的MySQL還不支持 '限制和IN/ALL/ANY/SOME子查詢'

Question

當我運行此查詢

SELECT * FROM 
tb_emp_daily_status d 
where 
d.shiftdate>='2017-06-07' and 
shiftdate<='2017-06-13' and 
emp_id in (SELECT id FROM tb_employee e WHERE e.user_id = '18145' LIMIT 20) 
order by d.id asc 

如何寫mysql的這個查詢

Answer 1

試試這個：

SELECT * FROM 
    tb_emp_daily_status d 
    where 
    d.shiftdate>='2017-06-07' and 
    shiftdate<='2017-06-13' and 
    emp_id in (SELECT * FROM (SELECT id FROM tb_employee e WHERE e.user_id = '18145' LIMIT 20) 
      as t) 
    order by d.id asc 

Answer 2

而不是IN子查詢，你可以使用曾經與子查詢結果

SELECT * FROM 
    tb_emp_daily_status d 
    INNER JOIN ( 
    SELECT id FROM tb_employee e WHERE e.user_id = '18145' LIMIT 20 
) t on d.emp_id = t.id 
    where d.shiftdate>='2017-06-07' and 
    shiftdate<='2017-06-13' and 
    order by d.id asc
