template<class VBC, template< class > class CT>

virtual void fatalmind::SQL::Bind< VBC, CT >::bind	(	const unsigned int	pos,
		const char &	val,
		bool	isnull = false
	)			[inline, virtual]

Binds an actual input value for an placeholder in the SQL statement.

All binding is done by value! This means the passed data are copied to internal storage. Changing your original copy of your data after passing it to bind() is therefore safe.

Parameters:

	pos	The position indicator. The number of placeholder (?) in the SQL string. Counted from the left starting at 0.
	val	the actual value.
	nul	NULL inidcator, if set to yes the actual value to be bound will be NULL. Please note that you still need to provide a valid value!

Implements fatalmind::SQL::BindInterface.
