The language has been around since 1986 and is worth learning. SQL is a special-purpose programming language designed for managing data held in a databases.

You will learn how to use SQLite, SQL queries, RDBMS and more of this cool stuff! Related course: Master SQL Databases with Python Thus, you can write much cleaner code while working with SQLite and C#.In this tutorial you will learn how to use the SQLite database management system with Python.

Return svc.Find(employeeFilter).ToList() Public List GetEmployeesByTechnology(string technology)ĮmployeeFilter.Add(x => x.Technology, technology) ĮmployeeService svc = new EmployeeService() Return new EmployeeService().GetById(id) New EmployeeService().Update(existingEmployee) public void UpdateEmployee(Employee existingEmployee) Similarly, you can update, search employees as given in the sample methods given below. Please notice, the employee class has been passed to BaseService as an entity. Return new EmployeeService().Add(newEmployee) ĮmployeeService class looks very clean and simple. Call the add method in employee service. Public long InsertEmployee(Employee newEmployee) Public string JobDescription ', generatedEmployeeId) I will explain this custom attribute little later.Įmployee model class looks like this. Another point I must mention at this moment is, each property will be decorated with a custom attribute called DbColumn, which denotes it to be a table column in the database.

These model classes will be exactly similar to entity classes in case of an Entity framework with SQL Server. The properties will be same as the column's name. The model class name will be exactly the same as the table name (“Employee”).

This class library will contains all the model classes.

Now, we have to create our solution and tiers. SQLiteDemo.db and table name and schema is shown below. In our case, we have only one table inside the database – Employee. Also, how to optimize the code and its maintainability.įirst of all, let’s create a SQLite database, using any SQLite manager.How to use reflection and generic to create your custom and extensible ORM to interact with SQLite database.How to architect a SQLite +C# client Application without any ORM.In the article given below, I will show you. Thus, can we use quasi-lambda codes to interact with such file system DB? Can we avoid hardcoded table/column names from our C# code? If you ask me these questions, I would say 'absolutely”. After working on Linq and Entity framework-like ORM, it feels quite irritating to write inline queries for CRUD operation in SQLite DB. Thus, we are compelled to use inline queries.

There is no proper Entity Framework support available, as of now. Unlike SQL Server, this doesn’t require any Service to interact with the database but the real problem occurs, when we try to interact with SQLite DB in C#. SQLite is open source file system database.
