Скачать или смотреть Learning Golang: Relational Databases - Introduction to database/sql

Let's learn about accessing Relational Databases in Go/Golang using the standard library, specifically using "database/sql" and a concrete driver, which in this case is going to be "pgx".

This first episode introduces you to "database/sql" the default way to access Relational Databases in Go/Golang, I will cover the basic instructions to:
Open a Connection using "sql.Open"
Ping the connection using "db.PingContext" (also "db.Ping" works)
Query one row using "db.QueryRowContext" (also "db.QueryRow" works)
Query multiple rows using "db.QueryContext" (also "db.Query works)
Inserting records using "db.ExecContext" (also "db.Exec" works)

This is the foundation of future videos that will come, also a few things to keep in mind regarding Relational Databases in Go/Golang:
Go/Golang does not provide any official drivers, however it provides database/sql
Typically drivers implement only that interface, but some like pgx add their own
Nowadays we should be using the context-like methods when accessing databases
