在Linq中使用ExecuteCommand到带有Transaction的Sql

Posted 2021-04-05

我想以下面的方式使用ExecuteCommand()更新表：

using (var context = new FMDataContext())
{
    // how do I execute below two steps in a single transaction?
    context.ExecuteCommand("Update Table1 set X = 1 Where Y = 2");
    context.ExecuteCommand("Update Table2 set X = 3 Where Y = 4");
}

有一个答案here为此，但它是为EF，我使用Linq To Sql。

答案

你需要在你的电话周围跨越TransactionScope：

using (TransactionScope transaction = new TransactionScope())
{

    using (var context = new FMDataContext())
    {            
        context.ExecuteCommand("Update Table1 set X = 1 Where Y = 2");
        context.ExecuteCommand("Update Table2 set X = 3 Where Y = 4");
    }
    transaction.Complete();
}
