Answer 1

Last_Insert_ID();

Gives you the last primary key id, you can simply append this on the end of your current insert and the key value will be returned from your insert.

here is a C# example:

tring sqlIns = "INSERT INTO table (name, information, other) VALUES (@name, @information, @other)";
db.Open();
try
{
 SqlCommand cmdIns = new SqlCommand(sqlIns, db.Connection);
 cmdIns.Parameters.Add("@name", info);
 cmdIns.Parameters.Add("@information", info1);
 cmdIns.Parameters.Add("@other", info2);
 cmdIns.ExecuteNonQuery();

 cmdIns.Parameters.Clear();
 cmdIns.CommandText = "SELECT @@IDENTITY";


 // Get the last inserted id.

 int insertID = Convert.ToInt32( cmdIns.ExecuteScalar() );


 cmdIns.Dispose();
 cmdIns = null;
}
catch(Exception ex)
{
throw new Exception(ex.ToString(), ex);
}
finally
{
db.Close();
}
