Hi,
I am trying to access a date column up to millisecond precession. So I cast date to as follows:
Code BlockCONVERT(varchar(23),CREATE_DATE,121)
I get millisecond part as a result of query but its 000?.

When I try to test the format by using getDate instead of DateTime column I get right milliseconds.
CONVERT(varchar(23),GetDate(),121) --Gives right milliseconds in return

Hi,
I tried entering this value "8/24/2006 1:35:00.127 PM" with 127 as the milliseconds in a datetime field, but encountered error saying inconsistent datatype ...
Anyone knows how to store datetime value with milliseconds in the SQL database?
Thanks

I want to execute a paramterized ADO insert command into a SQL Server DATETIME column without losing the milliseconds. I can accomplish this without parameters, but that isn't what I want. Any suggestions?
It is OK that DATETIME only has a resolution of 3.33 milliseconds.
See the attached code:

I'm running into a constant issue of SQL Server modifying themillisecond part of a timestamp insert from another application. Theapplication inserts timestamp which includes a millisecond portion as astring (varchar). But when an SQL Server moves this data to anothertable (for reporting), the string is inserted in a datetime field, themillisecond field invariably changes by 1-2 milliseconds for everysingle data point inserted. Given the time critical nature of this data(to a millisecond), its almost impossible to avoid this other than toleave the data as string type. But this drives the analytical reportingfolks wild as report queries based on time criteria are getting messedup. Any ideas how to force SQL Server not to mess around with themillisecond value? Does this problem exist with SQL Server 2005 as well?

I need to set a variable to datetime and time to exact milliseconds in SQL server in stored procedure.
Example:
set MyUniqueNumber = 20071101190708733
ie. MyUniqueNumber contains yyyymmddhhminsecms
Please help, i tried the following:
1. SELECT CURRENT_TIMESTAMP; ////// shows up with - & : , I want single string as in above example.2.
select cast(datepart(YYYY,getdate()) as varchar(4))+cast(datepart(mm,getdate()) as char(2))+convert(varchar(2),datepart(dd,getdate()),101 )+cast(datepart(hh,getdate()) as char(2))+cast(datepart(mi,getdate()) as char(2))+cast(datepart(ss,getdate()) as char(2))+cast(datepart(ms,getdate()) as char(4))
This one doesnot display day correctly, it should show 01 but shows 1

Hi,
I'm inserting a datetime values into sql server 2000 from c#
SQL server table details
Table nameate_test
columnname datatype
No int
date_t DateTime
C# coding
SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI");
connectionToDatabase.Open();
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?
thanks,
Mani

Hi,
i am trying to add milliseconds to a time. For example if i have a time of 01:01:05:000 and i want to add 0.297 milliseconds to it i use the following simplified query
SELECT CONVERT(nvarchar(20), DATEADD(ms, 0.297, '00:01:05:000'), 14) AS Expr1
However instead of getting 01:01:05:0.297 i get 01:01:05:000. Can somebody please tell me what i am doing wrong.

Hi!
I have the difference between two dates in milliseconds. I want to convert this difference to the format hh:mm:ss.mmm, without the date. So, if the difference is bigger then one day, I would like to show it like this, for example: 36:25:14.047
How can I do this?
Thank you!

I've been working on a project to ensure that accross our entire data warehouse everything is at the same accuracy level as far as time - migrating everything to use the full hh:mis.mmm. Some places were using hh:mis:mmm (colon instead of decimal point) and many places not using milliseconds.
The SQL server portion went essentially without issue - however SSIS is not cooperating. For example I have data I am importing from a file that is in format: hh:mis (no milliseconds) that I need to compare to data from SQL (now containing full milliseconds) - matching on time ranges. Previously this was done by converting both to the "database time" datatype in SSIS and comparing. Now when converting the cTime to database time SSIS fails and complains "The value could not be converted because of a potential loss of data".
I don't want to lop off the milliseconds becuase that could create rounding errors.
I don't like it but the only option I can think of is keeping everything in string and comparing the strings... then I run into the issue of making sure to convert all sources of data into the exact same hh:mis:mmm format in text.
Is there an easier way? I know some people use "milliseconds since midnight" and so forth but that would require major reworking of the data warehouse and many packages.

I am writing a report that Queries a SQL DB using 'SQL Server Business Intelligence Development Studio'. I have a field in the DB called duration and it is in milliseconds. I am trying to find an easy way to convert the format from Milliseconds to HH:MM:SS.Nearest I can get is the following for the field:
=Int( ((Fields! DURATION.Value/1000) / 60) / 60) & ":" & Int(((((Fields!DURATION.Value/1000) / 60) / 60) - Int(((Fields!DURATION.Value/1000) / 60) / 60)) * 60)
The output is in HH:MM. One issue with this is if the MM is say :03, it prints as :3. I lose the leading 0 so 9:03 (9hrs and 3 minutes) prints as 9:3. Where as 9:30 (9 hrs and 30 minutes) prints as 9:30 as it should.

Hi 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.

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 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?

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.
