【问题描述】*：where条件后有case when语句怎么处理，如下SQL报错
select ifnull(count(1),0) from yx_sealInfo_confirm t1
LEFT JOIN yx_sealinfo_apply t5
ON t1.seal_apply_id = t5.id
LEFT JOIN yx_seal t2 ON t1.seal_id = t2.id
where t5.deleted = 0 and
t1.status in ('FLOW_SEAL_DESTORY','FLOW_SEAL_DEACTIVATE','FLOW_SEAL_RECOVERY','FLOW_SEAL_CHANGE','FLOW_SEAL_CHANGECHAPTER')
and t2.deleted =0 and t1.confirm_status=0
and t1.unit_id = '2c90ba84894abab1018a2c569ae34adf' and t2.unit_id = '2c90ba84894abab1018a2c569ae34adf'
and t5.unit_id = '2c90ba84894abab1018a2c569ae34adf'
and case when t1.status<>'FLOW_SEAL_DESTORY' then t2.seal_status<>2 and t1.deleted = 0 else t1.deleted = 0 end
and ( t2.department_id != '-1' or t2.create_id = '8a80837a8bea51f8018bea5239f60003')

试一下下面这个改写的SQL是否能正常执行。
另，如果 status 字段没有NULL值，可不做NVL处理

select ifnull(count(1),0) 
  from yx_sealInfo_confirm t1
  LEFT JOIN yx_sealinfo_apply t5 ON t1.seal_apply_id = t5.id
  LEFT JOIN yx_seal           t2 ON t1.seal_id = t2.id
 where t5.deleted = 0 
   and t1.status in ('FLOW_SEAL_DESTORY','FLOW_SEAL_DEACTIVATE','FLOW_SEAL_RECOVERY'
                    ,'FLOW_SEAL_CHANGE','FLOW_SEAL_CHANGECHAPTER')
   and t2.deleted =0 
   and t1.confirm_status=0
   and t1.unit_id = '2c90ba84894abab1018a2c569ae34adf' 
   and t2.unit_id = '2c90ba84894abab1018a2c569ae34adf'
   and t5.unit_id = '2c90ba84894abab1018a2c569ae34adf'
   --and case when t1.status<>'FLOW_SEAL_DESTORY' then t2.seal_status<>2 and t1.deleted = 0 else t1.deleted = 0 end
   and (   (t1.status<>'FLOW_SEAL_DESTORY' and t2.seal_status<>2 and t1.deleted = 0) 
        or (nvl(t1.status,'FLOW_SEAL_DESTORY') = 'FLOW_SEAL_DESTORY' and t1.deleted = 0)
       )
       
   and ( t2.department_id != '-1' or t2.create_id = '8a80837a8bea51f8018bea5239f60003')
