MDEV-35276 Assertion failure in find_producing_item upon a query from a view
|
|
Two problem solved:
|
|
1) Item_default_value makes a shallow copy so the copy
|
should not delete field belong to the Item
|
|
2) Item_default_value should not inherit
|
derived_field_transformer_for_having and
|
derived_field_transformer_for_where (in this variant
|
pushing DEFAULT(f) is prohibited (return NULL) but
|
if return "this" it will be allowed (should go with
|
a lot of tests))
|
Re-assigning to sanja so he can probably close this as a duplicate of MDEV-35276 .
Thanks!
