Detailed Description

template<typename T>
struct pqxx::nullness< T, std::enable_if_t< std::is_arithmetic_v< T > > >

The built-in arithmetic types do not have inherent null values.

Not-a-Number values (or NaNs for short) behave a lot like an SQL null, but they are not nulls. A non-null SQL float can be NaN.

The documentation for this struct was generated from the following file:
