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

For the equivalent of NVL() and ISNULL() use:

IFNULL(column, altValue)

column : The column you are evaluating.

altValue : The value you want to return if 'column' is null.

Example:

SELECT IFNULL(middle_name, 'N/A') FROM person;

*Note: The COALESCE() function works the same as it does for other databases.
