C#调用Oracle带输出数据集的存储过程

1、创建一个带输出数据集的Oracle存储过程

create or replace procedure PRO_test(in_top in number,cur_out out sys_refcursor) is

--查询指定记录条数的数据，并返回总共记录数，返回多个数据集

begin

open cur_out for

SELECT * FROM dept_dict where rownum < in_top;

end PRO_test;

 

2、C#调用

Pu_Sys.GetConnObject con = new Pu_Sys.GetConnObject();

OracleConnection conn = new OracleConnection(con.Get_ConnStr());

OracleCommand Dcomm = new OracleCommand("PRO_TEST", conn);

Dcomm.CommandType = CommandType.StoredProcedure;

OracleParameter DpPass = new OracleParameter();

DpPass.Value = 5;

DpPass.Direction = System.Data.ParameterDirection.Input;

DpPass.ParameterName = "in_top";

Dcomm.Parameters.Add(DpPass);

OracleParameter DpOut = new OracleParameter("cur_out", OracleType.Cursor);

DpOut.Direction = System.Data.ParameterDirection.Output;

Dcomm.Parameters.Add(DpOut);

OracleDataAdapter Da = new OracleDataAdapter(Dcomm);

DataSet Ds = new DataSet();

try

{

Da.Fill(Ds);

}

catch (Exception)

{

}

conn.Close();

conn.Dispose();
