Postgres is one of the popular SQL databases owing to its many features and ease of use.
Postgres is ACID-compliant with features like Multi-Version Concurrency Control, async replication, nested transactions, and write-ahead logging.
Along with many others, these features make Postgres the go-to SQL database management system.
The Go ecosystem is home to many packages for interacting with various DBMS, including Postgres.
Go provides the built-indatabase/sqlpackage for working with SQL databases using database drivers.
Using Go data structures, you could integrate popular third-party ORMs like GORM for easy interaction with your database.
GORM provides functionality for auto migrations, logging, prepared statements, transactions, and sharding.
The package takes the code-first approach using structs and other built-in data types.
GORM provides database drivers for popular DBMS.
Youll use thelogpackage to log errors to your console and thefmtpackage to print output.
Youll need a connection string to connect to yourPostgres databasein the running environment.
Using a struct makes it easier to change and test different values, especially in cases of dependency injection.
It returns the connection instance and an error depending on the connection status.
you’re able to open a database connection with GORM using theOpenmethod.
It returns a connection instance and an optional error.
Youll need to create a new connection instance to ping the database.
you’ve got the option to ping the database with thePingmethod of the database instance.
ThePingmethod returns any errors ornilif the connection was successful.
GORM also provides a SQL builder for building raw SQL, which is helpful for unsupported operations.
