Select a nullable bit with a default value

I need to select a nullable bit column in a view, but use a default value of FALSE whenever the value is NULL. (For other reasons, I can't add the default value on the source table itself.) Here is what I am doing. 

CAST 
(
    CASE 
    WHEN bit_column IS NULL THEN 0 
    ELSE bit_column  
END 
    AS BIT
) AS bit_column,
...

I have to do this on four columns, so I'm wondering if there is a better/more efficient way to do this.

Solution

  • use the isnull function.

    isnull(bit_column, 0)
