跟一個第三方系統作接口,須要插入幾百萬條數據到Oracle數據庫。html
下載Oracle的Managed版本的ODP.NET組件,只須要一個Oracle.ManagedDataAccess.dll這個DLL就能夠搞定了,使用數組參數的方式,能夠毫秒級插入幾百萬條數據。

示例代碼以下:sql
string[] codeValue = new string[shopList.Count]; string[] nameValue = new string[shopList.Count]; int j = 0; foreach (Shop shop in shopList) { codeValue[j] = shop.Code; nameValue[j] = shop.CName; j++; } command = new OracleCommand(sql, connection); sql = string.Format("INSERT INTO SHOP_ALL VALUES(:Code,:CName)"); command.ArrayBindCount = shopList.Count; //批量插入記錄的條數,必定要賦值 command.CommandText = sql; OracleParameter codePara = new OracleParameter("Code", OracleDbType.NVarchar2); codePara.Direction = ParameterDirection.Input; codePara.Value = codeValue; command.Parameters.Add(codePara); OracleParameter nameParameter = new OracleParameter("CName", OracleDbType.NVarchar2); nameParameter.Direction = ParameterDirection.Input; nameParameter.Value = nameValue; command.Parameters.Add(nameParameter); command.ExecuteNonQuery();
