Typedefs
typedef unspecified type	string
	string will be std::u16string or std::32string if NANODBC_ENABLE_UNICODE defined.
typedef unspecified type	null_type
	null_type will be int64_t for 64-bit compilations, otherwise long.
template<typename T >
using	is_string = std::integral_constant< bool, std::is_same< typename std::decay< T >::type, std::string >::value||std::is_same< typename std::decay< T >::type, wide_string >::value >
	A type trait for testing if a type is a std::basic_string compatible with the current nanodbc configuration.
template<typename T >
using	is_character = std::integral_constant< bool, std::is_same< typename std::decay< T >::type, std::string::value_type >::value||std::is_same< typename std::decay< T >::type, wide_char_t >::value >
	A type trait for testing if a type is a character compatible with the current nanodbc configuration.
template<typename T >
using	enable_if_string = typename std::enable_if< is_string< T >::value >::type
	Enables an overload only for the string types nanodbc binds as strings.
template<typename T >
using	enable_if_character = typename std::enable_if< is_character< T >::value >::type
	Enables an overload only for the character types nanodbc binds as strings.

Functions
result_iterator	begin (result &r)
	Returns an iterator to the beginning of the given result set.
result_iterator	end (result &) noexcept
	Returns an iterator to the end of a result set.
std::list< driver >	list_drivers ()
	Returns a list of ODBC drivers on your system.
std::list< datasource >	list_datasources ()
	Returns a list of ODBC data sources on your system.
result	execute (connection &conn, string const &query, long batch_operations=1, long timeout=0)
	Immediately opens, prepares, and executes the given query directly on the given connection.
void	just_execute (connection &conn, string const &query, long batch_operations=1, long timeout=0)
	Opens, prepares, and executes query directly without creating result object.
result	execute (statement &stmt, long batch_operations=1)
	Execute the previously prepared query now.
void	just_execute (statement &stmt, long batch_operations=1)
	Execute the previously prepared query now and without creating result object.
result	transact (statement &stmt, long batch_operations)
	Execute the previously prepared query now.
void	just_transact (statement &stmt, long batch_operations)
	Execute the previously prepared query now and without creating result object.
void	prepare (statement &stmt, string const &query, long timeout=0)
	Prepares the given statement to execute on it associated connection.

Detailed Description

The entirety of nanodbc can be found within this one namespace.

Note

This library does not make any exception safety guarantees, but should work just fine with a threading enabled ODBC driver. If you want to use nanodbc objects in threads I recommend each thread keep their own connection to the database. Otherwise you must synchronize any access to nanodbc objects.

Typedef Documentation

string

typedef unspecified type nanodbc::string

string will be std::u16string or std::32string if NANODBC_ENABLE_UNICODE defined.

Otherwise it will be std::string.
