Calculate Elapsed Time Between Dates And Exclude A Time Span.

Dec 18, 2007

I need a formula to calculate the time (let's say in minutes) between two dates/times.
The problem is that I have to exclude the time between 06 PM and 06 AM and also exclude the time in the weekend (Saturday and Sunday).
I will use this in a couple of reports made in Reporting Services.
If anyone have an algoritm that could be modified for this and is willing to share this I would be very grateful.
Many thanks!

Group By Time Span

Feb 16, 2006

I have a database where user events are recorded quite frequently. I'd like to be able to get a count of the 'good' events that happen in each 5 second period. Unfortunately I don't know how to display and group by a time range.

Here is the query I would like to change:
SELECT count(*), clientTime
FROM dbo.V_COMBINED
WHERE (sessionId = '122b') AND (type = N'sys_goodaction') AND (paraName = 'value')
GROUP BY clientTime

It returns records like:
1 |2006-02-16 23:21:05.250
1 |2006-02-16 23:21:05.267
1 |2006-02-16 23:21:06.470

I'd like it to return records like:
5 |2006-02-16 23:21:06 - 23:21:10
3 |2006-02-16 23:21:11 - 23:21:15
4 |2006-02-16 23:21:16 - 23:21:20

Anyone know how I could do this? Is it even possible?

Thanks

How To Exact Span Of Time From A Record

Aug 23, 2012

I am not sure how to go about doing this. I have a record that has a start time of 1 am and a stop time of 9pm (same day for simplicity) and I want to know how many hours during a peek time and how many were not.

For example, the application starts and inserts into the data base the start time of 1am and then the user stops the app at 9pm. Lets say the peek hours are 1pm to 7pm. I know i can do a date diff function to get how long the app ran for but how can I get the amount of hours it ran during the peek time? I know there has to be some mathematical solution to this but it is escaping me at the moment. I want to do this over many records so a a cte or pivot table is the end solution for performance.

Summing Time Span (for Total Per Hour)

Sep 12, 2013

field prodDate puts out values as such:

8/12/2013 7:50:15
8/12/2013 7:51:03
8/12/2013 7:53:42
8/12/2013 7:54:12
8/12/2013 7:56:02
...
...
8/12/2013 14:57:57
8/12/2013 14:59:59

I'd like to get a time span sum beginning with the first prodDate entry and ending with the last.

The idea is I'll then use that to divide lbs produced, thus giving me a gauge for lb per hour.

Transact SQL :: How To Get Time Span Across Several Related Records

Nov 19, 2015

I need a boost to understand how to get started on solving this SQL Query.

TicketId Seq StatusDateTime

T10001 1 2015-05-04 15:54:00.000
T10001 2 2015-05-04 16:35:00.000
T10001 3 2015-05-04 16:42:00.000
T10001 4 2015-05-05 08:19:00.000
T10002 1 2015-05-04 15:56:00.000
T10002 2 2015-05-04 15:57:00.000

I need to find the total StatusDateTime for each TicketId
I need to find the average StatusDateTime for all TicketIDs
Ex. TicketId, "T10001", has 4 records based on the Seq column.

By using this, I should be able to find the amount of time between the first Seq and the last Seq to get a total time span for Ticket.

Expanding on this, I should be able to add up all of the Ticket's calculated time spans and divide by the number of tickets to get the average time span.

SQL Server 2012 :: Splitting Time Span Into Multiple Entries?

Jul 10, 2014

Looking for returning multiple entries from a time span. I have a date, start-time, end-time and duration. I need the start-times separated in a list. It's fine if temp tables are needed - I have that clearance.

Entry might look like:

(datetime) date: 7/10/2014

(int) start-time 820

(int) end-time 1000

(int) duration 20

The result would needed:

(datetime) 7/10/2014 08:20:00

(datetime) 7/10/2014 08:40:00

(datetime) 7/10/2014 09:00:00

(datetime) 7/10/2014 09:20:00

(datetime) 7/10/2014 09:40:00

SQL Server 2014 :: Split Time Span Into Multiple Records?

Oct 30, 2015

I have a table that includes the fields below:

ID - INT
Machine - TINYINT
StartTime - DATETIME
EndTime - DATETIME

What I am trying to do is figure out how much time is used for production per day. The problem is, there are production runs that run over midnight and possible multiple days without ending. For example, if I have the following data:

ID - 1
Machine - 2
StartTime - 2015-09-01 22:00:00.000
EndTime - 2015-09-03 22:00:00.000

So what I am looking for is taking the above record and turning it into 3 records like below:

ID Machine StartTime EndTime
1 2 2015-09-01 22:00:00.000 2015-09-01 23:59:59.999
1 2 2015-09-02 00:00:00.000 2015-09-02 23:59:59.999
1 2 2015-09-03 00:00:00.000 2015-09-03 22:00:00.000

Best Way To Retrieve Oracle Data Into SS2000 Near Real-time?

Jul 19, 2007

I have no idea where to post this kind of question, so here it is!



I have a requirement to retrieve oracle 10 data into SS2000 in as near real-time as possible (stupid users!) and join with resident SS data for on-demand reporting. (We use SS replication to populate some reporting tables from other SS2000 instances and this has spoiled the users as well as the developers! )



I would like to know if there are any clever ways of doing this, or if a plain-old DTS package running in some kind of loop is the practical answer. 1 minute delay is probably too long . . . I don't know if data can be pushed from the oracle side. Or if we need to write a Service and use it to suck and push.



Any suggestions?



thanks!

TSQL + VBA - Retrieve SQL SERVER 2000 Data Trough Excel 2003 - Time Out Error 80040e31

Sep 17, 2007

Hi guys,
When I thought everything is okay with this script, I got a new problem...
I have a VBA's script from Excel 2003 that builds sql script and retrieves data from SQL SERVER 2000.
in order to make the sql running, I need to use a multi - batch processing, to pass and execute every command line once a time.

Up to here, I am using a test case with Account number = '123456' and getting the desire results.
The code below is running okay with the test case, but when changing the account number (mark as yellow in the code) to include all the accounts (or just one other account), I am getting the following ERROR:
run - time error '-2147217871 (80040e31)' - [Microsoft] [ODBC SQL Server Driver] time out expired.

Now, if I take the same code, with the condition that generates the ERROR, and try it into SQL Server, I get the results without errors.
Thanks in advance,
Aldo.

Can Fields Span TableGroups Independantly Of Columns

Jan 31, 2006

Hi,

I'm trying to add a heading to my report using Table and TableGroups. But I don't want my group headings to line up with the detail rows. This seems like a common requirement in my mind but I can't figure out how to do it.

See made up example of a report below:




Person Name Address <-Report header




Area: A12 3BC, Newtown, Someplace <-TableGroup header




Mr Some Body 1 The Street <-Detail rows

Mrs Anne Other 2 The Street





Area: B23 4CD, Oldtown, Someplace <-TableGroup header




Mr Ran Dom 3 The Avenue <-Detail rows





So the TableGroup displays Area which is grouped by Post code, city etc.

The detail rows displays individual people and their street address.

NOTE: The Area fields do not line up with the Person fields in fact they overlap how can I do this in SSRS?

Thanks in advance for your help,

Mike G

How To Convert UTC Time (retrieved From SQL) To Local Time In Reporting Services Based On Time Zone

Aug 7, 2007



Hi all,

I have created a report in SSRS 2005 which is being viewed by users from different Time Zones.

I have a dataset which has a field of type datetime (UTC). Now I would like to display this Date according to the User Time Zone.

For example if the date is August 07, 2007 10:00 AM UTC,

then I would like to display it as August 07, 2007 03:30 PM IST if the user Time Zone is IST.


Similarly for other Time Zones it should display the time accordingly.

Is this possible in SSRS 2005?

Any pointers will be usefull...

Thanks in advance

SQL 2012 :: Accurate Sorting Data Each Time With Millions Of Records Without Time Field?

Apr 25, 2014

Sample Table

USE [Testing]
GO
/****** Object: Table [dbo].[Testing] Script Date: 4/25/2014 11:08:18 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

[Code] ....

It seems to work fine with one million records.

Each primary key is unique, but the begindate is non-unique, and i guess even if i use datetime2 and add nanoseconds, from what i have read, there is a chance that i could have a duplicate datetime since the date is imported via XML from multiple sources.

It Takes A Long Time To Insert The First Record Each Time When The Program Start

Dec 15, 2006

I am using VS2005 (VB) to develop a PPC WM5.0 Program. And I am using SQLCE 3.0. My PPC Hardware is in 400MHz.

The question is when the program try to insert the first record into sdf database after each time the program started. It takes a long time. Does anyone know why and how can I fix it?

I will load the whole database into a dataset when the program start and do all the "Insert", "Update", "Delete" in this dataset and fill it into database after each action.

        cn.Open()
        sda = New SqlCeDataAdapter(SQL, cn) 'SQL = Select * From Table
        scb = New SqlCeCommandBuilder(sda) 
        sda.Update(dataset)
        cn.Close()

I check the sda.update(), it takes about 0.08s for filling one record into database normally. But:

1. Start the PPC Program

2. Load DB into dataset

3. Create a ONE new record in dataset

4. Fill back to DB

When I take this four steps everytime, the filling time is almost 1s or even more!

Actually, 0.08s is just a normal case. Sometimes, it still takes over 1s to filling back a dataset which only inserted one record when the program is running. (Even all inserted records are exactly the same in data jsut different in the integer key)

 However, when I give up the dataset and using the following code:

            cn.Open()
            Dim cmd As New SqlCeCommand(SQL, cn) ' I have build the insert SQL before (Insert Into Table values(XXXXXXXXXXXXXXX All field)

           cmd.CommandType = CommandType.Text
            cmd.ExecuteNonQuery()
            cn.Close()
            StartTime = Environment.TickCount

 I found that it is still the same that the first inserted record takes more time, but just about 0.2s. And the normal insert time is around 0.02s. It is 4 times faster!!!

Problem With Getdate() In Transaction Takes The Insert Time Instead Of The Commit Time

Nov 12, 2007

Hi,

We need to select rows from the database that have been recently inserted/updated. We have a main primary table (COMMIT_TEST) and a second update table (COMMIT_TEST_UPDATE). The update table contains the primary key and a LAST_UPDATE field which is a datetime (to tell us when an update occurred). Triggers on the primary table are used to populate the update table.

If we insert or update the primary table in a transaction, we would expect that the datetime of the insert/update would be at the commit, however it seems that the insert/update statement is cached and getdate() is executed at the time of the cache instead of the commit. This causes problems as we select rows based on LAST_UPDATE and a commit may occur later but the earlier insert timestamp is saved to the database and we miss that update.

We would like to know if there is anyway to tell the SQL Server to not execute the function getdate() until the commit, or any other way to get the commit to create the correct timestamp.

We are using default isolation level. We have tried using getdate(), current_timestamp and even {fn Now()} with the same results. SQL Queries that reproduce the problem are provided below:


/* Different functions to get current timestamp €“ all have been tested to produce the same results */
/*
SELECT GETDATE()
GO
SELECT CURRENT_TIMESTAMP
GO
SELECT {fn Now()}
GO
*/
/* Use these statements to delete the tables to allow recreate of the tables */
/*
DROP TABLE COMMIT_TEST
DROP TABLE COMMIT_TEST_UPDATE
*/
/* Create a primary table and an UPDATE table to store the date/time when the primary table is modified */
CREATE TABLE dbo.COMMIT_TEST (PKEY int PRIMARY KEY, timestamp) /* ROW_VERSION rowversion */
GO
CREATE TABLE dbo.COMMIT_TEST_UPDATE (PKEY int PRIMARY KEY, LAST_UPDATE datetime, timestamp ) /* ROW_VERSION rowversion */
GO
/* Use these statements to delete the triggers to allow reinsert */
/*
drop trigger LOG_COMMIT_TEST_INSERT
drop trigger LOG_COMMIT_TEST_UPDATE
drop trigger LOG_COMMIT_TEST_DELETE
*/
/* Create insert, update and delete triggers */
create trigger LOG_COMMIT_TEST_INSERT on COMMIT_TEST for INSERT as
begin
declare @time datetime
select @time = getdate()

insert into COMMIT_TEST_UPDATE (PKEY,LAST_UPDATE)
select PKEY, getdate()
from inserted
end
GO
create trigger LOG_COMMIT_TEST_UPDATE on COMMIT_TEST for UPDATE as
begin
declare @time datetime
select @time = getdate()

update COMMIT_TEST_UPDATE
set LAST_UPDATE = getdate()
from COMMIT_TEST_UPDATE, deleted, inserted
where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY
end
GO
/* In our application deletes should never occur so we don€™t log when they get modified we just delete them from the UPDATE table */
create trigger LOG_COMMIT_TEST_DELETE on COMMIT_TEST for DELETE as
begin
if ( select count(*) from deleted ) > 0
begin
delete COMMIT_TEST_UPDATE
from COMMIT_TEST_UPDATE, deleted
where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY
end
end
GO
/* Delete any previous inserted record to avoid errors when inserting */
DELETE COMMIT_TEST WHERE PKEY = 1
GO
/* What is the current date/time */
SELECT GETDATE()
GO
BEGIN TRANSACTION
GO
/* Insert a record into the primary table */
INSERT COMMIT_TEST (PKEY) VALUES (1)
GO
/* Simulate additional processing within this transaction */
WAITFOR DELAY '00:00:10'
GO
/* We expect at this point that the date is written to the database (or at least we need some way for this to happen) */
COMMIT TRANSACTION
GO
/* get the current date to show us what date/time should have been committed to the database */
SELECT GETDATE()
GO
/* Select results from the table €“ we see that the timestamp is 10 seconds older than the commit, in other words it was evaluated at */
/* the insert statement, even though the row could not be read with a SELECT as it was uncommitted */
SELECT * FROM COMMIT_TEST
GO
SELECT * FROM COMMIT_TEST_UPDATE


Any help would be appreciated, we understand we could make changes to the application/database to approximate what we need, but all the solutions have identified suffer from possible performance issues, or could still lead to missing deals (assuming the commit time is larger than some artifical time window).

Regards,

Mark

I need to take a temporary table that has various times stored in a text field (4:30 pm, 11:00 am, 5:30 pm, etc.), convert it to miltary time then cast it as an integer with an update statement kind of like:

Update myTable set MovieTime = REPLACE(CONVERT(CHAR(5),GETDATE(),108), ':', '')

how this can be done while my temp table is in session?

SQL Server 2008 :: Displaying Transaction Time Punch Data In A Time Card Form?

Oct 7, 2015

I have a table called employee_punch_record that we use to store employee time clock punches.

The columns are:

employeeid,
punch_timestamp,
punch_type (In / Out),
closed (bit used as status for open or closed pay periods),
ident

Here are some examples of a record:

bkingery62015-10-06 16:59:04.000In0
bkingery72015-10-06 16:59:09.000Out0
bkingery82015-10-06 16:59:13.000In0
bkingery92015-10-06 18:22:44.000Out0
bkingery102015-10-06 18:22:46.000In0
bkingery112015-10-06 18:22:48.000Out0
bkingery122015-10-06 18:22:51.000In0
tfeller52015-10-05 17:00:05.000In0

We are using SQL Server 2008 as our database and use Access as a GUI. I am looking to create a form in Access where employees can access their time card and request changes from management. I want to use the format from the attached screen shot for the form. I pretty much know how to do it all, the only point of complication is trying to figure out the easiest way to get the transaction punch record data on employee_punch_record into a format where I can easily populate the form in the horizontal format you see in the screen shot.

I am not super strong in SQL, but figure I can do it using a formatting table of some sort. quick and easy way to move transaction records into a more horizontally oriented record?

A Time Series Prediction Was Requested With A Start Time Further In The Past Than The Internal Models Of The Mining Model

Feb 19, 2008

Hi all,

I have a very simple time series model which processing works fine without any problem. However when I run the following query

SELECT

[TimeSeries].[PriceChange],

[TimeSeries].[Symbol],

PredictTimeSeries(PriceChange, -3, 2)

From

[TimeSeries]

WHERE

[TimeSeries].[Symbol] = 'x'


I get the following error:

TITLE: Microsoft SQL Server 2005 Analysis Services
------------------------------
Error (Data mining): A time series prediction was requested with a start time further in the past than the internal models of the mining model, TimeSeries, specified in the HISTORIC_MODEL_GAP and HISTORIC_MODEL_COUNT parameters can process.

The following is the excerpt of the minding model script related to the two parameters:


<AlgorithmParameters>

<AlgorithmParameter>

<Name>MISSING_VALUE_SUBSTITUTION</Name>

<Value xsi:type="xsdtring">Previous</Value>

</AlgorithmParameter>

<AlgorithmParameter>

<Name>HISTORIC_MODEL_GAP</Name>

<Value xsi:type="xsd:int">1</Value>

</AlgorithmParameter>

<AlgorithmParameter>

<Name>HISTORIC_MODEL_COUNT</Name>

<Value xsi:type="xsd:int">10</Value>

</AlgorithmParameter>

</AlgorithmParameters>


These HISTORIC_MODEL_GAP (1) and HISTORIC_MODEL_COUNT (10) should accommodate PredictTimeSeries(PriceChange, -3, 2). Could anyone shed some light on this?

Reporting Services :: SSRS Loses Ability To Delegate User Credentials To Database Time To Time?

Apr 30, 2015

we have problems with our SQL Reporting Service 2012 (SSRS) server . We have setup Kerberos delegation between SSRS and the database server (SQL Server Always-on cluster) so users are authenticated down to the database. The issue occurs from time to time that SSRS loses the ability to delegate the user credentials to the database. At this point in time the Report Server logs contain rejected database connections because of ANONYMOUS logon. After restarting SSRS the problem is gone.
