQL for insert, update, or delete on such a collection. I see that SQL Server lets you do
insert into Program_Variable_Table select... from Schema_Level_Table
The PL/SQL equivalent would be
select...
bulk collect into Program_Variable_Collection
from Schema_Level_Table
The attached shows that once you have populated your collection, then you can then query it with regular SQL -- both from inside PL/SQL code and from naked SQL.
and the code is here
CONNECT System/p
-- Drop and re-create "ordinary" user Usr
EXECUTE d.u
CONNECT Usr/p
create table Schema_Things(ID number, Description Varchar2(80))
create package Pkg is
subtype Thing_t is Schema_Things%rowtype;
type Things_t is table of Thing_t; -- index by pls_integer
Things Things_t;
-- PLS-00630: pipelined functions must have
-- a supported collection return type
-- for "type Things_t is table of Thing_t index by pls_integer".
function Computed_Things return Things_t pipelined;
procedure Insert_Schema_Things(No_Of_Rows in pls_integer);
end Pkg;
create package body Pkg is
function Computed_Things return Things_t pipelined is
Idx pls_integer;
Thing Thing_t;
begin
Idx := Things.First();
while Idx is not null loop
pipe row (Things(Idx));
Idx := Things.Next(Idx);
end loop;
end Computed_Things;
procedure Insert_Schema_Things(No_Of_Rows in pls_integer) is
begin
Things := Things_t();
Things.Extend(No_Of_Rows);
for j in 1..No_Of_Rows loop
Things(j).ID := j;
Things(j).Description := To_Char(j, '00009');
end loop;
insert into Schema_Things
select * from Table(Pkg.Computed_Things());
end Insert_Schema_Things;
end Pkg;
-- Test 1.
begin Pkg.Insert_Schema_Things(100); end;
select * from Schema_Things
-- Test 2.
begin
Pkg.Things := Pkg.Things_t();
Pkg.Things.Extend(20);
for j in 1..20 loop
Pkg.Things(j).ID := j;
Pkg.Things(j).Description := To_Char(j, '00009');

Oracle equivalent of sql server CLRSplitSting function

Hello Friends,
I have a query in SQL Server - which is getting data .
select addl_info_id, sort_seq, code, row_data, addl_info_group_id, group_sort_seq, group_row_data       from dbo.CLRSplitString('2406081,2410381,2427008,2430449,2466981,2495083,1586420,2406081,2410381,2427008,2430449,2466981,2495083,1586420','',',') x         join ein_addl_info_v v on x.col1 = v.addl_info_id       order by sort_seq
we have same data in oracle too so I converted the above sql server query to ORACLE Like this ..
select addl_info_id, sort_seq, code, row_data, addl_info_group_id, group_sort_seq, group_row_data from ( with t as (

join cnh_cs_targ_csce_eur_1.ein_addl_info_v v on x.sub_str= v.addl_info_id     order by sort_seq

Here your code:
WITH t AS
   SELECT '2406081,2410381,2427008,2430449,2466981,2495083,1586420,2406081,2410381,2427008,2430449,2466981,2495083,1586420' str
    FROM DUAL
SELECT REGEXP_SUBSTR (str, '[^,]+', 1, LEVEL) sub_str
   FROM t
CONNECT BY LEVEL <= REGEXP_COUNT (str, '[^,]+');The reason of the problem is that in your query the column str was having value , (comma). Your query:
select '2406081,2410381,2427008,2430449,2466981,2495083,1586420,2406081,2410381,2427008,2430449,2466981,2495083,1586420','',',' str from dual;was returning 3 columns.
I have also modified the condition in REGEXP_COUNT.

SQL Server linked servers screens SSMS

Where in SSMS can you get to the "linked server" screen for configuration details for existing linked servers, as opposed to setting up a new linked server, I want to check the security tab via the software GUI as opposed to running SQL. I cant
see where you can see them, I know from memory when setting up a new linked server there is a "general", "security" and "server options" tabs, so I assume you can see all of those for already created linked servers.

Check Server Objects --> Linked Servers in SSMS object explorer.

Oracle equivalent to SQL Server Profiler

Is there a tool within Oracle that can analyse SQL coming from an application similar to the Profiler tool within SQL Server.
I have looked at my available icons within the Oracle Enterprise Manager Console but I have not noticed anything I think would do the same job.

i want to query oracle database from sql server can anyone tell steps 2 followed
i tried with linked servers but it is throwing errors can anyone hepl in this regard
The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction.
OLE DB error trace [OLE/DB Provider 'MSDAORA' ITransactionJoin::JoinTransaction returned 0x8004d01b].

First of all - you are in the wrong forum.
Look either for the Database general or search for Transparant / Heterogenous Gateways.

"block change tracking" equivalent in sql server

Hi All,
If someone has expertise in both oracle and sql server, pls let me know if there is " block change tracking" equivalent in sql server. I know sql server has incremental/differential backup, curious to know whether it got this equivalent feature.

Create and insert into table from Oracle to MS SQL server.

Hello,
Oracle Database 11g and Red hat 5
I have a very different kind of issue. I am handling the ORACLE db(remote db with all the important data). On the other side their is a MS SQL server db(local db with some testing data in it). All the users will access the ORACLE db for the actual processing but for sometime they need to apply some of their own concepts. So they will transfer the data from ORACLE to MS sql server.
I want to create a code in ORACLE db like a procedure , which will create a table in MS sql server , insert data into it,Also create some metadata table to keep some of my table's info on MS SQL serve db,If the table is present it should append the data, .... like many things ...
Overall my question is , how can i write a code to make these operation on a remote db, that to these operations are DDL and on MS SQL Server(Non-Oracle) ???
Please guide me with some ideas or solutions ...
Also provide if you have some good links to study ...
thanks in advance.

I'm not sure why you never visit http://tahiti.oracle.com prior to asking any question. Is it forbidden in your locale? Are you afraid of it? Will your salary be decreased when you visit the documentation?
http://www.oracle.com/pls/db111/search?word=sql+server&partno=
should provide sufficient information.
Your doc question must be considered a violation of Forum Etiquette and an abuse of this forum.

Oracle 8i vs SQL Server 7 or 2000

Can anybody provide a link or information about what is the best choice to choosing Oracle 8i or SQL Server? I want a technical answer not based on market share or bias.
I have been an oracle DBA and developer for 5 years. Reading up on SQL Server,it seems very powerful as well as Very cost effective compared to Oracle 70% cheaper in some cases.
I am currently researching the back end and front end tools needed for a internal Application system:
20Gig Minimum sized database
80-100 Simultaneous Users
Database server on NT4.0/2000
Any information would be very helpful
Please email to [email protected]
and/or post info.
Thanks

To balance the equation a little bit:
well, here goes the technical difference between sql svr and oracle8i db server:
1. SQL Server has much more rich, intuitive development tools. I find the Oracle tools a bit antiquated and clunky.
2. "control file management is there in oracle. >> BUT NOT IN SQLSVR." Never had the need to "manage files" from the DB, so I'm not sure of the point here.
3. You can manage partitions in SQL Server.
4. Oracle is tied to Java whereas SQL Server is more VB friendly and has JScript support.
5. SQL Server built extensions to TSQL (like PL/SQL) to support direct return of XML in a very simple manner. I'm still swinning through
6. "Operating System authentication is there in oracle. BUT NOT IN SQLSVR." This is just plain wrong. You can authenticate at the OS or DB level in SQLServer.
7. SQL Server does replication including merge replication.
8. Building data warehouses, mining, datamart, MTS, DSS, OLTP is heavily supported in SQL Server.
9. SQL Server introduced the self-tuning database making the administration very simple.
10. SQL Server supports clustering, warmbackups, etc.
11. I can show you several ways to backup/restore and all are very fast.
12. SQLServer2000 has all of the development features of Oracle (and then some) for a fraction of the cost.
13. Oracle's high-end features are better and more complete, and it works on more platforms.
My choice as a developer in a Win2000/NT type environment is SQL Server hands down. Big companies with lots of data have a tougher choice. I think Oracle is more "big iron" and high-end admin friendly, and SQL Server is more developer, self-maintaining, and pocketbook friendly. I depends upon what's important to you.
ALL ABOVE INFORMATION IS BASED ON MY EXPERIENCE WITH SQL SERVER FROM 1996 TO PRESENT.

Oracle 10g to SQL Server 2012

Hi,
We are planning to upgrade our SAP. Our environment: Windows Server 2003, ERP ECC 6, Oracle 10g.
Am looking for guides to migrate our Oracle database to SQL Server 2012.
With new server, may I know how to convert our data from oracle to SQL Server 2012?
Thank you.

Hi,
First place to start
https://websmp207.sap-ag.de/OSDBMIGRATION
Then check PAM to ensure the direction and versions you want to migrated are supported https://websmp207.sap-ag.de/pam.
Please check link here.
http://scn.sap.com/docs/DOC-8324
In marketplace you can also use the guidefinder, for your versions this should be correct.

Cannot connect to Oracle database from SQL Server

Hi
We have set up a SQL Server linked server and tried to use this SQL Server linked server to connect to Oracle database. We are using SQL Server 2008 and Oracle client 11g 11.02.00.01. However, we got this error message:
Msg 7347, Level 16, State 1, Line 1
OLE DB provider 'OraOLEDB.Oracle' for linked server 'OurLinkedServer' returned data that does not match expected data length for column '[OraOLEDB.Oracle].Ourfieldname'. The (maximum) expected data length is 6, while the returned data length is 2.
We are able to connect some of the tables ok but some of the tables are not connected and got the above error message.
Any suggestions are greatly appreciated.
Thanks a lot
Tom

Hi
Here is more information. We just found out that the Oracle database team changed the character set to something else and then they changed it back to UTF8.
Currently, it is using UTF8 character set on the Oracle side. Will this causing us this error message on our sql server linked server?
The error message said "The (maximum) expected data length is 6, while the returned data length is 2."
This refers to a field/column with char(1)
Any suggestions are greatly appreciated
Thank you
Tom
