I want to create a column that returns '1' if it exists in the data record, and '0' if does not

[penelopevit]

Well, 

If there is a "sale date" recorded for each Lead, I want the value '1' to be returned. If the sales date record does not exist, I want the value '0' to be returned.

I tried it with the following function:

Negócio Fechado =

IF(
ISBLANK('hs_date_entered_13864390')
"1";
"0"
)

...but it's does not work. Well, maybe it's because of the "if" doesn't accept 'date'?

Are there any date functions I could use to check if the date stamp exists and return "1" to me? Help me!!!!!!!!!!!!

And please use correct data types for whatever you do. "1" is a string, not a number. 

And here's an excerpt from the above dax.guide with some very important and relavant to your case information:
