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.
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.
Hello Probably a very simple problem, but im stumped. I have a table which gives the start-time and end-time of an employees work day. I want to create a view which contains a line of data for each 5 minute period worked. Please help.
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
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)
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.
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.
I know this table is designed wrong for what I am doing but I hope Ican do it. I have a table like this.Prod_A_Jan, Prod_A_Feb, Prod_B_Jan, Prod_B_FebI want a query that returns data like this (two rows of data)"ProdA", Prod_A_Jan, Prod_A_Feb"ProdB", Prod_B_Jan, Prod_B_FebI know two queries can get it but I want one. Any Help would begreat!!!Sheila T.
HI All, I need help in sp. I have the sp that return the result but then i also want count how many rows are the result. Does anyone know how to do that?
This is my sp, and when it returns the data i also want it to return the how many rows are the result.
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.
I have a question, Select top 10 * from employee the above statement return top 10 row. but i want the rows from the table other than the top 10. Can any one help me to get it.. iam using SQL server 2005
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 SELECT SUM(col22) AS SUM_COL22 ,cast(null as int) as c1,cast(null as int)as c2,cast(null as int) as c3FROM table2WHERE TABLE2 = nn)
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
What is the easiest way to return rows 200 through to 300 of a 500 row result set using SQL? Is there a simple way of doing this or do I need to write some Transact SQL? Any ideas would be appreciated.
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.
How can a SQL statement be written to return a specified range ofrows? For example:-- tblContact-- (-- SSN char(9),-- FirstName varchar(50),-- LastName varchar(50)-- )-- This table contains 500 rows.Select * from tblContact -- Return only rows 5 through 10Thanks

Hello, I have a stored procedure that accepts a number of different input parameters that populate some variables in my stored procedure. I want to have this stored procedure return nothing if some of these variables aren't filled out (they are populated by a search page the user fills out). I'm not very familiar with writing stored procedures, so any help you can give me is appreciated. Thanks!
When querying any of our database tables (returning all rows from within the enterprise manager) we are getting the following error message: "The query cannot be executed because some files are either missing or not registered" Can anyone help me with this....
I am new to SQL Server 7 and get the following error message when I go into the Enterprise Manager, select a specific table, right mouse click, open table, return all rows:
"An unexpected error happened during this operation.
[MS Design Tools] - Query designer encountered a MS Design Tools error: Not Implemented"
Can anyone explain what is causing this error?? I can go into SQL Query Analyzer and do a SELECT against any table and bring back data, but not as stated above.
