Hmmm ....
create or replace function myfunc (in_userlist in varchar2)
return varchar2 is
-- in_userlist is a comma delimited list of user numbers
szRtnVar varchar2(1000) := null;
--
szSqlText varchar2(1000) := null;
vRefCur REF CURSOR;
begin
szSqltext := 'select nvl(weight, 0) from tablea where usera in (' ||
in_userlist || ')';
open vRefCur for szSqltext;
loop
fetch vRefCur into szTmp;
exit when vRefCur%notfound;
szRtnVar := szRtnVar || ',' || to_char(szTmp);
end loop;
if vRefCur%isopen then
close vRefCur;
end if;
return (ltrim(szRtnVar,','));
end myfunc;
/
or if you have 8i, 9i then try this ...
create or replace function myfunc (in_userlist in varchar2)
return varchar2 is
-- in_userlist is a comma delimited list of user numbers
szRtnVar varchar2(1000) := null;
--
itTmpTab dbms_utility.uncl_array; -- table type definition for
varchar2
szSqlText varchar2(1000) := null;
vRefCur REF_CURSOR;
nRows number := 0; -- holds number of rows
begin
szSqltext := 'select to_char(nvl(weight, 0)) from tablea where usera in ('
|| in_userlist || ')';
execute immediate szSqlText BULK COLLECT into itTmpTab;
dbms_utility.table_to_comma(itTmpTab, nRows, szRtnVar);
return (szRtnVar);
end myfunc;
/
Of course check for syntaxes etc. Both these examples assume that the "in"
parameter is of type a,b,c,d etc.
