hey all, i need to find the ratio of difference in 2 datetime variables and the difference of another 2 datetime vars. I figured the best way to do it is to convert the difference in both numerator and denominator to number of minutes.
can anyone help ??
I have a column in a table that stores the number of hours a task took to do. The column TaskDuration is a datetime datatype. I need to convert the hours to something that can be summed. Does anyone how this can be done? I tried CONVERT(nvarchar(5), tblTasks.TaskDuration, 108) but of course the nvarchar(5) cannot be summed. Maybe there is a way to convert the time portion to minutes and divide it by 60, anyway if someone can offer some help I appreciate it.

I've table and data as follow,
declare @tAccount table
(
isLocked bit,
LastLockoutDate datetime,
currentDte dateTime
)
insert into @tAccount values('true','2014-04-26 16:11:25.337',getdate())
Let's say, current data as follow,
isLocked| LastLockoutDate| currentDte
12014-04-26 16:11:25.3372014-04-27 01:45:15.053
How to get different in minutes between currentDate and LastLockoutDate? Mean, currentDate - LastLockoutDate.
Hi, does anyone know a SQL statement that will take two DATETIME values and list all minutes in between them like so:
START VALUE: 5/22/2008 10:00
END VALUE: 5/22/2008 10:10
RESULT:
5/22/2008 10:00
5/22/2008 10:01
5/22/2008 10:02
5/22/2008 10:03
5/22/2008 10:04
5/22/2008 10:05
5/22/2008 10:06
5/22/2008 10:07
5/22/2008 10:08
5/22/2008 10:09
5/22/2008 10:10

In a report there are following in parameters: from date, to date, from time and to time.
I need to match these search criteria€™s against start time and stop time in assignments.
The trick: How to write SQL that meets all different cases that can arise.
The query need's to traverse through every assignment,
and see if its start and stop time is in the interval given by the user.
It should then return the minutes from the assignment that is within the interval.
I'm thinking of packaging the minute "extracting" logic in a Scalar-valued function.
It should then take the in parameters from the user, and start time and stop time from the assignment as arguments.
To consider: Crossing midnight.
E.g. the user puts in
From date: 2008-05-24
From time: 22:00:00
To date: 2008-05-26
To time: 02:00:00
Since the user wants to evaluate a time span that crosses midnight,
I'll have to look in to time spans like:
2008-05-24 22:00:00 - 2008-05-24 23:59:59
2008-05-25 00:00:00 - 2008-05-25 02:00:00
2008-05-25 22:00:00 - 2008-05-25 23:59:59
2008-05-26 00:00:00 - 2008-05-26 02:00:00
Furthermore the start- and stop time can be partially in the above interval.
E.g. an assignment starts 2008-05-24 21:46:11 and stops 2008-05-24 22:36:05.
This would then yield from the time spans above 36 minutes.
The combinations seem never-ending€¦
Dear all,
I need to ignore the hours minutes and seconds elements of a datetime field - I've got a way of doing this in my select statement but it seems to be this can't be the most efficient way!
CONVERT(datetime, CONVERT(nchar(10), db.tab.field, 101)) AS date_key
Is there a better way?
I have a datetime field that is just the date and zero for the time element. I also have a varchar field that is of the format 09:25:30
is there an easy way to add these together?
I don't mind if they get converted to integer as it will be used for comparison.
My table as data as follow,
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[table_Data]') AND type in (N'U'))
DROP TABLE [dbo].[table_Data]
GO
/****** Object: Table [dbo].[table_Data] Script Date: 04/21/2015 22:07:49 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[table_Data]') AND type in (N'U'))

Hi,
I have a job where the first step starts and checks for a condition. If its not true, I want it to reset itself and start again in 10 minutes. I'm using sp_stop_job and sp_update_jobschedule and, initially, it looks like it works. But since it's a Daily job, the 'Next Run Date' increments to the following day. Even though I'm using sp_update_jobschedule to keep the active_start_date as the same day, it still increments. I've tried updating sysjobschedules directly, but get the same results.
Any thoughts much appreciated! Here's my code:
USE msdb
--This is the part that goes in the job step
--and increments the next_run_time if the condition is true.
If
(Select count('x') from mytable (NoLock)
Where PublicationDate > getdate()) < 1
BEGIN
Declare @ActiveStartDate int
Declare @ActiveStartTime int
Select @ActiveStartDate = active_start_date from msdb.dbo.sysjobschedules (NoLock)
Where schedule_id = 61
Select @ActiveStartTime = active_start_time from msdb.dbo.sysjobschedules (NoLock)
Where schedule_id = 61
EXEC msdb.dbo.sp_stop_job @job_name = 'Owners'
Select @ActiveStartTime = @ActiveStartTime + 1000
EXEC sp_update_jobschedule @job_id = '46C074D4-908D-46AE-8B0C-A23E3AD4A4F6',
@name = 'Daily',
@active_start_date = @ActiveStartDate,
@active_start_time = @ActiveStartTime
End
I am trying to develop a sql statement that will create a recordset of the min (or max) values in x minute increments over a period of time.
e.g. over a period of 7 days, I have data that was collected in 1 minute intervals. I need to know the min (or max) value in each 10 minute interval over that same period of time.
Is there an efficient way of doing this?
Hi,

string insertQuery = "insert into date_test values(" + str + ",'" + dt + "')";
SqlCommand cmd = new SqlCommand(insertQuery, connectionToDatabase);
cmd.ExecuteNonQuery();
MessageBox.Show("saved");
}
When I run the above code, data is inserted into the table
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?

:shocked: hi,
I want to use CURRENT_TIMESTAMP - 5 minutes in a select and where clause.
I have tried using
CURRENT_TIMESTAMP - 0.004 AS [Time_-6]
But this is not a round off to a whole minute
Also tried
CURRENT_TIMESTAMP, dateadd(minute, datediff(minute, 0, CURRENT_TIMESTAMP) / 5 * 5, 0)
But this will not do wholes seconds e.g
CURRENT_TIMESTAMP = 10.03.33
CURRENT_TIMESTAMP, dateadd(minute, datediff(minute, 0, CURRENT_TIMESTAMP) / 5 * 5, 0) = 10.00.00
Can anyone help??
Hello all !
I am runing from .NET application an SQL Query
it normally return the rows in 10 seconds
but time to time the application turn 2 or 3 minutes and nearlly crash (or crash)

thank you
I have a result that comes out in number of seconds, but need to see it converted to minutes and hours and seconds. Is there a convert function that would do this?

how can i get my date minus 15 minutes in sql?
is there a dateadd function?
I have this script that runs on a LOGGING database and find hourly requests for a particular firm.
The date format is "2013-08-19 13:44:50.177"
How can I group it by every 15 mins?
select
LocalDate [date],
LocalHour [Hour],
count(*) [requests],
avg(web_request_duration) [avg response time],
min(web_request_duration) [min response time],
max(web_request_duration) [max response time]
[Code] ....
I am using below query to get the today date and time(2 hrs more than actual time)
select dateadd(HOUR, 2, getdate()) as time_added
the result of above query is "2014-10-28 13:19:09.343" but I want time up hours like shown below
"2014-10-28 13:00"
Consider a table that holds Internet browsing history for users/machines,date/timed to the minute. The object is to tag all times that are separatedby previous and subsequent times by x number of minutes or less (it couldvary, and wouldn't necessarily be a convenient round number). This willenable reporting "active time" for users (a dubious inference, but hey).There are a lot of derivative ways of seeing this information that might begood to get to. What's the fist and last of these sets of times? Whatpercentage of a given period is spanned by active times, and not? What isthe average duration of such periods? What is the average interval betweenweb hits during such periods? During other times?Blah, blah. The basic problem is my principal problem. I don't have muchexperience with cursors, but from what I understand it would be very goodindeed to spare them, given the number of records I anticipate workingwith.I'd be glad of any pointers.--Scott
View 29 Replies View Related Hi,
the SQL DB freezes and no one can access the DB for 5 or 10 minutes. Even select queries don t execute, nothing is displayed.
Until we kill the process id that s blocking in the sql activity monitor, only then the DB is released and people can work again.
What does it mean that no query executes until we kill the processes ID? what could it be?
Also, recently we created indexes and ran tuning adviser, is it possible that the creation of indexes cause the freeze of a DB? is that possible?
Thanks a lot for your help
Hi,
I have SQL 2005 full version installed a remote server and when I start my computer I can connect to the database from SQL Managment Studio and a program I'm making. After about 15 minutes I find that I cannot connect using both programs, but if I enter the servers IP address using Managment Studio I can connect (this does not happen with the program I'm making). I have to log of my computer before I can connect again.
Anyone having the same problem or how to fix it??
Thanks

Hi all, having a little problem with saving dates to sql databaseI've got the CreatedOn field in the table set to datetime type, but every time i try and run it i get an error kicked up Error "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated."I've tried researching it but not been able to find something similar.

View 4 Replies View RelatedHey :)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
Hi,
I have a column of type datetime in sqlserver 2000. Whenever I try to insert the date
'31/08/2006 23:28:59'
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?

I've the following simple code bound to a button on a Web page
string time = (string)Cache["KEY"];
if (time == null)
{
SqlConnection sqlConnection = new SqlConnection(@"Server=BIZYUSUFSQL2005;Database=Deneme;User Id=sa;Password=;");
SqlCommand command = new SqlCommand(@"select KOLON1 from dbo.CACHE", sqlConnection);
sqlConnection.Open();
SqlCacheDependency dependency = new SqlCacheDependency(command);
time = System.DateTime.Now.ToString();
Cache.Insert("KEY", time, dependency);
command.ExecuteNonQuery();
sqlConnection.Close();
}
return time;
This code has to return the time value from cache. And when a record is inserted into the CACHE table, the cache item has to be invalidated and the new time value has to be returned.
The code works properly for 2-3 minutes. But when there is no activity for 5 minutes, the cache invalidation does not work anymore.
I want to fetch all the records which are 2 minutes older
How can I do it?
The company I work for has no experience with replication, and neither have I.
Now I recieved a functional specifications document and apparently what they want is use replication to maintain a copy of a production database on the data warehouse server.
The database is 70GB, and they want to do it every 15 minutes (so their reports will contain up-to-date data).
As I said, I know nothing about replication, but to me, this sounds like madness. I fear that this will will (at least) have a negative impact on the performance of the production database.
So is it possible? Does replication have a big impact on the database or is it hardly noticable? I expect about 500 new records every 15 minutes; production database and data warehouse are on different servers; both are SQL2005.
