How to insert multiple records with a single query?

Hi,
I've to save a huge number of installments with their other information such as due on blah blah. Now, I want to add the all of these information at once with a single insert query.
How can I do that?

Hi
What is your source data?
If the source is external to the SQL Server (like a log file, Excel, CSV, JSON, XML, external application...) you can and should insert it all using Bulk Insert operation.
Pls clarify what is your source data, and if you need more help using Bulk Insert.

Hello,
Using Oracle 11gR2 on windows 7 client. I have a question on calculating sum() on multiple columns on different columns and store the results in a view.

Will appreciate any help or suggestion.

ThanksLooks like you want a simple group by.
select

     ,      mnth

     ,     sum(actual_missing_package)
from test
group by
     yr, mnth, region
order by
     yr, mnth, region;I wouldn't recommend storing your data for year / month in 2 columns like that unless you have a really good reason. I would store it as a date column and add a check constraint to ensure that the date is always the first of the month, then format it out as you wish to the client.
CREATE TABLE test
     year_month                              date,

You can setStyleName property for chnaging the external css dynamically by using the setStyle() method ...

blendButtonSkin {
    fontFamily: Arial;
    fontSize: 11;
    color: #F1F1F1;
    textRollOverColor: #F1F1F1;
    textSelectedColor: #F1F1F1;
    horizontal-align:center;
    width:150;
    height:30;
    cornerRadius:5;
    upSkin:ClassReference('assets.skins.BlendButtonSkin');

The answer to your question depends on what you ant to do with the DVD.
Do you want a DVD menu, slide show etc.
iPhoto will allow you to burn straight to a DVD. Just select the album you want to burn then go to share in the tool bar and select Burn.

Multiple databases in a single query

I need to query multiple databases in a single query.
e.g.
Database d1 contains table t1 with column id
Database d2 contains table t2 with column id
I need a query like
SELECT * FROM t1, t2 WHERE t1.id = t2.id;
is this possible in jdbc? if yes can anyone help with some sample code?
thanks,
Ashish Saraf

It is not possible using the JDBC API to query tables in two or more databases using a single query. The reason is that a JDBC Connection is made to a single data source.
However, some databases support the idea of federations or linked tables. What you do is inside the database manager link or federate a table that is present in another DBMS. Then, pose a single JDBC query to the one DBMS which will have its own table and links to the external tables.
Another approach is to use a special JDBC driver with a built-in integration engine that will perform a query across multiple databases. In effect, the system poses separate queries to the different databases and integrates and joins the data together for you automatically on the client-side. That is much easier than doing it yourself in code, but that is also possible for simple queries.
As part of my research program, we have released a shareware version of the UnityJDBC driver that can query multiple databases using a single SQL query. For more information, see:

How to use multiple hierarchies for a single char in single query

Hi,
Is there any way that we can use multiple hierarchies for a single char in single query. I tried and it just allows me to select one hierarchy even if I use hierarchy variable.
I have a requirement where user wants to see information related to a cost center with different cost center groups in different hierarchies (every year has different cost center group hierarchies).
Suppose I want to see information related to a cost center from year 2001-2004.in these four year cost center may have been associated to different groups depending upon that year hierarchy. How can I do that?
Thanks
Jona

Nope. Now way to do this.
There is always just one hierarchy assigned to a characteristic. And even if the hierarchy was time dependent, it only reads it for one key date and not according to transaction data.

Beat

If you pass as single string then you might have to split the same at reciever end.
Are you trying any thing specific?

How to add multiple databases for a single frontend

We have a project based on distributed databases and we have to workout on .Net framework.I want to know some information of connecting multiple databases for a single frontend and how can we access them.
If so we have connected 2 databases for a single frontend in future if I want add one more database to it how it will be possible to do it without disturbing the current connectivity.
Please help me in resolving this problem.
Thanks......

hi,
what do you mean by connecting 2 databases? can you explain further?
using entityframework you can connect to different databases
public class CustomerContext : DbContext
public ReportContext()
: base("DefaultConnection")
public DbSet<Customers> Customers { get; set; }
and your connectionstring (config file)
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=D:\\Database\Project.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
you can add more connection strings on it.
