Hi All!
We are doing new development for SQL Server 2000 and also moving from
SQL 7.0 to SQL Server 2000.
What are cons and pros for using IDENTITY property as PK in SQL SERVER
2000?
Please, share your experience in using IDENTITY as PK .

When calling the Find function of a DataRowCollection, one has two options:
Overloads Public Function Find(ByVal key As Object) As DataRow
or
Overloads Public Function Find(ByVal keys() As Object) As DataRow
This function is easy to use if the primary key of your DataTable consists
of only one field. How can you use the Find functions if the primary key
consists of two database fields (composite key)?

When it comes to adding records in related tables, Access is really smart.
But when I try to do the same using ADO, I am really stupid.
Say I have two parent tables (eg Course, Student) and one child table
(StudentProgress). The course progress records how a student progresses on
a course. I have one course (History) and one student called Maya. I now
want to record her grade (64). If I do this in Access using a form, then

I am a bit confused in creating a composite primary key. I have three table
with two of the tables containing primary keys. I have two of the tables
(each with a primary key) having one to many relations with the table
containing no primary key. Do I just create two primary keys on the table
that does not contain any primary key for this to become a composite primary
key?
Thank you in advance!
Still a newbie,

Most of the reference books recommend autonum primary keys, but the
Access help says that any unique keys will work.
What are the tradeoffs?
I have several tables that have unique fields. Can I use them as
primary keys or should I define an autonum primary key?
One table has information about the 50 states in the US. The table

I have a BindingSource with an underlying table with two primary keys.
To set the position with one primary key works fine as shown in the code
snippet below:
Dim index As Integer = myBindingSource.Find("ColumnName", myColumnName)
If (index <-1) Then
myBindingSource.Position = index
End If
How should I set the BindingSource.Position with two or more primary keys?
