In SSIS expression how can we store only date from getdate()

I want to store the date from the getdate()-1 in SSIS variables.

Something like when we run the sql query 

select CONVERT(varchar(10),getdate()-1,120)

Output - 2017-11-10

I tried the below query in the expression.

@[User::Dates]  =  
           (DT_WSTR,4)YEAR(GETDATE())  
+ RIGHT ( "0" + (DT_WSTR,2)MONTH(GETDATE()),2) 
+ RIGHT ( "0" + (DT_WSTR,2)DAY(GETDATE()),2)

And it gives me the output as

20171111

Can someone tell me what will the expression for the variable. My datatype for variable is string

Solution

You can simply use the following expression to achieve this:

 SUBSTRING( (DT_STR,50, 1256)DATEADD("DAY",-1,GETDATE()) , 1, 10)

It will return only date with the following format 2017-11-11 (yesterday date)

Explanation

According to this Microsoft Document

When a string is cast to a DT_DATE, or vice versa, the locale of the transformation is used. However, the date is in the ISO format of YYYY-MM-DD, regardless of whether the locale preference uses the ISO format

Side Note: Other methods may work, but there is a problem when using datepart functions (DATEPART, YEAR, MONTH, DAY) if the day or month is less than 10 you may have another date format (i.e. 2017-1-3 -> yyyy-M-d or 2017-10-1 -> yyyy-MM-d). So you have to use Them with other methods to fix that (i.e. RIGHT("0" + (DT_STR,50,1256)DAY([Column0]),2))

You're almost there.

First, you need to add the dashes (simple string concatenation).

Second, the syntax for getting the previous day is slightly more complex: SSIS doesn't support GETDATE() - 1, so you need DATEADD("DAY", -1, GETDATE()).

Here's what you're looking for:

(DT_WSTR, 4) YEAR(DATEADD("DAY", -1, GETDATE()))
+ "-"
+ RIGHT("0" + (DT_WSTR, 2) MONTH(DATEADD("DAY", -1, GETDATE())), 2) 
+ "-"
+ RIGHT("0" + (DT_WSTR, 2) DAY(DATEADD("DAY", -1, GETDATE())),2)
