PT_derived_table()

PT_derived_table::PT_derived_table	(	const POS &	pos,

		const LEX_CSTRING &	table_alias,
		Create_col_name_list *	column_names

Member Function Documentation

add_json_info()

void PT_derived_table::add_json_info ( Json_object *  json_obj )

overrideprotectedvirtual

Add all the node-specific json fields.

Any class that needs to add such info should override this function rather than doing it in do_contextualize(). E.g. the parse tree node for AVG() may have "distinct" field to indicate if AVG(DISTINCT ...) is used or not.

Parameters

json_obj

Json object for this parse tree node.

Reimplemented from Parse_tree_node_tmpl< Context >.

do_contextualize()

bool PT_derived_table::do_contextualize ( Parse_context *  pc )

override
