Watch Learning Golang: Relational Databases - Introduction to database/sql Video Tutorial

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 == Relevant links * Example code: https://github.com/MarioCarrion/videos/tree/0e574a88b82ea18400ca525e01afd98d9f014e18/2021/11/17 * PostgreSQL driver and toolkit for Go: https://github.com/jackc/pgx * Previous Episode: "Learning Golang: Functional Options / Default Configuration Values Pattern": https://youtu.be/fe8vJSIzWss * "Software Architecture in Golang: Security - Databases, SQL Injection and Permissions" https://youtu.be/eixRIh80-F8 * "Learning Golang: Context package: Cancellations, Deadlines and Request-scoped values" https://youtu.be/mgJMIZsWfB4 == All Go/Golang video series covered * Playlist "Learning Go": https://www.youtube.com/playlist?list=PL7yAAGMOat_F7bOImcjx4ZnCtfyNEqzCy * Playlist "Software Architecture in Go": https://www.youtube.com/playlist?list=PL7yAAGMOat_GCd12Lrv_evJ3Zhv1dl8B- * Playlist "Learning Go/Golang Concurrency Patterns" https://www.youtube.com/playlist?list=PL7yAAGMOat_Fhj_px_DzNzTsXs-mRwv1t * Playlist "Building Microservices in Go": https://www.youtube.com/playlist?list=PL7yAAGMOat_Fn8sAXIk0WyBfK_sT1pohu * Playlist "GoTools and Packages": https://www.youtube.com/playlist?list=PL7yAAGMOat_HEEOvH99agDs_5g51A0Ls3 * Playlist "Testing in Go": https://www.youtube.com/playlist?list=PL7yAAGMOat_HSeW4zF0uRL9EaHadE4ZZq == Socials * https://twitter.com/MarioCarrion * https://www.instagram.com/mario.carrion * https://linkedin.com/in/MarioCarrion 00:00 - Start 02:34 - Importing pgx for PostgreSQL in Golang 07:00 - Connecting to PostgreSQL using pgx in Golang 11:10 - Selecting row in PostgreSQL using pgx in Golang 15:20 - Inserting records in PostgreSQL using pgx in Golang 20:50 - Selecting multiple rows in PostgreSQL using pgx in Golang 24:40 - Conclusions --- Who am I: Hello👋🏼!
