How do I strip the date off of a datetime string in SQL SSIS?
I would just do a cast to DT_DBTIME
type (using Derived Column transform, or Convert type transform). DT_DBTIME
contains just (hours, minutes, seconds) part of the date/time, so you'll get rid of the date part.
How to remove from DateTime variable hours, minutes, seconds and other parts in SSIS
You can achieve that using a derived column:
(DT_DBTIMESTAMP)(DT_DBDATE)@[User::DateTimeVariable]
Casting to DT_DBDATE
will remove the time part, then recasting to DT_DBTIMESTAMP
will re-add a time part but with 12:00 AM
value = 00:00:00
Example:
Removing time from datetime in SQL Server
If just want store date part try altering that column data type and make it as just date
ALTER TABLE dbo.Time ALTER COLUMN PK_Date Date
DateTime Conversion to Date
Stripping the time was discussed here. Could you possibly use a similar method?

Refer BOL --> Convert
print convert(varchar(10),getdate(),101)
print convert(varchar(10),DateTimeCol,101)

SSIS expression: convert date to string
For SSIS you could go with:
RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE())

A way to extract from a DateTime value data without seconds
For a solution that truncates using strings try this:
SELECT CAST(CONVERT(CHAR(16), GetDate(),20) AS datetime)
CHAR(16) works only if our variable is converted to ODBC canonical format, as shown above by using 20
as the format specifier.
DECLARE @date DateTime = '2011 Nov 22 12:14:55';
SELECT CONVERT(Char(16), @date ,20) AS datetime
Results:
| datetime |
|------------------|
| 2011-11-22 12:14 |
Then you simply cast back to a DateTime type to continue using the value.
NOTE: This is only viable for data types that do not carry TimeZone info.
Also type conversions to VarChar and back are usually LESS performant than using DateTime functions that use numeric operations internally.Consider other solutions posted if performance is a concern or if you must retain timezone information.
T-SQL SSIS Export DateTime type to Date Time
It appears you need dates and times exported in a particular format. While you're coercing them to the correct representation in your select statement, it is crucial that the metadata the pipeline receives is that the data is typed as a string DT_STR/DT_WSTR.
If the first time those columns were presented to the pipeline they were a date or time type, then SSIS may have kept the metadata and is implicitly converting back to a datetime type. Double clicking the pipeline between the source and destination will show what the types are.
The same holds true for your Flat File Format connection manager. Here, you want to have the date and time columns specified as string because while it contains date and time data, you have a specific format in mind so leave it as a string of the correct length (and unicode-ness).
SSIS change datetime variable to other format
The safest bet is to convert your DateTime variable into the ISO date format:
"'" + (DT_WSTR,4)YEAR(@[User::InputDateV])
+ RIGHT("0" + (DT_WSTR,2)MONTH(@[User::InputDateV]),2)
+ RIGHT("0" + (DT_WSTR,2)DAY(@[User::InputDateV]),2)
+ "'"
This evaluates to '20121024' and as such is a perfect, unambiguous date string for SQL Server.
SQL Server remove milliseconds from datetime
You just have to figure out the millisecond part of the date and subtract it out before comparison, like this:
select *
from table
where DATEADD(ms, -DATEPART(ms, date), date) > '2010-07-20 03:21:52'
