我有个问题不知道怎么解决。
我得到了这个选择
select
p.id as pId, -- 0
p.code,
p.name
from work_order as wo
left join project as p on wo.project_fk = p.id
where date(wo.date1) >= :initialDate
and date(wo.date1) <= :initialDate
group by p.id
order by p.code asc
我得到了一个参数(:state)，有3个可能的值'1'、'2'或'3'，以及一个有多个值的表域(state_fk)。我希望根据参数的值来选择state_fk的值。接下来的代码是错误的，但它可以给你和想法，我需要什么。
select
p.id as pId, -- 0
p.code,
p.name
from work_order as wo
left join project as p on wo.project_fk = p.id
where date(wo.date1) >= :initialDate
and date(wo.date1) <= :initialDate
and ( (case :state = '1' then ('abc', 'qwe') end) in state_fk
or (case :state = '2' then ('cdw', 'zxc', 'ere') end) in state_fk
or (case :state = '3' then ('swq', 'bge', 'qah') end) in state_fk )
group by p.id
order by p.code asc
如果有人能告诉我如何正确地做，我会非常感激。
如果没有表的定义，我们就很难做到这一点，这样我们就可以测试了。但是像这样的东西应该可以用。
select
p.id as pId, -- 0
p.code,
p.name
from work_order as wo
left join project as p on wo.project_fk = p.id
where date(wo.date1) >= :initialDate
and date(wo.date1) <= :initialDate
and (
(:state = '1' and state_fk in ('abc', 'qwe'))
OR
(:state = '2' and state_fk in ('cdw', 'zxc', 'ere'))
OR
(:state = '3' and state_fk in ('swq', 'bge', 'qah'))
)
group by p.id
order by p.code asc
