Varun Gupta	befc09f002	MDEV-16722: Assertion `type() != NULL_ITEM' failed ... We hit this assert during the create of a temporary table field because the current code does not handle the case when the value of the NAME_CONST function is NULL. Fixed this by allowing creation of temporary table fields even for the case when NAME_CONST returns NULL value. Introduced tmp_table_field_from_field_type_maybe_null() function in Item class so both Item_basic_value and Item_name_const can use it. Introduced a virtual method get_func_item() in the Item class.	2018-08-12 12:09:56 +05:30
