c#使用oracle存储过程获取结果集实例

存储过程：

create or replace PACKAGE FIRSTPAGE AS

/* TODO enter package declarations (types, exceptions, methods etc) here */
type v_cursor is REF CURSOR;
procedure getnumber(re_cursor out v_cursor);
END FIRSTPAGE;

create or replace PACKAGE BODY FIRSTPAGE AS

procedure getnumber(re_cursor out v_cursor) AS
BEGIN
/* TODO implementation required */
open re_cursor for
select * from testable;
END getnumber;

END FIRSTPAGE;

C#代码：

public DataSet GetTableByProcedure()
{
OracleConnection con = new OracleConnection(_connectionString);
OracleCommand cmd = new OracleCommand();
cmd.Connection = con;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "firstpage.getnumber";

OracleParameter sp = new OracleParameter("re_cursor", OracleType.Cursor);
sp.Direction = ParameterDirection.Output;
cmd.Parameters.Add(sp);

OracleDataAdapter da = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);

cmd.Dispose();
con.Close();
con.Dispose();

return ds;

}
