Hi all,
Please let me know the details of the following.
1.What is Multi-Threading?
2. How it is useful to increase the Performance of a SQL query.( How it is useful
in Optimizing the query.
3. How we'll use MultiThread concept in Partitions and Using Processors.( For Eg.. If I want to use MAX threads=14 and 16 processors in this situation how we use PArtition concept and how it will improve the bufffer size of the CPU)
Thanks in advance
HiCan an application populate two Grids from the database,simultaneously without using the multithreading using ADO.NETThanks in advanceMR_FBIJoin Bytes!

Can anybody help in introducing the YTD Concept:
My Table[ Monthly_Highlights_tb ] schema should contain like below:
[Month] [Base_Amount] [YTD]
APR-07 1000.00 1500.00
APR-07 500.00 1500.00
MAY-07 2000.00 3500.00
jUN-07 5000.00 8500.00
WHEN I run the below query:
UPDATE t
SET t.ytd = (SELECT SUM(q.base_amount) FROM Monthly_Highlights_tb q WHERE q.[month] = t.[month] AND q.[month] <= t.[month])
FROM Monthly_Highlights_tb t
output is coming as:
[Month] [Base_Amount] [YTD]
APR-07 1000.00 1500.00
APR-07 500.00 1500.00
MAY-07 2000.00 2000.00
jUN-07 5000.00 5000.00
cAN anybody correct the query?

What is the equivalent for Oracle's nested table concept in SQL Server ?
Is there anything like TABLE( ) function to select from nested table as in Oracle ?
Eg in Oracle :
SELECT t.* FROM TABLE(nested_table_datatype) t;
( like the above query used in Oracle PL/SQL and 'nested_table_datatype' is a table datatype created in Oracle using 'create type ...' syntax )
Please give the equivalent for above...
Thanks,
Sam

Hi
I am involved in a product development and want to understand the current best practices from the conception to product rollout. I have few questions. Appreciate your help and suggestions
Our project in a nutshell: Our team has developed the apps. using GUI-Oracle Forms & DBMS-Oracle 8i/9i with weblogic, Corba, windows 2000 server environment. It’s meant for 1000s of users with million of data. We are trying to integrate additional services/capability - messaging (wireless, chat etc.). As per the initial plan we have a central database and users will be using a local footprint database. The deltas (the changes) will be synchronized with the central database at a frequency say daily or nightly... We are concerned that having the database at the users desktop could leave the door wide-open for others to take a look at our code/design...
Questions:
1. UML case tools-- What’s the best tool available in the market as we want to revisit the design phase and identify the things that have been missed out in the prototype-(which was developed by a third-party)?
So far we have used ERWIN to extract the data model...
2. How can we eliminate the need to have a local footprint database at the users desktop.?. Since there is a lots of data, retrieving the data via internet could be very slow for users? (hope this is the case!) That’s what led our team to think of having a local database at the users desktop. Someone suggested to use the data files or caching the data.. Appreciate if anyone shed some light on this.. Is there a better way to do it?
3. Client connectivity: What are the softwares needed at the users PC. Since we use Oracle Forms to develop the application, do we need to install the oracle clients at the users PCs? how to establish the connectivity from the Users PC to our server and to the database. IF we have to use the oracle client, does that require licenses for every User? What do we need to consider from the network connectivity stand point.
4. Application Rollout: how to package our finished product - application exe that is installable across wide array of environment. (we thought of install shield). how do we test it for accuracy etc.,
5. Database optimization: In addition to DBA help, is there any product or proceedures to ensure dataModel optimization, SQL query performance etc.,
Appreciate you sharing your valuable thoughts on this with us..
I tried samples of FileTable in SQL Server 2012 to store files in database. I have following questions.
1. When I right click on FileTable, and say Explore File Table Directory, I was taken to a directory. But if I search the same directory in my server/machine, the directory is not available.
2. Can I use some external server/disk as a directory for FileTable?
3. How easy is to use FileTables using .Net web applications?
In SQL Server 2000, when i install a client connection only, it also install the enterprise manager, just by adding/register new SQL server. there you can access all the tables. but in SQL Server 2005 how can I achieve that? Coz when i only install the client tool for SQL Server 2005 it only enables to connect to database, not accessing it freely and sql server management studio not included.
please help..
I have an issue using parameterised reports connecting to Oracle using "ODBC" and "Microsoft OLE DB Provider for Oracle" using parameteried reports. The following error is generated "ORA-01008 not all variables bound (Microsoft OLE DB Provider for Oracle)" and a similiar one for ODBC. It works fine for simple reports. Do these 2 drivers have issues passing parameters for a remote Oracle query?
Thanks.
Hi!
I'm loading from Oracle using the OraOLEDB.Oracle.1 provider since I need unicode support and I get the following error:
TITLE: Microsoft Visual Studio
------------------------------
Error at myTask [DTS.Pipeline]: The "output column "myColumn" (9134)" has a precision that is not valid. The precision must be between 1 and 38.
------------------------------
ADDITIONAL INFORMATION:

------------------------------
BUTTONS:

------------------------------
For most of my queries to Oracle I can cast the columns to get rid of the error (CAST x AS DECIMAL(10) etc), but this does not work for:
1) Union
I have a select like "SELECT NVL(myColumn, 0) .... FROM myTable UNION SELECT 0 AS myColumn, .... FROM DUAL"
Even if I cast the columns in both selects (SELECT CAST(NVL(myColumn, 0) AS DECIMAL(10, 0) .... UNION SELECT CAST(0 AS DECIMAL(10, 0)) AS myColumn, .... FROM DUAL) I still get the error above.
2) SQL command from variable
The select basically looks like this:
"SELECT Column1, Column2, ... FROM myTable WHERE Updated BETWEEN User::LastLoad AND User::CurrentLoad"
Again, even if I cast all columns (like in the union), I still get the same error.
Any help would be greatly appreciated. Thanks!

Hello,
On my dev server I have working ssis packages that use connections Microsoft OLEDB provider for Oracle MSDAORA.1 and Oracle provider for oledb and OracleClient data provider.
I use one or the other according to my needs.
In anticipation and to prepare for the build of a new production server, I have build a test server from scratch and deployed to it the entire dev.
Almost everything works except Microsoft OLEDB provider for Oracle.
ssis packages on the test machine will return an error
Error at Pull Calendar from One [OLE DB Source [1]]: The AcquireConnection method call to the connection manager "one.oledb" failed with error code 0xC0202009.
Error at Pull Calendar from One [DTS.Pipeline]: component "OLE DB Source" (1) failed validation and returned error code 0xC020801C.
[Connection manager "one.oledb"]: An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80004005 Description: "Oracle error occurred, but error message could not be retrieved from Oracle.".
I have used the same installers for OS, SQL and Oracle SQL*Net on both dev and test machines. The install and then the restore/deployment on Test went fine.
Does anyone could point me to the right direction to solve this issue?
Thanks,

Hi Everyone,
I've been searching for a solution for this for a week-ish, so I thought I would post my quesiton directly. Here is my scenario..
Source: MS SQL Server
Destination: Oracle 10g
The destination table has a partition set on a column called "DATE_HIGH". How do I populate this date high column in my package? Currently I just have a source object, and a destination object, but I'm unclear how to populate this field in the destination. I've read one blog that states "use OLE DB Command" - but that isn't enough information for me to implement - Can someone be more specific in these steps? Here is an example of what my newb-ness needs to understand
OLE DB Source (Select * from Table) ---> OLE DB Command (What query goes here?) --> OLE DB Destination.
Second part of my question: There is a second column called "ROW_NUM" and there is an Oracle Sequence provided to me... What objects do I need (Source, Destination, OLE DB Command etc...) and how do I call this sequence to populate on the fly as I'm loading data from my source?
If these are simple questions - my appologies, I am new to the product.
Best Regards,
Steve Collins
Hi everybody,
I have designed a DTS package which will migrate a view from Sqlserver 2000 to Oracle.My package is using Microsoft OLEDB provider for Oracle driver for connecting to oracle.Im able to execute this package on the my system ie on the system where sqlclient is installed(Oracle client is also installed on my machine) .But when im doing it on the server im not able to do it.The Connection to Oracle Fails.
I wanted to know in order to connect to Oracle from the server,is it necessary that Oracle has to be installed on the server?.If yes, is it enough if i install oracle client on the server or Oracle Server version has to be installed on Server.
Please suggest me wht should i do know?
Thanks in advance

I have the OraOLEDB.Oracle provider installed to the (C:oraclexe) directory.
I am having problems querying from linked oracle server. When i setup oracle as a linked server and purposely enter an incorrect password the query i run tells me i have an incorrect password. So it at least knows that. when i set the correct password and run a query I get this error:
(i replaced the real server name with "someServer".)
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer" reported an error. The provider did not give any information about the error.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer".
This is how I set up my Linked server:
Provider: "Oracle Provider for OLE DB"
Product Name: SomeServer
Data Source: SomeServer
Provider String: "Provider=OraOLEDB.Oracle;Data Source=SomeServer;User Id=MyLogin;Password=MyPassword"
The query I run is:
Select * from [Someserver].[schema or database]..[tbl_name]
Any help??? What am i missing?
Oracle and MS drivers do not support parameterized queries, so update table set column=? where primarykey=? does not work for Oracle.
Anyone knows how to update an Oracle table through SSIS?

My application which ran perfectly well yesterday suddenly stopped working in this morning with following error message. I didn't change anything, at least I believe. Interesting thing is that I don't use any Oracle connection but connects to MS SQL Server 2005 Express version locally. Error messages are different according to the connection string though I don't think it makes difference:
ConnectionString = <add key="Databasehandtool1" value="Data Source=.SQLEXPRESS;Database=handtool;SSPI=true" />ErrorMessage from VS2008 ="Unable to get records. Object reference not set to an instance of an object."
ConnectionString = <add key="Databasehandtool1" value="Data Source=.SQLEXPRESS;Database=handtool;User Id=handtool_DB;Password=mypassword" />ErrorMessage from VS2008 = "Unable to get records. Unable to connect to database. ORA-12154: TNS:could not resolve the connect identifier specified." By the way, the application was generated from IronSpeed 5.1 Enterprise. My development environment is : VS2008, SQL2005 EXPRESS, Windows XP SP2, ASP.NET 2.0
We have actually an Oracle server in the network though. My gut feeling is that something might have changed in my network server during the night but how come it can possibly affect my application running on my local PC. I checked the connection of local SQL Express Server from SQL Server Management Studio and it connected well with UserID=handtoo_DB and showed all tables and stored procedures required for the application. So there is no problem in SQL Server database side.
I would welcome and appreciate any input.

Hi,
This might seems a little 'out there', but has anyone tried doing ETL from an Oracle 10g ODS into an Oracle 10g DW, and from there into SSAS2005 cubes?

I currently have a DTS package that will transfer tables from an Oracle db to SQL 7. I am using the Oracle ODBC connection and have connected with the owners login and password. When I run the package through DTS, it runs successfully. However, when I try to run it as a scheduled job, it fails each time. I assume that this has something to do with connecting to Oracle. It's hard to figure out because SQL says only that the job failed. Has anyone else run into this issue?
