Question

I’m trying to use JOIN but it seems I am only getting half of the result. Below are the tables and required output.

I’m not getting any error.
When I used JOIN it only shows the approver1. So What I did is:

SELECT tb1.*, tb2.name AS a1, tb3.name AS a2 
FROM   table1 tb1 
       LEFT JOIN approver tb2 
       ON tb1.approve1 = tb2.id 
       LEFT JOIN approver tb3 
       ON tb1.approver2 = tb2.id

Any help or clue would be greatly appreciated.

Answer 1

Select empname, ap_1.name, ap_2.name from Employee 
left join Approver as ap_a on (Employee.approver1 = ap_1.id)
left join Approver as ap_b on (Employee.approver2 = ap_2.id)
