人大金昌netcore适配,调用oracle模式下存储过程\包,返回参数游标

三项超标2024-04-04 10:17

cs 复制代码

 using KdbndpConnection conn = new KdbndpConnection("Host=192.168.133.221;Port=54321;Database=db1;Pooling=true;User ID=system;Password=123");
 conn.Open();
 //存储过程调用也是类似
 using var cmd = conn.CreateCommand();
 cmd.CommandText = "模式.包名称.存储过程名称";
 cmd.CommandType = CommandType.StoredProcedure;
 //参数1是普通入参
 var p1 = cmd.CreateParameter();
 p1.ParameterName = "p1";
 p1.Direction = ParameterDirection.Input;
 p1.Value = "123";
 cmd.Parameters.Add(p1);
 //参数2是一个select结果的游标
 var p2 = cmd.CreateParameter();
 p2.ParameterName = "Resultlist";
 p2.Direction = ParameterDirection.Output;
 p2.KdbndpDbType = KdbndpTypes.KdbndpDbType.Refcursor;
 cmd.Parameters.Add(p2);

 //执行
 cmd.ExecuteNonQuery();

 //游标数据获取
 var curName = p2.Value;
 cmd.CommandText = $"fetch all in \"{curName}\"";
 cmd.CommandType = CommandType.Text;
 //生成dt
 DataTable dt = new DataTable();
 using var adp = new KdbndpDataAdapter(cmd);
 adp.Fill(dt);

官网下载的包有问题,使用这个包就ok
