Thank you for the right guidance.. and quick reply.
I wanted to ask, Is this correct way to validate?
Any ways, you have cleared my doubt.
As you said we can also validate in stored Proc as well. how to do that?

Just like you validate anything else. You use conditional statements.
IF @someValue > validRange
BEGIN
-- Put code here to handle invalid data.
-- e.g. Could RAISEERROR
-- Could return a value indicating an error
END
ELSE
BEGIN
-- The data is correct. Apply it to the database
-- e.g. INSERT/UPDATE/DELETE
END

Hi,
I need some help to clarify some confusion I have. If I access some data from the db and then create objects which hold the data--for example, access the customer table and create a customer object--am I using Connected technique or Disconnected? My understanding is I am using disconnected, however my teachers disagree.
I think to use connected technique I will query the db and keep connection open and every time a change is made it is made directly in db.
In other words, if the changes are made anywhere except the data storage source--the database in this case--then it is disconnected.
Furthermore, when you bind controls to the db, is it using connected or disconnected?
Please write a detailed answer and you can assume I am well familiar with ADO.NET.

It is best practice to open the database only when you need to. Open it, do what you need, then close it. If you keep open persistently, then you can run into problems having too many connection pools...

Thanks but that is not the answer to my question.

Whether you're disconnected or connected, you'll obviously need to access the data to create your object. The difference lies in what you do next.
If you leave the database connection open and and write changes to the object back to the database immediately then you are working in a connected state. If you close the database once you've created your object, do some processing with it and then re-establish a connection to the database to write the changes back then you're disconnected.
The answer to your question about binding will be answered in the way you've implemented your system; as you should know, working in a connected state is generally considered bad practice (though there are cases where it is required). In general, if you can get away with only connecting to the database at the start and end of an operation you should probably do that.
It definitely isn't definatley

Good clear answer! Your answer goes in agreement with most texts I have read but the teachers think otherwise. This proves the teachers are wrong.
Thanks

Hi All,
I am trying to display a list of databases in SQL Server 2005. When I used to use MySQL I used a SHOW DATABASE which returned a list of databases.
With SQL Server 2005 this command is not accepted. Can I perform the same list in SQL Server ?

exec sys.sp_databases is a stored procedure that will list all the databases for you...

There's numerous ways to do this. Look into the Cryptography namespace in .NET.

I have 3 Tables (Person-1------1->Employee-1------*>Career)
an employee can have multiple Career. I created the sql statement below
to return some information on an employee
##################################################
select p.FamilyName,
p.AddressLine1,
Career.CareerDescription
from Person as p
inner join Employee on Employee.EmployeeID =p.PersonID
inner join Career on Employee.UniqueIdentifier = Career.ParentIdentifier and Career.PrimaryPostYN = 'Y'
###############################################
The "Career.PrimaryPostYN = Y" indicates which post is active for an employee with multiple career.
So only one post should be active at any one time all other should be set to "Career.PrimaryPostYN = N"
QUESTION:
If in a freak case, if an employee has multipe career and all record for that person is set to "Career.PrimaryPostYN = Y". In such a case i want to return the first case where "Career.PrimaryPostYN = Y"
How do i alter the above statement to do this?

depending on your dbms you can use "select top 1 p.FamilyName..." (mysql, sql server) or "select ... where rownum=1" (oracle)
but you should think about how to identiy which record should be the one you want to get. maybe some sorting is needed?
|
|
|
|
|
If i use "select top 1 p.FamilyName" all the other valid Employee in the select statement will not be returned.It will only return one record set

What is your question? You want to write a delete trigger but don't know how? Have you tried reading the documentation[^]?
