Re: How to find out hierchy of employee?

["Derrick Betts" <derrick(at)blueaxis(dot)com>]

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.

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
