Member Function Documentation

◆ finalize_query_expression()

bool Parse_context::finalize_query_expression ( )

Call upon parse completion.

Set the parsed query expression's query term.

Returns: true on error, else false

For its construction, see parse_tree_nodes.cc's contextualize methods. Query_term is documented in query_term.h .

◆ is_top_level_union_all()

bool Parse_context::is_top_level_union_all ( Surrounding_context op )

Determine if there is anything but UNION ALL above in m_stack.

Member Data Documentation

◆ m_stack

mem_root_deque<QueryLevel> Parse_context::m_stack

Aids query term tree construction.

◆ mem_root

MEM_ROOT* Parse_context::mem_root

Current MEM_ROOT.

◆ select

Query_block* Parse_context::select

Current Query_block object.

◆ thd

THD* const Parse_context::thd

Current thread handler.
