PromotionDescription = qo.Plan_Description. To change the default command timeout, use the connection string option Default Command Timeout. To provide isolation between programs accessing a database concurrently. Because this task is a heavy process, EF caches queries by the query tree shape, so that queries with the same structure reuse internally-cached compilation outputs. Select(g => g.OrderBy(gi => gi.Plan_Number).First()) To provide reliable units of work that allow correct recovery from failures and keep a database consistent even in cases of system failure, when execution stops (completely or partially) and many operations upon a database remain uncompleted, with unclear status. When EF receives a LINQ query tree for execution, it must first 'compile' that tree, e.g. Select first from each group to get unique details It allows performing CRUD operations without having to write SQL queries. Group promotions By Plan Number ('Promotion ID') Entity Framework is an ORM made by Microsoft. Query = query.Where(q => q.Start_Date >= inputStartDate)
filter promotion results that don't match Promotion Start Date Query = query.Where(q => q.Store_Number = inputStoreNum) filter promotion results that don't match Store Num Query = query.Where(q => q.Sku_Number = inputSKU) This section details some common themes for making your queries faster, and pitfalls users. Querying efficiently is a vast subject, that covers subjects as wide-ranging as indexes, related entity loading strategies, and many others.
filter promotion results that don't match SKU# Tracking, no-tracking and identity resolution. Var query = db.vw_Web_Promotion.AsQueryable() Using (DWH_Entities db = new DWH_Entities()) Log.Info("Client requested QueryPromotion") Private List QueryPromotion(int? inputSKU, int? inputStoreNum, DateTime? inputStartDate) Var qUniqueOffers = query.GroupBy(q => q.Plan_Number).ToList()
If there is a more efficient way please let me know.Īnd it hangs at, because it skips all the conditional bits: I've included the Method I use to acquire the desired data. NET 5.x API and deploying to an Azure App Service, then you might run into an issue where it.

which I cannot figure out how to use in this situation. NET/.NET Core Applications If you’re using ASP.NET Core 2.x/3.x and. If your problem is with the former, I suggest you to use database pagination. Your connection timeout not available, the excute time less than 240 seconds obviously. Most solutions I find on the specific error recommend connection string modifications OR something along . Your data is too large to query, which execute time larger than 240 seconds, then you got this eroor 2. The timeout period elapsed prior to completion of the operation or the server is not responding."
