<?xml version="1.0" encoding="UTF-8"?> 1. 接口為ExecuteStoredProcedure(string storedProcedureName, params ObjectParameter[] parameters) 2. 參數為存儲過程名字， 及輸入值。 3. 思路：創建連接（連接中指定了是Sql/MySql/ODBC等等）； 創建通用DbCommand；更改Text以及Type；添加通用Parameter（DBParameter是抽象類，因此需要判斷connection類型）；判斷連接狀態（需Open）； 調用Execute方法； 關閉連接。 4. 實現如下:
// In V1 of the EF, the context connection is always an EntityConnection EntityConnection entityConnection = (EntityConnection)protocolDB.Connection; // The EntityConnection exposes the underlying store connection DbConnection storeConnection = entityConnection.StoreConnection; DbCommand command = storeConnection.CreateCommand(); command.CommandText = storedProcedureName; command.CommandType = CommandType.StoredProcedure; if (storeConnection is SqlConnection) { foreach (ObjectParameter p in parameters) { command.Parameters.Add(new SqlParameter { ParameterName = p.Name, Value = p.Value }); } } else if (storeConnection is MySqlConnection) { foreach (ObjectParameter p in parameters) { command.Parameters.Add(new MySqlParameter { ParameterName = p.Name, Value = p.Value }); } } else { return enProtocolDBReturnCodes.OPERATION_FAILED; } bool openingConnection = command.Connection.State == ConnectionState.Closed; if (openingConnection) { command.Connection.Open(); } command.ExecuteNonQuery(); if (openingConnection && command.Connection.State == ConnectionState.Open) { command.Connection.Close(); }
