oracle帶不同參數個數的函數測試

1. oracle函數測試腳本

--兩個參數的
create or replace function searchStuInfoWith2Param(bonus number ,address varchar2)
 return number
 is
  totalSalaryVal number;
  taddress varchar2(70);
  tbonus number;
begin
  taddress := ''||address||'%';
  tbonus :=bonus;
 select  sum(BASESALARY)  into totalSalaryVal  from JK_TESTPROC where BONUS > tbonus and  ADDRESS like taddress;

  return(totalSalaryVal);
end searchStuInfoWith2Param;

-- 一個參數的
create or replace function searchStuInfo(s_stuNo number)
 return number
 is
  baseSalaryVal number;
begin
 select  BASESALARY  into baseSalaryVal  from JK_TESTPROC where ID=s_stuNo;

  return(baseSalaryVal);
end searchStuInfo;

--無參數的

create or replace function searchStuTotalSalary
 return number
 is
  totalSalaryVal number;
begin
 select  sum(BASESALARY)  into totalSalaryVal  from JK_TESTPROC;

  return(totalSalaryVal);
end searchStuTotalSalary;

create or replace function TestDateFunction(date_ in  DATE,address varchar2)
return number 

 is
 bonus number;
 taddress varchar2(70);

begin
  taddress := ''||address||'%';
  select BONUS into BONUS from JK_TESTPROC where BIRTHDATE < date_ and  ADDRESS like taddress;
  return bonus;
end TestDateFunction;

2. 創建數據庫表腳本
