Student Who Wants To Dba
Jan 10, 2005
i'm currently a student in computer information sciences, and i wanted to give my studying some more focus thus choosing dba. now i'd like to dba but be as broad as possible when i first start out my career. i know some programming languages and recently finished a C# book for doing .net development and a ASP.net book for scripting. but where should i go from here? should i just start studying ms sql server? what about a microsoft certification? i'm very curious to know where the next step in my studying should be, so anyone who was in my shoes, i'd love to hear any information you have to offer. TIA

Hi,I'm finishing up a beginning SQL class where we learned on an Oracledatabase and the transition to working on SQL Server is easy. The next moreadvanced course will be in PL/SQL, but I know I will be working on SQLServer in the workplace, so my question is if I should take this course.Will I benefit from the basic philosophies that will be covered, or will itjust make a transition for me more difficult? Will it be partly a waste oftime and money and I'd be better served getting a book and self teachingmyself? I know that in a greater sense learning something isn't necessarilya waste, but I mean from the perspective of my goal of being able to use SqlServer, will this course be useful?thanks.

I am starting a class on SQL Server, and my school wants me to builddb's either on campus or remotely at my home connecting to their SQLServer Enterprise.Will I be okay to use Developer Edition at home to connect with anEnterprise-licensed SQL Server on campus, to build databases,sprocs, .net apps that connect to the database stored on my school'sserver?I would rather avoid the Express edition.thanks

I'm a kid and I'd like to know what kind of work a database administrator does. It would be great to learn from a real database administrator how you spend your typical day at the office. What are some of your main duties? Thanks so much in advance.

I want to calculate average of grades of each student and get the highest one with SQL command.
I have 2 tables:
Students:
*StudentId
*StudentName
___________
Grades:
*StudentId
*Grade
___________
I need to calculate average of each student and then get the highest.
My try:
Code:
SELECT Students.StudentId,Students.StudentName,AVG(Grades.Grade) AS avg_grade FROM Students s JOIN Grades g ON Grades.StudentId =Students.StudentId
GROUP BY Students.StudentId, Students.StudentName
ORDER BY avg_grade
LIMIT 1 FROM Students;
I encounter problem with this code, maybe it's Completely wrong...

My working table:
CREATE TABLE [dbo].[Name_ID4](
[id_num] [decimal](18, 0) IDENTITY(1,1) NOT NULL,
[student_last_name] [varchar](30) NULL,
[student_first_name] [varchar](30) NULL,
[student_middle_init] [varchar](1) NULL
[local_student_id] [bigint] NULL,
I need to identify only the students with more than one local_student_id and the associated local_student_id's.
I can identify the students with two id's but not the associated id's
SELECT COUNT(*) AS Dup_Num,
rtrim(student_last_name),
rtrim(student_first_name),
rtrim(student_middle_init),
from Name_ID4
group by
student_last_name,
student_first_name,
student_middle_init,
having (count(*) > 1)
order by student_last_name, student_first_name, student_middle_init
Thanks

I am stumped on a set-based approach for this one.
A cursor approach is straightforward enough, but i want to avoid that.
Here's my table:
create table StudentScores
(
id int primary key identity(1,1),
student_id int not null,
score int not null
)
with some sample data:
insert into StudentScores (student_id, score)
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 88 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 98
What I want is, for each student, what is their 90th percentile score?
For a given single student, one possibility would be:
declare @studentid int
set @studentid = 2
select top 1 @studentid as student_id, a.score as [90th percentile score]
from
(
select top 90 percent score from StudentScores
where student_id = @studentid order by score asc
) as a
order by a.score desc
But I want this for all students, and not use a cursor.
Any ideas?
Thanks!

I am trying to find out the the Average number of contact hours per student. in Reporting Services 2005. The contact hours is the in the Totaltime field
Is this formula correct
=Sum(Fields!TotalTime.Value)/Avg(Fields!TotalTime.Value) is in the =Fields!StateServices.Value Group
My groups are
=Fields!Student_ID.Value
=Fields!StateCategory.Value
=Fields!StateServices.Value
Code:
SELECT Student_ind.[Student ID], ParticipantActivity.ActivityDate, School_tbl.[Studentschool Id], School_tbl.schoolID, ParticipantActivity.TotalTime,
ParticipantActivity.Services, ParticipantActivity.Activity, Student_ind.SSID, ParticipantActivity.StateCategory, ParticipantActivity.StateServices
FROM ParticipantActivity INNER JOIN
School_tbl INNER JOIN
Student_ind ON School_tbl.[Student ID] = Student_ind.[Student ID] ON ParticipantActivity.[Student ID] = Student_ind.[Student ID]

I have a csv that contains attendance records that I get daily from a 3rd party grade book solution. I need to import directly into the attend table in our student database.
Code:
Attend File-"1112","0021","404550","20120402","ABU","2300000","06","05"
The file is setup as follows, School Year, school number, student_id, absence date, absence code, course number, section number.
I need to check the student schedule to see if they are scheduled for that class when the import runs. So if they had a schedule change in the middle of the day it won't post attend to a dropped class.
I have done something similar to this before with the way I export teachers out to our grade book. I have it check the master schedule to see if the teacher is teaching at least one class, that way it won't export tutors and office staff to the grade book. I used the script below to do that but not sure who to apply it to a bulk insert.
Code:
Script Used to export teachers note last four lines, checks master
USE [GSchool]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[Code] ....
Secondly I need to check the date of the record and overwrite a record if one already exists for that exact course and section for that student, I need this because if they make changes to a previous day from absence un excused to excused I need to get rid of the unexcused by overwriting it.
One more thing that would be nice but is optional, is there a way to send log of errors on the import via email?

In my query, I am showing Student Record and also want to retrieve the last class attended by the student using JOIN to the table (ClassHistory).
Master
ID Student_Name
1 Arindam
2 Brenda
3 Callie
(ClassHistory)
ID Class Year
1 4 2003
1 5 2004
1 6 2005
2 4 2003
2 5 2004
3 4 2003
DESIRED RESULTSET
ID Student_Name Class Record
1 Arindam 6
2 Brenda 5
3 Callie 4
The result is like - Arindam last class was Class 6, while Brenda was in Class 5 and Callie was in class 4.
Please note that the query will b part of a larger query and the Class record to be retrieved from ClassHistory if possible need to be retrieved through JOIN.

I have to calculate the Total number of days present and absent for a singel student.
AS of now i have 3 tables.
1.Daily attendance - Columns -[Guid][,AcademyId],[StudentId],[Date],[Status],[Reason]
2.Student details - Columns - [Guid],[FullName],[DOB],[Address]
3.Class Details - Columns - [Guid],[AcademyId],[Class],[Section],[Startdate],Enddate]
So now i have loaded all the data into the table.
I can fetch the counts for total present and absent
Query i have tried is
Declare
@StudentId Uniqueidentifier ='0B2D4D41-8D33-4D79-A981-03E0F093F458'
Begin
select A.StudentId ,A.Date,Count(Date)Total,B.Guid,
[Code] ....
AS result of this query i get the data.Present count and Absent count from date inserted in Dailyattendance tables.
SO my problem is if the student have promoted to next class then by this query it will count the before year also how do i need to calculate the count according to the Class StartDate and Enddate as i mention in the Class Details table what will be the query.
