So far I’m doing it this way:

SELECT * FROM table_name WHERE column in(var1,var2,var3) or column is NULL

I have issues with repeating column name two times here since in() can’t take null as an argument, it returns also no error, just 0 columns. (Maybe some magic variables that can refer last called column ?)

    This:

    'column'

    is a string literal, not a column name. So this:

    'column' in(var1,var2,var3) or 'column' is NULL

    won’t match anything unless var1, var2, or var3 happen to be the string 'column'. Try dropping the quotes on the column name:

    SELECT * FROM table_name WHERE column in (var1, var2, var3) or column is NULL
