Is There A Difference?

Mar 10, 2004

Is there really a difference of approach?

I have several things to consider in an estimating database. Production, Shipping, Field Work, Field Hardware, etc...

All of the above have account numbers. Now I was wondering, would there be any benifit to having one table or several tables?

One Table Example

Account (PK) | Category | Description

or

Multiple tables

tbProduction
Account (PK) | Description

tbShipping
Account (PK) | Description

tbProducts
Account (PK) | Description
etc.....

I like having the tables split up and/or all in one.

Any thoughts, pros / cons?

Difference

Apr 24, 2007

Are SQL Server Express & SQL Server 2005 one & the same thing? Or is the former a part of the latter? Actually when I was downloading Visual Web Developer 2005 Express, I was given the option to download Microsoft SQL Server 2005 Express Edition as well; so I am getting confused between SQL Server Express & SQL Server 2005.

I installed SQL Server 2005 in my WinXP Pro m/c. from the Microsoft website (after re-installing WinXP Pro since XP became corrupt). Earlier I used to login to Management Studio Express using my m/c. name followed by a followed by SQLEXPRESS as the server name. So if my m/c. name is MyPC, then I used to login to Management Studio Express using MyPCSQLEXPRESS as the server name but now when I try to login to Management Studio Express using the above server name i.e. MyPCSQLEXPRESS, then an error gets thrown saying

Cannot connect to MyPCSQLEXPRESS.

Now how do I find out what's the server name so that I can login to create & manage databases in Management Studio Express?

Please note that after re-installing WinXP Pro, my m/c. name has remained the same; I didn't change it.

Thanks,

Arpan

Showplan Difference

Mar 9, 2001

Hi,

I have a view in a database called PS_EMPLMT_SRCH_US and it joins around five tables. I have two databases which are identical structures including data. But when run one query
ie "SELECT * FROM PS_EMPLMT_SRCH_US where EMPLID like '00918%' and OPRCLASS like 'ALLPANLS' ",
response time is totally different even though both databases have same data and same indexes. When I looked at showplan and stats time, both are totally different and order of table fetch is totally different. Is there any idea why this difference? Any help would be appreciated.

Here is the show plan info:

Calculate Difference?

Dec 30, 2003

I am having trouble creating a sp for the following situation:

The database contains a record of the mileage of trucks in the fleet. At the end of every month, a snapshot is collected of the odometer. The data looks like this:

Truck Period Reading
1 1/31/03 55102
2 1/31/03 22852
1 2/28/03 62148
2 2/28/03 32108
1 3/31/03 69806
2 3/31/03 52763

How can I calculate the actually miles traveled during the month in a query?

TIA,

Rob
