我正试图弄清如何像以前使用ODP.Net(df.groupby(['column1']).agg({'column2': sum, 'column3': sum,....})System.Data.Odbc)和参数化一样使用ODBC(OracleCommand)批量插入多条记录查询。

我使用OracleConnection做过一些研究之后,发现完美的东西是这样的:

odp.net

}

我尝试对odbc使用相同的逻辑,使用string query = @"insert into Customer ( surname, firstName, emailAddress) values (:surname, :firstName, :emailAddress)"; oracleConnection.Open(); using (var command = oracleConnection.CreateCommand()) { command.CommandText = query; command.CommandType = CommandType.Text; command.BindByName = true; // In order to use ArrayBinding, the ArrayBindCount property // of OracleCommand object must be set to the number of records to be inserted command.ArrayBindCount = bulkData.Count; command.Parameters.Add(":surname", OracleDbType.Varchar2, bulkData.Select(c => c.Surname).ToArray(), ParameterDirection.Input); command.Parameters.Add(":firstName", OracleDbType.Varchar2, bulkData.Select(c => c.FirstName).ToArray(), ParameterDirection.Input); command.Parameters.Add(":emailAddress", OracleDbType.Varchar2, bulkData.Select(c => c.EmailAddress).ToArray(), ParameterDirection.Input); int result = command.ExecuteNonQuery(); if (result == bulkData.Count) returnValue = true; } command.Parameters.AddWithValuecommand.Parameters.Add传递数据,但是仍然难以理解如何管理它。有没有人尝试过?
