如何在oracle預存程序中返回遊標

1：首先你需要建立一個包，並定義你返回的遊標的類型、預存程序

create or replace package TEST_PKG is
 
  -- Public type declarations
  type cur_emp is REF CURSOR;
 
  procedure test_proc (v_empno in number, emps out cur_emp);
 
end TEST_PKG;

2：然後你再建立包體

create or replace package body TEST_PKG is

procedure test_proc (v_empno in number, emps out cur_emp)
as
begin
open emps for select * from emp where empno=7369;
end test_proc; 
end TEST_PKG ;

3，通過JAVA調用

cstmt = conn.prepareCall("{call TEST_PKG .test_proc (?)}");
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
cstmt.execute();
  
//獲得結果集
rs = (ResultSet)cstmt.getObject(4);
while(rs.next()){......}
