In .NET all you have to do is open an OracleDataReader from an OracleCommand and then call GetDateTime. It works for me. .NET should handle all the type conversion issues: the OracleDataReader "knows" how to convert SQL types to .NET types so that I don't have to. It's called encapsulation. Or maybe abstraction, I can never remember the difference between those two.

Thanks a lot for your input. The problem has dissolved somehow - I use to shutdown the server and the client in the evening and start them again next morning, and now the problem cannot be reproduced. Maybe there was some inconsistent state in the Oracle database, during development things can go wrong and Oracle likes to punish you horribly for the smallest misdeeds....

Hi All,
I am struggeling finding an effectient way to find a distance between a Point that intersects a polygon and the border of that polygon. I was able to use the STDistance comparing the point to every point that made up the polygon but that is taking a lot of time. Using SPatial indexe wasn't much helpful because the STDistance is not part of any constraint and even when I did put the constraint, the index didnt help much.
I appreciate any feedback.
Thanks

Looks like you might have to write some code. For the basics, google "distance point line". Once you have that, you just need to find the minimum of the distances to the edges of the polygon. Calculation should be O(n) for an n-gon.

Thats what I am doing but its freakin slow. After a lot of research I found an excelent blog describing an efficient way to do this:

hi iam using sql server 2000
my table is branch
BranchName nvarchar(50),
ContractNo nvarchar(50),
Email nvarchar(50),
StartDate datetime,
EndDate datetime,
ContractReminder int,(5days,10days,15days)
remindertype int(1month,3month,6month,annual)
i have to send the email to the user before enddate and check the ContractReminder if it is for 5 days then send before 5days ,if it is for 10days then before 10 days and also check the remindertype if it is for one then before one month before contractreminder ie 5 days or 10 days i have to send the mail like this for three months, 6 months , and for annually
how to write this querry can you give an idea which helps me

It looks like you need a job to run every day that by using two datediff criteria using an OR between them.
This could then get the list that is sent to.
Sorry I cannot be more specific as I am installing SQL 2008 R2 on my system, so I cannot try an example.
See BOL for Datediff and you will use days I would suggest using days for the month also as that would prevent the letter from being sent every day of the month.
SELECT * FROM branch
WHERE DATEDIFF('dd', GETDATE(), EndDate) = ContractReminder
OR DATEDIFF ('dd', GETDATE(), EndDate) = ReminderType * 30 NOT TESTED
Good Luck,

hi iam using this querry
SELECT BranchName,ContractNo, Email,StartDate,EndDate, ContractReminder,
DATEADD(mm,ReminderType,StartDate)-ContractReminder as newd
it works fine for the first time only for 1 month, 3months,or 6months,
suppose the starttime is 2010-01-01 and enddate is 2010-12-31
the querry will works fine for only first time for 1st month, or 3rd month, or 6th month
but i want the querry to check upto enddate repeatedly ie for a year i want the querry to be executed 12 times, if it is for 3 months the querry should be executed for 4 times in a year
how can i get this querry please give suggesstion

A suggestion would be
SELECT BranchName, ContractNo, Email, StartDate, EndDate,
CASE
-- notice that the 101 is my favorite see BOL Convert for list of others
WHEN CONVERT(VARCHAR, DATEADD(day, ContractReminder, GETDATE()), 101) > EndDate
THEN 'Less than ' + CAST(ContractReminder as VARCHAR) + ' days left'
WHEN CONVERT(VARCHAR, DATEADD(month, remindertype, GETDATE()), 101) > EndDate
THEN 'Less than ' + remindertype + ' months left'
END AS MyFlag
INTO #RList
WHERE CONVERT(VARCHAR, DATEADD(day, ContractReminder, GETDATE()), 101) > EndDate
OR CONVERT(VARCHAR, DATEADD(month, remindertype, GETDATE()), 101) > EndDate
|
|
|
|

try something like this.
*assumption that all contract end dates are in the future
select branchname, contractno, email, startdate, enddate, contractreminder, remindertype
from branch
where convert(varchar(20), enddate,112) = convert(varchar920), dateadd(dd, contractreminder, current_timestamp),112)
-- this will then removes the issues of the times in the datetime column

I have a table that has a PK index on a VARCHAR(10) field. I insert 'A'. Next I try to insert 'A '. The insert isn't allowed because of the index. How can I make it so that 'A ' is allowed to be inserted?
Thank you in advance.
EDIT: The first is just A. The second was A[space].

yeah, primary keys are a nuissance; they have a habit of wanting to be unique. Remove the old 'A' before you insert a new 'A'.

If you genuinely need to add a second 'A' (rather than just trying to find out what happens if you do), then the chances are that the design of your database is less than optimal.

yes, there is an issue with trailing spaces; here[^] is one discussion of that topic. I would avoid such situations by trimming all text before it goes into the database, otherwise you'll get trouble sooner or later, as you can hardly see the spaces at all and they may cause your selections to behave inconsistently.

Too slow Pattyn! 
I still think it's in the wrong place. Shouldn't it be a reply to the OPs' second post?

OK. You get away with it.............this time.
