I will back Jorgen on this one, do NOT use EF as your data access layer if you intend to become a serious developer who builds data centric solutions. Linq to SQL is basically a disaster wrapped in obscure syntax, learn TSQL and you will reap the benefits your entire career.

There are different installation options for SQL Express - the larger "Express with advanced services" or "Express with tools" downloads include Management Studio, whereas the smaller "Express" download doesn't.
If you've downloaded the version without the tools, there's a separate "Management Studio"-only download available on the same page:

I didn't got, how you compute the years, months and days?

OK...
Get minimum of start (select min(start) from ... where ...)
Get maximum of end (select max(end) from ... where ...)
Do datediff between the two...

thats right in case the periods are connected some cases the periods not connected like
start end

I see...
In that case you can do something like this
select sum(datediff(d, start,end)) from ... where ...

How do you do the calculation? If the number of months comes out at 12 then that is 1 year.

Assuming you are storing the values as DateTime types, then you can just use a simple subtraction to get a difference value, which can be converted to years, months and days.
|
|
|
|
|
You'll need to pick a starting date, since different months have a different number of days.
For example, 30 days from 1st March would be 30 days; from 1st April, it would be one month; from 1st February 2014, it would be one month and two days; from 1st February 2012, it would be one month and one day.

Hi,
I would like to ask how can I make a complete silent installation and configuration for the MySQL server.
i have downloaded the Windows (x86, 32-bit), MSI Installer and I want to make a silent installation for my setup package.

First result on Google for "MySql Windows Silent Install":
For example, to perform a quiet installation (which shows no dialog boxes or progress):
msiexec /i mysql-5.1.73.msi /quiet

Just noting that if your intent is that your application will be doing all of the database administration then choosing a database that is less full featured might be a better option. And choosing an embedded database might be a better option as well.

Not sure. You might need to add a
mysql_set_charset('utf8');
between the connection and the selection of the db.

Hi,
I want to know if there is any way to retrieve an entire row that has a column with least creation time without using top.
Let us take a sample table named Patient
-----------------------------------------------------------
PatientId Observation Time Value
-----------------------------------------------------------
1 Temp 2014-02-19 03:55:00 35
1 Temp 2014-02-19 03:45:00 37
1 Weight 2014-02-19 03:40:00 60
If i am given the PatientId and Observation, I need to retrieve the the row with minimum creation time
For patient id 1 and observation Temp this would be the row
1 Temp 2014-02-19 03:45:00 37
since it has 2014-02-19 03:45:00 as minimum creation time
