What is the desired datatype of the end-result? Also what is the datasource?

Space is not valid for that datatype. you could replace it with a NULL, or you could change the datatype to a character type. But space isn't going to insert into a table.

Replacing the space with a null did not work either

Ok, why don't you explain the whole process then because this trying to fix the problem we can see with the microscope isn't working..

text file comes with default date 1/1/1900 . I tried in derived column before converting in to date as [column1] =="1/1/1900" ? Null or

[column1] =="1/1/1900" ? "" before data conversion to date,

tried after data conversion to date as

[column1] =="1/1/1900" ? (DT_date) Null

does not work , either way , accomplished by using update at the end of loading in transact_ SQl but that is not our standards.

Please advice.

Why don't you try:

[column1] =="1/1/1900" ? [column1] : NULL(DT_DBTIMESTAMP)

You need to reverse the 2nd and 3rd operand.

Also, I assume that col1 is of datatype DT_STR or DT_WSTR, so you will have to do an extra cast:

col1 == "1/1/1900" ? NULL(DT_DBTIMESTAMP) : (DT_DBTIMESTAMP)col1

The output needs to be stored in a new column (of data type DT_DBTIMESTAMP.

I agree, the flip is necessary. Sorry, it was late.
