Compare DateTime Values

Feb 2, 2006

guys this is kind of a biggie for me.
i've only used sql server to compare the Date Portion of date(s), not the whole string (mm/dd/yyyy hh:mi).
i have a table called Time_Check which has two fields with timestamps,
"TimeLastRun & TimeNextRun". i was trying to compare the Current TimeStamp that i pass from a vb.net form to a stored procedure and compare that DateTime to the TimeNextRun. I'd like to then Update the two Time Columns if rows are found. Should i maybe be using the DateDif Func if i know ahead of time how much time should be elapsed(say five minutes)?
Any Code help is appreciated

Create Procedure dbo.My_Time_Check
@myDate smalldatetime
as
select alertnumber,alertname,TimeLastRun,TimeNextRun
from time_check
where timeNextRun >= @myDate
--would like to update these two columns if rows are found

thanks again
this forum is the best

How Can I Compare Datetime In A Query???

Jul 4, 2006

I have a table with the following columns

company_Id employee_id logon_time_id logoff_time start_valid_period end_valid_period

Employee's working time should only be counted if it is between start_valid_period and end_valid_period

So, if I have for employee1 from company1

logon_time_id = 04/07/2006 11:00
loggoff_time = 04/07/2006 12:20
start_valid_period = 04/07/2006 12:10
end_valid_period = 04/07/2006 12:30

I should consider 04/07/2006 12:10 as the initial datetime, 04/07/2006 12:20 as the final datetime, and count only 10min of work to him. In code:

if(logon_time_id < start_valid_period) initialDatetime = start_valid_period else initialDatetime = logon_time_id

if(logoff_time < end_valid_period) finalDatetime = logoff_time else finalDatetime = end_valid_period

Is there anyway I can do this in a query, without using a stored procedure with "ifs" and everything else?

Thank you!

DATETIME Compare Issue

Aug 2, 2007

I am trying to do a select where one set of date/time columns are greater than another. My date is stored in one column while the time is stored in another. Only the date portion of the date column is valid and only the time portion of the time column is valid.
Example my date column value is 8/1/2007 01:01:01 AM and my time column value is 1/1/2007 07:23:49 AM which in my system means the last update time was 8/1/2007 07:23:49 AM.

My select statment looks like this.

SELECT *
FROM CHANGE
WHERE
CONVERT(DATETIME( DATE_LAST_ALTERED, TIME_LAST_ALTERED)) < CONVERT(DATETIME(DATE_APPROVED,TIME_APPROVED))

I get an incorrect syntax near 'DATE_LAST_ALTERED'.

Am I totaly missing the point of DATETIME?

Conditional Split - Compare DATETIME With Constant

Sep 26, 2007



Hi,

I have to compare a DATETIME Field with '1/1/1900 12:00:00 AM". Which is default DATE TIME Value in SQL Server.

I did compare like
TRADEAGREEMENTFROMDATE != (DT_DBTIMESTAMP)(DATEPART("mm",(DT_DBTIMESTAMP)"1/1/1900 12:00:00 AM"))

but (DT_DBTIMESTAMP)(DATEPART("mm",(DT_DBTIMESTAMP)"1/1/1900 12:00:00 AM")) returns "12/31/1800 12:00:00:AM"

Thanks,

Jul 9, 2007

Hi,
I'm inserting a datetime values into sql server 2000 from c#

SQL server table details
Table nameate_test
columnname datatype
No int
date_t DateTime

C# coding
SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI");
connectionToDatabase.Open();
DataTable dt1 = new DataTable();
dt1.Columns.Add("no",typeof(System.Int16));
dt1.Columns.Add("date_t", typeof(System.DateTime));
DataRow dr = dt1.NewRow();
dr["no"] = 1;
dr["date_t"] = DateTime.Now;
dt1.Rows.Add(dr);
for(int i=0;i<dt1.Rows.Count;i++)

The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column.
Is there any conversion needed for millisecond values?

SQL Query: Finding Records Between Datetime Inside Datetime

Mar 17, 2007

Hey :)I'm facing a lot of troubles trying to create a new pause/break-system. Right now i'm building up the query that counts how many records that is inside 2 fields. Let me first show you my table:
ID (int)     |    stamp_start (Type: DateTime)        |      stamp_end (Type: DateTime)           |      Username (varchar)0             |      17-03-07 12:00:00                      |            17-03-07 12:30:00                     |     Hovgaard
The client will enter a start time and a end time and this query should then count how many records that are inside this periode of time.
 Example: The client enter starttime: 12:05 and endtime: 12:35.The query shall then return 1 record found. The same thing if the user enters 12:20 and 12:50.My current query looks like this:SELECT COUNT(ID) AS Expr1 FROM table WHERE (start_stamp <= @pausetime_start) AND (end_stamp >= @pausetime_end)But this will only count if I enter the exact same times as the one inside the table.Any ideas how I can figure this out?Thanks for your time so far :)/Jonas Hovgaard - Denmark

Datetime Data Type Resulted In An Out-of-range Datetime Value. Please Help

Hi,

 I get the error "...datetime data type resulted in an out-of-range datetime value"
I've looked everywhere and I can't solve the problem. Please note, I first got this error from an asp.net page and in order to ensure that it wasn't some problem with culture settings I decided to run the query straight in Sql Query Anaylser. The results were the same. What else could it be?

Comparing A Real Datetime To A 'constructed' Datetime

Jun 15, 2004

I have the following SQL:

select convert(datetime,'04-20-' + right(term,4)) as dt,
'Deposit' as type, a.* from
dbo.status_view a

where right(term,4) always returns a string which constitutes a 4 digit year eg '1999','2004',etc.

The SQL above returns

2004-04-20 00:00:00.000 Deposit ...

Which makes me think that it is able to successfully construct the datetime object inline. But then when I try and do:

select * from
(
select convert(datetime,'04-20-' + right(term,4)) as dt,
'Deposit' as type, a.* from
dbo.status_view a
) where dt >= a.submit_date

I get the following error:

Syntax error converting datetime from character string.

Given that it executes the innermost SQL just fine and seems to convert the string to a datetime object, I don't see why subsequently trying to USE that datetime object for something (in this case comparison with submit_date which is a datetime in the table a) should screw it up. Help!!! Thanks...

How To Convert Datetime From Varchar To Datetime

How do i convert a varchar field into the datetime data type? the reason i need this lies in the requirement that in the earlier data base the column that is hlding the date value is having the data type as varchar. and in the new design the column data type is datetime. i am using sql scripts for the data migration from the older design to the newer and got stuck with this datetime convertion issue. do let me know the best possible solution.

following are the sample data that is theer in the older table for the date.


12/12/2003
1/13/2007
01132004
1-1-2004
1.2.2001



there is no uniformity of the data that is stored currently.

DateTime -&> MSSQL -&> DateTime

Jun 9, 2008

Hi All,This is only my second day using C#/asp.net and English isn't my native language so I'll apologise in advance if this question doesn't make sense and/or is stupid . I'm trying to make a little event planner which was going well until I hit a small problem, the user needs to enter the event name and choose a date/time from dropdowns, this bit works okay... however I'm having difficulties with storing the date/time, at the moment I'm making a DateTime object and filling out the year/month/day/hour/minute selected on the form and adding that to the database field (which is a datetime field type).Problem is, I'm using the date format DD/MM/YYYY HH:MM:SS but the database stores it as MM/DD/YYYY HH:MM:SS so if I wanted to do things like:
select * from tbl where date > DateTime.Now - it isn't going to work because the month is switched with the day in the DB-versions.
Just to try and give another example, if I'm not being very clear, if I print DateTime.Now.ToString() it will display 10/06/2008 02:50:48 however if I put it into the database and pull it back out cast to a DateTime Object and then display that object via ToString() it'll be 06/10/2008 02:50:48
Any suggestions on what to do would be appreciated, usually in cases like this I'd just use the unix timestamp, but since C#/ASP.NET doesn't support that natively I was hoping there was an easier/native alternative. Also I don't have access to the server configuration so changing the localization of mssql isn't an option unfortunately.Thanks in advance!
