Question

INSERT INTO print_development.categories (id, name) 
VALUES (select id, name from print_pro.categories where parent_id is NULL); 

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'select id, name from print_pro.categories where parent_id is NULL)' at line 2 

Answer 1

你有錯誤的INSERT/SELECT語法。你不使用「VALUES」，只需使用SELECT。

INSERT INTO print_development.categories (id, name) 
select id, name from print_pro.categories where parent_id is NULL
