data type which contains both test and number

Hi,

Just curious to know if there is a way to store both number and text in one column.

Actually I want to apply a formula something like this:

if(number), return some value, ""

So if in one column I have both text and number than I can apply  isnumber furmula and get the result.

However if I convert entire column in text OR number than I can not use this formula to get the desired result.

Note: I saw one of my column is having "any" data type when I see in transform tab in query editor mode but I dont get this option as a drop down.

Thanks.
