I was on an interview and one developer asked me:
Suppose three transactions have three different isolation levels, one of them has isolation level
serializable, and all of then hit one table. How will SQLServer handle this?
He said that SQLServer automatically set isolation level for all transactions to serializable.
Is it true?
Thanks Nick

Good fortune came my way this morning I was invited to an interview for a Database Administrator/IT Support position with a local charity.Although my 2 years experience with IT has been mainly supporting desktops Win 98,2K ,XP in a workgroup together with training users on MS Office Professional I decided to go for the database admin/IT support because I want to broaden my experience with IT applications. The objective being to become more marketable to employers.While I definately meet most of the IT support/training requirements for the post a few requirements are making me nervous because I have no experience in them since I believe I may need programming and or other skills which I don't have. The accountabilities that make me nervous are the following :
1. Devise and implement solutions to corrupted data and software inconsistencies or failures of the housing database.
2. Devise and implement solutiions to corrupted data and software inconsistences or failures of the management information system.
3. Devise and deliver reports from the housing database or MIS in order to satisfy the requirements of managers and external regulatory bodies.
4. Test and validate new versions of software.
Do I need database programming skills for these requirement?If not what skiils do I need and what would be the best way of answering quetions about these requiremnts during interview since I have no database admin experience ?
Looking forward to your thoughts on this.

I thought a question about bitwise operations would be good, maybe one about semi-joins. Are there any questions you can think of that will spot the phony pretty quick?
Thanks,

I've met an interview question. How to do when you need to add an normal column to a very large table? what should you do carefully?
Thanks.
I have been asked by a person who is going to interview me to supply this informationl;
'Come prepared to be able to talk me through how to set up an SQL driven .NET website on a server.
You are given a webroot folder containing root files such as the web.config and all the files for a .NET website and a data folder which contains an .mdf and .ldf files.
Talk me through what each of these folders contain and what you would do with them in order to set up the website on a server such that you would be able to open a browser type the URL you have configured and visit that website.'
I come from a Cisco background and no nothing about what she is asking. Is it unreasonable of me to expect to be able to gain this information in 2 days? Can you tell me the best place to look for this knowledge?
Thanks for any help.
hi,
pls help me ,i am going to attend the interview for SQL DBA pls give me a some tips.
Hi,
I will be going for an interview and I heard that the interviewer usually ask one question which is "if a table contains only one field in which normal form it lies.". What I wanted to know is if it is normalized or not if normalized then in which normalized form it will lie and if not lie in any normal form then why?
I would also appriciate if someone can give me some good source for that as well.
Please treat it as urgent as my interview will be day after tomorrow.
Thanks and best regards,

In my experience of going through plenty of interviews, I have came across a question that I am reminded of by someone's signature.
The common question in this instance is:
What is the advantage of a cursor over a stored procedure? Vice Versa?
I could only, in my so few experiences, have answered that stored procedure consumes less system resources than a cursor. The advantage a cursor has is record by record examination and looping capabilities.
Needless to say that whenever asked those questions, I haven't landed the position. So I'm wondering, what is the more appropriate answer?
Does anyone has, a list of interview questions for SSIS? Or can somebody list possible SSIS interview questions?

I have met the interview question, I provide answer like the following from my experience. I don't know it is correct or need to supplement. Thank you for help.
Question: How to identity existing data for updating in SSIS?
Answer:
If you have the same key columns such as primary key or business key, you just use them to identify existing records from data source to destination.
If you use different key columns between data source and destination, you can create permanent link table which will store business key for data source and destination, and you can compare records from linking table when you update data.
