1、先要声明全局type;并且,字段变量类型要为object,不能为record:
(1)CREATE OR REPLACE TYPE "DDD_BY_DEPT_STATISTISC" is object ( --建立一个对象
DEPT_CODE VARCHAR2(200),
DEPT_NAME VARCHAR2(200),
SYQD NUMBER,
ZKZTS NUMBER
)
(2)CREATE OR REPLACE TYPE "DDD_BY_DEPT_STATISTISC_TB" is table of DDD_BY_DEPT_STATISTISC--包含对象的table
2、建立一个带返回值的函数
create or replace function fn_get_antib_statistisc(BILLING_DATE_MIN IN varchar2, BILLING_DATE_MAX IN varchar2,TIME_TYPE IN VARCHAR2)--TIME_TYPE 发生=1结算=2
return TP_ANTIBIOTIC_STATISTISC_TB
is
o_tb TP_ANTIBIOTIC_STATISTISC_TB := TP_ANTIBIOTIC_STATISTISC_TB();
i number := 0;
TIME_TYPES VARCHAR2(20):=TIME_TYPE;
cursor cur is--建立游标,先把要返回的内容放在游标里
select patient_id,
pat_name,
doctor,
drdered_by,
dept_name,
visit_id,
sum(costs) costs,
rcpt_no,
statistisc_bz from antibiotic_statistisc
OPERATION_STATISTICS where date_time>=to_date(BILLING_DATE_MIN,'yyyy-mm-dd')
and date_time<to_date(BILLING_DATE_MAX,'yyyy-mm-dd')+1 and STATISTISC_BZ=TIME_TYPES group by patient_id,
pat_name,
doctor,
drdered_by,
dept_name,
visit_id,
rcpt_no,
statistisc_bz;
begin
for Temp in cur loop--循环将游标里的对象赋值到装对象的集合中
o_tb.extend;-------A
i := i + 1;----------B 每次向o_tb添加对象时都要进行AB操作
o_tb(i) := TP_ANTIBIOTIC_STATISTISC (
Temp.patient_id,
Temp.pat_name,
Temp.doctor,
Temp.drdered_by,
Temp.dept_name,
Temp.visit_id,
Temp.costs,
Temp.rcpt_no,
'',
Temp.statistisc_bz
);
end loop;
return o_tb;
end fn_get_antib_statistisc;
