Member Function Documentation

dbi_result dbixx::row::get_dbi_result

(

)

[inline]

Get underlying libdbi object. For low level access

bool dbixx::row::isempty

(

)

Check if this row has some data or not

bool dbixx::row::isnull

(

int

inx

)

Check if the column at position indx has NULL value, first column index is 1

bool dbixx::row::isnull

(

std::string const &

id

)

Check if the column named id has NULL value

bool dbixx::row::fetch	(	int	pos,
		short &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		unsigned short &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		int &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		unsigned &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		long &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		unsigned long &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		long long &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		unsigned long long &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		float &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		double &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		long double &	value
	)

Fetch value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		std::string &	value
	)

Fetch string value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::fetch	(	int	pos,
		std::tm &	value
	)

Fetch time value at position pos (starting from 1), returns false if the column has null value.

bool dbixx::row::operator[]

(

std::string const &

id

)

[inline]

Syntactic sugar for isnull(id)

bool dbixx::row::operator[]

(

int

ind

)

[inline]

Syntactic sugar for isnull(id)

template<typename T>

row& dbixx::row::operator>>

(

T &

v

)

[inline]

Fetch a value v from the row starting with first column. Each next call updates the internal pointer to next column in row

unsigned int dbixx::row::cols

(

)

Get number of columns in the row

template<typename T>

T dbixx::row::get

(

int

col

)

[inline]

Fetch value by column. It fetches the value from column col (starting from 1) and returns it. If the column is null it throws dbixx_error
