I am new in SQL Server and creating some SQL script that should give total transaction count per hour for a day. I need simply hour and count result. My table contains DateCreated column and unique ID column.

Hi, I'm hoping you guys can help me with a query.
I am trying to write a SELECT statement to return the number of calls received by a Call Centre, grouped by the hour that they are received (i.e to reflect peaks and troughs throughout the 24 hr day). So, my SELECT statement is as follows:
SELECT DATEPART(HOUR, RecvdTime) AS [Hour of Day], COUNT(CallID) AS [Total Calls]
FROM Table1
GROUP BY DATEPART(HOUR, RecvdTime)
ORDER BY DATEPART(HOUR, RecvdTime)
However, the problem of course with this statement is that for Hours where there are no Calls (i.e a COUNT of zero) there is no result returned at all. What I am trying to acheive is for the query to return a result for all hours of the day, and to display a 0 for a particular hour if appropriate.
Can anybody guide me as to an approach for this?
Many thanks
Matt
I have a table with the following columns employeeSessionID, OpDate, OpHour, sessionStartTime, sessionCloseTime. I need to see how many users remain active per hour. I can calculate how many logged in per hour, but I am stumped on how to count how many are active per hour. I have a single table that stores login data. I have created a query that pulls out the only the data needed from the table into a temp table using this query. Also note it is possible that the sessionCloseTime is null if the device has not been logged out this would need to be counted a active.
TABLE NAME #empSessionLog Contains the time stamp data OpDate, sessionStartTime and sessionCloseTime.

[code]....
can see how many sessions logged in per hour with the following statement:
SELECT
opDate,
FORMAT(DATEPART(HOUR, sessionStartTime), '00') AS opHour,
Count(*) AS Total
FROM #empSessionLog
Group BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00')
Order BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00') ASCResults:
opDateopHourTotal
2015-01-20041
[code]....
Where I am stuck is how do I count the sessions that remain active per hour until the session is closed with the sessionCloseTime.
I have a table that is recording hits to a website. Everytime someone views a page, the datetime of the hit is recorded in a field called hit_date_time. I would like to be able to come up with a query that will show how many hits occured on a given day or given days, broken down by hour.
The resulting table for two days would look something like:
Time Hits
1/1/01 12:00 1
1/1/01 1:00 23
1/1/01 2:00 54
1/2/01 1:00 15
1/2/01 2:00 14
I can't seem to figure out how to write the query so that I can take into consideration the date and hour of the event so that I can count it.
Thanks,
Eron
Is anyone currently totalling their transaction count per day? I'm wondering how to do this.
I figure I can stick perfmon tran/sec in a table and total it that way, just wondering about other ways. Thanks.

How do you find out how many transactions sql server is processing? I want to be able to monitor peak and average transaction processing counts over time.
View 2 Replies View RelatedHi,
I would like to capture number of the total transactions made on the server during a day. ie begin tran - commit tran
How can I collect this information?
Is it possible?
Please help.
Hello,
We just migrated one of our databases from SQL Server 6.5 to 7.0. One of our applications (2-tier) used to run this query against the database: "Select rows from sysindexes where name = 'syslogs'" to check the number of rows.
There is no table 'syslogs' in the master anymore. There is no name "syslogs" in the sysindexes. Do you know why don't we have this table and how can I get the number of rows?
Thank you,
Anastasia.
Hello, everyone:
I need total transaction count. @@TRANCOUNT returens the number of explicit transaction. How about implicit transaction? Thanks a lot.

Please find my second post in this thread.
Can anyone help me in sorting out the problem and let me know what might be the reason.

Hi All
I'm getting this when executing the code below. Going from W2K/SQL2k SP4 to XP/SQL2k SP4 over a dial-up link.
If I take away the begin tran and commit it works, but of course, if one statement fails I want a rollback. I'm executing this from a Delphi app, but I get the same from Qry Analyser.
I've tried both with and without the Set XACT . . ., and also tried with Set Implicit_Transactions off.
set XACT_ABORT ON

for reading the data i have write the Dynamic TSQL based on some condition and based on that it is using 25 different function to populate the data into different 25 column. Tsql returning correct data and is working fine in Enterprise manager. But in my SSIS package it show me time out ERROR.
I have increase and decrease the time to catch the error but it is still there i have tried to set 0 for commandout Properties.

Hello people,
I'm migrating an application from asp to asp.net and access to ms sql 2005. On the old db, there's a table with a column to store date and a column to store time. Ms sql only works with date and time together, right? I created a query to get the time from time column and update the date column inserting the time. I did something like this:
UPDATE S_ACC_MONEYSET Date_Oper = CONVERT(varchar, Date_Oper, 101) + ' ' + CONVERT(varchar, Time_Oper, 108)
Does anyone knows a better way to do that? Any other comments?
Thanks!
I have about 23 SQL servers running 6.5 SP3 or SP5a in a 24 hour environment. Most of the activity takes place between 6am and 11pm, with few transaction after 11pm. What is best to do with the main DB's transaction log, have the truncate at checkpoint option checked OR back up the transaction log a couple times a week? The Database is backed up every 6-8 hours.
Thanks in advance for your opinions/help.

Hi All,
I have several servers each with an instance of SQL Server with a number of databases in each instance. We are a law firm dealing mostly with documents (Modifying and creating new). Is there an easy way to determin how many transactions the transaction log handles per hour? Not all tables have a create date or modify date. Is there some way to monitor the transaction logs them selves?
Thanks,
Roy
I have a pretty straight forward fact table that contains order information like this:
DateTimeStamp Price OrderID
I have a measure that does a simple row count for orders placed. How can I get the Max Orders Placed grouped by Hour? Something similar to this:
0:00 15
1:00 25
2:00 50
.....
23:00 75
I tried to do a max function like max([time].[hour], [measures].[Order Row Count]) but ended up with only one value. I know I'm doing it wrong.
I appreciate any help on this.
Hey guys,
I am doing a project that has start time and end time. i was given only the start time of cases, but not the end time.
for example:
start time
01:30:00
10:00:00
09:24:00
11:25:00
.
.
.
.
It was like, thousands of start time. I need to create an end time (smalldatetime) which is one hour passed the start time. can anyone tell me how to do it in sql query? thanks.

Hi
I'm trying to create a query, where I add one hour to a value (I marked it below with "+ 1 HOUR"). I can't find any informations, how I can do this.
Code Block
"SELECT field1, enddate, (enddate < GetDate() FROM table WHERE (enddate + 1 HOUR) < GetDate()"
Does anybody can help me with this problem?
Kind regards

Hi All,
I have an orders table which has a filed called OrderTime which is the exact time when the order was received ? I need to write the following queries
1. Get number of orders per year
2. Get number of orders per month (obviously if a month (for example, november) is in a different year, its to be in a different row)
3. Get number of orders per hour
Note: If there are no orders in a year etc, it should return a row with 0.
How do I get the hour in HH24 format from a datetime value?
Many Thanks.
I am trying to get a count of how many times a badge is entered in each hour it appears. In other words, I would like to find out how many times badge 3333 comes up in each hour of the day, the same with badge 4532.
The task at hand is to find out productivity for items processed per hour per badge number. I know I will need to take the hour out of timedate using datepart, but the results do not look right. Would anyone have any ideas on this? Thanks!
the table I have looks like this:
IDBadgeOrdNumberTimeDate
6112133333781267941/10/05 9:19

Hi all:
As I can extract the hour values and minute of a field of type datetime to compare it with the values of a field of type smalldatetime of another table
Thanks.:confused:
I want to round times down to the previous hour,
For example a call time of 7/31/07 11:51:13.532 would become 7/31/07 11:00:00.000.
