Interactive Online SQL And Databases Training for Beginners | Simpliv

Strong yet friendly, deep yet funny, and very visual. This is what this course on SQL and database heavy lifting is! Learn SQL in depth and the fundamentals of database with loads of practical knowledge and just enough theory. Queries in MySQL and SQLite, and code in Python are taught practically.

Description
Prerequisites: No prerequisites are needed for the SQL commands and DBMS fundamentals. Basic knowledge of programming in Python would be helpful if you want to run the source code in the course-ending project.

Taught by Stanford-educated, ex-Googlers. This team has decades of practical experience in quant trading, analytics and e-commerce.

Your bodyguard for when data gets too big, this course is strong but friendly, funny yet deep, animated yet thoughtful.

Let’s parse that.

Your bodyguard for when data gets too big: Most business folks (and quite a few engineers) use Excel as a basic tool of decision making and modeling, but when you can't fit the data you'd like into an Excel spreadsheet that you can easily open, its time to move to a database.

The course is strong but friendly: This course will help you move to a database without being intimidated by the new environment. Don't let anyone tell you that any dataset is too large or too complicated for you to understand (and people will try, most likely)

The course is funny yet deep: It goes really deep into the topics that folks often find hard to understand, such as joins, aggregate operators and interfacing with databases from a programming language. But it never takes itself too seriously:-)

The course is very visual : most of the techniques are explained with the help of animations to help you understand better.

This course is practical as well : Queries are explained in excruciating detail, indices are demystified, and potentially career-limiting traps (Drop, Alter) are marked with bright yellow tape markers so you can steer clear.

The course is also quirky. The examples are irreverent. Lots of little touches: repetition, zooming out so we remember the big picture, active learning with plenty of quizzes. There’s also a peppy soundtrack, and art - all shown by studies to improve cognition and recall.

What's Covered:

SQL In Great Depth
Database Fundamentals and Just Enough Theory
Practical Examples - Queries in MySQL and SQLite, and code in Python
Who is the target audience?

Yep! Data analysts who would like to really get down and dirty with the data
Yep! Business folks and executives looking to make their decision making more data-driven, and seeking the technical knowledge to do so.
Yep! Students of Computer Science and Computer Engineering looking to understand database concepts for the first time
Yep! Software engineers who need to understand and interface with databases from programming languages in their work
Basic knowledge
This course will cover generic (non-system-specific) SQL, but will also conduct exercises using 2 different database technologies: MySQL and SQLite. Installation and use of both these will be explained in-depth
What will you learn
Explore large datasets and uncover insights - going far beyond the Excel, deep into the data
Model and create a database for day-to-day use
Interface with databases from a programming language such as Python
Have the comfort and confidence needed to load data and use both GUI and a command line interface for database operations
Fully understand and leverage joins, subqueries, aggregates, indices, triggers, stored procedures and other major database concepts

Migrate Entity Framework Core to SQL Database on Startup

Migrate Entity Framework Core to SQL Database on Startup

This ASP.NET Core tutorial explains how to migrate Entity Framework Core to SQL Database on Startup. How to automatically migrate database changes from code in ASP.NET Core using Entity Framework Core from the Startup.cs file. Use the EF Core DB Context Service to automatically migrate database changes.

Example code tested with ASP.NET Core 3.1

This is a super quick example of how to automatically migrate database changes from code in ASP.NET Core using Entity Framework Core from the Startup.cs file.

Solution

Register the EF Core DB Context as an ASP.NET Core Service

The Entity Framework Core DB Context is registered as a service with the ASP.NET Core Dependency Injection (DI) system from the ConfigureServices() method of the Startup.cs file.

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    services.AddDbContext<DataContext>(x => x.UseSqlite("Data Source=LocalDatabase.db"));

    ...
}

Use the EF Core DB Context Service to automatically migrate database changes

An instance of the EF Core DB Context service is injected as a parameter into the Configure() method of the Startup.cs file, the DB Context instance is then used to apply any pending migrations to the database by calling the Database.Migrate() method.

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, DataContext dataContext)
{
    // migrate any database changes on startup (includes initial db creation)
    dataContext.Database.Migrate();

    ...
}
Extra Info

While updating the tutorial from an EF Core InMemory database to SQLite I ran into some difficulties trying to automatically run database migrations from the Startup.cs. At first I was following a tutorial on the MS Docs website that called services.BuildServiceProvider().GetService<MyDatabaseContext>().Database.Migrate(); from within the ConfigureServices() method, but this resulted in the following warning in the console when I ran the application:

Startup.cs(39,13): warning ASP0000: Calling 'BuildServiceProvider' from application code results in an additional copy of singleton services being created.
Consider alternatives such as dependency injecting services as parameters to 'Configure'.
