Each derived table should have alias

Reports derived tables without aliases.

Example (MySQL):

CREATE TABLE table1 (id INT, name VARCHAR(20), cats FLOAT); CREATE TABLE table2 (id INT, age INTEGER); SELECT id AS ID, name, cats, age FROM (SELECT table1.id, name, cats, age FROM table1 JOIN table2 ON table1.id = table2.id);

According to Derived Tables at dev.mysql.com, an alias is mandatory. You can add the alias by using the Introduce alias quick-fix.

After the quick-fix is applied:

SELECT id AS ID, name, cats, age FROM (SELECT table1.id, name, cats, age FROM table1 JOIN table2 ON table1.id = table2.id);
