Normally, this field is non-null for anonymous derived tables only.

@details This field is set to non-null for

  • Anonymous derived tables, In this case it points to the SELECT_LEX_UNIT representing the derived table. E.g. for a query

@verbatim SELECT * FROM (SELECT a FROM t1) b @endverbatim

For the @c TABLE_LIST representing the derived table @c b, @c derived points to the SELECT_LEX_UNIT representing the result of the query within parenteses.

  • Views. This is set for views with @verbatim ALGORITHM = TEMPTABLE @endverbatim by mysql_make_view().

@note Inside views, a subquery in the @c FROM clause is not allowed. @note Do not use this field to separate views/base tables/anonymous derived tables. Use TABLE_LIST::is_anonymous_derived_table().
