Constructor & Destructor Documentation

◆ PT_derived_table()

PT_derived_table::PT_derived_table ( const POS pos,
bool  lateral,
PT_subquery subquery,
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_objJson 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

Member Data Documentation

◆ column_names

const Create_col_name_list PT_derived_table::column_names
private
