MySQL has an event scheduler which can be used to fire off tasks at specified times or intervals.
|
|
|
|
|
Triggers execute in response to certain events when INSERT, UPDATE or DELETE
|
|
|
|
|
So in this case I cant use triggers..right?

I think you can create a stored procedure for the insertion and call it from a SQL job that's it;

Hi uglyeyes--
You have been a member long enough that CodeProject is not here to answer generic questions such as these. Your question is one where most would probably tell you to "just Google it." Creating a basic database and its tables is part of the learning process. Sit down, take some time, and think it out.
|
|
|
|
|
What exactly is your question?
How to create table called employee, timecard etc in some database?
or
You are looking for guidance related to database design?

u can create this sample tables
CREATE TABLE [dbo].[ATTENDANCE](
[AttendanceID] [int] IDENTITY(1,1) NOT NULL,
[EmployeeID] [int] NULL,
[AttendanceCreatedDate] [datetime] NULL,
[AttendanceCreatedByUserID] [int] NULL,
[AttendanceDate] [datetime] NULL,
[InTime] [datetime] NULL,
[OutTime] [datetime] NULL,
[WorkDuration] [int] NULL,
[IsOverTime] [bit] NULL CONSTRAINT [DF_Attendance_IsOverTime] DEFAULT ((0)),
[AttendanceComments] [varchar](1000) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
CONSTRAINT [PK_Attendance] PRIMARY KEY CLUSTERED
(
[AttendanceID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY],
CONSTRAINT [UK_Attendance] UNIQUE NONCLUSTERED
(
[EmployeeID] ASC,
[AttendanceDate] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

Hi Guys,
thanks for your response. I should have been more specific. I have already created few tables which are as below.
Employee, EmployeeType, Jobtitle,

timeCard(TimeCardId,PeriodId,EmployeeId,Date,StartTimeAM,EndTimeAM,StartTimePM,EndTimePM,BreakTaken,UpdatedDate,IsApproved)
period

for you to understand I have provided columns of period and timecard. this web application is used by hospitality industry.
employee works shifts like 7am-12pm and 6pm-2am
Now, I am thinking I shouldnt store computed values.
My problem is how do i work it out below:
If they work after mid-night they should get penalty and those two hours after midnight should be moved to record
also I dont know how to calculate their pay.
could you please help?
|
|
|
|
|
Ok, to simply it. how can I compare the time value as an input. my idea is if they type endtime anything bigger than 12.00am I need to compare mid-night time and @endtime, if @endtime is after midnight I need to add to append the hours next day in next row.
declare @starttime smalldatetime
declare @endtime smalldatetime
set @starttime='18:20'
set @endtime ='2:00'
print DATEADD(hh, DATEPART(hour,@EndTime), DATEADD(mi,DATEPART(mi,@EndTime),DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0)) )
print DATEADD(dd, DATEDIFF(dd, 0, GETDATE()),0)
Hope that makes sense?
thank you

To make your design more flexible, you need to implement a parent / child relationship where the master is the Timecard and the child records represent slices of time within that timecard. Each time slice can have attributes like Paid/Unpaid, Payrate, Workcode (Work, Absence, Break), Absence code, start time, end time.
For example:
WORK 7:00 - 9:00
BREAK 9:00 - 9:15
WORK 9:15 - 12:00
BREAK 12:00 - 13:00
WORK 13:00 - 17:00
Consider going to CodePlex to see what other people have developed, there may be a solution already out there.

Hi, thanks I went to codeplex but I couldnt find the solution i was looking for. could you please give me an idea how the table relationship might look like between timecard and time slices. thanks once again
|
|
|
|
|
Here is a rough idea of how you could design a time keeping database ...
Table: Timecard_Header
HID - Primary key Auto generated sequence number. (Header ID)
EMPID - Key to the employee table
TCDATE - Timecard date
TIME_IN - Datetimestamp of when the timecard begins (shift start) Include the date portion incase the shift begins at 11pm and runs across midnight
TIME_OUT - Datetimestamp
Table: Timecard_Details
DID - Primary key. Sequence number (detail ID)
HID - Foreign key reference back to the header record
TIME_START - Beginning time for this time slice
TIME_END - Ending time for this time slice
TDTYPE - Timecard deail type (Use this to indicate Work, Break, Absence, etc)
TDCODE - Used as a further explaination of the type, for example Absence - Vacation or Absence - Jury duty
PCODE - Paycode (0 - Unpaid, 1 - Regular pay, 2 - Overtime, 3 - Doubletime, etc)
PRate - Pay rate show the actual rate paid for this time slice. $10/hr Regular pay or $15 / hr for overtime
This should give you an idea of one way of looking at the data, you should extend this model to meet your requirements.

This should work, but it keeps returning a "could not be opened. Operating system error code 5(Access is denied.)."
select * from Openrowset (BULK '\\nvBeast\dropzone\img.jpg',SINGLE_BLOB) AS [Image]
Googling shows that many have the same problem, but I could not find any answers.
Anyone got a clue?

OPENROWSET: Includes all connection information necessary to access remote data from an OLE DB data source. This method is an alternative to accessing tables in a linked server and is a one-time, ad hoc method of connecting and accessing remote data using OLE DB. The OPENROWSET function can be referenced in the FROM clause of a query as though it is a table name. The OPENROWSET function can also be referenced as the target table of an INSERT, UPDATE, or DELETE statement, subject to the capabilities of the OLE DB provider. Although the query may return multiple result sets, OPENROWSET returns only the first one.
If you use any network path, please confirm that your SQL login user is permitted to perform bulk load on the Operating System.

Hi there,
I have a generic class called Product that has general properties that each product will have. Then I have a class called Book, and Computer. This was easy to do in C# code, but now I have to create the table structures. I'm not sure what is the best way to do it? I was thinking of creating a table called Product, and a table called Book. And then have a product identifier in the Book table to reference the Product table? What will the relation be between these 2 tables? 1:1? Can someone please give me some direction as to what to do and what is the best way of doing it?
Regards
Brendan

Book should not be a table, it is a TYPE of product (as is Computer). If you go down the path of having a table for each product type (because each product type has different attributes after all) then you will get your self into a maintenance (and data) nightmare.
Have a product table with all the general attributes as you have done, add a large description field and see if that will meet your needs.
IF you absolutely MUST have additional attributes you might consider an attribute type and attribute table but this is going to add a level of complexity that will make support difficult.
There are entire books written and consultants make fortunes writing product structures so don't be scared to experiment.

Thanks for the reply. Book was just an example. There will be other product types as well. Like computers, clothes, etc etc. So I think it is a little impractical to have all the attributes in one table. Or what do you think?
What product structures are you talking of? Give some examples?
|
|
|
|
|
The structure should be something like this (as Mycroft suggested):
ProductType ' (Book, Manchester, Cookware, ...)
ID INT IDENTITY(1,1) PRIMARY KEY,
Name VarChar(50) UNIQUE NOT NULL
ProductCategory ' (Fiction, NonFiction, Sheets, Pillow Cases, Pots, Pans,...)
ID INT IDENTITY(1,1) PRIMARY KEY,
ProductType_ID INT NOT NULL FOREIGN KEY REFERENCES ProductType(ID),
Name VarChar(50)
Product
ID INT IDENTITY(1,1) PRIMARY KEY,
ProductCategory_ID INT NOT NULL FOREIGN KEY REFERENCES ProductCategory(ID),
Name VarChar(50) NOT NULL
...
...
To add additional attributes, extend this to Properties...
ProductProperty ' (Price, Dimension, Volume, ...)
ID INT IDENTITY(1,) PRIMARY KEY
ProductType_ID INT NOT NULL FOREIGN KEY REFERENCES ProductType(ID),
Name VarChar(50) NOT NULL,
UOM VarChar(20) NOT NULL,
Description VarChar(50)
ProductPropertyValue
ID INT IDENTITY(1,1) PRIMARY KEY,
ProductProperty_ID INT NOT NULL FOREIGN KEY REFERENCES ProductProperty(ID),
Product_ID INT NOT NULL FOREIGN KEY REFERENCES Product(ID)
Value VarChar(MAX)
Wire these together with Foreign Keys and you are away - As Mycroft said, this adds aonother layer of complexity.
