Description
In current code, we have in table.cc:
/*
|
Procedure of keys generation for result tables of materialized derived
|
tables/views.
|
|
|
A key is generated for each equi-join pair derived table-another table.
|
...
|
*/ |
/*
|
@brief
|
Change references to underlying items of a merged derived table/view
|
for fields in derived table's result table.
|
|
|
@return FALSE ok
|
@return TRUE Out of memory
|
*/

bool TABLE_LIST::change_refs_to_fields() |
The first comment is out of place.
It should have been at sql_select.cc, generate_derived_keys().
The comment was added in this commit:
