Passing NULL-value into package variables

We have a package with a package variable.
This variable is of data-type 'DateTime'.
However, when i try to pass the value 'NULL' the package fails... i use the following statement with 'dtexec.exe'

/SET \Package.Variables[MyDate].Value;"NULL"

What's the correct syntax for passing null-values? But maybe (because i cannot find anything on this) i should ask if this is even possible...

I don't think you can pass nulls through the commandline dtexec or dtexecui simply because a DBNull is an object. One option you can pursue is to pass it using a console app written in VB or C#.

This link shows one of the ways of doing that.|||

Its not possible.

One way around it may be to have a boolean variable called IsDatetimeNull which you set to TRUE or FALSE from the command-line.

Then, you put an expression on your datetime variable which sets it to NULL(DT_DBTIMESTAMP) if IsDatetimeNull==TRUE.

Something like that anyway. You get the idea.

Thanx,

To bad it cannot be done simple. But i get the idea.
Maybe i put a feature request in Connect.
