Re: How to find out hierchy of employee?

In looking at your result set, it appears that there is no way of determining which employee is responsible to which manager. This is how I've done it:
Every employee is assigned a StationID. For example a Sr. Manager or Administrator is assigned an ID of 'B01' (Business unit 01).
Then every manager under that Sr. Manager is assigned a StationID that ties them to the Sr. Manager. For Example 'B01A', or 'B01B' ... 'B01ZZ'.
Then every employee under that Manager is assigned a StationID that ties them to their specific Manager. For example 'B01A1' or 'B01A2'. Or for a different Manager 'B01ZZ1' or 'B01ZZ2'.

Now you can do a query to select all employees under a Sr. Manager, Manager, or etc. by performing this type of simple Query:
"SELECT employee_name WHERE stationid LIKE 'B01%';" This will return all the employees whose StationID matches that of the Sr. Manager. If you only want the employees under a Manager, just change the LIKE clause in the query to: LIKE 'B01ZZ%'

Hope this helps.

Hai,

I have written a query in Oracle-SQL like the following...

select level,substr(lpad(' ',level*2)||ename,1,20) name from emp
start with ename='KING'
connect by prior empno=MGR;
/
LEVEL NAME
---------- -----------
1 KING
2 JONES
3 SCOTT
4 ADAMS
3 FORD
4 SMITH
2 BLAKE
3 ALLEN
3 WARD
3 MARTIN

Now, i need same result in PostgreSQL.Is there any possiblity to find out the heirchy of employees?
