Current implementation looks consistent:

D type -- SQL type
int    -- INT NOT NULL
Int    -- INT NULL
long   -- BIGINT NOT NULL
Long   -- BIGINT NULL
string -- VARCHAR(255) NOT NULL
String -- VARCHAR(255) NULL

Uppercase types are nullable.

@NotNull/@Null annotations are not required. Nullability can be 
inferred from type name.
