Error while converting function from oracle to mssql
- by sss
Hi,
I am migrating a function from oracle to mssql 2008.This function raises Select statements included within a function cannot return data to a client as error.How can i solve this problem?
Original PLSQL Code
CREATE OR REPLACE function f_birim_cevrim_katsayi (p_ID_MAMUL in number, p_ID_BIRIMDEN in number, p_ID_BIRIME in number)
return number
is
v_katsayi number;
begin
v_katsayi:=0;
if p_ID_BIRIMDEN!=p_ID_BIRIME then
for c in (
select * from CR_BIRIM_CEVRIM
where ID_MAMUL = p_ID_MAMUL
and (
(ID_BIRIM = p_ID_BIRIMDEN and ID_BIRIM2 = p_ID_BIRIME)
OR ( ID_BIRIM2 = p_ID_BIRIMDEN and ID_BIRIM = p_ID_BIRIME) )
and VALID = 1)
loop
if c.ID_BIRIM=p_ID_BIRIMDEN then
v_katsayi:=c.MT_ORAN;
else
v_katsayi:=1/c.MT_ORAN;
end if;
end loop;
else
v_katsayi:=1;
end if;
return round(v_katsayi,10);
exception
when others then
return 0;
end;
TSQL CODE
If Exists ( SELECT name
FROM sysobjects
WHERE name = 'f_birim_cevrim_katsayi'
AND type = 'FN')
