Building dynamic queries with EasyQuery and Entity Framework

Here we describe how EasyQuery helps to implement a query building UI for creating custom, dynamic queries in .NET projects which use Entity Framework (6.x)

Entities page

This page describes entities participating in the data model and their attributes.

Hide some entities and/or attributes

Here we explain how to implement different ways to limit the quantity of entities and attributes shown in Data Model

Upgrade instructions. From Version 3.x to 5.x for .NET Framework 4.x projects

Dynamic queries for ASP.NET Core projects with Entity Framework Core

It takes a few minutes to add a new page with all necessary UI for building dynamic queries and to setup a middleware that will process all requests from that page, convert those request to the queries to your DB and return the result set back for visualization. This step is necessary to get the trial keys for EasyQuery framework. One for ASP.NET Core packages and another one - for EasyQuery.JS scripts. To simplify this task EasyQuery includes a Razor UI library package ( Korzh.EasyQuery.RazorUI ) that contains several predefined pages which you can use in your projects. For example, there is an "advaced search" page which is available via /EasyQuery/AdvancedSearch .

Creating data model dynamically with code

-Data Model- object is an essential part of EasyQuery framework. However, sometimes you need to add some entities, entity attributes or operators to the existing model or to fill it from scratch using DB metadata information got from another source. In these cases, you can use EasyQuery API to build the model dynamically. Finally, we add entities and entity attributes. Here is an example of creatin a small data model: two tables (Customers and Orders) with one link between them, 2 entities (Customer and Order correpondingly) and a few attributes in each entity.
