You can write a script (Javascript or vbscript) that sends the mail, and then schedule that script to run every day.

How can I return a set of records that are the result of different row operations
I have a table:
Mileage
(totalMiles id ...)
How can I get a result set of:
Row diff
1 (row1-row2)
2 (row2-row3)

Assuming your ID represents sequential order, you can use correlated sub queries to solve the problem. Something like this may work for you:
SELECT
id,
ISNULL(
totalMiles - (SELECT totalMiles
FROM Mileage
WHERE id= (SELECT MIN(id)
FROM Mileage
WHERE id > BaseMiles.id)),0) AS diff
FROM Mileage BaseMiles
ORDER BY id ASC

When you are using a remote connection you have to specify the table-owner. Default this is dbo
So, what you can try is:
<br />
insert into tablename select * from [Remote System Name].[Remote Database].dbo.[TableName]<br />

1.1.2
1.1.2

You can do this in an preatty way :
In the server side of your application set the ID manually like this :
1) querry the database to return a single ID (TOP 1 if I remeber right) and sort the return descending.
Select member_id Top 1 From myTable Order By memberId DESC
2) do your stuff with the old ID an et the new intém's ID
3) add your new item
I hope you understand...because is a rough world out there...

This is probably a very simple problem but it's kicking my ass so I'll get right to it
I have a database table running of ms sql server 2000 which contains amoung other things three columns:
a DateTime which should hold only the date
a DateTime which should only hold a time
a DateTime which should also only hold a time
I need the three seperate DateTimes since the first is used in a storedprocedure to extract records based on the current day
the other two to be displayed in a datagrid as a start and stop time for an event or appointment.
now i can open enterprise manager and open the table directly and the start and stop datetime columns show the time just as i imputed it.
however as soon as my data adapter fills the dataset the datagrid displays an arbitray date (30/12/1899) but does not display the times.
is this something i have to fix on the database side with some input formating or can i control how a datagrid displays dates and times
any help would be seriously appreciated

Your problem may be because your faulty way of inserting data into the data base.
Perhaps some code example on how you insert and querry the data base wold help.

The data is already in the db i've tried entering the fields that require just the time and not the date with:
1. only the time
2. the same date as the date only field + the time
the data all looks fine in the database itself
the problem is when the dataadapter fills my dataset (which is a auto generated typed dataset) the fields for the time only items still only show the date regardless if i entered it as 1 or 2 above
here's my stored procedure to look at too if that helps
ALTER PROCEDURE dbo.GetJobs
/*
(
@parameter1 datatype = default value,
@parameter2 datatype OUTPUT
)
*/
AS SELECT Job.JobID, Job.JobTitle, Job.JobTimeStart, Job.JobTimeStop
From Job
/* SET NOCOUNT ON */
RETURN
now running this stored procedure in vs returns only the time as they were entered into the db
now if i use the preview data option in vs for the data adapter suddenly that arbitrary date shows up but the time is gone.
also when i bind it to a datagrid control the same happens
when i tried binding one of the members that should return a time to a listbox it shows the same arbitray date plus the correct time.
so that tells me my stored procedure is working and even though it isn't showing everything the dataadapter is filling the dataset with the date and time for the db members correctly
so how do i change how the datagrid displays dates and times is it something i have to do at run time and if so what

Im not sure how much this would help, but have you tried the Format command when extracting the data?
Format(date, "hh:mm") as newdate {this is off the top of my head so its probally wrong, but should get you close}
Also does this help at all?

Hey all,
I have DataRelation object between 2 tables & 2 DataGrids.
for some reasons, I delete the relation, activate an operation on the tables & then create the relation back. here is some code:
//before the operation starts:
Ds.Relations.Clear();
Ds.Tables["Cust2"].Constraints.Clear();
//after the operation
DataColumn dc1 = Ds.Tables["Cust1"].Columns["Id"];
DataColumn dc2 = Ds.Tables["Cust2"].Columns["Id"];
DataRelation Dr = New DataRelation("cust1to2", dc1, dc2);
Ds.Relations.Add(Dr);
everything is ok until now.
but when I tried to connect the tables to the datagrids:
DtGrd1.SetDataBinding(Ds, "Cust1");
DtGrd2.SetDataBinding(Ds, "Cust1.cust1to2");
I get the exception:
"Cannot have a relationship between tables in different DataSets"
does anyone know what is going on??
thanks,
RoyRose

hi all,
i have an procedure as follows:
ALTER PROCEDURE dbo.InsertNewSite
(
@param_url nchar(250),
@param_ip nchar(15),
@param_username uniqueidentifier,
@param_time datetime
)
AS
SET NOCOUNT OFF;
INSERT INTO sites
(url, ip_address, username, access_time)
VALUES (@param_url,@param_ip,@param_username,@param_time)
RETURN SELECT id FROM sites WHERE sites.url = @param_url AND sites.access_time = @param_time
and it is called from code like this:
string newSiteId = "";
lock (this.selectAllSitesNotBannedTableAdapter)
{
newSiteId = (string)this.selectAllSitesNotBannedTableAdapter.InsertNewSiteNotBanned(host, requestor, new Guid("bcadf8d7-c96d-4981-bf26-de9915ac6d49"), DateTime.Now);
}
but newSiteId always returns null?
now to explain the problem i am trying to solve with this code:
i get some data i want to store into the db, the db generates the GUID for the new row, and i then need that GUID in my application. so rather than reloading the entire datagrid, i just add the row to the grid that i just added to the db.
is it possible to get the GUID of the row just added, in one call to the db, or do i need to call it again with the select that is the return statement above ?
kind regards,
g00fy

The error message is correct. SQL Server 2000 Standard Edition will NOT run on Windows XP.

Hello again, everyone.
I'm querying a table of usernames, some of which have single quotes in them. I'm hesitant to make a stored procedure to perform a search and replace on the entire table, so I was trying to find a way to make the query tolerate the single quote using the REPLACE() method, but I haven't met with any success so far.
I've tried the following:
SELECT REPLACE(Name, ''', '%#39;') FROM Table
which it obviously doesn't like because of not having matching sets of single quotes. I've also tried replacing it with the ASCII equivalent to no avail, as well.
The particular error message I'm receiving in my ASP.Net page is:
System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near 'BRIEN'. Unclosed quotation mark before the character string ''.
The record in question returns the string O'BRIEN.
It is worth noting that the operation is not aborted when this error happens, and it does in fact return the record in the proper format. It does, however, not return any records after that one, which exist.
Any ideas? Thanks in advance for your help.
-------------------
abort, retry, fail?
