Hi, I have a table with 3 columns ( Id int, theValue float , aDate datetime). I want to select the number of rows (count) for which the interval of aDate is less than 7 seconds. Is there a way to achieve that in a single query.
PS: This query will be perform on a dataset, that means that I can't use cursor.
Thanks

Hello,
I have something i called a deletelist, inside this list is items that is waiting to be deleted.
The deletelist looks like this:username nvarchar(20),itemtype int,deletedate datetime
The SP that runs once everyday and deletes post is called Data_DeleteFromDeleteList.
Inside of this SP i have afew delete functions like this one:DELETE FROM reg_user WHERE (username = (SELECT username FROM data_deletelist WHERE (deletedate < getdate() AND itemtype = 0)))
Now i want to add a new delete function to this list, this function is to execute a SP when the itemtype occurs, like this:SELECT EXEC [dbo].[Data_CompletlyDeleteAUser] @UserName = username, @QResult = @QResult OUTPUT FROM data_deletelist WHERE (username = (SELECT username FROM data_deletelist WHERE (deletedate < getdate() AND itemtype = 2)))
any idea of how i can rewrite this function so it works??in this SP im not using the @QResult for anything, thats in another SP
At the end of this SP, i just delete all the old records from the deletelist like this,
DELETE FROM data_deletelist WHERE (deletedate < getdate())
I am currently using the code below to convert data collected in 1 minute intervals to other time intervals (e.g., 5 minute intervals). The code works fine except for one thing. I would like the DateTime value in the new interval to coincide with the end DateTime value of that interval rather than the ceiling DateTime value (the values of Field1 thru Field4 must be extracted from existing data). The problem occurs when there is no data for a particular 1 minute time period. An example might make this more clear (in this case 1 min data is converted to 5 min data).
'2007-09-30T08:01:00'
'2007-09-30T08:02:00'
'2007-09-30T08:03:00'
'2007-09-30T08:04:00'
'2007-09-30T08:05:00'
Above values are used to create a 5 min interval record with
DateTimeValue for this record (in DestTableName) = '2007-09-30T08:05:00'
That's how it should work. However, missing data causes a problem
in the next 5 min time interval.
'2007-09-30T08:06:00'
'2007-09-30T08:07:00'
'2007-09-30T08:08:00'
'2007-09-30T08:09:00'
Missing value at '2007-09-30T08:10:00'
Above values are used to create a 5 min interval record with
DateTimeValue for this record (in DestTableName) = '2007-09-30T08:09:00'
Instead, I want the DateTime value in DestTableName to be '2007-09-30T08:10:00'
The values in Field1 - Field4 in DestTable have to be drawn from existing data; the only 'artificial' data would be the DateTime time value needed to coincide with the time interval.

How can I calculate a DateTime column by merging values from a Date column and only the time part of a DateTime column?
View 5 Replies View RelatedI'm trying to create a report which will give me a break down of how many unique vehicles have been seen between two dates via a 15 minute interval and what Lane they were seen. My current script looks like this
SELECT l.Name [Name], count(l.Name) Total, p.Created
FROM PlateReads p
inner join Lanes l on p.Lane_ID = l.ID
where LicencePlate in (Select Plate from LPRnet_MelAir_C.dbo.TempVehiclePlates)

Name being the Lane they were in and the Total being the amount of times a unique vehicle has been seen and p.Created being the date they were seen (thats what I need the interval powered off)

Hi,
I'm inserting a datetime values into sql server 2000 from c#
SQL server table details
Table nameate_test

No int
date_t DateTime
C# coding
SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI");

DataTable dt1 = new DataTable();
dt1.Columns.Add("no",typeof(System.Int16));
dt1.Columns.Add("date_t", typeof(System.DateTime));
DataRow dr = dt1.NewRow();
dr["no"] = 1;
dr["date_t"] = DateTime.Now;
dt1.Rows.Add(dr);
for(int i=0;i<dt1.Rows.Count;i++)
{
string str=dt1.Rows["no"].ToString();
DateTime dt=(DateTime)dt1.Rows["date_t"];
string insertQuery = "insert into date_test values(" + str + ",'" + dt + "')";
SqlCommand cmd = new SqlCommand(insertQuery, connectionToDatabase);
cmd.ExecuteNonQuery();
MessageBox.Show("saved");
}
When I run the above code, data is inserted into the table
The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column.
Is there any conversion needed for millisecond values?

I need to compare the contents of a column.
I have a table with 1 column. Below are the sample contents..
DateInterval
2012-06-01 00:30:00.000
2012-06-01 01:00:00.000
2012-06-01 01:30:00.000
2012-06-01 02:00:00.000
2012-06-01 02:30:00.000
[code]....
as you can see, the records have a 30minutes time interval. i need to create a query to know if there are missing records in the table. so basically the result should be this:
DateInterval
2012-06-01 18:00:00.000
2012-06-01 20:30:00.000
if it is not doable, we can get the nearest record of all missing records like this:
DateInterval
2012-06-01 17:30:00.000
2012-06-01 20:00:00.000
or this:
DateInterval
2012-06-01 18:30:00.000
2012-06-01 21:00:00.000
or this:
DateInterval
2012-06-01 17:30:00.000
2012-06-01 18:30:00.000
2012-06-01 20:00:00.000

View 3 Replies View RelatedHi All,I faced this strange problem with sql server. I have datetime column and storing value from asp.net. If the user doesnt enter any date, then we dont want any value to be stored in the database. But when we checked SQL Server, it default takes this value "01/01/1900". When users clicks on edit button, this value is fetched from database and stored in front end. I dont want this value to be stored in database if i didnt provide value. But in 1 particular page, there are 5 different date columns. I am not sure about how to go ahead. I tried the following way, but again ended up with same problem.insert into tablename.......values (...., txtFromDate.text, txtToDate.text,....). Since value is not there, '' is sent to database and above said value is stored. i want NULL to be stored in teh database when user didnt specify any value.i didnt encounter this problem in Oracle.appreciate your reply.
View 9 Replies View Relatedhi, i was wondering how to set default value in the datetime column of the database so that it will enter current date and time if one is not provided when a row is populated. is there a store procedure to do this? or built-in function?

Hi Guys,
I have to take only time from DateTime column filed value.
Is there any function in SQL Server which will give us time only.
Thanks,

I've got have a populated table and I want to convert a datetime column so it lists the date only (without the time component)
I tried to run this as a script, but returns an error:
update <table>
where <column>=convert(datetime,convert(char10),<column>,101))
When I run only this part, it does strip the date of the time component but it becomes a string, and I need this field stored as a datetime field:
convert(char(10),hire_date,101)
I'd appreciate any suggestions :)
I'm trying to update a datetime column from another datetime column. However, I just want the date transferred to the new column without the time. Any ideas? Thanks for your help.

I'm having a hard time getting one of my tables to use a non clustered index that I have on a DateTime column.
A sample version of the table is something like this
CREATE TABLE Appointments
(
ID INT NOT NULL,
AppointmentDate DateTime NOT NULL
)
with a clustered primary key on ID and a nonclustered key on AppointmentDate.
This production table has over 1million rows and the problem I have is this:
If I do a SELECT * FROM Appointments where AppointmentDate >= '20060701' AND AppointmentDate < '20060702' the Non clustered index on the AppointmentDate column works fine. i.e. I'm returning all appointments for the 1st of July.
Now if I run the exact same query using datetime parameters, a Clustered index scan is performed instead of an index seek.
DECLARE @AppDate DateTime
SET @AppDate = '20060701'
SELECT * FROM Appointments WHERE AppointmentDate >= @AppDate and AppointmentDate < DATEADD(day, 1, @AppDate)
Any ideas why it would do this?
HI friends,
Using SmallDateTime in SQL Table, how can I enforce M/DD/YY format on column of type smalldatetime in SQL ServerDB.
What happening is that SQL convert this to YYYY-MM-DD, when my DTS package brings data to table?

Hello.
In SQL server 2000 (or 2005) I have a need to query a table for rows with the max date value in a datetime column.
Currently I coded the following to give me a specific date in the column:
...where R.start_time >= '02/15/2008' and R.start_time < DateAdd(day, 1, '02/15/2008')
This gives me the rows with the exact date of 02/15/2008.
So, if I don't want to hard-code the date or pass it as a parameter how can I always get the maximum date back from the query?
Thanks.
