SQLite equivalent to ISNULL(), NVL(), IFNULL() or COALESCE()

Question

I\'d like to avoid having many checks like the following in my code:

myObj.someStringField = rdr.IsDBNull(someOrdinal) 
                            ? string.         


        

Answer 1

You can easily define such function and use it then:

ifnull <- function(x,y) {
  if(is.na(x)==TRUE) 
    return (y)
  else 
    return (x);
}

or same minified version:

ifnull <- function(x,y) {if(is.na(x)==TRUE) return (y) else return (x);}
