Question

这是我的代码：

TransactionCollection transactions = new TransactionCollection();
transactions.Where("next_action", "RESEND");
transactions.Where("job_id", CurrentJob.Id);
transactions.Load();

我真的希望它说next_action是RESEND或者next_action是TARGET。感谢。

基本上我想要一个像这样的选择状态：

select * from transactions where job_id = 1 and (next_action = 'RESEND' OR next_action = 'TARGET');

或

select * from transactions where job_id = 1 and next_action IN ('RESEND', 'TARGET');

如果您使用的是SubSonic 2.1或更高版本，则可以利用AndExpression和OrExpression。对于您的第一个示例，以下内容应该有效：

TransactionCollection transactions = DB.Select().From(Transaction.Schema)
  .Where("job_id", CurrentJob.Id);
  .AndExpression("next_action")IsEqualTo("RESEND")
  .Or("next_action")IsEqualTo("TARGET")
  .ExecuteCollection<TransactionCollection>()

使用亚音速时如何进行或选择？
