Query LPAR in oracle database.

Hi Folks
I was assigned to query LPAR and user_id in some databases. Based on the info on excel sheet, we are going to match up LPARs with physicals servers, and I’ll then determine how many unique database ids exist across each physical server.
I knew how to query user_id`s, but how do I query LPAR info along with user_id`s and putting it in excel sheet?

whats your database and version? define lpar and user_id? an os user? a database schema owner? how many instances have you got? define unique database ids?

How to pass a date parameter from report builder query designer to oracle database

i'm using report builder 3.0 connected to oracle database. i'm trying to pass a date parameter in the query with no success, i don't
know the exact syntax. I've tried :
SELECT * FROM igeneral.GCL_CLAIMS where CREATED_BY IN (:CREATED_BY) AND CLAIM_YEAR IN(:UW_YEAR) AND (LOSS_DATE) >To_Date('01/01/2014','mm/dd/yyyy')
it worked perfectly.
However if i try to put a date parameter "From" instead of 01/01/2014 it will not work, a Define Query Parameter popup window appear and error occurred after i fill
the values (usually i shouldnt get this popup i should enter the value when i run the report)
SELECT * FROM igeneral.GCL_CLAIMS where CREATED_BY IN (:CREATED_BY) AND CLAIM_YEAR IN(:UW_YEAR) AND (LOSS_DATE) >To_Date(:From,'mm/dd/yyyy')
appreciate your assistance

Hi Gorgo,
According to your description, you have problem when in passing a parameter for running a Oracle Query. Right?
Based on my knowledge, it use "&" as synax for parameter in Oracle, like we use "@" in SQL Server. In this scenario, maybe you can try '01/01/2014' when inputing in "From". We are not sure if there's any limitation for To_Date()
function. For your self-testing, you can try the query in sqlplus/sql delveloper. Since your issue is related to Oracle query, we suggest you post this thread onto Oracle forum.

Query in timesten taking more time than query in oracle database

Hi,
Can anyone please explain me why query in timesten taking more time
than query in oracle database.
I am mentioning in detail what are my settings and what have I done
step by step.........
1.This is the table I created in Oracle datababase
(Oracle Database 10g Enterprise Edition Release 10.2.0.1.0)...
CREATE TABLE student (
id NUMBER(9) primary keY ,
first_name VARCHAR2(10),
last_name VARCHAR2(10)
2.THIS IS THE ANONYMOUS BLOCK I USE TO
POPULATE THE STUDENT TABLE(TOTAL 2599999 ROWS)...
declare
firstname varchar2(12);
lastname varchar2(12);
catt number(9);
begin
for cntr in 1..2599999 loop
firstname:=(cntr+8)||'f';
lastname:=(cntr+2)||'l';
if cntr like '%9999' then
dbms_output.put_line(cntr);
end if;
insert into student values(cntr,firstname, lastname);
end loop;
end;

Store SQL Query in Oracle database

Hello,
I am storing SQL query in database. here is an example of query.
INSERT INTO TABLE_1 Values (' " + getValue1() + " ', ' " + getValue2() + " ' )
getValue1() and getValue2() are functions to retrieve values.
When I read query from the database and execute it, it doesn't read values from function.
After I read query from database I would expect it to be
INSERT INTO TABLE_1 Values ('value1', ' value2' ) but it is not reading values and trying to execute whatever I got from database.
Any help?
Thanks

Thanks for your reply. Let me give you more info.
All I am trying to do is storing queries in oracle
database to use it in future for reporting. As I am
doing reporting where clause will be different every
time. Reporting involves queries not updates. But in any case that means that you would use a java SQL string that is useable via a prepared statement. As such your statement would look like....
INSERT INTO TABLE_1 Values (?,?)
Is it not possible to substitute variable string I
got from database?What do you mean?
SQL is SQL. You construct SQL so it is valid and runs. Can you construct SQL so it runs a function/select and uses that value in some more SQL - depends on the database, but usually.
But that has nothing to do with java - it is SQL.
Query contains variables that I have in Java code .Then it is SQL. It is java. You use bind variables (see PreparedStatement) and assign values to it.
The SQL for such a query would look like the following...
select field1, field2 from table1 where id=?
In your java you would then use something like PreparedStatement.setInt(1, 100), to fill in the value for the '?' in the above.
You might also note that your solution will not work for any arbritrary SQL statement unless you are also storing meta data about the SQL itself. For instance the following SQL statements would return the same result set but your java code would have to populate the bind variables different for both...
select field1, field2 from table1 where id=? and name=?
select field1, field2 from table1 where name=? and id=?

Querying an Oracle Database Using XSL

I know from years of experience as an Oracle DBA that to suggest that a program generate SQL is anathema, but I'm going to ask anyway!
Is there currently (or soon) to be a means of submitting XSL (or, perhaps, some variant based on the most recently published "standard") to an Oracle database and receiving an XML result set?
Note that I have not mentioned writing any SQL myself. I'm either looking for some middleware to translate the XSL "query" into the appropriate SQL query (with appropriate after-query transformations) or for the database engine itself to be able to parse and optimize XSL.
I just read a position paper (dated 1998) on this site that says that Oracle intends to closely follow developments in the world of XML Query. And, I've read in a "Byte" article ("Where Are The XML Apps We Can See And Touch? Report From XML DevCon 2001", April 2001, Jon Udell) that Steve Muench had demonstrated some means of super-imposing an XML schema over top of a database in order to query it via XPath. Where does the product stand in regards to this type of functionality?
Thanks in advance,
David Park

http://technet.oracle.com/tech/xml/xdk_java
- The XSU can transform data retreived from object-relational database tables or views into XML.
- The XSU can extract data from a XML document and using a canonical mapping, insert the data into the appropriate columns/attributes of a table or a view.
- The XSU can extract data from a XML document and apply this data to updating or deleteing values of the appropriate columns/attributes.

Problem querying an Oracle Database using PHP

Hi there, im rather new to Oracle so pardon my ignorance if this is completely obvious but I am creating a web form that queries an oracle database, firstly is a user form which looks like this.
 
Search for Investments 
<form action="query.php" method="POST"> 
<input type = "text" name = "invest"> 
<input type="submit" value="Search" name="submit" /> 
</form> 
----------------------- 
and the php script which looks like this 
----------------------- 
<?php <
print "<HTML><PRE>"; 
require_once('connect.php'); 
select_data($conn); 
$invest = $_POST['invest']; 
echo "Returning results related to $invest"; 
function select_data($conn) 
{ $stmt = ociparse($conn,"select * from investmentbase where INVTYPE='$invest'"); 
ociexecute($stmt,OCI_DEFAULT); 
echo "<table border = 1 class=results>"; 
echo "<tr>"; 
echo "<td>Reference Number</td>"; 
echo "<td>User ID</td>"; 
echo "<td>Investment Type</td>"; 
echo "<td>Investment Description</td>"; 
echo "<td>Amount Required</td>"; 
echo "<td>Due Date<td>"; 
echo "</tr>"; 
while (ocifetch($stmt)){ 
echo "<tr>"; 
echo "<td>"; 
echo ociresult($stmt,"INVREF")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"USERID")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"INVTYPE")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"INVDESCRIPTION")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"AMOUNTREQUIRED")." "; 
echo "</td>"; 
echo "<td>"; 
echo ociresult($stmt,"REQUIREDATE"); 
echo "</td>"; 
echo "</tr>"; 
} 
echo "</table>"; 
} 
ocilogoff($conn); 
print "</PRE></HTML>"; 
?> 
When i search for a value that is in the database no results are returned, however the form is definitely posting the variable as the echo statement on the PHP script displays it. Any ideas would be gratefully appreciated
Many Thanks
Paul

Do you need to set $invest before calling do_select() and pass it as a
parameter? Also, watch out for SQL Injection security risks. Try
using a bind variable.
$invest = $_POST['invest'];
echo "Returning results related to $invest";
select_data($conn, $invest);
function select_data($conn, $invest)
$stmt = ociparse($conn,"select * from investmentbase where INVTYPE=:ibv");
ocibindbyname($stmt, ':ibv', $invest);
ociexecute($stmt,OCI_DEFAULT);
. . .Although the PHP 4 naming style for oci8 functions can be used with
PHP 5, I know there is a possibility you are using the PHP 4 OCI8
extension. If you are, then upgrade at least OCI8. There are some
notes on this in

1 TABLE ACCESS FULL TABLE PRISM.PRT_SALES_DISC_MATRIX Cost: 89,113 Bytes: 144 Cardinality: 1

Apart from the important syntactical error which sb has highlighted, the parallel hint does not mandate that the statement is run in parallel.

Query using link server to an Oracle database failswhile similar query works

I have two queries almost the same that use a link to an Oracle database. One works ok, the other is a copy of the first with a few fields selects removed. The first one works fine, the copy fails with: Cannot get the data of the row from the OLE DB
provider "OraOLEDB.Oracle" for linked server "linkname".
They are so similar, why would one work but not the other?
First query, this one works:

Thanks very much for any help with this.

* Consider putting parentheses around the 3 oracle tables so the 3 of them can possibly be treated as a unit. Assuming there's some performance impact due to the linked server, this MIGHT help, may do a little joining over on the Oracle side of
the world. In either case, it's a little cleaner. They syntax below, including a few extra line breaks for clarity, should be correct. (try the change to the ON clause suggested above too, though).
The parentheses will not help much. SQL Server will remote (as the term is) the query to the Oracle instance if this appears to have a lower cost and there is nothing the blocks remoting.
On the other hand, OPENQUERY can be an alternative to ensure that this happens:
left outer join
OPENQUERY (linknametooracledb,
 'SELECT ...
FROM "M01Tab01_Main" mn
JOIN "M01Tab06_Ord" mt ON mn."Master_Recid_1" = mt."Master_Recid_1"
JOIN "M01Tab09_Dx" mdx on mn."Master_Recid_1" = mdx."Master_Recid_1"') mn on td.visitnumber = mn."Pt_Acct_5"
But this presumes that you there are no columns from the SQL Server side that are used to select data from the Oracle side. That is, the above could lead to far much data being brought across the wire.
Then again, this does not really seem to relate to the original problem where a stored procedure was not working at all. That problem is not very easy to assist with since code post is the not the authentic code as pointed out in the thread. For instance
inner JOIN linknametooracledb."M01Tab06_Ord"
Has nothing to do with Oracle, but accesses a table in the schema linknametooracledb.
I think to help dmcm, you need a really good crystal ball - at least as long he/she does not share the actual code.

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.

How can i query oracle database data to xml file with c++?

I want query data to xml file directly in my c++ application .
I know the oracle XSU provide interferce for query data to xml
file directly.
But XSU for oracle8i does not support c++.
I do not know if XSU for oracle9i support c++.
can you tell me?
If i do not use XSU to finish my applicayion.
what interface that oracle provide can help me do my work?
thank you !

BTW why do you want to migrate oracle database data to db2 database? Any specific project requirement like Parallel run with Oracle database (e.g data replication)? Or any other issues - Cost? Manageability? Availability? Business requirements?
Do you need to do a day-to-day data transfer or it is for permanent migration?

Query Oracle database using JCheckBox getLabel()

Hey guys.
I'm not sure if this is the right place, so if it's not I greatly apologise! I just figured if it include Java code then it's appropriate.
Anyway, just a query...
I've got a Java application hooked up to an Oracle database. I was just wondering if it's possible to query a table in my database by using the getLabel() of JCheckBox?
E.g., SELECT * FROM Login WHERE Name LIKE '%box.getLabel()%'
I know getLabel() is deprecated now.
Now I look at it it seems more like an Oracle question than Java. :s
I was just wondering if this is possible at all? Don't want the code or any hints/help, just to see if it is do-able. :)
Thanks in advance!

Thanks for your feedback. :) That's a relief, as I didn't want to be clutching at straws if something couldn't be done.
Thanks buddy.

Executing the SQL query across 2 different databases of Oracle

Hello All,
In Microsoft SQL server we can execute following type of SQL query across 2 different databases:
select * from TEST1.dbo.GENERIC_TABLE1 union select * from TEST2.dbo.GENERIC_TABLE2;
Here TEST1 and TEST2 are 2 different databases.
Can we do the same in Oracle?

yes you can, but first one has to setup a database link
Look up CREATE DATABASE LINK and then take things from there!
