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 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

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.

I need to delete records from a table (Table1) which has a foreign key column in a related table (Table2).

Table1 columns are: table1Id; Name.  Table2 columns include Table2.table1Id which is the foreign key to Table1.

What is the syntax to delete records from Table1 using Table1.Name='some name' and remove any records in Table2 that have Table2.table1Id equal to Table1.table1Id?

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 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.

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 08:40:00

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

Transact SQL :: Adding Count Before And After A Specific Time Doesn't Match Total Number Of Records

Nov 19, 2015

If I just use a simple select statement, I find that I have 8286 records within a specified date range.

If I use the select statement to pull records that were created from 5pm and later and then add it to another select statement with records created before 5pm, I get a different count: 7521 + 756 = 8277

Is there something I am doing incorrectly in the following sql?

DECLARE @afterTime time = '17:00'

Looping Thru Records To Find Related Records

Oct 31, 2007

Hi, I have had this problem for a while and have not been able solve it.

What im looking at doing is looping thru my patient table and trying to organise the patients in to there admission sequence, so when patient "A" comes in and is treated at my hospital and is discharged and admitted to another Hospital within one day then patient "A" will get a code of 1 being there first admission.

then if patient "A" is admitted again but there admission date is greater than one day they get a code of 2 being for there second admission but will need to loop thru table looking for other admissions and discharges.

The table name is Adm_disc_Match_tbl

Basically what i have 4 fields.
Index_key = which is the patient common link (text)
ur_episode = this wil change for each Hospital (text)
Admission_datetime = patient admission date and time (datetime)
Discharge_datetime = patient discharge date and time (datetime)

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.

E.g.

Query 1

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

Table

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.

Count Of Related Records??

Jul 23, 2005

Hi,I was wondering if it was possible to build a query that will include acolumn that will provide a count related records from another table.Although there is a way to achieve this through programming in thefront end, I would like to know if it possible to achieve the samething through a SQL statement alone.For example, say you have two related tables, Invoices andInvoiceItems. InvoiceID is the primary key of Invoices.Invoices tableInvoiceID PO_Num CompanyID-------------------------------1 37989 32 87302 43 78942 3InvoiceItems tableItemID InvoiceID PartNo Qty---------------------------------------1 1 ABA 32 1 ASLKDJ 23 1 9LF 84 2 IEPOW 185 2 EIWPD 36 2 DSSIO 17 2 EIWP 58 2 DC93 49 3 85LS0 8Then a query that has the Invoices table plus a count of InvoiceItemsfor each InvoiceID would generate this:InvoiceID PO_Num CompanyID ItemCount-------------------------------------------------1 37989 3 32 87302 4 53 78942 3 1Does anyone have any ideas how this would be done?Thank you.

Cumulative Related Records From Hierarchy

Morning chucky eggsThis is duplicated over at SQLTeam...except I've moved on a bit so my question to you is different:http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=103798SQL 2k5I have a standard hierarchy in an adjacency table modelling business units in an organisation. I have another table associating people with (one single) business unit. I need to return all the people in each business unit in a cumulative manner i.e. a unit will include all people assigned to that unit and assigned to all child units too.Below is1) Set up code (in red)2) Initial query that failed on last data load due to the nature of the data changing and me not considering the ramifications of my initial solution properly3) My new soulution.My question is - is there a better way to accomplish this?

Oh hai

This is closely related to this problem where Ryan & Peter helped me out loads (thanks again guys):
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=101989

I now have a slightly different problem. Instead of returning the cumulative counts of people related to a business unit in the hierarchy I now need to return the actual people records. I had some code, derived from the above, that worked fine until I loaded some new data. It took a while but eventually I figured out the (now obvious) reason for the error. I have tried several changes to the query and not got anywhere. Please could someone have a look and see if you can suggest the required alteration(s)?

Running Total Of Records Related To Hierarchy

Apr 15, 2008

Hi guysI'm mulling over the best way to do something and would like your input. Forgive me if this is a bit 101 - I haven't ever had to do this in SQL before!Fairly standard set up - Hierarchy table modelling the structure of an organisation.Related table associating members of staff to the hierarchy.I want to return all levels of the hierarchy and for each level I would like to know the total number of people in the level (so for a division it would be the sum of all people in the child teams).Parameters - This table will be modelling many organisations' structures - I cannot guarentee anything like "there will never be more than n levels". As such - I would strongly prefer to have something that is iterative recursive. I can change the schema to suit the method I use if necessary. Database is not transactional - I am not concerned about updating speed. SQL Server 2K5.I've tried CTE but it turns out you cannot use group by in CTEs (even in derived tables). I have not yet tried feeding it a view or similar.I have not tried nested sets, materialised paths, accumulator table - I thought I would see if there is something obvious before I start piddling around with those.Ta!

Running Total Of Records Related To Hierarchy

Apr 30, 2008

SQL Server 2005.
Schema is not fixed at this stage - small project, schema can be adapted if neccessary.
This needs to be produced in SQL Server - there is no client application.

Hi

I am really struggling to write the SQL for the following requirement and have got to the stage where I think I need someone to give me some pointers. I can't believe this is a novel requirement but I haven't had to do this before nor can find anything similar when googling.

I have a hierarchy detailing an organisation structure. Eventually the table will store many structures and these may one day be "pseudo structures" to enable really granular reporting. As such I cannot really say "there will never be more than N levels to this hierarchy". Currently I'm using a standard adjacency design. From now on I'll call the items in the table "business units".

There is a further table with a related FK declared which associates people with business units.

Requirement: Return all business units and cumulative total total of employees for each of these units (i.e. the total for each business unit will be the number of people in that unit plus the sum of the people in all the child units).

I've asked this question on dbforums but ended up a blind alley despite Peter's attempt to help. I'm starting again from scratch but feel free to review the (now dead) thread here:
http://www.dbforums.com/showthread.php?t=1629366

To summarise - I tried the CTE route but of course this evaluates the hierarchy from the top down. To fulfill the requirement, the bottom of the structure needs to be the starting point. I also tried reversing the hierarchy so that children, rather than the parent, are stored but my query fails if there are 3+ levels.

Code to reproduce problem (note - I expect that I will need to get the employee count per business unit prior to working with the hierarchy so I have flattened the schema to reflect this - I think I can handle the SQL to get the non-cumulative count per business unit ):
DECLARE @table TABLE
(
unit_codeTINYINT
, parent_codeTINYINT
, headcountINT
, PRIMARY KEY CLUSTERED (unit_code)
)

INSERT INTO @table (unit_code, parent_code, headcount)
SELECT 1, 4, 10 UNION ALL
SELECT 2, 4, 130 UNION ALL
SELECT 3, 10, 93 UNION ALL
SELECT 4, 10, 7 UNION ALL
SELECT 10, NULL, 1

Required output:

unit_codecumulative_headcount
------------------------------------
110
2130
393
4147
10241

Many thanks

SQL Server 2012 :: Getting Related Records Set Based Results

Sep 29, 2015

I have a table that has multiple transactions for stock items.

This table holds all records relating to items that are inducted onto the system and there movement. For each stock item i am interested in getting the drop destination, if it has one, and only when it follows the sequential order of "Inducted>OnTransport>Dropped" (this sequence isn't always the case). Also note the CreatedDate for the Inducted and OnTransport records for the valid sequences are always the same. Below is a valid sequence for a stock item so i would want to return 'Lane01' for the Destination of this occurrence of the stock item, if this item didn't have a valid drop location then destination would be blank. Also note each stock item can be inducted more than one time per-day.

I think i have managed to build the below sql but it will only do one item at a time, so would have to wrap it in a function. Is there a way of writing a set based select statement that gets all the inducted items and for the ones that do follow the "Inducted>OnTransport>Dropped" return the destination it was dropped at? I've attached scrips below:

DECLARE @StockItemID nVarchar(128)
DECLARE @CreateDate DATETIME

Set @StockItemID='8cbe17da-6079-4170-b27a-41c0d38830f6'
Set @CreateDate = CAST('2015-08-31 13:52:39.890' AS datetime)

[Code] ....

Terminology Question - Set Of Related Records In Multiple Tables

Jul 20, 2005

Terminology question:Is there a term for a set of records related directly or indirectly by keyvalue in several tables? For example, a single invoice record and its lineitem records -or- a single customer, the customer's orders, the order linesfor those orders, the customer's invoices, and the invoice lines for thoseinvoices.I'm thinking the term might be graph, but I'm not at all certain of this.Thanks,Steve J

Transact SQL :: Extracting From 3 Related Tables And Including MAX Function

Oct 5, 2015

I have these 3 tables in a database for printed chamber music works:

Table INSTRUMENTS: List of musical instruments
    Column ID          -- int, primary key
    Column sInstrument -- string

Table PTRS_INSTRUMENTATION: 
    Column ID          -- int, primary key
    Column lInstrument -- int, points to a row in table INSTRUMENTS via ID
    Column lMainItem   -- int, points to a row in table MAINITEMS via ID
    Column lInstrSeqNum -- int, sequential number of like instruments within one Main Item
    
Table MAINITEMS: List of chamber music works
    Column ID          -- int, primary key
    Column sItem       -- string
    
Each chamber music work (Main Item) requires an ensemble of musicians playing several instruments. Some of them may be the same, such as 2 violins. A classical quartet, for instance, consist of 2 violins, 1 viola and 1 cello. I am concerned here only with one of the instruments (although it may occur several times).

I want to extract a list of Main Items where the instrument is given (e.g., 'violin'),

And the maximum of PTRS_INSTRUMENTATION.lInstrSeqNum is a given number (e.g., 2).

Thanks for your time,
How to calculate & save a Parent status [qcStatus varchar(30)] and Alert [alertFlag bit] in dbo.a1_qcParent
based on comparison of its Child records in dbo.a3_qcItems2Fix columns [itemComplete bit] and [alertFlag bit]
Where a1_qcParent[a1_id] = a3_qcItems2Fix[a1_ID]

- Parent CLOSED: if all children [itemComplete] are True
- Parent OPEN: if any child [itemComplete] is False

- Parent ALERT: True if any child row [alertFlag bit] is True

Using sql_Datasource in webpage, but more comfortable in sql... After-Trigger?
Can Parent columns have calculated formula referencing the child table? Please help.

Transact SQL :: Get DataTypes And Other Schema Related Data Of Columns In A Query

Sep 11, 2015

Is it possible to get data-type,default-value, etc. (basically schema information) of columns in a particular query.This is something similar to what we get when we execute the following 

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Employees'

But instead of TABLE_NAME i would like to give a query like

SELECT [EmployeeID],[LastName],[FirstName] from [dbo].[Employees] order by [EmployeeID].

T-SQL (SS2K8) :: Delete All Rows Satisfying Certain Condition From Table A And Related Records From B And C

Apr 14, 2015

I have around 3 tables having around 20 to 30gb of data. My table A related to table B by a FK and same way table B related to table C by FK. I would like to delete all rows satisfying certain condition from table A and all corresponding related records from table B and C. I have created a query to delete the grandchild first, followed by child table and finally parent. I have used inner join in my delete query. As you all know, inner join delete operations, are going to be extremely resource Intensive especially on bigger tables.

What is the best approach to delete all these rows? There are many constraints, triggers on these tables. Also, there might be some FK relations to other tables as well.

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.
