Detailed Description

template<typename... Types>
class Fastcgipp::SQL::Parameters< Types >

A tuple of parameters to tie to a SQL query.

This class allows you to pass separate parameters to a SQL query. From the interface perspective this should behave exactly like an std::tuple<Types...>. The differences from std::tuple lie in it's ability to format the tuple data in a way SQL wants to see it.

Template Parameters

Types

Pack of types to contain in the tuple.

Member Function Documentation

build()

void Fastcgipp::SQL::Parameters_base::build ( )

inherited

Initialize the arrays needed by SQL.

Here is the call graph for this function:

build_impl() [1/3]

template<typename... Types>

void Fastcgipp::SQL::Parameters< Types >::build_impl ( )

privatevirtual

Template side virtual to populate the above arrays.

This just gets called by build().

Implements Fastcgipp::SQL::Parameters_base.

Definition at line 466 of file parameters.hpp.

build_impl() [2/3]

template<typename... Types>

template<size_t column>

void Fastcgipp::SQL::Parameters< Types >::build_impl ( std::index_sequence< column >  )

inlineprivate

Terminating template SQL array building function.

Definition at line 468 of file parameters.hpp.

build_impl() [3/3]

template<typename... Types>

template<size_t column, size_t... columns>

void Fastcgipp::SQL::Parameters< Types >::build_impl ( std::index_sequence< column, columns... >  )

inlineprivate

Recursive template SQL array building function.

Definition at line 459 of file parameters.hpp.

formats()

const int* Fastcgipp::SQL::Parameters_base::formats ( ) const

inlineinherited

Constant pointer to array of all formats.

Definition at line 420 of file parameters.hpp.

oids()

const unsigned* Fastcgipp::SQL::Parameters_base::oids ( ) const

inlineinherited

Constant pointer to array of all parameter oids.

This is not valid until build() is called

Definition at line 399 of file parameters.hpp.

raws()

const char* const* Fastcgipp::SQL::Parameters_base::raws ( ) const

inlineinherited

Constant pointer to pointer array of all raw parameter data.

This is not valid until build() is called

Definition at line 408 of file parameters.hpp.

size()

template<typename... Types>

constexpr int Fastcgipp::SQL::Parameters< Types >::size ( ) const

inlineconstexprprivatevirtual

How many items in the tuple?

Implements Fastcgipp::SQL::Parameters_base.

Definition at line 452 of file parameters.hpp.

sizes()

const int* Fastcgipp::SQL::Parameters_base::sizes ( ) const

inlineinherited

Constant pointer to array of all parameter sizes.

Definition at line 414 of file parameters.hpp.

Member Data Documentation

m_formats

const std::vector<int>* Fastcgipp::SQL::Parameters_base::m_formats

protectedinherited

Array of formats for each parameter.

This gets initialized by calling build(). It is really just an array of 1s.

Definition at line 383 of file parameters.hpp.

m_oids

const std::vector<unsigned>* Fastcgipp::SQL::Parameters_base::m_oids

protectedinherited

Array of oids for each parameter.

This gets initialized by calling build().

Definition at line 364 of file parameters.hpp.

m_raws

std::vector<const char*> Fastcgipp::SQL::Parameters_base::m_raws

protectedinherited

Array of raw data pointers for each parameter.

This gets initialized by calling build().

Definition at line 370 of file parameters.hpp.

Referenced by Fastcgipp::SQL::Parameters_base::build().

m_sizes

std::vector<int> Fastcgipp::SQL::Parameters_base::m_sizes

protectedinherited

Array of sizes for each parameter.

This gets initialized by calling build().

s_formats

template<typename... Types>

const std::vector< int > Fastcgipp::SQL::Parameters< Types >::s_formats

staticprivate

Definition at line 449 of file parameters.hpp.

s_oids

template<typename... Types>

const std::vector< unsigned > Fastcgipp::SQL::Parameters< Types >::s_oids

staticprivate

Initial value:

{
    Fastcgipp::SQL::Parameter<Types>::oid...
}
