New to SQL but want's to learn!

Hi,

I was wandering if anyone could please recommend a good book to learn the basics of SQL 2000? I have made connections etc to a sql db through Visual Studio but would really like to read up on the subject and get a complete grounding on the subject. And also prepare me for the exam 70-229.

Many thanks,
James

Hi

If you need to learn the exam for SQL, you are best buying the Microsoft suite of books for that exam but I can tell you this, it is not easy AT ALL.

To learn SQL, its best looked at examples, reading books again and trial and error.

C-sharp corner website is a good place, but also posting here is a good idea too and I am sure many people will help you out.

There is alot of ground to cover, so start with the basics and move on upwards.

New SQL worm? getting multiple, continuous connections from random IP's for last 4 days

Our bandwidth usage tripled since this started happening. We get
about 1 new attack daily. To stop the attacks we either block the IPs
on the router or email the ISP to get the guy off the network. This
is happening to every SQL server on the network. Seems to be scanning
for open port 1433.
Example;

New Database

I want to design a new database. When I right-click on 'Data Connections' in the Database Explorer from VB I notice that the 'Create New SQL Server Database...' is greyed out, so I can't create a new database.

What is going wrong here, please help.

It could be that your login account does not have permissions to create new databases on the server.|||

Thanks, but I found out that I can create it in an other way;

- name a new application and add a SQL Database from the templates.

But in the menu, that appears after right-click on "Data Connections' in the Database Explorer in VB the 'Create New SQL Server Database...' is still greyed out, that I don't understand why this is.

I am the only user of the computer, so I think I would have permission to create a new database, or not?

I have set the user instances in SQL Server on enabled with;

exec sp_configure 'user instances enabled',1 and reconfigure

Must I still do something else?
