Constructors
Connector
Connector();
Creates the Connector.
Destructor
~Connector 
~Connector();
Destroys the Connector.
Member Functions
bindStringToLongVarChar 
static void bindStringToLongVarChar(
bool flag = true
);
If set to true (default), std::string is bound to SQL_LONGVARCHAR.
This can cause issues with SQL Server, resulting in an error ("The data types varchar and text are incompatible in the equal to operator") when comparing against a VARCHAR.
Set this to false to bind std::string to SQL_VARCHAR.
NOTE: This is a global setting, affecting all sessions. This setting should not be changed after the first Session has been created.
createSession
Poco::AutoPtr < Poco::Data::SessionImpl > createSession(
const std::string & connectionString,
std::size_t timeout = Poco::Data::SessionImpl::LOGIN_TIMEOUT_DEFAULT
);
Creates a ODBC SessionImpl object and initializes it with the given connectionString.
name 
const std::string & name() const;
Returns the name associated with this connector.
See also: Poco::Data::Connector::name()
registerConnector
static void registerConnector();
Registers the Connector under the Keyword Connector::KEY at the Poco::Data::SessionFactory
stringBoundToLongVarChar
static bool stringBoundToLongVarChar();
Returns true if std::string is bound to SQL_LONGVARCHAR, otherwise false (bound to SQL_VARCHAR).
unregisterConnector
static void unregisterConnector();
Unregisters the Connector under the Keyword Connector::KEY at the Poco::Data::SessionFactory
Variables
KEY
static const std::string KEY;
Keyword for creating ODBC sessions.
