Query graph

Created 5/27/1996 Heikki Tuuri

Function Documentation

UNIV_INLINE que_node_t* que_fork_get_child ( que_fork_t * fork )

Gets the child node of the first thr in a fork.

Parameters

fork	in: query fork

UNIV_INLINE que_thr_t* que_fork_get_first_thr ( que_fork_t * fork )

Gets the first thr in a fork.

Parameters

fork	in: query fork

UNIV_INLINE ibool que_graph_is_select ( que_t * graph )

Returns TRUE if the query graph is for a SELECT statement.

Returns: TRUE if a select

Parameters

graph in: graph

UNIV_INLINE dtype_t* que_node_get_data_type ( que_node_t * node )

Gets pointer to the value data type field of a graph node.

Parameters

node	in: graph node

UNIV_INLINE que_node_t* que_node_get_next ( que_node_t * node )

Gets the next list node in a list of query graph nodes.

Returns: next node in a list of nodes

Parameters

node	in: node in a list

UNIV_INLINE que_node_t* que_node_get_parent ( que_node_t * node )

Gets the parent node of a query graph node.

Returns: parent node or NULL

Parameters

node in: node

UNIV_INLINE ulint que_node_get_type ( que_node_t * node )

Gets the type of a graph node.

Parameters

node	in: graph node

UNIV_INLINE dfield_t* que_node_get_val ( que_node_t * node )

Gets pointer to the value dfield of a graph node.

Parameters

node	in: graph node

UNIV_INLINE ulint que_node_get_val_buf_size ( que_node_t * node )

Gets the value buffer size of a graph node.

Returns: val buffer size, not defined if val.data == NULL in node

Parameters

node	in: graph node

UNIV_INLINE que_node_t* que_node_list_add_last	(	que_node_t *	node_list,
		que_node_t *	node
	)

Catenates a query graph node to a list of them, possible empty list.

Returns: one-way list of nodes

Parameters

node_list	in: node list, or NULL
node	in: node

UNIV_INLINE ulint que_node_list_get_len ( que_node_t * node_list )

Gets a query graph node list length.

Returns: length, for NULL list 0

Parameters

node_list in: node list, or NULL

UNIV_INLINE void que_node_set_parent	(	que_node_t *	node,
		que_node_t *	parent
	)

Sets the parent of a graph node.

Parameters

node	in: graph node
parent	in: parent

UNIV_INLINE void que_node_set_val_buf_size	(	que_node_t *	node,
		ulint	size
	)

Sets the value buffer size of a graph node.

Parameters

node	in: graph node
size	in: size

UNIV_INLINE ibool que_thr_peek_stop ( que_thr_t * thr )

Checks if graph, trx, or session is in a state where the query thread should be stopped.

Returns: TRUE if should be stopped; NOTE that if the peek is made without reserving the trx mutex, then another peek with the mutex reserved is necessary before deciding the actual stopping

Parameters

thr	in: query thread

UNIV_INLINE trx_t* thr_get_trx ( que_thr_t * thr )

Gets the trx of a query thread.

Parameters

thr	in: query thread

UNIV_INLINE ibool thr_is_recv ( const que_thr_t * thr )

Determines if this thread is rolling back an incomplete transaction in crash recovery.

Returns: TRUE if thr is rolling back an incomplete transaction in crash recovery

Parameters

thr	in: query thread
