I want to replace 0’s in mysql table with ‘NULL’. I have read that querying the following way would replace ‘NULL’ with 0

SELECT COALESCE(null_column, 0) AS null_column FROM whatever;

But how to the other way?

    You can use NULLIF, which will return NULL if the value in the first parameter matches the value in the second parameter.

    SELECT NULLIF(null_column, 0) AS null_column FROM whatever
