Computing 'SUM' On 'DATETIME' Datatype
Jan 5, 2006
hi everybody,
i'm trying to calculate the 'SUM' of time spent in hrs. n min. How can i do this using SQL Server?
What i mean is, i've a column 'TIME_SPENT' that has 'datetime' datatype. This column saves time spent for an activity in format 'hh:mm'. Suppose a user spends 45min for activity 'A' and say 1hr 25 min for activity 'B' then i want to calculate the 'SUM' of 'TIME_SPENT' for the user which should appear as 'Total time spent =2:10'
Can somebody pls help me with this?
Thnx in advance.

Hi all.
I'm using foxpro and I'm completely new to SQL. I'm trying to create a database into which I need to enter a time field. I've read around on the net that the only way to do this is using a datetime datatype but I can't find anywhere that explains the format I use to INSERT INTO my tables.
Anyone help?
*EDIT* I actually just want to enter the time and not the date and the time, I have read it is possible to do this using a convert but I'm happy enough to have the date and the time as I don't want to overcomplicate anything at this stage.

Are we allowed to do a LIKE datetime in SQL queries?
The records data looks like so:
9/21/2000 10:30:40 AM
But I want to see model requests by an entire day ala:
Select * From ModelRequests Where RequestDateTime Like '9/21/2000%'
But I do know get any records returned.
What is the special way of dealing with the datetime datatype for these purposes?

Hello!
Here's the puzzle I'm trying to solve.
I have 2 columns (CreatedDate and StatusDate) in the table both of datetime datatype.
When I run query
select * from sale
where Statusadate = "11/30/2001" it returns rows back.
When I do the same but for CreatedDate column
select * from sale
where CreatedDate="11/30/2001" it returns zero rows back even if there are CreatedDates = "11/30/2001".
I don't understand why it works for one column and doesn't work for another one.
The example of CreatedDate value is "2001-11-30 10:10:33.000"
Thank you,
Lena

I have a column which has 05MAY2006:04:34:00.000000 it is stored as varchar(25). I need to save it as datetime in the same column. I have tried using
update tablename
set columnname = (SUBSTRING(columnname,1,2) + '-' + SUBSTRING(columnname,3,3) + '-' +
SUBSTRING(columnname,6,4) + ' ' + SUBSTRING(columnname,11,8));
and then
alter table tablename
alter columnname datetime;
but later it shows up the error
Msg 242, Level 16, State 3, Line 1
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
How do I change it any other opinion or any modification for the above query.

For some reason, I recall having read that SQL Server 2005 would supporta datatype that represented date, but not time. (This would be usefulfor storing things like birthday, where you usually don't care about thetime of day). But I've got SQL Server 2005 installed, and there's nosuch datatype to be found.Is this something that might be released in a Service Pack, or is itjust not going to happen?

This question is about selecting datatypes for database fields and related performance and operational benefits.
When creating a database in SQL Server, there are many datatypes that can be assigned to each of the fields.
Below is a example table:
ROOMAS (id, roomsLabel, price, roomName, roomPhone, dateAssigned, userID, roomWidth, roomLength)
Scenario I: Make the id an int datatype, and all of the other fields a varchar datatype.
Scenario II: Make the id an int datatype, and choose various datatypes based on what the field is, e.g. DateTime, int, float, long, varchar
What are the differences in performance between the two scenarios, if any? How does the database engine differ in behavior for both scenarios?
All data is coming from the Presentation tier in the form of a String. By using the varchar type for all fields, there is a reduced level of conversion errors and less conversion code in the business objects.
Thanks.

Hello,
I'm having trouble extracting the datetime value of a datacolumn in order to compare it's value to another datetime. The error I get is "unable to cast object of type System.Data.DataColumn to type System.DateTime. I'm sure I'm just missing a step or a cast, but nothing has worked. I hope someone can help!
Here's the code:
protected void ddlRooms_SelectedIndexChanged(object sender, EventArgs e)
{
SqlCommand cmd;
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["EventBookingConnectionString"].ConnectionString);
SqlDataAdapter da;
DataSet ds;
try
{
cmd = conn.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT Events.ID as 'Event ID', Name as 'Event Name', Rooms.Room as 'Event Room', AttendeeList as 'Attendee List', EventDate as 'Event Date' from Events INNER JOIN Rooms on Events.Room=Rooms.ID";
ds = new DataSet();
da = new SqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(ds, "BookedRooms");
if (ds.Tables["BookedRooms"].Columns["Event Room"] != null)
{
foreach (DataRow row in ds.Tables[0].Rows)
{
string room = (string)row["Event Room"];
if (ddlRooms.SelectedItem.ToString() == room)
{
System.DateTime date = (System.DateTime)ds.Tables[0].Columns["Event Date"]; //HERE'S WHERE THE ERROR OCCURS
if (Calendar1.SelectedDate == date)
{
lblBookedRooms.Visible = true;
lblBookedRooms.Text = "I'm sorry, that room is booked for that day.<br />Please choose another day or a different room.";
}
}
}
}
}
catch (Exception ex)
{
lblResults.Text = ex.Message;
}
}
Thanks in advance to anyone willing to help out!

A SQL Server 2005 db has three date related-columns (MonthGiven,
DayGiven, YearGiven) each as smallint datatype. I would like to
create a DocDate column (datetime datatype) that combines the data from
the three existing date-related columns. I have tried casting and
simple concatentation without success. ALTER TABLE Details ADD DocDate DateTime NULL
UPDATE Details SET DocDate = CAST(MonthGiven AS DateTime)+ '/' + CAST(DayGiven AS DateTime) + "/" Cast(YearGiven As DateTime)
I think I need to be doing a Conversion instead of casting but
have been unable to implement info I have found in the SQL Server
Developer Center in my situation.

Hi,
I have a requirement to be able to select and group records by the date portion of a datetime field. ie ignore the time when grouping so that all records lodged on a particular day are seen together.
I have been able to do this by
- converting the datetime data to the number of days since a given date
- inserting this into a temporary table
- retrieving the the data from the temporary table
- convert the data back to a date using DATEPART to display dd/mm/yy
This then gives me the data grouped as required but seems to be a very difficult solution - Is there an easier way??
Thanks in advance

I have a sql server express 2005 database with a table named Events with a column named Date (datetime datatype). I want a query that will display all rows that are either current or future but not past. I suspect there is a simple way of doing this. As a Newbie searching archived threads this is what I have come up with so far. I determine the number of days from present:SELECT DATEDIFF(day, Date, GETDATE()) AS NumberOfDays FROM EventsThis yields number of days from present with positive numbers in the past and negative numbers in the future. Thus setting a WHERE clause to <= 0 would limit my results to present or future events. Something like this:SELECT * FROM EventsWhere DATEDIFF(day, Date, GETDATE()) AS NumberOfDays <= 0The error message states: "Incorrect syntax near the keyword 'AS'"This feels like a clumsy way to approach this problem, but I have to start where I am.Any suggestions on how to proceed will be greatly appreciated.
