Question

I have two tables

TABLE : EMPLOYEE

EMP_ID  EMP_NAME    EMP_TYPE
1   Shwetha           1
2   Raj               1
3   Mani              1
4   Sita              2
5   Rani              3
6   Guna              2

TABLE : EMPMAP

MAP_ID (PK) EMP_ID  EMPMAP_ID
1             1 4
2             4 5
3             1 6

In 2nd table it shows emp 4 is under 1, and 4 is under 5 and again 6 is under 1

I want to fetch employees who are working under a particular employee. For example, I want details of employees 4 and 5 if I pass empid 1 to the query and details of 5 if I want for 4.

Can anyone tell me how can I write the query for this?

Answer 1

select e.*
from EMPMAP map
join EMPLOYEE e on e.EMP_ID = map.EMPMAP_ID
where map.EMP_ID = @empId
