C#调用Oracle存储过程并返回结果集

1.创建一个存储过程:

create or replace procedure GET_PERSON
(
RC1 out sys_refcursor,
RC2 out sys_refcursor
)
is
begin
open RC1 for select * from PERSON;
open RC2 for select * from PERSON;
end GET_PERSON;

2.C#代码
OracleConnection conn = new OracleConnection("Data Source=XXX;User Id=scott;Password=tiger");
OracleCommand cmd = new OracleCommand("GET_PERSON", conn);
cmd.CommandType = CommandType.StoredProcedure;

OracleParameter param = new OracleParameter("RC1", OracleType.Cursor);
param.Direction = ParameterDirection.Output;
cmd.Parameters.Add(param);
param = new OracleParameter("RC2", OracleType.Cursor);
param.Direction = ParameterDirection.Output;
cmd.Parameters.Add(param);
OracleDataAdapter adapter = new OracleDataAdapter(cmd);

DataSet ds = new DataSet();
adapter.Fill(ds);

OK!

如果是Oracle9之前的版本,需要定义包含REF CURSOR的包.
例如:
create or replace package GLOBAL_OBJECT is
type RC_OBJECT is ref cursor;
end GLOBAL_OBJECT;

create or replace procedure GET_PERSON
(
RC1 out RC_OBJECT ,
RC2 out RC_OBJECT
)
is
begin
open RC1 for select * from PERSON;

open RC2 for select * from PERSON;
end GET_PERSON;
