I have a table with 3 columns like below：

```
DeliveryDate(string) | 2020-06-16
DeliveryTime(string) | 20:00:00
EstimateDeliveryDateTime(DateTime) | 2020-06-15 20:00:00.232

```

I wrote below condition in LINQ, expect it convert to sql by ef core, but failed.
`EstimateDeliveryDateTime > Convert.ToDateTime(DeliveryDate + DeliveryTime)`

I know AsEnumberable(). But I want this condition to be executed in db, is it doable in LINQ or not?
