Can you provide an example?I think I know what you're trying to say, though. Like this?
SELECT NULLIF(CAST('1/1/1900' AS datetime),'')
Even though this thread is 6 years old...
What is your question here? Not sure what you are trying to do there but the NULLIF is kind of pointless. The issue here is about implicit conversion. An empty string when cast to a datetime will convert to 1/1/1900.
To demonstrate you can reverse your dates here and it will still return NULL.
SELECT NULLIF(CAST('' AS datetime), '1/1/1900')
