Need To Only Return Rows In 5 Minute Intervals
Mar 6, 2012
I have collected perfmon data that is in every 15 seconds. I need to run a query that will only retrun rows that are 5 minutes from the last row starting at a specific date/time.
Here is the current query
Select
DisplayString,
MachineName,
ObjectName,
CounterName,
InstanceName,
[Code] ......
"CounterDateTime" is in every 15 seconds. So starting from '2012-03-02 11:59:00' I need only rows for every 5 minutes after that.

I have two fields ID and Log data and log data is a 96 character long string of numbers representing 15 minute intervals from midnight to midnight.
I need to convert these 96 characters to a full 1440 characters which would mean taking each of the 96 characters one by one and making 1 character into 15.
I had Vb macro to do the conversion but now it's broken and I can't fix it. Getting it done in SQL would solve a lot of problems.
I then go from the 1440 fields and do log analysis like total time doing a specific activity but my query is dependent on having all 1440 characters.

I have a situation where I have table with over a billion records and needs to be scrubbed. Table does have a field with date time timestamp. I have been deleting rows from the table using the script below which basically provides me delete statements by date for records older than 90 days.
But now on each day row count is over 30 million rows and it takes forever to delete by date and transaction log becomes humongous.
So I would like to scrub it in 5 minute intervals instead of daily for records older than 90 days. Even in 5 minute intervals the record count tends to be around a million. This will keep the delete slice small enough to not a gigantic transaction log.
declare @startdate Datetime
declare @enddate Datetime
set @startdate = getdate()-480
set @enddate = getdate()-90
--set @vStart = select convert(varchar,@startdate, 102)
print @startdate
print @enddate
WHILE (@startdate < @enddate)
BEGIN
print 'delete from vending where DetectedDate < ''' + CONVERT(varchar(10), @startdate, 101) +''''
set @startdate = @startdate+1
END
I am hoping to modify the script above to produce a script with statements like this for a window between last 90 and 120 days:
delete from vending where DetectedDate <'6/15/2015 8:25:00 PM'
go
delete from vending where DetectedDate <'6/15/2015 8:30:00 PM'
go
delete from vending where DetectedDate <'6/15/2015 8:35:00 PM'
go

I'm trying to create a query to return Open, Close, Max and Min Price for each 1 minute interval. Source data has two fields - Price, and Datestamp at 5 second intervals.
I can calculate the Max and Min (below) and set the datestamp to the middle of the interval, but get stuck on how to also return the Open and Close price for each interval.
SELECT MAX(price) AS MaxPrice, MIN(price) AS MinPrice,
DATEADD(ss, 30, DATEADD(n,DATEDIFF n, '1/1/2006', DateStamp),'1/1/2006')) AS DateStamp
FROM MasterData
GROUP BY DATEDIFF(n, '1/1/2006',DateStamp)
Any ideas?
thanks in advance.

Just wondering what is the best time to ensure that we only return data when the datetime field is the same when compared between two datetimes within a minute difference.
As in the following should return the data:
'2015-04-09 09:00:20' compared to '2015-04-09 09:00:50'
And the following should not return the data:
'2015-04-09 09:01:20' compared to '2015-04-09 09:00:50'
The problem, is that I'm merging data from three different result sets, which they all have data for every minute, however, the timestamp can be different by seconds or milliseconds.
So, I'm only interested to return the data when the two fields that I'm comparing are equal within a minute. I need to ignore seconds and milliseconds.

Hi All,
I am using sql server 2005. I stuck out in a strange problem.
I am using view in my stored procedure, when I run the stored procedure some of the rows get skipped out means if select query have to return 10 rows then it is returning 5 rows or any other but not all, also the records displyaing is randomly coming, some time it is displaying reords 12345 next time 5678, other time 2468.
But if I run seperately the querys written in SP then it returns all the rows. Please give me solution why it is happening like this.
There are indexes in the tables.
Once I shrink the database and rebuild the indexes, from then this problem is happening. I have rebuild the indexes several time, also updated the statistics but nothing improving.
But nothing is improving

Trying to do a paging scheme without using #Temp tables in MS SQL 7.0
Client calls a sp passing 1 and sql returns the first 100 records.
Client sends a sp passing 100 and gets the next 100 records.
Process continues till @@fetch_status <> 0 or the client can stop sending requests.
I implemented it easily using fetch absolute into a #temp table but this has dissaster potential in a multiuser environment since everyone will be using this query continously and there is no user limit.
What other options do I have?
Thanks,
John

hi,i have a stored procedure like this in SQL server ,it returns proper value if data is there for a given id.But if there is no data,it returns row/rows of NULL value and that is counted towards "number of row returned"..Shouldn't it be like,if there are null values in a row,that row should not be counted towards rows returned value .?Rightnow if no value returned from either of the select,it still returns as 2 rows instead of 0 rows.How do handle this situation in SQL? thanks for your help
SELECT SUM(col1) AS SUM_COL1, SUM(col2) AS SUM_COL2, SUM(col3) AS SUM_COL3, SUM(col4) AS SUM_COL4FROM TABLE1WHERE (ID = nn) UNION all

I have a database that has 100,000+ records in a table. Am I better off returning all of the records from a search even if it is 50,000 records or is it better to do a SELECT COUNT(*) And nested SELECT TOP x statements to only return 1 page of results? What is the best practice for a situation like this?
SELECT * FROM myTable LEFT OUTER JOIN ... LEFT OUTER JOIN......WHERE something=@something AND another.... AND...
OR
SELECT COUNT(*) FROM myTable LEFT OUTER JOIN ... LEFT OUTER JOIN......WHERE something=@something AND another... AND... ORDER BY @OrderAnd
SELECT TOP(@pagesize) FROM (SELECT TOP(@pagesize * @pagenum) FROM myTable LEFT OUTER JOIN ... LEFT OUTER JOIN......WHERE something=@something AND another... AND... ORDER BY @Order)ORDER BY @revOrder

Does sql server have a mechanism (aside from count()) that for any given SELECT query will tell you only how many rows it will return without actually returning the data?
The reason for this is that we have a generic lookup form in an application that is used on almost every screen (we have a lot of screens, so it gets a lot of different, sometimes complicted, queries passed to it to use for the lookup, and having to manually edit the query to use count over all the select clauses doesn't seem like the best way to handle this. If we could do a kind of 'trial run' against the server just to get the number of rows and use that to help set up the form, that would be ideal.

The following query returns 2142 rows which is correct.
Code:
select COUNT(*), sum(v.currentMarket)
from TRMaster m
inner join TRValue v on v.Year = m.Year and v.Parcel = m.Parcel
inner join TRProp p on P.PropCode = V.PropCode and p.PropType = 'A'
where m.Year = 2013 and m.deleted = 0 and m.ReviewDateTime is null and m.Status = 1
group by m.Year, m.Parcel
having SUM(v.currentmarket) > 0
How can I convert this query so that it returns just the count of 2142?

I have a Dataset that I am populating from a SQL Query. I am then using the dataset to populate a report in Reporting Services. What I want to do is return a standard number of rows in my dataset. (Let's say 10.) Even if my query does not have any rows in it, I want 10 empty rows returned to the dataset. If my query has 7 rows in it then I want to add on 3 empty rows and return it. I will not have more than the standard number of rows.
I cannot get the table in the report to show up if the dataset is empty, but still want the table to display with 10 empty rows. I have searched how to do this online but am getting nowhere. (I know how to add one empty row but not a set number.
