I believe Access stores dates as real numbers representing the number of days since December 20, 1899 (or something close to that), so you probably need a conversion function. In VB, we could use CDate(X) to convert a date represented as a string to a value with date/time format. See if C# has a similar conversion function.

Ohhhh...now why don't they just say that instead of crazy errors? I don't suppose you have a resource (website, book, etc.) I can look into in case I run into this problem again for other types (i.e. stupid boolean type in another post). I will give this a try, it seems to make crazy enough sense to be right. Thanks so much! ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

I want to import a txt CSV file into a view in SQL 2000.
that can be done easily using VBA but the problem is that I want to check the validity of data e.g checking the serial no if its numeric , check the date if its in correct format...and I want to use a sql trigger for that so that each time theres an insert , before that it should chk the validity of data , etc . .
plz hlp.

Dear all;
I have a datetime field that stores data like "15/11/2006 10:12:23 AM"
how can I extract the date part only without concatenating month and day and year inside the Sql statement as i have LOTs of data to be extracted. I tried to cast to char(10) and then convert to date but it was too slow.
Thanx
Scorpion

Use the following in stored procedure,
convert(varchar,checkindate,101) as checkindate
This will extract only 15/11/2006 only.
For ur reference:
checkindate --> Field in the table.
Hope u will understand it.

I mean extracting as date not just a string !
As converting to varchar ordering as date will fail !!
If I will say "Order By convert(varchar,checkindate,101) as checkindate"
the sort order will not be correct.
Is there anything in SQL server that solves that problem ??
hope u understand it.
Thank u
Scorpion

use dateadd(day, datediff(day, 0, checkindate), 0) as checkindate to truncate the time value

Thank you indianet for your reply
but i think i will face the same problem of speed.
i didnt try it yet, but do u think it will not be slow ?
There is a function in Access that do the solution in one step like :
"Order by DateValue(CheckInDate)" and thats it !
there is nothing like that in Sql Server ?!
thanx

select convert(varchar,Reminder_date,101) as Reminder, Reminder_From, Reminder_Until, Reminder_AlarmTime, Create_dt, Update_dt from dbo.TBL_Reminder order by Reminder
It was possible to order by date.

Hello everybody,
How to build a regular expression to check that all the given words are present in a sentence in any order but all words should be present.
for example: Given words:- aaa bbb ccc
sentence:-1) rock aaa bed bbb sky ccc
2) rock bbb bed aaa sky ccc
3) rock aaa bed bbb
Matchs:- 1 and 2 should get matched in the sentence
3 is not a match
Mitesh... best of luck..

select sentence
from ( select sentence
from ( select sentence
from book
where sentence like '% aaa %'
)
where sentence like '% bbb %'
)
where sentence like '% ccc %'
;It's not a regular expression, but this is the SQL forum after all.

You are instantiating object con and then trying to open object c without instantiating it...

To do this you need to have a uniquely representing column(i.e a primary key column),and by makeing use of it u can select which ever the row u want..!(let us say primary column as id)
change your select statement to..."select * from Library where id=1"
|
|
|
|
|
u can use dataview to bind ur datagrid and can use dataview's Rowfilter property to filter the data according to condition specified by u.

use this
"select top 1 * from library"

I'm new to ASP.NET. Can anyone provide answer for my question below?
1. I have a database connection in Page 1; then after some process, it redirect to Page 2. Now my question is, if we don't close the connection (eg: MyDBConn.Close), after redirect to Page 2, will the resourse still grab in Page 1?
|

You should always close the connection after working with the database. The best practice model for ADO.NET is aquire-query-release. You should always close a connection to the database as soon as your query is complete.
Also, in ASP.NET the application is stateless. That means that when you request a page it creates a page, populates the page, streams the page to the browser, then deletes all resources used by the page.
NOTE: If a connection to a database is not closed and it goes out of scope so that the garbage collector has to deal with it you will find that the connection stays open until such time as the garbage collector cleans up your mess. That might never happen because your application may break due to lack of connections before the garbage collector gets to it.

If you want to create a project why do you want to get the complete source code from others. Try to do it of your own and in case of some troubles ask here in the relevant forum.
