Transact SQL :: Window Function To Count Number Of Rows In The Previous 24 Hours?
Nov 16, 2015
is it possible to use the window functions to count the number of rows in the previous 24hours from the current row.
I have a table of events like:
User, TimeStamp, etc...
I want to identify the row which is the event number 50 in the past 24 hours.
does the window functions can do this? and how?
the ROW PRECEDING etc... appear to not have enough feature to support time related function.
Stream-insight is able to create this type of query, but I have to do it directly in SQL.

I want to create a subset of a geography table. My intention is to select only a few cities with a where and after that select a percent of village for each of the cities. My query look like this:
SELECT TOP 160 [CodMunicipio] ,[NombreMunicipio] ,[CodProv],[Provincia] ,[COMUNIDAD AUTÓNOMA]
,[Longitud ETRS89/REGCAN95],[Latitud ETRS89/REGCAN95]
,[XUTM ETRS89/REGCAN95],[YUTM ETRS89/REGCAN95],[Bandera]
--INTO [PracticasSCD].DBO.DIMGEOGRAFIA
FROM [SportFunDW].[dbo].[DimGeografia2] TABLESAMPLE (3 PERCENT)
[Code] ....
I have tried with tablesample but it doesn´t return what I expect because I have many villages from one city (for example 15 % of it) and only 2 % of other. How can I achieve my goal?

Below is the resultset I got using the following SQL statement
SELECT ROW_NUMBER() OVER (PARTITION BY ID ORDER BY create_date DESC) AS RowNum
,ID
,create_date
,NULL AS end_date
FROM dbo.Table_1
Resultset:
RowNum ID
create_date end_date
1 0001
2015-02-18 NULL
2 0001
2014-04-28 NULL
[Code] ....
Now, I want to update the end_date column with the create_date's values for the next row_number. Desired output is shown below:
RowNum ID
create_date end_date
1 0001
2015-02-18 NULL
2 0001
2014-04-28 2015-02-18
[Code] ....

I want to display Days Hours Mins Format.
I am Having two columns Like below,
Col1 (in days) col2 (In Hours : Mins)
3days 4:5
In this first have to add Col1 and Col2 (Here one day is equals to 9 hours ) so the addition is 31.5
From this 31.5 I should display 3 Days 4 Hours 30 Mins because 31.5 contains 3 (9 hours) days 4 Hours and .5 is equals to 30 mins.

My understanding from a previous thread was that ExecuteNonQuery() could be used to display the number of rows returned.
Does this also work when calling stored procedures and passing parameters?
I have code (shown) that perfectly calls and returns Distinct models downloaded by Country. Yet the rowCount variable displays a -1.
What should I do?Dim myCommand As New SqlClient.SqlCommand
myCommand.CommandText = "ap_Select_ModelRequests_RequestDateTime"
myCommand.CommandType = CommandType.StoredProcedure
myCommand.Parameters.AddWithValue("@selectDate", dateEntered)
myCommand.Parameters.AddWithValue("@selectCountry", CInt(selectCountry))
myCommand.Connection = con
con.Open()
Dim rowCount As Integer = myCommand.ExecuteNonQuery()
numberParts.Text = rowCount.ToString
con.Close() Thank you.

I have a really basic question. The following SQL query works for me:
Select EnterUserID, Enterdate
from tblCsEventReminders
where EnterDate >= Convert(datetime, '2015-04-01')
I am essentially trying to write a query to count the number of user logins after a certain date, so I need to count 'EnterUserID' but I am having problems getting the count() function to work.

Hi,Should be quite simple but can someone please tell me the best way tocount the number of rows in an UNION ALL statement.I tried using @@ROWCOUNT but that doesn't seem to contain the correctnumber.Also, I assume that running the query again but just returning count(*)instead of the data is horribly inefficient (plus the code is thenbloated.)?Thanks,Mark

This employee (001) has two weeks below 32. How do I use the COUNT statement to calculate that within these four weeks(columns), how many weeks(columns) have the value below 32?

I am using SQL Server 2008.Each stock item will have default 4 document type (1, 5, 6, 7) and each will have 3 zone's (1, 2, 3) to qualify. Each zone will be updated to 1 for that document type if the item successfully pass through it. If all zone are NULL means no transaction. How to retrieve only the failed rows which means not all zone are 1 or NULL.In the image GJ-00064 has one row failed. So how to get the count of failed rows for each item
Expected result:
Uniid <-> Stockcode <-> FailedRows
1670 <-> GJ-00064 <-> 1

I have 3 tables: Suppliers, Documents and Verification, each document may have multiple verification where I need to get the last verification according to verification date. So I just need a "Select top 1 result from Documents, Verification where doc_iddoc=ver_iddoc and result='True' order by ver_date desc" so far I get the result of the last verification, but here's the problem:
I need to get a row with the count of documents for each supplier, I mean:
Supplier Name Docs NegativeVerification
Acme Co 10 1
that is I would need to loop for each supplier and each document and get the last verification, if one of any of documents have negative verification then add it to negative results. Is it possible to achieve this with a query or do I have to do it through stored procedure?

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'

Consider the following: I have a table, say ORDERS, with these entries -
CustID
ProductID
1 CAN
2 2
3 1,2
4 4
5 1,2,3,4,5,CAN
6 10
7 CAN
8 1,CAN
I'd like to write a script to return only those rows WHERE ProductID = CAN along with other values in the same column. In this example, I'd like to return rows 5 & 8. How can I write this in T-SQL? So, say, check if ProductID has a comma ',' value plus the 'CAN' string. If yes, then return that row. If I use the LIKE operator, it'll return rows 1,5,7, and 8.
