Function Documentation

create_vector() [1/2]

template<class Container >

void mysqlpp::create_vector	(	const Container &	c,
		std::vector< bool > &	v,
		std::string	s0,
		std::string	s1,
		std::string	s2,
		std::string	s3,
		std::string	s4,
		std::string	s5,
		std::string	s6,
		std::string	s7,
		std::string	s8,
		std::string	s9,
		std::string	sa,
		std::string	sb,
		std::string	sc
	)

Create a vector of bool using a list of named fields.

This function is used with the ResUse and Result containers, which have a field_num() member function that maps a field name to its position number. So for each named field, we set the bool in the vector at the corresponding position to true.

This function is used within the library to build the vector used in calling the vector form of Row::equal_list(), Row::value_list(), and Row::field_list(). See the "Harnessing SSQLS Internals" section of the user manual to see that feature at work.

create_vector() [2/2]

void mysqlpp::create_vector	(	size_t	size,
		std::vector< bool > &	v,
		bool	t0,
		bool	t1 = false,
		bool	t2 = false,
		bool	t3 = false,
		bool	t4 = false,
		bool	t5 = false,
		bool	t6 = false,
		bool	t7 = false,
		bool	t8 = false,
		bool	t9 = false,
		bool	ta = false,
		bool	tb = false,
		bool	tc = false
	)

Create a vector of bool with the given arguments as values.

This function takes up to 13 bools, with the size parameter controlling the actual number of parameters we pay attention to.

This function is used within the library to build the vector used in calling the vector form of Row::equal_list(), Row::value_list(), and Row::field_list(). See the "Harnessing SSQLS Internals" section of the user manual to see that feature at work.

equal_list() [1/7]

template<class Seq1 , class Seq2 >

equal_list_b<Seq1, Seq2, do_nothing_type0> mysqlpp::equal_list	(	const Seq1 &	s1,
		const Seq2 &	s2,
		bool	t0,
		bool	t1 = false,
		bool	t2 = false,
		bool	t3 = false,
		bool	t4 = false,
		bool	t5 = false,
		bool	t6 = false,
		bool	t7 = false,
		bool	t8 = false,
		bool	t9 = false,
		bool	ta = false,
		bool	tb = false,
		bool	tc = false
	)

Constructs a equal_list_b (sparse equal list)

Same as equal_list(Seq&, Seq&, const char*, bool, bool...) except that it doesn't take the const char* argument. It uses a comma for the delimiter. This form is useful for building simple equals lists, where no manipulators are necessary, and the default delimiter and equals symbol are suitable.

References mysqlpp::do_nothing, and mysqlpp::equal_list().

equal_list() [2/7]

template<class Seq1 , class Seq2 >

equal_list_b<Seq1, Seq2, do_nothing_type0> mysqlpp::equal_list	(	const Seq1 &	s1,
		const Seq2 &	s2,
		const char *	d,
		bool	t0,
		bool	t1 = false,
		bool	t2 = false,
		bool	t3 = false,
		bool	t4 = false,
		bool	t5 = false,
		bool	t6 = false,
		bool	t7 = false,
		bool	t8 = false,
		bool	t9 = false,
		bool	ta = false,
		bool	tb = false,
		bool	tc = false
	)

Constructs a equal_list_b (sparse equal list)

Same as equal_list(Seq&, Seq&, const char*, const char*, bool, bool...) except that it doesn't take the second const char* argument. It uses " = " for the equals symbol.

References mysqlpp::do_nothing, and mysqlpp::equal_list().

equal_list() [3/7]

template<class Seq1 , class Seq2 >

equal_list_b<Seq1, Seq2, do_nothing_type0> mysqlpp::equal_list	(	const Seq1 &	s1,
		const Seq2 &	s2,
		const char *	d,
		const char *	e,
		bool	t0,
		bool	t1 = false,
		bool	t2 = false,
		bool	t3 = false,
		bool	t4 = false,
		bool	t5 = false,
		bool	t6 = false,
		bool	t7 = false,
		bool	t8 = false,
		bool	t9 = false,
		bool	ta = false,
		bool	tb = false,
		bool	tc = false
	)

Constructs a equal_list_b (sparse equal list)

Same as equal_list(Seq&, Seq&, const char*, const char*, Manip, bool, bool...) except that it doesn't take the Manip argument. It uses the do_nothing manipulator instead, meaning that none of the elements are escaped when being inserted into a stream.

References mysqlpp::do_nothing, and mysqlpp::equal_list().

equal_list() [4/7]

template<class Seq1 , class Seq2 , class Manip >

equal_list_ba<Seq1, Seq2, Manip> mysqlpp::equal_list	(	const Seq1 &	s1,
		const Seq2 &	s2,
		const char *	d,
		const char *	e,
		Manip	m
	)

Constructs an equal_list_ba.

Same as equal_list(Seq&, Seq&, const char*, const char*) except that it also lets you specify the manipulator. Use this version if the data must be escaped or quoted when being inserted into a stream.

References mysqlpp::equal_list().

equal_list() [5/7]

template<class Seq1 , class Seq2 , class Manip >

equal_list_b<Seq1, Seq2, Manip> mysqlpp::equal_list	(	const Seq1 &	s1,
		const Seq2 &	s2,
		const char *	d,
		const char *	e,
		Manip	m,
		bool	t0,
		bool	t1 = false,
		bool	t2 = false,
		bool	t3 = false,
		bool	t4 = false,
		bool	t5 = false,
		bool	t6 = false,
		bool	t7 = false,
		bool	t8 = false,
		bool	t9 = false,
		bool	ta = false,
		bool	tb = false,
		bool	tc = false
	)

Constructs a equal_list_b (sparse equal list)

Same as equal_list(Seq&, Seq&, const char*, const char*, Manip, vector<bool>&) except that it takes boolean parameters instead of a list of bools.

References mysqlpp::equal_list().

equal_list() [6/7]

template<class Seq1 , class Seq2 , class Manip >

equal_list_b<Seq1, Seq2, Manip> mysqlpp::equal_list	(	const Seq1 &	s1,
		const Seq2 &	s2,
		const char *	d,
		const char *	e,
		Manip	m,
		const std::vector< bool > &	vb
	)

Constructs a equal_list_b (sparse equal list)

Same as equal_list(Seq&, Seq&, const char*, const char*, Manip) except that you can pass a vector of bools. For each true item in that list, operator<< adds the corresponding item is put in the equal list. This lets you pass in sequences when you don't want all of the elements to be inserted into a stream.

References mysqlpp::equal_list().

equal_list() [7/7]

template<class Seq1 , class Seq2 >

equal_list_ba<Seq1, Seq2, do_nothing_type0> mysqlpp::equal_list	(	const Seq1 &	s1,
		const Seq2 &	s2,
		const char *	d = ",",
		const char *	e = " = "
	)

Constructs an equal_list_ba.

This function returns an equal list that uses the 'do_nothing' manipulator. That is, the items are not quoted or escaped in any way when inserted into a stream. See equal_list(Seq, Seq, const char*, const char*, Manip) if you need a different manipulator.

The idea is for both lists to be of equal length because corresponding elements from each list are handled as pairs, but if one list is shorter than the other, the generated list will have that many elements.

Parameters

s1	items on the left side of the equals sign when the equal list is inserted into a stream
s2	items on the right side of the equals sign
d	delimiter operator<< should place between pairs
e	what operator<< should place between items in each pair; by default, an equals sign, as that is the primary use for this mechanism.

operator<<() [1/4]

template<class Seq1 , class Seq2 , class Manip >

std::ostream& mysqlpp::operator<<	(	std::ostream &	o,
		const equal_list_b< Seq1, Seq2, Manip > &	el
	)

Same as operator<< for equal_list_ba, plus the option to suppress insertion of some list items in the stream.

See equal_list_b's documentation for examples of how this works.

operator<<() [2/4]

template<class Seq1 , class Seq2 , class Manip >

std::ostream& mysqlpp::operator<<	(	std::ostream &	o,
		const equal_list_ba< Seq1, Seq2, Manip > &	el
	)

Inserts an equal_list_ba into an std::ostream.

Given two lists (a, b) and (c, d), a delimiter D, and an equals symbol E, this operator will insert "aEcDbEd" into the stream.

See equal_list_ba's documentation for concrete examples.

operator<<() [3/4]

template<class Seq , class Manip >

std::ostream& mysqlpp::operator<<	(	std::ostream &	o,
		const value_list_b< Seq, Manip > &	cl

template<class Seq , class Manip >

std::ostream& mysqlpp::operator<<	(	std::ostream &	o,
		const value_list_ba< Seq, Manip > &	cl
	)

Inserts a value_list_ba into an std::ostream.

		bool	t7 = false,
		bool	t8 = false,

		bool	ta = false,
		bool	tb = false,
		bool	tc = false
	)

Constructs a sparse value list.

Same as value_list(Seq&, const char*, Manip, bool, bool...) but without the Manip or delimiter parameters. We use the do_nothing manipulator, meaning that the value list items are neither escaped nor quoted when being inserted into a stream. The delimiter is a comma. This form is suitable for lists of simple data, such as integers.

		bool	ta = false,
		bool	tb = false,
		bool	tc = false
	)

Constructs a sparse value list.

Same as value_list(Seq&, const char*, Manip, bool, bool...) but without the Manip parameter. We use the do_nothing manipulator, meaning that the value list items are neither escaped nor quoted when being inserted into a stream.
