boost::sqlite::param_ref Struct Reference

A reference to a value to temporary bind for an execute statement. Most values are captures by reference. More...

#include <include/boost/sqlite/statement.hpp>

Public Member Functions
	param_ref ()=default
	Default construct a parameter, gives null.
	param_ref (blob_view blob)
	Bind a blob.
	param_ref (double value)
	Bind a floating point value.
template<typename I , typename = typename std::enable_if<std::is_integral<I>::value>::type>
	param_ref (I value)
	Bind an integer.
	param_ref (std::nullptr_t)
	Bind null.
template<typename T >
	param_ref (std::unique_ptr< T > ptr)
	Bind pointer value to the parameter.
template<typename T , typename Deleter >
	param_ref (std::unique_ptr< T, Deleter > ptr, typename std::enable_if< std::is_empty< Deleter >::value &&std::is_default_constructible< Deleter >::value, int >::type *=nullptr)
	Bind pointer value with a function custom deleter to the parameter. The deleter needs to be default constructible.
template<typename T >
	param_ref (std::unique_ptr< T, void(*)(T *)> ptr)
	Bind pointer value with a function as deleter to the parameter.
	param_ref (string_view text)
	Bind a string.
template<typename T >
	param_ref (T &&t, decltype(variant2::visit(make_visitor(), std::forward< T >(t))) *=nullptr)
	Construct param_ref from a variant.
	param_ref (variant2::monostate)
	Bind null.
	param_ref (zero_blob zb)
	Bind a zero_blob value, i.e. a blob that initialized by zero.
int	apply (sqlite3_stmt *stmt, int c) const
	Apply the param_ref to a statement.
