Sqldb

The sqldb module defines a supercharged native sql.DB driver that simplifies configuration and add some usefull methods. It aims to minify code repetition that the database/sql" module can create.

Overview

The sqldb module offers:

• Simplified configuration
• A TryConnection method for pinging your database, triggering an error if the timeout is exceeded
• Convenient methods to streamline SQL database queries

Concepts

Easily configure your connector with the provided Conf structure and its factory methods:

type Conf struct {
	Driver string `yaml:"driver"` // Database driver (e.g., "mysql", "postgres", etc.).
	DSN    string `yaml:"dsn"`    // Data Source Name (DSN) for connecting to the database.
}

Usage

Configuration

The sqldb.Conf uses a YAML tags, it's easy to load SqlDB config with configuration file in your project

type Conf struct {
	Driver string `yaml:"driver"` // example: postgres, mysql
	DSN    string `yaml:"dsn"` // connection string (format depends on the driver, read the associated documentation)
}

Example DSN:

• postgres: user=postgres password=example dbname=postgres host=localhost port=5432 sslmode=disable TimeZone=UTC
• mysql: root:example@tcp(localhost:3306)/dbtest?loc=UTC&tls=false&parseTime=true (WARNING: parseTime=true is require)

Create new connector

To create new SqlDB Connector use this function with as configuration the structure sqldb.FactoryConnector(c sqldb.Conf) (*sqldb.Connector, error) and try connection with sqldb.Connector.TryConnection(t int) err

var config = sqldb.Conf{
	Driver:     "mysql",
	DSN:      	"root:example@tcp(localhost:13306)/dbtest?loc=UTC&tls=false&parseTime=trueword",
}

// Build Connector
connector, err = sqldb.FactoryConnector(config)
if err != nil {
	return fmt.Errorf("fail to init SqlDB connector: %w", err)
}

// Test connection
err = connector.TryConnection(10)
if err != nil {
	return fmt.Errorf("fail to ping SqlDB: %w", err)
}
