Mysql 如何写一个查询包含where后跟条件

Question

我正在编写一个查询，它需要满足以下条件。

select 
    field1, field2, field3
from 
    `tabFirstTable`as ft join 
    `tabSecondTable` as st
where 
    --Upto above its fine but how to turn below logic into query-- 
    IF ft.approval_status in == 'Approved By Manager' and ft.status in ("Created", "Error")
        and //some more conditions
    ELSE ft.approval_status in == 'Approved By HOD' and ft.status in ("Initiated")
        and //some more conditions

由于上述问题，目前正在编写两个单独的查询，这不是一个好主意。 请帮忙。

Answer 1

除非我遗漏了什么或过度简化

WHERE
    (ft.status IN ('Created', 'Error') AND 
    ft.approval_status = 'Approved By Manager' AND 
        //other stuff
    )
OR 
    (ft.status = 'Initiated' AND 
     ft.approval_status = 'Approved By HOD' AND 
        //some more conditions
    )
