Re: function call error

For the second function you called select getmatch without specifying the columns you want.
try select * from getmatch()

Hi
I have the following functions , the functions are created but when it is invoked it errors out /

SampleDB=# create or replace function getmatch(anyarray) returns anyarray as $$
SampleDB$# declare
SampleDB$# sys_cursor cursor(key integer) is select sys_id from subsystems wher
sys_id = key;
SampleDB$# result integer[];
SampleDB$# loop_id integer;
SampleDB$# begin
SampleDB$# open sys_cursor($1[1]);
SampleDB$# loop
SampleDB$# fetch sys_cursor into loop_id;
SampleDB$# array_append(result,loop_id);
SampleDB$# end loop;
SampleDB$# close sys_cursor;
SampleDB$# return result[];
SampleDB$# end;
SampleDB$# $$ language plpgsql;
CREATE FUNCTION
SampleDB=# select getmatch(array[2]);
ERROR: syntax error at or near "array_append" at character 1
QUERY: array_append( $1 , $2 )
CONTEXT: PL/pgSQL functio n "getmatch" line 9 at SQL statement
LINE 1: array_append( $1 , $2 )

and the second function is similar

SampleDB=# create or replace function getmatch() returns setof integer as $$
SampleDB$# declare
SampleDB$# sys_cursor cursor is select sys_id from subsystems;
SampleDB$# loop_id subsystems.sys_id%type;
SampleDB$# begin
SampleDB$# open sys_cursor;
SampleDB$# loop
SampleDB$# fetch sys_cursor into loop_id;
SampleDB$# return next loop_id;
SampleDB$# end loop;
SampleDB$# close sys_cursor;
SampleDB$# return;
SampleDB$# end;
SampleDB$# $$ language plpgsql;
CREATE FUNCTION
SampleDB=# select getmatch();
ERROR: set-valued function called in context that cannot accept a set
CONTEXT: PL/pgSQL function "getmatch" line 8 at return next

what is wrong in my function ,
anyhelp asap?
Thanks
Vidya
