Member Function Documentation

virtual void fatalmind::Command< fatalmind::oracle::ResourceType< TM, SLMDC > >::execute

(

typename fatalmind::oracle::ResourceType< TM, SLMDC > ::resource_t &

rr

)

[pure virtual, inherited]

The execute method is the one which actually carries out the work.

This method gets called by ResourcePool with a (valid) plain resource which was obtained from the pool.

On normal execution (no exception) the resource will be free()ed, on abnormal execution (exception) the resource will be failed. If you need to throw an functional exception which should not cause failing of the resource, derive this exception from NoFailoverException.

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

template<typename T>

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

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. Chaning 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!

Reimplemented from fatalmind::SQL::BindInterface.

template<class TM, template< class > class SLMDC>

std::string fatalmind::oracle::CommandCommon< TM, SLMDC >::_SQL [protected]

this is a copy of the original SQL statement.

since oracle doesn't support '?' placeholders we will do the parsing our selves. so this is actually not the SQL sent to oracle
