低版本中mysql不支持在limit语句中有子查询

Posted 2022-11-26 汤高

select * from  exec_activity_effect_day oe where oe.ACTIVITY_ID  in   (select  DISTINCT(e.ACTIVITY_ID) from exec_activity_effect_day e limit 0 ,3) 

[SQL] select * from  exec_activity_effect_day oe where oe.ACTIVITY_ID  in   (select  DISTINCT(e.ACTIVITY_ID) from exec_activity_effect_day e limit 0 ,3) 


[Err] 1235 - This version of mysql doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

低版本中mysql不支持在limit语句中有子查询

所以只要在有limit的语句里再向外包一层

( select t.ACTIVITY_ID from (select  DISTINCT(e.ACTIVITY_ID) from exec_activity_effect_day e limit 0 ,3) as t)

把上面的结果作为一个新的t表

再查t表就ok ,整个语句如下

SELECT
*
FROM
exec_activity_effect_day oe
WHERE
oe.ACTIVITY_ID IN (
SELECT
t.ACTIVITY_ID
FROM
(
SELECT DISTINCT
(e.ACTIVITY_ID)
FROM
exec_activity_effect_day e
LIMIT 0,
3
)AS t
)
