If Statement with two different data types

In the data set I have a column for delivery date. If there is no delivery date the source of the data enters "1/1/1900". I am trying to create a second column that leaves the cells blank if this date exists. The problem I am having is that it won't except IF statements referencing two different data types (date and text).  Is there away around using two different data types in an IF statement?  The forumla is below. Thanks in advance for your help.

 

 

 

 

DeliveryDate = if('Total Trans'[Delivery Date]="1/1/1900","",'Total Trans'[Delivery Date])

I found that the solution is to go under "OPTIONS">Data Load, and uncheck "Automatically detect column types and headers for unstructured sources".  This automatically converts everything to text and allows you to select the data type for each column.

Thanks for the tip. I am fairly new to this and getting adjusted to the nuances of this tool.

The easiest option would be to use the Replace Values button in the Query editor instead of creating a new column. Replace 1/1/1900 with null. Literally type the word null into the box.

 

Anyway if you want to do this as a new DAX column, you need to use DAX rules. You've written an Excel formula. By putting the date in quotation marks and using "" to denote a blank return value, you're treating treating those two things as text rather than dates. You need to use the BLANK() and DATE() formulas.

 

DeliveryDate = IF(
	'Total Trans'[Delivery Date] = DATE(1900, 1, 1),
	BLANK(),
	'Total Trans'[Delivery Date]
)

Just a reminder although it DOES NOT apply to this question since this is only a comparison NOT a date calculation

 

the first officially supported date in DAX is March 1, 1900 (for date calculations)

hi @cheid1977

 

Try with

 

DeliveryDate = if('Total Trans'[Delivery Date]="1/1/1900",blank(),'Total Trans'[Delivery Date])

Thanks for responding. Now I get the below error message.

 

A single value for column 'Delivery Date' in table 'Total Trans' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.

Are you creating a measure or a calculated column?

 

This is with a calculated column
