SQL Server 2008 :: Loop Through Date Time Records To Find A Match From Multiple Other Date Time Records?

Aug 5, 2015

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.


Query 1

Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'


Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'

Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.

I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

Conversion Of Oracle Date Time To Sql Server Date Time In SSIS

Jun 30, 2007

This is driving me nuts..

I'm trying to extract some data from a table in oracle. The oracle table stores date and time seperately in 2 different columns. I need to merge these two columns and import to sql server database.

I'm struggling with this for a quite a while and I'm not able to get it working.

I tried the oracle query something like this,



this gives me an output of 20070511 23:06:30:000

the space in MM : SS is intentional here, since without that space it appread as smiley

I'm trying to map this to datetime field in sql server 2005. It keeps failing with this error

The value could not be converted because of a potential loss of data

I'm struck with error for hours now. Any pointers would be helpful.

SQL Server 2008 :: Estimate / Calculate Performance Overhead From Replication?

Jun 10, 2015

I've been asked to put together an estimation for the performance impact that replication would have on our database server during a particular operation. I know that this depends on a lot of different factors, including:

* Number of articles being replicated
* Types of articles being replicated
* Number of DML transactions that would result in delivery of replicated data

Any way to turn this into a meaningful metric?

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:

Here are some examples of a record:

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?

SQL Server 2008 :: How To Calculate Number Of Days Since Start Of Fiscal Year

Jul 29, 2015

Our fiscal year starts on July 1st. Each month they call a period - so July is period 1, August is period 2, etc.

They are wanting a report that pulls numbers for a given period. There are parameters for them to select the fiscal year and the fiscal period, and then it calculates the numbers for that period. That part works fine.

Now they want me to do some calculations, and one of them is to divide one of the numbers by the # of days since the fiscal year. So if they choose July, it would be 31 days. If they choose August, it would be 61 days, etc. How can I set this up to calculate the number of days when they really aren't entering a start date, it's just a fiscal year and period.

Is there a way to calculate a date field that is 07/01/xxxx where xxxx is the fiscal year they chose? Also a way to calculate a date field that would be the last date of the month for the fiscal period and year they chose?

I suppose I could add 2 other parameters where they enter the start of the current fiscal year, and the last day of the period they're running it for, and use a datediff to calculate that. Just seems kind of redundant.

SQL Server 2008 :: Calculate Number Of Months Between Dates For Multiple Records?

Oct 7, 2015

I have a challenge and I'm not sure the best route to go. Consider the following dataset.

I have a table of sales. The table has fields for customer number and date of sale. There are 1 - n records for a customer. What I want is a record per customer that has the customer number and the average number of months between purchases. For example, Customer 12345 has made 5 purchases.

CustomerNumber SalesDate
1234 05/15/2010
1234 10/24/2010
1234 02/20/2011
1234 05/02/2012
1234 12/20/2012

What I want to know is the average number of months between the purchases. And do this for each customer.

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

USE SpecTest

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
273 | '2014-05-29 14:44:17.713', | 800, | '-64.91' | 0
273 | '2014-05-29 15:05:09.507', | 800, | '-64.91' | 00:20:51
273 | '2014-05-29 15:26:00.520', | 800, | '-64.91' | 00:41:42
273 | '2014-05-29 16:28:34.213', | 800, | '-64.91' | 01:44:16
273 | '2014-05-29 16:49:25.853', | 800, | '-64.91' | 02:05:08

SQL Server 2008 :: Finding Beginning Date From Multiple Lines Of Date Ranges?

I am trying to find a beginning date from multiple date ranges, for example:

408203492011-12-122012-07-03--not a continuous date range

For this id: 0793319, my beginning date is 2012-09-04


For this id: 0820349, my beginning date is 2014-09-02

To find continuous date, you look at the beginning date in row 1 and end date in row 2, then if no break in dates, row 2 beginning date to row 3 end date, if no break continue until last date There could multiple dates up to 12 which I have to check for "no break" in dates, if break, display beginning date of last continuous date.

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

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.

SQL Server 2008 :: Restore Database To A Point Of Time

Sep 1, 2015

Can I use a full and differential backup to restore to a point of time?

Or I have to use full and transaction log backups in order to do a point of time restore?

I found today when I tried to restore a db from another database at the point of time for example 3:10 pm,
SSMS automatically select the full backup + the transaction backup that is done at 3:00 pm, but not select full + the differential backup I did at 3:12pm.

So I lost those records entered after 3:00pm.

I supposed it should use the differential backup and restore to 3:10. but it didn't.
