How to find out hierchy of employee?

["VivekanandaSwamy R." <VivekanandaSwamyr(at)infics(dot)com>]

Hai,

I have proper knowledge in Oracle 9i as wel as PostgreSQL.

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?

 

 

 

Thanks  &  Regards
