UNIV_INLINE void sel_assign_into_var_values	(	sym_node_t *	var,
		sel_node_t *	node
	)

Assigns the values in the select list to the possible into-variables in SELECT ... INTO ...

Parameters

var	in: first variable in a list of variables
node	in: select node

Definition at line 338 of file row0sel.cc.

Here is the call graph for this function:

UNIV_INTERN void sel_col_prefetch_buf_free ( sel_buf_t * prefetch_buf )

Frees a prefetch buffer for a column, including the dynamically allocated memory for data stored there.

Parameters

prefetch_buf in, own: prefetch buffer

Definition at line 524 of file row0sel.cc.
