I previously posted about a problem where I added a non-NULL DEFAULT 0 bit column to a table with 80 million records. It was taking a LONG time and we needed that database up fast. It ended up taking a total of 17 hours.
Now my coworker added the same non-NULL DEFAULT 0 bit column to another table on another important server. But this table has more like 400 million rows. It's been running for 100+ hours and is still going. We were hoping it would scale linearly (5*80 million records would hopefully take 5*17 hours) but that isn't happening. I have no idea how much longer it will take. I really need this to be done. I'm tempted to cancel but that will incur a potentially massive rollback, right? Any guestimate on how large that would be?
i'm trying to capture data for every hour and would like to display the hours of the day in a column.
select case when (datepart(hh,calldate) between 0 and 7AM then 1 else 0 end as [12-7AM], case when (datepart(hh,calldate) = 8 then 1 else 0 end as [8AM] from table1 where cast(calldate as date) = cast(calldate as date)
I have data coming from a telephony system that keeps track of when anemployee makes a phone call to conduct a survey and which project numberis being billed for the time the employee spends on that phone call in aMS SQL Server 2000 database (which I don't own).The data is being returned to me in a view (see DDL for w_HR_Call_Logbelow). I link to this view in MS access through ODBC to create alinked table. I have my own view in Access that converts the integernumbers for start and end date to Date/Time and inserts some otherinformation i need.This data is eventually going to be compared with data from someelectronic timesheets for purposes of comparing entered hours vs hoursactually spent on the telephone, and the people that will be viewing thedata need the total time on the telephone as wall as that total brokendown by day/evening and weekend. Getting weekend durations is easyenough (see SQL for qryTelephonyData below), but I was wondering ifanyone knew of efficient set-based methods for doing a day/eveningbreakdown of some duration given a start date and end date (with theday/evening boundary being 17:59:59)? My impression is that to do thiscorrectly (i.e., handle employees working in different time zones,adjusting for DST, and figuring out what the boundary is for switchingfrom evening back to day) will require procedural code (probably inVisual Basic or VBA).However, if there are set-based algorithms that can accomplish it inSQL, I'd like to explore those, as well. Can anyone give any pointers?Thanks.--DDL for view in MS SQL 2000 database:CREATE VIEW dbo.w_HR_Call_LogASSELECT TOP 100 PERCENT dbo.TRCUsers.WinsID, dbo.users.username ASInitials, dbo.billing.startdate, dbo.billing.startdate +dbo.billing.duration AS EndDate,dbo.billing.duration, dbo.projects.name ASPrjName, dbo.w_GetCallTrackProject6ID(dbo.projects.descript ion) AS ProjID6,dbo.w_GetCallTrackProject10ID(dbo.projects.descrip tion) AS ProjID10,dbo.billing.interactionidFROM dbo.projects INNER JOINdbo.projectsphone INNER JOINdbo.users INNER JOINdbo.TRCUsers ON dbo.users.userid =dbo.TRCUsers.UserID INNER JOINdbo.billing ON dbo.users.userid =dbo.billing.userid ON dbo.projectsphone.projectid =dbo.billing.projectid ONdbo.projects.projectid = dbo.projectsphone.projectidWHERE (dbo.billing.userid 0)ORDER BY dbo.billing.startdateI don't have acess to the tables, but the fields in the view comethrough as the following data types:WinsID - varchar(10)Initials - varchar(30)startdate - long integer (seconds since 1970-01-01 00:00:00)enddate - long integer (seconds since 1970-01-01 00:00:00)duration - long integer (enddate - startdate)ProjID10 - varchar(15)interactionid - varchar(255) (the identifier for this phone call)MS Access SQL statement for qryTelephonyData (based on the view,w_HR_Call_Log):SELECT dbo_w_HR_Call_Log.WinsID, dbo_w_HR_Call_Log.ProjID10,FORMAT(CDATE(DATEADD('s',startdate-(5*60*60),'01-01-197000:00:00')),"yyyy-mm-dd") AS HoursDate,CDATE(DATEADD('s',startdate-(5*60*60),'01-01-1970 00:00:00')) ASStartDT,CDATE(DATEADD('s',enddate-(5*60*60),'01-01-1970 00:00:00')) AS EndDT,DatePart('w',[StartDT]) AS StartDTDayOfWeek, Duration,IIf(StartDTDayOfWeek=1 Or StartDTDayOfWeek=7,Duration,0) ASWeekendSeconds,FROM dbo_w_HR_Call_LogWHERE WinsID<>'0'
We have a few Servers that have space issues that need full DB Backups every day. As a result, we have to carefully watch how many DB Backup files we keep on the Server. On the Maintenance Plan, if I set the 'Delete files older than:' to '1' 'Day', will this delete anything over 24 hours old? What I have noticed, is that it tends to delete on Tuesday anything that was created on Sunday, but not Monday. Therefore, I am assuming that instead of '1 Day' being 24 hours, it is anything less than 47 hours and 59 minutes...
Is my assumption correct or do I need to look at something else. Thanks!

I am wanting a similar solution, I need to convert an "int" to a time format, when I use this where ">= DATEADD(minute, - 720, GETDATE())" for the last_run_time I get this error:

I have a job that runs between the hours of 10 PM and 9 AM. It launches a controller stored procedure that will call other stored procedure until the entire process is done.I would like the controlling stored procedure to only call the steps between the hours of 10PM and 9AM also.. So at 8:59 AM it will start the next step, but at 9:00 AM it will exit.
I use SQL 2K with an Access 2000 project as front end. I have four date fields in a table. The first one should contain a date (eg 20th of February), the second one a starting hour (eg 8:00h), the third one the finishing hour (eg 10:00h) and the fourth should calculate the difference between the second and third column. So I created four datetime fields. Storing a date in the first column is no problem, but storing only hours doesn't seem to do what I want. When I enter 8:00 from within the Access, it is stored 1/1/1900 8:00 in SQL Server. How can I make sure that the hours are saved with the date of the second column, so either as 8:00 without further information or as eg 20-2-2004 8:00?
I am querying a database that has hours worked listed by pay rate. I want to return sum of hours per pay rates I have been given but hours are stored in multiple columns. So If I run the below query for one worker it returns.

Is there a function in SQL Server 2005 that can add GMT deviation hours to the existing date. I have a data field with the GMT_Deviation_Hours listed in numeric format e.g. -1, 12 etc. I have another date field to whom i wish to deviate the datetime according to the GMT_Deviation hours.
I have to compare 1 hour between two days , example:
I have this datetime value (BitacoraProcesoUsuario.FechaInicioProceso) in 108 format : 23:35:22
and I make this query:
Select TOP 100 * from BitacoraProcesoUsuario INNER JOIN Turno ON convert(varchar,BitacoraProcesoUsuario.FechaInicioProceso,108) > = '24:00:00' AND convert(varchar,BitacoraProcesoUsuario.FechaInicioProceso,108) <= '06:29:00'
and returns nothing........ this because 23:35:22 is gtreater than 06:29:00' value, my question is how can I compare this hours in this format.
I would like to know the best method or the simplest method to do the following. Take a datetime value and subtract a given number of hours. I am taking a UTC time and subtracting a given number or hours in a query. I seem to be getting mixed results.
What is the best data type to use when tracking hours, for example; 2.30 < this is stored in DB (two hours and thirty minutes) 5.15 < this is stored in DB (5 hours and fifteen minutes)
MS SQLJust to confirm, I need to store the number of hours a user has spent doing something, am I correct using the smalldatetime field for the MS SQL database?I will eventually need to be able to calculate totals using SQL Reporting Services so it's important that the hours add up correctly (to 60 minutes, not 100).ASP.NETI'm trying to find the correct sort of formatting to use? Short time stores the time as 9:50AM, which isn't what i'm after.I need to store the hours as in 1 hour, or 01:00:00 (1 hour, 0 minutes, 0 seconds) or just 01:00 for 1 hour. I do need minutes but seconds are not required.I can't find the right formatting for this, would Long time be more suited?
I have a SQL 7.0 backend for a new DB of mine. This is the first time I have developed a SQL backend from scratch, so the problem may be my design. The problem may lie with my Access frontend (I have tried both 97 and 2k), but I am inclined to think not considering the behavior. On only one table (the master table no less), I cannot add records during business hours. I can add records to other tables and edit records on this table though. This troublesome table has a field indexed as unique that is not the PK (don't know if that has any bearing, but it is the only table in this DB that has that property). The adding records problem appears to be network traffic related because sometimes records can be added at lunchtime and definitely after hours. I currently only have 3 connected users. I had these problems with only one connected user, so the DB itself is not being strained by traffic. I often have more traffic on the DB after hours to avoid the problems. I have worked on the connection and network traffic angle for awhile, when I stumbled upon the bizarre part. If I add a record via a stored procedure and run this SP on the SQL query analyzer on the server (no network is involved) it is still slow to add the record (30 minutes or more). Needless to say this would equate to an failure on the front end. The same query will run in 0-3 seconds after hours! Does anyone have any clue how this could happen? I am stumped. I do have a budget for a consultant if I need one, but I need to find someone who has a chance to fix this problem. If you don't know the answer but can refer someone in the DFW area, I am in your debt.
I am trying to calculate business hours that an order that is open. The rules are 8am-5pm. For instance the first row, the clock would stop at 17:00, and pick up again at 8am and add on to total business hours. If the order was created after business hours, and the endstamp was before business hours, this would be 0. If created after 5pm friday, and the endstamp was before 8am monday, this would be 0. In the second set of timestamps I have here the order was recieved at 14:39 but took until the following day at 14:49 to be ordered. I imagine I have to use datepart and datediff for this, but other than that I am not sure on how to do it. Any help would really be appreciated!

I'd like a function that returns the number of hours in a specific month (or the number of days which I could then multiply by 24). The function would have to consider leap years for February.
This code displays records by the the month they where recorded and displays the months as names (January...) How can I do the Same for Days (Mon, Tues) and Hours (9.00,10.00)
Select DATENAME(mm,dDate) as Month, count(iStatID) as Total_Po from ListingStats Group by DATENAME(mm,dDate) Order by DATENAME(mm,dDate)
I am attempting to compute Service Levels for an interaction based upon business hours. For example, an email arrives at 4pm and is handled the following day at 10am. Call Center Hours are 8-5.
Essentially I have a number of different alternatives, and have found some potential solutions, including:
www.dbforums.com/arch/7/2003/9/914261
However, my situation has a couple of additional twists to the standard 8hrs of business M-F. The call center is open different hours depending upon the day of the week. For example, 8-5 M, 10-7 T, 8-5 W Th F, 10-2 Sat, 10-12 Sun
Additionally, I would like to remove Holiday's from the calculation for service level as well.
I have explored a number of different table DTD's, but none seem to be a perfect fit for determining the number of "open" hours between when an interaction arrived, and when it was handled.
The DTD I have for the Holiday table is as follows:
CREATE Table Holidays (HolidayDate DateTime) GO Insert Into Holidays (HolidayDate) Values ('12-25-2004')
Please let me know what you feel would be the DTD for storing the business hours and also the query for extracting the number of Open hours between two dates
I have two field and I need to find the sum I guess of them. One is called the clm_dout (process date) and the other one is clm_rcvd (received Date). These are both date and time fields and it looks like this 2006-03-17 00:00:00.000. I need to create a formula that wiil i guess give me the difference and create it into hour and minutes because I an trying to create a turn around report. this is what I had...
TimeValue({clm_doubt}-{clm_rcvd})
This is not working for me. Can someone give me a suggestion please.
I went to View Synchronization status and see that the sychronization has been running for two hours already. Is that normal? I thought it would just find the one change I made and update that one change?
