Detailed Description
Symbol table node
Field Documentation
| sym_node_t* sym_node_t::alias |
pointer to another symbol table node for which this node is an alias, NULL otherwise
| ulint sym_node_t::col_no |
column number if a column
| ut_list_node< sym_node_t > sym_node_t::col_var_list |
list of table columns or a list of input variables for an explicit cursor
| que_common_t sym_node_t::common |
node type: QUE_NODE_SYMBOL
| ibool sym_node_t::copy_val |
TRUE if a column and its value should be copied to dynamic memory when fetched
| sel_node_t* sym_node_t::cursor_def |
cursor definition select node if a named cursor
| ulint sym_node_t::field_nos[2] |
if a column, in the position SYM_CLUST_FIELD_NO is the field number in the clustered index; in the position SYM_SEC_FIELD_NO the field number in the non-clustered index to use first; if not found from the index, then ULINT_UNDEFINED
| sym_node_t* sym_node_t::indirection |
pointer to another symbol table node which contains the value for this node, NULL otherwise
| const char* sym_node_t::name |
name of an id
| ulint sym_node_t::name_len |
id name length
| ulint sym_node_t::param_type |
PARS_INPUT, PARS_OUTPUT, or PARS_NOT_PARAM if not a procedure parameter
| sel_buf_t* sym_node_t::prefetch_buf |
NULL, or a buffer for cached column values for prefetched rows
| ibool sym_node_t::resolved |
TRUE if the meaning of a variable or a column has been resolved; for literals this is always TRUE
| ut_list_node< sym_node_t > sym_node_t::sym_list |
list of symbol nodes
| sym_tab_t* sym_node_t::sym_table |
back pointer to the symbol table
| dict_table_t* sym_node_t::table |
table definition if a table id or a column id
| enum sym_tab_entry sym_node_t::token_type |
type of the parsed token
