m_field_typecode

template<class Typecode_tp , Typecode_tp typecode_end_tp>

Typecode_t Field_view_definition< Typecode_tp, typecode_end_tp >::m_field_typecode

Enum value for the mysql::abi_helpers::Field object holding the value.

m_null_typecode

template<class Typecode_tp , Typecode_tp typecode_end_tp>

Typecode_t Field_view_definition< Typecode_tp, typecode_end_tp >::m_null_typecode {typecode_end_tp}

Enum value for a mysql::abi_helpers::Field object that holds a bool indicating if the value is NULL.

Note

: this is only a remainder of a legacy protocol: new protocols should just omit m_field_typecode from the packet to indicate that the field is NULL, and their Field_view_definitions should leave this field with the default value.

m_type

template<class Typecode_tp , Typecode_tp typecode_end_tp>

Column_type Field_view_definition< Typecode_tp, typecode_end_tp >::m_type

Type of the field.

typecode_end

template<class Typecode_tp , Typecode_tp typecode_end_tp>

constexpr Typecode_t Field_view_definition< Typecode_tp, typecode_end_tp >::typecode_end = typecode_end_tp
