You should try it as follows:
create or replace function subfun1(int8) returns record as
'
declare
rec record;
begin
select ename as ename,mgr as mgr into rec from emp where empno=$1 ;
return rec;
end;
'
language'plpgsql';
'
declare
rec record;
begin
select ename as ename,mgr as mgr into rec from emp where empno=$1 ;
return rec;
end;
'
language'plpgsql';
---------------------------------------------------------
select subfun1(22);
subfun1
-------------
(swarna,23)
-------------
(swarna,23)
------------------------------------------------------------
create or replace function mainfun(int8) returns record as
'
declare
no record;
return_rec record;
begin
no := subfun1($1);
select sal,dept into return_rec from emp where mgr=no.mgr limit 1;
return return_rec;
end;
'
language'plpgsql';
'
declare
no record;
return_rec record;
begin
no := subfun1($1);
select sal,dept into return_rec from emp where mgr=no.mgr limit 1;
return return_rec;
end;
'
language'plpgsql';
-------------------------------------------------
select mainfun(22);
mainfun
-----------

Subject: [ADMIN] How to cal function in in another function
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';
'
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';
'
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
CONTEXT: PL/pgSQL function "mainfun" line 5 at select into variables
So,how to solve this problem?
Thanks & Regards
