大批量插入引起事務中止或超時

在做有幾十萬行的批量插入了兩個數據庫（以編程方式，相同的情況下，相同的模式）和每個數據庫約17桌，我幾乎總是會收到Transcaction異常終止或超時過期異常。

如何

使用的EntityFramework 6的數據情況下，我在數據庫上運行一個SqlCommand。

using (var tran = new TransactionScope(TransactionScopeOption.Required, transactionOptions)) 
{ 
    context.Database.ExecuteSqlCommand(
     "BULK INSERT " + table + 
     " FROM '" + Directory + 
     table + ".csv' WITH (DATAFILETYPE = 'widechar', FIRSTROW = 2, FIELDTERMINATOR = '[TERM]', ERRORFILE = '" + 
     Logfile + DateTime.Now.ToString(@"yyyy-MM-dd") + "-R" + DateTime.Now.Second + DateTime.Now.Millisecond + 
     ".txt', ROWTERMINATOR = '\n', KEEPNULLS, TABLOCK)"); 

    tran.Complete(); 
}

設置超時值

爲了打擊我一直面臨着我同時設置命令和事務超時在8分鐘的問題。任何異常都會在所述十八分鐘過去之前發生。

context.Database.CommandTimeout = 1080; 
TransactionOptions transactionOptions = new TransactionOptions(); 
transactionOptions.Timeout = TimeSpan.FromMinutes(18);

全部例外

怎麼辦

我找不到在SQL Server中類似的任何設置或（使用SSMS ）。您將請求幫助提供答案的任何額外數據。

有關SQL過程中timout命令的執行，我會建議您設置的CommandTimeout通過的ObjectContext中的DbContext包裹：

((IObjectContextAdapter)context).ObjectContext.CommandTimeout = 1080;

這種做法一直爲我工作。
