Ive got loads of new entries that need to be entered into a table if they're not in there already.
Is there a quick way of doing this rather than having to add the entries manually using some kind of tool rather than using manual sql statements(would take a very long time since theres 800 new entries).?
I need to load (using SQL Loader) an huge XML file, with several hundreds of records into an Oracle Table.The XML file schema is pretty simple, and it's anything like this:
<dataroot>
<record>
<companyname>LimitSoft S.A.</companyname>
<address>Street Number 1</address>
[code]...
I'm trying to use the help included in this link [URL]...
When they refer to schema[URL].... what should I use?? I do not need to use the Oracle website to register anything, right?
I am having the following table and values.
A | B
=====
1 | 1
2 | 2
3 | 3
4 | 4

=========
1 | 1 |
2 | 2 | 3 --> 1+2
3 | 3 | 6 --> 3+3
4 | 4 | 10 --> 6+4
5 | 5 | 15 --> 10+5

In our 2-node RAC , Node1 was hung for a while. So, I wanted to restart that Instance. But I had some 50 services running in Instance 1(Preferred Instance) which has to relocated before I bounce the instance.
Question 1.
Instead of using srvctl relocate for each service, Is there any way to quickly relocate all services to the Node2 (Available Instance) ?
Question2.
When a service is relocated , are DMLs running from sessions using that service be 'moved' to the available instance ? Or, is it just the SELECTs that can be failed over ?
In the recent past we have been observing the DB connection from application to database using ODBC is taking long time. When I fire LSNRCTL SERVICE command, for our instance the ESTABLISHED = count is being shown a huge number like 45000 and even more some times.
When we restart the instance suing shutdown immediate or abort commands. The established connections count is becoming 0 and again getting increased slowly. Once the count is reduced the connections are getting established quickly without any issue.

5) After running this procedure, i shud see 5124 records, but i see zero records.
I am bit confused to display all the rows in a column using stored procedure like
In sqlserver:
create procedure test
as
begin
select * from table;
end
in sqlserver it is working perfectly.
In oracle:
create or replace procedure test
is
begin
select * from table;
end;
But in oracle i am getting an error like select * into something like that.I understand the error. i.e. i need to move the column values into variables.if it a single row then there will be no problem.i want to display all the rows in the table at one time.i can not use cursors.
