MySQL의 날짜 범위에서 어떻게 일을 생성합니까?


adddate() 함수를 사용하는 다음 쿼리의 도움으로 수행할 수 있으며 '2016-12-15'와 '2016-12-31' 사이의 날짜를 생성합니다.

mysql> select * from
    -> (select adddate('1970-01-01',t4*10000 + t3*1000 + t2*100 + t1*10 + t0) gen_date from
    -> (select 0 t0 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
    -> (select 0 t1 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
    -> (select 0 t2 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
    -> (select 0 t3 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
    -> (select 0 t4 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) v
    -> Where gen_date between '2016-12-15' and '2016-12-31'
    -> ;
