如何實現(xiàn)存儲過程返回數(shù)組對象

本篇內(nèi)容主要講解“如何實現(xiàn)存儲過程返回數(shù)組對象”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學(xué)習(xí)“如何實現(xiàn)存儲過程返回數(shù)組對象”吧!

其實就相當于返回List里面放的對象數(shù)據(jù)，定義如下

1.創(chuàng)建存儲過程對象

復(fù)制代碼 代碼如下:

CREATE OR REPLACE TYPE "T_ACCOUNT_MONTH"
as object(
ACCOUNT_ID NUMBER,
INIT_AMOUNT NUMBER,
DEBIT_AMOUNT NUMBER,
CREDIT_AMOUNT NUMBER
)

2.創(chuàng)建存數(shù)過程數(shù)組

復(fù)制代碼 代碼如下:

CREATE OR REPLACE TYPE "T_ACCOUNT_MONTH_TABLE"
as table of t_account_month

3.創(chuàng)建存儲過程

復(fù)制代碼 代碼如下:

create or replace function account_month(tDate IN DATE)
return t_account_month_table pipelined
as
v_account_month t_account_month;
v_date DATE;
begin
v_date:=tDate;
IF v_date IS NULL THEN
v_date:=sysdate;
END IF;
for myrow in (
select d.ACCOUNT_ID,
sum(decode(sign(d.create_time-trunc(v_date,'month')),-1,
d.debit_unvoucher + d.debit_unposted +d.debit_posted - d.CREDIT_UNVOUCHER -d.CREDIT_UNPOSTED- d.CREDIT_POSTED_D,
0)) INIT_AMOUNT,
sum(decode(sign(trunc(d.create_time,'year')-trunc(sysdate,'year')),0,
d.debit_unposted+d.debit_posted,
0)) DEBIT_AMOUNT,
sum(decode(sign(trunc(d.create_time,'year')-trunc(sysdate,'year')),0,
d.credit_unposted+d.credit_posted,
0)) CREDIT_AMOUNT
from ACCOUNT_DAILY_VEIW d
group by d.ACCOUNT_ID
) loop
v_account_month := t_account_month(
myrow.ACCOUNT_ID,
myrow.INIT_AMOUNT,
myrow.DEBIT_AMOUNT,
myrow.CREDIT_AMOUNT
);
pipe row (v_account_month);
end loop;
return;
end;

到此，相信大家對“如何實現(xiàn)存儲過程返回數(shù)組對象”有了更深的了解，不妨來實際操作一番吧！這里是億速云網(wǎng)站，更多相關(guān)內(nèi)容可以進入相關(guān)頻道進行查詢，關(guān)注我們，繼續(xù)學(xué)習(xí)！
