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.
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
TransactionsImport (which is the destination table) TransactionsImportDelta
I need to do the following:
Get the records with the latest date and time in the destination table TransactionsImport Get the records with the latest date and time in the destination table TransactionsImportDelta table Insert the records from the TransactionsImportDelta table into TransactionsImport that have a greater date & time than the current records in TransactionsImport table.
Problem is date & time are in separate columns:
Table structure:
Date Time ID 2011121305154107142201008300100 2011121305154122B1L13ZY0000A07YD 2011121304504735142201090002600 2011121304504737142201095008300 2011121304504737142201090002600
creating the missing records in a date/time range.
However, I need to return different groups for each span of records.
here's some data....
aaa1 aaa7 bbb2 bbb5 bbb6
The numbers are the hour of the day.
I need to return
aaa 0 0 aaa 1 1 aaa 2 0 aaa 3 0 ... bbb 0 0 bbb 1 0 bbb 2 1 ... and so on.
I've got a numbers table and I can left join with it but I just get nulls for the missing hours instead of having it as above.....I can't think of a way of repeating the groups for each of the 'missing' hours - other than creating a length insert statement to fill in the gaps....unless that is the only way of doing it.
I'm trying to get a count of Employed and Available contractors per time period, and I have a table of Contracts... something like:
CREATE TABLE empContract( empContractID INT IDENTITY(10000,1) PRIMARY KEY, StartDate DATE NOT NULL, EndDate DATE, ContractorAssigned INT, FOREIGN KEY ContractorID REFERENCES Contractor(ContractorID) );
I don't think this is possible without the existence of some kind of Calendar table. Given the existence of a calendar table, the query seems really simple - just something like:
SELECT cal.CalendarDate, ec.ContractID FROM Calendar cal LEFT JOIN empContract ec ON cal.CalendarDate BETWEEN ec.StartDate AND ec.EndDate
The left join forces the existence of all dates in a range (@StartDate and @EndDate), so that when I try to create a graph with counts by day, I don't have any gaps in my time series.
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,
SELECT (TO_CHAR(ASOFDATE,'YYYYMMDD')||' '||TO_CHAR(ASOFTIME,'HH24:MM : SS')||':000') AS ASOFDATE
FROM TBLA
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.
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 @startdate date = '03-06-2015' DECLARE @enddate date = '10-31-2015' DECLARE @afterTime time = '17:00' SELECT General_Count = (SELECT COUNT(*) as General FROM Unidata.CrumsTicket ct
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:
I have these two tables Log and CategoryLog, I need to archive records older than 13 months in these two tables to two separate tables and then delete the archived records from Log and CategoryLog tables. The problem is that only 'Log' table has a date column, the other table CategoryLog does not have any date column. But the two tables are connected by a column(LogID). How to archive the data and then delete the archive data from both tables.
I am using the following views from two db's to find records that don't match.
My question is can I have output of fields from the second table
SELECT distinct T1.[last name],t1.[first name],ENum FROM ECLINICIAN_Info T1 WHERE NOT EXISTS(SELECT * FROM ACLINICIAN_Info T2 WHERE t1.Enum = t2.Anum and t1.[last name] = t2.lname and t1.[first name] = t2.Fname)
i have a table of phonecall records detailing amongst other things the time and duration of the call. there is a relationship linking this table to a table of handsets and from there to a table of users. this users table lists the start date the user had the phone. as ever sample data might make this easier to show:
PhoneUsers table
PhoneUserID Name StartDate PhoneID
1 john 1/08/2006 1
2 bob 20/08/2006 1
3 fred 2/08/2006 2
etc
Phones table:
PhoneID
1
2
etc
PhoneCalls table:
PhoneCallID PhoneID CallDate Duration
1 1 10/08/2006 25
2 1 23/082006 20
3 2 23/08/2006 20
i want the following result set:
user calldate duration
john 10/08/2006 25
bob 23/08/2006 20
fred 23/08/2006 20
essentially i am trying to link the phonecalls to the user of the phone at the time of the call. i make the following assumptions regarding the data:
the user is responsible for all calls for a given handset from the 'startdate' until the next 'startdate' for a different user, if such a record exists, if not then for all calls after that date
Looking to see if thier is a better way to find the last record entered in a group of records.
What I'm doing now is finding the max for the secound column and then doing a sub query to find the max of the third column having the second columns equal.

The parent program addes a row every time the data is changed. To make things worst; the records arn't always in sqenal order like the above table and some time edits the row instead.
The current query returns a single value. from a single table.
Current code used in the select protion on a larger query. bpi = basicpolicyInformation.
( Select c1.limit1 From AFW_Coverage as c1 Where c1.PolId=bpi.PolId and c1.CoverageId = (select max(CoverageId) as CoverageId From AFW_Coverage as c where c.PolId = c1.PolId and c.CoverageCode = 'Dwelling' and status <> 'D' ) and c1.effDate = (select max(Effdate) as Effdate From AFW_Coverage as c where c.PolId = c1.PolId and c.CoverageID = c1.CoverageId )
Explain the current code. It uses the two sub queries to find the correct record ID that has the data needed.
For this id: 0793319, my beginning date is 2011-09-06
108203492014-09-022015-06-30 208203492013-09-032014-09-01 308203492012-09-042013-09-02 408203492011-12-122012-07-03--not a continuous date range
For this id: 0793319, my beginning date is 2012-09-04
108203492014-09-022015-06-30
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.

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.
How to find last login date/time for user DML acitivity on databases on Instance?
Is there any way we can find our the last login date/time for databases?
Note: 1. We can find if the SQL Trace is running and store.This is not good solution 2. Audit logins off/on is also not good solution. 3. Using DMV's also not good option, if reboot sql server instance then historical values can not see.
I have a scenario where I have to Update a table with date when there are new records in another table
For example:
I load ODS table with the data from a file in SSIS. the file has CustomerID and other columns.
Now, when there is new record for any customerID in Ods, then Update the dbo table with the most recent record for every CustomerID(i.e. update the date column in dbo for that customerID). Also Include an Identifier that relates back to the ODS table. How do I do this?
Below is the code for two data sets and I can't seem to get my head around the issue. I need to find the number of 'ER' visits and 'IN' visits, separately, in dbo.VisitData for the 'Active' patients in dbo.PatientStatus. So, consider patient 69. He is Active on 5/5/2014 but becomes Inactive on 9/15/2014. I only want to count the number of visits ER or IN that are between those dates. In addition if patient 69 becomes active again after 9/15/2014, I need to capture that data as well. Patients can change there status multiple times.
Generating the 4 lines is not the issue; I call 3 functions to do that together with cross apply.One function to get all dates between the start and end date (dbo.AllDays returning a table with only a datevalue column); one function to have these dates evaluated against a work schedule (dbo.HRCapacityHours) and one function to get the absence records (dbo.HRAbsenceHours) What I can't get fixed is having the correct hours per line.
I have the table with the similar set of records which mentioned below, find the time difference between two rows of record. By Using the MsgOut column i have to find time taken b/w PS & PV and some record doesnt have PV .
I am developing a form for a mortgage company. There can be any number of borrowers on a given loan, and the business has asked that this form return only 2 borrowers at a time for a loan. For example, if there are 3 borrowers for a loan, they want the first copy of the form to print the first 2 borrowers and then another copy of the form to print the 3rd. No matter how many copies are printed, they want the borrower information to be labeled as 'Borrower1' xyz and 'Borrower2' xyz. Also, there will be a LOT more fields returned on the real form, so the sample information below is very simplified test data.
I don't want that 2nd record to return. This result is what makes me think of gaps and islands, but I don't know if the 2nd record is really an island since it's (1) not stored this way...it's returning this way because of the query and (2) it's not sequential data..I tried restricting this by putting this into a CTE and then returning only the odd numbered records like I have below. This runs pretty quickly when dealing with one loan. But...I am concerned that the CTE will be slow when we run batches of loans.
Attempt with CTE: --With CTE ;WITH cte AS (SELECT Borrower1 = BorrowerName , Borrower2 = LEAD(BorrowerName) OVER(ORDER BY BorrowerOrder) , RowNumber = ROW_NUMBER() OVER(ORDER BY BorrowerOrder)
[code]...
Is there a better, cleaner way to do this? Or is the CTE the best way to go?
Hi there. I'm trying to extract data from my SQL server & everything in the script I've got is working (extracting correct data) except for one field - which is for the most part it's off by +2 days (on a few occasions - I see it off by just +1 day or even +3, but it's usually the +2 days).
I'm told that it's due to the conversion formula - but - since SQL is not my native language, I'm at a bit of a loss.
The DB table has the date field stored as a type: CHAR (as opposed to 'DATE') Can anyone out there help?
A server with SQL 2005 sp2, Reporting Services and Sharepoint services (ver 3.0) (in integrated mode) gives an odd error. When viewing a Reporting Services report with a Date Time Picker, the date chosen is wrong. The preferred setting is Danish with the date format dd-mm-yyyy. The date picker shows the months in Danish but when selecting a date, and clicking on the Apply-button, the date reformats to US (mm-dd-yyyy).
Example: When choosing 5th of September 2007 and clicking apply, it shows in the picker, 9th of May 2007. When choosing 26th of September 2007 and clicking apply, it shows, again in US format, the RIGHT date but adds a timestamp 12:00 AM? in the end, making further enquiries to fail.
The report itself receives the right date and shows correctly. The only case it fails is, when the time stamp appears.
The server is a 32-bit one with 4 GB RAM. A testserver with identical collation on the Reportserver database cannot recreate the error. The site containing the reports has been set to Danish in the regional settings. To Reinstall is not an option.
The test report has no database connection whatsoever.
When setting the site to US, the timestamp wont appear at all.
The server has been restarted and the installation procedure was of the simple kind. No special tweaks at all.
