What is a deference when you create a database in SQL server management studio or create it on visual studio

because I see in your book beg asp.net 4.5 you create the database in SQL server management studio but in older version you create it from VS (Right-Click the App_data folder and then chose add new items then SQL data base)

In beg asp.net 4.5 you create database in SQL server management studio after create the database (you say for us) press Ctrl+O and you select folder has name -create planet wrox- Why?

what the best way to create database on SQL server management studio or on VS(visual studio)
thanks

It's the same thing, more or less. When you add it in SSMS, it gets attached to SQL Server and remains attached; when you use VS it's set up to attach to SQL Server dynamically using te attachdbfilename option.

>> after create the database (you say for us) press Ctrl+O and you select folder has name -create planet wrox- Why?

No idea what that means.

First I sorry ...my English is very bad

>> after create the database (you say for us) press Ctrl+O and you select folder has name -create planet wrox- Why?
I mean
In chapter 12 introduction to database (beg asp.net 4.5) try it out creating the sql server sample database section number 6 ....you say : Press Ctrl+O to bring up a dialog box that lets you select a fi le. Browse to the folder
C:\BegASPNET\Resources\Chapter 12. If you don’t have this folder, refer to the Introduction of this book to learn how to acquire the code that comes with this book. Select the Create Planet Wrox Database.sql file.

what this file kind it's not look like .mdf ...how you create it..

I hope to understand my bad explanation

I am still not entirely sure what you're asking, but I think you're referring to the .sql file that ships with the books code. That's just a script file that I created to quickly create a new database and objects to get started. You can create the same script for your own database by right-clicking an existing database and then choosing All Tasks | Generate Scripts.

Cheers,

Imar
