Attendance System

Dec 13, 2007

Hi everyone,
I am working on a web based tool to handle attendance and leaves.
Our working hours start at 9:00 but managers will be allowed to set different starting hours for some of their staff.
I will eventually need to view the employee attendance record over a period of say a month.

My question is about storing the modified working hours
I can either:
1) record the (employee name, starting date of modified time, end date of modified time, new start time) as one record and use the f_table_date function

OR

2) Generate the days between the start and end in the application front end and store values for each day in the modified working table.

I feel option 2 will be easier to calculate the reports and prevent managers from inserting modifed times for the same employees in overlapping periods but also think it's a bit not effecient to generate day values when the start and end date would be represent the same information.

Any guidance or am I not clear?
Thanks

Storing Attendance - Design Question

Mar 16, 2006

I'm new to database design and i need som advice concerning the design of my tables.
What I want to accomplish is this:
A attendace tracking system that allows tracking of meeting attendance. The project manager is setting up a meeting and after the meeting was held he/she reports who in the project team was at the meeting. It should then be possible to track the meeting attendance of the different team members.
I have a table containing the data for the team members and i thought of adding an "attended meetings" field but the field is actually a number of fileds depending on how many meetings the person has attended so far. How do I accomplish the described functionality?
Can someone pleas give me some advice
Thanks

SELECT Statement With An Attendance Table

Feb 4, 2005

I have a table that contains the following structure and information:

Code:

UID Member_Number Time_Stamp Status Reason Event Reg F_Name L_Name
18772054062/3/2005 11:48:27 AMInNonenoneNoneWendyBoud
86930082522/3/2005 12:39:35 PMInNonenoneNoneJeremyAhlman

128772054062/3/2005 12:46:25 PMOutNonenoneNoneWendyBoud

I need to be able to take this information and display it in a data grid so that on each row I see the Member Number, First and Last Name and the In and Out Time.

I am not sure how to group the In and Out times together so that the query knows which time out corresponds to which time time for the member?

Any help is greatly appreciated!

Jan 4, 2009

I have created a database table in MSSQL 2000 like this

Right now i am using a stored procedure which traverses through each record and does the job.

Is there any way to do it with Pivot, or queries instead of cursors.

How To Find Conditions Across Rows (attendance)

May 4, 2006

Hello,I need to find students that have 4 consecutive absences. When astudent is absent 4 times in a row, they can be dropped from the class.My class attendance file contains each attendance by date and whetherthey were present or not. When the student has 4 consecutive value 1(absent) for a given session and a given class the are considered to bedropped.If I needed to know the total number of absences, I know I could groupand summarize, but this one has the consecutive twist.Table:CREATE TABLE "dbo"."clsatt"("FULL_CLASS_ID" CHAR(15) NOT NULL,"STUDENT_ID" CHAR(20) NULL,"SESSION_ID" CHAR(10) NULL,"MEETING" SMALLINT NOT NULL,"PRESENT" CHAR(2) NOT NULL);Present value of 1 is absent, value of 2 is present (3 means holiday)Classes typically meet 12 times.I would want something likeFULL_CLASS_ID, STUDENT_ID, SESSION_ID, 'Dropped'as the output.Notice in the example the first student was absent the last 4 meetingsThe second student 5 absensesand the third student was totally absentIn these three examples, they are flagged as dropped.TIARobInserts:---------------------------------------------------------------------------------insert into clsatt values ('BUS100','1675812194','200203',1,'2')insert into clsatt

Attendance Records - Bulk Insert In Student Database

Apr 5, 2012

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?

SQL Server 2012 :: How To Calculate Attendance For Single Student For Yearly Basis

Jul 2, 2015

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.

System.Security.SecurityException: Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data

I have created a windows library control that accesses a local sql database

I tried the following strings for connecting

I am not running the webpage in a virtual directory but in

the error

I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security

I think that a windows form connecting to a sql database running in a webpage should be simple

to configure what am I missing?

Sql Server 2005 Operating System Compatibility Warning Message In System Configuration Check

Apr 3, 2007

Ok guys, I am trying to install Sql server 2005 on Vista but I am still stuck with this warning message in the System Configuration Check during Sql server 2K5 installation :

SQL Server Edition Operating System Compatibility (Warning)
Messages
* SQL Server Edition Operating System Compatibility

* Some components of this edition of SQL Server are not supported on this operating system. For details, see 'Hardware and Software Requirements for Installing SQL Server 2005' in Microsoft SQL Server Books Online.

Now, I know I need to install SP2 but how the hell I am going to install SP2 if Sql server 2005 doesn't install any of the components including Sql server Database services, Analysus services, Reporting integration services( only the workstation component is available for installation)?

Any work around for this issue?

P.S.: I didn't install VS.NET 2005 yet, can this solve the problem?

Thanks.

Determining What Are System Objects In Sp_help Or System Tables

Jul 20, 2005

Hi,I have a few things on my databases which seem to be neither true systemobjects or user objects - notably a table called 'dtproperties' (createdby Enterprise manager as I understand, relating to relationship graphingor something) and some stored procs begining with "dt_" (some kind ofsource control stuff, possible visual studio related). These show up whenI use"exec sp_help 'databaseName'"but not in Ent. Mgr. or in Query Analyzer's object browser, and also notin a third party tool I use called AdeptSQL. I am wondering how thosetools know to differentiate between these types of quasi-system objects,and my real user data. (This is for the purpose of a customized schemagenerator I am writing). I'd prefer to determine this info with systemstored procs (ie sp_help, sp_helptex, sp_...etc) but will dip into thesystem tables if needed.Thanks,Dave

@PARAM1 : Unable To Cast Object Of Type 'System.Data.SqlTypes.SqlInt32 To Type System.IConvertable

Apr 23, 2007

I get the following message in the vs2005 querybuilder when i do a preview:

***********************************
SQL Execution Error.

Executed SQL statement: SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = @PARAM1)

Error Source: SQL Server Compact Edition ADO.NET Data Provider

Error Message: @PARAM1 : Unable to cast object of type 'System.Data.SqlTypes.SqlInt32 to type System.IConvertable'.
****************************************

The same querypreview works fine without the parameter:

SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)

Can anybody tell me why this is?
And tell me a way to get the tableadapter working?

I created a .net console application within which I connect to a sql server (not local) as follows,

SqlConnection conn = new SqlConnection(conn_str);

conn.Open();
.
Everything works fine when I run it from my computer. When I try to run it from a network share I get the following error,

Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I am using Visual Studio 2005 and .Net framwork v2.0.50727.

Does anybody know a fix to this problem?

Unable To Cast Object Of Type 'System.String' To Type 'System.Web.UI.WebControls.Parameter'.

Jun 19, 2008

I'm getting this error on a vb.net page the needs to execute two separate stored procedures. The first one, is the main insert, and returns the identity value for the ClientID.

Unable To Cast Object Of Type 'System.DBNull' To Type 'System.Byte[]'.

Aug 13, 2007

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

Peer To Peer Replication - Quiescing A System ( Quiesce A System )

Oct 23, 2007

MS documentation is short when it comes to explanation of Quiescing a system for peer to peer replication. It seems that for any change the whole p2p machine has to stop ? This would cripple our development/releases... Is it really the case ?
Can all p2p nodes be quiesced except one, the one when I would also make changes ?
i.e. N1 <> N2 <> N3 I would stop inserts/updates/deletes for N1 & N3 and keep inserting/updating/deleting for N2 as I'm making schema change on N2 (additional table, additional field etc). Would it work ?
Also, would I need to stop selects for N1 & N2 ?

Thank you.

'((System.Exception)($exception)).Message' Threw An Exception Of Type 'System.NotSupportedException'

Jan 16, 2008

Greetings everyone, I am attempting to build my first application using Microsofts Sql databases. It is a Windows Mobile application so I am using Sql Server Compact 3.5 with Visual Studio 2008 Beta 2. When I try and insert a new row into one of my tables, the app throws the error message shown in the title of this topic.
'((System.Exception)($exception)).Message' threw an exception of type 'System.NotSupportedException'

My table has 4 columns (i have since changed my FavoriteAccount datatype from bit to Integer)
http://i85.photobucket.com/albums/k71/Scionwest/table.jpg

Account type will either be "Checking" or "Savings" when a new row is added, the user will select what they want from a combo box.

Next is a snap shot of my startup form.
http://i85.photobucket.com/albums/k71/Scionwest/form.jpg

Where it says "Favorite Account: None" in the top panel, I am using a link label. When a user clicks "None" it will go to a account creation wizard, and set the first account as it's primary/favorite. As more accounts are added the user can select which will be his/her primary/favorite. For now I am just creating a sample account when the label is clicked in an attempt to get something working. Below is the code used.

private void lnkFavoriteAccount_Click(object sender, EventArgs e)

{

FinancesDataSet.BankAccountRow account = this.financesDataSet.BankAccount.NewBankAccountRow();

account.Name = "MyBank Checking Account";

account.AccountType = "Checking";

account.Balance = Convert.ToDecimal("15.03");

account.FavoriteAccount = 1;//datatype is an integer, I have changed it since I took the screenshot.

financesDataSet.BankAccount.Rows.Add(account);
//The next three lines where added while I was trying to get this to work.
//I don't know if I really need them or not, I receive the error regardless if these are here or not.

this.bankAccountTableAdapter1.Update(financesDataSet);

this.financesDataSet.AcceptChanges();

refreshDatabase();

}

the refreshDatabase() code is here:

private void refreshDatabase()

{

this.bankAccountTableAdapter1.Fill(this.financesDataSet.BankAccount);

//Aquire a count of accounts the user has

int numAccounts = financesDataSet.BankAccount.Count;

//Loop through each account and see which one is the primary.

for (int num = 0; num != numAccounts; num++)

{
//Works ok in frmMain_Load, but when my lnkFavoriteAccount_click calls this, it throws the error.

if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)

{
//Display the primary account on our home page. User can click the link label & be taken to their account register.

this.lnkFavoriteAccount.Text = this.financesDataSet.BankAccount[num].Name.ToString();

this.lnkFavoriteFunds.Text = this.financesDataSet.BankAccount[num].Balance.ToString();

break;

}

}

}

and my form_load code

private void frmMain_Load(object sender, EventArgs e)

{

refreshDatabase();

}

So, when I click on the lnkFavoriteAccount label, and my new row gets added, the app stops at the following line in my DataSet.Designer

[global:ystem.Diagnostics.DebuggerNonUserCodeAttribute()]

public byte FavoriteAccount {

get {

try {

return ((byte)(this[this.tableBankAccount.FavoriteAccountColumn]));

}

catch (global:ystem.InvalidCastException e) {
//Stops at the following line, this error was caused by 'if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)'

throw new global:ystem.Data.StrongTypingException("The value for column 'FavoriteAccount' in table 'BankAccount' is DBNull.", e);

}

}

set {

this[this.tableBankAccount.FavoriteAccountColumn] = value;

}

}

I have no idea what I am doing wrong, all of the code I used I retreived from Microsofts help documentation included with VS2008. I have tried used my TableAdapter.Insert() method and it still failed when it got to

if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)

in my refreshDatabase() method it still failed.

When I look, the data has been added into the database, it's just when I try to retreive it now, it bails on me. Am I retreiving the information wrong?

Thanks for any help you guys can offer.
