Скачать или смотреть Learning Golang: Relational Databases - Transactions with PostgreSQL

Let's learn about using Transactions when working with Relational Databases in Go/Golang using the standard library, using "database/sql", and a concrete driver, which in this case is going to be "pgx"; and also a different third-party implementation that is coming from the "pgx" package itself!

This episode covers the methods used in Go/GoLANG to interact with transactions specifically, when using "database/sql" in the standard library we can use:

Begin a Transaction: "DB.BeginTx" (also "DB.Begin" works)
Commit a Transaction: "Tx.Commit"
Rollback a Transaction: "Tx.Rollback"

Also when using "jackc/pgx" we can directly use:
"Conn.BeginTx", or
"Conn.BeginTxFunc"

When using Transactions in Go/Golang the important things to keep in mind are:
Do not call the original "db" after the transaction was created, use "tx" instead.
Do not call directly "BEGIN", "COMMIT" or "ROLLBACK", instead use the methods defined in the API
