Calculate Time Lapse

Apr 5, 2006

Can anyone help with the following Transact SQL question? Thanks. I
need a store procedure to return the the result recordset which will be
execute from a web page. The database has tables, A and B. For each A
record, there are many related B records. In the B table there is a
timestamp field which tracks the change of A record. For example, A1
has B like the followings:

ID TimeStamp Chg Code Descption
== ========= ======= ========
A1 1138375875 E null //end of the event
A1 1138025002 S resume
A1 1137092615 S don't care
A1 1137092570 S stop
A1 1137092256 I null //start of the
event

I need to generate all records in table A and total elapse time for
each record, but B with Chg Code 'S' that has "don't cacre" to be
deducted from the total time, so that the result will be like this:

ID Name TotalTime
(seconds)
== ==== =======
A1 xyz 351187

Decent Way To Calculate Lapse?

Apr 2, 2008

I’m checking to see if anyone might know of a good way to accomplish what I’m trying to do. I have Customers and Orders. A customer might be the one who ordered a product or whom the product was sold to (yes they can be different. Think of a person ordering for a company). Now my requirement is to find the customers that Lapsed. A Lapsed customer is defined as a customer that has not made a purchase within 2-times their average time period between purchases. For example, if a customers purchase frequency averages 180 days. Then if they have not made a purchase within 360 days of today (2 x 180), then they are lapsed. Hopefully, that makes sense. If you need more information, just ask.

Here is some sample data (Just ignore customer ID 6):DECLARE @Customer TABLE
(
CustomerID INT NOT NULL PRIMARY KEY
)

DECLARE @Order TABLE
(
OrderID INT NOT NULL PRIMARY KEY,
OrderDateNumber INT NOT NULL,
OrderedByCustomerID INT NOT NULL,
SoldToCustomerID INT NOT NULL
)

INSERT @Customer
SELECT 1
UNION ALL SELECT 2
UNION ALL SELECT 3
UNION ALL SELECT 4
UNION ALL SELECT 5

INSERT @Order
SELECT 1, 20070702, 2, 6
UNION ALL SELECT 2, 20040805, 3, 3
UNION ALL SELECT 3, 20071031, 2, 6

Determine Time Lapse Between 2 Rows

Jun 9, 2007

I have a table of machine data that captures fault codes, time machine stopped and time machine started. I can easily calculate the downtime, but how do i take the last start time and subtract it from the next stop time (1 row from the next row) to get an up time. I need it to group by short date and fault as I intend to use Excel as a reporting tool and pulling in all data will not fit. What is the most efficient way?
Thanks,

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!

T-SQL (SS2K8) :: Calculate Time In Minutes

Oct 8, 2014

I am having below schema:

CREATE TABLE #Attendance(
[ID] [int] IDENTITY(1,1) NOT NULL,
[StudentID] [int] NOT NULL,
[ClassID] [int] NOT NULL,
[DateAdded] [datetime] default getdate() NOT NULL
) ON [PRIMARY]

insert into #Attendance(StudentID,ClassID,DateAdded) values(1,1,'2014-10-07 10:38:02.900')

[Code] ....

DateAdded column in first table is nothing but in and out time.

Now I want to prepare a query where I want to consider MIN DateAdded and max DateAdded and calculate the duration of student present in the class.

Validations i need to consider are:

If class is starting at 10am then student can come at 9:50am, i.e. Dateadded column should consider as student present in that class if value is less that 10 minutes of StartTime from #ClassAttendance table. Class End time i want to calculate depending upon ClassMinutes from #ClassAttendance

Also DateAdded column should be 10 minutes plus compared to calculated endtime. If its more than that consider lower DateAdded time.

And by using this thingIi want to calculate total number of minutes student present in the class and number of minutes absent.

If there is only one DateAdded for class then consider as a absent student.

Transact SQL :: How To Calculate Estimated Completion Time Of A Job

Nov 4, 2015

How to calculate estimated completion time of a job and what is the variance/difference in time based on previous job history. Looking for tsql query which can accomplish this.For example)...Daily a job is taking 10 mins to complete. However, today due to some reason, the job is running over an hour and still running. It could be a blocking issue or some performance issue on the server due to which the job is still running.

In such cases, using a tsql query or a stored proc which monitor these jobs every 3 mins (Configurable value), so every 3 mins , query has to check, if they are any jobs which are taking more time than its usual completion time/avg completion time in that case shoot an email using dbmail functionality i.e. sp_Senddbmail .. From there, DBA can dig further using waits or sql trace etc...

SQL 2012 :: Calculate Time Difference For Consecutive Rows?

Jul 2, 2015

I have a table like this.

CREATE TABLE Table1
([S_ID] varchar(7), [S_ACTV_CODE] varchar(4), [S_USER] varchar(5), [S_DATETIME] varchar(19), [S_ACT_IND] int)
;
INSERT INTO Table1
([S_ID], [S_ACTV_CODE], [S_USER], [S_DATETIME], [S_ACT_IND])
VALUES
('AAA-111', NULL, 'USER1', '2015-06-15 00:21:06', 0),
('AAA-111', '2', 'USER1', '2015-06-15 00:21:07', 0),

[code]....

Basically I want to calculate the time spent by S_Users on a particular S_ACTV_CODE:

- S_ACTV_CODE_PREV means the previous active records.

- S_START_TIME is the time of S_DATETIME when a S_ACTV_CODE starts

- S_END_TIME is the time before a S_ACTV_CODE changes to another S_ACTV_CODE

- For the first record, S_ACTV_CODE is null, so there is no S_ACTV_CODE_PREV, so S_ACTV_CODE_PREV is NULL

- For the second record S_ACTV_CODE has some value, but S_ACTV_CODE_PREV is NULL for first record. So second record S_ACTV_CODE_PREV is also NULL

- For the last record (means S_ACTV_IND = 1), the user is currently working on it and S_ACTV_CODE is not changed. So S_END_TIME is a open time and we want to keep it as NULL

So the result should be as below:

S_ID S_ACTV_CODE_PREV S_ACTV_CODE_CURR S_USER S_START_TIME
S_END_TIME TIME_SPENT (in Sec)
AAA-111 NULL NULL USER1 2015-06-15 00:21:06
2015-06-15 00:21:07 1
AAA-111 NULL 2 USER1 2015-06-15 00:21:07
2015-06-17 03:20:33 183566
AAA-111 2 4 USER2 2015-06-17 03:20:33

[code]....

SQL Server 2012 :: Calculate Elapsed Time And Display As Row In Results

Jun 19, 2015

I am trying to calculate the time difference between the value in the row and the min value in the table. So say the min value in the table is 2014-05-29 14:44:17.713. (This is the start time of the test.) Now say the test ends at 2014-05-29 17:10:17.010. There are many rows recorded during that start and end time, for each row created a time stamp is created. I am trying to calculate the elapsed time and have it as a row in the results.

min(timestamp) - timestamp(value in row) = elapsed time for that test
where Channel = '273'

Here is the table DDL

CREATE DATABASE SpecTest;
USE SpecTest
GO

CREATE TABLE [dbo].[Spec1](
[Spec1ID] [int] IDENTITY(1,1) NOT NULL,
[Channel] [int] NOT NULL,

[Code] ....

Here is some dummy data to use

INSERT INTO Spec1 (Channel, Timestamp, Lambda, Power)
VALUES(273, '2014-05-29 14:44:17.713', 800, '-64.91');
INSERT INTO Spec1 (Channel, Timestamp, Lambda, Power)
VALUES(273, '2014-05-29 15:05:09.507', 800, '-59.11');
INSERT INTO Spec1 (Channel, Timestamp, Lambda, Power)

[Code] ....

Example desired results (I hope the formatting works)

Channel | Timestamp | Lambda | Power | Elapsed_Time
______________________________________________________________

Power Pivot :: Sum For Events And Time - Calculate Total Ratio

May 22, 2015

I created a PowerPivot measure which is a ratio Ratio = Number of Events/Time calculated on 12 months. I would like the grand total to be this Rate Sum(Number Of Events)/Sum(Time calculated).

In my Pivot I have one measure which I called Value and this value can have different types depending on one attribute.For instance one attribute is number of events, an other one is time and the third one is ratio.I want to display a custom grand total simple sum for events and time and a calculation of my ratio for ratio.

For instance
                            201501 201502 201503 TOTAL
Number of events           8         10        10     28
Time                             5           5
4     14
Ratio                            8/5       10/5     10/4 28/14

May 13, 2015

I am struggling to calculate Full year in my SSAS Cube. Meaning, regardless of what fiscal year hierarchy level I am in; i need a measure aggregating from 01/01/year of current member to 12/31/year of current member.

I want to replicate it using the Year To Date below:

FY-FQ-FM is the fiscal year quarter hieararchy

I am using for built in time intelligence.

Create Member

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
sudheer racha.

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.

Integration Services :: Exclude Time In Date Time Variable In SSIS For Loop?

Oct 22, 2015

I am trying to load previous days data at 3 am via a SSIS job.

The Date variable is initiated as DATEADD("dd",-1, GETDATE()) in the for loop.

Now, as this job runs at 3 am, and I set the variable as GETDATE() - 1, it excluded the data from 12 am to 3 am in the resultset as Date is set as YYYY-MM-DD 03:00:00:000 I need this to be set as YYYY-MM-DD 00:00:00:000

How can i do this?

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

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?
