How to cal function in in another function

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

Hi,

i have written these functions....,please go through this...

 

table emp: It contains

 

empno     ename           mgr            sal          dept

-------------------------------------------------------------------------

22            swarna           23             2600            20

 

Now i wrote function(sub function)

 

create or replace function subfun1(int8,out p_mgr int8,out p_name varchar) as
'
begin
select ename,mgr into p_name,p_mgr from emp where empno=$1 ;
end;
'
language'plpgsql';

 

 When i executing this function,it returns like....

select subfun1(22);         returns (23,swarna) as record type

 

Now i want use/call this function in main function

   

create or replace function mainfun(int8,out p_sal int8,out p_dept varchar) as
'
declare
no record;
begin
select subfun1($1) into no;
select sal,dept into p_sal,p_dept from emp where mgr=no.p_mgr limit 1;
end;
'
language'plpgsql';

 

Now when i am executing this function like....

 

select mainfun(22);   returns error message like....

 

    ERROR:  record "no" has no field "p_mgr"
    CONTEXT:  PL/pgSQL function "mainfun" line 5 at select into variables

 

So,how to solve this problem?

 

   

 

       

 

 

 

 

Thanks  &  Regards
