MDEV-22391 Assertion `0' failed in Item_type_holder::val_str on utf16…
… charset table query Problem: When handling a query like this: VALUES ('') UNION SELECT _utf16 0x0020 COLLATE utf16_bin; Type_handler_string_result::Item_hybrid_func_fix_attributes() tried to apply character set conversion Item_type_holder, which causes a crash on DBUG_ASSERT(0) inside Item_type_holder::val_str(). Fix: Overriding Item_type_holder's methods to avoid this, as follows: bool const_item() const { return false; } bool is_expensive() { return true; }
