irport報表，把數字金額轉換成大寫人民幣金額

1、編寫oracle函式

create or replace function moneytochinese(money in number) return varchar2 is

stryuan varchar2(150);
stryuanfen varchar2(152);
numlenyuan number;
numlenyuanfen number;
strrstyuan varchar2(600);
strrstfen varchar2(200);
strrst varchar2(800);
numunitindex number;
i number;
j number;
charcurrentnum char(1);
begin
if money is null then
return null;
end if;
stryuan := to_char(floor(money));
if stryuan = '0' then
numlenyuan := 0;
stryuanfen := lpad(to_char(floor(money * 100)), 2, '0');
else
numlenyuan := length(stryuan);
stryuanfen := to_char(floor(money * 100));
end if;
if stryuanfen = '0' then
numlenyuanfen := 0;
else
numlenyuanfen := length(stryuanfen);
end if;
if numlenyuan = 0 or numlenyuanfen = 0 then
strrst := '零元整';
return strrst;
end if;
for i in 1 .. numlenyuan loop
j := numlenyuan - i + 1;
numunitindex := mod(i, 8);
if numunitindex = 0 then
numunitindex := 8;
end if;
if numunitindex = 1 and i > 1 then
end if;
charcurrentnum := substr(stryuan, j, 1);
if charcurrentnum <> 0 then
else
if (i = 1 or i = 5) then
if substr(stryuan, j - 3, 4) <> '0000' then
end if;
else
if substr(stryuan, j + 1, 1) <> '0' then
end if;
end if;
end if;
end loop;
for i in -2 .. -1 loop
j := numlenyuan - i;
charcurrentnum := substr(stryuanfen, j, 1);
if charcurrentnum <> '0' then
strrstfen;
end if;
end loop;
if strrstyuan is not null then
strrstyuan := strrstyuan || '元';
end if;
if strrstfen is null then
strrstyuan := strrstyuan || '整';
elsif length(strrstfen) = 2 and substr(strrstfen, 2) = '角' then
strrstfen := strrstfen || '整';
end if;
strrst := strrstyuan || strrstfen;
--strrst := replace(strrst, '億零', '億');
--strrst := replace(strrst, '萬零', '萬');
return strrst;
end moneytochinese;

小結：(select moneytochinese((select sum(sod.actual_unit_price * sod.actual_quantity) from sale_order_detail sod where sod.sale_order_no = oci.sell_order_no)) from dual) as majuscule_price

其中moneytochinese是函式名。sum(sod.actual_unit_price * sod.actual_quantity) 是總金額，加工數量*單價的和。
