Hi,
I'm trying to use VBScript in DTS to convert a time
string, with tenths of a second, to a sql 2k datetime
value. The standard ISO format of "yyyy/mm/dd hh:mm:ss
AM/PM" doesn't seem to support fractions of a second. Is
there a way in DTS Active-X script to assign a string
value like "2003-11-07 17:23:33.4" to a SQL datetime
column?

Thanks for any advice.

Hi Fred,

Look at the datetime definition in BOL. It is internally stored as a decimal
allowing down to 1/3 of millisecond to be stored. What you are asking for is
a mere representation of the value. T-SQL CONVERT function shows
milliseconds and in those formats milliseconds can be passed to datetime
column.

It would be nice if you could just assign the data in its original type
(most likely Variant/Date) to the destination field, but there is a
problem in the conversion of dates from datetime in ADO into Variant and
vice versa:

So, you'll have to use a string. To preserve the milliseconds, append
them to the time portion of your string in the same way that SQL Server
presents them - .nnn

Now the problem is, I don't see a way to extract the milliseconds from a
Date field in VBScript.

Your best bets are:

* forget using VBScript to transform this field, just use a DataPump
transform

* convert the data to a string type in your source database, and
possibly also your target database, and handle the conversion back to
datetime in SQL Server

If you are pulling the data from a system that doesn't allow you to
convert the field to a string, then you are possibly screwed. Either
that, or you need an interim step that operates outside DTS.

Oh, actually, there might be a way to get the milliseconds from the
source field (I'm not untyping what I just typed though!):

http://support.microsoft.com/default...EN-US;Q327080&

That code is VB, not VBScript, so might not help. Also, I'm still not
sure whether you will get away with it at the target database side; you
might need to pump the data into a table with the field in question
defined as a char field, as I think the Variant to datetime conversions
might happen within ADO.

cheers,
Ross.

Hi Fred,

Thank you for using MSDN Newsgroup! It's my pleasure to assist you with this issue.

I think that Ross has pointed out a lot on your issue and I just want to add values here:

I don't think you can get milliseconds in VBScript, as Conversion from a Variant to Date type in
VBScript always causes precision lost.

One workaround is that you can send the value back as a string instead of datetime data type,
or you can just use a Copy Column Transformation for that one'milliseconds column'.

For more information, you can also reference the following article:
