Every derived table must have its own alias - error when using multiple SELECT statements

Question

I\'m trying to use multiple SELECT statements in a query to get data from the database but I get an error. The query is:

SELECT * 
        FROM (SELECT * 
               


        

Answer 1

The from table needs an alias

SELECT * 
        FROM (SELECT * 
              FROM players 
              WHERE lid = 0) as T
        WHERE NOT EXISTS (SELECT * 
                          FROM players 
                          WHERE lid = 1)

Will work

Though the query seems to make no sense. It is not a syntax error anymore
