◆ BindValue()

template<NullableValueType T>

void sqt::NullableValueTraits< T >::BindValue	(	Statement &	statement,
		int	parameter_index,
		const T &	value )

static

Binds a nullable value to the statement at the specified parameter index.

Parameters

statement	The statement to which the value is bound.
parameter_index	The index of the parameter to which the value is bound.
value	The nullable value to bind.

Exceptions

sqt::SQLError Thrown if the binding fails.

If the value is null, this method calls the BindParameter(int, std::nullopt_t) method of the statement to bind a null. Otherwise, it delegates to the BindValue() method of the corresponding sqt::PrimitiveValueTraits<> specialization to bind the underlying value.
