I have an sql table in which i have two columns enq_no and enq_serial.
for a particular enq_no, enq_serial should get incremented by one starting from 1.
What is the best approach to achieve this?
another issue is that after deletion enq_serial should get decremented by one.
How can i get this?
Is after delete trigger could be a good option?
If so? how can i get this with after delete trigger?
How I will create the scheduling system. I have 3 tables related namely employees, schedule and shift. How will I show the data using the relation shift of the table on gridview by this: It will be filtered by datefrom and dateto: Select via calendar ex Datefrom: August 1 Dateto: August15
Then It will show:
EmployeeID Name
1 2 3 4 5 and up to 15
EP9112 Lastname, firstname, Middlename shift shift shift shift shift
with edit when I press EmployeeID their shift.
How can I also format the shift and date by: ex TimeIn: 7:00:00 AM TimeOut: 3:00:00 PM Date: 8/1/2010
When I add it, it will be TimeIn: 8/1/2010 7:00:00AM TimeOut: 8/1/2010 3:00:00 PM.
Do I need to edit my database.
I have a system in which users can enter records into a database via ajax. Each user may hold many values in the database, with different pageId and itemId values. Each user is identified by a GUID set to a cookie. The system needs to prevent the user from entering two pieces of data with the same pageId and itemId, so I've created a script to do two database updates:
Firstly, all records are deleted from the database where the memberGUID, pageId and itemId fields match (i.e. they've already added this item).
Secondly, the record is then recreated.
It all works brilliantly, except when the GUID value is passed into the delete statement, then I just get a caught exception.
So this works:
[Code]....
But this doesn't:
[Code]....
The weird thing is that because the GUID value is being saved in the second database call, it is definitely there and is definitely the right data type etc. Even if I hard-code it into the delete procedure it still causes the whole thing to fail.
why it's failing when I add the GUID parameter in the deletion process?

I need to use a field of 64 bits (32 is not long enough). I used the following page to see the effects of bit shifting when using the Int64 data type:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ Page Language="VB" WarningLevel="1" Explicit="true" Strict="true" %>
<script language="VB" runat="server">

dim bit_no as Integer
dim info as Int64

info = Int64.MinValue
response.write( String.Format( "Int64.MinValue = {0}<br>", info ) )
response.write( String.Format( "Int64.MinValue (binary) = {0}<br>", Convert.ToString( info, 2 ) ) )
response.write( "<br>" )
' Show max value as binary ...
info = Int64.MaxValue
response.write( String.Format( "Int64.MaxValue = {0}<br>", info ) )
response.write( String.Format( "Int64.MaxValue (binary) = {0}<br>", Convert.ToString( info, 2 ) ) )
response.write( "<br>" )
response.write( "Bit Shift Test" )
response.write( "<br>" )
for bit_no = 0 to 63
info = 1 << bit_no
response.write( String.Format( "1 << {0} = {1}<br>", bit_no, info ) )
next

I'm looking for a control I can use in an ASP.NET app for scheduling work shifts. My primary requirement is to have locations on a y-axis, dates on the x-axis, and then at each intersection, have a block divided into shifts, and each shift containing a short (1-3) list of employees working that shift.

View 3 RepliesThe following is a note from Professional ASP.NET MVC 2 by Scott Hanselman ++
You might ask — why did we go through the effort of creating a <form> within our Delete Confi rmation screen? Why not just use a standard hyperlink to link to an action method that does the actual delete operation? The reason is because we want to be careful to guard against Web-crawlers and search engines discovering our URLs and inadvertently causing data to be deleted when they follow the links. HTTP-GET-based URLs are considered safe for them to access/crawl, and they are supposed to not follow HTTP-POST ones. A good rule is to make sure that you always put destructive or data-modifying operations behind HTTP-POST requests.
If web-crawlers and search engine have no access to the page containing deletion button, is it safe to use a standard hyperlink to link to an action method doing the actual delete operation?

View 3 RepliesI have a table(ShiftCalendar) that lists a letter and a datetime:
Shift Date
A 3/2/2010 8:00:00 AM
B 3/2/2010 8:00:00 PM
I can run a select query that looks like this:
SELECT Shift
FROM ShiftCalendar
WHERE (Convert(nvarchar(10), GETDATE(), 101 = Convert(nvarchar(10), Date, 101))
This will return both values, but I need to to check the time of day to determine which Shift to return. I have been messing around with the IF ESLE and CASE but I can't find a way to tell the select statement what the time of day is.

I have a GridView with an extra checkbox column to select rows.
To select multiple rows, the user now has to click each separate checkbox, but I would like to offer the possibility to select multiple rows at once using Shift+click.
Thus the user would explicitly select the first row with a single click and the select the last row using Shift+click. And the checkboxes of the rows in between would then automatically be checked as well.
