如何在oracle存储过程中返回游标

1：首先你需要创建一个包，并定义你返回的游标的类型、存储过程

 

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：然后你再创建包体

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，通过调用

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