Re: Most Efficient Way to Insert 10 - 15 Rows

2010-03-21T18:23:19Z

After thinking about this, I'm deciding the best way is probably to just
create one long query string with each INSERT statement separated with a
semicolon. This will reduce the number of round trips to 1.
In fact, SQL 2008 even has a shortcut to make this every more efficient. For
more info about that, see:

Most Efficient Way to Insert 10 - 15 Rows

I'm an experienced programmer with limited database development. Most of my
database work involves using query strings or stored procedures or to update
data or populate a SqlDataReader object.
Now, I need to update 10 - 15 rows. I know I can execute 10 - 15 separate
queries but this is in a Web applications and now I'm wondering if there

You can use several methods to enumerate SQL Server instances. Here are a
couple:

To determine whether a specific instance contains a certain database, you
can connect to the instance's master database and query the sys.databases

Hi
Is it possible to check in .net;
1. If sql server 2008 express is installed on a machine?
2. The name of sql server 2008 express instance or instances?
3. If a particular sql server 2008 express instance contains a specific
database?
Many Thanks

There are a number of issues with Jet behind a web server.
1. Jet is not thread-safe, which can be a problem for web servers,

That's ridiculous. There are probably thousands of small websites tunning on
Jet databases. I know of several, one of which ran for 8 years getting as
many as 5,000 hits a day. Eventually that company sold out and the buyer
incorporated the data into a much larger website. As recently as 1 year ago

No, he's not. He's using a Jet/ACE database, which is the first

SELECT @@IDENTITY is, in fact, supported by Jet/ACE. I don't use ADO

Um, no, you can't do that. Look at the first line of the post you
quote:
"insert a record into an access table" means that you can't combine
multiple SQL statements, because Jet/ACE does not (and never has)
supported this.
Until A2010, Jet/ACE has nothing approaching stored procedures

I don't know all of the details and I am not sure I would agree with the
solution, but when you are dealing with a fixed, small set of assets,
sometimes it is easier to do what you are familiar with. Ultimately, in
software, the questions are:
1. Does it work now?
2. Will it work for the future?
